Abstract

En un ejemplo, un método para codificar datos de video incluye determinar, por un codificador de video y para un bloque de datos de video, una gama de colores que tiene una pluralidad de entradas que indican una pluralidad de valores de color respectivos, en donde una primera línea del bloque de datos de video incluye un píxel situado adyacente a un borde del bloque de datos de video, y en donde una segunda línea del bloque de datos de video incluye un píxel situado adyacente al borde del bloque y adyacente al píxel de la primera línea. En este ejemplo, el método también incluye codificar, en un orden de escaneo, valores índices que mapean píxeles del bloque en entradas en la gama de colores, en donde el píxel de la segunda línea sigue inmediatamente el píxel de la primera línea en el orden de escaneo.
