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.
