Sky HDTV Set Top Box Rear Connectors

Sky HDTV Set Top Box Rear Connectors
Having looked at the information on the Sky website, we thought it only right that we highlight what connectors are available on the new SKy HDTV set top boxes to help those with older displays make sure they are compatible.
One of the main re-assurances Sky made to those potential new Sky HDTV customers with older display technologies was the inclusion of analogue outputs for HDTV broacasts. Unlike the existing generation of Sky Plus set top boxes, the new Sky HDTV set top boxes will feature component video output which gives superior video output quality compared to the standard scart RGB composite sync which can cause problems such as visibile scan lines when connecting to large lcd and plasma displays even when used with special TTL composite sync cables such as the Keene Electronics 'Syncblaster' range.
Although not confirmed yet hopefully Sky HDTV broadcasts in 720p will be output in pure progressive through the component outputs. 1080i broadcasts will of course be interlaced.
So what outputs do you get on the Sky HDTV boxes?
1. 2 LNB satellite signal inputs

As on existing the Sky Plus boxes, the Sky HDTV will accept two LNB signals meaning you can watch/record two separate channels.
2. RF UHF Modulated Inputs/Outputs

The Sky HDTV boxes also have the standard TV ariel inputs/outputs, although anyone contemplating using these as the output/input signals for HDTV broadcasts really does want taking outside and hitting with a big stick.
3. Optical Digital Output

Optical Digital Output via a toslink digital cable so that 2 channel and more importantly 5.1 surround sound can be sent to a Dolby Digital decoder.
4. Component Video Output

Component Video Output or Y, Pb, Pr, or Y, Cb, Cr gives the best possible analogue video ouput.
5. Analogue Audio Output

2 Channel analogue audio output via left and right RCA phono sockets
6. SVHS Video Output

SVHS or sometimes known as Y/C gives separate luminance (Y) and chrominance (C). The chrominance signal outputs the color information and the luminance signal outputs black and white or brightness information.
7. SCART Sockets

As with all existing Sky set top boxes, the new Sky HDTV set top boxes output RGBs & composite video signals on the TV ouput SCART socket, and allow RGB input & composite input/output on the video scart socket.

This will be the preferred output connector for those people with HDMI compliant displays. It provides a digital and video output allowing for potentially the clearest interference connection between the Sky HD set top box and HDTV readt television. It also has certain security features that copy protect the digital outputted signal.
9. Other

There are also a number of other connectors which allow for further enhancement and integration with PCs and media devices although at the moment details are sketchy. Anyway as well as the 2 way mains connector and the service testing RS232, the new Sky HDTV boxes will come complete with a USB port, ethernet port and a SATA input which could be interesting but as no documentation exists for their use it is hard to make comment.

I am about to apgrade to an HD box from the standard SKY+ box, but have one worry relating to HD channels and recorded HD content.

I am currently using the second RF output to drive a small portable TV in a second room. Does the SKY HD box 'downscale' the HD content so I can watch it on my non-HD portable?

Many thanks for any help.

I think you only get HD content via the HDMI from a Sky HD Box. Any RF output is converted to analogue UHF signal

Excellent! So I should have no problems watching recorded HD content on my SD TV :) Of course it would be better to watch it on the 'big TV', but sometimes it's nice just to sit in bed and watch TV :)

Thanks for the help.

Can I employ an HDMI router to supply alternative TV's with the HDMI signal ?

All new Sky HD boxes no longer have component outputs but do have an additional co-ax digital output.

I have sky+ hd with an optical output. If I connect this output to the optical connection on my hdtv would it be beneficial to sound and picture?

How can I come off my dish to a second tv in the bed room,thanks to all.

If you take a cable from your LNB on the dish you will need a decoder to put on it and possibly(if you want to watch sky) a sky card for it - this would be a multiroom setup - costs you £10 per month approx. To connect from the SKY HD+ box you will need a (long) cable to connect one of the outputs detailed above to one of the suitable inputs on yor bedroom tv. The exact cable and cost will depend on what options you have. Simplest would be a coax for RF UHF - but don't expect an HD quality picture.

houses wired for "old" terrestial tv are sometimes hard wired to a number of rooms for tv - I disconnected roof aerial (in attic) and just connected rf from sky box straight into wall socket in lounge - put amp in attci nest to distrbution box and now have sky in all rooms - plus sender to change channels when watching in bed - better picture tha sending signal through sender unit - hope this helps

Does the new non PVR HD skybox have audio outputs for connection to surround sounds systems??

I'm not too techy..Sky have sent me a new free box to replace the Thompson box.
The Thompson has ports for terrestrial input and 'outs' for going to a room with magic eye and another to attic splitter box and then to 2 more tv's
New box has none of these so what are my options to replicate the same .. Says:

There are just a small handful suppliers of cable television in the UK, as most
consumers prefer to make use of satellite or IPTV (streaming
by means of the Google).
