Abstract

Se proporcionan métodos para la codificación y decodificación de video inmersivo. En un método de codificación, los datos de video fuente que comprenden una pluralidad de vistas fuente se codifican en un flujo de bits de video. Al menos una de las vistas fuente se submuestrea antes de la codificación. Un flujo de bits de metadatos asociados con la transmisión de video comprende metadatos que describen una configuración del submuestreo, para ayudar a un decodificador a decodificar el flujo de bits de video. Se cree que el uso de vistas submuestreadas puede ayudar a reducir los artefactos de codificación, en comparación con un enfoque de codificación basado en parches. También se proporciona un codificador y un decodificador para video inmersivo, y un flujo de bits de video inmersivo.
