Abstract:
A data recording method comprising the processes of:receiving multiplexed data including a plurality of programs from an external source; extracting at least one program out of the plurality of programs included in the received multiplexed data; and recording the extracted at least one program, wherein each of said plurality of programs is divided into a plurality of packets, the programs are time-division multiplexed as the multiplexed data by a unit of the packet, and the extracting process comprises the processes of: extracting, the packets composing the at least one program to be extracted from the multiplexed data; generating packet number data indicating a number of packets pertaining to programs different from the at least one program to be extracted from the multiplexed data, said packet number data being located in the multiplexed data between a packet previously extracted in the packet extracting process and a packet currently extracted in the packet extracting process; and recording the packets extracted in the packet extracting process and the packet number data generated in the generating process.
