PURPOSE: A TV receiver card for supporting multiple moving picture compression format using DSP(Digital Signal Processor) is provided to be capable of compressing analog picture signals without overloading a CPU or decompressing compressed digital picture information using programmable DSP characteristics. CONSTITUTION: A TV tuner module(10) receives TV signals, and a picture signal input(20) receives video signals. An A/D converter(30) converts analog picture signals into digital signals. A DSP(40) compresses the digital picture information, decompresses compressed digital picture information, or converts the compression format. A PC bus interface(70) transmits data between the TV receiver card and a PC. A D/A converter(50) converts decompressed digital picture information into analog picture signals. A picture signal output(60) outputs the converted analog picture signals to external devices such as a TV or a VTR. |
