Digital television transmitter to encode data and optimized for main transmission, encoding method of main data and optimized in a transmitter of digital television, digital television receiver and method for decoding a signal in a television receiver type L,Presents a digital television (DTV) transmitter and a method for encoding data in the method of DTV transmitter; data optimized pre processed by data encoding optimized for error correction in front (FEC) and expansion of optimized data encoded by a variable FEC; Atador data generates data packets which include data optimized optimized pre processed and data metThe inserted to at least one of the packet data optimized, a first multiplexer multiplexing the data packets with the optimized main data packets, and a data randomizador randomiza data packets multiplexed; a Reed Solomon (RS) encoder encodes for RS packages Randomized data by adding data of first parity.And a data entrelau00e7ador interweaves the data packets encoded by RS; a trellis encoder trellis coding of the data packets interwoven, where the trellis encoder can be initialized when a data aequ00fcu00eancia known is inse mean to him.
