Compliance — Three-Tier Review + Grade Protection
Every playout asset passes three independent review stages — music, AI host voice, schedule — before it reaches the air. Wrapped in a three-layer cybersecurity stack that meets China's Information Security Multi-Level Protection grade 2 / 3 requirements, and maps onto regulators elsewhere via configuration.
Six layers, two rings
Three review tiers cover content. Three security layers cover the perimeter. Together they replace the audit binder.
Music review tier
Every track ingested into the library passes lyric, language and licence checks before it can be scheduled — flagged tracks never reach the queue.
AI host voice review tier
AI-generated voice segments are reviewed against editorial policy and pronunciation rules before release. Voice library updates do not bypass review.
Schedule review tier
The daily clock passes a final review for content adjacency, regulator rules and station policy before it goes live — nothing reaches air without sign-off.
Hardware air gap
Physical isolation between the production network and the on-air host. Operator workstations cannot directly mutate the playout server.
Software dedicated gateway
Bi-directional data validation on every payload crossing the air gap. Schema mismatch or out-of-policy content stops at the gateway.
wav9 audio firewall
A custom audio-format defence against externally-tampered files. wav9 wraps the audio with integrity metadata that downstream players verify before play.
Compliance is the playout chain
KAVANA bakes review and security into the playout chain itself — not as an audit step bolted on at the end. The regulator's spreadsheet is the same data the operator sees on the dashboard. When a rule changes, the change ships in a configuration update rather than a retraining cycle.
