Title:
合成ビデオのためのロスレス・コード化および関連するシグナリング方法
Document Type and Number:
Japanese Patent JP5777080
Kind Code:
B2
Abstract:
An apparatus used in video encoding comprising a processor configured to receive a video frame, select at least one region in the video frame, bypass a quantization step in encoding of the at least one region, for a current block in the at least one region generate a prediction block, subtract the current block by the prediction block to generate a residual block, and selectively bypass a transform step in encoding of the residual block.
