Abstract: Client configured for retrieving a video data representation of an immersive video scene streamed by a server using a streaming protocol, wherein the server is configured for providing a plurality of streams to the client, wherein each of the streams comprises a portion of the immersive video scene, the client comprising: a sending interface; a reception interface; a viewing direction receiving unit; and a stream selecting unit; wherein the sending interface is configured for transmitting a streaming request for streaming the one or more selected streams as the video data representation of the immersive video scene, wherein the sending interface receives from the stream selecting unit a selected stream information identifying the one or more selected streams, wherein the selected stream information is created by the stream selecting unit based on the viewing direction of the user of the client and based on the manifest.

Abstract: A client configured to retrieve a live-stream media content is shown. The client is configured to receive from a live-streaming server a media presentation description (MPD) describing live-stream media content composed of a sequence of segments and an information on a current segment of the sequence of segments. The client is further configured to commence retrieving the live-stream media content from the live-streaming server from a predetermined segment of the sequence of segments onwards, which the client determined based on the information.

Abstract: Media streaming is more efficient in terms of transmission bitrate consumption, transmission latency and/or fair trade of transmission capacity among several by pushing media content rather than the client pulling media content from the server. Pushing media content to the client at a varying bitrate enables to shift, at least partially, the control over the streaming from the client towards the server. The server may continue to push segments of the media content to the client even without receiving explicit queries or directives for these segments thereby reducing upstream bandwidth consumption. As far as the bitrate adaption is concerned, the server may act as a slave remotely controlled by the client in that media content is pushed at a bitrate depending on the client's most recently sent information such as reception situation information explicitly indicating the bitrate to be used.
