720p displays 720 horizontal lines at the same time 60 times a second resulting in a progressive image display also known as 720p.  1080i puts 540 horizontal lines up at a time, first the even then the odd lines, resulting in an interlaced picture 30 times a second, called 1080i.

720p is generally best suited for fast-moving action, such as sporting events while 1080i is generally thought to be ideal for shows where fast motion isn’t an issue, such as dramas and nature shows.

Here’s a look at the major broadcast networks and their choices:

• ABC – 720p
• CBS – 1080i
• Fox – 720p
• NBC – 1080i
• The CW – 1080i
