A water ring scanning apparatus and method, and an apparatus and method for encoding/decoding video sequences using the same are disclosed. A water ring scanning apparatus includes: a preferential scan unit for scanning information on a water ring origin point (water-ring (0)) in an image frame, which is a most significant bit of the image frame to be preferentially scanned; a scan location decision unit for deciding a location of i-th generated water ring (water-ring(i)), which is a rectangular-shape ring surrounding the water ring origin point; and a scan unit for scanning information on the location of the i-th generated water ring.

L'invention concerne un appareil et procédé de balayage à anneau liquide ainsi qu'un appareil et un procédé permettant de coder/décoder des séquences vidéo au moyen dudit appareil et dudit procédé de balayage à anneau liquide. Un appareil de balayage à anneau liquide comporte : une unité de balayage préférentiel permettant de balayer des informations sur un point d'origine de l'anneau liquide (water_ring (0)) dans une trame d'image, ledit point d'origine étant un bit significatif de ladite trame d'image devant être balayé de manière préférentielle ; une unité de décision de l'emplacement de balayage permettant de décider l'emplacement du ième anneau liquide généré (water_ring (i)), qui est de forme rectangulaire et qui entoure le point d'origine de l'anneau liquide ; et une unité de balayage permettant de balayer des informations concernant l'emplacement du ième anneau liquide généré.
