Abstract

Se describe un aparato que incluye un codificador. El codificador recibe datos de imagen o video, codifica los datos de imagen o video recibidos y proporciona un flujo de bits que representa los datos de imagen o video. El codificador incluye un codificador de CABAC. El codificador de CABAC recibe un elemento de sintaxis con valor binario asociado con un bloque de los datos de imagen o video que se van a codificar, y codifica, utilizando un modelo de contexto seleccionado, el elemento de sintaxis con valor binario en bits codificados para el flujo de bits. El elemento de sintaxis con valor binario incluye un indicador de herramienta que indica si se emplea o no cierta herramienta de codificación, como una intra-predicción ponderada lineal, LWIP, cuando se codifica un bloque de los datos de imagen o video. Para un bloque de los datos de imagen o video que tiene una relación de aspecto más grande que 2 y al que se puede aplicar la cierta herramienta de codificación, un primer modelo de contexto para codificar el indicador de herramienta se selecciona de un grupo de uno o más primeros modelos de contexto, y para un bloque de los datos de imagen o video que tiene una relación de aspecto menor que o igual a 2 y al que se puede aplicar la cierta herramienta de codificación, un segundo modelo de contexto para codificar el indicador de herramienta se selecciona de un grupo de uno o más segundos modelos de contexto.
