  The storage unit 450 is realized by various IC memories such as ROM and RAM such as flash memory that can be updated and stored, information storage media such as a built-in or data communication terminal, a hard disk, a CD-ROM, and a reading device thereof. The program and data for realizing various functions as a server computer system such as a system program, and the program and data necessary for causing the CPU 410 to control the entire broadcast content transmission system 30 are stored. In particular, in order to realize the first embodiment, a guide broadcast management program 451, a broadcast content providing program 452, a voice recognition processing program 453, a guide broadcast table 454, and a broadcast section specifying table 456 are stored.

  The guide broadcast management program 451 is a program for generating guide broadcast data based on the guide broadcast sound input from the guide broadcast system 10 and managing it as a guide broadcast table 454. The CPU 410 is a guide broadcast management program 451. The guidance broadcast management process is performed according to

  The broadcast content provision program 452 is a program for performing control to generate broadcast content data and transmit it to the user terminal 70a when a broadcast content provision request is notified from the user terminal 70a. A first guide broadcast extraction program 452a for extracting guide broadcast data 455 (see FIG. 4) from the guide broadcast table 454 according to the current position data notified together with the content provision request is included. The CPU 410 performs broadcast content provision processing according to the broadcast content provision program 452.

  The voice recognition processing program 453 performs voice recognition (phoneme analysis) on the guidance broadcast voice input from the guidance broadcast system 10 to convert it into text data, and analyzes the semantic content by morphological analysis, syntax analysis, semantic analysis, and the like. This is a program for extracting keywords, and the CPU 410 executes voice recognition processing according to the voice recognition processing program 453. Note that detailed speech analysis and semantic analysis are appropriately implemented using known techniques, and the description thereof is omitted here.

  The guide broadcast table 454 stores and stores guide broadcast data 455 generated based on the guide broadcast sound broadcast by the guide broadcast system 10. FIG. 4 is a diagram illustrating a data configuration example of the guidance broadcast table 454. As shown in FIG. 4, the guide broadcast table 454 includes a guide in which a guide broadcast sound 455a, an output broadcast system ID 455b, a broadcast time 455c, a guide broadcast text 455d, a keyword 455e, and a broadcast ID 455f are associated with each other. Broadcast data 455 (455-1, 2, 3,...) Is accumulated.

In the output broadcast system ID 455b, the broadcast system ID of the guide broadcast system 10 that has transmitted the guide broadcast sound 455a is set.
At the broadcast time 455c, when the guidance broadcast sound 455a is broadcast by the guidance broadcast system 10 and transmitted to the guidance broadcast management server 40a (broadcast start time), and when the broadcast is finished and transmitted. Is set (broadcast end time).
In the guidance broadcast text 455d, text data converted as a result of voice recognition processing for the guidance broadcast voice 455a is set.
In the keyword 455e, a keyword extracted as a result of semantic analysis for the guidance broadcast sound 455a is set.
The broadcast ID 455f is ID information for identifying the guide broadcast sound 455a, and is assigned when the guide broadcast data 455 is generated.

  In the guide broadcast management process, the CPU 410 generates guide broadcast data 455 when a guide broadcast sound is input from the guide broadcast system 10 and manages it as the guide broadcast table 454. At this time, the guide broadcast data ID 455b is used as the guide broadcast data 455b. With reference to the guide broadcast data 455 in which the broadcast system ID of the guide broadcast system 10 that broadcasts the broadcast audio is set, the keyword 455e is checked to search for the update target guide broadcast data 455. If the guide broadcast data 455 to be updated is retrieved, the CPU 410 overwrites the guide broadcast data to be updated and updates the guide broadcast table 454.

  As a specific example, for example, when keywords “XX line”, “10 minutes”, “delay”, and “during driving” are set as the keywords 455e of the newly generated guidance broadcast data, the guidance shown in FIG. The broadcast data 455-1 is searched as an update target, and the guide broadcast data 455 based on the guide broadcast sound that guides the delay time “15 minutes” is the latest broadcast status guide broadcast sound that guides the delay time “10 minutes”. Overwritten with guidance broadcast data based on When the keyword extracted from the newly generated guidance broadcast data matches the keyword 455e of the guidance broadcast data 455 stored in the guidance broadcast table 454, the guidance broadcast data 455 is newly generated. It is overwritten by the guidance broadcast data.

