Based on this, the program guide screen generation / display unit 29 generates and displays a program guide screen.

The program guide screen generation / display unit 29 is a CGI (Com
monGatewayInterface) and other HTML automatic generation programs /
Implemented by script. The contents of the processing are as follows: all the program information files stored in a predetermined directory of the storage device 6 are read from the storage device 6 of the information transmission device 200 in accordance with the process of step S3 in FIG. , Program attribute information such as a start time, an end time, and a program title, and lays out and displays these data. Specifically, a description file (HTML file) of a program table screen as shown in FIG. ) Is automatically generated.

In the process of generating the program guide screen, the programs for which the broadcasting has been completed may be excluded, and only the programs that are being broadcast or the broadcasting has not started yet may be displayed. This can be done by identifying the program information files for the end of the broadcast from the program ID part of the file name and not reading these files.

Next, the operation of program distribution according to the registered program schedule will be described. FIG. 9 is a diagram illustrating a description example of channel information stored in the storage device 6 of the information transmitting device 200. As the channel information, the video input device 21 assigned to each channel number,
Information such as a multicast address and a port number is stored, and is used to obtain a correspondence between a distribution channel number designated at the time of program registration, a video input unit 21 used at the time of actual program distribution, and a multicast address / port number. Things. The channel information is created in advance before the system operation starts. Here, the file is created as one file per channel. In this example,
Channel 3 information is defined. The file name may be named “3ch.txt” including the channel number so that the channel number can be identified.

FIG. 10 is a flowchart showing an operation procedure of distribution scheduling section 31 of information transmitting apparatus 200. Hereinafter, the operation of the distribution scheduling unit 31 will be described with reference to FIG. Delivery scheduling unit 3

First, the program guide information input unit 28 periodically checks a predetermined directory of the storage device 6 in which the program information file is stored, and checks whether a newly generated program information file exists (step S11). . It is checked whether there is newly registered program information (step S12). If there is no newly registered program information file, the process returns to step S11 and repeats the same process again. On the other hand, if there is a newly registered program information file, the newly read program information file is read out, the channel number, the start time, and the end time are obtained and stored in the storage device 6 (step S13). .

Next, the channel information file of the channel corresponding to the obtained channel number is read, and the identification information, the multicast address and the port number of the video input unit 21 assigned to the channel are obtained, and these information are obtained. Store in the storage device 6 (step S
14).

Subsequently, the program broadcast time A is calculated from the start time and the end time obtained in step S13 (step S15). Further, the current time is obtained, a time B until the start time is calculated, a time D obtained by subtracting the time C required for the distribution preparation process from B is obtained, and the time D is waited.
(Step S16).

Next, when the wait is completed, the video transmission unit 22
Then, a request is sent to transmit the identification information, the multicast address, and the port number information of the video input unit 21 stored in step S13 only during the program broadcast time A obtained in step S14 (step S17).

Upon receiving the transmission request from the distribution scheduling unit 31, the video transmission unit 22 converts the input stream of the specified channel from the video input unit 21 into the designated program broadcast time A during the designated program broadcast time A. A process of transmitting the multicast address and port number is performed, and a result of the start process is returned (step S18). Here, the input stream indicates video information or the like output from the video input unit 21.

Next, it waits for a response from the video transmission unit 22, and confirms success or failure of the program distribution start later according to the response content (step S19). In addition, it is necessary to prepare to be able to output the input video from the connected video input device 1 to the video transmission unit 22 via the video input unit 21 used for program distribution before the start of program broadcasting. . From the start time, the lecturer performs an operation such as starting a lecture in front of the camera of the video input unit 1.

Next, the student searches the program table screen shown in FIG. 7 for the program currently being broadcast, and if there is a program to be viewed from among the currently broadcast programs, clicks on the program name to display the program name in FIG. A program viewing screen as shown is displayed, and the program can be viewed.

As described above, the program viewing screen shown in FIG. 8 is created by selecting a program name from the program guide screen shown in FIG.
0, which is executed according to the processing procedure shown in FIG.

Next, the program viewing process will be described with reference to the flowchart shown in FIG. First, when a program name is selected and clicked from the program guide screen of FIG. 7, the program screen generation unit 30 specifies the program information file of the program, reads out the specified program information file, and describes the specified program information file. Acquire various program attribute information (step S
21).

