Composite television format names

882 Video Test Instrument User Guide (Rev A.35)
The generator has a built-in library of formats which are stored as XML files in any of the
generator's media. This section describes three sets of naming conventions for identifying
formats: 1) Composite television formats, 2) Component television formats, and 3)
Computer display formats. In addition, several miscellaneous naming conventions are
also described.
Composite television formats apply to RF, D2, CVBS, and S-VIDEO signal interfaces.
Composite television format names consist of a three to five character color coding
scheme indicator followed by optional characters that indicate format adjustments.
Example
Color coding schemes
• NTSC
• PAL
Adjustments to the format
• 4x == sampling rate is four times the color sub-carrier frequency
• 44 == NTSC with color sub-carrier frequency of 4.43361875 MHz (as opposed to 3.58)
• # == sampling rate is reduced in order to make pixels square
• jp == NTSC-Japan (NTSC without 7.5 IRE setup)
• -M == PAL with 3.57561149 MHz color sub-carrier and M timing (M/PAL Brazil)
