MULTIMEDIA INTEGRATION SYSTEM OF EARTH WAVE/SATELLITE DIGITAL MULTIMEDIA BROADCASTING AND ITS METHOD

摘要

A multimedia integration system in a terrestrial/satellite DMB(Digital Multimedia Broadcasting) and a method therefor are provided to avoid the complexity in circuit design caused by performing a decoding process through different constitutions for a terrestrial type and a satellite type. A TS(Transport Stream) interface unit(101) selectively interfaces terrestrial TS packet data or satellite TS packet data. A demultiplexer(103) demultiplexes the terrestrial TS packet data or the satellite TS packet data into A PES(Packetized Elementary Stream), and sorts them into audio data and video data. A memory control unit(105) buffers the audio data in a memory, and draws out the buffered audio data. An audio decoder(107) selectively decodes the drawn terrestrial audio data or satellite audio data. A DAC(Digital-to-Analog Converter)(109) converts the decoded audio data into an analog signal, and outputs the analog signal through a speaker. A video decoder(111) decodes the video data. An LCD panel control unit(113) converts the decoded video data of Y,Cb,Cr into video data of R,G,B, and outputs the converted video data through a monitor.
