Abstract: Methods and systems for coordinating user terminals are disclosed. A user terminal may receive a user terminal identifier and a sensor identifier from a user terminal, determine a group topology based on the user terminal identifier and the sensor identifier to identify a spatial relationship relative to the user terminal, receive a media signal, and identify a subsection of the media signal. The user terminal also may generate subsection information to assign a subsection of the media signal to the user terminal corresponding to the spatial relationship, and may communicate the subsection information to the user terminal.

Abstract: The invention relates to a method for data repair in a system capable of one-to-many transmission. The method comprises transmitting data from a sender to at least one receiver and provides for various sender driven or receiver driven repair methods of missing data.

Abstract: Local discovery of mobile network services involves coupling a communications device to a local network segment of a mobile data network. An announcement is sent from the communication device and/or a network entity (such as a network proxy) describing a service available via the respective devices. The announcement is receivable by any device on the local network segment. A request is received at the device for a detailed description of the service information in response to the announcement.

Abstract: The specification and drawings present a new method, system, apparatus and software product for signaling parameters of multiple buffers by a terminal to a server and determining multiple buffer status of the terminal by the server using these parameters, e.g., for an adequate rate adaptation of multimedia streaming services provided to the terminal by the server. The terminal can be (but is not limited to) a computer, a communication device, a wireless communication device, a portable electronic device, a mobile electronic device, a mobile phone, etc.

Abstract: A method, system, device and software code product are disclosed which provide efficient multicast/broadcast distribution of formatted data. Formatted data can comprise metadata and content (media data) and several embodiment of the inventions disclose retransmitting the metadata in order to increase the reliability of the file distribution by increasing the chances that the metadata is received without error. In addition, embodiments of the invention disclose scheduling transmission of data packets of formatted data so that the metadata packets are transmitted at an earlier time location than they occur in the original formatted data file to decrease latency in file playback.

Abstract: 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.
