Church Sound & Video Tips > Video Tips > Feeding Computer Video to TV
We need to feed computer video to a projector as well as TV monitors, how can we do this?
Computer Video Signal:
Computer video is not a composite video signal. In order to feed computer video to TV monitors or VCRs, you need to connect through a Scan Converter. These can cost several thousand dollars. Alectro Systems sells a very economical yet high quality unit (model 444-3700). In a typical church video projection configuration, you connect from the computer to a VP-2xl or VP-400 distribution amplifier. Plug one output of the amplifier into the video projector and plug another output into the scan converter. The output from the scan converter is an RCA jack which connects to the Video Input on the TV monitor(s).
444-3700 Scan converter
The
444-3700
Scan Converter converts Computer video into Composite video
which is compatible with TVs, VCRs, video mixers, etc.
You need this to send computer images to TV monitors
VP-2XL VGA Distribution Amplifier With Gain
The
VP-2XL
is a one in, two out Computer Video Distribution amplifier with
gain. It can be used to send the computer video signal to two devices
such as a computer monitor and video projector. Because it has adjustable
gain, it can also boost the signal to compensate for long projector
cable runs. The gain can also brighten a projector image if required.
VP-400 4 way VGA Distribution Amplifier
The
VP-400N is a one in, four out Computer Video Distribution amplifier.
It will take the computer video and send it to up to four devices
such as projectors, computer monitors and scan converters.
If you are feeding composite video to several TV monitors, you will need to amplify the signal using a 105VB Composite Video amplifier. This will boost the signal strength to give a clear picture without snow.
DA-500A Composite Video Amplifier
The DA-500A will amplify an RF Modulated Video signal to allow you to split it into several TVs.
A composite video switch such as the BT943 can be added to the system to switch the
TVs from compute to VCR, DVD or Camera video.
