DIGITAL BROADCASTING SYSTEM AND METHOD

摘要

A digital broadcasting transmitter comprises a processor for processing a stream to be transmitted, so that the stream is robust against errors, and a Trellis/parity corrector for Trellis-encoding the stream processed by the processor, resetting at least one internal memory used for the Trellis-encoding at a predetermined point in time and correcting a parity changed according to the resetting. The processor includes a first converter for receiving a stream of a byte unit and converting the received stream, an outer encoder for encoding the stream converted by the first converter and outputting a stream of a symbol unit, an outer interleaver for interleaving the stream output from the outer encoder, and a second converter for converting the interleaved stream from a symbol unit into a byte unit.
