BD30AV
is the highest broadcasting quality solid state video audio
delay line without data compression which is separated into 4K
UHD & HD/SD series. The delay time could be set up to 720
seconds
for U HD-SDI signal and over 3600 seconds for HD-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 all
of the UHD/HD & 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.
