Abstract

The invention discloses a fast display method for a streaming media video-on-demand seek picture. The method comprises the following steps: video-on-demand on a video file is realized; key frames are extracted from the video file according to a certain time interval, and a series of zooming pictures is generated; the generated pictures are named based on the time stamps of the key frames; a key frame index array is built; the time stamp of a playing point is recorded in real time during a playing process; with the time stamp as reference, a requested picture is displayed below the video picture; the user selects a positioning time stamp to send see request data according to the displayed picture; the video data are transmitted to an intelligent television playing end starting from an offset position; and the intelligent television player starts playing from the key frames. In comparison with the prior art, through analyzing video materials at a streaming media server to generate usable thumbnails, playing details are appointed with the player end, a user can be helped to quickly seek a required video picture, the seeing time is saved, and the seeing quality is improved.
