    摘要: A digital broadcasting system and a data processing method thereof are provided. An apparatus for generating a transport stream includes a packet generator for generating a plurality of packets by compressing video and audio signals; a counter for counting the number of the generated packets and outputting the count result; and an information controller for determining whether the count result of counting reaches a predetermined number of packets, inserting packet start information into the packets according to the count result, and transmitting the packets with the packet start information inserted therein. The packet start information is added to a packet to be transmitted in a transmitter, and the packet start information is extracted from the received packet in a receiver, so that the waste of frequency resources can be reduced.

    摘要: A digital broadcasting transmission and reception system includes a digital broadcasting transmission apparatus and a digital broadcasting reception apparatus. The digital broadcasting transmission apparatus that includes a robust processor that codes a robust stream of a dual transport stream where a normal stream and the robust stream are combined. The robust processor includes a demultiplexer (DE-MUX) that separates the normal stream and the robust stream from the dual transport stream; a robust encoder that appends a parity to the separated robust stream; a robust interleaver that interleaves the robust stream having the appended parity; and a MUX that combines the interleaved robust stream and the separated normal stream. The digital broadcasting reception apparatus includes a robust decoder that decodes a robust stream of a dual transport stream where a normal stream and the robust stream are combined. The robust decoder includes a first decoder that trellis-decodes the robust stream; a robust deinterleaver that interleaves the trellis-decoded robust stream; a second decoder that convolution decodes the deinterleaved robust stream; a robust interleaver that interleaves the convolution-decoded robust stream; and a frame formatter that adds decoded data of the second decoder to a part that corresponds to a position of the robust stream of a frame where the normal stream and the robust stream are mixed. Accordingly, a receiver of a simple structure can be provided.
