Patent

CA 2199946

A digital color video signal is subsampled into a special YUV block format that arranges the data in small groupings of interleaved V, U and Y values in a left-to-right, top-to-bottom sequence across a video frame. This format results in significantly-reduced hardware memory requirements in the video reception system. Interpolation or dithering is also used to reduce unwanted artifacts in the resulting images.

Un signal vidéo couleur numérique est sous-échantillonné pour donner un format de bloc YUV spécial qui ordonne les données en petits groupements de valeurs V, U et Y imbriquées dans une séquence de gauche à droite et de haut en bas sur une image vidéo. Ce format se traduit par un encombrement en mémoire matériel notablement réduit dans le système de réception vidéo. L'interpolation ou la juxtaposition est également utilisée pour réduire les artefacts dans les images résultantes.
