Hey maka, (Or anyone that is knowledgeable about 480i, 480p, 720p and 1080i.)
I have a couple more follow-up questions. You said that 480p means that the TV is showing all 480 lines of resolution at once. Meaning all 480 come one at once showing one still picture. Then it switches to another picture with all 480 showing the next frame in the action. Right? I am also assuming you mean 480 vertical lines of resolution. Then we have interlaced which shows the even lines only, with the odd lines turned off. Then the odd ones come on showing the next frame in the action with the even ones turned off. Back and forth and so on, correct? Well, if I have a HiDef TV that is capable of 1080 lines of resolution interlaced, and I am using only 540 lines at any given time during the interlacing process, how is this worse than 480p? Would not the 540i be displaying 60 more lines of resolution, resulting in a better picture? 480 lines of resolution does not sound like a lot. How does the number of lines of vertical resolution relate to my screen size? Does the size of the line (thickness) of resolution change from TV to TV? Can you explain in further detail?
Thanks again.