  On the other hand, when there is no guide broadcast data to be updated, the CPU 410 adds the generated guide broadcast data 455 and updates the guide broadcast table 454. In addition, the CPU 410 updates the guide broadcast table 454 by deleting the guide broadcast data 455 after a predetermined time has elapsed from the broadcast time 455c.

  The broadcast section specifying table 456 stores the correspondence relationship between the broadcast sections and the base stations 50 in the broadcast sections. FIG. 5 is a diagram showing a data configuration example of the broadcast segment specifying table 456. In this broadcast section specifying table 456, a broadcast system ID assigned to each guidance broadcasting system 10 in the station premises is set as a broadcast section, and a base station installed in the broadcast section in association with the broadcast system ID. 50 base station IDs are set.

  When the broadcast content provision request is notified from the user terminal 70a in the first guidance broadcast extraction process, the CPU 410 refers to the broadcast segment specifying table 456, and determines the base station ID notified together with the broadcast content provision request. Originally, the broadcast section where the user terminal 70a is located is specified and detected.

(User terminal)
FIG. 6 is a block diagram illustrating an example of a functional configuration of the user terminal 70a according to the first embodiment. As illustrated in FIG. 6, the user terminal 70 a includes a CPU 710, an input unit 720, a display unit 730, a transmission / reception unit 740, a wireless communication unit 750, and a storage unit 760.

  The CPU 710 is based on programs and data stored in the storage unit 760, data transmitted from the base station 50 connected to the user terminal 70a via the wireless communication unit 750, operation signals input from the input unit 720, and the like. The user terminal 70a is generally controlled by giving instructions to each functional unit constituting the user terminal 70a, transferring data, and the like.

  The input unit 720 is realized by a button switch or the like to which various functions are assigned, and outputs an operation signal corresponding to the operation input to the CPU 710.

  The display unit 730 is realized by a display device such as an LCD (Liquid Crystal Display) or an ELD (Electronic Luminescent Display), and displays various screens based on display signals input from the CPU 710.

  The transmitter / receiver unit 740 is for inputting a transmitted voice and outputting a received voice, a ringtone, and the like, and is configured by a microphone, a speaker, and the like.

  The wireless communication unit 750 is connected to the base station 50 and performs data communication with the guide broadcast management server 40a, and is realized by an antenna, an RF converter, or the like that transmits and receives wireless signals.

  The storage unit 760 is realized by various IC memories such as ROM and RAM such as flash memory that can be updated and stored, and stores various programs related to the operation of the user terminal 70a and data such as processing results by the programs. Is done. In particular, in order to realize the first embodiment, a first broadcast content output program 761, current position data 762, and a received broadcast ID 763 are stored.

  When the first broadcast content output program 761 enters the communication area of the base station 50 and communication with the base station 50 is established, the first broadcast content output program 761 notifies the guidance broadcast management server 40a of the broadcast content provision request and responds thereto. The CPU 710 performs a first broadcast content output process in accordance with the first broadcast content output program 761.

Specifically, when the broadcast content provision request is transmitted to the guidance broadcast management server 40a, the CPU 710 acquires the base station ID when communication with the base station 50 is established, and the acquired base station ID is When the base station ID is different from the previously acquired base station ID, a broadcast content provision request is notified to the guide broadcast management server 40a together with the current position data 762. In addition, even if the acquired base station ID and the previously acquired base station ID are the same, the CPU 710 issues a broadcast content provision request together with the current position data 762 when a predetermined broadcast content output operation is performed. The information is notified to the guidance broadcast management server 40a.
And CPU710 performs control which displays this, if broadcast content data are received from the guidance broadcast management server 40a.

  The current position data 762 is information for specifying the current position of the user terminal 70a, and the base station ID 762a acquired from the base station 50 with which communication has been established, and the communication establishment time when the communication has been established. 762b is included. The current position data 762 is updated every time communication between the user terminal 70a and the base station 50 is established.

  The received broadcast ID 763 stores a list of broadcast IDs set in the broadcast content data received in the past. When broadcast content data is received from the guide broadcast management server 40a, the broadcast ID set in the received broadcast content data is added to the received broadcast ID 763.

