METHOD AND SYSTEM FOR VIDEO DISTRIBUTION

摘要

PROBLEM TO BE SOLVED: To reduce a sense of discomfort for a viewer in using a video-on-demand system by keeping a playback speed constant even in case of an increase in load on a client's CPU or load on a disk of a video server.

SOLUTION: The video server 101 sets an I-frame transmission time interval for maintaining an initially set playback speed and a seek time interval meaning a seek time up to a next I frame in a video file. If the actual I-frame transmission time interval becomes longer owing to an increase in load on the video server or client, the initial I-frame transmission time interval and seek time interval are corrected to maintain the specified playback speed.
