Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcasting apparatus for transmitting content data constituting a data broadcasting program.

[0002]

2. Description of the Related Art In recent years, television digital broadcasting has been put to practical use in satellite broadcasting, and the stage of practical use of terrestrial broadcasting has also shifted. Digital broadcast programs include ordinary programs such as movies and dramas and data broadcast programs. A normal program is mainly composed of a video stream and an audio stream, and is reproduced at the receiving device simultaneously with reception.

A data broadcast program has a period of, for example, 5 seconds.
By repeatedly transmitting the program data, a pseudo interactive operation is realized for the viewer. A method of repeatedly transmitting program data is called a data carousel transmission method. This program data is composed of a plurality of screen data selectively reproduced by an interactive operation. For example, screen data is BML
(ARI) described in (Broadcast Markup Language)
B STD-B24, version 1.0, "Data broadcasting encoding and transmission schemes in digital broadcasting").

[0004] A data broadcast program may be broadcast as an independent program or in conjunction with a normal program. Hereinafter, a normal program in the case of interlocking is referred to as a main program. In the case of interlocking, for example, a main broadcast program such as a movie is reduced and displayed on a portion of a display screen of a data broadcast program, and introductions and representative works of actors appearing in the movie are displayed on other portions of the display screen. Is displayed in response to the viewer's selection operation. Further, for example, if the main program is a commercial program (hereinafter abbreviated as CM), the CM which is the main program is reduced and displayed on a part of the display screen of the data broadcast program, and the CM is displayed on the other part of the display screen. Will be displayed according to the viewer's selection operation.

FIG. 19 is a diagram showing a broadcast data transmission schedule for a main program and a data broadcast program. In the figure, the vertical direction indicates the time axis, and the horizontal width indicates the band. The broadcast data of the main program includes a video stream and an audio stream, and is broadcast sequentially as time progresses. On the other hand, broadcast data of a data broadcast program is broadcast by a data carousel method. For example, during the broadcast time of CM1, the broadcast data of CM1 is repeatedly transmitted three times.

When such a data broadcast program is used in the receiver, the data of the next screen is received after the viewer performs an operation of selecting the next screen and before the next screen is displayed. Until the time (approximately one cycle). A receiver that eliminates such a waiting time is disclosed in Japanese Patent Laid-Open No. Hei 10-126753. The receiver eliminates the waiting time by storing broadcast data in a memory inside the receiver and reading out a video selected by the viewer from the memory.

[0007]

However, FIG.
As shown in, the broadcast data of the data broadcast program is transmitted in the broadcast time frame of the program in the same manner as the main program, and the receiving device does not store all of the broadcast data immediately after the start of the data broadcast program. There is a problem that the interactive operation cannot be completely used immediately after the start of the data broadcast program for the viewer, and as a result, the display of the next screen selected by the viewer is delayed.

For example, as shown in FIG. 1, even when there is screen data to be reproduced at the same time as the start of the broadcast of CM2, if the broadcast data is included in the hatched portion in the figure, the receiving apparatus uses t2 Otherwise, the screen based on the content data will not be presented. The same applies to CM1 in FIG. In particular, a data broadcast program having a short broadcast time frame such as a CM poses a serious problem.

The present invention is directed to a broadcasting apparatus, a broadcasting method, a program recording medium, and a program for reducing the waiting time in a receiving apparatus from the start of broadcasting of a repeatedly transmitted data broadcast program to the reproduction of the content data for the program. The purpose is to provide. Further, according to the present invention, when a normal broadcast including a video stream and an audio stream and a data broadcast are linked, the normal program of the normal broadcast and the specific program of the data broadcast start reproduction in complete synchronization. It is an object of the present invention to provide a broadcasting device, a broadcasting method, a program recording medium, and a program that enable the above.

Shows an example of the transmission schedule table. As shown in the figure, the video / audio data is transmitted in a program reproduction time frame. Upon receiving the video / audio data, the broadcast receiving device reproduces the data in real time.

Content transmission schedule creation section 103
Is the most characteristic component of the present embodiment, and creates a data broadcasting program transmission schedule table so that contents for the specific program are transmitted prior to the broadcasting of a specific program among the data broadcasting programs. In the present embodiment, the specific programs are CM1, CM2, and CM3 commercial programs.

Content transmission schedule creation section 103
Are used to determine a specific program based on a program title or a program management code, and determine the specific programs CM1, CM2, CM
A transmission schedule table for transmitting the content No. 3 before the reproduction time frame of the program is created. In the present embodiment, as a specific example, these contents are
It is assumed that the program is transmitted during the broadcast of program 1, which is the program immediately before M1.

