Abstract

Durante una sesión de transmisión de video inmersivo basado en mosaicos, a solicitud de cambiar de un segmento de mosaico actual asociado con un mosaico actual a un nuevo segmento de mosaico asociado con un nuevo mosaico en un tiempo de referencia, se proporciona un codificador (300) para generar uno o más fotogramas complementarios del nuevo segmento de mosaico para permitir una decodificación, por un reproductor solicitante, del nuevo segmento de mosaico del tiempo de referencia.
