An A/V content comprising a primary A/V content and a secondary A/V content to be inserted in the primary A/V content is delivered to a client device using adaptive streaming. A transcoding proxy enables transcoding segments of the secondary A/V content, when the segments of the secondary A/V content have different duration than a typical duration of the segments of the primary A/V content. The transcoding rewrites (S204) an original secondary A/V content manifest by indicating (S204-2), in a part thereof intended to be reused by the client device to request segments of the secondary A/V content, that transcoding is requested, by indicating the typical duration of the segments of the primary A/V content, and by modifying (S204-1) a description of said at least one representation of the secondary A/V content, both to match a rewritten timeline aligned on the typical duration of the segments of the primary A/V content.

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.

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.

This document describes an adaptive bitrate streaming method allowing streaming an audio video (AV) content to a client device using a multi content delivery network (CDN) approach. Each CDN stores multiple versions of a content that can be requested in the form of a succession of consecutive files using HTTP requests. The method is based on a use of an intermediate module, called diversity module, between an AV player of the client device and each CDN of a plurality of CDN. For each file of a version of a content requested by the AV player, the diversity module requests a manifest file to each CDN and estimates a bitrate of each CDN using reception performances of the manifest files. Each file is requested by the diversity module in the form of a succession of groups of segments structured according to a pattern comprising a predetermined number of segments. Each group comprises one set of segments for each CDN, each set comprising a number of segments intended to be requested to the CDN to which they correspond proportional to the bitrate of this CDN.
