EFFICIENT AND SCALABLE CACHING AND REPRESENTATION OF MEDIA WITH CROSS-SIMILARITIES

摘要

A system for making available at an end-user a media file, from a media provider comprising a media file patch related to at least one object, the system comprising: an encoding module at the media provider configured for determining at least one representation which resembles the media file patch, by comparing the media file patch with representations of said at least one object, and for including at least one identification corresponding with said representation in a skeleton file; a storage medium storing a dictionary including the representations of the at least one object at of the end-user and an intermediate node between the media provider and/or the end-user; a decoding module configured for decoding the skeleton file using the identification for looking up the corresponding representation in the dictionary of the storage medium and for rendering the media file patch based on the looked-up corresponding representation.

1. A system for making a media file from a media provider available at an end-user connected to the media provider through a communication network, said media file comprising a media file patch related to at least one object, the system comprising:
an encoding module at the media provider configured for:
determining at least one representation which resembles the media file patch, by comparing the media file patch with representations of said at least one object, each representation having an identification; and forincluding at least one identification corresponding with said at least one representation in a skeleton file; a storage medium storing a dictionary including the representations of the at least one object at at least one of the end-user and an intermediate node between the media provider and the end-user; a decoding module configured for:
decoding the skeleton file using the at least one identification for looking up the at least one corresponding representation in the dictionary of the storage medium; and forrendering the media file patch based on the looked-up at least one corresponding representation;said decoding module being located at at least one of the end-user and an intermediate node between the media provider and the end-user.
