摘要： For delivering an AV live content, time being divided into transmission periods, the AV live content being divided into chunks, a server device performs: obtaining at least one multicast reference stream (400) intended to transport one chunk (401) per transmission period; obtaining at least one multicast side stream (410) intended to transport, for each transmission period, a plurality of chunks (411, 412,413) which at least comprises the same chunk (413) as in each multicast reference stream and at least one preceding chunk (411; 412); and synchronously transmitting each multicast reference stream and each multicast side stream along the transmission periods. A device willing to receive the AV live content performs: joining one said multicast side stream for obtaining at least one chunk transmitted in a first transmission period; and switching to one said multicast reference stream for obtaining subsequent chunks which are transmitted from a second transmission period following the first transmission period.

摘要： An audio-visual live content delivery system includes: a client (110) having access to a provider network (102) via a gateway (140); an audio-visual live content delivering equipment (120) comprising a multicaster for transmitting audio-visual live contents in multicast form via the provider network (102); a de-multicaster (150) being able to perform a conversion in unicast form of audio-visual live contents received in multicast form from the multicaster; and a controller (130) managing routing of requests to get audio-visual live contents. The client (110) performs a discovery procedure aiming at receiving information on potential presence and availability of the de- multicaster (150). When the client (110) intends receiving a targeted audio-visual live content, the client (110) sends to the controller (130) a request providing indication of presence and availability, or not, of the de-multicaster (150). Then the controller (130) decides how redirecting the client (110) to fulfill the request, according at least to the indication of presence and availability, or not, of the de-multicaster (150).

摘要： 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.

摘要： For delivering an audio and/or video content to a mobile terminal, a content delivery system is deployed on top of a mobile network. The content delivery system comprises plural edge cache servers arranged using a star topology or a hierarchical topology. The edge cache servers are connected to respective aggregation nodes of the mobile network such that a configurable breakout function of the aggregation nodes enables routing thereto packets addressed to an anycast addressing associated with the edge cache 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 edge cache controller, and redirects the mobile terminal to the anycast addressing of the edge cache servers. The edge cache servers then obtain the session identifier from the mobile terminal and use the unicast addressing contained therein to receive context information from the edge cache controller.

摘要： A local area network comprises plural content delivery network CDN receiver devices so as to enable player-equipped terminals in the local area network to receive audio and/or video contents. The disclosed method comprises: obtaining capacity information from the CDN receiver devices; selecting, according to the capacity information, at least one CDN receiver device for a session of delivering an audio and/or video content to the player; when the session ends, the selected at least one CDN receiver device holds in place, during a predefined time duration, processing resources for a potential upcoming session; when another session starts before expiry of the predefined time duration, the processing resources hold in place are used for the new session. And when another session starts after expiry of the predefined time duration, reselection of at least one CDN receiver device, according to updated capacity information, is performed.
