Thread: Digital ATSC RF Modulator

Ok guys, i figured if anyone may know the answer to my question it would be you guys.

I have 4 HD Tivos with D* and I want to be able to view them on any of my 5 HDTVs in the house. So I was wondering if there is any available 4 channel ATSC Modulators available or something that could make this work. All the TVs have a tuner so i figured it would be easiest to set up like I did with the old RF systems I've used before. Price isn't really a problem if it's like a couple of thousand dollars not a problem. I just want all tvs to access all 4 tivos in HD.

Ive been trying to find one and cant. Not a "consumer" one anyway.

probably a long way off since atsc doesn't offer have copy protection. If it had component inputs it would need to be able to encode hd quality mpeg2.

It did exist once though as the Dish 5000 HD modulator.

You cant modulate and get HD picture, your best bet is to house all HD rcvrs in 1 location and get a video switcher (ELAN v-883) you can switch any video source (hd tivo) to any location, so long as you have a set of component cables from the switcher to each TV.
The v-883 will give you 8 hd inputs and 8 outputs all controllable by ir commands, these are used in centralized rack systems for whole house A/V.

Featuring eight sets of component video inputs and outputs, the V883 lets users stream all of their component video sources, such as DVD, DVR, satellite TV and more, independently to up to eight different TVs and/or monitors in as many rooms. The V883’s unity gain design and high definition chip set ensures that whatever content is piped into the V883 is delivered to its viewing destination with the exact same quality generated at its source. The V883 also distributes standard composite video from non-component sources such as CCTV cameras and VCRs.

the question wasn't for another way to wire the whole house the question was where do you get a modulator for ATSC best buy has one they send there signals to evey tv via a modulated channel most of them use like 10.1 or 12.1

most of our homes already have the RG6 run to evey room in the house even if the modulator cost $5000 it would be cheaper than buying HDMI cables and running it all to every room in the hose and adding in boosters and wall reconstruction for half the house you would be talking about way more work, money, and potential problems

I too have been looking for somewhere to but what the retail stores have I have several people with VERY large houses and there looking at puting in over 500 feet of cable to get it to every TV more and more of my customers are wanting centeraly located HD recievers and/or pumping the signal to 2-3 HD tv's this gets realy pricy and dificult to do even with cat5e converters your paying alot for the convertion at each end and the spliters are not cheap ether pluse you have more stuff that might break or need ajustments

giving us a simple modulator that you can set to a ATSC channel would be easyer we already have NTSC modulator for standard TV

and we know they can do it dishnetwork's old 5000 model back in the year 2000 had one as an add on so we know they can do it NTSC is modulated all over the place whats the difference changing over to ATSC ??just a HD picture instead of a standard picture

if anyone knows where to get one or at least where to price one out let me know

As previously mentioned, ATSC has no form of copy protection. The MPAA and other organizations that own digital content will not permit a consumer device that takes their content and sends it out "in the clear". Obviously, ATSC modulators exist as TV stations have been using them for years. However, the price point will be such that they will always be too expensive for the average person to think about owning one.

The ATSC modulator that Dish sold as part of the 5000 receiver was a special product that would have limited use other than taking a Dish MPEG-2 transport stream and repackaging it to go over channel 3 or 4.

In-house distribution of HD video is best done via the home LAN. If you can afford multiple HD sources, you should be able to justify putting 1000BaseT in every room...

Since satellite HD is mpeg4 now the simple dish 5000 modulator couldn't work anymore anyway.

There is a VGA to QAM modulator out though, its $500

Understanding the problems with protecting digital content, would there be an issue with someone making an ATSC Modulator (preferably frequency agile) that accepted Component Video, and either two channels of analog audio, or SPDIF digital audio?

There are indeed numerous ways to distribute hi-def throughout the home, but placing multiple sources on different ATSC digital channels would be very nice, even if you were limited to Component Video and not HDMI.

Just wondering...
