  • System and method for pre-encryption of transmitted content
    Patent number: 7333610
    Abstract: A system and a method for the creation and transmission of “pre-encrypted” digital content, which is encrypted before being placed on a distributed media transmission server. Preferably a plurality of such servers are used, for example in order to be able to place such a media transmission server in physical proximity to the end user client, whether in terms of geographical proximity or proximity through the network. Use of a plurality of transmission servers also optionally enables the media content to be transmitted flexibly, according to the request of the end user through the end user client.
