Hi people, I have an application installed on a PC which generates about 10 graphs of real time data, I would like to output these graphs to about 4 sony bravia TVs. My preliminary investigations indicate that a video splitter would do that. I have never used one before, any skunks with more details? Any local suppliers? What if I wanted to have the 10 graphs be like kawaida TV channels so that I can tell users something like; "Switch to channel 5 to see report X", any leads on I can do that? Thanks!
Hi Peter, Most of the LCD and Plasma TVs these days have inputs ( db 15 connector ). If you use eg M$ on a desktop with an AGP card with 2 outputs, use extended desktop to output to 2 screen and a splitter to output to 4. Or you may just get a 4 port AGP card that will handle this. ( This concept is similar to creating a Video Wall ). The entire 4 screens will appear as one and you can display the grahps accordingly. A splitter will create 4 views of the same output. On creating RF channels, you must first create 10 outputs with the separate graph. each output will deliver AV signals. Then use RF modulators to convert the AV signal to RF channels over the same co-axial cable. The RF modulator allows channel selection and each TV can be tuned. This is called MATV and common concept in hotels, apartments etc. Availability of modulators is from any supplier who does installations of Sat dish etc. HTH's Rgds.
sorry, I forgot to add. If you use the RF option, remember per metre of cable/per connector there is insertion loss in db. So keep distance from AV outputs to Screens under 2 metres. Else, if they are at a distance, use a mast-head amp ( 115 db ) to an attenuator. Esle you may get shadows and cross talk. :-)
Ok, thanks. Based on your suggestions, I think I'ld rather go the video splitter way, it seems "simpler", plus the TVs are like in a 10 metre radius. Whats the average cost of a 4 port video splitter? I think I would also need long VGA cables, any supplier you can recommend? On Mon, Jun 29, 2009 at 5:52 PM, aki <aki275@googlemail.com> wrote:

Sounds as if you need multiple graphics cards or cards with multiple GPU (cards that have 2 or 4 monitor (DVI/VGA) ports). Mullard Electronics(http://www.mullard.co.ke/index.php/contact-us) used to have these. ________________________________ From: Peter Karunyu <pkarunyu@gmail.com> To: Skunkworks forum <skunkworks@lists.my.co.ke> Sent: Monday, June 29, 2009 10:25:47 AM Subject: [Skunkworks] PC to TV video splitters Hi people, I have an application installed on a PC which generates about 10 graphs of real time data, I would like to output these graphs to about 4 sony bravia TVs.
