ITV-telearch an architecture for enabling device telecontrol and sensor data access over IDTV systems.

Our work provides the specification and implementation of a communication mechanism between broadcast content viewers and interaction devices or sensors placed on the scenario of a live video show. This solution was designed using middleware based architecture and interconnects the devices and sensors of a broadcast program environment in a device network. By using the proposed architecture, the viewers will be able to see the real world interaction devices and control them through interactive applications using specific APIs to each broadcast system. So this approach is able to manage the devices in the network despite of the physical layer used to communicate, allowing them to communicate to each other and to be controlled by external applications. Afterwards, by using the architecture, we can allow viewers to control or access data from entities which compound the network through distributed communication processes and control applications. In order to validate our work we present a test scenario where a mobile robot with a set of sensors is added to our architecture and controlled by the viewers.
