Abstract

Se divulgan métodos y aparatos para codificación de video; de acuerdo con este método, una corriente de bits correspondiente a datos codificados de la secuencia de video es generada en un lado del codificador o es recibida en un lado del decodificador, donde la corriente de bits comprende una primera sintaxis relacionada con precisión AMVR, y en donde la sintaxis relacionada con la precisión AMVR es codificada por bins de codificación de contexto con al menos dos contextos; uno o más vectores de movimiento para el bloque objetivo son codificados, en el lado del codificador, o decodificados, en el lado del decodificador, utilizando información que comprende la precisión AMVR.
