Pel is just another name for pixel: https://en.wikipedia.org/wiki/Pixel
I assume that's not what you mean, do you?
Do you really read wikipedia?
What I mean is this:
Pel - a displayed picture element.
Pixel - an optical data sample.

No. In the context of video compression (such as MPEG), a frame is a
unit that is part of a video
What if there was no such thing as frames? How would you get pels into the TV?
To be clear, the TV doesn't have frames, either.
and that describes what to do in order
to arrive at the desired screen contents associated with a certain
time stamp. A frame does *not* have to be an individual picture.
It may well consist of just a single macroblock (in H.264 terms), or
even be completely empty. In the case of variable frame rate, an
empty frame may be omitted altogether, saving a few bytes of header
data.
I almost suspect we both mean the same thing, but you refuse to call
it a frame. :-)
Nope. Not frames. Pels.
Are we having fun?
