Abstract:
1. An information processing apparatus that processes a multiplexed stream including a frame having multiple slots, which is obtained by multiplexing multiple streams containing time information describing times, the apparatus comprising: extracting means for extracting predetermined one or more slots from the frame of the multiplexed stream; storage means for storing data of the slot or slots extracted from the frame; and frequency dividing means for generating a second clock signal by frequency-dividing a first clock signal by a frequency division ratio N:M based on, of the first clock signal, the number of clocks N corresponding to the time for one frame in the multiplexed stream and the number of clocks M for reading the data of the slot or slots extracted from the one frame from the storage means in the time for the one frame, wherein the data of the slot or slots stored in the storage means is read in synchronization with the second clock signal, the stream is a transport stream, and the extracting means extracts a slot storing a predetermined transport stream from the frame and identifies and extracts the slot storing the predetermined transport stream from the frame based on control information including information describing the assignment of transport streams to the slots.
