• Aspect Ratio is the proportion between the width and height of a TV screen
   
• Resolution defines the amount of pixels displayed on the screen
   
  • 4K (Available on some TiVos)
     
  • 1080p  (Available on TiVo)
     
  • 1080i
     
  • 720p
     
  • 480i (Standard Definition)
     
  • i or p refers to the scanning technology
     
    • i = Interlaced scanning technology. It scans and refreshes even and odd lines separately, but produces very sharp pictures in general when the image is still or has little motion
       
    • p = Progressive scanning technology (newer). Scans and refreshes all lines at the same time. Progressive scanning produces smoother motion with less blurring. It's perfect for high action movies and sports.
