Abstract: Method for managing a streaming processing of a multimedia video spatially tiled stored on a network equipment, and corresponding terminal. A terminal for managing a streaming processing of a multimedia video (10) spatially tiled (400) with a set of tiles and stored on a network equipment (300), a tile (400) covering a portion of a scene of the multimedia video, said multimedia video being temporally divided into a plurality of video segments (Segment 1, …, Segment n), a video segment being further defined by a plurality of tile segments, each tile segment being associated with a tile (400) of the set of tiles, which comprises one or more memories and one or more processors configured to: -process (701) one or more tile segments of a current video segment (Segment1, …, Segment n) for delivering one or more first portions of the scene of the multimedia video comprising a part of the scene to be displayed through a current viewport (VP); -upon receipt (702) of a command during the processing of the current video segment, retrieve (703) a halt image of the multimedia video associated with a given moment of the current video segment (Segment 1, …, Segment n), said halt image being defined by one or more second portions comprising said one or more first portions.

Abstract: During the delivery of a sequence of packets from a server to a client device, when an expiration time associated with an initial payload of a data packet belonging to a sliding window for delivery is reached without reception of a corresponding acknowledgment from the device, the server (300) resends the data packet with a new payload corresponding to the initial payload of a next data packet to be transmitted through the sliding window.

Abstract: A method of controlling energy consumed by a multimedia streaming application executed in a multimedia streaming system, the method comprising: receiving (358), at an end-user device, a message including information representative of energy consumed by at least one node of the multimedia streaming system when applying at least one process on content having a first profile delivered by the multimedia streaming application prior to delivering the content having the first profile to the end-user device; and requesting (359), at the end-user device, content having a second profile based on the received information representative of the energy consumed by the at least one node.

Abstract: According to embodiments, an enhancement layer segment may be requested in addition to a base layer segment for a same video. The enhancement layer may be requested, in a low priority, so that the base layer may be delivered in priority. If the enhancement layer can be obtained by a deadline, a subsequent base layer segment may be requested at a higher quality (e.g., at a bitrate lower than or equal to the sum of the bitrates of the previously requested base layer and enhancement layer segments). If, for example, at a playback time, the enhancement layer segment is not obtained, it may be determined that the quality cannot be increased and subsequent requests for enhancement layer segments may be cancelled (e.g., not transmitted). According to embodiments, probing may repeat (e.g., any of immediately, regularly, periodically, …) to detect available bandwidth variations.

Abstract: A client (100) is able to manage a multimedia content in such a way that the buffering can be reduced as much as desired down to zero by selecting a representation for a next segment to be requested for which the first frame can be received at least in the frame duration.
