ABSTRACT:
Disclosed is an MPEG2 transport decoder including a transport parser unit for storing each syntax field value by parsing, outputting each data identified with the packet identifier PID after collecting from each packet data and outputting the interrupt signal if a pointed resister value of the resist values is set; a CPU interface unit for providing an interface between the resister file of said transport parser unit and each decoder and outputting a signal selecting a transport parser unit or a video decoder, an audio decoder, a data decoder and a memory by decoding the address; a CPU for reading the interrupt resister from said CPU interface unit once an interrupt signal is inputted, detecting if the interrupt signal is inputted from said transport parser unit or from the video decoder, the audio decoder and the data decoder, and decoding according to the program on a memory unit; a memory unit for storing a program of the operations of said CPU; and a decoder interface unit for controlling in order to exchanging the data among said CPU, said transport parser unit and said video, audio, data decoders.
