Abstract:
The reception method is implemented in a receiver apparatus receiving images of a video sequence having undergone losses during an exchange of data with a sender apparatus connected to said receiver apparatus via a communication network. The receiver apparatus comprises at least a first module implementing a transport layer and a second module implementing an application layer, the application layer being subdivided into a first sub-module implementing the decoding of the video and a second sub-module implementing the display of said video. The method comprises the following steps: in the transport layer, transmitting a data loss detection signal intended for the application layer, as soon as the transport layer detects a loss of data; and in the application layer, implementing a loss concealment mechanism, on reception of said loss detection signal and without waiting for said application layer itself to detect said data loss so detected.
