摘要： The invention concerns a cache manager (100) for managing the intermediate caching of segmented multimedia items. Multiple versions are available of each multimedia item, each version representing the multimedia item with a different quality. The cache manager (100) comprises control means (101, 102) to control the pre-fetching and eviction of segments. The control means (101, 102) are at least responsive to temporal and quality related inter-segment relationships (131).

摘要： Method to provide video chunks to a client entity (C) using a request-response protocol. Each video chunk is available at a server entity (S) as a plurality of encoded video chunks encoded according to respective quality levels. The method includes the steps of: —the server entity sending to the client entity information on the different quality levels, —the client entity making a selection of one quality level of the different quality levels based on criteria related to local transfer bandwidth related parameters, —the client entity requesting the server entity to transfer to it encoded chunks encoded in that one chunk quality level and —the server entity sending the encoded chunks encoded according to that one chunk quality level to said client entity, —the server entity sending to the client entity additional information related to a transfer time of the encoded chunks from the server entity to the client entity, and —the client entity in making the selection of the one quality level taking into account also the additional information.
