Overscan 1.1 is Out (NTSC only)
Overscan Scale 1.1 - (c) 2003 r6d2
Definitions
Frame size - The size in pixels of a given frame. For instance, 720x480. Some times this concept is confused with resolution, defined below.
Resolution - The actual information we can distinguish in an image. Analog NTSC 4:3 TVs are typically capable of delivering 427 horizontal lines of resolution.
What is this?
This is a NTSC SVCD image file which displays a given pattern on 7 different frame sizes (352x240, 352x480, 480x480, 528x480, 544x480, 704x480 and 720x480). Each of them is a separate chapter of the SVCD stream. The pattern has a scale which you can use to measure/adjust the overscan of your TVs.
An horizontal resolution measure pattern is also incorporated. Vertical lines are drawn "1 pixel wide and 1 pixel apart" for resolution of 1/1 DVD, 3/4 DVD, 2/3 DVD (SVCD), 1/2 DVD (CVD, VCD).
