Information processing apparatus, information processing method, and recording medium

An information processing method comprising:

• a time-division multiplexing step of time-division multiplexing data concerning a first video signal;
• and
• an adding step of adding beginning information to the data which is time-division multiplexed in said time-division multiplexing step, the beginning information indicating the beginning of the data;
• wherein a bit string obtained by decoding the beginning information using a predetermined method differs by at least two bits from two types of bit strings obtained by decoding, using the predetermined method, two types of information indicating the beginning of a plurality of pieces of data concerning a second video signal, when the number of corresponding bits is the maximum.

A recording medium having a computer readable program recorded thereon, the program comprising:

• a time-division multiplexing step of time-division multiplexing data concerning a first video signal;
• and
• an adding step of adding beginning information to the data which is time-division multiplexed in said time-division multiplexing step, the beginning information indicating the beginning of the data;
• wherein a bit string obtained by decoding the beginning information using a predetermined method differs by at least two bits from two types of bit strings obtained by decoding, using the predetermined method, two types of information indicating the beginning of a plurality of pieces of data concerning a second video signal, when the number of corresponding bits is the maximum.
