Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcast receiving apparatus, a data service presentation method used therefor, and a program therefor, and more particularly to a BS (Broadcasti).
ng Satellite: Broadcasting Satellite), CS (Com
The present invention relates to a digital broadcast receiving device for receiving a data broadcast or a multimedia service program serviced by digital satellite broadcasting, communication satellites, etc.

[0002]

2. Description of the Related Art In recent years, broadcasting satellites, communication satellites, and cable televisions (CATVs).
Or the digitization of terrestrial broadcasting worldwide,
It has been rapidly progressing, and even if it is viewed domestically, CS and BS digital broadcasting services have already started, and terrestrial digital broadcasting is planned in the future, and preparations for the start of broadcasting are being made.

The major features of digital broadcasting are that the image quality of images based on high-definition is mainly improved, the number of channels is increased by the effective utilization of the transmission band by high-efficiency coding technology and multiplexing technology, and In addition to voice, there are multimedia services by data broadcasting.
In particular, the third type of multimedia service is capable of providing a two-way interactive service from the conventional unilaterally broadcast form. A multimedia service program resulting from this multimedia service is a media service that enables interactive viewing of presentation information that integrates a plurality of expression media such as video, audio, and data.

The types of data broadcasting include a specific program, for example, an interlocking type that supplies a moving image and audio, or a related data service that is associated with audio, and a completely unique form that does not link with other programs. Can be broadly classified as a stand-alone type that provides data services.

For example, when considering the broadcasting of a movie, the main body of the program is composed of video and audio, but as additional information, information strictly synchronized with the video and audio such as subtitles, or the profile of a movie performer, Information synchronized with events such as stories is transmitted as linked data. Further, in the case of independent data, the main body is data, and various services such as weather forecast, stock price information, news, software download, etc. can be provided. Needless to say, both interactive and independent interactive services are possible.

ARIB (Association of
Radio Industries and Bus
sites: The Association of Radio Industries and Businesses) STD-B
The details of the data broadcasting will be described below by taking as an example the data encoding method and the transmission method in the BS digital broadcasting standardized in 24.

As a data broadcasting transmission means, an independent PES (Packetized Elem) advantageous for transmitting data contents linked with a specific program is provided.
The following are defined: an input stream transmission method, a data carousel transmission method for repeatedly transmitting data content at a certain cycle, and an event message transmission method for performing a certain operation on the operating data content.

[0008] The contents of the data broadcast are basically composed of still images, figures, characters and control modules. For example, the still image module is JPEG (Joint
Photographic Coding Expe
rts Group) data, etc.
G (Portable Network Graphi)
cs) data etc., the character module is 8 unit code data etc., and the control module is BML (Broadcast).
It is often composed of documents written in the Markup Language) and these are fixed-length DDs.
It is divided into B (Download Data Block) messages and transmitted. In this case, the additional control information of the DDB is DII (Download Info Info).
Cation) message is transmitted.

Generally, for data broadcasting contents, by selecting one of the main services presented on the screen, the selected service or the sub service item is presented on the next screen, and similarly, the sub service is selected. By that,
It has a hierarchical structure in which a selected service or sub-service item is presented on the screen one after another, and a plurality of services are selectively selected and executed by the operation of the viewer.

Data broadcasting contents are often composed of a plurality of still images, figures, characters, and control modules. For example, the control modules are described in BML language.
Assuming that the document is an ML document, each presentation page has an individual B
When the ML document corresponds, the structure of the data broadcasting content configuration model is as shown in FIG. According to an example of this configuration model, the first to tenth BML documents 101 to 110 corresponding to the control module 100, the still image module 120, the graphic module 150, and the character module 1
60, a moving image 130, and a sound 140.

The service start point is the first BML document 10
1 and the second BML document 102 and the third B from now on.
It branches into the ML document 103 and the fourth BML document 104, and further, the second BML document 102 is moved to the fifth BML document 105 and the sixth BML document 106, and the fourth BML document 104 is changed to the seventh BML. Document 107, eighth B
The ML document 108 and the ninth BML document 109 are respectively branched, and the ninth BML document 109 is the tenth BML document.
It connects to the document 110.

Further, the still image module 120 has a sixth B
In the ML document 106, the moving image 130 and the sound 140 are in the eighth BML document 108, and the graphic module 150 and the character module 160 are in the first to tenth BML documents 101 to 1.
10 is defined as a module that performs a presentation process by referring to a link, that is, a BML document.

According to this configuration model, for example, when the viewer repeatedly desires to view the content corresponding to the tenth BML document 110, the viewer operates the first BML document 101 and the fourth BML every time by himself / herself. Document 104,
While confirming the service presentation by the ninth BML document 109 and the tenth BML document 110 in order, the operation for selecting and executing a desired service item must be performed using a remote controller or the like.

Further, in each step of these BML documents, the presenting process is performed by referring to each mono-media module more or less, so that it takes a huge amount of time to reach the desired content.

[0015]

In the above-mentioned conventional digital broadcast receiving apparatus, when an attempt is made to refer to a service item in a particularly deep layer of a data broadcast program,
There is a problem in that the amount of operation required for the viewer, such as execution of selection, increases in proportion to the number of layers up to that point.

Further, since images are displayed with reference to some of figures, characters, still image modules, or moving images and sounds in each layer, it takes a long time to complete drawing depending on the number of modules to be referred. As a result, there is a problem that the viewer is forced to wait the same amount of time. When the intended service item is repeatedly viewed, naturally, a large amount of operation and a presentation waiting time are forced on the viewer every time.

Therefore, an object of the present invention is to solve the above-mentioned problems, and in a digital broadcast program including a data independent program or a multimedia service program, a time and an operation amount required for presenting a data program service item desired by a viewer. (EN) Provided are a digital broadcast receiving device, a data service presentation method used for the same, and a program therefor capable of significantly reducing
