[0002]

2. Description of the Related Art Currently, VHS is used as a video / audio recording means.
VTRs (magnetic recording / reproducing devices) of 8 mm type and 8 mm type are widely used. Normally, a VTR has a timer recording function, and if a date and time and a channel of a program to be recorded are designated, the designated program is automatically recorded. It also has the ability to record the same program daily or weekly once specified. Further, various technologies for further enhancing the timer recording function have been disclosed.

As an example of such a conventional technique, Japanese Unexamined Patent Publication No. Hei 4
There is a technique described in JP-A-205834. In this conventional example, for example, the tape is automatically rewound to the recording start position after the timer recording is completed. This allows the user to immediately play the timer-recorded program. Further, when the reserved recording time exceeds the remaining tape amount, the tape is automatically rewound to the beginning and then recording is started. This allows the user to reliably record the reserved program without checking the remaining tape amount.

[0004]

In the conventional timer recording, it is necessary for the user to judge the contents of the program based on the program guide of the newspaper and to decide whether or not to record the program.
However, as the number of channels increases due to digital broadcasting and the like, the time and effort required to search for a desired program among a large number of programs become enormous. In addition, when the latest information is entered in news and weather forecasts, the previous information may become unnecessary, but in the conventional VTR, the user needs to determine whether or not the recorded program is unnecessary, which is troublesome. there were.

A first object of the present invention is to automatically update the latest news only by the user specifying that the reserved program is news at the time of recording reservation and that the inserted tape is exclusively for news. It is to provide a VTR capable of recording.

A second object of the present invention is, in addition to the above functions,
An object of the present invention is to provide a VTR that automatically detects the type of a program and does not require an individual news reservation operation.

A third object of the present invention is to record a new program as to whether or not a program is to be recorded when the user inputs in advance the type and priority of information that he or she needs. It is another object of the present invention to provide a recording / reproducing apparatus which automatically determines a program required by a user by determining which old program should be erased.

[0012]

In the first aspect of the invention, the reserved program data setting means sets whether or not the reserved program is of a specific type (for example, news). The tape code setting means sets whether or not the tape is dedicated to a specific type (for example, news). The tape code recognition means determines whether or not the inserted tape is dedicated to a particular type (for example, news). The recording condition determining means controls so that only news is recorded on the news tape. For news tapes,
The data in the tape contents memory is read out and controlled so that the end tape position of the latest news becomes the recording start position of the next news. However, at this time, when it is determined that there is not enough recording space for the next news, the tape is rewound to the beginning. Furthermore, after the end of recording, rewind to the recording start position. With the above operation, the user can reserve and record many news programs in advance so that the latest news can be played and viewed at any time without waiting for the tape remaining amount.

In the second aspect of the invention, the program data extracting means extracts the program information sent from the broadcasting station by being superimposed on the video signal and stores it in the program memory. The program selecting means selects only a program of a specific type (for example, news) from the data stored in the program memory. The tape code setting means and the tape code recognizing means perform the same operations as in the first embodiment. The recording condition determining means controls so that only the news program selected by the program selecting means is recorded on the news tape. At this time, the recording tape position and the like are controlled in the same manner as in the first embodiment. By this action, the user can watch the latest news at any time without making a recording reservation of an individual news program.

In the third aspect of the present invention, the priority order setting means sets the priority order according to the small classification (politics, economy, sports, etc.) in the news. The elapsed time coefficient setting means acts to lower the priority of the recorded old news. The coefficient recording / reproducing means records the priority order or the elapsed time coefficient corresponding to the program to be recorded in the directory area of the recording / reproducing means and reproduces it. The first priority determining means determines the highest priority program among the programs being broadcast, and the second priority determining means determines the priority of the recorded program and the program being broadcast. Then, a new program is recorded while erasing the recorded programs in ascending order of priority. As a result, the user can always view the favorite and latest news by making more detailed designations such as giving priority to economic news or lowering the priority of sports news whose time has passed.

A video signal processing circuit 8, a servo circuit 9, a date and time code generating circuit 10, a system control circuit 11,
Operation unit 12, memory 13, magnetic heads 14a, 14
b, the reels 15a and 15b, the rotating cylinder 16,
It has a magnetic tape 17, a memory 18, and a time code generating circuit 19. Further, the system control circuit 11 has a recording reservation processing unit 111, a recording content management unit 112, a recording condition determination unit 113, and a recording / playback / display control unit 114.

The operation of the circuit shown in FIG. 1 will be described below. First, a normal recording operation will be described. When the "recording" mode is instructed to the system control circuit 11 from the operation section 12, the recording / playback / display control means 114
Connects the switch 7 to the R side and sends a control signal necessary for recording to the video signal processing circuit 8 and the servo circuit 9. The servo circuit 9 includes a rotating cylinder 16 and a reel 15.
While monitoring the speeds and phases of a and 15b, the rotation of the motor (not shown) is controlled so that they match the standard at the time of recording.

