Hi guys, hoping some of you techies might be able to help. I can't make sense of the Google answers!!

I had sky multi room installed the other day. But thanks to the configuration of my 1970's house, there's 2 plug sockets in the room, miles from the appliances!!

So I have my tv on the wall with a 10 meter Extension lead and HDMI Cable back to the sky box, t'other side of the room!!

However I get a message on the tv stating

I've tried all manner of combinations of different sky box, extension lead and hdmi lead and it's basically the 10m hdmi lead causing the problems.

So my questions are:

Can I bypass this somehow with a feature on the tv?

Are there leads available which are HDCP compatible?

Would a splitter in between the cable and box work?

Any advice gratefully received.

Cheers
Gaz
 
How old is the TV dude? From the message your getting it looks like your telly doesn't support the HDCP DRM protocol.
 
HDCP is basically copy protection - as far as i understand it, almost like an encrypted link between the Sky box and the TV.

Did you have it working at all on this tv previously??
 
I reckon it's about 8 years old. However it works with the supplied hdmi lead. It's just about 5 meters too short :rolleyes:

It's the Chinese 10 meter long jobby which won't work.
 
Based on my limited understanding, HDCP works a bit like SSL on network encryption. So the Sky box has a HDCP cert (I think they call them licences in this context) which it sends to the the TV with a request for that devices HDCP cert. The TV responds with it's HDCP cert and that authenticates the connection so the Sky box will then send the TV signal which you watch on the telly.

I'm guessing that your Sky box isn't receiving the HDCP cert back from the telly or the cert from the Sky box never makes it to the telly so it can respond. Therefore the Sky box thinks the telly isn't a HDCP compliant device and you get that error message.

God knows why the HDMI cable isn't sending or receiving the HDCP cert though...I wouldn't have thought the cable would block the certs, it's just a cable :) It sounds like your best options are either a better quality HDMI cable or a HDMI splitter between the TV and Sky box that ignores HDCP requests.
 
No JC not yet. It's trunked in all the way round the ******* room. That's the next step I think.
 
I vaguely recall having this issue, I think I corrected it by the order things were powered on. Try unplugging everything then tv on first then sky. Fingers crossed...
 
The tv is 8 years old Paul. The box is new. It works fine with the supplied lead but not the 10m one. That's clearly the problem just wasn't sure if there was a way round it

It's been about for ages! From what you have said, it's obviously the cable then :)

You could throw something like this in line..... http://www.ebay.co.uk/itm/111762912164 as i guess that because it splits the signal, it has to remove the HDCP, since the originating box wouldnt be able to HDCP to two destinations simultaneously...

Or the cheaper option would be to just buy a new cable...

If it works with the supplied hdmi cable but not with the Chinese hdmi cable the its definetly a cable problem.

If it was a cheap one cable it's probably not the best. A mate of mine had a similar problem and he had his cable built in before he tried it also, lesson there test before you install it in any sort of containment.

The bit thats confusing me is why are you sending the important bit (the tv signal) along a long cable?
Why not run a long extension lead for the power around the room to close to the TVs, put the sky box and tv into that socket for power and use the supplied hdmi cable between sky and tv

Then you won't have to point the controller behind you to change channel!!
 
Thanks guys. Believe me fellas if I could put the sky box next to the TV.............. Then it would be next to the TV. Unfortunately due to my shoe box bedroom I cannot fit the sky box next to it and I'm also bound by where the cable comes in to the room

So I will have to point the remote behind me when I want to change channels and route the cable round the room.

The lengths you go to to get rid of the missus upstairs hey
 
Okay okay.
Appreciate the advice
But for the last time

I CANT PUT THE ****ING SKY BOX NEXT TO THE TV. IT WILL NOT FIT.

:rofl::thumbs:

I do what you're doing with my lounge TV Gaz - all the Sky **** is in my hifi cabinet across the other side of the room, with a long HDMI cable routed under the floor. It works fine, so think you've probably just been unlucky and got a dodgy cable.
 
i'm with you Sarge, i remember the days at uni when our aeriel was a coathanger and there were 4 channels of crap. now there's 400
