Figure 11. Sync Processing Filter
Vsync Filter and Odd/Even Fields
The Vsync filter is used to eliminate spurious Vsyncs, maintain
a stable timing relationship between the Vsync and Hsync
output signals, and generate the odd/even field output.
The filter works by examining the placement of Vsync with
respect to Hsync and if necessary, shifting it in time slightly.
The goal is to keep the Vsync and Hsync leading edges from
switching at the same time, thus eliminating confusion as to
when the first line of a frame occurs. Register 0x14, Bit 2 enables
the Vsync filter. Use of the Vsync filter is recommended for all
cases, including interlaced video, and is required when using
the Hsyncs per Vsync counter. Figure 12 and Figure 13 illustrate
even/odd field determination in two situations.
