A system for a virtual reality, VR, augmented reality, AR, mixed reality, MR, or 360-degree video environment configured to receive video and audio streams to be reproduced in a media consumption device, wherein the system comprises: at least one media video decoder configured to decode video signals from video streams for the representation of VR, AR, MR or 360-degree video environments to a user, and at least one audio decoder configured to decode audio signals from at least one audio stream for the representation of an audio scene, wherein the system is configured to request at least one audio stream from a server on the basis of at least the user's current viewport and/or head orientation and/or movement data and/or interaction metadata and/or virtual positional data, and wherein the system is configured to request the at least one audio stream from the server on the basis of a distance of the user's position from the boundaries of neighbouring and/or adjacent video environments associated to different audio scenes, wherein a plurality of audio scenes (150A, 150B) are defined for multiple video environments such as adjacent and/or neighbouring video environments, so that first streams are provided associated to a first, current audio scene and, in case of user's transition to a second, further audio scene, both the audio streams associated to the first audio scene and the second audio streams associated to the second audio scene are provided, wherein the first streams associated to the first audio scene are obtained at a higher bitrate when the user is in the first environment associated to the first audio scene, while the second streams associated to the second audio scene associated to the second environment are obtained at a lower bitrate when the user is in the beginning of a transitional position from the first audio scene to the second audio scene, and the first streams associated to the first audio scene are obtained at a lower bitrate and the second streams associated to the second audio scene are obtained at a higher bitrate when the user is in the end of a transitional position from the first audio scene to the second audio scene, wherein the lower bitrate is lower than the higher bitrate. at least one media video decoder configured to decode video signals from video streams for the representation of VR, AR, MR or 360-degree video environments to a user, and at least one audio decoder configured to decode audio signals from at least one audio stream for the representation of an audio scene, wherein the system is configured to request at least one audio stream from a server on the basis of at least the user's current viewport and/or head orientation and/or movement data and/or interaction metadata and/or virtual positional data, and wherein the system is configured to request the at least one audio stream from the server on the basis of a distance of the user's position from the boundaries of neighbouring and/or adjacent video environments associated to different audio scenes, wherein a plurality of audio scenes (150A, 150B) are defined for multiple video environments such as adjacent and/or neighbouring video environments, so that first streams are provided associated to a first, current audio scene and, in case of user's transition to a second, further audio scene, both the audio streams associated to the first audio scene and the second audio streams associated to the second audio scene are provided, wherein the first streams associated to the first audio scene are obtained at a higher bitrate when the user is in the first environment associated to the first audio scene, while the second streams associated to the second audio scene associated to the second environment are obtained at a lower bitrate when the user is in the beginning of a transitional position from the first audio scene to the second audio scene, and the first streams associated to the first audio scene are obtained at a lower bitrate and the second streams associated to the second audio scene are obtained at a higher bitrate when the user is in the end of a transitional position from the first audio scene to the second audio scene, wherein the lower bitrate is lower than the higher bitrate.
