Receiving apparatus and method, program, and receiving system

摘要

A receiving apparatus includes a buffer configured to store packets of a first packet sequence made up of packets extracted from one transport stream that are common to packets of another transport stream and packets of a second packet sequence made up of common packets, a read control section configured to read the packets of the first packet sequence and the second packet sequence stored in the buffer after the passing of a predetermined time after synchronization is established between the packets of the first packet sequence and the packets of the second packet sequence, thereby reconstructing one transport stream from the first packet sequence and the second packet sequence, and an output section configured to output the reconstructed transport stream.

1. A receiving apparatus comprising:
a buffer configured to store packets of a first packet sequence made up of packets extracted from one transport stream that are common to packets of another transport stream and packets of a second packet sequence made up of common packets; read control circuitry configured to read the packets of said first packet sequence and said second packet sequence stored in said buffer after the passing of a predetermined time after synchronization is established between said packets of said first packet sequence and said packets of said second packet sequence, thereby reconstructing one transport stream from said first packet sequence and said second packet sequence; demodulation circuitry configured to perform demodulation processing on the packets and to output the demodulated packets as a demodulated signal, the demodulated signal including a demodulation of the first packet sequence and the second packet sequence; error correction circuitry configured to perform predetermined error correction processing on the demodulated signal, and to provide the demodulated signal to the read control circuitry; and output circuitry configured to output the reconstructed transport stream,
wherein, after the passing of a delay time obtained from information associated with a future extension frame having a structure different from a T2 frame that is a unit in which data is transmitted on the basis of Digital Video Broadcasting-Terrestrial 2, said read control circuitry starts reading packets from said buffer, thereby reconstructing said transport stream,wherein the information associated with the future extension frame includes
a length of the future extension frame and an interval of the future extension frame both being provided to the read control circuitry by demodulation circuitry, the interval of the future extension frame being based on a number of T2 frames arranged between an nth future extension frame and an n+1th future extension frame, anda remainder resulting from division of an index number of one of the number of T2 frames by the interval of the future extension frame.
