A client has moved to a place with no wiring to his eventual master bedroom TV location. There is, however, a component head end in an anteroom with a wired TV location. There's also a TV location at the ceiling of the adjacent master bath.

What I'm thinking of is to put the program output (mostly DirecTV, maybe also a BD Player) into a 1x2 HDMI splitter in the equipment cabinet. One output goes to the anteroom, one output goes to the bathroom TV.

At the anteroom TV, we put another 1x2 HDMI splitter. One output goes to the anteroom TV, one goes to the master bedroom TV.

Construction of the rooms and limited attic space make this a better option than a 1x3 HDMI splitter at the equipment cabinet.

Have you got any observations about the way to do this, or things to watch out for?

Thanks for the help.

Not only is that solution not that expensive, you only have to pull a single coax instead of an HDMI cable (which can get easy damaged), do not have to deal with a frankenstein of HDMI splitters (regular coax splitters), and you can add transmitters as you add sources to allow that bluray or streaming box to be added.

For a moment I thought my overseas client could make use of the Metra system. He built a HUGE place, with 17 racks of video equipment in the penthouse. These are filled with satellite receivers, each set to a channel. Their outputs are modulated to VHF and UHF frequencies and distributed throughout the house via fiber and cable. Each TV has a choice of satellite channels... in standard definition.

There had been a two-year hiatus in construction of the villa and the in-house satellite distribution was already hopelessly old when first fired up.

Today, the Metra system could use that distribution system to get 1080P out to all locations, but here's the hangup: whereas today there's just a TV at each location, implementing the Metra system means putting an M3B-RX at each location and somehow choosing channels in a system as simply as it would be to use a TV remote.

Hey, Brent, do you have any remotes that include M3B codes at TV codes? Are the M3B codes available to put into a one-for-all remote?

For that one, you need a commercial grade HD modulator. Like used in hotels and hospitals.

One of my clients is using a single channel version of the one you're talking about. Come to think of it, the price of that is well within this client's budget.

PVI is who you want to look at Ernie.
They have a lot of different modulators to choose from in every type of configuration and standard in the world - including IPTV streaming.
Large installations they have the new mini-blade rack units, and a new 1U rack unit that can do 24 HD channels.
5 year warranty. And pricing that is very competitive as well.

I use to get dealer cost with them. But for some reason they will not give me dealer pricing anymore. I'm not sure if it is because I need to do a certain volume with them or if they just don't do dealer pricing anymore. I have not been able to talk to anyone there when I've tried to communicate. But then I have bad luck with that kind of thing.

The guy I refer to in Post 6 has a PVI modulator that I installed.

Brad, ut's not you. My first two or three communications with PVI were easy and friendly. After that, several days went by with neither call-back nor email response, as though they had dropped off the earth. The eventual responses had enough info to figure things out, but were not very good from a technical point of view.

I've realized another difficulty for me with the Metra approach: there's about 500 msec of latency with the M3B, so if I take the audio directly from the source, then feed the video out to the TV, lipsync will be very poor. Worse, my situation has a signal going to one TV, then to another, so there are multiple locations where latency might happen and even add up.

Yup, PVI looks like the solution here. That's amusing since the client is minimizing the number of DirecTV boxes he pays for by having one run throughout the house via a PVI modulator. It hadn't occurred to me that another modulator would offer the simplest solution here, but it sure looks like that's the answer!

You didn't say anything about needing to break out the audio. We can't help without all the info

Yes, the audio breakout is a crucial piece of information that was not shared.
That rules the Metra piece out for this situation.
The PVI modulators have a feature to reduce encode time, there for reducing lipsync issues. But it is not perfect and there can still be slight sync issues sometimes.

If perfectly synced audio is required, then a much more expensive solution HAS to be used. You could use JAP with the audio breakout, it allows you to time delay the audio so that it is perfectly in-sync. Or you could use an HDMI matrix with HDBaseT and audio breakout, like Zektor has.

I don't need audio breakout. That's very odd, but true. Thanks for mentioning it.

The goal is to have a way to get this particular programming into the antenna system, basically as a means of reducing the number of boxes the client needs to rent. They want DirecTV in many rooms but hardly ever need more than two on at a time. As it is they have a Genie in the master bedroom, an RF client in the kitchen (where major surgery is required to get any signal cables into the room), and another client at the OTA system location. The OTA signal is so good they can watch it on a 50" TV.

Then the audio delay won't be a problem. I think you are thinking about it wrong.

Follow that link. Then consider that I am dealing with only one program. Thanks, anyway.
