TRANSMISSION APPARATUS, TRANSMISSION METHOD, RECEPTION APPARATUS, AND RECEPTION METHOD

To allow good transmission and reception of a plurality of streams of data corresponding to respective ones of a plurality of data channels. A transmitting side transmits a plurality of streams of data corresponding to respective ones of a plurality of data channels, through a transmission path. At this time, the transmitting side inserts, into each of the plurality of streams of data, identification information for identifying the corresponding data channel. A receiving side determines to which of the data channels each of the plurality of streams of data corresponds, on the basis of the inserted identification information. Thereafter, on the basis of the determination result, the receiving side processes the plurality of streams of data.
