Method for robust transmission of Digital broadcasting transport stream and Digital broadcasting transmission/reception system and signal processing method thereof

摘要

A method for transmitting a digital broadcasting transport stream to be processed and the robust digital broadcasting transmitting and receiving system, and a method of signal processing is proposed. Normal stream (Normal Stream) and the robust stream (Robust Stream) dual transport stream a first area for randomized to receive the (dual transport stream) and inserting the parity for error correction in the randomized dual transport stream including the generation by the parity area is generated dual transmission stream, a first interleaving, and the first interleaved dual transport stream including the robust stream to the convolutional encoding, and the convolutionally encoded robust stream to the interleaving, and then the dual transport de-interleaves a stream, the encoding by inserting a parity for the first area of ​​the deinterleaved dual transport stream. The encoded dual transport stream 2-interleaving, and the second bit of the interleaved dual transmission stream trellis encoded by trellis-encoded dual transport after the stream multiplexing by adding a synchronization signal on the channel multiplexed dual transport stream modulation to transmit. ; Additional reference signal (SRS), Turbo, convolutional, ATSC VSB, compatibility parity
