Karl Dallas: No, it's a is subscription channel. You have to pay Sky to watch it.

chris: Yes indeed, the transmitter is a low-power relay (10kW analogue, 100W/200W digital) compared with Crystal Palace high power output (1000kW analogue, 10kW/20kW digital).

Des Collier: Strange that, of course, ITV was supposed to get better when it merged into a single company, but if you look at the viewing figures the decline is very obvious.
The BBC has declined a little, but ITV has lost many viewers.

Michelle: Well, you would have channels called "BBC One HD", "BBC HD", "ITV1 HD", "Channel 4 HD", "S4C HD" and so on.

bernard hunt: The original is on 35mm film.
35mm film frames are 22x16 mm (1:1.375), but using various lens can be used for different aspect ratios for television and cinema.
The BBC will be producing a 16:9 HD broadcast as far as I understand it, and this could be done in two ways.
If the original film was used "full frame" (without an anamorphic transformation) then a 16:9 (ie, vertical) cut-out will be used.
If the original was in a "cinematic projection" (which is more conventionally) then the 16:9 will more-or-less match the original.
I'm going to guess that it is the latter, as I recall that Civilization was shown in the US in cinemas.

Les Nicol: No, that's not correct. That is not setting the picture format, that is setting the viewing format.
The picture format (either 4:3 or 16:9, sometimes 14:9) is the anamorphic correction applied to the picture, which in effect is the correct description of the pixel shape.
HD pixels are generally 1:1, matching what you see on computer monitors, but on UK televison it has bee 1:1.13, 1:1.21, 1:1.89, 1:1.42, 1:1.06 - see A comparison of TV, HDTV and computer monitors | ukfree.tv - independent free digital TV advice .

Martin: I'm pleased to hear that.
The commercial DAB operators are not part of the BBC schedule, so I can't say when you will be able to receive those services.
