True of False?	Can't Post

Any modern television and DVD player can play 60i footage. True or False?

I think this is true... I don't know the technical reasons. Any takers?

Thanks,
Cheers!

True.

"60i" is another way of saying "standard NTSC video". If any modern (NTSC) television or DVD player can't handle that, very few people would buy it. Wink

Wait... so it's 60 fps/interlaced?
Isn't that a high frame rate for broadcast television? or does broadcast television shows actually display a lower frame rate?

29.97 frame per second X 2 fields (upper and lower) =60i

OK... that makes sense. (I feel like an idiot right now, by the way. Crazy

)
So here's the question I really wanted to ask:

Remember when Gran Turismo 3 had that special 60fps mode where you could only race one vehicle (too many polygons for all vehicles)? That was displaying true 60 frames/second. So what's the deal with that?

Can a televisions raster even go that fast?
(maybe it was a progressive scan mode of some kind... I dunno.) Do you?

Thanks

That sounds like a video game refresh rate which would be more applicable to playback on a computer than on a TV set. Most traditional TVs by definition display 60 alternating fields per second creating 30 complete frames, and that's it. Modern digital TVs might be capable of displaying higher frame rates like a computer monitor, but standard HDTV formats (ATSC) are mostly either 60i or 30p.
