Abstract

Se describen el método y el aparato de codificación de secuencias de video VR360, en donde se incluye compensación de movimiento envolvente como herramienta de codificación. De acuerdo con el método, un flujo de bits correspondiente a los datos codificados de la secuencia de video VR360 se genera en un lado del codificador o se recibe en el lado del decodificador, donde el flujo de bits comprende una o más sintaxis de PPS relacionadas con la información de compensación de movimiento envolvente en un PPS (Conjunto de Parámetros de Imagen). La secuencia de video VR360 se codifica en el lado del codificador o se decodifica en el lado del decodificador en función de la información de compensación de movimiento envolvente.
