Abstract: A method of receiving a broadcast signal in a receiver. The received broadcast signal is demodulated. The demodulated broadcast signal is parsed to output at least one signal frame. The at least one signal frame includes first data, second data, and signaling data. The signaling data is decoded. The first data and the second data are decoded with different code rates, respectively. The at least one signal frame includes known data for channel estimation. The at least one signal frame includes a plurality of subframes, and the subframes include a plurality of data units. A first data unit in the data units includes the first data, and a second data unit in the data units includes the second data. The signaling data includes information for fast service acquisition which allows the receiver to locate upper layer signaling information. The signaling data further includes information on encoding type of data.

Abstract: A digital broadcasting system and a method of processing data are disclosed. A receiving system of the digital broadcasting system may include a signal receiving unit, a demodulating unit, a demultiplexer, and an audio/video decoder. The signal receiving unit receives a broadcast signal including main service data and an RS frame including a plurality of MPH service data packets. The demodulating unit demodulates data of the RS frame. The demultiplexer identifies an MPH service data packet including an IP datagram of mobile service data with reference to an MPH header of each MPH service data packet in the RS frame, and when a stuffing data is inserted in the identified payload of MPH service data packet, removes the stuffing data from the payload and separates an audio and video data from IP datagram of the mobile service data of the payload, and outputs the separated audio and video data.