At this time, the content transmission schedule creation section 103 determines the transmission band of the content of the data broadcast program. That is, the content transmission schedule creation unit 103 allocates a part of the broadcast band for transmitting the content of the specific program during the period before the start time of the reproduction time frame of the specific program, and allocates another part of the broadcast band to the preceding program. , And in the playback time frame, the available bandwidth is allocated as much as possible. However, when another specific program follows the reproduction time frame of the specific program, a part of the band is allocated for transmitting the content of the other specific program. Hereinafter, a period from a predetermined time before the program start time of the reproduction time frame of the specific program to the program start time is referred to as a preceding period. The preceding period is a period immediately before the reproduction time frame, and is a period in which the content of the specific program can be transmitted at least once by a part of the broadcast band.

In the present embodiment, the content transmission schedule creating section 103 determines the transmission band according to the following criteria as a specific example. Further, the band allocated for transmitting the content data of the data broadcast program is D. (Criterion A1) The transmission band of the content of the specific program in the preceding period is set to 0.1D.

When the transmission band of the content of the program preceding the specific program is reduced, the acquisition of the content data of the program in the broadcast receiving device is delayed, so that the content of the specific program uses a narrow band of 0.1D. The data carousel is transmitted with a longer period.
(Criterion A2) The transmission band of the control content is set to 0.05D.

Here, the content for control (hereinafter referred to as control content) is a message instructing the broadcast receiving apparatus to receive the content of a specific program and store it in the buffer, or the content of the content stored in the buffer. This refers to a content consisting only of a message for controlling the broadcast receiving device, such as a message for instructing the broadcast receiving device to start and end the reproduction. The control content has a small data amount. Therefore, even if a narrow band of 0.05D is allocated, the transmission cycle can be shortened.
Allocate a relatively narrow band. (Criterion A3) The transmission band of the data broadcasting program is obtained by subtracting the transmission band of the control program and the transmission band in the preceding period of the specific program from the transmission band D.

The video / audio decoding unit 206 decodes the video / audio stream and sends it to the playback unit 212. The event message decoding unit 207 decodes the event message in the data stream and sends it to the content data processing unit 210.

The data module decoding unit 208 restores the content data by decoding the data module having the ID of 0 in the data stream, and instructs the content data processing unit 210 to cache the content of the specific ID. When received, the data module of that ID is decoded. Then, the data module decoding unit 208 sends the message in the restored content data to the content data processing unit 210, and sends the graphics image and the execution script in the content data to the content writing unit 209 in association with the ID.

[0055] Content writing section 209 stores the content sent from data module decoding section 208 in content storage section 211. When the content data processing unit 210 receives the event message from the event message decoding unit 207 and the message from the data module decoding unit 208, and the received event message indicates that the content is to be deleted,
The content with the ID specified in the event message is deleted from the content storage unit 211. When the received message instructs caching of the content, if the content of the ID specified in the message is not stored in the content storage unit 211, the data module decoding unit 208 is instructed to decode the content of the ID. I do. When the received event message or message instructs reproduction, the content is read from the content storage unit 211 and sent to the reproduction unit 212.

For example, in the period before 8:14:00 (the preceding period of the specific program CM1) shown in FIG. 5, the message M1 is passed from the data module decoding unit 208 to the content data processing unit 210. The content data processing unit 210 determines that ID = 1 and I according to the message M1.
Content data C1002, C1 with D = 2 and ID = 3
003, and instructs the data module decoding unit 208 to decode C1005. As a result, the decoded content data is stored (cached) in the content storage unit 211 by the content writing unit 209. Further, the content data processing unit 210 reads the content C1002 from the content storage unit 211 according to the event message (instruction to reproduce the content data of ID = 1) transmitted at 8:14:00 shown in FIG. Send to 212.

The content storage unit 211 is a buffer for storing content in association with an ID. Playback unit 21
Numeral 2 performs video / audio reproduction and content reproduction.
FIG. 11 shows an example of the playback screen. FIG. 7A shows an example of a reproduction screen of the specific program CM1. In FIG. 7A, the video of the main program CM1 is displayed in a reduced size at the center of the screen, and the content C

Is displayed. The audio of the main program CM1 is also reproduced at the same time. In this manner, the main program CM1 and the specific program CM1 of the data broadcast program are reproduced in conjunction with each other. FIG. 7B is an example of a reproduction screen in which the main program CM2 and the specific program CM2 of the data broadcast program are similarly reproduced in conjunction with each other.

