A method and system of virtual multicasting content is disclosed. The method and system disclosed enable the receipt of virtual multicast content without requiring the expensive investment in the infrastructure necessary for a network to be multicast enabled. The virtual multicasting may be performed according to a method of virtual multicasting multicast content on non-multicast enabled networks, comprising the steps of determining if an attached network is multicast enabled, if the attached network is not totally multicast enabled, querying for virtual multicast requests for the multicast content from non-multicast enabled client computers, listening for virtual multicast requests, and determining, based on the virtual multicast requests, which client computers request the multicast content, from the unicast addresses, and the requested methods of delivery for the multicast content. The network includes client computers that have unicast addresses and the at least one virtual multicast request includes a unicast address identifying a client computer of the network and a requested method of delivery for the multicast content.

Virtual multicasting

A system and method (the 'Channel Dancer') of delivering broadband content that has been personalized for a recipient user is disclosed. By excelling in the personalization of the user's view of broadband content on the Internet and otherwise, the system and method develop 'stickiness' with the user that maximizes the benefits and effectiveness of advertising and related activities. The system preferably comprises a network operations center (&#x201c;NOC&#x201d;) that receives and packages content, with promotional materials, on virtual channels, a transmission medium that transmits the virtual channels, a broadband ISP with a point-of-presence (&#x201c;POP&#x201d;) server that receives the virtual channels and routs virtual channels to a user machine, based on requests received from client software (the &#x201c;client&#x201d;) resident on the user machine and filtering performed by the client based on a personal profile of the user.

Method and system for delivering personalized broadband content

A personalized content manager is disclosed. The personalized content manager comprises an apparatus, system, method, and computer readable medium that includes or performs the steps of receiving input regarding the filtering of broadband content, filtering the broadband content with one or more content categories based on the filtering input, filtering the content with one or more of a plurality of content sources based on the filtering input, and generating a personalized content management interface screen that includes a list of titles of the filtered content.

Personalized content management

A method and system for digital rights management is disclosed. The method and system utilize standalone certificates linked with hardware profiles to provide and efficient mechanism for digital rights management. A method for digital rights management includes receiving content at a client computer. The content is encrypted with an encryption key. The method further includes the client computer requesting the encryption key from a digital rights management (DRM) server using a digital certificate, the server receiving the request and the DRM server determining if the digital certificate is valid. The DRM server is remote from the client computer.
