Abstract: In a method of transmitting broadcasting signals, a transmission frame has the same configuration as that of the existing terrestrial DMB signal. A transmission frame including a base layer service stream is modulated to a base layer, and a transmission frame including an enhancement layer service stream is modulated to an enhancement layer. The enhancement layer service stream is composed of additional data that is not included in the base layer service stream, in order to provide an enhancement layer service. In this way, the method can provide a high-quality service requiring high transmission efficiency while being compatible with the existing terrestrial DMB system. The high transmission efficiency means a higher data transfer rate than that of the existing terrestrial DMB system.

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.
