By searching the additional data storage unit 23 using D as a key, a directory for the corresponding additional data 310 is specified and deleted, and the area is opened. In the case of reading, the input / output unit 22 reads the additional data 310 stored in the directory corresponding to the program ID notified from the site transmitting / receiving unit 21 among the directories in the additional data storage unit 23,
Output to the site transmission / reception unit 21.

(Operation of Site 20) Next, the operation of the entire site 20 will be described with reference to the drawings. FIG.
5 is a flowchart showing the flow of the operation of the site 20. First, the site transmitting / receiving unit 21 receives a request from the broadcasting station 10 or the receiving device 30 (S801: Yes).

If the requesting source is the broadcasting station 10 and the requested content is the storage of new additional data (S802: "store"),
The site transmission / reception unit 21 includes the additional data itself and the program ID.
Is transmitted to the input / output unit 22, and the input / output unit 22 generates a directory with the program ID in the additional data storage unit 23 and stores the additional data therein (S803).

When the request source is the receiving apparatus 30 and the request is to read additional data (S802: "read"), the site transmitting / receiving section 21 outputs a directory name (program ID) to the input / output section 22. Then, the additional data in the directory is read from the additional data storage unit 23 (S
804), and transmits the additional data to the requesting receiving device 20 (S805).

If the requesting source is the broadcasting station 10 and the request content is erasure of the existing additional data (S802: "erase"),
The site transmission / reception unit 21 outputs the program ID to the input / output unit 22 and instructs deletion, and the input / output unit 22 deletes the directory corresponding to the program ID and the additional data therein from the additional data storage unit 23. (S806). (Receiving device 30
Configuration) The receiving device 30 receives a broadcast program in accordance with the specification of the viewer, and presents it to the viewer in real time or after recording once. When a broadcast program is recorded and presented to a viewer afterward, the additional program data obtained from the site 20 can be added to the received and recorded broadcast program data and reproduced. Here, a description will be given mainly of the processing when receiving and recording.

The viewer holds a program table distributed in advance, and the program table describes the presence or absence of additional information for each program. The viewer can instruct the receiving device 30 to make a reservation recording, and at the time of reservation, designate whether or not additional data is necessary. FIG. 9 is a block diagram illustrating an outline of the receiving device 30 in the program viewing system 1 according to the present embodiment.

The receiving device 30 includes a receiving / extracting unit 31, a program data storing unit 32, an editing unit 33, an acquiring unit 34, and a reproducing unit 3.

The accepting unit 36 accepts a program receiving instruction given by a viewer using an input device such as a remote controller, and transmits the content to the receiving / extracting unit 31. There are two types of reception instructions: real-time program viewing and scheduled recording.
In the case of scheduled recording, an instruction as to whether to acquire additional data is also accepted. In addition, the receiving unit 36 receives a playback instruction of the recorded program from the viewer, and transmits this instruction to the playback unit 35.

The receiving / extracting section 31 receives broadcast data 320 broadcast from the broadcasting station 10 in accordance with a viewer's instruction received via the receiving section 36, and receives the received broadcast data 3
The main program data 312 and the program information 400 are separated and extracted from the program 20. Then, the extracted main program data 312 is extracted.
Is output to the playback unit 35 in the case of real-time viewing,
In the case of scheduled recording, the program data (acquired from the program information 400) and an identifier “M” indicating “main program data” are added and stored in the program data storage unit 32.
Then, in the case of scheduled recording, the reception / extraction unit 31 notifies the editing unit 33 when the storage of the main program data 312 of the program in the program data storage unit 32 is completed.

In the case of scheduled recording, the receiving / extracting section 31 further checks whether or not the viewer instruction notified from the accepting section 36 includes an instruction to acquire the additional data 310. Then, if there is an acquisition instruction, by referring to the additional information flag 402 in the program information 400 (see FIG. 4) included in the broadcast data 320, and confirming the presence or absence of the additional information, the site address also included in the program information Contents of information 403 (movie 3
00, the URL “http: www.XXX.c” including the site address of the site 20 and the name of the additional data storage directory.
o.jp/movie300 ”) to the acquisition unit 34 to instruct acquisition of additional data.

The acquisition unit 34 includes a modem as hardware, a browser software as software, and connects to the site 20 via the Internet N,
The additional data 310 is obtained. When the URL is output from the receiving / extracting unit 31, the acquiring unit 34 connects to the site 20 based on the site address portion of the URL, and connects the directory name portion of the URL (corresponding to the program ID, "movie300"). )) To receive (download) the additional data 310 of the desired program. Then, the acquiring unit 34 extracts the additional program data 311 and the configuration information 500 from the acquired additional data 310, and indicates that the additional program data 311 is a program ID (the directory name) and “additional program data”. The identifier “A” is added and stored in the program data storage unit 32, and the configuration information 50
The value 0 is output to the editing unit 33.

