The present invention relates to the field of network technologies, and discloses a method and an apparatus for synchronizing video live broadcast, which can improve user experience in a video live broadcast service. In the present invention, a video stream synchronization request is sent to a network side device; a video stream playback position synchronization parameter sent by the network side device is received, where the video stream playback position synchronization parameter includes a playback position parameter at a video stream sending moment and a system frame number SFN at the video stream sending moment; an SFN at a video stream receiving moment is acquired; and the playback position parameter at the video stream sending moment is adjusted according to the SFN at the video stream sending moment and the SFN at the video stream receiving moment, so as to coincide with a current playback position parameter of the network side device. Solutions provided in embodiments of the present invention are applicable to synchronizing network video live broadcast.