Further, the servo circuit 9 includes reels 15a, 1
The tape length TL and the tape remaining time TZ are calculated by monitoring the rotational speed of 5b and the rotating cylinder 16 and the tape running amount, and the data is sent to the system control circuit 11. TZ is calculated based on the tape running amount during one rotation of each of the supply side reel 15a and the take-up side reel 15b, and the present tape type (T-12
0, T-60, etc.), and the details of the calculation and the determination are described in, for example, Japanese Patent Publication No. 5-5419.
Since it is described in Japanese Patent Publication No. 8, it is omitted here.

On the other hand, the tuner 3 responds to a channel switching signal from the recording / playback / display control circuit 114 of the system control circuit 11 only with the radio wave of the channel selected from the radio waves input from the signal input terminal. It selectively receives and demodulates to obtain a video signal S1. The information code adding circuit 6 inserts the information code sent from the recorded content management means 112 of the system control circuit 11 into the vertical blanking period of the video signal S1, and the video signal S2.
Occurs.

The video signal S2 is subjected to signal processing for recording in the video signal processing circuit 8, and the rotary cylinder 16
It is supplied to the magnetic heads 14 a and 14 b attached to the magnetic tape 17 and recorded on the magnetic tape 17. As described above, since the switch 7 is connected to the R side, the video signal S1 is O
It is sent to the SD circuit 4.

The OSD circuit 4 converts the character data input from the recording / playback / display control means 114 of the system control circuit 11 into a character signal synchronized with the video signal S1, and superimposes the video signal S1 on the video signal S1. The signal is output to the signal output terminal 2. The video signal output from the video signal output terminal 2 is connected to an external monitor (not shown), and the screen during recording is displayed together with character information. Also, the OS
In some cases, the D circuit 4 may output a video signal containing only text information on the blue background according to an instruction from the system control circuit 11.

Next, the operation during normal reproduction will be described. When the operation section 12 instructs the system control circuit 11 to perform the "playback" mode, the recording / playback / display control means 114 connects the switch 7 to the P side, and
A control signal necessary for reproduction is sent to the video signal processing circuit 8 and the servo circuit 9. The servo circuit 9 monitors the speed and phase of the rotary cylinder 16 and the magnetic tape 17 and controls the motor so as to create an optimum reproduction state. The signal recorded on the magnetic tape 17 is reproduced by the magnetic heads 14a and 14b attached to the rotary cylinder 16, and processed for reproduction in the video signal processing circuit 8 to become a video signal S3. As described above, the switch 7 is connected to the P side during reproduction, and the video signal S3 is input to the OSD circuit 4. The OSD circuit 4 performs the same processing as at the time of recording, and outputs a video signal of only characters or a video signal in which characters are superimposed to the video signal output terminal 2.

By the way, the time code generating circuit 19 is
The value is reset to 0 at the beginning of the tape, and the numerical value increases as the tape runs during recording. This numerical value is output to the recorded content management means 112 of the system control unit 11. At the time of reproduction, the information code separation circuit 5 sends the data of the time code included in the information code separated from the reproduction signal S3 to the recorded content management means 112 of the system control circuit 11. The time code generation circuit 19 loads and stores the value of the reproduction time code. When recording from the middle of the tape, the time code is generated so as to continue to the loaded value.

The specific recording / reproducing servo operation and signal processing method are the same as those of the conventional VHS or 8 mm VTR, and since they are described in detail in many documents, their details are omitted. The information code addition circuit 6 and the information code separation circuit 5 are often not provided in a normal VTR, but as a technique for inserting an information code in the vertical blanking period of a video signal, it is widely adopted in US broadcasts and the like. VITC (Vertical Int), which is used as the time code for closed captions and commercial VTRs.
Since techniques such as erval Time Code) are generally known, detailed description thereof will be omitted here.

Next, recording reservation will be described. FIG. 2 shows a processing flowchart of the system control circuit 11 at the time of recording reservation. "Recording reservation" from the operation unit 12
Is instructed, the interrupt process of step S101 is executed and the process proceeds to step S102. In step S102, the recording reservation processing unit 111 writes the kth reservation data in the reservation memory 18 according to the data input by the user from the operation unit 12. Here, k is the recording reservation processing means 11 of the system control circuit 11 for one reserved program.
1 is a reservation number that is sequentially assigned from 1.

As the reservation data, the recording start date and time YTS
(K), recording end date / time YTE (k), recording channel Y
CH (k), recording mode YMD (k), news flag YNF (k) and the like are provided.

The recording mode YMD (k) indicates standard recording or long-time recording. The news flag YNF (k) is a flag indicating whether or not the reserved program is news, and YNF (k)
(K) = 1 indicates that the reserved program is news, and Y
NF (k) = 0 indicates that the reserved program is other than news.

Next, the recording reservation processing means 111 determines in step S103 whether or not there is a tape designation instruction,
When there is an instruction of "tape designation" from the operation unit 12, the process proceeds to step S104. When there is no "tape designation" instruction, the process proceeds to step S104. In step S104, the tape number m according to the data from the operation unit 12
After writing the tape classification code TCL (m) of the tape No. in the reserved memory 18, the operation is returned to the normal operation.

