TH148943B - Encoding quantization parameters (qp) in video encoding - Google Patents

Abstract

The method of encoding delta quantization parameters has been described in one example. A video decoder may accept delta-type quantization parameters (decqp) for blocking Current quantization of the video information. Where DQP values are accepted, regardless of the coefficient of Convert to zero in the current quantization block or not. In another example, a video decoder may obtain the decoder for the current quantization block of the video data in case the character Predict the QP for the current quantization block only zero. And infer the DQP value as the center If the QP predictor for the current quantization block is non-zero. And there will be no coefficients Non-zero conversion in the current quantization block.