[Process flow]
Next, with reference to FIGS. 7-9, the flow of processing of the guidance broadcast management server 40a and the user terminal 70a in the first embodiment will be described.

  First, the flow of the guidance broadcast management process in the guidance broadcast management server 40a will be described with reference to the flowchart shown in FIG. Note that the processing described here is realized by the CPU 410 reading and executing the guidance broadcast management program 451.

  In the guidance broadcast management process, when a guidance broadcast voice is input from the guidance broadcast system 10 (step a10: YES), the CPU 410 first executes a voice recognition process (step a20). In this voice recognition process, the CPU 410 recognizes the guidance broadcast voice and converts it into text data (step a21), then analyzes the semantic content of the converted text data and extracts keywords (step a23). Based on the result of the voice recognition processing, the CPU 410 generates guidance broadcast data (step a30).

  Subsequently, the CPU 410 searches the guide broadcast table 454 for the update target guide broadcast data 455 based on the guide broadcast data output broadcast system ID 455b and the keyword 455e generated in step a30 (step a40). If the update target guide broadcast data 455 is searched (step a50: YES), the CPU 410 updates the guide broadcast table 454 by overwriting the update target guide broadcast data (step a60). According to this, if there is guide broadcast data 455 having contents similar to the newly generated guide broadcast data, the guide broadcast data 455 is overwritten with the newly generated guide broadcast data, so that it is the same as the guide broadcast table 454. It is possible to prevent duplicate content guide broadcast data from being stored. On the other hand, when the guide broadcast data to be updated is not searched (step a50: NO), the CPU 410 adds the generated guide broadcast data and updates the guide broadcast table 454 (step a70).

  Subsequently, the CPU 410 compares the broadcast time 455c with the current time, deletes the guide broadcast data after a predetermined time (for example, 10 minutes) has elapsed from the broadcast time 455c, and updates the guide broadcast table 454 (step a80). Then, the CPU 410 returns to step a10 and waits until a new guidance broadcast sound is input. If the guidance broadcast sound is input, the CPU 410 executes the processing described above.

  Next, the flow of the first broadcast content output process in the user terminal 70a and the flow of the broadcast content provision process in the guidance broadcast management server 40a will be described with reference to the flowchart shown in FIG. In the process described here, the CPU 710 reads and executes the first broadcast content output program 761 in the user terminal 70a, and the broadcast content providing program including the first guide broadcast extraction program 452a in the guide broadcast management server 40a. This is realized by reading and executing 452.

  In the first broadcast content output process, the CPU 710 of the user terminal 70a obtains a base station ID from the base station 50 when communication between the user terminal 70a and the base station 50 is established (step b10: YES). (Step b20). Then, the CPU 710 compares the acquired base station ID with the base station ID 762a (that is, the previously acquired base station ID) to determine whether or not they are the same, and the acquired base station ID is the previous acquired base station. If they are different (step b30: NO), the process proceeds to step b50. At this time, the CPU 710 updates the current position data 762 based on the acquired base station ID and the current time.

  On the other hand, if the acquired base station ID is the same as the previously acquired base station (step b30: YES), the CPU 710 accepts a predetermined broadcast content output operation and if the broadcast content output operation is performed (step b30). b40: YES), the process proceeds to step b50. At this time, the CPU 710 updates the communication establishment time 762b with the current time.

  In step b50, the CPU 710 transmits a broadcast content provision request together with the current position data 762 to the guidance broadcast management server 40a.

  In response to this, the broadcast content providing process is executed in the guide broadcast management server 40a. That is, when the CPU 410 receives the broadcast content provision request (step c10: YES), the CPU 410 executes the first guidance broadcast extraction process according to the first guidance broadcast extraction program 452a (step c20). FIG. 9 is a flowchart for explaining the flow of the first guidance broadcast extraction process.

  In the first guidance broadcast extraction process, the CPU 410 first refers to the broadcast segment identification table 456 and identifies the broadcast segment where the user terminal 70a is located based on the base station ID notified together with the broadcast content provision request. (Step d10).

  Next, the CPU 410 refers to the guide broadcast table 454, extracts guide broadcast data 455 in which the broadcast system ID of the broadcast section detected in step d10 is set as the output broadcast system ID 455b (step d30), and performs this process. finish.

