Abstract:
An encoding system, comprising:a pre-processor, for receiving and processing a plurality of information frames to produce a plurality of pre-processed information frames, said pre-processor identifying and generating an indicium of an inter-frame information discontinuity within said plurality of information frames, said pre-processor removing redundant frames from said plurality of information frames; an encoder, for encoding each of said plurality of pre-processed information frames substantially in accordance with a group of frames (GOF) information structure; and a controller, for adapting said GOF information structure in response to said indicium of said inter-frame information discontinuity within said plurality of information frames, and for adapting a bit allocation level associated with said GOF information structure, in response to removal of redundant frames within said plurality of information frames wherein: said pre-processor measures at least one of a spatial noise parameter and a temporal noise parameter of said plurality of information frames; said pre-processor, in response to said spatial noise parameter exceeding a spatial noise threshold level, imparts a spatial smoothing function to one or more of said plurality of information frames; and said pre-processor, in response to said temporal noise parameter exceeding a temporal noise threshold level, imparts a temporal smoothing function to one or more of said plurality of information frames.
