Embodiment Construction

[0061] It should be appreciated that the drawings and description of the present invention have been simplified to illustrate elements that are relevant to a clear understanding of the present invention, while many other elements found in typical digital multimedia content delivery methods and systems have been eliminated for clarity purposes.

[0062] According to a particular embodiment, the invention is described with respect to the HTTP Adaptive Streaming Protocol (or HAS), and in particular with respect to MPEG-DASH. Of course, the present invention is not limited to this particular environment, and other adaptive streaming protocols can of course also be considered and implemented.

[0063] Such as figure 1 As shown, the client-server network architecture supported by one or more networks N (only one shown in the drawings) can implement the present invention includes a plurality of client terminals CT, one or more HTTP servers SE, a plurality of Smart cache DANE, and on...

Abstract

Cache (DANE) arranged between client terminals and at least one server, said cache (DANE) being configured to receive, from client terminals, requests for at least a first representation of a segment of a multimedia content available at several representations, comprising: - a communication module (10) configured to receiving, in a first period of time, a plurality of requests for a given segment from the client terminals, each request specifying one first representation and at least one alternative representation of said given segment; - a module of relevancy (15) configured to determining at least one main relevant requested representation amongst the representations of the requests received during the first period of time; and wherein the communication module (10) is further configured to request said main relevant representation from a remote server.

Description

technical field [0001] The present invention relates generally to the technical field of adaptive streaming via, for example but not exclusively, HTTP (Hypertext Transfer Protocol), and in particular to the operation of caches arranged along a transmission path between a client terminal and a remote server. Background technique [0002] This section is intended to introduce the reader to various aspects of related art, which may be related to various aspects of the present invention that are described and / or claimed below. It is believed that this discussion helps to provide the reader with background information to facilitate a better understanding of the various aspects of the present invention. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art. [0003] Adaptive Streaming over HTTP (also known as Multiple Bitrate Switching or HAS) is rapidly becoming the dominant technology for multimedia content d...
