Abstract

Innovaciones en el uso de modo de mapa de índice de color base ("BCIM") durante codificación y/o descodificación simplifican implementación al reducir el número de modificaciones hechas para soportar el modo de BCIM y/o mejorar la eficiencia de codificación del modo de BCIM. Por ejemplo, algunas de las innovaciones involucran reutilización de una estructura de sintaxis que se adapta para coeficientes de transformación en lugar de datos de señal para elementos de un mapa de índice en el modo de BCIM. Otras innovaciones se refieren a asignación de valores de índice en modo de BCIM o predicción de elementos en un mapa de índice en el modo de BCIM. Incluso otras innovaciones se refieren al manejo de valores de excepción en el modo de BCIM.
