The information output to the information output unit 14 is such that a video signal is output to, for example, a monitor, an audio signal is output to, for example, a speaker, and a data signal is output to, for example, a computer. Also,
The information output to the input / output control unit 16 is stored in the storage unit 15. As described above, the service addition including the related information and the time information in the information (contents) such as video and audio, which is transmitted from the sender side and reproduced in the information synthesizing unit 13 of the information receiving apparatus 100 in a synthesized form. The service information to which the information is added is stored in the storage unit 1 via the input / output control unit 16.
5, the data user can output the stored service information to the information output unit 14 via the input / output control unit 16 and use it.

Specifically, for example, a case will be described in which the service information is an electronic program guide up to one week ahead, including a moving image. When an electronic program guide including a moving image is received as service information, the data user displays a program table created based on the service information on a screen of a display device (not shown) via the information output unit 14, Used to select programs. As an electronic program guide including a moving image, when a cursor displayed on a program table displayed on the screen is moved by a remote control to designate a predetermined program, a moving image related to the program is displayed on the screen. Things are conceivable. In such an electronic program guide, information such as a broadcast channel of the program and an identifier indicating the program and time information, that is, a start time and an end time of the program are added to each program. When the user selects a program, a recording reservation or the like is executed using the additional information.

Here, if the service information transmitted from the sender is continuously stored without performing any processing on the service information stored in the storage unit 15,
Since a large number of unnecessary service information remains in the storage unit 15, the problem described in the subject of the present application occurs. That is, in the example of the electronic program guide, a program that has already been broadcast is also displayed in the program guide, which is an obstacle to the selection of a program, making it difficult to select a program. Since the large storage capacity of the storage unit is used by the moving image information of the program and the like, there is a problem that the memory cannot be effectively used.

In the information receiving apparatus according to the first embodiment,
When the information sender receives the service information to which the time information is added, the service information is stored in the storage unit 15 via the input / output control unit 16, and thereafter, the input / output control unit 1
6 performs the following operation. That is, under the control of the CPU 103, the time information of the service information stored in the storage unit 15 is fetched through the information input / output unit 101 at predetermined time intervals, and the time information is stored in the time information comparison unit 108. The discard control unit 106 compares the current time with the current time counted by the clock unit 107, based on the comparison result of the time information comparison unit 108. Storage unit 15
Outputs an instruction to delete the service information.
In response to the information deletion instruction, the storage unit 15 deletes part or all of the service information.

Here, the input / output control unit 16 receives new service information instead of performing the comparison processing operation of the time information every predetermined period as described above, and stores it in the storage unit 15. May be performed each time the data is stored, or each time a data user inputs a comparison processing command from outside.

Further, here, when the storage unit 15 receives the delete instruction from the discard control unit 106 and deletes the service information,
In addition to physically eliminating the signal of the service information from the storage medium of the storage unit 15, the reading of the signal of the service information is disabled. This means that the signal of the service information cannot be read from the storage medium and cannot be viewed by the data user.

In the example of the electronic program guide described above, the input / output control section 16 periodically or at a specific time stores the storage section 15.
The time information added to each program information of the electronic program guide, which is the service information stored in the electronic program guide, is read out and compared with the current time information counted by the clock unit 107, and the current time is added to the program information. When the time information exceeds the time information, that is, when the program information is already in the past, the program information to which the time information is added is stored in the storage unit 15.
Remove from.

If the storage medium is physically removed from the storage medium as a method of deletion, it is possible to eliminate the state where the storage medium is no longer occupied by information whose utility value is low. In this case, new information can be stored in an empty area after the information has been deleted, so that the storage medium can be effectively used. Also,
If the method of deletion is a method of preventing display on the display device, instead of physically erasing the storage medium, the data user will not have to view the unnecessary program information on the screen. Can be avoided.

Next, as another specific example, a case where the service information is product information will be described. For example,
When receiving service information in which the end of a bargain period (a bargain period) of a product is added as time information to catalog-like information describing the state and function of the product, the information receiving apparatus according to the first embodiment is It works as follows.
That is, the input / output control unit 16 reads the time information added to the product information, which is the service information stored in the storage unit 15, periodically or at a specific time, and the clock unit 107 counts this. The current time information is compared with the current time information, and when the current time exceeds the time information added to the product information, that is, when the bargain period has already ended, the product information with this time information is added. Delete from the storage unit 15. Here, as for the method of deleting the product information, in addition to deleting all the information of the product information to be deleted, other information such as the product name is left in the product information while the other information is deleted. Is also good. By leaving only the product name of the product in this way, a product list can be created.

Next, an information receiving apparatus according to a first modification of the first embodiment will be described with reference to FIGS.
However, FIG. 1 is completely the same as the above basic example except for the input / output control unit 16, and the description thereof is omitted.

