1280x720P@60FPS Using BEV: Wasted Upsampling For Movies?

Most movies record at 24fps or 30fps, do they not? So why is BEV sending out all movies at 1280x720@60fps? Are they upsampling the frame rate for no reason?

I know hockey/live sports could use the extra frame rate, but almost every other channel probably doesn't. In general, would this not be a waste of bandwidth for the provider?
 
In order to send out the signals at 24fps, the receiving equipment would need to do the conversion to 60fps. The receiving equipment would also need to be able to handle flags or detect signal changes when frame rates change in order to switch conversion protocols on the fly. This is probably better handled by the broadcaster. It would increase costs for receivers and make them less reliable.
 
I'm not sure they do.
When playing back recorded (from BEV) HD movies using NVidia post processor it reports 24fps.
That would imply that the stream is sent in 24fps and flagged for 60fps presentation.
The majority of modern HDTVs don't support refresh rates at a multiple of 24 (just CRTs and some newer JVCs, I think)
and non-movie footage is 60fps natively. Also, I don't think satellite receivers can handle 24fps natively.
All this makes 60fps the common denominator.

BTW, some of the movie channels are 1080/60i.

Diogen.
 
Ah ok thanks. I have never seen any of the movie channels at 1080/60i. Nimiq 2 seems to show PPV @ 1280x720@60fps (as far as I can tell, and as of March 2007). Thanks for the responses though.

It just means I would need to find an intelligent frame decimator to accurately cut out the duplicate frames to bring it back down to its native frame rate (argh).
 
The reason is it's defined by the ATSC as 1 of the valid HD formats and must be compliant to work.

The "P" in 720p indicates 60fps.
 
"The "P" in 720p indicates 60fps."

So progressive scan = 60 Frames Per Second??
That's news to me.
 
Dude, that is just so wrong I had to respond. And the "i" in 1080i stands for...?
 
Note that neither 1080i nor 720P specify a framerate and it can vary - here are the 18 allowable ATSC formats. Note the framerates allowed.

(I'm posting it only for the chart as a summary of the ATSC formats since some of the information in the articles is old or incorrect.)

I suppose I could have searched for another ATSC chart, but I had this one handy.
