Default New standard for AV cable

For those of you finishing your basements, in addition to running HDMI you may want to run some CAT5 for your AV. HDMI may be dead by the end of next year.

Ugh.

While I am no fan of HDMI, I need to point out that there is waaay too much of an investment in HDMI right now to kill it off so quick.

TVs, AV Receivers, cable/sat boxes (which have a PLC of 5 YEARS), DVD players, and more all now have HDMI on them by default. Making a sudden sweeping change will be very difficult. Especially with cable/sat boxes which are always several years behind the curve when it comes to connection standards.


Also the math doesn't exactly add up. That article states HD video over 100Mbit cable.

Uncompressed HDMI 1.3 supports up to 10.2 GIGabits. So there is going to be a wicked amount of compression going on in order to fit that 100Mbit.


Now I am not saying don't place network cables where your TV jacks are. I've been pushing that for 3 years now and that is the minimum standard I recommend for all new house rough-ins. I can almost say everyone under the age of 40 has tried to get their computer hooked up to their big TV somehow.

Anybody working in standardizing fiber optics for home A/V application? It's the next logical step.

I've spec'ed fibre for some based on Crestrons DM distribution system. HDMI+ethernet+USB+control all in one.

As for anyone taking it, not yet.

They also just released a copper solution, which is easier to pull and terminate.

Thanks Greg. I guess fiber optics is too cost prohibitive at this time. It's too bad though as all the electromagnetic interference challenges associated with other media (e.g. copper cabling) are non existent in glass / photonic media.

Fibre also has advantages with distance. So there are many benefits, but it does cost more and can be more difficult to work with in comparission.

First thing I noticed too when I read the article about it. It's too early to know where that is going to lead.

That is one chance, the other is the new HDMI spec 1.4, that does away with Cat 5 and allows bi-directional network connection in the same hdmi cable. This is already available and starting to show up in the hardware.

I did our basement with spec 1.4 in wall rated cables. The reality is what ever you choose will eventually be out of date, but I suspect HDMI is going to be around for much longer than say Composite or S-video did. There is simply little to no gain to be had as far as picture and sound quality. Until 1920p TV's are available there is no need for a new connection method.