  Returning to FIG. 8, the CPU 410 performs control to transmit the broadcast ID 455f set in the guide broadcast data 455 extracted as a result of the first guide broadcast extraction process to the user terminal 70a (step c21).

  In the user terminal 70a, when receiving the broadcast ID (step b51: YES), the CPU 710 checks the received broadcast ID 763 to determine whether or not the received broadcast ID is set. If set, the CPU 710 determines that the broadcast ID has been received (step b52: YES), and sets the received flag to “ON” (step b53). On the other hand, in the case of the broadcast ID received for the first time (step b52: NO), the CPU 710 sets the received flag to “OFF” (step b54).

  And CPU710 performs control which transmits the information of the received flag set by step b53 or step b54 to the guidance broadcast management server 40a (step b55). If the transmitted received flag is “OFF” (step b56: YES), the CPU 710 goes to step b60 and is in a standby state until it receives broadcast content data.

  In the guidance broadcast management server 40a, when the CPU 410 receives the received flag (step c22: YES), the CPU 410 determines the received flag, and when “OFF” is set (step c23: YES), Control goes to step c30. That is, the CPU 410 generates broadcast content data by associating the output broadcast system ID 455b, the guide broadcast text 455d, and the broadcast ID 455f set in the guide broadcast data 455 extracted as a result of the first guide broadcast extraction process in step c20. (Step c30), control is performed to transmit the generated broadcast content data to the user terminal 70a (Step c40).

  In the user terminal 70a, if the broadcast content data is received (step b60: YES), the CPU 710 displays the received broadcast content data on the display unit 730 (step b70). At this time, the CPU 710 updates the received broadcast ID 763 by adding the broadcast ID set in the received broadcast content data to the received broadcast ID 763 (step b75).

  Then, for example, if a predetermined end operation has been performed (step b80: YES), the CPU 710 ends the present process.

  As described above, according to the first embodiment, the content of the guidance broadcast broadcast in the broadcast section where the user terminal 70a is located can be provided to the user terminal 70a. Further, the content of the guidance broadcast can be provided in response to a request from the user terminal 70a. Therefore, the contents of the volatile guidance broadcast broadcast by the guidance broadcast system 10 can be stored and appropriately provided to the user terminal 70a.

FIG. 10 is a block diagram illustrating an example of a functional configuration of the guidance broadcast management server 40b according to the second embodiment. The guide broadcast management server 40b includes a CPU 410, an input unit 420, a display unit 430, a communication unit 440, an external input unit 470, and a storage unit 460.

  In the second embodiment, the storage unit 460 stores a guide broadcast management program 451, a guide broadcast distribution program 462, a voice recognition processing program 453, and a guide broadcast table 454.

  The guidance broadcast distribution program 462 is a program for transmitting the guidance broadcast table 454 to the user terminal 70b when a guidance broadcast provision request is notified from the user terminal 70b. In accordance with 462, guidance broadcast distribution processing is performed.

(User terminal)
FIG. 11 is a block diagram illustrating an example of a functional configuration of the user terminal 70b in the second embodiment. As illustrated in FIG. 11, the user terminal 70 b includes a CPU 710, an input unit 720, a display unit 730, a transmission / reception unit 740, a wireless communication unit 750, and a storage unit 770.

  In the second embodiment, the storage unit 770 includes a second broadcast content output program 771, a broadcast segment specifying table 772, current position data 762 including a base station ID 762a and communication establishment time 762b, and movement schedule information 773. , Output format setting information 774 and reception guidance broadcast table 775 are stored.

  When communication with the base station 50 is established, the second broadcast content output program 771 notifies the guide broadcast management server 40b of a guide broadcast provision request, and is transmitted from the guide broadcast management server 40b in response thereto. A program for outputting broadcast content data based on the guidance broadcast table (reception guidance broadcast table 775), and a second program for extracting the guidance broadcast data from the reception guidance broadcast table 775 according to the current position data 762. A guidance broadcast extraction program 771a is included. The CPU 710 performs a second broadcast content output process according to the second broadcast content output program 771.

