20080205640 | Digital content delivery system and method - A system and a method for flexible, yet secure distribution of digital content items, optionally with an automatic payment mechanism for purchasing such content. The present invention supports the distribution of content to end user devices from a central distribution point, as in client-server models and variations thereof, and/or peer-to-peer distribution, for example between end user devices. In addition, the present invention also supports distribution models within either of these mechanisms for unitary distribution, to a specified end user device, or broadcast/multicast distribution, to a plurality of end user devices. In any case, in order for the distributed content to be operative, for example to be “played back” or otherwise displayed, the recipient end user device must be in communication with a network control center. The network control center then enables the recipient end user device to play back or otherwise display the received content, for example by sending a code to the recipient end user device. Optionally, the network control center may require payment to be received before enabling the content for the recipient end user device. Thus, the present invention supports flexible distribution of content according to a number of different distribution models, while still preventing unauthorized play back or other display throughout the lifecycle of the digital content item, and optionally enabling assured payments. | 08-28-2008 |
20090271516 | UNICAST/MULTICAST ARCHITECTURE - A system and method for providing content to users including a multicast sub-system providing content to multiple users and a unicast sub-system providing content to individual users. The multicast sub-system being operative to push to each of a plurality of user communities, content relating to the community and the unicast sub-system being operative to provide on demand to a user, content which has not been previously pushed to the user. | 10-29-2009 |

The multicast sub-system being operative to push to each of a plurality of user communities, content relating to the community and the unicast sub-system being operative to provide on demand to a user, content which has not been previously pushed to the user. | 02-18-2010 |
20110164543 | UNICAST/MULTICAST ARCHITECTURE - A system and method for providing content to users including a multicast sub-system providing content to multiple users and a unicast sub-system providing content to individual users. The multicast sub-system being operative to push to each of a plurality of user communities, content relating to the community and the unicast sub-system being operative to provide on demand to a user, content which has not been previously pushed to the user. | 07-07-2011 |
20120102575 | DIGITAL CONTENT DELIVERY SYSTEM AND METHOD - A method and system for securing digital content for transmission to an end user device. In a preferred embodiment, the invention provides for: a control center for controlling access to the digital content by the end user device; transmitting scrambled digital content to the end user device, such that the end user device cannot play back the said scrambled digital content; contacting the control center to request a PECM (personal ECM), the PECM being specific to the end user device; transmitting the PECM to the end user device by the control center; and unscrambling the scrambled digital content by the end user device according to the PECM. | 04-26-2012 |
20120139693 | Electronic Book Security Features - A method and system for fingerprinting a content item is described, the and system method include providing the content item, the content item including a set of content item elements, the set of content item elements denoted E, such that E={E | 06-07-2012 |
20140085196 | Method and System for Secondary Content Distribution - A secondary content distribution system and method is described, the system and method including a receiver for receiving a plurality of differing versions of secondary content from an provider, each one of the differing versions of the secondary content being associated with at least one of a reading mode, and a connection mode, a processor operative to determine a reading mode of a user of a client device, a selector for selecting one of the differing versions of the secondary content for display on the client device display, the selection being a function, at least in part, of matching the determined reading mode with the reading mode associated with the one of the differing versions of the secondary content and the connection mode of the client device, and a display for displaying the selected one of the differing versions of the secondary content on the client device display. Related methods, systems, and apparatus are also described. | 03-27-2014 |
20140150046 | Distributing Audio Video Content - A method of distributing audio video content is described. The method includes: receiving configuration data for a plurality of devices; for each device in the plurality of devices, computing a set of bit rates based, at least in part, on the configuration data; encoding audio video content at each bit rate in each set of bit rates to produce a plurality of encoded audio video content streams; splitting each encoded audio video content stream in the plurality of encoded audio video content streams into chunks to produce a plurality of chunked encoded audio video content streams; for each device in the plurality of devices, creating a separate index file, each separate index file including references to at least one of the plurality of chunked encoded audio video content streams; publishing a locator for each separate index file in a catalogue; and transmitting the plurality of chunked encoded audio video content streams and each separate index file to a network. Related systems, apparatus, and methods are also described. | 05-29-2014 |
