Abstract

Se describen técnicas donde un dispositivo que incluye un decodificador de video emite información que identifica una imagen a un dispositivo que incluye un codificador de video. El codificador de video puede determinar imágenes que podrían haber sido utilizadas para codificar por inter-predicción la imagen y/o imágenes identificadas que siguen a la imagen identificada en orden de codificación. El codificador de video puede codificar por inter-predicción una imagen actual, con base en una o más de las imágenes determinadas y/o la imagen identificada.