The editing unit 33 is activated at the timing when the reception / extraction unit 31 receives the notification of the completion of the storage of the main program data 312 in the program data storage unit 32 and the output of the configuration information 500 from the acquisition unit 34, and Data files (main001, main002, main003, main0) included in the program data 312
04) and the data files (add001, add002, add003) included in the additional program data 311 are rearranged in the order according to the configuration information 500 (see FIG. 5) to generate the reproduction program data 330 and add the program ID. Then, it is stored in the program data storage unit 22. In the example of movie 300, main001 →
add001 → main002 → add002 → main003 → add003
→ Rearranged in the order of main004 and program data for playback 330
Will be generated. The editing process performed by the editing unit 33 is non-linear editing.

Upon receiving a program viewing / reproducing instruction via the receiving unit 36, the reproducing unit 35 performs a process such as decoding on the program data, converts the program data into a display format, and outputs the program data to the display device D. When watching in real time,
The main program data output from the extraction unit 31 is reproduced. In the case of viewing a recorded program, the reproduction program data 330 corresponding to the program ID output together with the instruction is read from the program data storage unit 32 and subjected to reproduction processing.

The storage section 32 is a data recording medium, and has a capacity for recording several hours of audio / video data. Further, the storage unit 32 is a recording medium that can be randomly accessed, and can perform non-linear editing on the stored data. (Operation of Receiving Device 30) Hereinafter, the operation of the receiving device 30 will be described with reference to the drawings.

FIG. 10 is a flowchart showing the operation flow when the receiving device 30 receives and reproduces a broadcast program. First, the receiving unit 36 receives a viewing request from a viewer (S1001: Yes), and notifies the receiving / extracting unit 31 of the content of the request (target program, real-time viewing / recording, necessity of additional data, and the like).

In the case of real-time viewing (S1002:
“Viewing”), the receiving / extracting unit 31 immediately starts receiving the broadcast data 320 of the program, separates / extracts the main program data 312, and transmits it to the reproducing unit 35 (S1003).
The reproduction unit 35 performs reproduction processing such as decoding on the main program data 312 and outputs the main program data 312 to the display device D (S1004). In the case of recording reservation (S1002: “recording”), the receiving / extracting unit 31 waits for the broadcast start of the program (S1005: Ye).
s), the broadcast data 320 is received, and the main program data 31
2 is stored in the program data storage unit 32 (S1006).
If the viewer has instructed to acquire additional data (S1007: Yes), the receiving / extracting unit 31 instructs the acquiring unit 34 to acquire additional data 310 related to the program from the site 20. The acquisition unit 34 determines whether the additional data 3
10, the additional program data 311 is stored in the program data storage unit 32, and the editing information 500 is output to the editing unit 33 (S1008).

When the storage of the main program data 312 and the additional data 311 in the program data storage unit 32 is completed, the editing unit 33 edits these two types of program data in accordance with the contents of the configuration information 500, and Data 33
0 is generated (S1009). If the viewer has not instructed to acquire additional data (S1007:
No), the main program data 312 is treated as it is as the reproduction program data 330.

Thereafter, when the receiving unit 36 receives an instruction to reproduce the recorded program from the viewer (S1010: Yes), the reproducing unit 35 stores the reproduction program data 3 of the program from the storage unit 32.
30 (if there is no additional data, main program data 312)
Is read, subjected to processing such as decoding, and output to the display device D (S1011). (Summary) As described above, according to the broadcast program viewing system 1 of the present embodiment, the broadcast station 10
In addition to the broadcast data 320, additional data 310 is generated and stored in the site 20, and the receiving device 30
20 and additional data 3 from the site 20.
10 is obtained, and the broadcast data 320 is supplied to the viewer in a form supplemented with the additional data 310, so that the viewer can view the broadcast program without being limited to the time frame at the time of broadcasting.

In this embodiment, the additional data 31
Although the acquisition of 0 is performed in parallel with the reception of the broadcast data 320, the timing of acquiring the additional data 310 is not limited to this. For example, if the URL information is stored in the receiving device 30 in advance, only the additional data 310 can be obtained in advance after the recording reservation is received and before the program broadcast starts. At the time of receiving the instruction, it is possible to specify whether or not additional data is required, connect to the site 20 accordingly, and acquire the additional program data 310.

Further, in the present embodiment, the contents of the additional data have been described using a movie as an example, but the applicable program genre is not limited to a movie. In the case of a live broadcast of sports, it is conceivable to add additional data to the game content before the broadcast start time or after the broadcast ends. Further, in the case of a lesson / educational program, it is conceivable to prepare commentary contents of a plurality of levels according to the degree of understanding of the viewer as additional data.

