Patent ID: 8386896

Claim:
A receiver for 8VSB digital television signals that convey robust data subjected to parallel concatenated convolutional coding (PCCC) before being further coded by 2/3 trellis coding of said 8VSB digital television signals, said receiver comprising: apparatus for converting a selected 8VSB digital television signal received as an amplitude-modulated radio-frequency carrier to a baseband digital television signal, which apparatus includes front-end circuitry, an analog-to-digital converter, a demodulator for 8VSB digital television signals and a channel equalization filter; a 12-phase trellis decoder connected for providing trellis decoding results that include soft decisions concerning symbols in said baseband digital television signal, said 12-phase trellis decoder connected to receive the baseband digital television signal from said apparatus for converting a selected 8VSB digital television signal received as an amplitude-modulated radio-frequency carrier to a baseband digital television signal; and further apparatus connected for decoding selected portions of said trellis decoding results conveying said PCCC that encodes said robust data, thus to reproduce said robust data.
