G+_James Nennemann Posted July 29, 2016 Share Posted July 29, 2016 I need to Know How to send the same video feed to multiple TVs, the cheapest, but most HD way possible. If I was in the UK or one of many other countries with DVB-T I would send it all over coaxial with a little 1 channel modulator for about $200. But after doing some research, our TVs in the US use ATSC, which must have modulators made of gold. Help! I just want to send a simple HD feed to many HDTVs, at various dozens of meters apart.

G+_Ben Reese Posted July 29, 2016 Share Posted July 29, 2016 I Know How via IP if they don't have to stay in sync. A little latency, though, so may not be what you need. Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 29, 2016 Share Posted July 29, 2016 whats the input? If just a simple composite, I'd think you could get a multiplexer. HDMI will have that HDCP (sp?) DRM junk. Component might be able to multiplex. Do a search for video multiplexers. Link to comment Share on other sites More sharing options...
G+_Robert Hafer Posted July 29, 2016 Share Posted July 29, 2016 Yeah, NTSC was much easier than ATSC. Have you thought of something like a chromecast or roku for streaming? It might end up being cheaper depending on your set up. Link to comment Share on other sites More sharing options...
G+_Stede Bonnett Posted July 29, 2016 Share Posted July 29, 2016 HDMI splitter? Monoprice has a 1x8 for like $90. If you are running long distances there are powered splitters and redmere cables. For distances over 30 meters though you are going to need HDbaseT or slmilar and a set of that gear would be over $1k Link to comment Share on other sites More sharing options...
G+_James Nennemann Posted August 1, 2016 Author Share Posted August 1, 2016 I have looked at Chromecasting via AirParrot, or similar software. The limitation is 4 tvs and there can be issues with wifi at times that could be an issue. I am presently using an HDMI splitter for 2 tvs, but I don't want media converters at each end for every TV I add, and wouldn't it be so wonderful if you could buy a $200 ATSC modulator?... just keep plugging in TVs... even get 2 or more and have multiple channels. Even better, I have read that you can set up a sub-100mW transmitter and send a digital broadcast to those TVs in range. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted August 1, 2016 Share Posted August 1, 2016 I'm sure media companies put a lot of pressure on manufactures to keep prices high. Best bet would probably be something used. Maybe at an auction site? Cheapest I found on Amazon is ~600: https://www.amazon.com/gp/product/B00KFS1Z56 Have you looked at SDI? I know little about it, but I think it can run long distances and it looks like splitters are fairly inexpensive. Would just need a way to get the video signal into SDI then converter boxes at each display to convert back to HDMI. Monoprice appears to have lots of SDI equipment. HDMI to SDI ($60): http://www.monoprice.com/product?p_id=145321x8 SDI Splitter ($60): http://www.monoprice.com/product?p_id=10323 SDI to HDMI ($80): http://www.monoprice.com/product?p_id=14531 According to this: http://articles.triplewidemedia.com/choosing-right-video-cable-sdi/, SDI is typically run over RG6 - which is a good thing since it's common and relatively cheap (~$0.15/ft on monoprice and available everywhere else too). Not quite as convenient or as cheap as a $200 modulator, but shouldn't be too difficult to implement. Link to comment Share on other sites More sharing options...
G+_Rick A Posted August 5, 2016 Share Posted August 5, 2016 James, are the tv's in the picture the ones you wish to display on.? if so ten HDMI is overkill. you should be able to get a cheap tv broadcasting unit that goes out on ch3 or 4. the TV's shown will all pick that up with a simple 6 IN antenna.
