Efficient support for interactive scanning operations in MPEG-based video-on-demand systems

摘要

In this paper, we present an efficient approach for supporting fast-scanning (FS) operations in MPEG-based video-on-demand(VOD) systems. This approach is based on storing multiple, differently encoded versions of the same movie at the server. A normal version is used for normal playback, while several scan versions are used for FS. Each scan version supports forward and backward FS at a given speedup.
