If they are buying 50" sets, wouldn't plasma screen be cheaper ?

Yep. We are getting Plasma's now. Much cheaper compared to LCD's. 60" LG for $1400 from HN because we are buying 4.

You can get wireless media splitters...

There are some real good ones around that i tested and they had very good range, im not sure on these specific ones. and you can plug them into a PC also so... problem solved? :D

Analog composite junk, using 2.4GHz.

There are wireless HDMI solutions but they are expensive and short range.

As far as i can tell he is not wanting to play HDMI movies for all to watch just adds and if he wants to do it on the cheap why go all out?

Because all that you will get out of an analog video sender in any urban environment is a flickering mess of static with all the bluetooth, wifi, people cooking etc cluttering up the band.

When a video sender cannot operate across a house, what hope do they have in a commercial establishment?

If you are playing ads etc you want them to look as sharp and clear as possible, not a fuzzy SD image, so even sending composite etc video over cables is not really a viable solution.

Will not be playing any HD stuff at all but that could change in the future. Price is not an issue for the company. jinz1's linked Atlona's products and CYaBro's linked mediasignage software is perfect. Being a big company, we certainly do not want to implement cheap hacks that I know will work but we would like to keep it tidy over all.

To be fair you probably are, given you're likely to be sending computer resolution images to a plasma or lcd screen? This is likely to be fairly high/above SD even at basic monitor resolution settings.

Jaycar sells a small HDMI extender for $30 that will do 60m, item code AC1698, but I don't expect too much from it. They also sell an HDMI 1.3 over Cat5 extender for $205 that will do 1080i over 60m and 1080p over 40m, item code AC1689, and includes an IR extender so you can remote control the TVs.

Stay far away from consumer wireless solutions, and don't expect to find much pro quality wireless equipment locally. The market here is way too small.

You are likely to find some good brand name products from overseas. If cost is not really an issue, then one option is www.partsexpress.com which used to do economy air mail but for the past few years only Fedex. In the past I've ordered a number of expensive times from them. Their new(ish) international shipping policy means they lost my business.

For private importing, duty is only GST, only paid if more than $50 duty, and only if customs desice to check your parcel. I think for business it is the same, but you are guaranteed that customs will screen your product to see if duty is payable.

If you buy a TV model that has a network port and DLNA receiver support (should be many models these days) can't you have have a server use DLNA push to send the content/video over regular cat5e/ethernet?

Yep we can and this setup is/was also on the list, however this is our backup/secondary route if the above suggestions fail to impress or work. We would rather not have a streaming solution even though we can create a seperate VLAN on the network so that it does not eats up all the bandwidth of our local domain network. DLNA streaming is our backup and last resort solution.

If you need a professional solution, in my opinion you've 2 options to look after:

1. Look for "special" panels (LCD to other) with a built in "digital signage" client and a centralised management software.
Panels and management server are connected through the network (no hassling with extensions on VGA, HDMI or whatever).
NEC and Samsung, I do know, have this.
Advantage: neat solution (no external player and no extra cables).
The panel vendor might also give you the management software (at least the basics) for free.
Disadvantage; you are tied to the panel vendor

2. A digital signage solution provider can sell you standard panels, connected to a player (at the rear of the panel).
That player is connected with a centralised management server through the data-network.
Scala is a well known vendor of players and software, but I'm sure you will find others as well (mostly based on OEM hardware).
Otherwise you might be looking first for a goo solution provider rather than looking for solutions yourself.
Advantage of this type of solutions: you're absolutely free to use panels of your own choice.
Disadvantage: 2 peace hardware for each panel is less neat and they both have to be powered (one more power connection)