FIG. 3 shows the input / output control unit 16 of the information receiving apparatus.
FIG. 3 is a diagram showing the configuration of FIG. In FIG. 3, reference numeral 109 denotes a set time information holding unit that holds set time information input from the outside. In the description of the basic example of the first embodiment, the case where the time information added to the service information is compared with the current time counted by the clock unit provided in the receiving device has been described. In the modified example, the time information added to the service information is compared with the set time information held in the set time information holding unit 109. Here, as the set time information from outside, the data user sets time information from outside, and compares the set time information with the time information added to the service information. .

Further, as a second modified example of the first embodiment, instead of the data user inputting the set time information, the information sender transmits the set time information via a broadcast or a telephone line. The set time information stored is stored in the set time information holding unit 10.
9 and compare the set time information with the time information added to the service information.

In such a modification, the processing (deletion processing) of the service information to which the time information has been added can be performed on the basis of an arbitrary time other than the current time, and the service information can be processed on a freer basis. It can be processed.

As described above, according to the information receiving apparatus of the first embodiment, at least the time information is added as additional information on the sender side, and the information receiving apparatus receives the service information transmitted. After the service information is stored in the storage unit 15, the time information is read from the service information stored in the storage unit 15, and the time information and the set time information set in the receiving device (for example, the current time or an external time) are read. And time information set by the time information comparison unit 108, and based on the result of the comparison, processing is performed on part or all of the service information corresponding to the time information. Information stored in the storage medium of the receiving device can be automatically and appropriately deleted, thereby enabling effective use of the storage medium. Rutotomoni, it is possible to improve the usability of information by the data user. The above operation flow is shown in FIG.

Reference numeral 150 denotes a reference time holding unit that holds a time (period) serving as a reference for comparison in the time information comparing unit 108.

Next, the operation of the information receiving apparatus according to the third embodiment will be described. The information receiving apparatus of the first embodiment processes (deletes) service information transmitted with time information added from the sender of the service information. The device processes (deletion processing) both service information transmitted from the service information sender with the time information added thereto and service information transmitted from the service information sender without the time information added. ).

First, the channel decoding unit 8 performs digital demodulation and error correction processing on the signal transmitted on the transmission path 7. The demultiplexing unit 9 demultiplexes the signal output from the channel decoding unit 8, and the separated signal is output to the information decoding unit 10 and the related information processing unit 11. The information output to the information decoding unit 10 is decoded into a video or audio signal or the like. The information combining unit 13 combines information output from the information decoding unit 10 and the related information processing unit 11 and outputs the combined information to the information output unit 14 and the input / output control unit 16. These operations are the same as the operations of the corresponding parts of the information receiving apparatus according to the first embodiment.

The information output to the input / output control unit 16 is stored in the storage unit 15. Here, the input / output control unit 16
Under the control of the time information addition control unit 18, when the service information is stored in the storage unit 15, the current time counted by the clock unit 107 is added to the service information as time information, and the service information to which the time information is added is added. The information is stored in the storage unit 15. As described above, related information (service additional information) is added to information (contents) such as video and audio that is transmitted from the sender side and reproduced in the information synthesizing unit 13 of the information receiving apparatus 100 in a synthesized form. The input / output control unit 16 adds the time information to the service information,
5, the data user can output the stored service information to the information output unit 14 via the input / output control unit 16 and use it.

Next, the operation of processing (deletion processing) of service information in the information receiving apparatus according to the third embodiment will be described. The input / output control unit 16 is controlled by the CPU 103 every predetermined period or at a specific time.
Time information of service information stored in the storage unit 15,
That is, the time information added by the input / output control unit 16 when the service information is stored in the storage unit 15 is stored in the information input / output unit 10.
1 and the time information is compared with the current time counted by the clock unit 107 in the time information comparison unit 108. Based on the comparison result of the time information comparing unit 108, the discarding control unit 106 determines that the current time has passed from the time indicated by the time information added to the service information for a predetermined time held in the reference time holding unit 150 or more. For, the command to delete the service information is output to the storage unit 15. In response to the information deletion instruction, the storage unit 15 deletes part or all of the service information.

Here, the storage unit 15 deletes the service information in response to the deletion command from the discarding control unit 106, which means that the service information is physically deleted from the storage medium of the storage unit 15 as in the first embodiment. Other than eliminating the signal, the service information signal cannot be read out, or the data user cannot read the service information signal from the storage medium in the storage information management unit on the storage medium. This also means that it cannot be viewed.

The time held in the reference time holding unit 150 is
When the data user is to input, the data user inputs a desired period (for example, 20 days) for retaining the service information in the storage unit from an input operation unit (not shown), and performs input / output control. The unit 16 captures the set value via the external signal input unit 102 and stores the set value in the reference time holding unit 150. As a result, the service information processing (deletion process) operation deletes the service information that has been stored in the storage unit 15 and has passed for 20 days or more.
The storage medium can be effectively used.

