METHODS, DECODER AND ENCODER FOR MANAGING VIDEO SEQUENCES

摘要

Methods, decoders, and encoders are disclosed for managing a video sequence while using at least a number of processing cores. The video sequence represents a picture. The picture comprises a number of partitions, which are independent from each other with respect to decoding of the picture. The decoder or the encoder estimates a set of values, wherein each value of the set corresponds to a corresponding partition of the number of partitions, and wherein each value relates to decoding time of its corresponding partition. The decoder decodes or the encoder encodes the number of partitions based on the decoding time as given by the set of values, while using the number of processing cores, at least initially, in parallel. Moreover, corresponding computer programs and computer program products are disclosed.

1. A method, performed by a decoder comprising multiple processing cores enabling parallel decoding, for managing a coded video sequence while using at least a number of processing cores of the decoder, wherein the coded video sequence represents a picture, wherein the picture comprises a number of partitions, which are independent from each other with respect to decoding of the picture, wherein the method comprises:
estimating a set of values, wherein each value of the set corresponds to a corresponding partition of the number of partitions, wherein each value relates to decoding time of its corresponding partition; and decoding the number of partitions based on the decoding time as given by the set of values, wherein the decoding is performed by using the number of processing cores, at least initially, in parallel, wherein the number of processing cores is less than the number of partitions, and the number of processing cores is greater than one.
