ABSTRACT:
Off-line computation and recording is applied (via an under-powered processor) to the encoding, for bandwidth compression, of a high-resolution video signal. This technique permits more compute cycles to be applied to each frame than if the process were attempted to be accomplished in real time. Better compression ratios and/or better visual quality are, thus, achieved than if the process were attempted to be performed by the same processor in a real-time manner.