As described above, the broadcasting apparatus according to the present embodiment transmits the content data of the specific program together with the data broadcast program content data preceding in the preceding period of the specific program. The broadcast receiving apparatus can acquire the content data of the specific program before the reproduction time frame, and can realize the entirety of the specific program without waiting for receiving the interactive operation from the beginning of the reproduction time frame. <Second Embodiment> A broadcasting device according to the present embodiment
The difference is that the first content data is sent in the preceding period of the specific program and the second content data is sent in the reproduction time frame as compared with the broadcasting device in the first embodiment. The first content data is, for example, mostly the same as the second content data but partially different. Part of the first content data is the second
The still image is a still image having a higher image quality (having a larger data size) than the content data, or a content representing a quiz or a prize relating to a program preceding the first content data. In other words, the first content data is configured such that the image quality is better, the content is more interesting, or there are benefits for the viewer than the second content data.
This is because the viewer of the first content data views the data from an earlier time.

FIG. 12 is a block diagram showing the configuration of the broadcasting device according to this embodiment. FIG. 3 shows a program information storage unit 1 in comparison with the broadcasting device of the first embodiment shown in FIG.
01, a program information storage unit 1101, a content transmission schedule creation unit 1103, and a data module creation unit 11 instead of the content transmission schedule creation unit 103, the data module creation unit 104, and the content storage unit 113.
04, in that a content storage unit 1113 is provided. Since the same components are denoted by the same reference numerals, description thereof will be omitted, and different points will be described below.

The program information storage section 1101 stores two types of content management codes corresponding to a specific program.
As a specific example, NC10 is used for the specific program CM1.
02 and RC1002, NC10 for specific program CM2
03 and RC1003, NC10 for specific program CM3
05 and the content management code of RC1005 are stored in association with each other.

The content storage unit 1113 stores the content of the above two types of content management codes for a specific program. Here, NC1002, NC1003, N
C1005 is a normal graphics image, RC1
002, RC1003, and RC1005 are high-quality graphics images having the same content as the content and subjected to high-level CG processing.

The data module creation unit 1104 creates a separate data module from the first and second contents. At that time, in order to prevent the first content data cached in the broadcast receiving device from being overwritten by the second content data, each data module is created so as to have a different ID. As a specific example, the data module creation unit 1104 checks the NC
The ID of the data module created from the RC 1002 is 4, and the ID of the data module created from the RC 1002 is 4.
Is set to 1. The ID of the data module created from the NC 1003 is set to 5, and the ID of the data module created from the RC 1003 is set to 2. Also, NC1005
The ID of the data module created from
Assume that the ID of the data module created from 005 is 3.

Content transmission schedule creation section 110
3 creates a content transmission schedule so as to transmit the first content data in the preceding period of the specific program and the second content data in the reproduction time frame. FIG.
3 shows an example of a content transmission schedule. As shown in FIG.
No. 3 creates a schedule for transmitting RC1002 in the preceding period of CM1 and transmitting NC1002 in the reproduction time frame of CM1. In addition, the content transmission schedule creation unit 1103 creates a schedule that sends the RC 1003 in the preceding period of the CM 2 and sends the NC 1003 in the CM 2 playback time frame. Also, the content transmission schedule creation unit 110
3 transmits RC1005 in the preceding period of CM3,
A schedule for transmitting the NC 1005 in the reproduction time frame of M3 is created.

Thus, in the broadcast receiving apparatus, when receiving from the preceding period of CM1, in the reproduction time frame of CM1, the first image having a high-quality graphics image is reproduced.
When the content data is reproduced and received from the reproduction time frame of CM1, the second content data having a normal graphics image is reproduced. The event message sending schedule creation unit 105 creates a schedule in the same manner as in the first embodiment. At this time, when the first content data is cached, the first content is reproduced, and when only the second content data is cached, a message for reproducing the second content data is transmitted. (Summary) As described above, the broadcasting device according to the present embodiment transmits the first content data in the preceding period of the specific program and transmits the second content data in the reproduction time frame. Can provide higher value information to a viewer watching from the same time as a viewer who has started watching from the playback time frame.