Next, the current time is acquired and compared with the broadcast date / start time in the acquired attribute information to check whether the program has been completed (step S22). This process is unnecessary when the program table is created so as not to display the finished program. Also, if the program has ended,
Since the program has already ended and cannot be attended, the attendee is notified by displaying a dialog such as "Program ended" or the like, and the subsequent reproduction process is not performed.

On the other hand, if the program is not completed, the requesting terminal is the information transmitting device 200 or the information receiving device 500.
Is identified, a program screen for the instructor or the learner is created, and displayed on the Web browser of the information receiving apparatus 500 (step S23), and the displayed program is reproduced (step S23). Step S24). In each of the program screens, as in the screen layout shown in FIG. 8, the video is displayed in the video display area of the video frame, the slide is displayed in the slide display area of the slide frame, and the chat data is displayed in the chat content display area of the chat frame. Described to be displayed.

The description file of each frame of the program screen is automatically generated by using the existing web technology (CGI, ActiveServerPage, etc.). The description file contains information necessary to correctly display slide data, chat data, and video data of the selected program (slide file name, chat data storage file name, multicast address and port number for receiving video data). Such)
Is generated. Furthermore, if the program has already been started when the program screen is displayed, the slide data displays a slide file synchronized with the distribution video at that time.

As described above, the synchronized content is registered as a program with the distribution time determined, the program information is presented to the viewer in the form of a program guide, and automatically distributed at the designated time to view the program. Preparation can be realized with simple procedures. As a result, the student can select and view a program that meets the needs from many contents. Also, in this case, a plurality of distribution destination multicast addresses are properly used like a TV program channel, and simultaneous distribution of a plurality of contents can be efficiently operated by a simple procedure.

Conventionally, it has been necessary to prepare and distribute a lecturer screen and a student screen for each content in advance, and then manually distribute the program. Therefore, when the number of programs increases, the amount of work increases, and efficient operation cannot be performed. However, according to the present invention, simultaneous distribution of a plurality of programs can be performed by a simple operation by expanding the functions.

Next, the information receiving apparatus 500 executes
The operation of recording a registered program will be described. From the program guide screen shown in FIG. 7 displayed on the Web browser of the information receiving device 500, the storage reservation of the programs listed on the program guide screen by the storage reservation input / display unit 49 can be made. In addition, the storage scheduling unit 50 accumulates the broadcast synchronous content in the storage device 7 of the information receiving device 500 during the broadcast of the program reserved for storage according to the reserved schedule. This processing procedure will be described with reference to FIG.

FIG. 12 is a flowchart showing the processing operation of the accumulation scheduling processing. First, FIG.
Check the storage reservation check box next to the program name on the program table screen shown in FIG. When the operation of checking this check box is performed, the storage reservation input / display unit 49 executes the following processing.

First, the storage reservation input / display unit 49 selects a checked program on the program guide screen, and acquires the program ID of the selected program (step S31). Next, the program
Using the ID as a clue, the program attribute file of the corresponding program is specified from the program attribute files stored in the storage device 7 connected to the information transmitting device 500. Next, the program attribute file is read, and attribute information (program ID, program name, start time, end time, channel number) necessary for executing the storage process is obtained.

Next, as a process of registering the storage reservation information, the previously acquired attribute information is written in a storage reservation file stored under a dedicated storage directory created in advance in the storage device 7. That is, the previously acquired attribute information is registered in the storage reservation information (step S32).
Subsequently, the storage scheduling unit 50 is requested to perform a storage reservation process, and transmits the attribute information of the program acquired earlier. One storage reservation file exists in one system. As described above, additional writing to the storage reservation file is performed every time a storage reservation occurs.

FIG. 13 is a diagram showing an example of the description format of the storage reservation information. In FIG. 13, attribute information (start time, end time, program ID, program title, channel number) of a program reserved for storage is registered. The attribute information of these registered programs stores values acquired from the program information file. The storage reservation input / display section 49 refers to the storage reservation file stored in the storage device 7 to generate and display a reservation program list screen for displaying a list of storage reservation states registered in the system.
Display can be performed.

