Thåst Signal Genesis
TSG is a collection of tools for measurement, verification, reference generation and calibration. Built to stay readable in an OB gallery or PCR/ROC and predictable under load.
Operational readability
Designed for quick parsing at an engineering position, in a gallery, or in an OB. Graticule logic is part of the instrument.
Calibration and intent
Reference levels, time constants, holds, and gates are explicit parameters. Measurements are useful when the assumptions are visible.
Lean runtime
Web-native rendering with minimal moving parts. Transient response is preserved. Predictable behaviour is the feature.
Tools
Timing, analysis, and control.
Reference
Monotonic-backed broadcast clock with NTP synchronisation. Sub-millisecond precision, no backward jumps. EBU Tech 3335, SMPTE ST 2059 aligned.
Measurement
Loudness metering with M/S/I, LRA, gating, and true peak. Programme monitoring and compliance.
Test signal generator. Colour bars, tone, slates, alignment helpers for confidence checks.
Broadcast mpv configuration. SMPTE timecode, 16-channel audio routing, R128/A-85 loudness.
Control
Real-time playout monitoring. EVS-style overlay, multi-device dashboard, countdown displays.
Frame-accurate synchronisation for up to 20 CasparCG nodes. Drift correction, seamless resync.
IP video monitoring for MediaMTX. Live RX/TX dashboard, signal flow visualisation.
Engineering principles
- Deterministic timing: one clock source, no competing loops.
- Measurement clarity: scaling, gates, and holds are always explicit.
- Operator usability: readable from racks to gallery.
Broadcast reality
- Works for A1/A2 and engineering: numbers are stable and defined.
- Works for vision and shading: scopes prioritise verification.
- Works under time pressure: the UI avoids hidden modes.
- Scales from PPU to distributed multi-venue.
Standards and reference points
Where measurement is concerned, terminology and assumptions matter. These references are listed so the behaviour is unambiguous.
• EBU R128 / ITU-R BS.1770 (loudness, gating, K-weighting)
• True peak (oversampling, dBTP)
• Operational PPM: Nordic, BBC, DIN
• AES67 / ST 2110 aware
• PTP-conscious timing model• Reference level is part of the UI, always visible
• Time constants and peak holds follow EBU Tech docs
• Suitable for contribution, TX, and compliance monitoring
• Graticules are calibrated to specification
• Fits audio, vision, and engineering workflowsContact
Genesis
Let operators and engineers see what is happening, reliably, with calibrated context. Everything else is optional.
