Method and device for determining the value of a delay to be applied between sending a first dataset and sending a second dataset

摘要

The invention relates to a method and to a device for determining the value of a delay to be applied between sending a first dataset and sending a second dataset, the data being representative of a sequence of coded images, the datasets consisting of data subsets, the coded images being coded according to a first level of resolution and at least a second level of resolution higher than the first level of resolution, the data subsets containing data of a first level of resolution. According to the invention:
first and second datasets are obtained (E506); andthe value of the delay is determined (E507), the value of the delay being dependent on the number of decoded images that can be formed from the data subsets of the first dataset which contain data of the second or of a second level of resolution.

1. A method implemented by a device for determining a value of a delay to be applied between sending a first dataset and sending a second dataset, from a sender device to a receiver device over a network, the method comprising:
obtaining the first and second datasets, the first and second datasets containing data corresponding to data subsets, which data is representative of a sequence of coded images, the coded images being coded according to a first level of resolution and at least a second level of resolution higher than the first level of resolution, the data subsets containing data of a single level of resolution; and determining the value of the delay to be applied between sending of the first and second datasets, from the sender device to the receiver device over the network, the value of the delay being dependent on a number of decoded images that can be formed from the data subsets of the first dataset, which data subsets contain data of the second level of resolution, wherein the value of the delay between sending of the first and second datasets, from the sender device to the receiver device over the network, is a minimum if the first data subset included in the second dataset contributes to formation of a same decoded image as the first data subset included in the first dataset.
