摘要： The method of transmitting data packets associated with an importance level comprises a step (305) of estimating available rate on the network. In case a variation is detected in estimated available rate greater than a first predetermined value, determination is made (309-317) of whether there is an increase in the round trip time on said network that is greater than a second predetermined value. If yes, the data packets are transmitted (319-325) at a rate lower than the estimated available rate.In embodiments, in case a variation is detected in estimated available rate greater than a first predetermined value and before the step of detecting an increase in the round trip time, a step (307) is carried out of transmitting packets of lower importance level than the average of said importance levels by using the current estimated available rate and the round trip time is determined on the basis of the sending of those packets.

摘要： A central server in a network of a hybrid peer to peer type, receives a request from a client for obtaining a digital document, where the request contains a reference of the digital document. The server selects a peer system of the network likely to contain the digital document, and generates an access key for controlling access to the digital document by the client, where the access key is generated by an encrypting method using a private key of the central server, a current time when the encrypting method is executed and an address of the client on the network. The server then sends a message to the client, where the message has the reference of the digital document, an address of the selected peer system on the network and the generated access key.

摘要： An encoder extracts motion vectors from a frame I(t−1) preceding the frame I(t) being encoded and processes them to create an estimated motion vector field I(t) for the frame being encoded. A minimized difference between the motion vector field of the frame being encoded and the estimated motion vector field is used to generate transform parameters, which are transmitted to the decoder as auxiliary information along with the usual motion prediction information. The decoder receives the transform parameters. The decoder also creates an estimated motion vector field I(t) for based on a preceding frame I(t−1) and applies the transform parameters to the estimated motion vector field to obtain missing motion vectors. The motion vector field rebuilt using the reconstructed missing motion vectors is used for subsequent error concealment/decoding/displaying.

摘要： The invention concerns a method of notifying control information to a congestion control mechanism in charge of controlling data segments sending rate of a server towards a client. The control information includes loss events where a loss event corresponds to one or more data segments lost. The method comprises a step of receiving data segments into a reception buffer at the client, a step of detecting loss events from the received data segments and a step of notifying the congestion control mechanism with a number of loss events that is dependent on the number of detected loss events and a measure of criticality related to the reception of the data segments by the client. The measure of criticality can be derived from the filling level of the reception buffer, the reception of data segments being in a critical state when the reception buffer is experiencing overflow or underflow conditions.
