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.

Abstract: A DTV transmitting system includes an encoder, a randomizer, a block processor, a group formatter, a deinterleaver, and a packet formatter. The encoder codes enhanced data for error correction, permutes the coded data, and further codes the permuted data for error detection. The randomizer randomizes the coded enhanced data, and the block processor codes the randomized data at an effective coding rate of 1/H. The group formatter forms a group of enhanced data having data regions, and inserts the coded enhanced data into at least one of the data regions. The deinterleaver deinterleaves the group of enhanced data, and the packet formatter formats the deinterleaved data into corresponding data bytes.
