Abstract:
1. A method of identifying data losses in a video sequence transmitted between a server and at least one client over a communication network, said video sequence comprising a plurality of video data network containers comprising video data, said video data being coded using hierarchical video coding employing a predetermined number of dependent hierarchical levels, said video data network containers being transmitted over said network via a series of data transport packets, the number of network containers transported by a data transport packet being random, said method of identifying data losses comprising: a step of detecting and locating errors, comprising detecting data losses and locating video data affected by said losses, said step of detecting and locating errors requiring no decoding of video data contained in said video data network containers and comprising: combining information coming from transport packets and information coming from video data network container headers; and deducing from the combined information the detection of said data losses and the location of the video data affected by said losses.
