Methods and devices for re-synchronizing a damaged video stream

摘要

The invention concerns methods and devices for concealing artefacts induced by transmission errors in a video sequence transmitted over a network between a server and a client making it possible to avoid abrupt resynchronization following a transmission error. When an error is detected, a video stream is created from a first video stream not containing any error and data representing artefacts induced by that error. The influence of the data representing the artefacts diminishes with time such that the created video stream converges towards the video stream not containing any error. The creation of the video stream in which the effects due to a transmission error are progressively removed may be carried out by the server or by the client.
