If you are planning an application which requires multiple TVs - you will like this Section of the ABTEC website.
The typical Commercial TV System for a Restaurant, Tavern or Sports Bar consists of pictures 'coming in' from several sources. Most often, CableVision is one source - or an Outside TV Antenna - and almost
always there is some form of Direct Broadcast Satellite equipment involved.
The customers want to see Top Quality Pictures on every TV - and having lots of TVs with good pictures means that some level of distribution engineering must be applied. The Owners and Management want a system that is easy to use - and one that is not troublesome to operate. The easiest way to accomplish all of this is to incorporate a system that 'blends' the extra channels [like from DTV or Dish Network] into the usual line-up of daytime pictures [ie., Cable]. This is most often accomplished by 'modulating' the extra pictures onto a channel not consumed by Cable. Components required are a certain set of Filters, a good Distribution Amplifier and Quality Modulators to 'Insert' the locally made pictures from the Satellites. I mean ... you cannot just go plug all the wires together and put more aluminum foil on the 'rabbit ears' - some electronic components are needed ! And proven engineering makes it work. The following chart shows the components ABTEC most often uses in the design and installation of our Custom Built - Multi Source - Distributed TV Systems..
