Trinity

Mechanism

A digital logic device hosts per-decoder asynchronous dual-port FIFOs, a hysteretic watermark comparator, and a physically separate sideband signaling path that phase-locks plesiochronous discrete video decoder ICs to a master clock domain. The sideband commands decoders to extend their vertical blanking interval when their associated FIFO fill exceeds a high watermark, enabling scanline-accurate additive pixel-domain composition with saturating arithmetic across three fidelity-partitioned streams.

Prior-art differentiator

Sideband synchronization claims rest on a physically distinct signaling path electrically isolated from the high-speed video data interface. The closest prior-art references in the resolution-layering and predictive-decoder cluster do not teach the combination of asynchronous dual-port FIFO at scanline granularity plus hysteretic-watermark-driven blanking-interval modulation plus pixel-domain additive composition.

The foundational 1990s-era Demos and Demografx resolution-layering patents have expired or expire through 2026, opening a clean freedom-to-operate window. Trinity uses additive-only reconstruction, fundamentally different from the predictive-encoder approach in the Dolby Vision Profile 7 ecosystem.
