The invented method makes audio/video stream broadcasted from broadcasting server possible to pass through routers and to transfer to another network segment for broadcasting, without need of any additional configuring routers. Broadcasting server uses user datagram protocol (UDP) to realize local audio/video stream broadcast. But usually, UDP cannot pass routers to transfer data to another network segment. Thus, the initiative broadcast is changed to passive request. Using transfer control protocol (TCP) relay through routers requests the data provided by broadcasting server so as to realize remote direct broadcasting audio/video stream. The technique integrates the direct broadcasting with video on demand (VOD), and the video server as the relay. When VOD client end requests direct broadcasting, the video server makes judgment and requests data from broadcasting server, then sends data to client end.

The invention discloses a video-on-demand method, which strengthens the participation of users and brings entirely new interaction experience. The technical proposal of the video-on-demand method comprises that the video-on-demand method comprises the following steps: a browser initiates a video-on-demand request, and provides a set-top box with a program number and a subsequent processing page after the playing of a program is finished; the set-top box orders a video from a video server according to the program number and directly switches towards the subsequent processing page after the playing is finished; and the subsequent processing page is provided with nodes which decide the trend of different programs, receives one node selected by a user, plays the content to which the node points, provides next subsequent processing page after the playing is finished, and repeatedly executes the previous step until the terminal of the program is reached or the user terminates the playing. The video-on-demand method is applied in the field of digital television.

The invention discloses a video starting acceleration method and device, a storage medium, a terminal and a server. The method comprises the following steps of when monitoring that a preset video event is triggered, sending a video list request and a video coding format parameter to a first server; receiving a video list obtained by the first server based on the video list request and the detailed information of each video in the video list obtained based on the video coding format parameter; and when a playing instruction of the target video is detected, playing the target video according to the detailed information of the target video. According to the technical scheme provided by the embodiment of the invention, when the preset video event is triggered, by requesting the first server to execute the detailed information of the video and the obtaining operation of the video list, the problem of longer first frame time caused by the fact that the terminal requests the detailed information of the video from the video server every time when the video playing instruction is detected, can be avoided, and the time required by clicking to play the first frame image of the video can be effectively shortened.

The invention discloses a time synchronization method. An agent module in the client acquires video file data from a video data server according to a video playback request of a video live APP, the video file data returned by the video data server are then received, the time information carried in the video file data is analyzed, and the time information and the video file data are synchronously transmitted to the video live APP. As the video file data carry the time information inserted by the video data server and the time information is consistent with the current time of the video data server, the scheme can reduce the time error between the client providing the video live service and the video server on the premise when the server does not need to perform additional interaction with the client, the time display accuracy in the client is improved, and better use experience is provided for the user.
