The embodiment of the invention provides a channel switching method and a channel switching device. The method comprises the following steps of: acquiring control information for switching a channel, wherein the control information comprises a channel identifier and a preset time; and switching the channel to the channel corresponding to the channel identifier at the preset time. The embodiment of the invention acquires the control information for switching the channel, switches the channel to the channel corresponding to the channel identifier in the control information at the preset time in the control information and starts playing a currently corresponding program; and a set-top box performs channel switching according to the channel, so the set-top box is not required to perform a preset operation on the same program selected by a user, reduce the channel switching complexity and improve the channel switching efficiency.
Description
technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a channel switching method and device. Background technique [0002] The current digital TV includes digital TV based on coaxial cable, satellite, terrestrial transmission and other access methods or IP digital TV based on Internet Protocol (Internet Protocol). The set-top box provides users with electronic program guide (EPG ), so that the program selected by the user can be scheduled according to the EPG, and when the broadcast time of the scheduled program is reached, switch to the channel corresponding to the scheduled program and play the scheduled program. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: since the set-top box switches channels according to the program, that is, the program is used as the predetermined unit, even if the program that the user w...
