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)
