Format naming conventions
The names used in the built-in format library have been updated for the generator. Many
format names on previous versions of the 802 generators have been renamed to more
closely match the naming conventions used in the display industry or in the appropriate
standards. There are three sets of naming conventions described in this section: 1)
Composite television formats, 2) Component television formats, and 3) Computer display
formats. In addition, several miscellaneous naming conventions are also described.
Composite television format names
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
• SECAM
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)
• -N == PAL with 3.58205625 MHz color sub-carrier (N/PAL Argentina, Paraguay,
Uruguay)
• -N == NTSC color encoding with N timing (NTSC-N)
• -60 == PAL format that allows NTSC tape playback on PAL TV (PAL-60)
• plusKKKK == Enhanced wide-screen PALplus TV transmission system
• p == progressive video game signal (for example, NTSCp or PALp)
