DEVICE AND METHOD FOR STORING AUDIO/VIDEO DATA IN A HOME NETWORK
First Claim
1. A device, referred to as set-top box, comprising:
- means for receiving audio/video data transmitted via a communication medium,at least one application using said received audio/video data and necessitating their storage prior to their use, the application comprising means for issuing requests for storage/retrieval of the received data,storage means comprising;
means for connection to at least one peripheral storage unit which is capable of physically storing audio/video data,means for detecting peripheral equipment co-operating with said connection means for detecting the presence of peripheral storage units as from their connection/disconnection to/from the set-top box,control means co-operating with the detection means for receiving said requests for storage/retrieval of data issued by the application and for controlling the assignment of physical storage addresses in the different peripheral storage units which are present,software storage means co-operating with said control means for preserving and retrieving the physical addresses of the data stored in the different peripheral storage units.

Abstract
The invention relates to a method and a device for storing audio/video data in a home network. They allow addition of storage possibilities to apparatuses of the set-top box type which do not have or cannot develop them so as to extend the functionality of the apparatus without a software update, dependent on connections/disconnections of peripheral storage equipment. To this end, the invention provides a virtual management of the storage possibilities within one and the same apparatus. An abstraction layer is realized above the physical storage support by software storage means co-operating with control means so as to hide details on the used peripheral storage unit or units from the application. For an application requiring storage of audio/video data, the operation is transparent. The peripheral storage units are detected when they are “hot”, dependent on their connection/disconnection, and are taken into account by the control means at the level of the available storage capacity. The application conducts a dialogue only with a single interface for its storage needs, while the control means co-operate with the software storage means for managing the transfer of data to and from the different peripheral storage units.

10. A storage method comprising the steps of:
-
detecting peripheral equipment for detecting the presence of peripheral storage units as from their connection/disconnection to/from a set-top box, receiving a request for storage/retrieval of audio/video data issued by an application using said audio/video data and necessitating their storage prior to their use, controlling the assignment of physical storage addresses in the different peripheral storage units that are detected, and software storage for preserving and retrieving the physical addresses of the data stored in the different peripheral storage units.
