OK, this does go against every bit of evidence I've seen, coupled with my own experiences of video transmission..but I don't mind you explaining how this is possible.. just to be clear, "how can you transmit 50frames per second over 576i"ernysmuntz said:It doesn't work like that mate,576i can be 50 frames per second?
I was thinking about the phosphor persistance of 'normal' SD TVs (50Hz with no processing), AFAIK to reduce flicker, the phosphor persistance is quite high, acting as a low pass filter, and thus filtering anything above about 30Hz.. (As I keep stating, I can understand the ability to see 60fps on a display capable of displaying it)The human eye isn't robotic, it there is no actual limit on what it can detect, I'm sure most people can quite easily tell the diference between 60 and 100 frames per second even.
Assume I am not an idiot, and have just enough intellect to understand most scientific principles etc, and take the time to explain it to me, I don't mind if I am wrong, and I am genuinely interested on this matter, as it crops up everynow and again and I have some knowledge of video transmissions, but an no expert.Edit : Just read your second paragraph, you can't reason with an idiot, I'm not saying you are an idiot, but to explain to someone why they are wrong when they have no idea on the true facts of the matter would take much longer than im prepared to type for.
Ah, OK, I think you are alluding to an answer to the 50fps over 576i.. I had considered that you could transmit your 50 fields in this manner, i.e. Field 1 = Frame 1 odd lines, Field 2 = Frame 2 even lines, Field 3 = Frame 3 odd lines] rather then the conventional interlaced method, but surely this has some negative effect, i.e. massive temporal noise similar to single DLP devices, or a further reduction in veritcal resolution?Edit 2 : Oh dear I just read the rest....I don't know how to say this without offending you, I'd do some more research every single point you have made has no merit whatsoever, interlaced material can actually give a higher frame rate than progressive, 2 fields combined into 1 "frame" can give the impression of 50 frames per second...oh it would take too long.....![]()
Plus, with modern TV's (Plasma's/LCD's) and their processing, they do a great deal of inter-frame/temporal processing on interlaced material to 'smooth' it out.. can this explain to some degree why some people are happy with a 30fps games?
I've tried doing plenty googling, but every reference to interlacing and video games seems to just repeat the old 25 full frames split into odd/even lines transmitted in 50 fields.. I did find this, some info but I am not overly sure if this helps the argument.
