COMMAND PACKETS FOR PERSONAL VIDEO RECORDER TECHNICAL FIELD OF THE INVENTION

摘要

Command packets for personal video recorder. A transport stream (TS) contains data and also includes a transport packet (TP)/TS formatted command packets. The TP/TS formatted command packet may be communicated between any number of devices, including multiple chips, multiple boards, and multiple processors. A decoder is able to decode the TP/TS formatted command packet and to perform the appropriate operation on data portions of the TS. When a TS is provided to a device not having the capability to perform the proper decoding of the TP/TS formatted command packet, that particular packet may be deemed as being unidentified (or unknown) adaptation field data. Alternatively, the packet may be identified as being corrupted data and/or irrelevant data. The command packets may be encoded into command packets of the transport stream in such a way that it is backward compatible with previous systems.
