<p>PROBLEM TO BE SOLVED: To provide a video/audio processing apparatus having high processing performance, without having to operate in high-frequencies for reducing production cost, by performing a series of processes such as input, decoding or output of a data stream representing compressed video data and compressed audio data. SOLUTION: The video/audio processing apparatus is provided with an input/ output unit and a decoding processing unit. The input/output processing unit stores the data stream asynchronously input from the outside into a memory and supplies the data stream stored in the memory to decode processing unit, both of which are performed independently of a decode-processing unit. The decode-processing unit comprises a sequential processing unit for performing header analysis for compressed video data in the data stream and complete decoding for compressed audio data, and a routine processing unit for performing the decoding of the compressed video data other than the header analysis. Of these processing units in the sequential processing unit, the header analysis is given priority over the decoding of the compressed audio data.</p> |