The flow of the above operation is shown in FIGS.
(b) Steps 26 to 37 are shown. Further, the time (period) held in the reference time holding unit 150 may be anything inputted by the data user or sent by the service information provider.

Next, the information receiving apparatus according to the modification of the third embodiment of the present invention sets the time held in the reference time holding unit 150 as
This is transmitted by the service information provider. In this case, the provider of the service information transmits the expiration date of the service information by broadcasting, a telephone line, or the like. As a method of transmitting by broadcasting, in addition to a method of adding the expiration date to the service information as additional service information and transmitting the information, information for specifying the service information and data including the expiration date are broadcast separately from the service information. There is a way to do it. In the case of transmission via a telephone line or the like, data specifying the service information and data including the expiration date are transmitted. The input / output control unit 16 captures the expiration date information from the information synthesizing unit 13 via the information input / output unit 101 or via the external signal input unit 102 and stores it in the reference time holding unit 150. As a result, the service information processing (deletion processing) operation deletes the service information that has been stored in the storage unit 15 and has passed the expiration date set by the service information provider, and is stored in the information receiving apparatus. The medium can be effectively used. Among the above operations, the flow of operation when the service information provider transmits the reference time is shown in FIG.

As a specific example where the service information provider transmits the reference time, a case where the service information is product information will be described. For example, when the service information in which the expiration date (for example, 31 days) of the information is added as the service additional information to the catalog-like information that describes the state and function of the product is received, the information reception according to the third embodiment is performed. The device operates as follows. That is, the input / output control unit 16 reads the time information added when the service information is stored in the storage unit 15 periodically or at a specific time, and stores the time information (A) and the expiration date (B ) Is compared with the current time information (C) counted by the clock unit 107, and when A + B <C,
That is, when the expiration date set by the service information provider has passed, this product information is deleted from the storage unit 15. Here, as for the method of deleting the product information, in addition to deleting all information of the product information to be deleted,
You may make it delete other information, leaving the information of the product name in the product information. By leaving only the product name of the product in this way, a product list can be created.

Here, in the description of the third embodiment, the case where the current time is added to the service information as time information when the service information is stored in the storage unit 15 has been described. The time when the stored service information is used may be added to the service information as time information. In this case, when a certain time has elapsed after the last use of a certain service information, the service information is As a result, the service information that has not been used for a long time can be efficiently and automatically arranged.

Further, the time when the service information stored in the storage unit 15 is used for the first time may be added to the service information as time information. In this case, after a certain service information is used for the first time, This service information will be deleted when a predetermined time has elapsed. In the case of such a configuration, for example, when the information sender provides service information, this service information is repeatedly used for one hour after the data user first uses the service information. It is possible to provide a service information providing method in which the service information can be used, but thereafter the use is disabled.

As described above, according to the information receiving apparatus according to the third embodiment, in the information receiving apparatus which receives the service information transmitted by adding the additional information on the sender side,
A storage unit 15 for storing the received service information, and when storing the service information in the storage unit 15,
Alternatively, when the service information stored in the storage unit 15 is read, the time information is stored in the storage unit as additional information, and the added time information is read from the service information stored in the storage unit 15. Time information and set time information set in the receiving device (for example, current time or time information set externally)
Is compared by the time information comparing unit 108, and based on the result of the comparison, processing is performed on part or all of the service information corresponding to the time information, so that the information is stored in the storage medium of the information receiving apparatus. The information thus obtained can be automatically and appropriately deleted, whereby effective use of the storage medium can be achieved, and the usability of the information by the data user can be improved.

Embodiment 4 The information receiving apparatus according to the fourth embodiment of the present invention determines the processing of the service information based on the data size added to the service information, and is divided into two types depending on the difference in the method of comparing the data sizes.

Hereinafter, FIGS. 6 and 7 and FIGS.
This will be described with reference to FIG. First, a basic example of the fourth embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a diagram showing a configuration of an information receiving apparatus according to Embodiment 4 of the present invention. In FIG. 6, the same reference numerals as those in FIG. Data size information generating means for generating data size information
Reference numeral 21 denotes a data size information processing unit that processes the data size information separated by the demultiplexing unit 9 and outputs the processed data size information to the information combining unit 13.

In the figure, the same reference numerals as those in FIG. 2 denote the same or corresponding parts. Reference numeral 110 denotes a data size comparison unit that compares the data size added to the plurality of service information stored in the storage unit 15.

Next, the operation of the information receiving apparatus according to the basic example of the fourth embodiment will be described. The information receiving apparatus according to the fourth embodiment processes (deletes) service information transmitted with the data size information added from the service information sender.

