1080 720 visual reference

[poppj]

Hello all. This is my first post. Ive done some research on the differences between 720i/p and 1080i/p. I want to make a good visual reference because there are so many people that want to know the difference and it can be hard to explain.

Ive created the following attachment and I wanted to know opinions and to see if ive done this right. I created it in photoshop... the 1080 lines are created using 2 pixels and the 720 lines are created using 3 pixels (so 720 pixels are 1.5 times the size of 1080). This illustration would be visual during movement onscreen because as i understand, there is no difference between interlaced vs progressive on a still image.

I was hoping to use this to help explain it to a buddy of mine and some people online that constantly ask on PS3 boards.

Let me know what you think.
