Abstract
A method of generating a smoothed transport stream to an MPEG decoder for a diversity combine digital television receiver includes generating a plurality of synchronization clocks and demodulated signals according to a plurality of digital television signals received from a plurality of antennas; monitoring a signal quality associated with each of the digital television signals; combining at least demodulated signals having a signal quality being greater than a predetermined threshold to thereby form a combined signal; generating transport stream packets according to the combined signal; selecting a synchronization signal corresponding to a digital television signal having a signal quality being greater than a second predetermined threshold as a selected synchronization signal; and generating a smoothed transport stream having packets being uniformly spaced according to the transport stream packets and the selected synchronization signal.