For example, when TCL (m) = 1, a news recording dedicated tape is used, when TCL (m) = 2, a news recording prohibited tape is used, and when TCL (m) = 0, a news and general program mixed tape is used. . If there is no "tape designation" instruction, TCL (m) = 0 in step S105.
Is written in the reservation memory 18, and then the normal operation is resumed.

Next, the recording content management function of the system control circuit 11 will be described with reference to FIGS. 3 and 4. FIG. 3 shows a flowchart of the recording process in the system control circuit 11.

The recorded content management means 112 has step S2.
In 01, it is determined whether or not to record. Details of the determination conditions and the like at this time will be described later.

In step S202, the tape number CN (n), which will be described later, the current date and time from the date and time generation circuit 10 (that is, the recording start date and time TS (n)), and the selected channel CH (n ), The current time code TCS (n) sent from the time code generation circuit 19 (this means the time code at the start of recording), the recording mode MD (n), and the news flag NF (n). Data is stored in the tape content memory 13. Here, (n) indicates that it is the n-th program data.

In step S203, the recording content management means 112 sends the data of the tape number, the current date and time, and the current time code to the information code adding circuit 6, and also sends the data to the recording / reproducing display control means 114, and the servo circuit. A control signal required for recording is sent to 9 and the video signal processing circuit 8. The servo circuit 9 and the video signal processing circuit 8 are set to the recording mode. The operation of step S203 corresponds to the normal recording operation described above.

Next, step S for judging the end of the reservation.
At 204, the recording condition determination means 113 causes the date / time generation circuit 10 to output the current date and time data and the reservation memory 1.
The data of the reserved recording end date and time from 8 is compared, and if they match, the process proceeds to step S205. Step S20
5, the recorded content managing means 112 determines that the current date and time (which means the recording end date and time TE (n)) and the current time code (that is, the time code TCE (n) at the end of recording). Are stored in the tape content memory 13.

Then, in step S206, a signal for stopping is sent to each unit. In step S207, the TCL data is read from the reserved memory 18 and it is determined whether or not the current tape is for news only. If it is only for news, the recording content management means 112 rewinds to the tape position at the start of recording in step S208. This can be done by rewinding the tape while monitoring the time code value sent from the information code separation circuit 5 and stopping when the time code value TCS (n) at the start of recording becomes equal.

FIG. 4 is a flow chart of processing in the system control circuit 11 when the contents of the tape are displayed as a list on the television screen and the program specified by the user is cued.

When the tape is inserted into the VTR, step S
The interrupt process of 303 enters, and the process proceeds to step S304.
Perform preliminary playback of tape. This is a process of reproducing the tape for several seconds and reading the tape number and the time code from the information code separated from the reproduced video signal S3 in the information code separation circuit 5 at that time. At this time, the servo circuit 9 calculates the tape length TL and sends it to the system control circuit 11. After playing for a few seconds, the tape is rewound for a few seconds.

Next, in step S305, it is determined whether or not the tape number can be read. Of course, when a new tape is inserted, the tape number cannot be read. In this case, the tape number is set in step S312. This is executed by searching the tape content memory 13 for the maximum value of the set tape number and adding 1 to the value. Initially, the tape number is set to 1 when no data is stored in the tape content memory 13. Next, in step S315, the data of the tape length TL is written in the tape content memory 13. Then, it returns to the normal operation. That is, the operation unit 12 waits for an instruction such as “play”, “fast forward”, “rewind”, “power off”, or the like.

When the tape which has already been recorded is inserted, it is determined that the tape number is detected in step S305. Therefore, the process proceeds to step S306, and the operation section 12 waits for the "display of contents" instruction. To do. When the instruction of "displaying the table of contents" is sent, the table of contents is displayed in step S307. This is executed by reading the data in the tape content memory 13, converting it into character data and sending it to the OSD circuit 4. On the monitor connected to the video signal output terminal 2, for example, a table of contents screen as shown in FIG. 5 is displayed. The table of contents screen shows the tape number, the program number recorded on the tape, the recording date and recording start time of each program, the channel number, the recording time, and the recording mode. The user specifies from the operation unit 12 which program the user wants to cue while viewing the table of contents screen.

When the "cue playback of the nth program" is designated, the command is received in step S308, and the process proceeds to step S313. In step S313, the start time code of the n-th program read from the tape content memory 13 is compared with the time code at the current tape position read in step S304, and the tape is fast-forwarded or wound in accordance with the size relationship between them. A control signal is sent to the servo circuit 9 to return it. The information code separation circuit 5 extracts the time code in the reproduction signal S3 even during fast-forwarding or rewinding and sends it to the system control circuit 11. Then, when the time code in the reproduction signal S3 and the start time code of the nth program match, a control signal is sent to the servo circuit 9 and other parts so as to stop the tape running. When the above cueing step S313 is completed, the process proceeds to step S314. In step S314, the control signal necessary for the reproducing operation is sent to the servo circuit 9 and other parts. When step S314 ends, the normal operation is resumed.