When transmitting the service information on the information sender side, when the transmission signal to which the data size information indicating the size of the service information is added is received via the transmission path 7, first, the channel decoding unit 8 Performs digital demodulation and error correction processing on the signal transmitted through the transmission path 7.
The demultiplexing unit 9 demultiplexes the signal output from the channel decoding unit 8, and the separated signal is output to the information decoding unit 10, the related information processing unit 11, and the data size information processing unit 21. The information synthesizing unit 13 synthesizes information output from the information decoding unit 10, the related information processing unit 11, and the data size information processing unit 21.
And output to the input / output control unit 16. The information output to the input / output control unit 16 is stored in the storage unit 15. As described above, the video and the video transmitted from the sender side and reproduced in the synthesized form in the information synthesizing unit 13 of the information receiving apparatus 100 are displayed.
The service information in which related information and data size information are added as service additional information to information (contents) such as voice is stored in the storage unit 15 via the input / output control unit 16, and the data user can use the stored service. Information can be output to the information output unit 14 via the input / output control unit 16 and used.

Next, the operation of service information processing (deletion processing) in the information receiving apparatus according to the basic example of the fourth embodiment will be described. The input / output control unit 16 transmits the data size information of the plurality of service information stored in the storage unit 15 via the information input / output unit 101 under the control of the CPU 103 at predetermined time intervals or at a specific time. The data size comparison unit 110 compares the plurality of pieces of data size information taken in with each other, and for the largest data size, issues a command to delete the service information to which the data size information has been added.
06 to the storage unit 15. In response to the information deletion instruction, the storage unit 15 deletes part or all of the service information. Thereby, the service information having the largest data size among the service information stored in the storage unit 15 is deleted periodically or at a specific time, and by repeating this operation, the storage unit 15 has a relatively small data size. Since small service information remains, a larger number of service information can be stored in a storage medium having the same storage capacity. That is, when the data user desires to retain a larger number of service information, the storage medium can be effectively used.

In the above description, a description has been given of a case where the data size information of a plurality of service information is compared to delete the one having the largest data size. ) May be deleted, and in this case, the same effect as that of deleting the data having the largest data size can be obtained.

The discard control unit 106 outputs a command to the storage unit 15 to delete the service information to which the data size information has been added for a data size larger than the set data size as compared with the size information. In response to the information deletion instruction, the storage unit 15 deletes part or all of the service information. As a result, only the service information whose data size is equal to or smaller than the data size set by the data user is stored in the storage unit 15, and the data user holds a larger number of service information by the data user. When it is desired to use the storage medium, the storage medium can be effectively used.

[0100] In the above description, the one in which the data size added to the service information is larger than the set data size is deleted. However, the one in which the data size is smaller than the set data size may be deleted. Frequently, in this case, when the data user places more importance on the richness of the data of each service information than on the number of service information, the storage medium can be effectively used.

Further, the upper limit and the lower limit of the data size may be held in the set data size holding unit 111, and the service information having the data size larger than the upper limit and the service information smaller than the lower limit may be deleted. In the case where the data user desires to hold the service information whose data size is within the range of the predetermined data size, the storage medium can be effectively used. The flow of the above operation is shown in steps 1 and 2 in FIG. 26A and steps 50 to 56 in FIG.

As described above, in the information receiving apparatus according to the fourth embodiment, at least the information indicating the data size of the information is added as the additional information, and the information receiving apparatus receives the service information transmitted from the sender side. After the received service information is stored in the storage unit 15, information on the data size of the plurality of service information is read from the service information stored in the storage unit 15, and the data size of the plurality of service information is changed to the data size. The comparison is performed by the comparison unit 110, and based on the comparison result,
Since the information processing is performed for a part or all of the service information of any of the plurality of service information, the information stored in the storage medium of the information receiving apparatus can be automatically and appropriately deleted. As a result, the storage medium can be effectively used, and the usability of the information by the data user can be improved.

Further, in the information receiving apparatus according to the modification of the fourth embodiment, at least information indicating the data size of the information is added as additional information, and information for receiving the service information transmitted from the sender side is added. In the receiving device, after storing the received service information in the storage unit 15, information on the data size is read out from the service information stored in the storage unit 15, and the read data is compared in the data size comparison unit 110 by the setting data size holding unit 111. Is compared with the set data size held in the information receiving apparatus, and based on the comparison result, the information processing is performed on part or all of the service information. And can be properly deleted based on desired criteria, thereby effectively utilizing the storage medium. It is possible to possible to improve the usability of information by the data user.

