Double clocking

• i2x = double-clocked interlace (scene may change between fields) pixels are

double-clocked for DVI compatibility)

Frame rate

Frame rate is optional. If no frame rate is given, then the frame rates are assumed.

• 24 = 24 Hz

• 60 = 60 Hz

Common component TV formats

• 480pLH Component SDTV signal containing letterboxed 16x9 high-definition content

• 480pSH Component SDTV signal containing anamorphically under-sampled 16x9

Computer display format names

Computer display formats are assumed to use progressive scanning. In computer format

naming, the first three characters indicate the vendor ID using the EISA ID (for example,

IBM, SUN, VSC) or the display type, the next two characters indicate the approximate

horizontal resolution, the next two digits indicate the frame rate (which will be half the field

rate with interlace scanning), and the final character designates the aperture (used only

when the aperture is not A).

Example

Vendor ID (EISA)

• SMT for VESA (digital) Safe Mode Timing

• DMT for VESA Standard Discrete Monitor Timing

• GTF for VESA Generalized Timing Format standard

• CEA for Consumer Electronics Association

• EIA for Electronics Industries Association (CEA)

Approximate horizontal resolution examples

• 02 for 256 pixels

• 09 for 960 pixels
