摘要：
The invention concerns a client terminal (CT) configured for downloading an upcoming sequence of segments of a multimedia content stored in at least one remote server, each segment being derived from one or more representations, characterized in that it comprises:
- calculator (7) configured to determine, for at least some combinations of available representations of said segments stored, or not, in identified caches arranged between the client terminal (CT) and a server:
■ a value of a utility function of the perceived quality associated with each of said combinations;
■ a time for downloading each of said combinations;
- a module (8) configured for selecting, amongst the determined utility function values, a highest utility function value with a downloading time inferior to a time threshold,
- a communication module (2) configured for downloading, at the client terminal (CT), the representations associated with the selected combination of representations.