  The broadcast zone specifying table 772 stores the correspondence between the broadcast zone and the base station 50 in the broadcast zone. This broadcast segment specifying table 772 is a data table similar to the broadcast segment specifying table 456 (see FIG. 5) stored in the storage unit 450 of the guide broadcast management server 40a in the first embodiment. In the two-guide broadcast extraction process, the broadcast section specifying table 772 is referred to, and the broadcast section where the user terminal 70b is located is specified and detected based on the base station ID 762a.

  The movement schedule information 773 stores movement data such as a preset connecting journey of a user's train. The movement schedule information 773 is created in advance based on an operation input or the like. FIG. 12 is a diagram illustrating a data configuration example of the movement schedule information 773. As shown in FIG. 12, in the movement schedule information 773, for each route to be connected, the boarding station, the departure time from the boarding station, the boarding information set with the departure number line, the getting-off station, the arrival at the getting-off station The moving data in which the time and the getting-off information in which the arrival number line is set are stored. In addition, in this movement schedule information 773, in addition to data related to the route to be transferred, data related to a meeting place where a waiting room or the like stops may be set.

  The CPU 710 refers to the movement schedule information 773 in the second guidance broadcast extraction process, selects a broadcast section including the user's destination based on the current position data 762, and the broadcast section where the user terminal 70b is located. The guide broadcast data in which the broadcast system ID assigned to the guide broadcast system 10 is set and the guide broadcast data in which the broadcast system ID of the selected destination broadcast section is set are extracted from the reception guide broadcast table 775.

  As a specific example, for example, it is assumed that the current time is “2005/06/21 14:09” and the user is at “EE station”. In this case, the CPU 710 checks the boarding information and searches for movement data relating to movement at “EE station” and movement data relating to movement after the current time (record L21). Then, the CPU 710 selects a destination broadcast section based on the departure number line “No. 2 home”. As a result, the contents of the guidance broadcast broadcast on “No. 2 home” which is the broadcast section of the movement destination are output.

The output format setting information 774 is setting information for determining whether to display or output the contents of the guidance broadcast. Either one of the “text display” and “audio output” output formats is set by the user operation. Switched and set.
In the second broadcast content output process, the CPU 710 generates broadcast content data based on the guide broadcast data extracted as a result of the second guide broadcast extraction process. At this time, “text display” is displayed in the output format setting information 774. If set, broadcast content data in which the output broadcast system ID is associated with the guidance broadcast text is generated. On the other hand, if “audio output” is set in the output format setting information 774, the CPU 710 generates broadcast content data in which the output broadcast system ID is associated with the guidance broadcast audio.

  The reception guide broadcast table 775 is a guide broadcast table transmitted from the guide broadcast management server 40b in response to a guide broadcast provision request.

[Process flow]
Next, the flow of the second broadcast content output process in the user terminal 70b and the flow of the guide broadcast distribution process in the guide broadcast management server 40b will be described with reference to the flowchart shown in FIG. In the process described here, the CPU 710 reads and executes the second broadcast content output program 771 including the second guide broadcast extraction program 771a in the user terminal 70b, and the CPU 410 executes the guide broadcast distribution program in the guide broadcast management server 40b. This is realized by reading and executing 462.

  In the second broadcast content output process, the CPU 710 of the user terminal 70b acquires the base station ID from the base station 50 when communication between the user terminal 70b and the base station 50 is established (step e10: YES). (Step e20). Then, the CPU 710 compares the acquired base station ID and the base station ID 762a (that is, the previously acquired base station ID) to determine whether or not they are the same, and the acquired base station ID and the previously acquired base station are the same. If they are different (step e30: NO), the process proceeds to step e40. At this time, the CPU 710 updates the current position data 762 based on the acquired base station ID and the current time.

  In step e40, the CPU 710 transmits a guide broadcast provision request together with the current position data 762 to the guide broadcast management server 40b.

  In response to this, the guidance broadcast management server 40b executes guidance broadcast distribution processing. That is, when receiving the guidance broadcast provision request (step f10: YES), the CPU 410 reads the guidance broadcast table 454 from the storage unit 460 and transmits it to the user terminal 70b (step f20).

  In the user terminal 70b, if the guidance broadcast table is received (step e50: YES), the CPU 710 executes a second guidance broadcast extraction process (step e60). FIG. 14 is a flowchart for explaining the flow of the second guidance broadcast extraction process.

