I've searched for this and not found just what I'm looking for.

I'm putting a TV on my deck. I don't want to put another DVR outside. The DVR in my library is literally going to be only 10 feet or so through a glass door (with another TV).

What I want to do is split the signal that comes back out of the DVR, running it back into the wall and out to through the attic to the TV on the deck that will be hanging up out of the weather. I've tried taking the DVR remote out on the deck and I can change channels just fine. Lots of glass!!!

Is this possible? If so what kind of splitter do I need? Anything else that I should worry about?

Is there any "Outputs" on the back of your DVR ? (you didn't say which one you had, so I could not look at it)
If you have a Component Out that would work great, or any of the other options available, but the Component Out would give you the best signal.

You don't say which type of signal you're using: component video, DVI, or HDMI (I'm assuming you're not using S-Video or composite). In any case, there are distribution amps available for all types, you just have to buy the correct one.

If you're using DVI or HDMI, you have to be careful about the HDCP (copy protection) that is built in to the format, as splitting the signal may cause confusion or incompatibility that would prevent seeing the picture. Your safest bet is to use component video which won't be subject to that problem and should provide just as good a picture. If you're sold on HDMI/DVI, then you'll just have to try it and see if you can make it work. Many splitters do advertise HDCP compatibility.

Here are links to distribution amps (splitters) for the various signal types:

Component Video (one of many, many options): http://www.markertek.com/Product.asp?baseItem=HDDA%2D2&cat=ROUTERS&subcat=&prodClass=VIDEODA&mfg=&search=0&off=

HDMI: http://www.markertek.com/SearchProduct.asp?item=GEF-HDMI-142&off=0&sort=prod

DVI: http://www.markertek.com/Product.as...&subcat=&prodClass=VIDEODA&mfg=&search=0&off=

Obviously, because of the digital nature of HDMI and DVI, those splitters are quite a bit more expensive. Another reason to use component video. You can also get versions that split into many more outputs than just two, if you want to hook up 4 TVs, or 8, or whatever.

I would not recommend using a "home-grown" version of a splitter, where you just physically split the output using three wires (one in and two out) soldered or otherwise jerry-rigged together (I doubt you would succeed in making one of these for DVI or HDMI and it wouldn't work anyway, but it could be done for component). That could have a substantial negative impact on the picture quality.

Thanks for all your input guys. I'm probably going to have my 10-250 in this room to split off. The TV in the library is an Oliva 26" LCD. The one on the deck is a 32 inch standard def Sony. The Oliva of course will use the DVI output. I just want to get some type of signal to the Sony so I can sit on the deck and watch TV. Obviously that signal to the Sony doesn't have to be HD. Just about any old signal will do as long as it is watchable. I'll be out there when I'm grilling or in the hot tub mostly.

Just run component cables (red, yellow and white) to your deck from your receiver.

If you'll be using the HR10-250, keep in mind that HDMI and component video are not active at the same time. Realizing that the remote TV is just an analog set you're probably not planning on using component anyway. That leaves the composite/S-video outputs (the HR10-250 doesn't have RF out). You can run either of these directly (along with analog audio) but an easier solution is to run them into an RF modulator and then just run coax to the TV on your deck. This will work fine (I have a similar set-up) but you'll need to change the output resolution to 480i in order to get a video signal from the composite/S-video output.

Cyboko,
You just described "Composite, not Component"....

scotsmanron,
I would recommend using Component if possible (Red, Green,Blue) keep in mind ,if you use that, you will also need audio cables (Red/White)

Looks like I've got lots of options. The TV will go outside in a couple of weeks.

Jimbo, where can I get cables that are about 25-30 feet long? That will be the run up through the walls.

Also, your boys better not let me down in the BCS game!!! There will be no living with the cocky Gators in Florida if you all don't shellac them!!!
