BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, an outline of the data broadcasting system according to the present invention will be described. This data broadcasting system simply provides a program as a broadcasting service when broadcasting multimedia information including video, audio, characters, etc. mainly to a terminal device or a mobile terminal mounted on a mobile body. Instead, the main purpose is to provide information that allows the program content itself to flexibly meet the needs and usage situations of the user. In addition, we will provide a broadcasting service from a new perspective by fusing multiple broadcasting services and further fusing with existing media.

In order to realize the above-mentioned broadcasting service, this system is intended for broadcasting mainly to mobile bodies and portable terminals using broadcasting satellites or communication satellites, and CDM is used as a transmission system.
(Code Division Multiplex) method, MPEG4 (Moving Picture Coding Experts Group 4) as an encoding method
And S for the downlink from the satellite to the terminal
By using the band, even a mobile terminal device such as an in-vehicle terminal device or a portable information terminal device can receive multimedia information including video, audio, characters and the like.

By the way, this system assumes the use of MPEG4 as described above. MPEG4 is based on the conventional moving image encoding method in which an image is simply encoded as one scene, whereas a plurality of AVs is used.
A scene is expressed by synthesizing a layered video / audio signal composed of Os (Audio / Visual Objects: components represented by a person and a background). Each hierarchical component may be a natural image / audio or a composite image / audio. Further, it may represent the whole scene or a part thereof. Furthermore, there is a great degree of freedom in the degree of overlap of each component and the temporal / spatial relationship.

That is, in the present system using MPEG4, on the transmitting side, a plurality of contents (objects) forming one scene and the scene description data for synthesizing these contents are respectively selected by an optimum algorithm. It is encoded into a mental stream, and then multiplexed and transmitted. The receiving side decodes each received object and scene description data, synthesizes each object according to the content of the scene description data, and outputs the combined object to a presentation device such as a display or a speaker.

According to such a system configuration, each scene of the program content is composed of one or more contents and transmitted, so that it becomes possible for the receiving side to select and reproduce the contents as necessary. From this, it becomes possible to selectively reproduce a part of the program content according to the user's designation, the broadcast station's designation, and the usage conditions, and the program content itself can flexibly meet the needs and usage conditions of the user. It is possible to present corresponding information.

By the way, if the contents are combined and presented only in accordance with the scene description data, the presentation may be inappropriate depending on the situation of the terminal device. For example, if the content has locality and is always displayed, the terminal device displays the content irrelevant to its own current position.

On the other hand, in the new broadcasting system as described above, a plurality of broadcasting stations independently specify a broadcasting service area so that national broadcasting and regional broadcasting can be arbitrarily selected. Has been proposed. in this case,
In a mobile terminal device or a mobile terminal, it is meaningful for the user if the user can simultaneously receive the required broadcasting service as the user moves. In addition, if existing media such as terrestrial broadcasting (television broadcasting, radio broadcasting) and communication means through public communication networks can be integrated, it will provide a new living environment for users, Can contribute to development.

A data broadcasting system based on the above problems will be described below with reference to embodiments.

FIG. 1 is a conceptual diagram showing an overall image of a data broadcasting system according to the present invention, together with other infrastructures. This data broadcasting system is a kind of satellite broadcasting, but here, in order to distinguish it from BS or CS satellite digital broadcasting for existing fixed terminals, it is called a mobile satellite broadcasting (MSB) system, and its broadcasting wave is described as an MSB wave. To do. The present invention is not limited to the mobile satellite broadcasting system, but can be applied to a data broadcasting system that mainly broadcasts to mobile reception terminals at a low transmission rate.

In this mobile satellite broadcasting system, the broadcast wave transmitted from the mobile broadcasting station 10 is transmitted to the MSB broadcasting satellite 2
Received at 0 and sent to within the specified service area (all over Japan). The mobile reception terminal 30 that receives MSB waves transmitted from the MSB broadcasting satellite 20 is a mobile phone 40.
Can be connected (may be integrated), and the Internet service provider 50 can be accessed through this mobile phone.

