Abstract: A transmission of a digital content to a user terminal is managed by a network comprising a service subnetwork adapted for providing the terminal with a service token, and a digital contents distribution subnetwork which includes a control part and a transmission part. The control part of the distribution subnetwork receives a request from the user terminal for a digital content, indicating a service token. Next, if the service token is recognized as valid, an address relating to the distribution subnetwork is determined and a session token associated with said address is generated. A message indicating said address and the session token associated with said address is then transmitted to the user terminal.

Abstract: The invention relates to transform coding/decoding of a digital audio signal represented by a succession of frames, using windows of different lengths. For the coding within the meaning of the invention, it is sought to detect (51) a particular event, such as an attack, in a current frame (Ti); and, at least if said particular event is detected at the start of the current frame (53), a short window (54) is directly applied in order to code (56) the current frame (Ti) without applying a transition window. Thus, the coding has a reduced delay in relation to the prior art. In addition, an ad hoc processing is applied during decoding in order to compensate for the direct passage from a long window to a short window during coding.