In the present embodiment, a case has been described where a part of the first content data is a graphics image having higher image quality than the second content data, but all may be different. For example, in the case of a commercial, the first content data and the second content data may be completely different data relating to the same product (or service). Also, completely different data on different products (or services, etc.) of the same sponsor may be used. (Modification) The embodiment of the broadcasting device according to the present invention has been described above, but it is needless to say that the present invention is not limited to the above embodiment. That is, it goes without saying that the following modifications are also included in the present invention. (1) Regarding the preceding period In this embodiment, as shown in FIGS. 4 and 5, the contents of the specific programs CM1, CM2, and CM3 are all the program start times of the program 1 that is the program immediately before CM1. To the start time of the reproduction time frame of each specific program is set as the preceding period, but the present invention is not limited to this.

Further, the content data of a specific program (CM) may be transmitted within the broadcast time of the program provided by the provider of the CM. (2) Regarding the transmission of the content after the reproduction time frame of the specific program In the present embodiment, the transmission of the content is terminated after the reproduction time frame of the specific program. However, the present invention is not limited to this. Absent. Since the same CM is often broadcast again after a certain reproduction time frame, it may be desirable to repeatedly transmit the CM after the reproduction time frame. Further, continuing the transmission before and after the reproduction time frame in a certain band can simplify the control of the broadcasting device.

FIG. 14 shows an example of a content transmission schedule in this case. As shown in FIG.
The contents of 1, CM2 and CM3 are transmitted in a 0.1D band both before and after the playback time frame. (3) Carousel Transmission In this embodiment, the content data of a specific program is transmitted by a data carousel in the preceding period. This is effective in the case where all of the transmitted content data cannot be obtained due to a reception error or the like, or when a part of data is lost due to buffer overflow or the like in the broadcast receiving apparatus. In a situation in which does not occur, the content data may be transmitted only once in the preceding period. (4) Transmission Band The designation of the transmission band shown in the present embodiment is an example,
It is not limited to this. For example, the following may be used. (A) While a data broadcast program other than a specific program is being broadcast, a fixed transmission band (for example,
0.3D).

FIG. 15 shows an example of a content transmission schedule in this case. In each of the reproduction time frames of the programs 1 and 2 which are not the specific programs, a transmission band of 0.1D is allocated for transmitting the contents C1002, C1003, and C1005 of the specific programs CM1, CM2, and CM3. (B) While a data broadcast program other than the specific program is being broadcast, a fixed transmission band (for example, 0.3D) is allocated for transmitting the contents of the subsequent specific program.

FIG. 16 shows an example of a content transmission schedule in this case. In the playback time frame of the program 1, since it is the preceding period of the specific programs CM1, CM2, and CM3,
CM2, CM3 contents C1002, C1003,
A transmission band of 0.1D is allocated to each of C1005. Further, in the reproduction time frame of the program 2, since the period is the preceding period of the specific program CM3, the content C1005 of the CM3 has 0.3
The transmission band of D is allocated. (C) In the above embodiments, the case where the entire band D is constant has been described. However, the present invention is not limited to this, and may be variable. (5) Event Message In the above embodiments, a message for instructing caching is embedded in the data module with ID = 0 in order to cache the specific program content transmitted in the preceding period in the broadcast receiving device. Alternatively, it may be transmitted as an event message.

For example, C1001 (ID =
0), C1002, C100
3. Message M1 for instructing C1005 to cache
May be sent as an event message instead of embedding the message. Messages M2 to M in FIG.
5 may also be transmitted as an event message. In this case, since the data module of C1001 does not include a message that depends on another program,
It is desirable in terms of reusing data modules (rebroadcasting of programs, etc.).

The control contents S1001
With regard to, only a message instructing caching and reproduction of the content C1002 of the program being broadcast may be embedded, and a message instructing caching of other content may be transmitted as an event message. The time interval for sending an event message is
By setting the time shorter than the transmission cycle of the content, the transmitted content can be quickly cached. For example, assuming that the transmission period of the content of C1002 (ID = 1) (this is calculated from the data amount of the content and the transmission band of the content indicated in the content transmission schedule) is T, the interval is 0.1T. Just send it.

FIG. 17 shows an example of an event message transmission schedule in this case. In the figure, compared to FIG. 5, the contents C1002 (ID = 1), C1003 (I
D = 3), an event message to be cached for C1005 (ID = 5) is sent. Also, I
The event message to be cached for D = 1 is
When T1 is 10 seconds, it is transmitted at intervals of about 1 second.

