Abstract
A service multiplexer of a digital broadcasting system includes a null data generator, a mobile service multiplexer, a main service multiplexer, and a multiplexer. The null data generator may generate null data. The mobile service multiplexer may multiplex and output compression encoded mobile service data, additional data for a mobile service, and null data at a pre-determined first data rate. The main service multiplexer may multiplex and output compression encoded main service data and additional data for a main service at a pre-determined second data rate. The multiplexer may multiplex the output data of the main service multiplexer and the output data of the mobile service multiplexer at a pre-determined third data rate and transmitting the multiplexed data to at least one transmitter located at a remote position.
