Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an indoor broadcasting viewing environment in which a digital broadcast receiving device is connected to a plurality of user terminal devices based on a home network, and includes a receiver device 1, a broadcast receiving device 2, a home network 3, It shows that it consists of a plurality of user terminals (4, 5, 6).

In-house broadcasting viewing environment configured as described above generally operates as follows. When the user terminal 4, 5, 6 transmits a request signal for specific content or additional information to the broadcast receiving device 2 through the home network 3, the broadcast receiving device 2 transmits the request signal. The terminal identifies which of the terminals 4, 5, and 6, converts the requested content and additional information into a form suitable for the user terminal performance and the taste of the terminal user, and transmits the requested content and additional information to the requested user terminal.

FIG. 2 is a block diagram showing an embodiment of the environment configuration described with reference to FIG. 1 when the broadcast receiving apparatus and one user terminal apparatus are connected in a network. In this case, the overall configuration is a form in which the broadcast receiving device 10 and the user terminal device 20 are connected by a network 30 such as a home network.

The broadcast receiving device 10 is largely comprised of a broadcast signal receiver 11, a user preference manager 12, a content and metadata storage device 13, and a customized program provider 14. The user terminal device 20 is composed of a broadcast receiving device remote control unit 21 and a customized program playback unit 22. The broadcast signal receiver 11 demodulates / decodes a digital broadcast signal input through a broadcast channel and stores the content in the content and metadata storage device 13. The user preference management unit 12 receives a control signal for the broadcast receiving device 10 of the user from the user terminal device 20, extracts user preference metadata therefrom, and extracts the user preference metadata for the broadcast receiving device. The usage history of the user and the extracted user taste metadata are stored in the content and metadata storage device 13. The customized program providing unit 14 requests a content resource related to scene description metadata about content suitable for the corresponding user terminal device 20 by a request from the user terminal device 20. To transmit.

The user terminal device 20 corresponds to a user's personal terminal device, performs a function of remotely controlling the broadcast receiving device 10 and playing a customized program, and the broadcast receiving device remote control unit 21 and playing a customized program. It is comprised by the part 22.

The broadcast receiving device remote control unit 21 transmits a remote control input to the broadcast receiving device 10 to the broadcast receiving device 10, and the customized program reproducing unit 22 is a scene provided from the customized program providing unit 14. It provides the user with the ability to play back description metadata and content resources as input.

3 is a flowchart illustrating a method of generating a customized program by analyzing user metadata performed by the broadcast receiving apparatus 10 according to an embodiment of the present invention.

The program metadata and the segment metadata for the broadcast program are analyzed (101). In this case, the program metadata includes program information and segment information. The program information is metadata describing the title, outline, keywords, and the like of the program, and the segment information is metadata describing the position of each segment constituting the program and the title, summary, representative frame position, and the like for each segment. Analysis means parsing and extracting the above metadata components.

According to the result of the broadcast program metadata analysis 101, the customized program resource is extracted (102). Custom program resource extraction corresponds to a function of extracting various customized program resources such as titles, outlines, still images for representative frames, and summary videos for each program and segment from the original broadcast program by analyzing the above metadata. In addition, a function of collecting related information existing on the Internet by using link information related to the corresponding program or segment described in the metadata corresponds to a customized program resource extraction function.

Thereafter, the user metadata is analyzed (103). In this case, the user metadata includes content type preference information of the user and performance information of the user terminal device. The content type preference information is metadata about a content type preferred by the user in each user terminal device 20, and an example may be an audio signal of a broadcast program. That is, the user may prefer to consume only an audio signal for a broadcast program in a specific user terminal device, and this information is described in the content type preference information. The user terminal device performance information is metadata describing the performance of the user terminal device. For example, the calculation amount, the storage device size, and the screen size are examples. In this case, analysis means parsing and extracting the above metadata components.

The scene description metadata is then generated (104). The scene description metadata generation may determine how to combine or select the customized program resource extracted according to the custom program resource extraction 102 described above by the user metadata analysis 103 and describe the scene accordingly. Means the ability to create.

The customized program transmission and playback 105 refers to a procedure of transmitting the scene description metadata and the customized program resources generated from the above process in the broadcast receiving device 10 and receiving and playing them in the user terminal device 20. .

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, according to the present invention, not only a high-definition broadcast program can be watched through a broadcast receiving device in a home, but also a broadcast program can be viewed in variously modified forms in various types of user terminal devices connected by a network. To provide.

In addition, the modification procedure of the broadcast program is determined by the performance of the terminal and the program viewing preference of the user in the terminal. This modification procedure has an effect that is automatically performed without the complicated adjustment procedure of the user by automatically extracting the content type preference information from the user history of the terminal device.
