[0031] figure 1 A schematic diagram of the encoding method according to the invention is shown.
[0032] During a first step 1 of the complete encoding of an image performed in a conventional manner, a source sequence transmitted to the input of an encoding device implementing the method is processed. This encoding step provides at its output an encoded binary sequence consisting of video packets defined by synchronization flags which is passed on to the next step 2 . It also transmits to this step 2 and step 4 locally coded images. From the encoded data, during encoding step 1, the image is reconstructed in a known manner. For encoding modes that use temporal prediction, such as inter-image, it is used as a reference image during encoding.
[0033] The effect of step 2 is to remove video packets from the data stream and calculate the corresponding images. The picture, referred to as a degraded locally decoded picture, is obtained from a locally decoded picture from which ...
