The picture and coding method comprises the following steps: coding of the lowest resolution picture to provide coded data for a base layer of the coded data flow, zoom of the picture to obtain a low resolution zoomed picture of dimensions of those of the picture for the common video part, coding of to supply coded data to an upper layer of the coded data flow and using at least one of the following modes: predictive inter layer coding using a previous low resolution zoomed picture in which a predicted block and a motion vector defining this block is determined, predictive inter layer coding using a current low resolution zoomed picture in which a predicted block and a motion vector defining this block is determined.
Hierarchical coding method of different non-proportional formats to give a flow of coded data, a first picture in format F1 and a second picture in format F2 of a lower resolution to the first format F1, the video content of the images and having at least one common part, wherein it implements the following steps:
Method for decoding a flow of digital data structured into at least one base layer comprising data relative to a low resolution image and an upper layer comprising data relating to a high resolution picture, the low resolution picture corresponding to at least a video part of the high resolution picture comprising the following steps:
