Abstract

A switching device determines a video parameter value of a switching point of a first video stream, and determines a video parameter value of a switching point of a second video stream. The video parameter value includes a timestamp and/or a sequence number. The switching device determines an audio parameter value of a switching point of a first audio stream based on a timestamp of the switching point of the first video stream, and determines an audio parameter value of a switching point of a second audio stream based on a timestamp of the switching point of the second video stream. The audio parameter value includes a timestamp and/or a sequence number. The switching device performs switching based on determined switching points.
