Abstract

El modo de copia de boceto puede ser utilizado para codificar bloques que comprenden líneas irregulares, se puede eliminar la redundancia de sintaxis de los bloques con características especiales, y/o se puede simplificar la codificación del valor de ejecución. Se pueden eliminar las dependencias de análisis en el diseño de codificación de paleta. La dependencia del modelado de contexto del elemento de sintaxis paleta transpuesta indicador se puede eliminar, por ejemplo, utilizando codificación de longitud de ejecución sin utilizar contexto. Se pueden eliminar las dependencias del análisis de sintaxis y/o las dependencias de señalización de sintaxis que están relacionadas con señalización de color de escape. Un proceso de generación de tabla de paleta puede manejar el video de contenido de pantalla de entrada con altas profundidades de bit, por ejemplo, en el lado del codificador.
