Abstract
Selective processing of media data is facilitated on a receiving side. A transmission stream in which transmission packets are consecutively disposed is transmitted. Each transmission packet includes a multiplexed transport packet having media data in an upper layer. Identification information representing a kind of media data included in the transmission packet is inserted into the transmission packet. The transmission packet including desired media data is easily recognized and selectively processed on a receiving side.
