America 720p ours 1080p, I cant see the diffence what is it for.
its all about epenis
american tv standards dont support 1080p yet, but their 720p has a higher frame rate than anything we show over here.
bluray only support 1080p @ 24 FPS, which is ideal for us, but not american TV standard that support 30 FPS, which is possible with 720p
1080p can now go upto 60 fps, but the standard has not quite been adopted yet.
TVs can be provided with electronics to interpolate frames, or it could be done before transmission, as the American system has done in the past. Frame rate is no excuse. Its cost and bandwidth, if they went to 1080 it would require a lot more data to be transmitted. Older equipment would have to be replaced before the end of its economic service life.
Reality is much simpler, unless you have a really huge TV the difference between upscaled 720 and real 1080 is minimal at best. This is also why so few Blueray units are being shifted.

no serious. Its because we use PAL & America use NTSC - its nothing to do with bandwidth or transmission as blu ray comes on a disc!
American TV standard is 29. somthing frames, 1080 did not do that high when american adopted its standard for HD
Our PAL is 24 odd frames, which is easily do-able by 1080.
NTSC is specifically for 525 lines and is the US old standard for VGA, it has no bearing on 720i, 720p, 1080i or 1080p standards which are separate and covered in the us by the ATSC standard. This certainly does cover progressive 1080 at 30FPS but as low as 23.98FPS. NSTC transmission was switched off permanently on June 12, 2009.

The apparent difference between 525 lines and VGA is simply that some lines are not used.

Are you saying youve found a Blu-ray that is only 720p?
If so, then that is messed up as all blu-ray disks Ive got, whether US or Euro, are 1080p or the odd one that is 1080i. Ive not seen one that is only 720p though.
Maybe it says it supports 720p - Would need wording like that for the uneducated peeps whod think it wouldnt work with their 720p TV.
As far as I know all blueray units are pretty much identical in specification, they normally display 1080 if that is available, if not, or there is another issue like lack of HDMI, they drop to 720.
