Abstract:
1. An integrated circuit device, coupled to a signal source that receives a broadcast spectrum from an electrically or optically conductive medium, to output formatted video signals corresponding to a selected channel which is one of a plurality of channels of the broadcast spectrum, the integrated circuit device comprising: tuner circuitry, coupled to the signal source, to receive a broadcast-frequency analog video signal, having timing information embedded therein, and to output a baseband video signal which corresponds to the selected channel of the broadcast spectrum, the tuner circuitry including: video decoder circuitry, coupled to the receiver circuitry, to receive the baseband video signal and output the first formatted video signal corresponding to the selected channel of the broadcast spectrum, the video decoder circuitry including: timing recovery circuitry, coupled to the tuner circuitry, to generate a timing signal using the timing information within the broadcast-frequency analog video signal, the timing recovery circuitry is configured to provide the timing signal to the cancellation circuitry; and format circuitry, coupled to the processing circuitry, to generate and output the formatted video signal, corresponding to the selected channel, using the third signal, fourth signal and timing signal.
