Crystal Vision Introduction
AVDELAY 3G User Manual R1.11 409/08/2016
The main features are as follows:
•Perfect for correcting large lip-sync errors: the relative audio/video timing can be
changed by several seconds in either direction, with independently adjustable
video and audio delay
•Can be used with any sources: accepts 3Gb/s, HD or SD input
•Use as many audio groups as you need: works with up to four groups
•Connect the outputs to a digital monitor: and make any adjustments by eye
•Cope with big differences between the audio and video: provides up to ten
seconds of video delay in SD, five seconds in HD and two seconds in 3Gb/s
(depending on video format), along with ten seconds of audio delay
•Lip-sync can be out in either direction: if the audio is earlier than the video, you
can delay the audio to let the video catch up
•Delay your audio channels differently: each mono audio channel can be assigned
to any one of four separate audio delay settings, or can bypass the delay
completely
•Flexible adjustments allow you to get the audio and video sync just right: with
the video delay adjustable in seconds and frames, and the four audio delays
adjustable in seconds, video frames and milliseconds
•Sophisticated handling of Dolby E: the audio delay applied to the Dolby E will
be rounded to the nearest time that gives the correct guardband alignment with
the outgoing video – and can be assigned to the four audio delay settings in the
same way as other audio
•Rapidly correct lip-sync errors: the audio will jump instantly to the new delay
setting
•Save time with a useful starting point for making your adjustments: three default
buttons allow all the video and audio delays to be set to 0, 5 or 10 seconds
•Optional integrated fibre input/output connectivity in a single frame slot: means
you won’t be limited by cable lengths
•Flexible control: select from board edge, front and remote panels, SNMP, GPIs
and PC software
•Saves rack space: the 100mm x 266mm module fits in Crystal Vision’s standard
frames and allows 12 AVDELAY 3G in 2U (24 in 4U, six in 1U and two in desk
top box)
