AUDIO DECODER

Embodiments according to the invention are related to an audio decoder, for providing a decoded audio representation on the basis of an encoded audio representation, wherein the audio decoder is configured to spatially render one or more audio signals; wherein the audio decoder is configured to receive a plurality of packets of different packet types, the packets comprising one or more scene configuration packets providing a renderer configuration information defining a usage of scene objects and/or a usage of scene characteristics, the packets comprising one or more scene update packets defining a update of scene metadata for the rendering, the packets comprising one or more scene pay toad packets comprising definitions of one or more of the scene objects and/or definitions of one or more of the scene characteristics; wherein the audio decoder is configured to select definitions of one or more scene objects and/or definitions of one or more scene characteristics, which are in included in the scene payload packets, for the rendering in dependence on the renderer configuration information; and wherein the audio decoder is configured to update one or more scene metadata in dependence on a content of the one or more scene update packets. Further embodiments are related to encoders, methods and bitstreams. Further embodiments are related to decoders, encoders, methods and bitstreams with scene update packets with update conditions, with scene configuration packets providing a renderer configuration information defining a temporal evolution of a rendering scenario and with a timestamp information and/or with subscene cell information, wherein the cell information defines an association between the one or more cells and respective one or more data structures. Modalidades de acuerdo con la invención se refieren a un decodificador de audio, para proporcionar una representación de audio decodificada con base en una representación de audio codificada, en donde el decodificador de audio se configura para renderizar espacialmente una o más señales de audio; en donde el decodificador de audio se configura para recibir una pluralidad de paquetes de diferentes tipos de paquetes, los paquetes que comprenden uno o más paquetes de configuración de escena que proporcionan una información de configuración de renderizador que define un uso de objetos de escena y/o un uso de características de escena, los paquetes que comprenden uno o más paquetes de actualización de escena que
