Method for formatting digital broadcast transport stream packet for improved receiving performance, digital broadcast transmitter, and signal processing method thereof

Abstract From the Canadian patent

A method of formatting a digital broadcast transport stream packet a digital , broadcast transmitter, and a signal processing method thereof includes , constructing a transport stream packet that includes a stuffing region for an insertion of a known supplementary reference s equence (SRS) data therein randomizing the packet that includes the stuffing region is randomized and , the SRS data is inserted into the stuffing region of the randomized packet. Adding a parity for an error correction to the packet into which the SRS data has been inserted, the packet to which the parity has been added is interleaved, and a trellis encoding of the interleaved packet is performed. Inserting a …
