Common composite TV formats with sub-carriers and their respective standards:
• NTSC - ITU-R BT.470-6
• NTSC# - SMPTE 170M
• NTSC#KA - SMPTE 170M
• PAL - ITU-R BT.470-6
• PAL# - ITU-R BT.470-6
• PAL#KA - ITU-R BT.470-6
Component television formats are named by their vertical resolution and scanning
method. These formats apply to RGB, YPbPr, YcbCr and HD-SDI video. In component
television format naming, the first three or four characters indicate the active vertical lines
in the format, the next characters indicate the frame tracing method, and the last two
optional characters indicate the frame rate.
Example
Active vertical lines
• 480 (active lines with 525 total lines)
• 1035 (active lines with 1125 total lines)
Frame tracing methods
• p = progressive
• i = interlaced
• s = segmented frame interlace (e.g., 1080s24, where a 24p frame is segmented into
two interlaced fields occurring at twice the frame rate - scene changes only between
field pairs – also known as "48sF")
• x = any – progressive, interlace, or segmented
Double clocking
• i2x = double-clocked interlace (scene may change between fields) pixels are
double-clocked for DVI compatibility)
