Abstract:
Presented herein are system(s), method(s), and apparatus for rapid switching between streams of data. In one embodiment, there is described a circuit for providing media. The circuit comprises a multiplexed stream processor, a queue, and a decoder. The multiplexed stream processor receives a multiplexed stream and filtering at least one elementary stream. The queue queues the at least one elementary stream. The decoder decodes the at least one elementary stream. The multiplexed stream processor filters at least another elementary stream instead of at least one elementary stream after issuance of a command to switch from the at least one elementary stream to the at least another elementary stream. The queue stores a portion of the at least one elementary stream after issuance of the command, said portion of the at least one elementary stream being written into the queue before issuance of the command. The decoder decodes the portion of the at least one elementary stream and the at least another elementary stream.