Further, in the present embodiment, the additional data 310 can be obtained only in the case of recording, but may be obtained in real-time viewing. For example, in the case of a program that displays subtitles, subtitle data is acquired from the site 20 and broadcast data 320 is acquired.
May be displayed in a superimposed manner on the display screen. At this time, the content of the configuration information 500 is information for synchronizing the display content of the broadcast data 320 with the caption.

Further, in the present embodiment, the additional program data is integrated with the main program data by editing. However, additional program data which is not premised on integration with the main program data is also conceivable. For example, in the case of a program trailer, in a normal program broadcast, only a short trailer is broadcast in a form inserted between programs, and such a broadcast form is also limited by a broadcast time frame. Therefore, the trailer is stored on the site as additional program data, so that the viewer can obtain the trailer from the site at any time and view it. In that case, the Internet address of the site for the trailer is held in advance by the receiving device, and the viewer instructs the receiving device to identify the trailer identification information indicated in the program table distributed in advance, so that the receiving device can receive the Internet address from the site. For example, a procedure of acquiring a trailer of the designated program may be considered.

Further, in the present embodiment, the URL included in the program information 400 includes the information of the directory, but the URL including the file name further down from the directory is included in the program information. Is also good. In this case, the URL for specifying the file for the additional program data 311 and the URL for the configuration information 500 are stored in the site address information 403 in the program information 400.

Further, in the present embodiment, the information related to the site 20 included in the program information 400 is only the URL, but other information may be included. For example, in the case where editing by the additional program data is a paid service, when the additional program data is to be acquired from the receiving device 30, the authentication information included in the program information 400 is encrypted by a dedicated program held by the receiving device 30 and the site is encrypted. 20 is added to an additional program data transmission request to Then, the site 20 also checks the encrypted authentication information to determine whether to transmit the additional program data. In this case, it is assumed that the encryption program is installed only in the receiving device 30 of the viewer who has signed the paid service contract.

In this embodiment, the configuration information 500 is stored in the site 20, but the broadcast data 3
The configuration information 500 may be included in the ten pieces of program information 400. In that case, the reception /
The extraction unit 31 determines “from the received data to the main program data 3
12 is stored in the memory 33, and the URL is extracted from the program information 400 and output to the acquisition unit 34 ". In addition, the editing information 500 extracted from the program information 400 is output to the editing unit 33. Perform the following processing. Further, the data acquired by the acquisition unit 34 from the site 20 is only the additional program data 311. Further, the content of the additional data 310 in the site 20 is only the additional program data 311.

In the present embodiment, the case where the viewer views the program edited by the receiving device 30 based on the configuration information 500 has been described, but the receiving device 30 and the viewer can interactively add a program. The content of the supplement by the data may be determined. For example, in the case of an educational program, if the viewer cannot understand the content of the explanation only by the commentary in the main program data 312, the detailed description video stored in the additional program data 311 is displayed in response to the viewer requesting a more detailed description. , Additional playback or replacement playback,
Conversely, if the viewer's understanding is high, the main program data 3
For example, it is possible to delete a part of the commentary in step S12. In this case, information for displaying an interface screen for conversation is added to the configuration information 500.

In this embodiment, the additional data 31
0 is obtained from the Internet site, but may be provided to the viewer in other forms. For example, it is conceivable that the additional data 310 is recorded on a recording medium such as an optical disk and provided to the viewer.
In that case, a recording medium reading device is provided as a configuration that replaces the acquisition unit 34.

In this embodiment and its modifications, only the case where additional program data is added to the main program data has been described.

According to the viewing system 200 of the present modified example, the viewer can acquire the program data from the site and view it even if the broadcast program has been missed, so that the viewer cannot view the broadcast program. The degree to which the program is restricted by the broadcast schedule is further reduced.

In the above embodiment and the two modified examples, all the editing information is edited in file units as shown in the editing information in FIG. 5, but the editing unit is the program at the time of reproduction. May be set in units of time (for example, “minutes”) or data units for compression or reproduction (for example, “kilobytes”). FIG. 15 is an example of editing information of the movie 300 in units of time (minutes). In the editing information 1500 shown in FIG. 15, a time column 1530 is provided instead of the file ID column 530 (see FIG. 5). The contents of this column indicate the position in each data of the main program data (type "M") and additional program data (type "A") by the time length from the head of the data. Playing order "1"
Indicates the data for 17 minutes from the beginning of the main program data, and the file “main001” in FIG. 3 and FIG.
Is equivalent to The data of the reproduction order “2” indicates “data for 7 minutes from the beginning of the additional program data” and corresponds to the file “add001” in FIGS. 3 and 5.

If the editing unit is time or data amount,
Finer editing is possible than editing in file units.
