Composite television formats
Composite television formats are named by the standards defining them. The first three to
five characters of the format name indicate the color coding scheme. The first set of
characters refers to the standard. The next characters are optional and indicate
adjustments to the format. Examples of these formats are:
• NTSC (North American TV)
• PAL (European TV)
• NTSC-J - (where J refers to a Japan standard per NTSC without 7.5 IRE setup)
• PAL-N (where N indicates 3.58205625 MHz color sub-carrier)
• PAL# (where # indicates that the sampling rate is reduced to achieve square pixels)
Component standard definition television formats
Component SDTV formats are applicable in the case of RGB, YPbPr. These formats are
named by their vertical resolution, scanning method, and frame rate. The initial characters
indicating the resolution are followed by the scanning method. The two characters
following the scanning method indicate the frame rate. A typical example of component
standard or definition TV video format is:
• 480i2x30 (for a vertical resolution of 480 pixels with interlaced scanning and a 30 Hz
frame refresh rate; 2x indicates that the pixels are double-clocked for DVI compatibility).
Component high definition television formats
Component high definition television formats, like the standard definition television
formats, are named by their vertical resolution, scanning method, and frame rate. These
formats are applicable in the case of RGB, YPbPr, and YCbCr. These initial characters
indicating the resolution are followed by the scanning method. The two characters
following the scanning method indicate the frame rate. A typical example of component
high definition TV video format is:
• 1080i30 (for a vertical resolution of 1080 active vertical lines with interlaced scanning
and a 30 Hz frame refresh rate).
