Patent ID: 8483053

Claim:
An information processing apparatus comprising: encoding means for encoding at least a base stream of an entire stream that may include the base stream and one or more extension streams having extensibility for the base stream; first adding means for adding a same first ID to the stream encoded by the encoding means among the base stream and the one or more extension streams, the first ID identifying the entire stream; second adding means for adding transport priority information to, among the base stream and the one or more extension streams, the stream encoded by the encoding means, the transport priority information indicating priority and respectively distinguishing the base stream from the one or more extension streams; and a packetizing means for packetizing the base stream and the one or more extension streams, to which the first ID and the transport priority information are added by the first adding means and the second adding means, into distinct TS packets, wherein the encoding means encodes first TS packets forming only the base stream and the second TS packets forming the one or more extension streams, which are included in the entire stream, so that the first and second TS packets, to be played back at the same time, are arranged in sequence in the order of the first TS packets forming the base stream and the second TS packets forming the one or more extension streams and such that the first TS packets forming the base stream and the second TS packets forming the one or more extension streams are interleaved.