  In the second guidance broadcast extraction process, the CPU 710 first refers to the broadcast section specifying table 772 and specifies and detects the broadcast section where the user terminal 70b is located based on the base station ID 762a (step g10). Subsequently, the CPU 710 refers to the movement schedule information 773, and selects a broadcast zone to which the user is moving based on the current time (step g20).

  Then, the CPU 710 refers to the reception guide broadcast table 775 and extracts the guide broadcast data in which the broadcast system ID of the broadcast section identified in step g10 and the destination broadcast section selected in step g20 is set as the output broadcast system ID. (Step g30), and this process is terminated.

  Returning to FIG. 13, when the second guidance broadcast extraction process is completed, the CPU 710 refers to the output format setting information 774 to determine the output format (step e <b> 70). If the output format is “text display”, CPU 710 generates broadcast content data by associating the output broadcast system ID set in the guide broadcast data extracted in step e60 with the guide broadcast text (step e80). The guide broadcast text is displayed on the display unit 730 according to the generated broadcast content data (step e90).

  On the other hand, if the output format is “audio output”, CPU 710 generates broadcast audio data by associating the output broadcast system ID set in the guide broadcast data extracted in step e60 with the guide broadcast audio (step e100). According to the generated broadcast content data, the guidance broadcast sound is output from the speaker of the transmission / reception unit 740 (step e110).

  For example, if a predetermined end operation is performed (step e120: YES), the CPU 710 ends the present process.

  As described above, according to the second embodiment, the content of the guidance broadcast broadcast by the guidance broadcast system 10 can be transmitted to the user terminal 70b. Then, in the user terminal 70b, the content of the guidance broadcast broadcast in the broadcast section where the user terminal 70b is located, and the guidance broadcast broadcast in the broadcast section where the user carrying the user terminal 70b moves. Can be output. Therefore, the content of the volatile guidance broadcast broadcast by the guidance broadcast system 10 can be appropriately provided to the user of the user terminal 70b.

  In addition, when the output format of the content of the guidance broadcast is switched in accordance with a user operation and the content of the guidance broadcast is output, display output or sound output can be performed according to the designated output format.

[Modification]
The preferred embodiments of the present invention have been described above, but the present invention is not limited to those described above, and can be changed as appropriate without departing from the spirit of the invention.

  For example, in the first embodiment described above, the guide broadcast management server 40a extracts guide broadcast data in which the broadcast system ID of the broadcast section in which the user terminal 70a is located is extracted, and the broadcast content is based on the extracted guide broadcast data. Although data is generated and transmitted to the user terminal 70a, it may be as follows.

  That is, in the user terminal 70a, the movement schedule information and the output format setting information described in the second embodiment are created and stored according to the user operation. If the communication with the base station 50 is established, the user terminal 70a notifies the guidance broadcast management server 40a of the broadcast content provision request. At this time, in addition to the current position data, the movement schedule information and the output format setting Information is notified to the guidance broadcast management server 40a.

  On the other hand, the guidance broadcast management server 40a selects a broadcast section including the destination based on the current position data and the movement schedule information notified together with the broadcast content provision request, and the broadcasting system of the selected destination broadcast section is selected. Guide broadcast data set with an ID is extracted.

  Then, the guidance broadcast management server 40a follows the output format setting information notified together with the broadcast content provision request, and if “text display” is set, the output broadcast system ID and guidance set in the extracted guidance broadcast data. Broadcast content data associated with broadcast text is generated. The guidance broadcast management server 40a also broadcast content data in which the output broadcast system ID set in the extracted guidance broadcast data is associated with the guidance broadcast audio if “audio output” is set in the output format setting information. Is generated. Then, the guide broadcast management server 40a transmits the generated broadcast content data to the user terminal 70a that has notified the broadcast content provision request.

  As a result, it is possible to extract the contents of the guidance broadcast broadcast in the broadcast section of the user's destination and provide it to the user terminal 70a. At this time, it is possible to generate broadcast content data for outputting the content of the guidance broadcast to be provided in the output format designated by the user operation, and transmit it to the user terminal 70a.

  Further, in this case, when the guidance broadcast sound is input from the guidance broadcast system 10, the guidance broadcast management server 40 a determines the effective time range of the guidance broadcast audio, and further associates the determined effective time range. The set guidance broadcast data may be generated.

