I am going to try to get Sky to run an HDMI cable from the box - through the wall, up the outside of the house wall - through the bedroom wall, across the bedroom floor to the TV (40 feet) - will that be OK - attenuation-wise ?
Also - I assume that the "non-HD" signal will be better than on the old (UHF) cable ?
What also concerns me about this mixed HD and NON-HD usage is that, presumably BBC1 HD is a different channel to NON-HD - So what happens if both TV's are being watched simultaneously ?

In which case there is no point in having HD on the set as you won't see any difference in picture quality.

I use a magic eye from my Sky+ HD box to the bedroom TV.
The HD channels are transmitted up the UHF link just like all the others. BBC1 HD is Sky Channel 143, BBC 1 is channel 101.
Sky won't be running any HDMI cables for you unless you can provide the cable and a bottomless tin of hobnobs.

and now the graph!

I have a Sky HD box in the bedroom and a magic eye cable run to a downstairs tv for changing channels etc but the TV picture is sent via an HDMI splitter / amplifier (£15) and a 10 metre cable (£6 ) so as to get HD pictures on the second TV.

Here's the HDMI spliiter I bought , you should be able to find long HDMI cables ( 15 metre ?) on Ebay for around £12- £15 too.

Get both the above and connect the first TV to the Sky HD box via scart , the HDMI from the Sky HD box to the splitter input , the long HDMI cable to the splitter output and onto your bedroom TV.

Don't worry about the HDMI over riding the scart as I've tried it and the both outputs work at the same time.

If you want to buy/run a 40 foot HDMI then you can
its plug & play

Does such an animal exist? I've never seen a HDMI cable even approaching that long.

That screen size is far too small to fully appreciate Any improvement in quality HD might bring.

I agree.

Wrong query, I meant to say say I haven't seen any HDMI that long in actual use.
Wouldn't there be significant degradation of signal over that kind of length?

Shouldn't be an issue, but you can always slip in a HDMI repeater/booster at the start of the run if the source HDMI is not up to the job.

The/one real issue with running long hdmi is the chance of damage.

Couple of questions for you Kurtis (or anyone else who knows the answers )

Chance of damage to what ? and what would you class as long enough to be liable to this damage ?

Also in a post above you said

can you please explain what is return IR and why I should be concerned about it ?

The connections are not designed to terminate long cable runs (most HDMI simply connects one component to another less than a metre away). There would be stress placed on the connections which might damage the lead itself or (more seriously) the sockets on the TV or decoder.

Obviously a reference to the late Gerry Anderson's "Thunderbirds" and International Rescue.
Return Infra Red is also a possibility, of course.;)

Thanks.

No worries then as my Sky box outputs to the splitter with a 1m cable, the splitter * is securely fixed onto a wall behind the equipment.

Splitter outputs to TV 1 via a 1m cable and TV 2 is 8m but the cables are secured at the TV side by the cable straps at the back of the TV so there's hardly any weight hanging on the TV HDMI socket.

Return IR is not a problem as I use a magic eye over Co ax.

* I think I'll do something at the splitter so the cables are also secured to the wall too.

Sorry, are you suggesting that HD channels from a SkyHD box can be transmitted via UHF ? If so, then surely that makes HDMI cables redundant ?

Or do you still need something at the 'remote' end to 'convert' the coax connection into HDMI ?

Indeed I am, the picture of course will be standard definition and mono sound at the remote set.
In the bedroom there are better things to do than counting pixels.:D
