Abstract

Se describe un mecanismo de codificación de video. El mecanismo incluye recibir un flujo de bits que comprende una imagen actual que incluye una subimagen codificada de acuerdo con la interpredicción. Se determina un vector de movimiento para un bloque de la subimagen. Se aplica una función de recorte a ubicaciones de muestra en un bloque de referencia para soportar la aplicación de un filtro de interpolación cuando el vector de movimiento apunta fuera de la subimagen y cuando se establece una bandera para indicar que la subimagen se trata como una imagen. El filtro de interpolación se aplica a los resultados de la función de recorte para obtener un valor de muestra predicha. El bloque se decodifica con base en el valor de muestra predicha. El bloque se reenvía para visualización como parte de una secuencia de video decodificada.
