Embodiment Construction

[0026]This disclosure describes a residual coding technique using vector quantization coding, which relies on template matching in the residual coding process. Residual coding refers to the coding of "residuals" generated by motion estimation and motion compensation, or spatial estimation and intra prediction. Motion estimation and motion compensation are well-known techniques used in many video coding standards, using temporal or inter-frame data correlation for inter-frame compression. The process of comparing the current video block to be encoded with various other video blocks from another frame is often referred to as motion estimation. The process of encoding the difference between the current video block and the predicted block includes a process called motion compensation. Motion compensation generally refers to the act of obtaining a predictive block using a motion vector and then subtracting the predictive block from the input block. The output of motion compensati...

Abstract

This disclosure describes residual coding techniques that use vector quantization coding, which relies on template matching. However, rather than transmit vector quantization codebook indexes (or codewords) that may have no meaning to standard compliant CODECs, the techniques described herein map the residual templates to pre-computed compressed residual blocks that are compliant with a video standard. The standard compliant compressed residual blocks can then be transmitted to another device, which complies with the standard. The techniques can exploit the advantages associated with vector quantization coding, such as the ability to perform more parallel processing, while still maintaining compliance with a video coding standard.

Description

technical field [0001] The present disclosure relates to digital video processing, and, more particularly, to coding techniques for creating standards-compliant compressed residual modules. Background technique [0002] Digital video capabilities are available in many devices, including digital television, digital direct broadcast systems, wireless communication devices, personal digital assistants (PDAs), portable computers, desktop computers, digital cameras, digital recording devices, cellular or satellite communication phones, and more. Digital video equipment can offer significant improvements over traditional analog video systems in creating, aligning, transmitting, storing, recording and playing back all motion video sequences. [0003] Many different video coding standards have been established for coding digital video sequences. For example, the Moving Picture Experts Group (MPEG) has developed numerous standards, including MPEG-1, MPEG-2, and MPEG-4. Other standa...