The mobile broadcasting station 10 receives the program information created / edited by a plurality of program providers, channel-multiplexes each program information, and then converts it into a broadcasting signal, for example, in the Ku band (12.5-18 GHz). The data is transmitted to the MSB broadcasting satellite 20 via the upstream transmission path. A CDM (Code Division Multiplex) method is used as the channel multiplexing method.

After receiving the Ku band broadcast signal, the MSB broadcasting satellite 20 converts it into an S band signal by a transponder. Then, the converted S band broadcast signal is transmitted to the service area. By transmitting broadcast waves in such a high frequency band, M
SB waves can be received. This contributes to downsizing of the mobile reception terminal 30.

In this embodiment, C is used as another infrastructure.
The S satellite broadcasting will be described as an example. In FIG. 1, CS
Broadcast waves sent from the broadcasting station 60 are sent to all over Japan via the CS broadcasting satellite 70. CS subscriber home 80
Then, the CS antenna 81 receives the CS wave, and the CS receiver 8
2 allows reception and reproduction.

A data storage management device (hereinafter, referred to as a storage dock) 90 for managing the storage data of the terminal 30 is prepared. The storage dock 90 incorporates a large-capacity storage medium such as a hard disk, captures stored data from the terminal 30 and stores it in the storage medium, and provides the stored data to the terminal 30 in response to a request. Further, the storage dock 90 can access the Internet service provider 50 through a telephone line or connect with the CS receiver 82 through the IEEE 1394 network to reserve and record a CS broadcast program.

Here, in the mobile satellite broadcast,
Its main purpose is for mobile terminals. Therefore, considering the storage capacity and battery capacity of the terminal, it is not possible to force a large amount of data to be downloaded for viewing the program.
In particular, mobile satellite broadcasting has a lower data transmission rate than network systems such as CS broadcasting and the recent Internet. Therefore, if the cooperation between the mobile satellite broadcasting and the CS broadcasting or the network system is realized, it is meaningful for the viewers to distinguish the information acquisition / viewing.
As one form thereof, a case where simple information is broadcast by mobile satellite broadcasting and detailed information is provided by CS broadcasting or a network system will be specifically described below as an example.

In the system shown in FIG. 1, simple information is distributed from the data provider (content providing server) 100 to the mobile broadcasting station 10, detailed information is distributed to the CS broadcasting station 60, and the mobile portable receiving terminal is provided by each broadcasting wave. 30 and CS receiver 82. It is assumed that the detailed information is also distributed to the Internet provider 50 and an information providing device (hereinafter simply referred to as a convenience store) 110 arranged in the convenience store. If you pay for detailed information, data provider 1
00, the Internet service provider 50, and the convenience store 110 are linked with the electronic payment system 120 so that the user can be charged for downloading the detailed information.

In the above system configuration, when the mobile portable receiving terminal 30 wants to view the simple information and wants to view the detailed information, there is the following acquisition method.

As the simple information, for example, when the detailed information is an introductory article of a magazine, the headline portion of the article or the summary information of the content is sent.

First, if the user wants to view the simple information while going out and want to view the detailed information on the spot, he / she accesses the Internet service provider 50 through the mobile phone 40 and downloads the detailed information from the server. Further, when it is desired to save the communication fee, the user goes to a convenience store 110 nearby, accesses a server installed there, which has already been delivered with detailed information, by wireless LAN or the like, and downloads the detailed information. If you want to watch it later, access the storage dock 90 via the Internet through the mobile phone 40, and
The detailed information of the CS broadcast is downloaded from, and the portable receiving terminal 30 is set in the storage dock 90 after returning home, and the detailed information is acquired and viewed.

A more specific embodiment will be described below.

The data provider 100 determines from the identification code whether the user is a legitimate user, immediately notifies the payment operator of the occurrence of a charge if the magazine purchase is free, and receives the permission notification from the payment operator. The download permission is notified to the receiving terminal 30 (step S1)
8). The data provider 100 registers the terminal ID and the identification code, and sets them so that the information is not provided even if the same identification code is notified from other terminals.

