Broadcast and IPTV · MPEG-TS control plane

Keep channels flowing, correctly mapped and fully observable.

NoSignal is a production Linux application for ingesting, switching, conditioning and delivering MPEG-TS streams. It brings failover, packet-level correctness, HLS, EPG and operator visibility into one deterministic service.

The operator problem

Live transport fails in more ways than “up” and “down.”

Inputs freeze, continuity breaks, backups drift, service identifiers collide, multicast paths disappear and receivers reject streams that are almost—but not actually—compliant.

Failover must be fast without flapping between unstable inputs
Packet conditioning cannot become a CPU tax on passthrough channels
Operators need live state, history and safe changes without daemon restarts

The engineering response

Packet correctness inside an operator-first control plane.

NoSignal isolates channels, branches above unused processing, keeps packet work synchronous and bounded, and moves configuration changes through the web UI and API without restarting unrelated channels.

Per-channel runtime and output isolation
Conditioning runs only when the channel enables it
Metrics, alerts, SSE updates and runbook-friendly state are built in

Capabilities

From wire ingest to viewer delivery.

NoSignal covers the complete transport workflow while keeping protocol correctness, steady-state CPU use and operational clarity visible in the design.

01 · INGEST

Multiple transport inputs

UDP multicast, SRT, HTTP transport stream and HLS inputs, with interface-aware binding and health signals.

02 · FAILOVER

Controlled source switching

Priority inputs, warm standby, watchdogs, anti-flap behavior and auto-revert keep output stable through source failure.

03 · CONDITIONING

DVB-correct packet work

PID filtering and remap, PSI rewrite, continuity correction, service identity and optional CBR pacing.

04 · OUTPUT

Parallel delivery

UDP multicast, SRT, HTTP TS and built-in HLS outputs consume independently so one slow path cannot block another.

05 · EPG

XMLTV and EIT workflows

EPG import, mapping, service-aware injection and tools for resolving identifier collisions across channel lineups.

06 · OPERATIONS

Telemetry everywhere

Web console, REST API, SSE state, Prometheus metrics, alerts, live preview and companion iOS visibility.

System shape

Async at the edges. Deterministic in the packet path.

Inputs and connection-oriented outputs use asynchronous I/O. The transform pipeline stays synchronous and allocation-light, while each channel remains an isolated runtime unit.
