Sky HD
April 15, 2010
You wouldn’t believe the amount of calls we do to people who have a Sky HD box but are not watching HD channels in HD.
To view HD broadcasts in HD quality you need 3 things; firstly a HD TV. Secondly, some form of HD broadcast. The HD broadcast can come in the form of a Sky HD box, a Free to Air HD box or a BlueRay player. ( Some computers and media streams also transmit in HD. ) The third item needed is where most people running problems, you need a cable connection capable of carrying a HD signal, typically a HDMI lead.
We see a large amount of customers who have scart and HDMI connections between their HD box and TV and are viewing HD programming through their scart connection. Since scart connections are not capable of carrying HD signals these people are looking at HD broadcasts in standard definition.
All Sky boxes and almost all DVDs and VCRs have a feature that activates the AV channel on the TV when switched on. So what is happening with the Sky HD box is that as you turn it on the box sends a message to the TV via the scart connection that there is signal on this connection and the TV turns on this channel. The TV will bypass the HDMI connection in this case and show the AV, standard definition channel. There is no need to use a scart cable to connect a HD box to a TV as the HDMI cable will carry the standard signal as well as the HD signal.
The BBC technology website wrote a great article lately on the same subject, which can be found here.
