Abstract
Se describen sistemas, métodos y aparatos para procesamiento de video, que incluyen predicción pesada para bloques de video. Un método de ejemplo incluye llevar a cabo una conversión, de acuerdo a una regla, entre un segmento actual de una imagen actual de un video y un flujo de bits del video, en donde la regla especifica que un primer elemento de sintaxis de un conjunto de parámetros de imagen (PPS) y un segundo elemento de sintaxis del PPS controlan si un tercer elemento de sintaxis está incluido en el flujo de bits, y en donde el primer elemento de sintaxis indica si está habilitada una predicción pesada para segmentos bidireccionales de imágenes codificadas referidas al PPS, el segundo elemento de sintaxis indica si está presente información relacionada con la predicción pesada en cabeceras de imagen o cabeceras de segmento de imágenes codificadas referidas al PPS, y el tercer elemento de sintaxis indica un número de pesos asociados con una lista 1 de imágenes de referencia del segmento actual.
