"I recently did a Multi-Floor Media Display Network installation of remote high-resolution video displays with accompanying audio feed in lobby areas on two separate floors of a Government Agency’s district office. The Commander wanted the ability to screen live satellite feeds, CCTV, local network information as well as a variety of in house presentations.
To accomplish this, I needed to create a PC head end with software and other equipment capable of managing the various inputs. Select an output device that could be wall mounted in the space available and be able to reproduce VGA signals at a resolution of 1280x1024 as well as video and CCTV images. The monitor would need extremely wide viewing angles to allow for public viewing. Audio would need to be accomplished by a network of speakers balanced to compensate for the losses due to distance.
The head end equipment selected allowed inputs for DVD, VHS, satellite, CATV, Internet and LAN feeds. The signals were fed through a video processor which added additional features like picture-in-picture, freeze frame and zoom, as well as the ability to remotely control which one of the inputs would play the primary role on each screen. Since the monitors were to be located on different floors and in areas remote to the head end, Cat5 VGA extenders were used to insure distance, 600 feet, and resolution, 1280x1024. The ST-C5VA-600 and ST-C5V-600 products manufactured by Network Technologies Incorporated (NTI™) were used to accomplish this."
