Embodiment Construction

[0039] Reference is made in detail to the preferred embodiments of the invention and examples illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0040] Figure 4 is a flowchart illustrating the operation of the FIC decoder in accordance with the present invention. refer to Figure 4 , in step 401 the FIC decoder waits for the host to select one of the services included in the group. In step 402, if the host selects a service, the FIB decoder decodes a specific segment of "FIG type 0 segment of extension 1" (0 / 1) included in the FIB, and analyzes the subchannel structure (ie, service elements). In step 403, a specific segment of "FIG type O segment of extension 1" (0 / 2) is activated, and the FIC decoder only decodes information related to the selected service and recognizes the structure of the service. Therefore, if one segment of "FIG Type 0 Segment of Extension...

Abstract

A mobile broadcast receiver and method of decoding broadcast services are disclosed. If the transmission frame includes a synchronization channel, a fast information channel (FIC), and a main service channel (MSC), and group structure information, individual service structure information, and related service element information are transmitted through the FIC, the mobile broadcast receiver receives the above information. If the service desired by the user is selected, the FIC decoder selects from the fields "FIG type 0 of extension 1" to "FIG type 0 of extension 4" in the fast information block (FIB) included in the FIC in the received stream, Only the information related to the service selected by the user is decoded, only the desired service element is filtered from the Fast Information Data Channel (FIDC) and MSC, and the filtered result is transmitted to the corresponding process block. Therefore, the mobile broadcast receiver does not have to decode all information related to a group consisting of a plurality of services, and can decode only services desired by the user.

Description

[0001] This application claims priority to Application No. 10-2004-0065078 filed in Korea on Aug. 18, 2004, which is hereby incorporated by reference. technical field [0002] The present invention relates to mobile broadcast receivers, and more particularly to a method of decoding broadcast services in a terrestrial mobile broadcast receiver. Background technique [0003] Recently, high-quality digital audio equipment such as compact discs (CDs) or digital video discs (DVDs) are rapidly and widely used around the world, and the demands of listeners who require digital broadcast data of high-quality audio data (ie, high-quality sound) are also increasing. Rapid growth. Therefore, in order to eliminate the limitation on improving the quality of audio data used in typical frequency modulation (FM) broadcasting services, digital audio broadcasting (DAB) systems are widely used in many countries such as the United States, Europe, and Canada, etc. The DBA system uses technology ...
