Remote Configuration
• Minimize Audio/Video Offset – checking this box enables a mode that adds
an internal video delay that matches the delay when bypassing the
SRC. When non PCM audio is detected on some of the AES input chan-
nels, the SRC’s for those channels are automatically bypassed. If
Low
Delay is selected on all channels, all SRC’s are forcibly bypassed and the
video delay matches the audio delay.
Refer to Table 9 on page 57 for specific lengths when using this mode.
This mode is most useful when the Sample Rate Conversion on the AES
input is bypassed which happens automatically when embedding a
Non-PCM (such as Dolby E) audio stream synchronous with the video.
This mode should be used when handling Dolby E streams.
Use this mode in conjunction with the Low Delay control for Sync PCM
audio on the Audio Input web page (
Audio Input Web Page on page 37 )
to reduce the audio processing delay (and audio/video offset).
