摘要： The invention provides a solution for providing a freeze-and -view-around effect from a multi-view session comprising views for a user device adapted to receive a multi-view session. The user device is adapted to request the freeze-and -view-around effect from a server while viewing a session. The server upon reception of the request from the user device generates frames of views from the multi-view session required for generating the freeze-and-view-around effect at certain time at the user side. Further the server determines also a transmission order of the generated frames and sends the frames towards the user over a unicast connection. The user device is adapted to generate from the received frames the freeze-and-view-around effect.

摘要： The invention pertains to a Mixer and a Method for providing media streams towards a plurality of endpoints (EP1, EP2), the media streams originating from one or more media source (SRC). Within the method at least a first request set (COPR1) of a first endpoint (EP1) of said plurality of endpoints and a second request set (COPR2) of a second endpoint (EP2) of said plurality of endpoints are received, whereby a request set comprises information relating to at least a subset of one or more codec parameters, and whereby a request set pertains to a media stream, whereby said first request set and said second request set pertain to a same media content. Said received first request set (COPR1) and said received second request set (COPR2) is aggregated into an aggregated request set (COPRA) pertaining to a first media source (SRC). Thereafter one or more media streams according to said aggregated request set (COPRA) are requested from said first media source (SRC). On receiving said one or more requested media streams from said first media source (SRC), one or more media streams are delivered towards said first endpoint (EP1) according to the first request set (COPR1) and one or more media streams are delivered towards said second endpoint (EP2) according to the second request set (COPR2), whereby portions of said media streams are delivered towards said endpoints according to the respective request set.
