Abstract
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.
