METHOD AND APPARATUS FOR VIDEO-ON-DEMAND WITH FAST PLAY CAPABILITY |
摘要 |
A method and apparatus for processing a coded data stream of video information (e.g., video-on-demand) for selective display according to a Normal PLAY Mode or a Fast PLAY Mode, by splitting the coded data stream into (a) anchor data constituted of anchor picture frames (e.g., I-frames) coded without reference to other picture frames, and (b) complemental data (e.g., B-frames and P-frames) complementing the anchor data; storing the anchor data in an anchor data file and the complemental data in a complemental data file; upon the selection of a Normal PLAY Mode, combining the data of both the anchor data file and the complemental data file to recompose and display the video information; and upon the selection of a fast PLAY mode, displaying only the data of the anchor data file. |
