CONVERSION BUFFER FOR DECOUPLING NORMATIVE AND IMPLEMENTATION DATA PATH INTERLEAVING OF VIDEO COEFFICIENT

摘要

A video coder conversion buffer for decoupling a normative coding order and a processing order for video coefficients for intra coding processing of such video coefficients as well as interleaving schemes for the processing order will be discussed. The interleaving schemes include the steps of: receiving a plurality of blocks of quantized residual transformation coefficients corresponding to a coding unit of a video frame in a normative coding order; Interleaving the plurality of blocks of quantized residual transformation coefficients for the normative coding order into a processing order; and performing inverse quantization, inverse transform and intra prediction operations on the plurality of quantized coefficient blocks in the processing order.
