Title:
A DUAL PREDICTION VIDEO ENCODING AND DECODING METHOD AND A DEVICE
Document Type and Number:
WIPO Patent Application WO/2009/052697
Kind Code:
A1
Abstract:
A method of dual prediction video decoding, a method of dual prediction video encoding and the corresponding devices are provided. In the decoding method, the reconstructing process of decoding reconstructing image includes the process of dual prediction compensation and the process of the second prediction storage, wherein the process of dual prediction compensation includes the process of the first prediction compensation and the process of the second prediction compensation; The input of the second prediction compensation process includes the reconstructed of the first residual and the reconstructed of the second residual. The encoding method includes the process of dual prediction and the process of the second prediction storage, wherein the process of dual prediction includes the process of the first prediction and the process of the second prediction; The input of the second prediction process includes the first residual and the prediction value of the first residual; The encoding method generates the relevant code stream. The using of the said methods of dual prediction video decoding and encoding and the devices can eliminate the redundancy, and improve the encoding performance.
