dvb-ci-runtime

Pure-Rust EN 50221 DVB Common Interface runtime — the driver loop over the dvb-ci wire codecs.

dvb-ci is no_std and owns the wire layer (TPDU / SPDU / APDU parse+serialize, CA_PMT building, CI Plus extensions). dvb-ci-runtime adds the runtime: device I/O, the TPDU poll loop, SPDU session management, and the per-resource state machines that drive a physical CAM (ETSI EN 50221, TS 101 699).

Design

Everything is written against the CaDevice trait, so the runtime runs against either a real Linux CA device (/dev/dvb/adapterN/caM, the linux feature) or an in-memory MockCaDevice. The mock makes the state machines testable without hardware and enables differential testing against an external reference — drive both with the same scripted mock CAM, assert the emitted write/ioctl byte sequences match.

Implemented from the EN 50221 specification.

Status

Foundation: the CaDevice abstraction + mock. TPDU/SPDU/resource state machines and the Linux device implementation land incrementally.
