Abstract

Técnicas de codificacion y decodificacion adaptativas de video para la conversion de velocidad ascendente de cuadros, asistida por codificador (EA-FRUC). Un codificador codifica selectivamente, por lo menos, una porcion de un cuadro de video, tal como un bloque, mediante la utilizacion de un cuadro de FRUC interpolado, a modo de referencia. El codificador interpola por lo menos, una porcion del cuadro de FRUC en la misma instancia de tiempo que el cuadro de video a ser codificado todavía, y selecciona uno de entre una pluralidad de modos de codificacion de FRUC, por ejemplo, sobre la base de una decision de optimizacion de distorsion de la velocidad (RD). El codificador codifica el cuadro, mediante la utilizacion del modo de codificacion de FRUC seleccionado, el cuadro de referencia de FRUC, y cualesquiera cuadros de referencia adicionales que puedan estar indicados. Un decodificador interpola el cuadro de FRUC y lo utiliza para decodificar el cuadro codificado, con conocimiento del modo de FRUC particular que fue utilizado por el codificador. El codificador comunica el modo de FRUC por medio de uno o más parámetros existentes en el cuadro de video codificado.
