Abstract:
1. An apparatus comprising: an encoder for encoding a block in a picture by performing a motion compensated temporal filtering (MCTF) prediction step for the block using a first weighting factor applied to a first reference picture, while using a different default update weighting factor applied to a second reference picture for a corresponding MCTF update step for the block, wherein said encoder selectively encodes the block in the picture by alternatively or concurrently performing the MCTF prediction step for the block using the first weighting factor applied to the first reference picture, while using a default update weighting factor applied to the second reference picture for the corresponding MCTF update step for the block, wherein the default update weighting factor incorporates a weighting factor derived from the first weighting factor applied to the first reference picture for the MCTF prediction step for the block.
