NOTE…
These connectors are shared with the ASI output, under the control of menu 5.1.
2.8.6 Frame Synchronisation
A BNC socket is used by the Decoder to frame lock to an
external video source (NTSC, PAL or SECAM). The frame
information is input as a composite signal, with or
without active video. The user can offset the
synchronisation to the video output by ±8 lines of the
reference signal, with a resolution of 1 pixel of the
reference signal. Lip sync error introduced by the
Receiver is in the range -10 ms to +30 ms. This implies
audio frame skip and repeat may occur.
This Frame Sync is activated through the Service menu
(Menu 3).
