Abstract:
A method for color blending prevention in video coding may include selecting, in a mode decision phase of an encoding of a current video frame, to encode an output bitstream in skip mode, wherein the skip mode includes altering encoding of the coding unit by setting luma component transform coefficients for the coding unit to zero, revaluating the selection of the skip mode based on quantized chroma coefficients, the quantized chroma coefficients generated from transformed and quantized residual chroma components, confirming the selection of the skip mode when there are no non-zero quantized chroma coefficients, and revoking the selection of the skip mode when there are non-zero quantized chroma coefficients, wherein the non-zero quantized chroma coefficients are transmitted when the selection of the skip mode is revoked.
