Guys,
Not sure this is the right place, but here goes:

I'm on Sandy Heath TV transmitter, which has "gone digital" from today, I've had to re-tune my TV & associated boxes.
I've got an HD set-top box connected to my HD ready TV using an HDMI cable.
So I'm expecting to receive BBC 1, BBC2, ITV & ch4 on HD.

How do I tell if I'm receiving these in HD or SD ?

Thanks

John
 
The HD channels are separate to the SD channels, your guide should list the HD channels.
 
If you cant tell the difference perhaps eyesight and a hearing test might be a good idea:nenau

it should be obvious from about 10 ft away or closer. less obvious as you move further from the set.

Its even more obvious than that, the channel title has HD in it, as in BBC1 HD. I did a check for you and there are no freeview HD channels until the 15th of April but they wont be anything like the quality you get via satellite.

Why not? I have a Freeview HD box and get 4 HD channels and the quality to me seems the same as Bluray. Surely an HD Digital programme would be the same quality whether it was via an Aerial or Satellite.
 
HD as a standard is just a screed resolution which for 720 is 1280x720. It says nothing about the compression ratio attached to the picture. For example you could have a ripped copy of a DVD with same resolution which is still SD but if someone compresses it down too much it wont look as good. Youtube HD is still HD but the videos look nothing like as good as a Blu-ray. Likewise you can rip a blu-ray and keep the resolution but compress it and it wont look as good. In fact not all Blu-ray movies are of the same quality. Its all about size, the higher the quality the bigger the size. Satellite has much more bandwidth than terrestrial Digital so the video isn't compressed as much hence it looks better. Its also why you will never get all the HD channels that you do through satellite, there just isn't the bandwidth. Better than normal Digital it definitely is but it still isn't as good as Blu-ray or Satellite.

Make sense?

Plus which, Blu-Ray is 1080p; HD TV is 1080i.
