An excerpt from this page:
|The 18 ATSC Digital TV Formats|
My notes about the table above...
|60i means 60 interlaced fields per
second, or 30 frames per second.|
Two fields make a complete picture frame. One contains the odd scan rows; the other contains the even rows.
Note that each pair of fields in a frame could have been recorded from the same moment in time, but are typically 1/60 of a second apart.
| 60p means 60 progressive frames per second.
Likewise with 24p and 30p.|
All rows are scanned in one pass (row 1, 2, 3, 4, etc.) from top to bottom. So the entire frame is recorded at the same moment in time typically.
