Abstract
A method and system for processing digital video is described. The invention permits fast forwarding, rewinding, pausing and resuming a digital video that is delivered over a computer network. In various embodiments of the invention, reduced-information frames (e.g., P-frames and B-frames) are skipped, samplings of complete frames (e.g., I-frames) are transmitted, and delay predictions are made to compensate for the lag time to enhance pause/resume functionality. The invention can be used delivering digital video in a low bandwidth environment. Moreover, the invention can be used in conjunction with any video standard in which there are a mix of full frames and reduced-information frames.
