Abstract

DC60 The invention herein is to provide a video encoder, decoder. corresponding video and method Video encoders for encoding video signals to An image block contains an encoder (100) for encoding every color component of the data. Video signal using a common predictor (315) Video signal decoder for decoding the data. The video signal provided with every block of image will consist of a decoder (200) for decoding. color components of video signal data using a common predictor (430). The method for encrypting and decoding the signal data to the image block consists of an encoder. and a decoder for encoding/decoding the color components of video signal data without residual color conversion. Video encoders and decoders for encoding/decoding video signals to image blocks consist of encoders and decoders. For encoding/decoding video signal data using unique predictors unique to each The color component of the video signal data.
