| 20080228912 | Enhanced Quality Reporting for Transmission Sessions - This invention relates to methods, computer program products, clients, servers, systems and protocols in the context of reporting a quality of a transmission session according to one or more metrics, inter alia to adapt quality reporting to a switching of content within the transmission session and to allow faster session startup. | 09-18-2008 |
| 20090307564 | Point-to-point repair request mechanism for point-to-multipoint transmission systems - This invention relates to a method, system, transmitter, network element, receiver and software application for a system capable of point-to-multipoint transmission, where one or more data packets are transmitted from a transmitter to one or more receivers, where at least at one specific receiver of said receivers, a reception of repair data packets is required, where repair information is signaled to a repair server in order to trigger a transmission of the repair data packets, and where the repair information comprises information related to the number of transmitted data packets correctly received at the specific receiver. The system may for instance be the 3GPP Multimedia Broadcast Multicast System, the transmission of data packets may for instance be controlled by the File Delivery Over Unidirectional Transport protocol and the signaling of the repair information may for instance be controlled by the Hypertext Transfer Protocol. | 12-10-2009 |
| 20100121977 | Predictive Bit-Rate Modification of Content Delivery in a Wireless Network - A sender in a wireless network may adjust the encoding bit rate of the transmitted content and/or the transmission bit rate of the content based on the predicted future channel throughput at a predicted future geographical position of a client mobile device, such as a cellular telephone. By appropriately adjusting the bit rate prior to the client mobile device experiencing the predicted low throughput, the likelihood of continuous content consumption by the client mobile device, even while experiencing the predicted low throughput conditions, may be increased. The prediction may be performed at the network side and/or at the client mobile device side. | 05-13-2010 |
| 20100215339 | Refined quality feedback in streaming services - A method for quality feedback in a streaming service is shown, wherein at least one media stream is streamed to a client for playback, the method comprising determining a quality feedback value according to at least one quality metric from a pre-defined set of quality metrics, wherein the pre-defined set of quality metrics contains a quality metric related to at least one of the playback of the at least one media stream and a corruption of one out of at least two types of frames contained in the at least one media stream, and reporting the quality feedback value to a server. A system, a client, a server, a computer program, a computer program product and a protocol for quality feedback are also shown. | 08-26-2010 |
| 20110117934 | METHOD AND APPARATUS FOR MOBILE ASSISTED EVENT DETECTION AND AREA OF INTEREST DETERMINATION - An approach is provided for determining the existence of an event based on information collected from mobile devices. Reception is caused, at least in part, of media from a plurality of mobile devices. A plurality of event vectors for the respective mobile devices is determined. Each of the event vectors includes geo-location information and timing information of the corresponding mobile device. The existence of the event is determined based on the received media and the event vectors. | 05-19-2011 |

| 20080215704 | Transmission of Information Relating to a Quality of Service - Methods of transmitting information relating to a quality of service are shown, which information is to be transmitted in at least one direction between a first device | 09-04-2008 |
| 20090204865 | DATA REPAIR ENHANCEMENTS FOR MULTICAST/BROADCAST DATA DISTRIBUTION - A method, system, device, and computer code product is disclosed in which a sender transmits data to a plurality of receivers via a point-to-multipoint session. The receiver sends data repair requests to the sender requesting data expected but not received and the sender retransmits the expected but not received data via the point-to-multipoint session. The sender can also schedule point-to-point data repair sessions with individual receivers if the retransmission via the point-to-multipoint session does not correct all errors. The sender can be configured to delay point-to-point repair sessions using a randomization mechanism based on the number of receivers using the point-to-multipoint session. | 08-13-2009 |
| 20100029266 | SYSTEM AND METHODS FOR QUALITY OF EXPERIENCE REPORTING - In accordance with an example embodiment of the present invention, a method, comprising; verifying, by a user equipment, that one or more rules associated with a process of reporting quality of experience metrics are satisfied, said quality of experience metrics being associated with a multimedia telephony call; generating quality of experience metrics report, by the user equipment, according to configuration information related to the process of reporting quality of experience metrics if the rules associated with a process of reporting quality of experience method are satisfied; and sending the quality of experience metrics report to a server according to the configuration information, wherein the server is outside data links connecting the user equipment to at least another user equipment participating in the multimedia telephony service. | 02-04-2010 |
| 20100135290 | USAGE OF FEEDBACK INFORMATION FOR MULTIMEDIA SESSIONS - An apparatus and method configure RTCP packets in a control feedback handling in multimedia sessions. The apparatus and method are configured to provide sending of any RTCP individual packet as a non-compound RTCP packet an order within a time interval. The apparatus and method are configured so that an excessive length of compound RTCP packets are handled by fragmenting each compound RTCP packet in smaller non-compound packets and sending it spaced over time. The apparatus and method guarantee RTCP non-compound packets to provide an equivalent functionality as the RTCP compound packets by providing the same information to the receiver, and the receiver does not lack any feedback information. The apparatus and method are also configured to use semi-compound RTCP packets, where at least two non-compound/individual RTCP packets (but less than all the non-compound/individual RTCP packets that would be sent as compound packet) are sent together as a semi-compound RTCP packet. | 06-03-2010 |
| 20100153578 | Method and Apparatus for Peer to Peer Streaming - In accordance with an example embodiment of the present invention, An apparatus, comprising a processor configured to assign at least one of a plurality of real time transport protocol data units to at least one of at least two peer to peer partial real-time transport protocol streaming sessions, based at least in part on at least one timestamp associated with the at least one of the plurality of real time protocol data units. The plurality of real time transport protocol data units, is associated with the real time transport protocol media stream. | 06-17-2010 |
| 20100329126 | METHOD AND APPARATUS FOR HANDLING BROKEN PATH IN PEER-TO-PEER NETWORK - A method comprises (a) detecting a packet loss in a partial data packet stream in a peer-to-peer network; (b) signaling an indication of lost packets to one or more sending peers serving the partial data packet stream corresponding to the packet loss; (c) after expiration of a threshold period of time without receiving lost packets, signaling one or more candidate peers a request for retransmission of the lost packets, the candidate peers being peers not serving the partial data packet stream; and (d) receiving the lost packets through one of the candidate peers. | 12-30-2010 |
