Patent

CA 2679046

A digital broadcasting receiver and a method for processing a data stream of a digital broadcasting receiver are provided. The receiver includes a demodulator for receiving and demodulating a data stream including known data and a supplementary data stream and an equalizer for equalizing the demodulated data stream. The data stream is transmitted from a digital broadcasting transmitter comprising a data pre-processor for pre-processing the supplementary data stream and a Trellis encoder for performing Trellis encoding on a data stream including the known data and the pre-processed supplementary data stream. The Trellis encoder performs Trellis encoding on the data stream using internal memories and resets the internal memories according to a control signal to control the Trellis resetting before the Trellis encoding is performed on the known data.
