Software & Hardware-Ready Engine / SMPTE Timecode, Timestep (Hz) & PTP/gPTP Master Clock
Abu Clock
Cross-platform software and hardware-ready timing engine engineered to deliver broadcast-grade SMPTE ST 2059-1 / ST 12-1 timecode (HH:MM:SS:FF.sf) and deterministic frequency timestep (Hz) synchronization across standard local area networks (Gigabit Ethernet, USB-C LAN, and Wi-Fi). Designed as the temporal backbone of the Abu ecosystem alongside Abu Track & Scan and Abu Cam, it bridges Virtual Production (VP), AR broadcast, and 3D Gaussian Splatting (3DGS) spatial capture pipelines with enterprise broadcast timing.