On the other hand, when the user specifies "stop cue of m-th program" from the operation unit 12 while looking at the table of contents screen in step S307, the command is received in step S309, and the process proceeds to step S310. Step S3
In step 10, the same operation as step S313 is performed, and after the head is cued, the operation is stopped. Further, when an instruction of “display tape number list” is received from the operation unit 12, the process proceeds to step S302 by the interrupt process of step S301. In step S302, data is read from the tape content memory 13 and the tape number data set up to the present is converted into a character code and sent to the OSD circuit 4. Since the OSD circuit 4 converts the sent character data into a video signal and outputs it to the video signal output terminal 2, a list of tape numbers is displayed on the monitor screen.

Next, the recording determination step S2 in FIG.
Details of 01 will be described with reference to FIG. 6 is shown in FIG.
The detailed flowchart of S201 in FIG.

When "waiting for reserved recording" is instructed from the operation unit 12, the interrupt process of step S401 is performed, and the process proceeds to step S402.

In step S402, the reserved memory 1
By reading the data of the tape classification code from 8, it is determined whether the tape (tape number is m) currently in the VTR is exclusively for news. In the case of a news tape, the data is read from the reserved memory 18 in step S403 and the news flag YN
It is determined whether there is a reserved program with F (k) = 1. YN
If there is no reserved program with F (k) = 1, no recording is made.

The news flag YNF is stored in the reservation memory 18.
If there are reserved programs with (k) = 1, the recording start date / time YTS is selected from those programs in step S404.
In (k), a program closest to the current date and time generated by the date / time generation circuit 10 (that is, a program to be recorded next) is searched, and the program is set as a recording waiting program. Then, data including the recording start date / time (YTSr), recording end date / time (YTEr), recording channel (YCHr), recording mode (YMDr), and news flag (YNFr) of the corresponding recording waiting program r is temporarily stored in the system control. To do.

In step S405, YDTr, Y
The data of TSr and the data of the current date and time are compared, and it is checked whether or not the time until the start of recording is less than a fixed time (for example, 2 minutes). This time is the next step S40.
This is the maximum time required for rewinding (or fast-forwarding) the tape in step 7 or step S409.

In step S406, the data is first read from the tape content memory 13, and the news flag NF = 1 is searched for a program whose program end date / time DTE is closest to the current date / time (that is, the latest news), and the program ( The end point TCE (p) of the p-th program) is read. Next, the current tape length data TL is read from the tape content memory 13, TL-TCE (p) is calculated, and the calculation result is set as TZ. TZ is TCE (p)
It corresponds to the remaining tape time when recording the next program. Next, YTEr-YTSr is calculated, and the calculation result is set as PL. PL corresponds to the recording time of the program to be recorded next. Finally, by comparing the sizes of TZ and PL, it is checked whether the remaining tape amount is sufficient.

When the remaining tape amount is sufficient (TZ> PL), the flow advances to step S407 to rewind or fast-forward the tape until the tape position reaches TCE (p), that is, the latest news end position. When the remaining tape amount is not sufficient, the process proceeds to step S409, and the tape is rewound to the beginning of the tape.

After that, in step S408, a channel is selected according to the reserved channel YCHr, and then in step S415, the recording start date and time YTSr.
And the match of the current date and time are monitored, and if they match, step S20
Proceed to step 2 to start recording.

If the currently loaded tape is not exclusive to news, it is determined in step S410 whether the tape is exclusive to non-news (TCL (m) = 2?). Y
In the case of es (in the case of a dedicated tape other than news), in step S413, the data is read from the reservation memory 18 and it is determined whether or not there is a program with the news flag YNF = 0 (a program other than news). If not, it will not be recorded.

If there is a program with the news flag YNF = 0, the process proceeds to step S414, the program with the earliest start date / time is searched from the programs with the news flag YNF = 0, and the program is set as the recording waiting program. Then, the recording start date and time (YTSr), the recording end time (YTEr) of the recording waiting program r,
Recording channel (YCHr), recording mode (YMD
r) and the data including the news flag (YNFr) are temporarily stored in the system control 11.

If the determination in step S410 is No (if it is neither a news dedicated tape nor a non-news dedicated tape), the process proceeds to step S411 to determine whether or not there is a reservation. If there is a reservation, the process proceeds to step S412 to search for the program with the earliest start time regardless of the value of the news flag (YNFr), and then steps S404 and S414.
Similarly, the reservation data of the program is temporarily stored as the data of the recording waiting program.

According to the present embodiment described above, it is determined in step S402 in FIG. 6 whether or not the news-only tape is used, and in step S404, only the news is set to be recorded on the news-only tape. A user who wants to see only the news among the users can make a recording reservation for a plurality of news items once, and then can make a reservation recording by inserting a news-only tape into the VTR.

Further, in step S410, it is determined whether or not the tape is a dedicated tape other than news, and step S41
Since it is set to record only programs other than news in step 4, if you do not want to see the news, if you use a dedicated tape other than news, you may run out of tape recording space even if many news recording reservations are included. Absent.

