BD30AV Series
HD/SD
Digital Audio
Video Solid State Delay Line
BD30AV
is the highest broadcasting quality solid state video audio
delay line without data compression which is separated into HD
& SD series. The delay time could be set up to 120
seconds
for HD-SDI signal and up to 720 seconds for SD-SDI signals by the
increments of 1-frame step.
BD30AV series could be easily used in the On-Air TV
broadcasting. The
frame by frame adjustable feature can be used in most of the Virtual
Sets. The independent audio
offset can be eliminated the lip Sync
problem.
Built-in full 10Bits time base
corrector and frame synchronizer which is compatible with both
NTSC or PAL video standard, BD30AV series audio video delay line
allows to feed
the unit with any embedded, de-embedded, digital or analog signals providing always
perfect levels and GenLock to its outputs.
Performing full 10-bit signal process and 32-bit internal
DSP processing, BD30AV offers exceptional DTV-Grade picture
quality with excellent AGC and CGC functionalities and top
quality color correction.
Live
talk shows, awards specials, telephone call-ins, courtroom TV,
breaking news, home shopping - part of the excitement of live
TV is that you never know what's going to happen next. But
that can be a big problem if "what happens next" is
an obscenity, a libelous statement, or a courtroom utterance
that should not be aired.
B&M gave more than a few hundred TV or radio
stations the perfect digital delays as the safeguard to handle
such eventualities.
