Abstract

En una implementación particular, un decodificador de video puede refinar un predictor de vector de movimiento inicial decodificado del flujo de bits para un bloque actual. Para reducir la sobrecarga de señalización, el decodificador puede determinar si el refinamiento de movimiento se utiliza o no con base en la información que ya está disponible, por ejemplo, con base en si el campo de movimiento es uniforme alrededor del bloque actual y si hay un cierto nivel de texturas en los bloques adyacentes. La diferencia de vector de movimiento decodificada del flujo de bits puede utilizarse para activar o desactivar automáticamente el refinamiento de movimiento sin recibir señalización explícita en el flujo de bits. Por ejemplo, cuando la diferencia de vector de movimiento es menor que un umbral, el refinamiento de movimiento se activa automáticamente, y cuando la diferencia de vector de movimiento es mayor que otro umbral, el refinamiento de movimiento se desactiva automáticamente. Un codificador de video correspondiente puede elegir si o no utilizar y señalar el refinamiento de movimiento con base en las decisiones del codificador.
