MULTIMEDIA INTERFACES FOR HOME AUTOMATION SYSTEMS The present invention refers to a series of multimedia interfaces for home automation system.

More in particular, the multimedia interfaces according to the invention allow sharing and exchanging multimedia contents and controls between a home automation system, multimedia objects and an Ethernet network, with the aim of creating, from the user's point of view, a single system manageable and accessible from any point, in all its functions (including the multimedia ones) following the same requirements and with the same interface devices or with interfaces suitably adapted to the dimensions and types of visualisation screens or displays used. Currently, there are various devices capable of transferring multimedia contents from the Ethernet or Internet network to a multimedia object, such as, for example, the Internet TV service "set top box" modems. There are some devices capable transferring multimedia contents in two or more directions simultaneously, such as, for example, the new satellite decoders which allow sending the decoded signals towards the television or towards the Ethernet and/or Fire Wire (Wi-FI) network. Furthermore, there are some technologies which allow sharing of multimedia contents on homogeneous networks, such as, for example, sharing multimedia contents on an

LAN network with the media centre services. Lastly, there are some devices which allow controlling and supervising the home automation systems using multimedia objects (such as a television) or remotely, using the Ethernet network or the Internet network (typically via gateway or web server) .

An objective of the present invention is that of providing a series of multimedia interfaces for home automation systems, capable of allowing sharing and exchanging multimedia contents and controls between a home automation system, and a series of multimedia objects and a network, such as, typically, and Ethernet network. Another objective of the present invention is that of providing a series of multimedia interfaces for home automation systems, capable of allowing to create, from the user's point of view, a single system manageable and accessible from any point, in all its functions, including the multimedia ones, with the same requirements and the same interface devices or interface devices suitably adapted to the dimensions and to the type of visualisation screens used.

Another objective of the present invention is that of providing a series of multimedia interfaces for home automation systems, extremely reliable and functional, with respect to the known art.

These and other objectives, according to the present invention, are obtained by making a series of multimedia interfaces for home automation systems, according to claim 1 attached; other detailed technical characteristics are provided for in the subsequent claims .

In an advantageous manner, the interface devices subject of the present invention allow sharing and exchanging multimedia contents, such as audio and video, analogue and/or digital signals from and towards an Ethernet wire network or based on radio frequency (WAN, LAN, HAN, etc) , as series of objects generally referred to as multimedia (such as televisions, DVDs, satellite decoders, digital terrestrial decoders, music players etc) and a home automation system made through the BUS technology (for example "multimedia" SCS BUS). Such interface devices allow activating and controlling the multimedia objects alongside controlling and supervising the home automation system connected to them.

According to the invention, it is further possible to generate one or more interfaces for controlling and supervising, both the home automation system, and the multimedia contents of the system; such solution is obtained by connecting the interface device subject of the invention to the home automation system and/or to

the multimedia objects and/or to the Ethernet network. Lastly, the interface devices described in the present invention allow converting a television or any other multimedia object into a video-communication, video- intercom, or video-telephone point, simply by adding a microphone, connected directly or via radio.
