A content delivery system for delivering an audio and/or video content to a mobile terminal is deployed on top of a mobile network and includes plural edge cache servers arranged using a star or hierarchical topology. The edge cache servers are connected to respective aggregation nodes of the mobile network such that a configurable breakout function of the nodes enables routing thereto packets addressed to an anycast addressing associated with the servers. When receiving a request, from the mobile terminal, for obtaining a manifest file of the audio and/or video content, an edge cache controller of the content delivery system creates a session identifier including a unicast addressing part pointing to the controller, and redirects the mobile terminal to the anycast addressing of the servers. The servers then obtain the session identifier from the mobile terminal and use the unicast addressing contained therein to receive context information from the controller.

Method for delivering an audio and/or video content in a mobile network infrastructure

A method for delivering an audio and/or video content using adaptive streaming to a terminal, the audio and/or video content being segmented into data segments available in various representations with respective audio and/or video qualities, the representations being time-aligned per segment, the segments being further divided into chunks, a controller selects, from a set of candidate caching platforms, the caching platform to be used to deliver the audio and/or video content to the terminal, as a function of a minimum burst transfer duration compared with the chunk duration as defined by an origin server providing the audio and/or video content. The controller redirects the terminal to the selected platform for further delivery of the audio and/or video content in the form bursts of chunks in response to requests for segments.

Method and controller for audio and/or video content delivery

For delivering an audio and/or video content using adaptive streaming from a cache server to a client device, the audio and/or video content being segmented into data segments available in various representations with respective audio and/or video qualities, the representations being time-aligned per segment, the segments being further divided into chunks, a method includes: obtaining a round-trip time value applicable between the cache server and the client device; computing a minimum bulk transfer size from the maximum average bitrate of the various representations of the audio and/or video content and from the obtained round-trip time value; computing a minimum bulk duration, with respect to the audio and/or video content, for the representation to be delivered to the client device; and delivering the audio and/or video content by burst transfers in the form of bulks of aggregated successive chunks for each segment in accordance with the computed minimum bulk duration.

Method and server for audio and/or video content delivery

A mechanism allowing a client application at a client device to operate multiple connection paths with a transfer protocol by implementing a master connection at an application layer and slave connections at a network layer, wherein requests for resources associated with the master connection are distributed over the slave connections established on distinct network interfaces of the client device.

A device is intended to process three-dimensional content for a server. The three-dimensional content comprises at least two image sequences obtained from different angles, wherein a three-dimensional rendering is associated to a level of disparity between said at least two image sequences. This processing device is configured to generate from a content at least two different content versions corresponding to different levels of disparity adapted to different transmission bit rates, wherein the disparity level decreases with said transmission bit rate. A server comprising the processing device, a three-dimensional content-obtaining device, and a content receiver comprising three-dimensional content-obtaining device are further disclosed.

A radio frequency identification (RFID) reader identifies in which room among several rooms the RFID reader is more likely to be located. The RFID reader includes a transmitter for transmitting an interrogating radio frequency (RF) signal. It includes a receiver for receiving RF signals generated in corresponding pairs of RFID tags. The RFID tag pairs are attached to corresponding regions of each of the rooms. Each of said RFID tag pair including a first RFID tag and a second RFID tag that are spaced from each other by a distance that is larger or equal to &#x3bb;/4 and smaller than or equal to &#x3bb;/2 with respect to a frequency of a responding RF signal originated in the pair of RFID tags. A processor selects a larger RSSI of the RSSI's of the signal pair. The processor determines a corresponding sum of the RSSI's selected from each signal pair associated with each room. The processor evaluates in accordance with determined sums, the location in which said RFID reader is more likely to be located.