In step S406, it is determined whether there is a sufficient tape remaining amount, and if there is not enough tape remaining for recording the program, the tape is rewound to the beginning in step S409. You don't have to worry about how much time you have left. Further, normally, in step S407, it is set to record the next news from the last point of the latest news, so that the latest news always remains on the tape. Step S
After recording one news program at 208, the tape is rewound to the recording start position of the program, so that the latest news can be immediately reproduced and viewed.

Next, the embodiment of the second invention will be described with reference to FIGS.
This will be described with reference to FIG. FIG. 7 is a circuit block diagram of a specific program recording apparatus showing an embodiment of the second invention.

The video signal S selectively received by the tuner 3 is supplied to the demultiplexing circuit 5.
1 is input. In the present invention, it is assumed that the information code representing the program guide is superimposed within the vertical blanking period of the video signal S1. The system control circuit 11 stores in the program guide memory 32 the program guide information extracted by the program data extracting means 115 from the information sent from the information code separating means 5.

The information code superimposing method is the "standard for television program recording reservation system by teletext" established by the Broadcasting Technology Development Council in Japan in July 1993 (BT.
AT-003), and in the United States EIA TV Data Syst
`` Recommended Practice for E by ems Subcommittee
xtended Data Service Packets "(EIA-608), which can be followed. The former standard is designed to send the program information required for recording within the specifications of teletext currently operating in Japan. The program information includes the broadcasting station name, program start time, and program end. There are time, program name, comment, program identification code and the like. The latter standard uses signals of the same type as closed captions, which are currently being provided as services for the hearing impaired in the United States, to enable program types (education, entertainment, news, etc.) and ratings (general, adult, etc.). ), Etc., not only during recording, but more detailed program information necessary for program selection can be coded and sent.

FIG. 8 shows a part of a flow chart of the recording reservation process by the system control circuit 11 in the second invention, and steps S501 to S503 are steps S101 and S10 in the flow chart of FIG.
This is a process added during 2.

When "designation of program type" is instructed from the operation unit 12 during the recording reservation operation in step S501,
It proceeds to step S502. In step S502,
For example, when "news" is designated from the operation unit 12, a code corresponding to news is written as program type reservation data in the reservation memory 18. Further, the priority order of the channels is set based on the instruction from the operation unit 12 and written in the reservation memory 18.

In step S503, it is determined according to an instruction from the operation unit 12 whether or not there is a normal reservation operation in program units. In the case of "reservation in normal program units", when "reservation by program guide" is next designated from the operation unit 12, the determination in step S504 results in step S505.
Then, the data in the program guide memory 32 is converted into character data and sent to the OSD circuit 4, and the program guide is displayed on the screen. The user specifies a program to be recorded from the operation unit 12 while looking at the screen. System control circuit 11
Writes program data necessary for reservation in the reservation memory 18 according to the designation. After that, the same processing as in FIG. 2 is performed.

FIG. 9 shows a part of the flow chart of the recording judgment processing.
And shown in FIG. FIG. 9 shows step S4 in FIG.
This is a process performed instead of 03. Step S601
In step S602, the system control circuit 11 reads out the program type reservation data from the reservation memory 18, and further reads out the data from the program table memory 32 in step S602 to display the program having the code of the program type (for example, news) designated by the program type reservation data. Determine if there is.

For example, in the case of the above-mentioned US standard, the classification code corresponding to news is defined, so that this is executed by determining the matching of the classification codes. In the case of Japanese teletext, since the corresponding code is not defined, it is determined whether or not the program name has the word "News". If there is no corresponding program, the same determination process is performed after a new program guide is sent and the data in the program guide memory 32 is updated in step S603. If there is a corresponding program, the process proceeds to step S404, the program having the earliest start date and time is selected from the corresponding programs, and the data of the program is set as the recording waiting program data. At this time, if there are a plurality of specific programs (news) within the same time, the program to be broadcast on the channel with the higher priority is set as the recording waiting program according to the above-mentioned channel priority data.

FIG. 10 shows a process performed instead of step S411 in FIG. In step S701, first, data is read from the reservation memory 18, and then in step S702, it is determined whether or not there is a corresponding program (a program having a code of the program type designated by the program type reservation data) in the program table memory 32. To do. If there is no corresponding program, the data in the reservation memory 18 is read in step S703, and it is determined whether there is reservation data.
If there is no reservation data, S in step S704.
Similar to 603, the same determination process is performed after a new program guide is sent and the data in the program guide memory 32 is updated.
If there is reservation data, the process proceeds to step S412. In step S412, the reserved program read from the reserved memory 18 or the program data of the program having the earliest start date / time from the corresponding programs in the program guide memory 32 is set as the recording waiting program data.

According to the second invention described above, not only the same effect as the first invention is obtained, but also if the program type is designated at the time of recording reservation (S502), it is designated in step S602. Since a program of the program type is searched, it is not necessary to make a recording reservation for each program, and the trouble of recording reservation can be saved.

