Abstract
Se proporcionan métodos para codificar y decodificar video inmersivo. En un método de codificación, los datos de video fuente que comprenden una pluralidad de vistas fuente se codifican en una secuencia de bits de video. Al menos una de las vistas fuente se submuestrea antes de codificar. Una secuencia de bits de metadatos asociada con la transmisión de video comprende metadatos que describen una configuración del submuestreo, para ayudar a un decodificador a decodificar la secuencia 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 una secuencia de bits de video inmersivo.