Upon receiving the download permission notification, the mobile reception terminal 30 confirms the detailed information stored in the storage area of the storage dock 90 and downloads the difference information from the already stored simple information (step S19).
After the download is completed, the user is notified that the detailed information can be reproduced (step S20). After that, the detailed programs accumulated can be viewed at any time.

(Second Embodiment) As a second embodiment, FIG. 3 shows a process in the case where the portable receiving terminal 30 uses the network system of the convenience store 110 to purchase and acquire pay detailed information. It is a flowchart which shows a flow.

At the convenience store 110, information can be distributed by a network system connecting chain stores. Therefore, information magazines are sold at each store and an information providing server is installed, and detailed information of the information magazines is registered in the server of each store through a network system.

Under the above-mentioned environment, the mobile reception terminal 30 receives the MSB wave and receives and stores free simple information. This simple information is added with guidance information that introduces an information magazine in which the detailed information is placed and notifies the identification information that is published in the magazine to present the detailed information. If detailed information already exists at the time of reception, the information is replaced at the user's discretion (step S21).

After storing the simple information, the portable receiving terminal 30 reproduces the simple information and views the program (step S22).
If detailed information is desired as a result of viewing the program, the information magazine introduced in the program is purchased at a convenience store, and the identification code individually described in the information magazine is set in the mobile reception terminal 30 (step S23). In this state, connect the mobile reception terminal 30 to the server of the convenience store that purchased the magazine by wire or wirelessly,
It requests the server to download the desired detailed information (step S24).

At this time, the server confirms the presence or absence of the requested detailed information (step S25), and if it does not exist, presents the fact that there is no corresponding information and ends the processing. If there is the corresponding information, the mobile reception terminal 30 is requested for the terminal ID and the magazine individual identification code, and the response result is notified to the information management center (step S26).

At the information management center, it is determined whether the notified individual identification code has already been registered, and if it has been registered, it is determined whether the terminal ID matches the registered content, and only if it matches. Notify download permission,
If they do not match, it is determined that the user is not an authorized user and the download is not permitted. If the individual identification code is not registered, the download permission is notified and the terminal ID and the individual identification code are registered.
The same identification code is set in another terminal so that it cannot be downloaded (step S27). In addition, when billing occurs, billing processing is performed through the electronic settlement system 120 (step S28).

Download permission from Information Management Center /
Upon receipt of the notification of disapproval, the server downloads detailed information (may be difference information from the simple information) to the mobile reception terminal 30 according to the notification (step S29). After that,
It is possible to watch the detailed programs accumulated at any time.

According to the above-mentioned embodiments, paying attention to the fact that the simple contents of "for the time being" can be delivered even in the data broadcasting having a narrow band, it is provided by the broadband CS, the Internet and the network system. It becomes possible to give the opportunity of content purchase. Also,
The latest information can be updated at any time because it is sent from the "for the time being" mobile broadcast wave. It is convenient to store the main device for connection in a convenience store, etc., so that detailed information can be stored even after returning to the office. Furthermore, since the purchase of a product is a condition for obtaining information, it is possible to realize a business development that is tied up with a product provider. Also, for stores such as convenience stores, profits can be obtained by utilizing the network, and tie-up with data broadcasting is possible.

In implementing such an application, when information is downloaded into the terminal through mobile broadcast waves, information that is permanently used for each file or a program that has detailed information is currently held by the terminal. It is advisable to build a database that describes information such as whether it is a simplified version or a detailed version. Therefore, the identification signal for constructing this database is superimposed on the broadcast wave. A similar signal is also superimposed on the broadband side.

It is desirable that the terminal be provided with a button for confirming whether the user desires more detailed information. Further, when the data of the broadcast wave is received again, in order to release the memory, it is possible to improve convenience by providing a button for inquiring whether or not to discard the detailed data.

Further, if the detailed information is automatically replaced by simply placing the terminal on the base unit (storage dock), a complicated operation procedure becomes unnecessary.
