Method and device for controlling channel-switching and non-transitory computer-readable storage medium for storing the method

Abstract

In a method for controlling channel-switching, a current channel is displayed through a display unit. A channel-switching correlation table is looked up to obtain at least one candidate channel, which is predicted to be watched after the current channel. The current channel is switched to the at least one candidate channel when a channel-switching signal is received, such that the display unit displays the at least one candidate channel. The present invention also discloses a device for controlling channel-switching and a non-transitory computer-readable storage medium for storing the method for controlling channel-switching.
