Method and device for accessing multi-resolution images in a peer-to-peer communication network

摘要

The access method comprises the following steps: selecting a first data item in a digital document designated by a predetermined identifier, said digital document comprising at least first and second data items linked to each other in a chosen hierarchical relationship; verifying the presence of at least one address of a location containing said second data item of the digital document in storage means (160) of the client device; in the absence of said address in said storage means, seeking said address in the network; in the event of a positive search, storing said address in the storage means (160) of the client device; and subsequently accessing said second data item of the document from the address thus stored by anticipation and thus immediately available locally. This method allows to reduce latency when searching in a peer-to-peer network for images with the hierarchical multi-resolution JPEG 2000-format.
