SYSTEM AND METHOD FOR ONLINE MEDIA PREVIEW

摘要

An embodiment of a system and method for online media preview extracts a plurality of preview frames from a media file. The preview frames are saved in a layered data structure. In addition, the preview frames may be scaled to a lower resolution so that the preview file formed by the preview frames is reduced in size. After receiving a preview request, a delivery scheduling scheme delivers the preview frames at selected time points to minimize startup delay and playback jitter.
