Abstract: In a terrestrial DMB, a transmitting apparatus multiplexes a plurality of service streams generated for any service to a plurality of ensembles. In this case, the same sending time data is constructed in a time stamp field of each frame for each of a plurality of ensembles. With this configuration, a plurality of transmitting apparatuses can send a plurality of transmission frames including service streams for the same service at the same point of time, and thus receiving apparatuses can actually receive a plurality of transmission frames at the same point of time.