Next, the storage scheduling unit 50 receiving the request from the storage reservation input / display unit 49 calculates the time from the current time to the program start time (step S3).
3). Since the program is actually stored from the program start time, the standby time from the current time to the start of the program storage process is obtained. Further, the accumulation scheduling unit 50 waits for the waiting time until the start of the previously obtained program (step S34).

Next, the accumulation scheduling unit 50 waits for the elapse of the previously obtained standby time, and when the start time of the program reserved for accumulation is reached, the recording / reproduction unit 47 starts the accumulation processing of the program. Request. The recording / reproducing unit 47 starts the storage process of the designated program in response to this (step S35).

The program storage operation of the recording / reproducing section 47 is performed in the following procedure. First, the recording / reproducing unit 47 of the information receiving device 500 converts the video data of the program out of the video data output from the video receiving unit 41 from the connected storage device 7 from the program start time to the end time. And save it as a video file.

Similarly, each time the slide specifying information receiving section 43 receives the slide specifying information of the corresponding program from the program start time to the end time, the recording / reproducing section 47 starts the program starting time at that time. Is recorded on the connected storage device 7 as a slide synchronization information file together with the elapsed time of the received program and the received slide specifying information of the corresponding program.

The slide identification information received by the slide identification information receiving unit 43 is transmitted from the information transmitting apparatus 200 at the point A by the instructor.
Is generated and transmitted by the slide specifying information transmitting unit 24 each time a slide switching operation is performed on the screen. The slide specifying information includes information for specifying a slide, such as a switched slide file name.

If a chat is exchanged during the program distribution, the file of all chat data (text) displayed in the chat content display area of FIG. Further, the recording / reproducing unit 4
Reference numeral 7 denotes the slide synchronization file in which the file name of the video file to be recorded first, the slide file name of the first page, the slide file name of the last page, the number of slides (the number of slide files), and the chat data file name are included. If it exists, the chat data file name is also recorded.

As described above, the program reserved for storage by the operation of step S31 is completely recorded on the storage device 7 of the information receiving apparatus 500 reserved for storage after the end of the program distribution. And can be played back and viewed.

The operation of reproducing the synchronous content reserved for storage will be described with reference to FIG. FIG.
FIG. 8 is a flowchart of a synchronous reproduction process of synchronous content accumulated by accumulation reservation. First, the recording / playback unit 47
Reads the slide synchronization information file of the specified stored program and acquires the name of the video file to be used (step S4).
1). Next, the video display unit 42 starts preparing to read this video file (performs buffering processing for absorbing delay at the start of reproduction) (step S4).
2) Further, the slide display unit 44 acquires a slide file name to be displayed first (step S43).

Subsequently, the recording / reproducing section 47 causes the video display section 42 to start reproducing the video when the preparation for reproducing and displaying the video file is completed (step S44). The first slide for which the file name has been acquired is displayed (step S45). Also,
The elapsed time is measured with this timing as a starting point (step S46).

Thereafter, the recording / reproducing unit 47 monitors the progress of the elapsed time, and when the slide operation time recorded in the synchronization information file has come, a display switching request to the slide file switched at that time is sent to the slide display unit. 44 (SStep S47), and in response, the slide display unit 44 executes slide switching (Step S4).
8).

Similarly, the recording / reproducing unit 47 performs slide switching according to these recordings until the data of the elapsed time at the time of the slide operation and the data of the switched slide file name stored in the slide synchronization information file are exhausted. The program is executed by the slide display unit 44. Thus, the slide switching synchronized with the video is reproduced at the same timing as when the program is broadcast. Further, when the video reproduction ends (step S49), the recording / reproducing unit 47 ends the measurement of the elapsed time (step S50).

If the playback position is skipped during video playback, the changed playback position is obtained, and the elapsed time from the playback start position is recalculated therefrom. Refer to the synchronization information. Further, when the chat data is included in the reserved content, the stored chat display / transmission unit 51 displays all the recorded chat data on the chat content display area in FIG.

As described above, it is possible to record a program in the same manner as a TV broadcast, and to repeatedly watch when desired to watch the content at its own convenience without missing the contents required for the student. Convenience and effective use of synchronized content.

