I have an Hitachi 60V500 HDTV with two antenna inputs (A & B). I would like to install a CM 4228 and have the signal go through a HD receiver and out to my antenna 'B' input.
Would anyone know what type of HD receiver I would need to get this to work.

Any suggestions/advice on this would be greatly appreciated.

Thanks.

What is it you think this will accomplish?

After looking at the Hitachi site:

[Link: hitachi.us]

This is what I think you have...

The product has dual 181 channel NTSC tuners. The NTSC tuners will not receive HD. So even if you bought a HD tuner that would modulate the signal to NTSC, you then wouldn't have HD resolution, as NTSC will not support either 720p or 1080i.

You can choose any HD receiver that has either a Component Video or DVI output, as the Hitachi you have offers both as inputs.

If you are using the remote that came with the set, you might want to Consider a Hitachi receiver. I assume the remote from your set would operate the receiver directly, making your setup slightly simpler. If you are using a programmable remote, Your choice of receiver is limited only by the inputs your TV offers. Again, be sure to look for DVI or Component Video outputs.

If you have other devices connected to the set, be sure to check which connections are being used. If the DVI is being used by some other device, you would be better off choosing a tuner with component video outputs.

Automan1,
You'll have to excuse me here. I know I want to convert the off-air signal to HD but as you can see I don't have clue as to how to do it. The post after yours suggest purchasing a HD Hitachi receiver and using DVI or component cables which sounds like a step in the right direction.

BCF1963,

You've given me some great ideas. It's awesome people like yourself why I love this site.

Thank you very much for your suggestions.

Yeah, like bcf and automan said.

The RF output of any device will not be HD. Think about it: that RF output comes from a tiny little TV station inside the unit. Thirty years of repetition have gotten the manufacturing cost of the Channel 3/4 modulator down to about two bucks American. The price of an HD modulator would far exceed the cost of the rest of your system.

That RF output is a convenience in case you want to send a facsimile of the HD channel to other places, not a way to watch HD.


By the way, in case you think that the current crop of modulators, which range from the channel 3 type for $20 to the variable channel ones for one to two hundred dollars, are in any way a ripoff -- I have designed several small circuits for doing things with audio or with control voltage, and

once the circuit is designed, there is the major pain in the ass of designing and building a power supply dedicated to it, or buying a wall wart, which is why so many products use wall warts, and

buying and customizing some freakin kind of box to put the thing into, and making screw holes in just the right place so it will actually go together and close. Not to mention putting the jacks through the surface. If someone decides to build millions of units, then a plastic case is in order, because that way, the several thousand dollars of cost for a custom mold can be amortized.

The variable channel ones have the added costs of digital frequency switching, and some have stereo sound modulation. Neither is cheap.
