Patent number: 8233446Abstract: A system and method for ensuring an improved transition at the application layer when distribution of media is changed from broadcast/multicast bearers to unicast bearers and vice versa. A mapping is defined between the timeline of a Packet-Switched Streaming Service (PSS) session and the Multimedia Broadcast Multicast Service (MBMS) session timeline. This mapping is used to enable the correct positioning of the stream in a PSS session by a PSS server after a handover has occurred. Broadcast multicast service center (BM-SC) signals can support various options for media playback after a MBMS-PSS handover in a PSS session description protocol (SDP) file or in the MBMS user service description (USD). In response, the client can signal its choice in the RTSP request that is sent when switching to the PSS session.Type: GrantFiled: January 30, 2009Date of Patent: July 31, 2012Assignee: Nokia CorporationInventors: Ramakrishna Vedantham, Imed Bouazizi

Patent number: 8015296Abstract: An improved system and method for implementing Multimedia Broadcast/Multicast Service (MBMS) handover during download delivery. Various embodiments of the present invention involve the use of the HTTP/1.1 “chunked” mode to deliver updates of the file delivery table (FDT) of a session in a push-like mode. In order to allow for push delivery of the contents of a FLUTE session, each FDT instance is encoded as one part of a multipart MIME message and is sent as a separate chunk. The receiver can interpret each of the separate chunks to extract the FDT instance from the chunks. The content type of each part of the message is set to “text/xml” or another MIMI type in order to indicate that the content is an FDT instance. After parsing the FDT instance and updating the FDT, the receiver is able to identify which files of the session are of interest and can perform a HTTP GET request to retrieve a specific file.Type: GrantFiled: January 8, 2008Date of Patent: September 6, 2011Assignee: Nokia CorporationInventors: Imed Bouazizi, Ramakrishna Vedantham

Patent number: 7917644Abstract: An extension to the ISO Base Media File Format to support ALC as a broadcast protocol. The present invention also provides for the extension of the ESG to include metadata specific to the transport of SVG over mobile broadcast/multicast networks. A “BMFDP hint track” is introduced in the container file format, with the required file metadata being in these hint tracks. The present invention can be used in applications such as the preview of long cartoon animations, interactive Mobile TV services, live enterprise data feeds, live chat services, and karaoke programs.Type: GrantFiled: January 11, 2007Date of Patent: March 29, 2011Assignee: Nokia CorporationInventors: Ramakrishna Vedantham, Vidya Setlur

Patent number: 7853856Abstract: The invention relates to the generation of error correction data for available data packets and to the reconstruction of missing data packets based on available data packets and available error correction data. In order to enable an efficient error correction, the data packets are distributed at an encoding end to at least one block of data symbols, each data symbol being of equal size. Then all data symbols of a respective block are used in an encoding operation for forming a respective one of at least one error correction symbol for this block. At a decoding end, received data packets are distributed again to a block of data symbols and missing data packets are reconstructed based on these data symbols and on error correction symbols associated to the block.Type: GrantFiled: October 6, 2005Date of Patent: December 14, 2010Inventors: Ramakrishna Vedantham, David Leon, Igor Curcio

Patent number: 7746882Abstract: In a RTP stream having a plurality of FEC frames containing source blocks of media packets, random access points are inserted in front of the source blocks so as to allow a media decoder to decode the media packets as soon as FEC decoding is finished. In particular, the media packets contain forward error correction (FEC) source blocks for a multimedia broadcast/multicast-based streaming service content. As the multimedia broadcast/multicast streaming service includes dynamic interactive multimedia scene content where the source RTP packets of different media along with the FEC RTP packets are transmitted as separate RTP streams, the inclusion of the random access point facilitates immediate rendering of the dynamic interactive multimedia scene content after FEC decoding, thus reducing the tune-in latency.Type: GrantFiled: August 22, 2006Date of Patent: June 29, 2010Assignee: Nokia CorporationInventors: Ramakrishna Vedantham, Vidya Setlur, Suresh Chitturi

Patent number: 7631085Abstract: Methods, systems, transmitters, receivers, network elements and software applications in a system for acknowledging the reception of sets of data objects, wherein one or more transmitters transmit one or more sets of data objects within respective point-to-multipoint transmission sessions to a plurality of receivers, and wherein repair requests and/or delivery verification reports are transmitted by at least one of said receivers to network elements within point-to-point transmission sessions. Different back-off times are assigned for delivery verification reports and repair requests, at least two delivery verification reports of one receiver are jointly transmitted within one point-to-point transmission session, and a delivery verification report is transmitted after a completed repair session within the same point-to-point transmission session used by the repair session. Furthermore, a minimum set of parameters to be sent in delivery verification reports is shown.Type: GrantFiled: August 30, 2004Date of Patent: December 8, 2009Assignee: Nokia CorporationInventors: Ramakrishna Vedantham, David Leon, Igor Curcio

Patent number: 7594154Abstract: To support a forward error correction scheme, in which a code of the forward error correction scheme is employed at a transmitting end for encoding data for a transmission to a receiving end, the transmitting end compresses at least one binary parity check matrix associated to the employed code of the forward error correction scheme. The transmitting end then provides the compressed binary parity check matrix for a transmission to the receiving end. The receiving end receives the compressed binary parity check matrix and decompresses it for use in a forward error correction based on encoded data received from the transmitting end.Type: GrantFiled: November 17, 2004Date of Patent: September 22, 2009Inventors: Ramakrishna Vedantham, David Leon, Igor Curcio
