An information processing apparatus detects a coding method of an audio signal to be reproduced as a target coding method, selects one of a first control and a second control based on the target coding method and decoding compatibility information stored in a storage unit, and performs the selected one of the first control and the second control, the first control being for obtaining the audio signal from an external storage; decoding the obtained audio signal; and transmitting the decoded audio signal to a speaker apparatus, the second control being for causing: the external storage to directly transmit the audio signal to the speaker apparatus; and the speaker apparatus to decode the audio signal.

Information processing apparatus and control method

An optical disk for recording stereoscopic videos and high-quality video signals and a system for reproducing the videos and signals from the optical disk are made compatible with the conventional video reproducing system. A reproducing device which is used for reproducing stereoscopic videos and high-quality videos obtains stereoscopic video or high-quality videos by reproducing both first and second interleaved blocks on the optical disk in which first and second video signals are alternately recorded on the left and right sides by dividing the first and second video signals into frame groups of one GOP or more and a reproducing device which is not used for reproducing the stereoscopic videos and high-quality videos obtains ordinary videos by only reproducing either the first or second interleaved block by jumping tracks.

High-resolution optical disk for recording stereoscopic video, optical disk reproducing device, and optical disk recording device

A system stream contiguous reproduction apparatus to which are input one or more system streams interleaving at least moving picture data and audio data, and system stream connection information includes a system clock STC generator for producing the system clock that is used as the system stream reproduction reference clock. The system stream contiguous reproduction apparatus further includes one or more signal processing decoders that operate referenced to the system clock STC, decoder buffers for temporarily storing the system stream data transferred to the corresponding signal processing decoders, and STC selectors for selecting a system clock STC referenced by the signal processing decoders when decoding the first system stream, and another system clock STC referenced by the signal processing decoders when decoding a second system stream reproduced contiguously to the first system stream.
