Dual-Layer Compression
Keyed dual-layer video compression with non-viewable layers and on-SoC dual-decoder orchestration.
Mechanism
A pre-encode pixel-domain three-component keyed obfuscation transform splits a high-precision video master into two complementary streams such that no single layer is viewable. The three components compose to break global spatial structure while preserving the local within-tile spatial correlation that natural-image codecs require for compression efficiency.
The decoder orchestrates two concurrent hardware decoder contexts on a consumer-class SoC with shared-PLL clock tree and a software-throttled rate-control synchronizer (the on-SoC software analog of Trinity's hardware sideband at single-SoC scale).
Prior-art differentiator
Existing scalable video coding profiles (SVC, SHVC, Dolby Vision Profile 7 FEL) require base-layer viewability for backward compatibility. DLC inverts that design constraint.
Naor-Shamir visual cryptography and the Murari 2024 MTAP destruction-of-spatial-correlation construction sacrifice the bulk of the codec's compression efficiency; DLC preserves correlation locally, holding the aggregate compression-efficiency cost against an unobfuscated split to a modest fraction of that penalty. CABAC-syntax-level encryption schemes operate after entropy coding on already-incompressible bits; DLC operates before entropy coding on raw pixels (a different layer of stack and not substitutable).
Counsel posture
Twelve-month conversion and PCT deadline 2027-05-01. Track One Prioritized Examination at non-provisional conversion recommended: the AOMedia AV2 specification finalized in late May 2026, raising the commercial stakes for enforcement-ready claims. AOMedia engagement target 2026-08-01 (ninety-day post-filing window). Permutation-only sub-claim subordinated at non-provisional drafting.
