BD30AV Series
Digital Audio Video Delay Line
BD30AV is the highest quality solid state audio & video delay line without data compression. The delay time could be set up to 60 seconds in increments of 1 frame steps.
Audio and video can be delayed together or separately in different amounts. 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.
