1.function featuresCU84 combines pictures and sound decoding circuit, whose main function is to switch the CD and CD-ROM mixed digit signals of MPEG-I standard compressing codes into the audio digital signals and video digital signals, so that the signals are easy to turn back to analog audio and video signals through audio and video D/A converting circuit. The circuit contains the CPU connector, CD connector, internal DRAM/ROM connector, MPEG-I decompressing unit, symbol generator (OSD), audio/video connector and other circuits. The internal circuit of the chip is shown in figure 1.
