Abstract
SE DESCRIBEN TÉCNICAS PARA LA CODIFICACIÓN EN BASE A LA PALETA. EN LA CODIFICACIÓN EN BASE A LA PALETA, UN CODIFICADOR DE VIDEO PUEDE FORMAR UNA PALETA COMO UNA TABLA DE COLORES PARA REPRESENTAR DATOS DE VIDEO DE UN BLOQUE DADO. LA CODIFICACIÓN EN BASE A LA PALETA PUEDE SER ÚTIL PARA CODIFICAR BLOQUES DE DATOS DE VIDEO QUE TIENEN UNA CANTIDAD RELATIVAMENTE PEQUEÑA DE COLORES. EN LUGAR DE CODIFICAR LOS VALORES REALES DE P�XELES O SUS RESIDUALES PARA EL BLOQUE DADO, EL CODIFICADOR DE VIDEO PUEDE CODIFICAR VALORES DE �NDICES PARA UNO O M�S DE LOS P�XELES. LOS VALORES DE �NDICES ASIGNAN LOS PIXELES A ENTRADAS EN LA PALETA QUE REPRESENTAN LOS COLORES DE LOS PIXELES. SE DESCRIBEN TÉCNICAS PARA DETERMINAR SI DESHABILITAR EL FILTRADO, TALES COMO EL DESBLOQUEO DEL FILTRADO, O EL FILTRADO DE MUESTRA DE ADAPTACIÓN COMPENSADA (SAO), DE BLOQUES CODIFICADOS POR LA PALETA EN UN CODIFICADOR DE VIDEO O UN DECODIFICADOR DE VIDEO. ASIMISMO, SE DESCRIBEN TÉCNICAS PARA MODIFICAR UN TAMAÑO DE LA PALETA Y ENTRADAS DE PALETA DE UNA PALETA EN EL CODIFICADOR DE VIDEO EN BASE A LOS COSTOS DE LA TASA DE DISTORSIÓN
