  • Publication number: 20170251033
    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.

  • Patent number: 9438653
    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.

  • Patent number: 8973077
    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.

  • Patent number: 7796591
    Abstract: In access multiplexers (1) for multiplexing Internet Protocol packets to be exchanged between network devices (2) and subscriber devices (3-5), the Internet Protocol packets are encapsulated at each side of the access multiplexers (1). By providing the access multiplexers (1) with Internet Protocol routers (6-8) for routing the Internet Protocol packets via direction dependent routes, the access multiplexers (1) have become transparent for routing protocols at Internet Protocol level which use multicast Internet Protocol destination addresses or broadcast Internet Protocol destination addresses. Between the network devices (2) and the access multiplexers (1) Ethernet packets are exchanged via virtual local area network connections (21-23) and between the subscriber devices (3-5) and the access multiplexers (1) Asynchronous Transfer Mode packets are exchanged via permanent virtual connections (31-33).
