Title: VIDEO CODING WITH DELAYED RECONSTRUCTION
Abstract:
Methods of encoding and decoding media, for example video, using delayed reconstruction are described. The decoding process may include decoding first prediction information that specifies parameters for generating a prediction of a current block, and residual data syntax elements for the current block, and decoding second prediction information that specifies parameters for a prediction of a subsequent block. The decoder reconstructs residuals for the current block based upon the residual data syntax elements and the second prediction information. It then generates the prediction of the current block from the first prediction information and stored reconstructed data, and reconstructs the current block by adding the reconstructed residuals to the prediction of the current block.