Further, a message instructing caching and reproduction of the content of a specific program in the reproduction time frame may be sent as an event message instead of being embedded in the control content. Also,
In the specific content, when the event message with the event ID = 1 is received, the designated data module is cached, and when the event message with the event ID = 2 is received, the designated data module is discarded, and the event with the event ID = 3 is discarded. When a message is received, a message instructing to reproduce the designated data module is described, the content is transmitted in advance, and an event message including an event ID and a module ID is transmitted, so that broadcast reception is performed. These instructions may be executed by the device.

When the broadcast receiving device receives the event message, the command is executed immediately after the designated time indicated in the received event message is reached, in addition to the immediate execution type event message transmission for immediately executing the command. A time designation type event message may be transmitted. (6) Specific Program In the present embodiment, a commercial program is described as a specific program. However, the present invention is not limited to this, and a normal data broadcast program may be used as the specific program. In this case, it is desirable that the content data of the specific program does not exceed the storage capacity of the content storage unit 211 (buffer) in the broadcast receiving device.

FIG. 18 shows an example in which the program 3 of the data broadcast program is set as the specific program. As shown in the figure, for example, in the preceding period of the program 3, the content of the program 3 is transmitted with a transmission band of 0.2D. (7) Broadcast Program In the above embodiment, the case where the main program and the data broadcast program are linked is described. However, even when the main program and the data broadcast program are not linked, a desired data broadcast program can be used as a specific program and the present invention can be applied as it is. Of course. (8) Control Content In the present embodiment, the content data of a specific program is cached in the playback time frame and embedded in the control content, and a message instructing to reproduce the content is embedded. Therefore, the control content is required. The present invention can be implemented without this. For example, two types of content to be transmitted in the preceding period and content to be transmitted in the reproduction time frame are prepared as the content data of the CM1. If ID = 0 is set for the frame content, the broadcast receiving apparatus can acquire the content data with the ID = 0 in the reproduction time frame. Alternatively, the ID of both content data may be set to 1, and an instruction to take in the content of ID = 1 may be transmitted as an event message.

Further, C1001 (ID =
0), C1002, C100
3. Message M1 for instructing C1005 to cache
Instead of embedding it, set the ID of C1001 to a value other than 0,
The control content with ID = 0 may be transmitted during the program period, and the message M1 may be transmitted as the control content. In this way, since the data module of C1001 does not include a message that depends on another program, it is desirable in terms of reuse of the data module (rebroadcasting of a program or the like). (9) Embedding Message in Content In this embodiment, the data module creation unit 104
After embedding a message instructing a cache or reproduction in content data, a data module with ID = 0 is created from the content data.
The present invention is not limited to this, and content data in which such an instruction is embedded may be created in advance and stored in the content storage unit 113. (10) Regarding Content Storage Unit In the above embodiment, the broadcasting device pre-transmits the program data for the specific program as shown in FIG. 5, and the receiving device stores the pre-transmitted program data in the content storage unit 211. (Cache). Here, the content storage unit 2
11 is preferably made of a semiconductor memory in terms of access speed, but is preferably a hard disk in terms of storage capacity. The content storage unit 211 may operate at two levels using a hard disk and a semiconductor memory.

In this case, when receiving the event message instructing the deletion of the cached program data, the receiving device deletes only the program data in the semiconductor memory,
If the program data in the hard disk is not deleted for a certain period of time and left after the event message indicating cache is received, if the specified program data is stored in the hard disk, the program data is broadcasted. Read from the hard disk instead of receiving,
You may comprise so that it may copy to a semiconductor memory.

When an event message indicating a cache is received, if the designated program data can be obtained from another medium, the program data is read from another medium instead of being received from the broadcast, You may comprise so that it may copy to a semiconductor memory. Here, the other medium may be an optical disk such as a CD or DVD in which program data is recorded in advance and distributed to users. (11) Alternative to Advance Transmission of Data Broadcasting Program In the above embodiment, the receiving device stores (caches) the program data in the content storage unit 211 and realizes the control by an event message. Both messages are transmitted by broadcasting. Either the program data or the event message may be received by the receiving device from another medium (transmission medium or storage medium).

For example, the receiving device may be configured to receive program data from a broadcast and an event message from the Internet or a telephone line. Alternatively, the program data may be read from a distributable storage medium such as an optical disk, and the event message may be received from a broadcast. (12) Regarding the Program of the Present Invention In the functional block diagrams of the broadcasting device shown in FIG. 1 and the receiving device shown in FIG. 12, a program describing each function is executed by the microcomputer in the broadcasting device and the receiving device. Is realized by: This program is CD, HD
