Abstract:
1. A digital broadcasting receiver comprising: an equalizer for receiving a transport stream (TS) comprising additional data and normal data, and equalizing the received TS; a decoder comprising a trellis decoder for trellis decoding the equalized additional data, a deinterleaver for deinterleaving the equalized additional data, an interleaver for interleaving the equalized additional data, and a convolutional decoder for convolutional decoding the equalized additional data without convolutional decoding the normal; wherein the additional data is RS-encoded and trellis encoded after being convolutional-encoded and interleaved in a digital broadcasting transmitter, wherein the decoder outputs the decoded additional data to a Reed Solomon (RS) decoder to perform RS decoding of the additional data, and wherein the trellis decoder and the convolutional decoder exchange decoding reliability information with each other.
