Abstract

Un sistema y método mejorado para proveer prediccion intercapa mejorada para escalabilidad espacial extendida en codificacion de vídeo, como así también mejorar la prediccion intercapa para los vectores de movimiento en el caso de la escalabilidad espacial extendida. En varias realizaciones, para la prediccion del modo del macrobloque, el índice de cuadro de referencia real y los vectores de movimiento de la capa base se utilizan para determinar si dos bloques deben ser fusionados. Además, los multiples pixeles representativos en un bloque 4x4 se pueden utilizar para representar cada bloque 4x4 en un macrobloque de capa base virtual. La informacion de division y del vector de movimiento para el bloque relevante en el macrobloque de capa base virtual puede derivar de toda la informacion de division y de los vectores de movimiento de aquellos bloques 4x4.
