Multimedia content delivery method and system
View Patent ↗The present invention relates to a method for the distribution of multimedia content, comprising: a first step comprising a download in “push” mode of a multimedia content, in a partial way, from a content server to a client device, and a second step comprising a download of the missing elements of said multimedia content in “pull” mode via a “peer to peer” mechanism from a second client device, and in that the multimedia content can be reconstituted with n+p blocks, n and p being non-null natural integers, n blocks being downloaded during said first step and p blocks being downloaded during the second step, the multimedia content being exploitable only after reception of n+p blocks.
1. Method for distributing multimedia content, comprising:
a first step comprising a download in “push” mode of a multimedia content, in a partial way, from a content server to a first client device, and
a second step comprising a download of the missing elements of said multimedia content in “pull” mode via a “peer to peer” mechanism from a second client device (EC 2 ),
and in that the multimedia content can be reconstituted with n+p blocks, n and p being non-null natural integers, n blocks being downloaded during said first step and p blocks being downloaded during the second step, the multimedia content being exploitable only after reception of n+p blocks.
2. Method for distributing multimedia content according to claim 1 , wherein the first and second client devices are located under the same DSLAM.
3. Method for distributing multimedia content according to claim 1 , wherein the first and second client devices are located under neighbouring DSLAMs.
4. Method for distributing multimedia content according to claim 1 , wherein at least one of the first and second client devices is a set-top box with a hard disk or a personal computer.
5. Method for distributing multimedia content according to claim 1 , wherein certain blocks are systematically loaded onto several client devices, for example blocks enabling viewing of the start of a film or films of a degraded quality, so that a user can begin viewing while waiting for the loading by a “Peer to Peer” mechanism to happen.
6. System for the distribution of multimedia content comprising at least a multimedia server, a communication network, a DSLAM and at least two client devices for the implementation of the method according to claim 1 .
7. Digital device, comprising:
means for receiving by download in “push” mode a multimedia content, in a partial way, from a content server, and
means for receiving by download, the missing elements of said multimedia content in “pull” mode via a “peer to peer” mechanism from a second client device,
and in that the multimedia content can be reconstituted with n+p blocks, n and p being non-null natural integers, n blocks being downloaded in “push” mode and p blocks being downloaded in “pull” mode, by a “peer to peer” mechanism, the multimedia content being usable only after the reception of n+p blocks.
