Abstract
A media processing apparatus includes an input/output processing unit that performs input/output processing that is asynchronously caused by external factors and a decode processing unit that operates in parallel with the input/output processing unit and mainly performs decode processing for a data stream stored in a memory. The input/output processing receives an asynchronous input of a data stream from outside, stores the data stream into the memory, and supplies a data stream stored in the memory to the decode processing unit. The decode processing unit includes a sequential processing unit and a routine processing unit. The sequential processing unit performs header analysis for compressed video data in the data stream and a complete decode for compressed audio data in the data stream. Based on the results of the header analysis, the routine processing unit performs all of the decoding of the compressed video data aside from the header analysis. In the sequential processing unit, the header analysis is given priority over the decoding of the compressed audio data.