  In this case, the guidance broadcast management server 40a prepares a table that defines the travel time between broadcast sections. Then, when the broadcast content provision request is notified from the user terminal 70a, the guidance broadcast management server 40a, based on the current position data and the movement schedule information notified together with the broadcast content provision request, the user terminal 70a. The travel time from the broadcast section where the mobile station is located to the broadcast section including the destination is read, and the arrival time at the transmission target section is predicted based on the communication establishment time of the current position data and the read travel time. The guidance broadcast management server 40a checks the valid time range set in the extracted guidance broadcast data, generates broadcast content data based on the guidance broadcast data whose predicted arrival time does not exceed the valid time range, and uses it. To transmit to the user terminal 70a.

  Here, a specific example will be described with reference to FIG. 15, taking as an example a case where a user who arrives at the broadcast section “Underground A exit ticket gate concourse” moves to “underground platform”. In FIG. 15, the horizontal axis indicates time (t), and the effective time range “13:15” to “13:45” of the broadcast h broadcast on “underground home” is illustrated. Here, for example, it is assumed that the travel time between the broadcast section “underground platform” and the broadcast section “underground A exit ticket gate concourse” is “10 minutes”.

  In this case, whether or not the arrival time exceeds the valid time range is determined based on the valid time range “13:15” to “13:45” and the travel time “10 minutes”. For example, the arrival time of the user H arriving at the “underground A exit ticket gate concourse” at “13:30” is predicted to be “13:40” and does not exceed the valid time range. The contents of the broadcast h are provided to the user terminal 70a carried by the user H. On the other hand, the arrival time of the user I who arrived at the “underground A exit ticket concourse” at “13:40” is predicted to be “13:50” and exceeds the valid time range. The contents of the broadcast h are not provided to the user terminal 70a carried by the user I. That is, among the users who use the “underground platform” as the destination broadcast zone, users who have arrived at the “concourse outside the underground ticket gate A entrance” between “13:15” and “13:35” The content of the broadcast h is provided to the terminal 70a.

  Moreover, it is good also as determining the effective time range of guidance broadcast audio | voice according to timetable information, such as a normal timetable and a driving arrangement plan (recovery timetable). For example, “14:00” is set as the effective time range of the guidance broadcast related to the operation of the train whose departure time is “14:00”. If “14:00” is passed, the data of the guide broadcast is deleted from the guide broadcast table 454.

  In the second embodiment described above, the guidance broadcast management server 40b determines the effective time range of the guidance broadcast audio when the guidance broadcast audio is input from the guidance broadcast system 10, and the determined effective time range is determined. Further, guidance broadcast data set in association with each other may be generated.

  In this case, in the user terminal 70b, a transmission target section specifying table in which the correspondence between the broadcast section and the transmission target section is set, and a table that defines the movement time between the broadcast sections are prepared. Then, in the user terminal 70b, the travel time from the broadcast section where the user terminal 70b is located to the transmission target section for the broadcast section is read, and based on the communication establishment time 762b of the current position data 762 and the read travel time. Thus, the arrival time to the transmission target section is predicted. Then, the user terminal 70b checks the valid time range set in the extracted guidance broadcast data, generates broadcast content data based on the guidance broadcast data whose predicted arrival time does not exceed the valid time range, and generates the broadcast content data. Broadcast content data is output.

  Also, a broadcast content transmission system may be constructed for each broadcast section within the station. FIG. 16 is a diagram for explaining the configuration of the entire system in this case. As shown in FIG. 16, a guide broadcast management server 40 c may be installed in each broadcast section such as “Concourse in the central gate ticket gate” or “No. 1 home”. In this case, the guidance broadcast management server 40c is connected to the base station 50 via the network N10 to constitute the broadcast content transmission system 30c, and the guidance broadcast for performing the guidance broadcast toward the corresponding broadcast section. In addition to being connected to the system 10, it is connected to a user terminal 70 located in the broadcast section via the base station 50. And the guidance broadcast management server 40c provides the content of the guidance broadcast broadcast in the said broadcast division with respect to the user terminal 70 located in a corresponding broadcast division.

