Method for coding a subsequent sequence of pictures by help of a preceding sequence of pictures

摘要

The invention is related to a method and an encoder for coding a subsequent sequence of pictures (GOP) by help of a preceding sequence of pictures (GOP). Said method comprises the step of determining picture dependent coding parameters from coding of the pictures in the preceding group (GOP). The method further comprises the step of determining complexities by help of the determined coding parameters. As well, the method comprises the step of updating enhanced level weighting factors by help of the determined complexities and the step of coding of pictures of the subsequent group (GOP) by help of the updated enhanced level weighting factors. By updating the enhanced level weighting factors by help of the complexities coding performance is improved and smoothing of quality transition from a preceding group of pictures (GOP) to a subsequent group of pictures (GOP) is achieved.
