A METHOD FOR FAST FORWARD AND FAST BACKWARD PLAYING VIDEO DATA AND STREAM MEDIA SERVER

摘要

A method for fast forward and fast backward playing video data includes: obtaining video data for fast forward and fast backward playing it at different time speed from the original media file; generating the fast forward and fast backward sequence file and the fast forward and fast backward sequence index file using said video data; receiving the fast forward and fast backward playing request from a client-side, and obtaining the fast forward and fast backward index information meeting said playing request from said fast forward and fast backward sequence index file; and obtaining video data meeting said playing request from said fast forward and fast backward sequence file according to said index information, and transmitting it to said client-side through a network. A stream media server is disclosed. Using said method and stream media server, the efficiency for reading the fast forward and fast backward video data of the stream media server is improved.
