AbstractAn information processing apparatus includes a channel selection task. The channel selection task controls an application program interface (API) to load a detecting microcode into a transport stream processor. The transport stream processor detects a transport stream based on the microcode, and outputs a signal representing detection of the transport stream to an interruption handler. The interruption handler outputs a semaphore signal to the channel selection task. The channel selection task controls the API to output an audiovisual microcode to the transport stream processor. The transport stream processor acquires program-specification information based on the microcode. The transport stream processor performs direct memory access transfer of the information to a memory, and outputs an interruption signal representing completion of the transfer to a software driver. The interruption handler outputs a semaphore signal representing completion of the transfer to the channel selection task. The channel selection task analyzes the information from the memory, and controls the transport stream processor to output a list of programs.
