摘要

Digital television transmitter to encode key data, and orumizados coding method of main data and optimized in a transmitter of digital television, digital television has a transmitter and a method of encoding data and highlighted in the main transmi Ssor digital television; digital television transmitter.A byte symbol converter converts main and enhanced data packets into symbols, in which at least one of the data packets may include retainers, local data to symbols with known data; a data generator generates a symbol known known data; a P. Rocessador symbol is a symbol representative of the first byte symbol converter; here,The processor of the symbol may post decode a first bit of the symbol of known data and send the decoded bit and a data bit of initialization when the first symbol is a symbol that represents one of the retainers of local; an encoder trellis has one or more memories. For trellis encoding of a second symbol of the symbol processor.In which memories are initialized when the data bit string is processed in the encoder trellis.
