Output lip sync [OUTPUT LIP SYNC]

Since video signals and audio signals are processed on different circuits, time lag between the lip movement
and audio is developed. The time lag can be corrected by the lip sync correction function.
With this menu, you can set the lip synch value to delay the audio in order to match it with the video. The MSD
can delay audio signals by one frame.
You can set this function for each output using this menu and for each input by following " 7.8.6". Normally, set
it for each output to delay audio depending on the video delay amount of the display device. In case the video
source itself contains the gap between the video and audio, or video is delayed by connecting a frame
synchronizer for input, set lip sync for each input.
･Lip sync: 0 to 8 frames [Default]: 0 frame
Note:
Up to eight frames using lip-sync can be set for each output and input, but if the total number of frames for
output plus input exceeds eight frames, the maximum number of delayed frames is limited to eight frames. If
sampling frequency of the audio signals (sampling frequency of input signals or digital input; the set value of
"7.8.7" for analog input) is 88.2 kHz or more, the amount of delay is also limited. For example, if sampling
frequency is 192 kHz, only two frames are delayed even though lip-sync is set to three frames or more.

1080p@50), the maximum delay is four frames.
