Abstract: Embodiments of the invention relate to a server, method and computer program product for adaptive streaming to a client. The media content is encoded as at least two streams having a different quality level, each stream comprising consecutive segments. The server comprises:—a receiver configured to receive a request from the client for a selected segment of a first stream of the at least two streams; and—a transmitter configured to, in response to the request for the selected segment of the first stream:—send the selected segment of the first stream to the client; and—push a corresponding segment of a second stream of the at least two streams to the client, wherein the second stream has a lower quality level than the first stream.

Abstract: Embodiments of the invention relate to a server for streaming media content to a client and a corresponding method and computer program product. The media content is encoded as at least one stream, wherein the stream is divided into consecutive segments. The server comprises: a receiver configured to receive a request from the client for a manifest file comprising metadata of the at least one stream; and a transmitter configured to, in response to the request for the manifest file: send the requested manifest file to the client; and push a selected segment of the consecutive segments of at the least one stream to the client.

Abstract: In adaptive streaming, video segments are available in one or more quality levels, and each video segment is delivered to the client (103) in a quality level specified in a request received from that client (103). In order to reduce the risk for buffer underrun, an adaptive streaming aware network node (101) comprises: —session monitoring means (111) for collecting buffer fill information indicative for a buffer volume at the client (101) occupied by a video session; —priority calculation means (112) for determining a priority level for video segments of the session in function of the buffer fill information; and —video segment marking means (113) for marking video segments of the session with the priority level.

Abstract: A method for providing a streaming service from a server to a client, comprises the steps of requesting respective consecutive segments (SIQ1, S2Q2, S3Q3) by said client from said server, each consecutive segment being requested with an associated requested quality (Q1, Q2, Q3), at respective timing instances being determined by said client based on a timing parameter (PipelineEmptyEstimate), determined by said client, of the channel occupancy between said client and said server, such that a next request for a next segment can be transmitted by said client to said server, before complete receipt of the previous segment by said client. A client adapted to perform this method is disclosed as well.

Abstract: The invention concerns a cache manager (100) for managing the intermediate caching of segmented multimedia items. Multiple versions are available of each multimedia item, each version representing the multimedia item with a different quality. The cache manager (100) comprises control means (101, 102) to control the pre-fetching and eviction of segments. The control means (101, 102) are at least responsive to temporal and quality related inter-segment relationships (131).

Abstract: The invention relates to a method of streaming video content from a server to a client over a channel via a network. Video content is offered as a set of consecutive fragments, each fragment of said set of consecutive fragments being offered in a plurality of quality levels corresponding to respective encoded data rates. The method comprises a session of transmitting one or more of requests for fragments and receiving via the network one or more replies to the requests containing fragments with target quality levels at said client. These fragments are displayed at said client. At a capture node requests and/or replies to the requests of the session are captured. The captured data is used to reconstruct at least part of the session as experienced (QoE) at the client.
