Dual-Tuner pre-frequency locking method based on intelligent gateway

Abstract

The present invention provides a dual-Tuner pre-frequency locking method based on an intelligent gateway. The method comprises the following steps: receiving a channel change instruction of a channel A; using a Tuner 1 to lock the frequency point PA of the channel A; after the locking is successful, solving a standard flow from the code stream on the frequency from the Tuner 1 through a demodulator (Demod); performing Demux data stream again, using a player to play the video; adapting a pre-frequency locking method for pre-frequency locking; using the Tuner 2 to lock the frequency point PB of a channel B which is most likely change the channel; receiving the channel changing instruction once again, wherein the channel change channel is the channel B; because the Tuner 2 had locked the frequency point PB of the channel B in advance, directly starting to use the Demod to solve the standard stream from the Tuner 2; performing the Demux data stream again, using the player to start video playing; adapting the pre-frequency locking method for pre-frequency locking; using the Tuner 1 to lock the frequency point PC of a channel C which is most likely change the channel; and repeating the same operation mentioned above when the subsequent channels are changed.
