Abstract
Faster channel change time in ATSC such as ATSC 3.0 is effected by using the native tuner of a display device to present a currently demanded channel and a second tuner, which can be dongle-based, to tune/scan preemptively in the background based upon heuristics such as usage pattern of the user. If the user is pressing channel-up key using a remote control, the second tuner can be scanning and tuning the next channel in the channel map to preemptively tune to a second channel likely to be desired by the user for immediate presentation of that channel through the second tuner.