The demultiplexing unit 9 demultiplexes the signal output from the channel decoding unit 8, and the separated signal is output to the information decoding unit 10 and the related information processing unit 11. The information combining unit 13 combines information output from the information decoding unit 10 and the related information processing unit 11 and outputs the combined information to the information output unit 14 and the input / output control unit 16. The information output to the input / output control unit 16 is stored in the storage unit 15. As described above, related information (service additional information) is added to information (contents) such as video and audio that is transmitted from the sender side and reproduced in the information synthesizing unit 13 of the information receiving apparatus 100 in a synthesized form. The service information is stored in the storage unit 15 via the input / output control unit 16, and the data user can output and use the stored service information to the information output unit 14 via the input / output control unit 16. it can.

Next, an operation of processing (deletion processing) of service information in the information receiving apparatus according to the first example of the fifth embodiment will be described. Each time the data user operates an operation input unit (not shown) and the service information stored in the storage unit 15 is read and used, the counter control unit 112 of the input / output control unit 16 controls the counter 19 to use the data. Let the number be counted. The count value (restore number information) counted by the counter 19 is added to the service information stored in the storage unit 15 as additional information. On the other hand, the number-of-times comparing unit 114 reads the number of times of re-storing added to the service information from the storage unit 15 and compares the number of times of re-storing with the number of times stored in the set number of times holding unit 113.

Based on the comparison result of the number comparison unit 114, the discard control unit 106 determines whether the number of times of reading added to the service information exceeds the number of times stored in the set number of times storage unit 113. Outputs an instruction to delete the service information. In response to the information deletion instruction, the storage unit 15 deletes part or all of the service information. As a result, the service information read (used) a predetermined number of times is deleted from the storage unit 15, and the storage medium of the information receiving device can be effectively used. The flow of the above operation is shown in steps 1 and 2 in FIG. 26A and steps 57 to 64 in FIG.

Next, an information receiving apparatus according to a second example of the fifth embodiment of the present invention will be described. This information receiving apparatus is very similar to the first example, and only the differences will be described. In the description of the first example of the fifth embodiment,
Although the service information is read from the storage unit 15 and the number of times of re-storing the service information in the storage unit is added to the service information, the information receiving apparatus according to the second example is configured to read the service information from the storage unit 15. The number of times the service information has been read is added to the service information. The number of times of reading is stored in the counter 19 of FIG. The above operation flow is shown in FIG.
Steps 1 and 2 of (a) and steps 65 to 70 in FIG. 35 are shown.

Here, the number of times set in the set number holding unit 113 may be input by the data user operating an input operation unit (not shown), or the information sender may transmit the broadcast or broadcast data. The set number of times may be transmitted together with the information specifying the service information via a telephone line or the like. As a method of transmitting by broadcasting, there is a method of adding the set number of times to the service information as service additional information and transmitting the information, and a method of transmitting information specifying the service information and data including the set number of times separately from the service information. There is a way to do it. When transmitting via a telephone line or the like, data specifying the service information and data including the set number of times are transmitted.

As described above, according to the information receiving apparatus of the fifth embodiment, in the information receiving apparatus to which the additional information is added and which receives the service information transmitted from the sender,

The number-of-times comparing unit 114 compares this number-of-times information with the set number-of-times information set in the receiving apparatus (number-of-times information externally set by a data user or a service information sender).
, And based on the comparison result, processing is performed on part or all of the service information corresponding to the number-of-times information, so that the information stored in the storage medium of the information receiving apparatus is automatically , Can be appropriately deleted, thereby enabling effective use of the storage medium and improving the usability of the information by the data user. The service information in the fifth embodiment performs the same operation as the above operation regardless of the presence or absence of the additional information added by the sender.

Embodiment 6 FIG. The information receiving apparatus according to the sixth embodiment of the present invention determines the processing of the service information by comparing the data usage price of the service information, and is classified into two types depending on the difference in the comparison method. Hereinafter, each will be described with reference to FIGS. 11 and 12 and FIGS. 11 and 13.

First, a first example of the sixth embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a diagram showing a configuration of an information receiving apparatus according to a first example of Embodiment 6 of the present invention. In FIG. 11, the same reference numerals as those in FIG. Price information generating means 31 for generating price information indicating a price necessary to use the price information, which processes price information separated by the demultiplexing unit 9 and outputs the processed price information to the information synthesis unit 13 Department.

FIG. 12 is a diagram showing a detailed configuration of the input / output control unit 16 of the information receiving apparatus according to the first example of the sixth embodiment. 12, the same reference numerals as those in FIG. 2 denote the same or corresponding parts. Reference numeral 115 denotes a price comparison unit that compares the usage prices of a plurality of pieces of service information stored in the storage unit 15.

Next, the operation of the information receiving apparatus according to the first example of the sixth embodiment will be described. The information receiving apparatus according to the first example of the sixth embodiment processes (deletes) service information to which price information is added and transmitted from the service information sender based on the usage price. is there.

