Methods and apparatus for encoding and decoding multimedia frames are presented. The method comprises encoding a set of acquisition frames including a viewable frame, each frame comprising one or more intra-coded portions and one or more inter-coded portions, wherein the act of encoding the intra-coded portions comprises positioning the intra-coded portions such that when the intra-coded portions of the set of acquisition frames are combined, a complete intra-coded composite frame is formed. The act of encoding the inter-coded portions comprises predicting the inter-coded portions such that the viewable frame is comprised of intra-coded portions and inter-coded portions that are directly or indirectly predicted from the intra-coded portions of the set of acquisition frames.
L'invention concerne des procédés et des dispositifs pour le codage et le décodage de trames multimédia. On procède comme suit : codage d'une série de trames d'acquisition comprenant une trame visualisable, chaque trame comportant une ou plusieurs parties à intracodage et une ou plusieurs parties à intercodage, sachant que le codage des parties à intracodage amène à positionner celles-ci de sorte que, lorsque les parties à intracodage de la série de trames d'acquisition sont combinées, on établisse une trame composite à intracodage. Le codage des parties à intercodage consiste à prévoir les parties à intercodage de sorte que la trame visualisable comporte des parties à intracodage et des parties à intercodage prévues directement ou indirectement à partir des parties à intracodage de la série de trames d'acquisition.
