future technology tv Complaints about the BBC's HD service rumble on  
I expect they'll announce Super HD shortly - after all the set makers have to be kept busy - and the whole sorry thing will repeat... They already have Ultra HD. http://news.bbc.co.uk/1/hi/technology/5335870.stm I would hope in the future we would get away from the strange to me at least 16x9 ratio Think this might have been done probably due to limitations of the CRT. I would like to see the cinema screen ratio used in the future. Yes I know the movie screens vary but is the normal w/s  2:1?   Going up to 2.5:1 for the epic _style_ films? I hate 2.25/2.35 ratio, at least for films to be shown on TV. My heart sinks everytime I put a DVD on or watch a movie on TV, and it's in letterbox format. Apart from the fact that none of my TV's zoom functions scale equally in X and Y (so distorting the picture), it means at least 100 lines of vertical SDTV resolution is wasted. Worse are the letterbox formats designed to fit into a 4:3 _frame_, which I calculate are only using 320 lines of vertical resolution (I remember trying to watch Grand Prix, originally in 70mm, in this format, on TCM, which does not believe in high bitrates either). Why can't the transmitted picture use the full SDTV height, then be stretched horizontally in the TV? Better still, transmit only the 16:9 central portion, to preserve horizontal resolution too.