When the information sender transmits the service information and receives via the transmission path 7 a transmission signal to which price information indicating the use price of the service information has been added, first, the channel decoding unit 8 , Digital demodulation and error correction processing of the signal transmitted through the transmission path 7. The demultiplexing unit 9 demultiplexes the signal output from the channel decoding unit 8 and outputs the demultiplexed signal to the information decoding unit 1.
0, the related information processing unit 11 and the price information processing unit 31 are output. The information synthesis unit 13 synthesizes information output from the information decoding unit 10, the related information processing unit 11, and the price information processing unit 31, and outputs the information output unit 14, and the input / output control unit 1.
6 is output. The information output to the input / output control unit 16 includes:
It is stored in the storage unit 15. In this way, the information related to the information (content) such as video and audio and the price information transmitted from the sender side and reproduced in the information synthesizing unit 13 of the information receiving apparatus 100 are added to the service additional information. Is added to the input / output control unit 16
The data user can output the stored service information to the information output unit 14 via the input / output control unit 16 and use it.

Next, an operation of processing (deletion processing) of service information in the information receiving apparatus according to the first example of the sixth embodiment will be described. The input / output control unit 16 transmits the price information of the plurality of service information stored in the storage unit 15 through the information input / output unit 101 under the control of the CPU 103 at predetermined time intervals or at a specific time. Ingest,
The received plurality of pieces of price information are compared with each other in the price comparison unit 115, and for the highest price, a command to delete the service information to which the price information is added is output from the discard control unit 106 to the storage unit 15. I do. In response to the information deletion instruction, the storage unit 15 deletes part or all of the service information. As a result, of the service information stored in the storage unit 15, the one with the highest data usage price is deleted periodically or at a specific time, and by repeating this operation, the storage unit 15 stores the data usage price. However, relatively inexpensive service information remains. Therefore, when a data user desires to hold service information with a lower data usage price, the storage medium can be effectively used.

In the above description, the price information of a plurality of pieces of service information is compared to delete the one with the highest data use price. May be deleted up to the integer). In this case as well, an effect similar to that of deleting the highest data usage price can be obtained.

In addition, the cheapest data usage price,
Alternatively, up to the n-th (n is an integer of 2 or more) data may be deleted in ascending order of the data use price. In this case, by repeating the deletion processing operation, the service information whose data usage price is relatively expensive remains in the storage unit 15, so that the data user can use the service information whose data usage price is higher. Can be effectively used when it is desired to hold the storage medium.

Next, an information receiving apparatus according to a second example of the sixth embodiment of the present invention will be described with reference to FIGS. However, FIG. 11 is the same as the first example except for the input / output control unit, and a description thereof will be omitted. FIG. 13 is a diagram showing a configuration of the input / output control unit 16 of the information receiving apparatus according to the second example of the sixth embodiment. In FIG. 13, reference numeral 116 denotes a reference price holding a reference price input from the outside. It is a holding unit. In the description of the first example of the sixth embodiment, the case where price information added to a plurality of pieces of service information is compared with each other is shown. The information is compared with the reference price held in the reference price holding unit 116. Here, it is assumed that the data user can input an arbitrary value from the input operation unit (not shown) as the reference price from outside. The input / output control unit 16 controls the storage unit 15 under the control of the CPU 103 every predetermined period or at a specific time.
The price information of the service information stored in the storage unit 11 is fetched through the information input / output unit 101, and is input to the reference price holding unit 11

Output. Upon receiving the information deletion instruction, the storage unit 15 deletes part or all of the service information. As a result, only the service information whose data usage price is lower than the price set by the data user is stored in the storage unit 15, and the data user holds the service information whose data usage price is lower than the predetermined price. This makes it possible to effectively use the storage medium when it is desired to save the data, and to prevent a data user from erroneously using service data having a high data usage price that is not expected.

Although the above description has been made on the case where the data usage price is higher than the reference price is deleted, the data usage price lower than the reference price may be deleted. If the data user desires to retain service information whose data usage price is equal to or lower than a predetermined price, the storage medium can be effectively used.

Further, the upper limit and the lower limit of the price may be held in the set price holding unit 116, and the service information whose data usage price is higher than the upper limit and the service information lower than the lower limit may be deleted. , Data consumers
When it is desired to hold service information whose data usage price is within a predetermined price range, the storage medium can be effectively used.

As described above, in the information receiving apparatus according to the first example of the sixth embodiment, at least the price information indicating the data usage price of the information is added as the additional information, and the service transmitted from the sender side is added.

Embodiment 8 FIG. The information receiving apparatus according to the eighth embodiment of the present invention manages the use of the data of the received service information at predetermined usable points, and is classified into four types depending on the management method. Hereinafter, they will be described with reference to FIGS.

