I'm looking to pipe my audio and video signals to rooms other than where the source is. Video includes DVD.

Which has the better quality, the wireless 900mhz, 2.4ghz or wired using the phone line?

Are there any other pros and cons??

Thanks,

Frank

I've used several of the wireless units in the past
with good results. Unfortunately, recently the wireless
solution has been plagued with annoying pops. Considering
the cordless phones and wireless pc networking I have,
it's not too surprising. I ordered the leapfrog unit
yesterday and am expecting delivery tomorrow. I should
have a chance to test it out within a few days. Will
give you an update when I do.

Thanks, there's nothing like some actual use...

BTW, we have several 900mhz phones and baby monitors and one 2.4ghz phone.

Well, initial results were mixed. I first hooked up the leapfrog
between to two locations I wanted to go between and used a standard
(supplied) phone cord to connect to the wall jack. The audio was
fine, but the picture was unacceptable. Next, in order to see just
what the technology was capable of, I connected the units back to
back with about a 3 foot normal phone cord. The result was
suprisingly good.

I switched back and forth between a direct rca cable connection and
the leapfrog connection (using a second receiver input so I could
switch quickly) and had to look real close to see any noticeable
difference. For the record, I was using a Pioneer 50" plasma display
and Sony Satellite and DVD for sources.

To let you know, my house is wired with Cat 5 cable (for phone and data
connections) to at least 20 outlets in a home run (or star) configuration.
All of the outlets are currently tied in parallel at the wiring hub.
I also have a DSL connection. The DSL is split at the entrance to the
house onto one of the other four pairs of the cat 5 cable so that I
don't have to filter every phone jack that I hook up a normal phone
to.

Although the leapfrog advertises that it works with phone and data
connections on the same wire, I am assuming that my DSL or wiring
configuration is causing it trouble.

Tomorrow I plan on making some modified phone cords
which will allow me to connect it to one of the
other two pairs that are not connected to any DSL or filtering
circuitry. If I am still having trouble, I may try directly
connecting the two outlets at the wiring hub so that the signal
is not loaded by all of the other outlets in the house. And
as a last resort, I have a spare coax run (or can free one up
easily) that I may try to run the signal over.

Will update as I continue.

Thanks for all the hard work.

I have Cat 5 running to most rooms as well, but just for data. Seperate 4 wire phone service with nothing else over it was what I'm planning.

I'm planning on having the two receivers so running a second phone line to both locations would be a pain. I'd REALLY like to use the existing wiring. And if the over wire solution doesn't deliver an exceptable picture, use the wireless...

I really like the two way infrared though. It seems there's never a best/simple solution...

After trying one of the unused pairs of my cat 5 cable
with only minor improvement, I got impatient and went
straight for the dedicated coax run (using leapfrog).

The results were much improved but still not as good
as what I had seen with only a short phone cord between
the units. I would rate the picture (w/coax) as usable
but not something I would want to use on a daily basis.
(At least not at close range with a large screen.)

In my situation, I don't expect to use it that often
and when I do, it will mostly be for manipulating
menu screens for a CD changer. On rare occasion
maybe a DVD movie. As such, I think this will work
for me.

When the wireless unit is not experiencing interference,
I believe it definately to be the better of the two.
It also (on select models) will pass infrared back to
the source components. (Most setups don't require
"two-way" IR).

I know this probably hasn't provided much expectation
that either will work for you. If you're viewing
on smaller screens, then it should appear somewhat
better. I would say on a 25 to 32" unit at a resonable
distance, things would be fine. On any large screen
TV, I would think twice about the leapfrog.

Good luck,
George

I have the 2.4 unit but when I put
a wireless access point for my
ethernet (linksys...which I love)
I started getting distinct white bar-like
interference,

Ordered the Leapfrog. Hope springs
eternal.

Well.. I got the Terk Leapfrog...hooked it
up and it SUCKS. Rarely do you hear me
say anything negative about anything....but
it SUCKS.

Its probably my own fault as I have several things
running through my phone lines--so maybe this
unti does work elsewhere.

Meanwhile, the 2.4 picture and sound are
superb, and I only get the quick
interference when my wireless network
card talks to the access point. (I had
to move the access point a ways away from
the 2.4 sender and receiver though.

So now I'm stuck. I too have ethernet
(cat 5) running around, but the leapfrog
didn't work there as you found out too.

So now what?

Hey...Look at this at www.hometech.com

Over Cat5!!!

Audio/Video Over Twisted-Pair

http://www.hometech.com/audio/tpaudio.html

This page describes a device that allows you to send baseband video and left and right audio over twisted-pair category 5 cable up to 2000 feet.
Video/Audio To Twisted-Pair Adapter
Balanced Line Driver/Receiver -- High Quality Audio Over Twisted-Pair



Video/Audio To Twisted-Pair Adapter
Built-in impedance matching device and filter for baseband video channel signal transmission over inexpensive Category 5 UTP cable.
Handles either NTSC or PAL video signal.
Two audio channels can be used for high-fidelity stereo audio signal.
Easy installation with existing premis wiring and wall jacks.
Interface:
Video: One BNC female connector
Audio: Two phono jack connectors
RJ-45 Signal:
Video: Pair 4 - Pins 7 & 8
Audio/L: Pair 3 - Pins 3 & 6
Audio/R: Pair 2 - Pins 1 & 2
Impedance:
Video: 100 ohm Balanced
Audio: 600 ohm Balanced
Bandwidth:
Video: DC - 12 MHz
Audio: 50Hz - 15 KHz
Distance:
Color Video: UTP Category 5 cable: Maximum length 1,000 ft.
B&W Video: UPT Category 5 cable: Maximum length 2,000 ft.
Enclosure: Black PVC
2.2"W x 3.03"L x 0.98"H
No external power required!

This clever little box allows you to send a baseband video signal and a pair of audio signals over a standard category 5 cable, without worrying about noise, hum, and other forms of interference. It takes two of these devices, one on each end, to send a signal. And it takes one pair in the Cat 5 cable for each of the video and audio signals. We don't really recommend creating a whole-house audio/video distribution system out of these devices...but when you get stuck, they can bail you out and get that signal from point A to point B.
