Abstract

Se describen conceptos para codificar y decodificar los datos de vistas múltiples para video inmersivo. En un método de codificación, se generan metadatos que comprenden un campo que indica si una unidad de datos de parche de los datos de vistas múltiples comprende datos restaurados para representar datos faltantes. Los metadatos generados proporcionan un medio para distinguir unidades de datos de parche que comprenden datos de textura y profundidad originales de las unidades de datos de parche que comprenden datos restaurados (p. ej., datos de textura y de profundidad restaurados). El suministro de tal información dentro de los metadatos del video inmersivo puede abordar problemas asociados con el mezclado y la reconstrucción de vistas reducidas. También se proporciona un codificador y un decodificador para datos de vistas múltiples para video inmersivo, y una secuencia de bits correspondiente, que comprenden metadatos.
