Abstract

Se describen sistemas, métodos y aparatos para procesamiento de video, que incluyen predicción ponderada para bloques de video. Un método ejemplar incluye realizar una conversión, de acuerdo con una regla, entre un corte 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 se incluye un tercer elemento de sintaxis en el flujo de bits, y en donde el primer elemento de sintaxis indica si está habilitada una predicción ponderada para cortes bidireccionales de imágenes codificadas que hace referencia al PPS, el segundo elemento de sintaxis indica si la información relacionada con la predicción ponderada está presente en los encabezados de imagen o encabezados de corte de imágenes codificadas que hacen referencia al PPS, y el tercer elemento de sintaxis indica un número de pesos asociados con una lista 1 de imágenes de referencia del corte actual.
