SIGNAL SPECIFICAtIoNS

7.3 tV tECHNICAL SPECIFICAtIoNS

The TV signal source is either analog or digital. It is likely the source is already configured for the facility. If not, see the following.
Analog
If the facility has traditional cable TV (analog) the coaxial cable can be run directly to the Netpulse screens and connect to the coaxial connector
on the back of the screen.
Analog TV signal must be tested at each coax cable termination and tuned to fall within the range of -4dB and -12dB signal loss.
digital
If the facility has digital cable or satellite TV service (Dish or DirecTV) which requires a box from the cable / satellite provider to view the signal
a head-end will need to be in place to be able to view and change all TV channels from the Netpulse screens (or any personal screen device). A
local Audio Visual contractor will easily be able to create a system.
a. As many cable / satellite boxes as channels will be needed to display in the club. If 8 channels are needed then 8 boxes are needed. The
individual channel chosen ( e.g. – ESPN) can be changed at any time but additional boxes may be required to have additional channels.
b. The output of each of these boxes will go into a modulator that will assign a channel number for each box. This is the channel chosen from
the TV or Netpulse screen. So for example, in the below figure select channel 7 to view CBS since the box with CBS has been assigned to
channel 7.
c. The signal from each modulator will then be combined (via a combiner) into a single coaxial cable.
d. The coaxial cable will now contain all the channels in the system and can be run to anywhere in the facility and displayed on any TV
(including) the Netpulse screens.
