Abstract:
1. A digital television receiver comprising: a demodulator being coupled to an antenna for generating a synchronization clock and a demodulated signal according to a digital television signal received from the antenna; a first switch having one end being coupled to a bypass signal from another receiver for selectively coupling the bypass signal to a first node or a second node; a signal combiner being coupled to the demodulator and the first node for combining the demodulated signal and the bypass signal when the first switch is coupling the bypass signal to the first node, and for passing the demodulated signal when the first switch is not coupling the bypass signal to the first node to thereby form a combined signal; a channel decoder being coupled to the signal combiner for generating transport stream packets according to the combined signal; a smooth buffer being coupled to the channel decoder and the demodulator for generating a smoothed transport stream having packets being uniformly spaced according to the transport stream packets generated by the channel decoder and the synchronization clock generated by the demodulator; and a second switch being coupled to the signal combiner, the smooth buffer, and the first switch for selectively coupling the combined signal, the smoothed transport stream, or the bypass signal to an output terminal of the digital television receiver.
