Abstract
En un ejemplo, un método de codificación de datos de video incluye determinar, a través de un decodificador de video y para un bloque de datos de video, una paleta que tiene una pluralidad de entradas indicando una pluralidad de valores de color respectivos, en donde una primera línea del bloque de datos de video incluye un pixel ubicado junto a un borde del bloque de datos de video, y en donde una segunda línea del bloque de datos de video incluye un pixel ubicado junto al borde del bloque y junto al pixel de la primera línea; en este ejemplo, el método también incluye codificar, en un orden de exploración, valores de índice que mapean píxeles del bloque a entradas en la paleta, en donde el pixel de la segunda línea sigue inmediatamente al pixel de la primera línea en el orden de exploración.
