There are plenty of posts on how long can RCA runs before
degradation...etc.
My specific situation is this: A video camcorder (DV or Hi8) will be
shooting (record or not) in a gym. The video signal is intended to be
displayed in another room within the same building but with a distance
of about 80-120 feet (cable run). The display will be either a 27" TV
or a DLP projector (at 40-60"). The purpose is to allow people who are
sitting in the room to observe (video/audio) the performance (dance,
singing) happening in the gym.
I'll say the quality expected is no where needed to be broadcast/pro
but good enough to allow people in the room to enjoy the performance.
What is the most economic way to achieve this?
I think the video can be sent through RCA composite (yello/red/white)
for quite some distance, but the audio probably can't. Some people
suggest using a DI and run balance for the audio part, or some
transformer and phone wire (which I don't understand). I'm pondering
modulating both audio/video signals to RF and use tv-cable and use a
demodulator (VCR) at the other end. Another guy suggest using those
2.4GHz wireless sender/receiver, but I think it's not gonna work as
there're too many concrete walls in between plus it's suspectible to
interference when there're people walking around.
My key is low cost and good enough to have a 'tv-signal-quality'
experience.
How about computer at both end using ethernet.... too weird
Thanks....
