Find horizontal and vertical blanking counts by subtracting active pixels or lines from corresponding raster totals.
Description
Find horizontal and vertical blanking counts by subtracting active pixels or lines from corresponding raster totals.
Video Blanking Interval: Find horizontal and vertical blanking counts by subtracting active pixels or lines from corresponding raster totals.
When to use Video Blanking Interval
Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.
- Horizontal total (px)
- Required integer input.
- Horizontal active (px)
- Required integer input.
- Vertical total (lines)
- Required integer input.
- Vertical active (lines)
- Required integer input.
How Video Blanking Interval works
Find horizontal and vertical blanking counts by subtracting active pixels or lines from corresponding raster totals. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Horizontal blanking (px)
- The resulting horizontal blanking returned as an integer.
- Vertical blanking (lines)
- The resulting vertical blanking returned as an integer.
Limitations and assumptions
- Compact electronics formulas omit some combination of tolerances, temperature drift, bandwidth, loading, parasitics, noise spectrum, nonlinearity, clipping, calibration, layout, and device-specific limits. Typical datasheet values are not guaranteed limits.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.
