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).