Next, the third invention will be described. FIG.
FIG. 1 is a block diagram of a recording / reproducing apparatus with a recording condition determining function showing a first embodiment of the third invention. This recording / reproducing apparatus with a recording condition determining function is characterized in that a hard disk device which is generally used as a storage device of a computer is used in place of a VTR, and digital broadcasting is used as an example of received broadcast. It is an example of The recording / reproducing apparatus with a recording condition determining function of the present invention includes a signal input terminal 41, a tuner 42, a decoding circuit 43, an OSD circuit 44, a hard disk device 45, a disk control circuit 46, and a buffer memory 47. An information code separation circuit 48, a system control circuit 49, and an operation unit 5
0, a program guide memory 51, a reservation memory 52, a classification code memory 53, a video output terminal 54, a changeover switch 55, and a date / time generation circuit 56. The system control circuit 49 is a recording reservation processing means 491.
Recording content management means 492 and recording condition determination means 49
3, recording / playback / display control means 494, and program code detection means 495.

The operation of the circuit shown in FIG. 11 will be described below. In this embodiment, the broadcasting is digital broadcasting. That is, the video is reduced in data amount by a standard high-efficiency coding method such as MPEG-2, and then synthesized with data such as audio and program information, modulated, and broadcast.
A plurality of signals thus processed are multiplexed and input to the signal input terminal 41. The program information includes codes such as program start date and time, program end date and time, channel, and program name required for reserved recording, as well as program major classification codes representing news, movies, education, political news, economic news, sports. -Sub-category codes representing news, local news, etc., and keywords such as person name, case name, place name, etc. are also included.

The tuner 42 selects a channel according to a control signal from the system control circuit 49 and demodulates a signal. The decoding circuit 43 uses the MPE
Decoding processing such as G-2 is performed and a video signal is output.

The OSD circuit 44 converts the character data from the system control circuit 49 into a character signal synchronized with the video signal, superimposes it on the video signal, or displays it on a blue background, like the OSD circuit 4 in FIG. The characters are displayed and output to the video signal output terminal 54. The encoded video signal is temporarily stored in the buffer memory 47 and then recorded by the disk device 45. The disk control circuit 46 controls the recording / reproducing area of the disk device 45 and the writing / reading of the buffer memory 47.

The information code indicating the recorded contents of the disc is transmitted and received between the disc device 45 and the system control circuit 49 via the disc control circuit 46.
The information code separation circuit 48 separates an information code such as program information from the output signal from the tuner 42 and sends it to the system control circuit 49. Classification code memory 53
Stores codes for politics, economy, sports, etc.,
The data is sent to the system control circuit 4 if necessary.
Send to 9.

The operation unit 50, the program guide memory 51, and the reservation memory 52 perform the same operations as the operation unit 12, the program guide memory 32, and the reservation memory 18 in FIG. 7, respectively.

By the way, the disk device 45 is the tuner 4
2 uses a device capable of recording at a data rate higher than the data rate of the signal output, and the buffer memory 47 is provided when the head is moved to move the recording area (temporary recording becomes impossible at this time). The signal is temporarily stored, and after the head is moved, the read rate (which is equal to the data rate of the signal output by the tuner 42) higher than the write rate of the buffer memory 47 (this is the recording rate to the disk device 45). Read the same and read the data to the disk device 45 to prepare for the next head movement.

The above is the outline of the operation. Next, the operation of the system control circuit 49 of the apparatus shown in FIG. 11 will be described in detail. At the time of recording reservation, the program reservation processing means 491 of the system control circuit 49 uses the classification code memory 5
The data No. 3 is read, the data is converted into a character code, and the character code is sent to the OSD circuit 44 via the recording / playback / display control means 494. The user inputs the priority coefficient KY and the elapsed time coefficient KT for each classification from the operation unit 50 while looking at the classification screen displayed by the OSD circuit 44.

FIG. 12 shows an example of the display screen after the coefficient input. When the major category is news, the minor category indicating the contents of the news program is classified into politics, economy, sports local, religion, and extraordinary minor categories. The priority coefficient KY corresponding to each sub-class is 0.5, 1.0, 0.7, 0.3.
0, 2.0, and the elapsed time coefficient KT is set to 0.2, 0.8, 0.5, 0.1, 0, 1.0, respectively. Here, FIG. 12 is merely an example of the display screen, and it is also possible to devise the display screen so that the user can more intuitively understand it. The reserved recording processing means 491 of the system control circuit 49 is shown in FIG.
The contents of 2 are coded and written in the reserved memory 52. It is also possible to put some or all of the recommended values of the coefficients in the reserved memory 52 in advance so that the user can change only the desired portion.

Next, the recording process will be described by taking a news program as an example. FIG. 13 is a processing flowchart of the system control circuit 49 when recording a video signal on the disk device 45. When "waiting for recording (waiting for recording reservation)" is instructed from the operation unit 50, the process proceeds to step S802 by the interrupt process of step S801. Step S8
In 02, the recording reservation processing means 491 of the system control circuit 49 reads out the program information from the program table memory 51, and retrieves a news program by the above-mentioned major classification code. If there is no news program, the flow advances to step S810 to wait for a new program table to be sent and the program table memory 51 to be updated.

