Abstract:
1. An access method for an image retrieval system in a data transmission network organized using the client/server principle, for enabling access to image data that are stored in a data archive of a file server that is spatially remote with reference to the geographical location of a client terminal accessing the image data, comprising: transmitting a search request of the client terminal to a network server in order to request a portion of an image data sequence stored in the data archive; modifying and transmitting a formatted data stream from the network server to the client terminal, the modified data stream including a header carrying only metadata relating to individual frames of an image data sequence sent via the data transmission network and an additional data field for an access key embedded in the header as additional meta information, the access key being to bulk data relating to individual frames of the image data stored in the data archive; transmitting to the file server a component of the image data that includes an access key to access at least a portion of the image data that is requested by the client terminal from a network server, wherein the access key is transmitted from the network server to the client terminal, for indirectly addressing the at least a portion of the image data, and the network server does not transmit the image data over the transmission network.
