Highly efficient coding apparatus producing encoded high resolution signals reproducible by a vtr intended for use with standard resolution signals

摘要: A highly efficient coding apparatus encodes high resolution digital video data so it can be decoded as either format or standard data. The is divided into blocks, and then sub-blocks of N picture elements, where the ratio to that format. Each sub-block elements averaged, averaged encoded via adaptive dynamic range (ADRC). difference between each its corresponding average value separately additional combined Also, ADRC recorded by a VTR reproduced provide signal having number although only image.