When it is determined in step S802 that there is a news program, in step S803, the program having the earliest start date and time is selected from among the news programs and set as the first recording candidate program. In step S804, it is checked whether there is another news program between the start date and time and the end date and time of the first recording candidate program. If there is a news program whose time overlaps, it is set as the second recording candidate program, and if there are a plurality of news programs, the third candidate, fourth candidate, ... Next, in step S805, the priority order of a plurality of candidates is determined and the recording candidate programs are narrowed down to one. This is done by reading the above-mentioned priority coefficient KY from the reservation memory 52 and comparing the values of the priority coefficient KY according to the small classification code of the recording candidate program. In the example shown in FIG.
When political news, economic news, sports news, or local news is a recording candidate program, the economic news with the highest priority coefficient is selected as a recording candidate program.

Next, in step S806, the recorded content management means 492 causes the recording candidate program start date and time TS.
(R) and the end date / time TE (r), TL (r) is calculated for the duration of the recording candidate program (TL (r) = TE (r) −
Based on TS (r)) and the directory information of the disc sent from the disc control circuit 46, it is determined whether or not a sufficient recording area DZ for recording the recording candidate program is secured. At this time, the disk device 45 of the program (played once) whose reproduction flag (described later) is 1
The upper area is treated the same as the unrecorded area, and these areas are converted into recording time and set as DZ.

If the recording area DZ is large enough to record the recording candidate program, the flow advances to step S815 to select a channel, and then in step S816, the arrival of the recording start time is awaited. If the recording area DZ is not large enough to record the recording candidate program, in step S807, the priorities of all the programs in the directory information are compared, and the numbers (q) are assigned in ascending order of priority. Assign a value. Specifically, the smaller the value of the priority Y calculated by the following equation, the lower the priority.

[0080]

[Equation 1]

Here, TS (d) is the start date / time of each program in the directory information, and TS (r) is the start date / time of the recording candidate program in units of 24 hours. That is, Y, month, day, hour, minute, second
When E, MO, DA, HO, MI, and SE are set, the value of TS is expressed by the following equation.

[0082]

[Equation 2]

Here, a is the number of days in one month,
It is 31 in January and 28 mag in February. Other, end date and time T
E and the like are also represented by similar numerical values. Using the values of FIG. 12, for example, TS (d) is TS
If (r) is today 9:00 pm, TS (d) -TS
(R) = 1, and in the case of political news, Y = 0.
3. In economic news, Y = 0.2.

Next, in step S808, q = 1 is set. Next, in step S809, the priority Y (q) of the q-th program is compared with the priority Y (r) of the recording candidate program. Here, Y (r) is the value of the priority coefficient KY of the recording candidate program itself. If Y (r) is less than or equal to Y (q), it means that the priority of the recording candidate program is lower (or equal) than the lowest priority in the directory information. The recording candidate program is not recorded, and the program guide is waited to be updated (S810).

If Y (r) is larger than Y (q), the flow advances to step S811, and the q-th program at the value of q at this time is set as the first erasure candidate program. And step S
At 812, the duration time TL (q) of the erasure candidate program is added to the recordable time DZ. Here, TL (q) can be obtained by calculating the difference between the end date and time and the start date and time of the deletion candidate program.

In step S813, by comparing the size relationship between the new recordable time DZ and the duration TL (r) of the recording candidate program, it is determined whether or not there is a sufficient recording area when the deletion candidate program is deleted. judge. If the recordable time DZ sufficient for recording the recording candidate program cannot be obtained even if the deletion candidate program is deleted, 1 is added to q in step S814 and the process returns to step S809. The same determination is repeated for. When it is determined in step S813 that the recording area is sufficient during this repetition, the channel is set in step S815, and the process proceeds to step S816.

In step S816, the process waits until the current time data from the date / time generation circuit 56 matches the start date / time TS (r) of the recording candidate program, and if they match, the process proceeds to step S817 to start recording. Recording / playback / reproduction of the system control circuit 49 is performed so that the areas to be recorded are in the order of the unrecorded portion, the program portion having the reproduction flag of 1, the first erasure candidate program portion, the second erasure candidate program portion ,.
A control signal is sent from the display control means 494 to the disk control circuit 46. At the same time, a program information code or the like is sent to the disc control circuit 46 so that the program information of the program recorded in the directory area of the disc and the data of the recording area are recorded. At this time, the reproduction flag of the recorded program is set to 0. In step S818, the data of the current time from the date / time generation circuit 56 is monitored, and if it coincides with the ending date / time TE (r) of the recording candidate program, step S819.
Then, the recording ends.

Next, the reproducing operation of the present invention will be described with reference to FIG. FIG. 14 is a flowchart showing the processing of the system control circuit 49 during reproduction.
When "news play" is instructed from the operation unit 50, the process proceeds to step S902 by the interrupt process of step S901. In step S902, the system control circuit 49 requests the disk control circuit 46 for disk directory information. The disk control circuit 46 reproduces the directory area of the disk in the disk device 45, reads the directory information, and sends it to the system control circuit 49.

