Abstract

The invention relates to a multimedia play method for switching from a first channel to a second channel and a multimedia play device. The multimedia play method for switching from the first channel to the second channel comprises the steps that when a player receives a complete frame of a multimedia code stream of the second channel, the player sends a stop command to a decoder, and the decoder stops transmitting a video code stream in a multimedia code stream of the first channel to the player. With the adoption of the multimedia play method and the multimedia play device, the blank screen duration time during channel switching can be shortened significantly, so that a watching feel of a video watcher can be raised.
