Patent ID: 7711249

Claim:
A recording and reproducing apparatus for recording a first packet stream containing first AV transport packets and first data table packets for managing the first AV transport packets, the recording and reproducing comprising: a demultiplexer for demultiplexing the first packet stream into the first AV transport packets and the first data table packets; a memory for storing the first data table packets, wherein the first data table packets contain parental control information; an AV decoder for decoding the AV transport packets and outputting AV data; an AV encoder for encoding the AV data and outputting second AV transport packets; a data table packet generator for constructing second data table packets, based on the first data table packets stored in memory, for managing the second AV transport packets; and a multiplexer for multiplexing the second AV transport packets and the second data table packets, and outputting the multiplexed second AV transport packets and second data table packets in a second packet stream; wherein the second data table packets contain parental control information.