  In the above embodiment, the guide broadcast management server 40 specifies the broadcast section where the user terminal 70 is located by the base station ID, but may be as follows. That is, the user terminal 70 is configured to include a GPS antenna or the like that receives radio waves from a GPS (Global Positioning System) satellite. Then, the absolute position (latitude, longitude, etc.) is measured from the radio wave received by the GPS antenna, and the broadcast content provision request is notified to the guide broadcast management server 40 together with the measured absolute position. In this case, the guidance broadcast management server 40 manages the correspondence relationship between the broadcast section and the absolute position of the broadcast section, and the broadcast section where the user terminal 70 is located by the absolute position notified together with the broadcast content provision request. Is identified.

  In this case, an IC tag storing data related to the location is arranged in advance at a predetermined position in a station such as a ticket gate or a platform, or in a predetermined position in a vehicle such as an entrance / exit or a seat. On the other hand, the user terminal 70 is configured to include a tag reading device for communicating with the aforementioned IC tag. Then, the user terminal 70 performs short-range wireless communication with the IC tag and reads the data related to the arrangement location stored in the IC tag, thereby correcting the absolute position measured by the GPS function. Good.

  In the second embodiment described above, the guidance broadcast management server 40b refers to the movement schedule information 773 and selects the broadcast section of the user's destination, but the user carries it with an electronic ticket service or the like. Broadcast sections may be selected based on ticket information issued to the user terminal 70b. In this case, the user terminal 70b manages the ticket information described above, and notifies the guidance broadcast management server 40b of a broadcast content provision request together with the ticket information. The guidance broadcast management server 40b selects a broadcast section including the user's destination based on the ticket information notified together with the broadcast content provision request.

  At this time, the type may be determined from the ticket information notified together with the broadcast content provision request, and the broadcast section may be selected according to the determined type of ticket. According to this, for example, when ticket information including an express ticket for the Shinkansen is notified, the content of the guidance broadcast broadcast by the guidance broadcasting system 10 having the Shinkansen home as a broadcasting section is sent to the user terminal 70b. It can be provided.

  In the above-described embodiment, when the newly generated guidance broadcast data is similar to the previously generated guidance broadcast data 455, it is overwritten with the new guidance broadcast data. It may be. For example, assuming that broadcast content is provided to a hearing-impaired person, providing the content of the new broadcast even if the content of the new broadcast is similar to the content of the past broadcast It is good. A hearing-impaired person cannot determine that there was a broadcast even if he / she was there when the broadcast was broadcast. Therefore, consider sending in real time when the broadcast flows. After the process of step a30 described in FIG. 7, the generated guide broadcast data is transmitted to all user terminals 70 located in the broadcast section. On the other hand, on the user terminal side, when the hearing impairment mode is set by a user operation, the received guidance broadcast data is displayed and output.

  In the embodiment described above, it is determined whether or not the newly generated guidance broadcast data is similar to the previously generated guidance broadcast data 455 depending on whether or not the extracted keywords match. Similarity may be determined using an existing method such as matching based on syntax analysis information of text data converted as a result of speech recognition of broadcast speech.

  The broadcast content transmission system of the present invention is not limited to use in railway facilities, but provides broadcast guidance for an unspecified number of users such as department stores, event venues, amusement facilities, and public facilities. If it is a place, it is applicable similarly.

For example, when it is applied to a department store, it may be applied to guidance broadcasts related to time services and events that have an effective time range during the event period, or to informational broadcasts that change the sales floor within the effective time range until the closing time. it can. Therefore, the content of the guidance broadcast can be appropriately provided to the user, and the same content need not be broadcast many times.
In addition, when applied to amusement facilities, temporary attractions that are valid for the duration of the event, guidance broadcasts related to the location of the event, and waiting for individual attractions that are valid for the time until the closing time It can be applied to guidance broadcasts such as changes in time and operating hours, and guidance broadcasts related to admission restrictions and suspension of operations.
In addition, when applied to public facilities, it can be applied to lost or lost information guidance broadcasts in which the time until the parent or owner is found is valid.
In addition, when applied to highways, mountain trails, etc., it can be applied to broadcasts that give warnings such as falling rocks and footholds, and information on weather.

  It can also be used when broadcasting business is taken over. In other words, by providing the person in charge who takes over the broadcasting business with the contents of the broadcast conducted by the previous person in charge, the broadcast contents of the previous person in charge can be confirmed, and the takeover can be performed smoothly.
