Horizontal position Left/center/right justified output (shrink) or input (magnify)
Vertical position Top/center/bottom justified output (shrink) or input (magnify)
Horizontal ancillary data All horizontal embedded ancillary data (HANC) passed to output
Hot switch handling Module will handle input signal hot switched between synchronous signals that
are timed within the same line without causing glitches in the output stream
Switching line processing None
Vertical interval blanking Vertical interval active line time data optionally replaced by black or blanking –
20 or 21 lines blanked for 525; 25 lines blanked for 625 signals
Active line blanking Top and bottom 0, 1, 2, or 3 lines
In 525: Field 1 – 21 to 23 and 263 to 261; Field 2 – 20 to 22 and 262 to 260
