Luma and chroma decoding using a common predictor

摘要

There are provided video encoders, video decoders, and corresponding methods. A video encoder for encoding video signal data for an image block includes an encoder for encoding all color components of the video signal data using a common predictor. A video decoder for decoding video signal data for an image block includes a decoder for decoding all color components of the video signal data using a common predictor. Additionally, an apparatus and method for encoding and decoding signal data for an image block includes an encoder and decoder for encoding/decoding color components of the video signal data without applying a residual color transform thereto. Furthermore, a video encoder and decoder for encoding/decoding video signal data for an image block includes an encoder and decoder for encoding/decoding the video signal data using unique predictors for each of color components of the video signal data.

1. An apparatus for decoding video signal data for an image block, the apparatus comprising a decoder for decoding color components of the video signal data without applying a residual color transform thereto, said decoder decodes all of the color components of the video signal data using a common color component predictor wherein sampling of the video signal data corresponds to a 4:4:4 format.
