Embodiment
With reference to figure 1, the Play System that the present invention relates to comprises video acquisition end, network, user terminal player.Wherein, the video acquisition end is responsible for video acquisition, coding, compression, access network; The user terminal player can be portable terminal, PC, dull and stereotyped player, or is embedded in the broadcast instrument etc. of web browser.
Below in conjunction with accompanying drawing, a preferred embodiment of the present invention scheme is described.
With reference to figure 2, for present embodiment describe convenient, suppose the video acquisition end with the speed acquisition of K frame/second (30 frame/second) 30 minutes video, this video should comprise 54000 frames so.Adopt conventional art, with 30 frames/second broadcasting speed, then also only needs just can finish in 30 minutes.
The user terminal player be provided with and with per 5 minutes as time quantum; Then the user terminal player circulates successively with the per 5 minutes time quantums as a broadcast and carries out three broadcast stages.
With reference to figure 3, be very first time unit, the video structure of user terminal player plays; In this time quantum, the user terminal player is at first play with the speed of T frame/second (i.e. 25 frame/seconds).In these 5 minutes, player can only be play 7500 frames, is 5 minutes video with respect to the duration that is encoded to K frame/second, with the residue that produces 1500 frames.The user terminal player is with this 1500 frame (promptly the metadata cache of the 7501st frame to the 9000 frames is in the buffer area of player); This stage forms the stage for the alternate video data.
With reference to figure 4, at second time quantum, the user terminal player is at first play with the speed of K frame/second (i.e. 30 frame/seconds).In these 5 minutes, player can always will produce the residue of 1500 frames (the 16501st frame to the 18000 frames) by normal speed forward 9000 frames (i.e. the 7501st frame to the 16500 frames).The user terminal player with the metadata cache of this 1500 frame (i.e. the 16501st frame to the 18000 frames) in the buffer area of player.This stage is alternate video data continuation phase.
