Primary Master Control & Program Bus

24/7 continuous linear transmission with zero-downtime execution.

Direct3D11 zero-copy rendering engine driving master broadcast outputs. Displays active program clip countdown, upcoming preview event, real-time LTC/VITC timecode, and multichannel audio VU/PPM peak meters.

Frame-accurate transition execution:Sub-frame transition timing (cuts, dissolves, wipes, pushes) with frame-locked sync

Hardware decoding engine:Multi-format hardware NVDEC and DXVA2 decoding with Apple ProRes, Avid DNxHD, Sony XDCAM, and HEVC

On-air real-time compositing:Integrated station bug and lower-third overlay rendering without dropping frames

SMPTE master clock synchronization:Continuous LTC/VITC timecode tracking with NTP clock sync and real-time event countdowns
