APPENDIX D – USING THE CVBS INPUT FRAME BUFFER
When a genlocked source is not available, as in the case of satellite receivers or consumer tape
machines, Image Server MAXX 2400’s internal input frame synchronizer will re-synchronize the
source. The frame synchronizer works by buffering incoming frames, and re-aligning them with
the genlock signal applied to the MAXX 2400. The output frame rate of the server is synchronized
to genlock. Note that if the input frame rate is different than genlock, then greater or fewer frames
will be present in the recorded file. The difference will not be noticeable in most circumstances,
since crystal time references are produced with accuracies in the range of 25 to 100 ppm, resulting
in a frame error after some hours of play time.
There are no operating controls for the frame synchronizer. It is disabled when the input is
referenced to genlock.
When using AES/EBU audio input from non-genlocked sources, turn on the Audio Rate
Conversion. (See Page 71.)
NOTE: The frame buffer does not process SDI inputs. Unreferenced SDI inputs require an external
frame synchronizer.
