Patent ID: 8111748

Claim:
A method for video coding, comprising: assigning different weights to at least two reference pictures situated in an arbitrary temporal position before or after at least one predicted picture of a picture sequence; and calculating the at least one predicted picture by weighted averaging of the at least two reference pictures; wherein said assigning comprises selecting the different weights based on respective reliability of the reference pictures for prediction, further comprising dividing the at least one predicted picture into at least two blocks, wherein said assigning includes forming weighting factors inversely based on quantization level width per block of quantizers used for coding of the reference pictures; wherein a block used for prediction simultaneously superposes a plurality of coded individual blocks in a respective reference picture, and wherein said assigning includes forming a weight of the block used for the prediction either from an inverse average value of the quantization level width of individual blocks or inversely with respect to a largest value of quantization levels.
