Embodiments relate to a method for transmission of content, executed by a content transmission device. The method includes receiving, from a client device, a content request specifying a requested content and at least one content reception deadline in an application layer part, encapsulating the requested content in a plurality of successive TCP segments; and sending the successive TCP segments to the client device by applying a congestion avoidance mechanism using a congestion window. The congestion window is determined by determining a minimum bitrate required for transmitting the requested content to the client device by the content reception deadline, determining a round-trip time between the content transmission device and the client device, and setting the congestion window equal to or greater than the product of the minimum bitrate and the round-trip time.

Method and device for transmission of content

According to an embodiment a packet forwarding device is disclosed for forwarding data packets on a link within a communication network. The packet forwarding device is further configured to perform the following steps: measuring a load of the link; detecting if the load exceeds one of a plurality of threshold indicative for a level of congestion on the link; and sending a signal to another device in the communication network signalling the level of congestion.

Congestion control within a communication network

Disclosed are an apparatus and method configured to perform media file encryption. One example method may include retrieving a media file stored in a memory during a play time operation, executing the media file and receiving additional portions of the media file during the play time operation. The method may also include processing the media file and the additional portions of the media file to generate an output media and displaying the output media on a display of a user device.

Enabling delivery of protected content using unprotected delivery services

A method for receiving an HTTP adaptive streaming video from a server, said method comprising at a client, operatively connected to said server upon receiving a chunk of said video, determining a current rate of transmission for transmissions from said server to said client; obtaining statistical information pertaining to an expected future rate of transmission, in function of at least said current rate of transmission; deriving a target rate of transmission from said statistical information; and requesting a subsequent chunk of said video in accordance with said target rate of transmission.

Method and client apparatus for receiving an http adaptive streaming video

Network devices () receiving first packets from first devices () and in response transmitting second packets to second devices (), and receiving third packets from the second devices () and in response transmitting fourth packets to the first devices (), get manipulation means () for manipulating information at layers higher than internet protocol layers of headers of packets for improving transport efficiencies between the first and second devices (). The higher layer may comprise a transport control protocol layer-4 to allow the network devices () to take over acknowledging functions of the second devices () and to take over re-transmission functions of the first devices () and to support the second devices () through offering additional buffer space and to support the first devices () through offering extended/advanced stream management.

Network device

A method for control of congestion of traffic, being categorized according to a number of layers (L), in a network node, comprises a step of monitoring the amount (n(t)) of incoming flows to this node such that, based upon this amount (n(t)) of incoming flows and on a current number of accepted layers (l(t)), a next number of accepted layers (l(t+1)) for entry into said node is determined by consultation of an action table (T). In an enhanced embodiment the action table is adjusted based on the observed traffic during an observation period.

Method and apparatus for congestion control

The present invention relates to a new error control paradigm in a packet switched network that is particularly advantageous for multicast transmission. A transmission Status Vector TSV (T) is updated at the sender side whenever a new outgoing data packet (Dj&#x2212;1) is scheduled for transmission. A corresponding Reception status Vector RSV (R) is similarly updated at the receive side whenever a new incoming and correctly indexed data packet (Dj&#x2212;1) is validly received. As soon as a missing or corrupted data packet (Dj) is detected, the update of the RSV is suspended. A request is then sent to the sender to get the current Tsv's value, or a part thereof. The erroneous data packet is then recovered from the current TSV's value (Sk,m), from the lastly updated RSV's value (Sj&#x2212;1), and from otherwise validly received data packets (Dj+1, . . . , Dk). The present invention more specifically relates to a transmitting unit () and a receiving unit () implementing that paradigm, and correspondingly to a method for protecting a flow of indexed data packets against data lost or data corruption, and a method for recovering a missing or corrupted data packet within a flow of indexed data packets.

Error control on-demand

The network unit includes a signaling unit and a video transmitting unit. The signaling unit is configured to receive a request from a decoding device requesting transmission of the video channel. The video transmitting unit is configured to transmit the video channel towards the decoding device, initially as a dedicated multimedia stream dedicatedly supplied to the decoding device and including an anchor frame as a first transmitted video frame, and further in time as a common multimedia stream commonly supplied to a plurality of decoding devices. The video transmitting unit is further configured to transmit the video channel within the dedicated multimedia stream having an earlier time frame with respect to transmission of the video channel within the common multimedia stream, and the video channel is to be initially played at an averagely slower motion speed than the nominal motion speed that the common multimedia stream is to be played.
