Etat de la techniqueState of the art
De nombreux appareils électroniques, souvent grand public, possèdent l'option de leur rattacher un périphérique de stockage : disque dur USB {Universal Sériai Bus) , clé flash USB, stockage réseau (NFS : Network File System) etc. Dans l'éventualité où l'utilisateur utilise cette option, l'appareil peut présenter des fonctionnalités additionnelles, qui n'étaient pas utilisables avant d'avoir rattaché le périphérique. Ces fonctions peuvent être par exemple : enregistreur numérique ou PVR (Personal Video Recorder) dans le cas d'un récepteur/décodeur (Set-Top Box), partage de fichiers stockés sur un disque dur (cas classique d'un routeur domestique), diaporama ou slide show (périphérique de type écran LCD) etc. Le logiciel qui fournit ces fonctionnalités n'est pas utilisé tant que l'utilisateur n'a pas branché de périphérique de stockage. La place qu'il occupe en mémoire non-volatile dans le produit n'est donc pas valorisée .Many electronic devices, often for the general public, have the option of attaching a storage device to them: USB hard disk (Universal Serial Bus), USB flash drive, Network File System (NFS) and so on. In the event that the user uses this option, the device may have additional features that could not be used before attaching the device. These functions can be for example: digital recorder or PVR (Personal Video Recorder) in the case of a receiver / decoder (Set-Top Box), file sharing stored on a hard disk (classic case of a home router), slide show or slide show (LCD screen device) etc. The software that provides these features is not used until the user has connected a storage device. The place it occupies in non-volatile memory in the product is therefore not valued.

L'évaluation liée à l' authentification ou non du logiciel est également représentée (étape 04) Figure 1.The evaluation related to the authentication or not of the software is also represented (step 04) Figure 1.
Si le Logiciel Supplémentaire n'est pas présent sur le Périphérique 20, s'il est altéré ou obsolète, l'Appareil 10 procède au chargement du Logiciel Supplémentaire directement dans le Périphérique 20, ou indirectement à travers l'Appareil 10. Ce chargement peut se faire éventuellement à l'aide d'une connexion réseau de type internet. Le téléchargement du Logiciel Supplémentaire sur le Périphérique est illustré (étape 05) Figure 1. Le chargement du Logiciel Supplémentaire peut être effectué de manière automatique (éventuellement de manière transparente sans utilisation d'une interface utilisateur) à partir d'une source configurée par avance par le fabricant, le distributeur ou un autre acteur de la vie du produit. Cette source peut être un site Web prévu à cet effet. Sur la Figure 2, l'Appareil 10 est connecté à un serveur distant 30, depuis lequel ledit Appareil 10 télécharge le Logiciel Supplémentaire.If the Additional Software is not present on the Device 20, if it is altered or obsolete, the Device 10 proceeds to the loading of the Additional Software directly in the Device 20, or indirectly through the Apparatus 10. This loading can may be done using an internet network connection. Downloading the Additional Software to the Device is illustrated (step 05) Figure 1. Loading the Additional Software can be done automatically (possibly transparently without the use of a user interface) from a source configured in advance by the manufacturer, the distributor or another player in the life of the product. This source may be a website provided for this purpose. In Figure 2, the apparatus 10 is connected to a remote server 30, from which said apparatus 10 downloads the additional software.
L'identifiant propre au protocole, décrit ci- dessus au paragraphe 1) peut être utilisé pour choisir quel type de logiciel doit être chargé automatiquement et installé sur le Périphérique 20.The protocol-specific identifier, described above in paragraph 1) can be used to choose which type of software should be loaded automatically and installed on Device 20.
3) Exécution du Logiciel Supplémentaire : Les fonctions supplémentaires sont activées et peuvent démarrer, grâce à l'exécution du Logiciel3) Running the Additional Software: Additional features are enabled and can start, by running the Software
Supplémentaire à partir du Périphérique 20, éventuellement de manière collaborative avec les moyens logiciels et matériels de l'Appareil 10.

Downloading the Additional Software is shown
(étape 06) Figure 1.(step 06) Figure 1.
Classiquement, le logiciel du Périphérique 20 utilise des fonctions ou des moyens logiciels mis à disposition par le logiciel de l'Appareil 10. Le système d'exploitation fournit ainsi des services au logiciel supplémentaire (exemples : connexion réseau, accès aux mémoires, ordonnancement ...) . De plus, le logiciel du Périphérique 20 et le logiciel de l'Appareil 10 partagent des ressources matérielles (processeurs de l'Appareil, mémoires volatiles ou non ... ) .Conventionally, the software of Device 20 uses functions or software means made available by the software of the apparatus 10. The operating system thus provides services to the additional software (examples: network connection, access to memories, scheduling. ..). In addition, the software of the Device 20 and the software of the Device 10 share hardware resources (processors of the device, volatile memories or not ...).
Lorsque le Périphérique 20 est détaché de l'Appareil 10, Le Logiciel Supplémentaire peut être conservé sur le Périphérique 20, de sorte que l'utilisation puisse être plus rapide lors des utilisations ultérieures. Le débranchement du Périphérique est représenté (étape 07) Figure 1.When the Device 20 is detached from the Device 10, the Additional Software can be stored on the Device 20, so that the use can be faster for subsequent uses.

L'Appareil 10 peut conserver pour des raisons de sécurité un "hash" (ou empreinte) du Logiciel Supplémentaire stocké, pour s'assurer qu'aucun utilisateur n'a modifié le Logiciel Supplémentaire (à des fins malicieuses par exemple) .Apparatus 10 may retain for security reasons a "hash" (or fingerprint) of the stored Additional Software, to ensure that no user has modified the Additional Software (for malicious purposes for example).
Le Logiciel Supplémentaire peut éventuellement être chargé dans le Périphérique 20 uniquement la première fois que le Périphérique 20 est rattaché à l'Appareil 10, de sorte que l'utilisation peut être plus rapide pour les utilisations ultérieures.The Additional Software may optionally be loaded into Device 20 only the first time Device 20 is attached to the Device 10, so that usage may be faster for subsequent uses.
Si certaines fonctionnalités supplémentaires sont optionnelles, le choix (éventuellement préalable) de l'utilisateur de les activer ou non peut éventuellement déclencher le chargement d'un ou plusieurs modules de Logiciel Supplémentaire.If certain additional functionalities are optional, the choice (if necessary) of the user to activate them or not may possibly trigger the loading of one or more additional software modules.
L' invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de l'invention sans pour autant sortir du cadre du brevet. The invention is described in the foregoing by way of example.
