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.