In step S903, the system control circuit 49 uses the sent directory information to determine the priority of the recorded program. The priority is the same as in step S807 of FIG.
The value of the number (s) is assigned in descending order of priority. The calculated priority is represented by Y (s).

After setting s = 1 in step S904, it is determined in step S905 whether there is news in the program currently being broadcast. This is because the program code of the program currently being broadcast is temporarily stored in the program code extracting means 495 of the system control circuit 49 from the information code sent from the information code separating circuit 48 while sequentially switching the channels of the tuner 42, and is classified into a large class. This is done by searching for programs whose code is a news code.

In step S906, it is determined whether or not there are a plurality of applicable programs.
Proceed to 7. In step S907, the priority order is determined similarly to step S805 in FIG. 12, and the priority of the highest priority program is set to Y (b).

Then, in step S908, Y
By comparing the values of (s) and Y (b), the priority of the reproduction candidate program and the currently broadcast program are compared.
According to the example of the priority coefficient of FIG. 12, the priority coefficient of the temporary news is set to be the largest, so that Y (b) is always higher when the temporary news is being broadcast. If Y (b) is larger, step S909.
Then, the program channel having the priority of Y (b) is selected, and the changeover switch 55 is set to the R side. Step S91
When the end of the program is determined at 0, the process returns to step S905.

On the other hand, in step S908, Y (s)
If it is larger, the process proceeds to step S911, a control signal is sent to the disc control circuit 46 to reproduce the sth program, and the changeover switch 55 is set to the P side. The disk control circuit 46 searches the disk information for the disk area of the sth program from the directory information, and reproduces that area. When the end of reproduction is detected in step S912, the disk control device 46 stops the disk device in step S913,
Further, in step S914, the disk control circuit 46
The reproduction flag of the sth program is changed to 1 to rewrite the directory information, the reproduction end is sent to the system control circuit 49, and the process returns to step S905. After that,
The processing in the loop shown in FIG. 14 is repeated for the programs having the second, third, ... Priority levels in the disc. However, if another instruction is input from the operation unit 50 on the way, the instruction is followed.

According to the third invention described above, the priority order of the news broadcast in step S805 is determined at the time of recording, and the priority order of the news in the disc is determined in step S807. Accordingly, while the news in the disc is deleted in the order of low priority, the news with the highest priority among the broadcasted news is recorded.
The discs inside will always have high-priority news recorded. Also, at the time of reproduction, step S903.
In, determine the priority of the news in the disc,
Since the playback is performed in the order of the highest priority, the user can view the news in the order from the most desired one.

Furthermore, in step S908, the priority of the news being broadcast is compared even during reproduction, and the channel of the tuner 42 and the changeover switch 55 are selected according to the result, so that the degree of importance is high even during disk reproduction. When a program (for example, extraordinary news) is being broadcast, the program being broadcast can be viewed.

Next, a second embodiment of the third invention will be described. FIG. 15 is a circuit block diagram of a recording / reproducing apparatus with a recording condition judging function showing a second embodiment of the third invention. This recording / reproducing apparatus with a recording condition judging function is characterized in that a keyword memory 60 is added to the recording / reproducing apparatus with a recording condition judging function shown in FIG. 11, and a priority order at the time of recording / reproducing is used by using a keyword. It is something to set. The classification code memory 53 and the keyword memory 60 are shown in FIG.
Unlike the case of 1, a writable memory is used. Others are the same as those of the recording / reproducing apparatus with the recording condition determining function of FIG. The operation will be described below.

The program code extraction means 495 of the system control circuit 49 extracts a keyword from the program information sent from the information code separation circuit 48, in addition to extracting a keyword, and extracts the extracted keyword as a keyword. It is stored in the memory 60. At the time of recording reservation, recording reservation processing means 491 of the system control circuit 49.
Reads a keyword from the keyword memory 60, converts it into a character code, and sends it to the OSD circuit 44. The user looks at the displayed keywords and selects only the necessary keywords. The code of the selected keyword is written in the classification code memory 53. Next, the user
As in the case of 2, the priority coefficient KY and the elapsed time coefficient KT are input from the operation unit 50. After that, the keyword is the third
The same priority is given to the sub-classification in the embodiment of the invention, and the priority order during recording and reproduction is determined.

According to this embodiment, not only is the same effect as the first embodiment of the third invention, but the keyword memory 60 further stores the newly sent keywords, and a part of them is stored. Is written in the classification code memory as the classification code, the priority order can be determined by the keyword in the program information, and it is possible to meet the request to see only specific information such as a person's name, case name, and place name.

[0099]

As described above, according to the present invention, the recording condition determining means determines whether the program to be broadcast is a program of a specific type (for example, news) or not, and the inserted tape is a program of a specific type. Whether or not it is exclusive, the recording area (tape position) of the currently recorded program, the classification code, the classification code of the program being broadcast, etc. are used to determine the priority and set the recording conditions.
