Fast channel switching method and apparatus for digital broadcast receiver
A fast channel switching method and apparatus for a digital broadcast receiver that can reduce a channel switching delay caused by limitations in real time broadcasting systems is provided. A fast channel switching method of the present invention includes simultaneously receiving broadcast signals of a first service channel and a second service channel; presenting the broadcast signal of the first service channel through a player; and circular-buffering the broadcast signal of the second service channel. A digital broadcast receiver using a fast channel switching technique of the present invention can buffer an adjacent service channel while serving the current service channel such that the buffered broadcast signal is output when the adjacent channel is selected, thereby reducing a channel switching delay.
