摘要

Network equipment (GW) arranged along a transmission path between a client terminal and at least one server, said network equipment being configured to receive a request from the client terminal for a first representation of a segment of a multimedia content available at several representations, said request further specifying one or several alternative representations of said segment, which comprises a bandwidth estimator (14) configured to determine at least one downstream bandwidth along a transmission path between a server and the client terminal, a filtering module (16) configured to modify said request by removing each alternative representation of the request whose associated bitrate is higher than the sum of the determined downstream bandwidth and a threshold, and a communication module (11) configured to forward the modified request to an upstream network element arranged between the network equipment (GW) and the server.
