Frame Synchronisation
A BNC socket is used by the Decoder to frame
lock to an external video source. The frame
information is input as a composite synchronise
signal, with or without active video. The user can
offset the synchronisation to the video output by
±8 lines, with a resolution of 1 pixel. Lip sync
error introduced by the Receiver is in the range –
10ms to +30ms. This implies audio frame skip
and repeat.
The video and audio can be synchronised to an
analogue studio reference signal. This supports
both 625 and 525 frame locking.
This F Sync is activated through the Service menu
(#3). The specification for this connector is given
in Section B.4.4, Frame Sync Connector.
