Support fast scan operations with video streaming technology
Chun-Ming Huang, Kai-Chao Yang, Jia-Shung Wang · 2005
In this article, we present a novel approach to support fast scan operations for video streaming applications. Our approach is based upon reshaping the ordinary linear encoded GOP (group of pictures) structure into a hierarchically encoded binary tree, along with a proximity-based approximation scheme. Our scheme can support forward and backward fast playback operations at any speed-up factor with few bandwidth requirements even for the normal speed playback.
