Bandwidth. No TV anywhere globally is broadcast in 1080p and that is not likely to change for quite some years.

@kiwijunglist Please don't suggest to TV producers that they should drop to 25fps!! it is bad enough that film is still stuck with 25fps hangover from many years past without introducing it to TV... ewwww!

Check your picture setup, most tv's are factory set to 100% contrast and 50% brightness, turn off dynamic contrast and lower contrast to around 65% and bring up the brightness to suit, i install these tv's some do look very average but in all cases i advise my clients to follow these steps

Yeah 24/25/30 fps for movies is crazy!

but i wonder what would look better 1080i @ 50fps or 1080p @ 25 fps, not really relevant. I find that 1080i TV3 looks better than 720p TV1+2, however if i didn't have a full HD and really good vector adapter deinterlacing on my HTPC, then I would say 720p would look better. The nice thing about 720p is that you don't need as beefy hardware as you do with 1080i.

If you compare Freeview HD to analogue there is a big difference. From you post you are comparing it to Freeview sat so are comparing digital to digital. Not so much of a difference there, I would think. Also did your sat box upscale the input? If so even less of a difference. Personally when you get a good true HD program playing I think it is a really good picture. Even the upscaled SD is pretty good.

no stb will upscale. satellite freeview is low def and allways will be, there are no plans for fv to hd on sat.
if your sat reception appears the same as hd-t then a big issue is apparent, sat is ld, fv -t is hd 720p, huge dif
best from sat is component input(RGB) this is the highest res from low def, low def rf can be better than comosite and equal to component if controled correctly

Topfield TF5050CI satellite receiver upscales to 720p and 1080i and I'm sure I have seen others around. Also component is capable of carrying 720p and 1080i signals although as a analogue signal not digital.

Component is capped at 720i, up scale is only capable if the compresion of data is available. no compresion is available on fv sat

Component can carry 720p and 1080i. Have a look at the Oppo blu-ray players. It could do 1080p but it is disabled due to copy protection. 720p and 1080i are going to be disabled on blu-ray players from the end of this year.

Freeview certified boxes are limited to 576 output over component. Uncertified boxes can and do pass through the 720p and 1080i signals via component. Check out the Draco's for this.

As for scaling many dvd and blu-ray players upscale dvd's to 720p, 1080i or 1080p.

@geoffp as stated by wallop component is capable of anything up to 1080p. Read http://en.wikipedia.org/wiki/Component_video to find out more.

IMHO Last time I looked at DVB-S there was some serious compression going on. If you can't see the difference between DVB-S and DVB-T even when not watching a HD program on a HD TV then something is either wrong with your setup or your eyes. No up-scaling could not fix the issues I saw.

720p and 1080i are going to be disabled on blu-ray players from the end of this year.

I thought the disablement was going to be in the form of an ICT flag inside the Blu-ray discs. Are they going to also disable HD over component for non ICT flagged discs on new players too? And also disable 1080i over HDMI/HDCP?

From what I read the blu-ray license for new players will mean only sd can be output over component.

I was stating transmittion specs, yes sd will only be the thing on sat, hd will increase as and when the fiber optics are sorted out, if you are seeing the same result from FV sat on FV hd then take the tv back and get a LG PK750, by far the best i have seen and sold

I have Freeview HD and I see no difference between that and normal TV. It is built into my TV which is also full HD.

How big is the TV and how far away are you sitting from it?

http://carltonbale.com/1080p-does-matter

As you can see from the chart above if you are sitting far enough away you will not see any difference. The person watching also plays a part. For instance myself and my son can clearly see the difference in HD material verses SD but my wife and daughter only see a difference when it is a very good quality blu ray and then not significant.