Next, the operation related to chat when the stored program is reproduced will be described. FIG. 15 is a flowchart showing a processing operation of the chat processing at the time of reproducing the stored program. First, a program reproduction screen for reproducing the stored program is displayed, and reproduction of the synchronized content is started. Here, the program reproduction screen is a screen similar to the program viewing screen of FIG. In this reproduction process, the stored chat display / transmission unit 51 sets the program ID of the program to be reproduced at the start of program reproduction.
Then, the terminal ID of the own terminal performing the reproduction, that is, the terminal ID of the information receiving apparatus 500 is obtained, and these two values are combined and stored in the storage device 7 as the program reproduction information (step S51).

The terminal ID is a unique number given to each information receiving device 500 in order to identify each information receiving device 500 in the system. In this system, each information receiving device 5
00 is assigned a terminal ID, and this terminal ID is stored in the storage device 7.

In the chat frame section of the program reproduction screen, the stored chat display / transmission section 51 inputs and transmits text as well as the display of the recorded chat text, as well as the program screen for program viewing during program broadcast. I can do it.

Next, a question or the like generated while continuing to play back the stored program is written in the chat writing area of the program playback screen similar to the program viewing screen shown in FIG. 8, and the transmission button of the program playback screen is clicked. (Step S5
2).

By performing the operation of clicking the transmission button, the chat display / input unit 45 transmits the chat text previously written in the chat writing area to the stored chat display / transmission unit 51. The storage chat display / transmission unit 51 combines the received chat data with the terminal ID and the program ID previously stored on the storage device 7 in step S41, and transmits the combined data to the information transmission device 200 as the storage chat information ( Step S53).

Next, the stored chat receiving / analyzing unit 32 of the information transmitting device 200 receives the stored chat information transmitted by the information receiving device 500 and stores it in the storage device 6 (step S54). Also, the accumulated chat reception / analysis unit 32
By analyzing the program ID and terminal ID of the stored chat information stored earlier, the received chat data is identified to which program the chat data is transmitted from which information receiving device 500, and the received chat data is identified. A process of notifying the data to the instructor is performed (step S55).

Here, notification of the received chat data to the instructor is performed, for example, as follows. In advance, the program ID of each program, the e-mail address of the instructor, the terminal ID of each information receiving device 500, and the e-mail address of the student who is the user of the information receiving terminal are stored in the storage device 6 of the information transmitting device 200. Register.

If the stored chat receiving / analyzing unit 32 specifies the program in charge from the program ID of the previously received storage chat information and performs transmission processing to the e-mail address of the instructor,
It is possible to identify which program the chat data transmitted from the program reproduction screen to the information receiving apparatus 200 when the stored program is reproduced from the student's information receiving apparatus 500 to the instructor.

Further, the stored chat receiving / analyzing unit 32
However, if the e-mail address of the information receiving apparatus 500 corresponding to the terminal ID is acquired from the stored chat information received earlier and attached to the above e-mail to the instructor, and transmitted, After receiving the e-mail and confirming the content of the question, the answer to the question can be returned to the requester by e-mail.

As described above, it is possible to identify which program the chat data transmitted from the program reproduction screen belongs to. Also, a time lag may be determined, for example, by specifying a relevant program from the stored chat data stored in step S44 and automatically transmitting the received chat text separately by e-mail to the e-mail address of the registered program instructor. However, even after the end of the program broadcast, it is possible to provide a two-way communication means between the student and the program lecturer in some way. That is, the student can transmit the chat data not only during the broadcast of the program but also during the playback of the stored synchronized content even after the end of the program, and can ask questions to the instructor. Also, unlike during the broadcast of a program, there is a time lag until the student receives an answer from the lecturer, but a means for performing two-way communication between the student and the program lecturer can be provided.

Furthermore, the student can send questions and opinions to the instructor at any time, and the learning effect of the program can be enhanced as compared with the case of only storing. In addition, the instructor can respond to more questions from students and obtain various opinions, and can obtain hints for more efficient and effective lectures.

Next, an operation related to collection of history information of a viewing / storage reservation operation of a student will be described. FIG. 16 shows the history of various operations performed by the user, such as the viewing history and the accumulation history, transmitted from the history information generation / transmission unit 52 of the information reception device 500 to the information distribution device 200, and the history information reception unit of the information distribution device 200.
