Embodiments of the present disclosure disclose a channel change method and a related apparatus. The channel change method includes: receiving a live stream of a first channel, where the live stream of the first channel includes N media file sets; separately encoding the live stream of the first channel in different coding manners, to generate both a main stream and a sub stream; and generating a playlist of the first channel according to channel information of the first channel, coding information of the main stream, and coding information of the sub stream. The playlist instructs the client to perform channel change according to the main stream and the sub stream in response to that a client sends a channel change instruction.
