11.1.1 Video Timing Parameter Definitions

•

Active Lines Per Frame (ALPF) - Defines the number of lines in a Frame containing displayable data: ALPF

is a subset of the TLPF.

•

Active Pixels Per Line (APPL) - Defines the number of pixel clocks in a line containing displayable data:

APPL is a subset of the TPPL.

•

Horizontal Back Porch Blanking (HBP) - Number of blank pixel clocks after Horizontal Sync but before the

first active pixel. Note: HBP times are reference to the leading (active) edge of the respective sync signal.

•

Horizontal Front Porch Blanking (HFP) - Number of blank pixel clocks after the last active pixel but before

Horizontal Sync.

•

Horizontal Sync (HS) – Timing reference point that defines the start of each horizontal interval (line). The

absolute reference point is defined by the “active” edge of the HS signal. The “active” edge (either rising or

falling edge as defined by the source) is the reference from which all Horizontal Blanking parameters are

measured.

•

Total Lines Per Frame (TLPF) - Defines the Vertical Period (or Frame Time) in lines: TLPF = Total number

of lines per frame (active and inactive).

•

Total Pixel Per Line (TPPL) - Defines the Horizontal Line Period in pixel clocks: TPPL = Total number of

pixel clocks per line (active and inactive).

•

Vertical Back Porch Blanking (VBP) - Number of blank lines after Vertical Sync but before the first active

line.

•

Vertical Front Porch Blanking (VFP) - Number of blank lines after the last active line but before Vertical

Sync.

•

Vertical Sync (VS) - Timing reference point that defines the start of the vertical interval (frame). The absolute

reference point is defined by the “active” edge of the VS signal. The “active” edge (either rising or falling edge

as defined by the source) is the reference from which all Vertical Blanking parameters are measured.