First, an information receiving apparatus according to a first example of the eighth embodiment of the present invention will be described with reference to FIGS. FIG. 16 is a diagram illustrating a configuration of an information receiving apparatus according to a first example of Embodiment 8 of the present invention.
The same reference numerals as those in FIG.
Numeral 51 denotes point information generating means for generating point information including a data name, usable points, actual use points, and a point-of-use point table. 13 is a point information processing unit that outputs the information to the point 13.

FIG. 17 is a diagram showing a detailed configuration of the input / output control unit 16 of the information receiving apparatus according to the first example of the eighth embodiment. 17, the same reference numerals as those in FIG. 2 denote the same or corresponding parts. Reference numeral 125 denotes use of service information data and service information processing (deletion processing) based on the point information of the service information stored in the storage unit 15.
Is a data usage management unit that manages

Next, the operation of the information receiving apparatus according to the first example of the eighth embodiment will be described. The information receiving apparatus of the first example of the eighth embodiment receives service information to which point information is added and transmitted from the service information sender side, stores the service information in a storage unit, and stores the service information based on the point information. , And manages the use of the service information data and the processing (deletion processing) of the service information. here,
The point information added on the information sender side is added to the content of service information, which is information actually used by the data user, for example, a database, a game, and the like. It includes a name, usable points, used results points, and a point-in-use point table. On the information sender side, a certain value (for example, 1000 points) is set as the usable point and transmitted. Similarly, 0 points are used for the actual usage points that are cumulatively added by using the data, and the points required for using the content are stored in the point-in-use table (for example, 100 points for the database and 50 points for the game at a time). Is set and sent.

The information receiving apparatus transmits a transmission signal obtained by adding the point information including the usable point, the actual use point table, and the point-of-use point table set as described above and the data name on the transmission side of the information to the transmission path. 7, first, the channel decoding unit 8 digitally demodulates and error-corrects the signal transmitted on the transmission path 7. The demultiplexing unit 9 demultiplexes the signal output from the channel decoding unit 8 and outputs the demultiplexed signal to the information decoding unit 10, the related information processing unit 11, and the point information processing unit 51. The information synthesizing unit 13 synthesizes information output from the information decoding unit 10, the related information processing unit 11, and the point information processing unit 51.
And output to the input / output control unit 16. The information output to the input / output control unit 16 is stored in the storage unit 15. As described above, the video and the video transmitted from the sender side and reproduced in the synthesized form in the information synthesizing unit 13 of the information receiving apparatus 100 are displayed.
The service information in which the related information and the point information are added as the service additional information to the information (content) such as the voice is stored in the storage unit 15 via the input / output control unit 16,
The data user can output the stored service information to the information output unit 14 via the input / output control unit 16 and use it.

Next, the operation of the use of service information and the processing of service information (deletion processing) in the information receiving apparatus according to the first example of the eighth embodiment will be described. When the data user uses the content, the data user specifies information desired to be used among the contents of the service information. In response to the designation by the data user, the data use status management unit 125 of the input / output control unit 16 first reads out the point information of the corresponding service information from the storage unit 15 and stores the current content point as the current use point. Then, it is determined whether or not the value obtained by adding the points added by using is equal to or less than the value of the available points. If the value obtained by adding the points to be added by the use of the content to the actual use points is larger than the usable point value, the use of the content by the data user is prohibited, and the display device (not shown) displays A message such as "No available points remain" is displayed to inform the data user that the specified information cannot be used. On the other hand, when the value obtained by adding the points to be added by the current use of the content to the use result points is equal to or less than the usable point, the operation shifts to the content use processing operation. Then, when the use of the content is completed, the data usage management unit 125 refers to the point-of-use point table in the point information and, for example, if the used content is a database, 100 points, and if the used content is a game, If so, 50 points are added to the usage result points and stored in the storage unit 15.
Then, the data usage management unit 125 repeats the above processing every time the data user uses the content. When the usage result point reaches the usable point, the data use state management unit 125 instructs the discard control unit 106 to end the usable point. Is output. Discard control unit 1 receiving this end signal
06 outputs a command signal to the storage unit 15 to delete the service information for which the usable point has ended, and in response to this, the storage unit 15 deletes the corresponding service information.

As described above, in the embodiment according to the first example of the eighth embodiment, the point information including at least the data name, the data usable point, the data use actual point, and the point-in-use point table as the additional information. In the information receiving apparatus for receiving the service information transmitted from the sender side, the storage unit 15 for storing the received service information is provided, and the data of the service information stored in the storage unit 15 is used. At the time, the points determined in the point-of-use point table are added to the data use actual points, and when the data use actual points reach the data usable points, a part or all of the service information is referred to as the information. Since the processing is performed, the information stored in the storage medium of the information receiving device is Depending on usage, automatically properly it can be removed, thereby it is possible to achieve effective use of the storage medium, can facilitate customer management of the service provider.

