Question about the AEI Digisender Gold (RGB Capability)

Question about the AEI Digisender Gold

I'm considering getting an AEI Digisender TM Gold for 179.99 Argos - people here seem to have given them a fairly decent reviews.
I have a question on whether it will do the job I have in mind - hopefully someone here can comment.

What I want to do is as follows:

I only have 1 coax feed from my attic to my main living room TV point :-(
Currently this coax is being fed from the LNB output of a Sky dish pointing at 28.8E going to a Panasonic DSB30 Digibox + FTV.
I'm using the Digibox in RGB mode, outputting to RGB Scart and on to a J.S. RGB to VGA convertor box and finally on to a 42" Plasma Display.


I've added another dish and receiver (Lidl 80cm dish and Comag SL55 - a very versatile receiver ;-) ) pointing at Hotbird 13E.
I've brought this Hotbird feed as far as the Comag Reciver in an upstairs bedroom where I can view it on a portable.
Now I want to "send" the output of the SL55 receiver to my TV downstairs?

What I want to know is this:

Can I select an RGB output from the Comag SL55, and if I use this AEI Digi Sender, will I still be able to "see" an RGB signal at the receiver end of the Digisender - that I can then connect to the RGB-VGA convertor box ??

Hope someone can help.

Thanks in advance

At that price, it should be good. I paid €99 for a Trust kit and am very satsified with it. But....I suspect all of these senders are based on composite (CVBS) rather than RGB, so you should double-check that the sender is RGB.

Going RGB-VGA is odd, is that because the RGB input is being used for something else?

No legal CE video sender does RGB. They *ALL* use the same CE licence, which is one of 4 forward channels, using a signal like Analog Satellite signal, but on 2.4Ghz, and a single reverse channel for IR control about 433MHz. If it does RGB it isn't a video sender.

The ONLY difference between a €99 sender and an expensive Philips is ability to remote select from up to 4 SCART inputs. If you want a single video feed the extra money is wasted.

The Thomson and Lidl senders I have do identical quality, which is stereo audio (ordinary TV RF from any local sat box is always mono) and quality of video / audio indistingusable from Composite SCART.

Cyclopath2001, my plasma only has a VGA input as standard. (Panasonic TH42PWD6) So I have to convert from RGB to VGA to get my Digibox to work
with it. Other Panasonic input boards are available, like SCART RGB, Component, DVI etc
I actually have a DVI board that I haven't used yet.

So folks, other than buy a Composite to RGB converter box, is there any other way to accomplish the scenario I describe above?

Are there any Amps or DVD Recorders that have converter technology built into them? I was thinking of buying one of these anyway?

Cheers,

VGA is actually RGB. You can wire a RGB SCART to VGA direct.

But it may not work. On some Projectors with Composite Video and VGA inputs it does work.

This is because the minimum VGA resolution & refresh rate is exactly twice the NTSC line (horizontal) frequency, similar to PAL, about 15.5kHz approx. The minimum VGA line rate is 31kHz.

You may need a Composite to VGA convertor (basically a PAL decoder), for the video sender and then a SCART to VGA frame convertor or the SCART board for the Plasma screen.

I would think it possible the proper SCART board does PAL decode from composite also, or a version that does is available. Many sources inherently can't be RGB.

Try www.maplin.co.uk for a Composite to VGA (typically €200) or Composite to SCART RGB (typically €100).

Thanks Watty, I knew someone on boards would have useful input (pardon the pun )

I chose the J.S. RGB to VGA convertor box over the standard Panasonic Scart input board on the strength of reviews of both on AVForums UK.
Basically, people there disliked the Panny board, citing poorer overall performance on an otherwise excellent display.
My only option may be to go back and buy it! Its the first board mentioned here- along with all the others available:

http://www.av-sales.com/plasma/html/panasonic_plasma_terminal_boar.html

So if I understand correctly, if I "digisend" a composite output from the output of the Comag SL55, and plug the output of the digisender receiver into this Panasonic Scart board, the board should pick up the signal and display on the Plasma?

Thanks in advance for your help,

One final question on this:

A CAT5 link exists between the Comag SL55 and my Plasma TV point.
How easy or successful would it be to send the Comag SL55 RGB output over CAT5 from point A to point B assuming the distance is approximately 20m.

What equipment would I need - and what cost would be involved?

Ive always thought the term "digisender" rather misleading as it suggests that the signal is transmitted digally wheras in fact most (all ?) of them use analouge FM

The only way you could have seperate RGB signals if a digital signal was used although AFIK there are no true "digisenders" on the market

yet..........................

Can someone please explain how this is? You have a transmitter with two scarts...one connects to ntl and dvd lets say...this is then send to receiver...now how do u conect the other two av items like a cctv and a video from the trans if there is only two scarts?
How can I setup one dvd player in main room where trans is so that I can watch on both tv's? What I mean is dvd player has one scart connection do I plus trans into this or main tv?

Well there are IP WifI video senders but about 400 Euro and poorer quality due to the compression.

The ones under 300 are all composite video only to ananlogue FM. But If you had four of them on ch A, B, C and D and wired the SCART you can do RGB and 5.1 analog sound feed (Actually 8 analog channels).

any other places that do scart to VGA (10M) Watty, maplins way expensive

Most VGA monitors can't do 25i
So good SCART to VGA units de-interlace which is expensive.

Many Videosenders have a pass through scart connector.

It does not need to de interlace, just a straight scart to vga cable
