| 20090141664 | Device and method for synchronizing radio access logic entities of a wireless communication network - A device is dedicated to synchronizing radio access logic entities each having a local clock and forming part of a wireless communication network capable of broadcasting and/or multicasting content-defining data packets between a broadcast and/or multicast source and mobile communication terminals, via logic entities. This device includes a calculation unit tasked with i) estimating, for each logic entity of a synchronization area of the network, the time, with respect to a reference clock when said entity received a selected packet from the broadcast and/or multicast source, then ii) determining, for each logic entity, a value that represents the time difference between its reception time and the latest reception time among those of the logic entities, and iii) ordering each logic entity to wait for a period of time equal to the value which was determined for it before retransmitting each packet received from the broadcast and/or multicast source to the terminals located within its synchronization area. | 06-04-2009 |
| 20110038297 | TRANSMISSION OF MULTICAST AND BROADCAST CONTENT AND METHOD THEREOF - The present invention provides a method of transmitting multicast and broadcast content in a mobile access network, the mobile access network comprising: at least one multicast-broadcast service zone with at least one Base Station, a Multicast-Broadcast server for each one of the multicast-broadcast service zones, the mobile access network coupled to a content distribution network, the content distribution network comprising a content server coupled to an JP multicast network, the content server being adapted for multicast and broadcast transmission, the method comprising the steps of: sending a first join request using a membership protocol for a multicast group from a Multicast-Broadcast server to the content distribution network; sending a second join request using the membership protocol and sending a first multicast IP packet from the multicast/broadcast content server to the multicast-broadcast server using a first multicast routing protocol. The method further comprises: encapsulating the first multicast IP packet into a second multicast IP packet; sending the second multicast IP packet to the local multicast group of the multicast-broadcast service zone using a second multicast routing protocol. | 02-17-2011 |

| 20100082644 | IMPLICIT INFORMATION ON MEDIA FROM USER ACTIONS - The exemplary embodiments relate to a new interactive method and system to implicitly enrich any multimedia content effortlessly by combining multiple pieces of information on media content. The new solution consists of logging implicit user actions (e.g., display, modify, remove, copy, classify, send) on media from their terminals (e.g., PC, mobile phone, PDA). Pertinent information related to media will be then statistically generated and consolidated from these logged media actions and will be used to enrich related media content. A unique identifier number will be associated with each media in order to retrieve its associated information. | 04-01-2010 |