Next, an information receiving apparatus according to a second example of the eighth embodiment will be described with reference to FIGS. However, the second example is similar to the first example, and the differences will be described.

In the first example of the eighth embodiment, service information to which point information including a data name, a data usable point, a data use actual point, and a point-of-use point table is added is received, and the data is usable. Although the service information is processed based on the result of the comparison between the points and the data usage points, the information receiving apparatus in the second example also uses the point information including the data name, the data available points, and the point-in-use point table. Is received, and when the data user uses the content, the number of points specified in the point-of-use point table is subtracted from the data available point. Even with such a configuration, the same effect as that of the first example of the eighth embodiment can be obtained. The configuration of the input / output control unit 16 of the information receiving apparatus having such a configuration is basically the same as that of the first example of the eighth embodiment shown in FIG. Works like In other words, when the data user specifies the content, the data usage status management unit 125
Reads the point information of the corresponding service information from the storage unit 15 and subtracts the point required for use of the current content from the current data available point. If the data available point is smaller than zero after this subtraction, Disallow the use of content by data consumers,
On the other hand, when the data usable point is equal to or greater than zero, the operation shifts to a content use processing operation. Then, when the use of the content is completed, the data usage management unit 125 refers to the point-in-use table, for example, 100 points if the used content is a database, and 50 points if the used content is a game. Is subtracted from the data available point, and the storage unit 15
To memorize. Then, the data usage management unit 125
Each time the data user uses the content, the above process is repeated, and when the data available point becomes zero, an end signal indicating the end of the available point is output to the discard control unit 106. Upon receiving the end signal, the discard control unit 106 outputs a command signal to the storage unit 15 to delete the service information whose usable point has ended,
In response, the storage unit 15 deletes the corresponding service information.

Here, instead of physically erasing the service information for which the usable point has ended from the storage unit 15, a process of making the service unusable by the data user is performed.
When the data user takes a procedure such as paying the price of points to the service provider, by receiving the usable point rewriting program sent from the service provider side, or by mail from the service provider side By using a data package to be used, the usable point of the service information may be rewritten.

Next, a description will be given of an information receiving apparatus according to a third example of the eighth embodiment with reference to FIG. 16 and FIG. However, the third example is similar to the first example, and the differences will be explained.

In the first or second example of the eighth embodiment, the data available point is transmitted as the additional information of the service information and stored in the storage unit as the data available point. In the third example, a data usable point common to a plurality of pieces of service information is stored in a data usable point holding unit in the information receiving apparatus. In the information receiving apparatus having such a configuration, the service information to which the point-of-use point table is added as the additional information is received from the sender of the service information, and is stored in the storage unit. The configuration of the input / output control unit 16 is basically the same as that of Embodiment 8 shown in FIG. 17, and operates as follows when the data user uses the content. In other words, when the data user specifies the content, the data usage status management unit 125
Reads out the point-of-use point table of the corresponding service information from the storage unit 15, detects the point required for the current use of the content, and subtracts this point from the common data available point held in the data available point holding unit. If the data available point is smaller than zero after the subtraction, the use of the content by the data user is prohibited. On the other hand, if the data available point is zero or more, the operation shifts to the content use processing operation.
Then, when the use of the content is completed, the data use status management unit 125 refers to the point-of-use table and, for example, 100 points if the used content is a database, and 50 points if the used content is a game. Is subtracted from the common data available point. Then, the data use state management unit 125 repeats the above processing every time the data user uses the content. The end signal shown is output. Upon receiving this end signal, the discarding control unit 106 outputs to the storage unit 15 a command signal for deleting service information that requires a point when using the content (service information to which a point-of-use point table is added as additional information). In response, the storage unit 15 deletes the corresponding service information.

Here, instead of deleting the service information when the common data available point becomes zero,
The sender of the service information (service provider) is notified via a communication line or the like that the common data usable point has become zero, and the service provider receiving the notification deletes the specific service information. A configuration may be adopted in which data indicating what to do is transmitted, and specific service information is deleted when the data is received on the information receiving device side. In this case, when the specific service information is deleted (discarded), a predetermined price is assigned to the common data available point held in the data available point holding unit as the price of the service information deletion (service point from the service provider). The points may be added.

Next, an information receiving apparatus according to a fourth example of the eighth embodiment will be described with reference to FIGS. However, the fourth example is similar to the first example, and the differences will be described.

In the above-described example, a data available point common to a plurality of pieces of service information is held in the data available point holding unit in the information receiving apparatus, and the data available point stored in the data available point holding unit is stored from the data available point holding unit. Although the point of use defined in the point-of-use point table of the service information is subtracted, in the fourth example, the data use result point holding unit for holding the data use result point is further configured as Service points are added based on the usage points and the data usage points stored in the data usage point storage unit and the data usage points stored in the data usage point storage unit. It is configured to perform information processing (deletion processing).
