4. FLY WHEEL OPERATION
The flywheel logic will check the incoming video data for
valid video lines. If the incoming data represents a valid
line, the flywheel remains in sync with the incoming data. If
the incoming data represents an invalid line, the flywheel
will use the stored timing information for the past valid line
to generate the output HVF timing signals until three (3)
consecutive lines having identical timing are detected. In
this case, the new timing information will be saved and the
flywheel operation is updated to this new timing.
Mismatches between the HVF information decoded from
the data stream and that indicated by the flywheel will
trigger the EAV_ERR and SAV_ERR signals as shown in
Figure 3. HVF output timing is shown in Figure 2.
5. AUTOMATIC SWITCH LINE LOCK HANDLING
The automatic switch line lock is based on the assumption
that the switching of video sources will only cause the H
signal to be out of alignment whereas V and F signals
remain in sync; i.e. switching between video sources of the
same format. Therefore, when in the automatic switch line
lock mode (FAST_LOCK transitions for low to high), the
flywheel positive H signal transition will align with the
detected positive H signal transition. Timing for the
FAST_LOCK signal is shown in Figure 5.
