wherein the time information of each channel is an information according to at least one of a viewing time of the image of the each channel displayed on a screen and a non-viewing time of the each channel, and
wherein in the controlling the record progress state, if the channel is changed to a channel previous to a channel change after a lapse of a threshold time from the channel change, an image of the channel previous to the channel change which is recorded from a channel change time point is displayed, and an image received in real time through the channel previous to the channel change is recorded.
14. The image recording method of claim 13 , wherein in the controlling the record progress state, if the channel is changed to the channel previous to a channel change after the lapse of a threshold time from the channel change, a user is inquired whether to apply a time shift to the image of the channel previous to the channel change which is recorded from the channel change time point.
