The independent audio offset can be eliminate the lip Sync problem. BD30AV series could be easily used in the On-Air TV broadcasting. The frame by frame adjustable feature is used in most of the Virtual Sets. Built-in 10Bits time base corrector and frame synchronizer, 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. Both digital embedded signal, digital SDI video, analog composite or component video and digital AES/EBU, analog balance XLR audio I/O are available on one unit depend on the different customers' requirements.
