摘要：
A digital television system includes a first tuner and first decoder for tuning to and decoding a selected digital television signal. A second tuner and second decoder are included for tuning to and decoding a separate digital television signal containing mosaic views of the receivable television signals. Upon a channel change command, first tuner is tuned to the new channel. Simultaneously, the output from the second decoder corresponding to the new channel is applied to the display. As such, the new channel is available for immediate viewing without waiting during the typical decoder delay.
