If you are looking to implement or use an "HD Blanking" feature in a technical workflow, it generally involves these steps:

Used to generate a perfectly black or "blank" High Definition frame to calibrate equipment or check for signal noise. HDBlank

Use the blanking interval to "put together" or embed auxiliary data like closed captions, timecodes, or audio. If you are looking to implement or use

Use a Peak Power Analyzer or waveform monitor to ensure the blanking level is at a true "0" (black) and contains no stray signal noise. To help you more specifically, could you clarify: HDBlank

In hardware like FPGAs or SDI transmitters (e.g., Intersil ), "Blanking" features define the margins around the active video pixels.
