3.13 Auto sizing video measurement
The auto sizing video measurement module monitors horizontal and vertical flyback pulses and their relation-
ship to video content. In horizontal measurement, the HFLB is the reference signal. As PLL clock is the certain
multiple of HFLB frequency, the measurements for HFLB and R,G,BIN are all based on the PLL clock. In ver-
tical measurement, the VFLB pulse is reference signal and the HFLB is the counting clock. HFLB and VFLB
have an exact timing relationship to the active raster display on the monitor. When the HFLB, VFLB sync sig-
nals and the R,G,BIN video signals (taken from the output of pre-amplifier) are compared, it will feedback to
MCU a lot of information about the display size and centering. If back porch is much smaller than front porth,
then the video information is too much to the left (or up in the vertical direction). If both front porth and back
porth percentage of the total display period is too large, then the display size is too small. MCU can change
the display size and center until front and back porthes are equal and the porthes to active video ratio is cor-
rect. Please note that due to the deviation of analog circuits, building a ratio table of correct porches to video
for different operating frequencies is needed. And it is recommend that video contrast is set to maximum first
for the correct capture of video information.
