HDMI Matrix Switcher vs. HDMI splitter to each room

post #1 of 4
Thread Starter 
Hi everyone -- long time listener, first time caller (reader/writer...you get it)

Here's the situation. I'm redoing the house, and inside a fairly spacious storage closet (7'x8') I'm going to put a rack with all of my gear. No need to get into specifics yet, but know it's all HD...tivo box, cable boxes, bluray, gaming, etc. Within 25-50 feet of this area, will be a total of four Panasonic plasma displays. Each display will have a universal remote (ie Logitech 890), most likely RF, that will reside in the same room as the display.

I'd LIKE to use a 4x4 HDMI matrix switcher with CAT 6 runs...but am completely convinced now from the posts (and lack of posts) that this is a nightmare. I've got a dear friend who is an engineer in broadcast TV that suggested I do this:

Split the HDMI from the source (bluray, cable boxes) four ways each...and send individual HDMI cables to each montior...switching the monitor inputs to get each different source.

As far as controlling the devices, I'd put the RF reciever on the back of the monitor, and extend the infra-red cords all the way to the video source.

So -- this way involves A LOT OF CABLES -- but assuming the split is good...sounds like an interesting way to get around the matrix switcher issues.

Any thoughts? Any suggestions?

Nope - you're essentially building an HDMI matrix switcher... The HDMI issues will still be there. Once you try to "split" the HDMI signal to more than one TV, is where the complexity comes in. Because HDMI is talking to the display, the source device will make decisions (good, bad, or random ) based on what it finds at the other end of the cable. It's when the capabilities of the display devices are different from each other that things get interesting.

Now, if you're connecting 4 similar / identical / same vintage Panasonic plasmas to an HDMI matrix, you may not have any issues at all. But if there's a receiver involved, you may still have difficulty in getting the "advanced audio codecs" from the BD player, etc.

Read the reviews of the matrix devices to make a selection - I'm personally using a component video matrix instead of HDMI to avoid the issue altogether for now, and just put a 'local' BD player in the one room where 1080p and DTS-MA / DD+ is important...

Be aware that starting at the end of this year, you'll need a local blu-ray player where 480p is important. Google "AACS Analog Sunset" for the details.

Also, I expect cable and sattelite provides to follow suit not long after.

*IF* they go through with that, it's only for AACS-licensed (Blu ray) players manufactured after the end of 2010 (and not even the 100% because existing models can continue to be produced), and it would only affect existing users if a studio starts turning on the Image Constraint Token on new titles. Which I don't think they'll do, IMO, since this whole concept doesn't prevent piracy at the *real* sources, and will instead piss off their actual paying customers... CEA should be pushing back, too, for the hundreds-of-thousands of citizens that bought HDTV sets without HDMI/HDCP capabilities. And add the FCC to the list of folks that should stand up for the consumer if the cable/sat guys start limiting HD content.

But yes, its good for everyone to be aware of this possibility/eventuality/certainty/load-o-crap. And I wasn't recommending that he a component matrix over an HDMI, but that is an option. I'll probably expand my component matrix this year, and will certainly have any BD players I expect to need for a while purchased late this year...
