An integrated circuit for video/audio processing in which design resources obtained by development of video/audio devices can also be used for other types of video/audio devices. The integrated circuit includes a microcomputer that includes a CPU, a stream input/output for inputting/outputting a video and audio stream to and from an external device, a media processor that executes the media processing including at least one of compressing and decompressing the video and audio stream inputted to the stream input/output, an AV input/output that converts the video and audio stream subjected to the media processing by the media processor into video and audio signals and outputting these signals to the external device. A memory interface controls a data transfer between the microcomputer, the stream input/output, the media processor and the AV input/output and an external memory.

Integrated circuit for video/audio processing

A multiplexing pattern generator generates a multiplexing pattern signal indicating the order of types of data to be multiplexed. A video remaining size calculator and an audio remaining size calculator calculate, as a remaining size, the size of multiplexable data of an elementary stream. A video packet generator and an audio packet generator generate a multiplex packet containing transmission data of a predetermined size, based on the multiplexing pattern signal and the remaining size. A multiplexer generates a multiplexed stream. The video remaining size calculator and the audio remaining size calculator calculate the remaining size, based on the data size per access unit and the transmission size of transmission data. The video packet generator and the audio packet generator generate a multiplex packet, if the data type indicated by the multiplexing pattern signal shows matching, and the remaining size is equal to or larger than the transmission size.
