Abstract: A system for monitoring television signals broadcast by at least one transmission antenna in a broadcast area includes a monitoring control center and a plurality of remote monitoring units distributed in television signal receiving locations of the broadcast area remote from the transmission antenna. The remote monitoring units are configured to receive the television signals irradiated in the respective locations, process the television signals and send to the monitoring control center information related to the processed television signal. In particular, the remote monitoring units include a receiver adapted to receive the television signal, a measuring system adapted to perform measures on radio-electric features of the received television signal, and a communication system adapted to communicate measurement results to the remote monitoring center, exploiting a communication link between the remote monitoring unit and the control center.

Abstract: The video control circuit is particularly adapted to multimedia applicati, wherein image transmission services are offered in addition to usual telephone speech and data transmission services. The circuit is capable of processing both photographic and graphic video images, satisfying both the relevant CCIR standards and the specifications proper to personal computers, VGA EGA, etc. so as to allow the representation of either types of images on an only type of display. To this end, it generates both timings proper to the CCIR standards, for a resolution of 720 columns per 480 lines, with an upper representation limit of graphic planes of 1024 columns per 1024 lines.
