1+1 Redundant Playout Supervisor & Heartbeat Engine

Continuous health surveillance maintaining 99.999% transmission continuity.

High-availability clustering engine running active surveillance across Primary (Main) and Secondary (Backup) playout channels. Monitors process heartbeats, GPU render pipelines, and network link health.

Sub-second heartbeat surveillance:Continuous UDP/TCP heartbeat polling between primary and secondary playout servers

Deep telemetry health probes:Continuous monitoring of GPU decode health, video buffers, and OS stability

Automated state mirroring:Real-time playlist synchronization keeping both channels locked to identical frame offsets

Isolated dual network architecture:Redundant management and media IP links preventing split-brain conditions

View 02 / 03 · Sub-Frame Failover

Clean Sub-Frame Failover Switching Engine

Automatic transfer to backup transmission in under 40 milliseconds.

Triggers clean downstream hardware router switching upon detecting a primary channel anomaly. The switch occurs within a single video frame without audio pops, black flashes, or viewer interruption.

Sub-40ms clean switching:Ultra-fast failover triggers downstream routing switchers within a single video frame

Glitch-free audio crossfade:Seamless audio transition eliminating acoustic pops, clicks, or digital muting

Hysteresis safety lock:Configurable failover debounce timers preventing flapping during transient network blips

Universal router protocol support:Native integration with Blackmagic Videohub, Ross, Evertz, and Grass Valley routers

Real-Time Database & Playlist State Replication

Frame-accurate continuous synchronization of playout and graphics state.

Bi-directional replication engine syncing active playlist items, clip playhead offsets, loaded graphics templates, and manual override flags across both playout nodes with zero lag.

Frame-accurate playhead sync:Synchronous clip position tracking ensuring the backup node takes air without seam

Dynamic graphics state replication:Real-time mirroring of on-air lower thirds, tickers, and DVE overlay states

Seamless post-recovery resync:Automatic background resynchronization of primary node after maintenance reboot

Comprehensive audit logging:Complete chronological incident logs recording failover events with sub-second timestamps

1+1 & N+1 Redundancy Topologies

Monitors Main (Primary) and Backup (Secondary) playout servers over redundant network heartbeats.

Continuous State & Clip Synchronization

Keeps the backup playout engine in exact frame lock with the primary server, mirroring playlist state, active clip position, and graphic overlays.

Automatic Seamless Failover

Detects hardware crash, software exception, frame freeze, or network failure on the primary node.

Instantly triggers SDI/IP matrix router switchovers and activates the backup transmission stream without visible disruption on home TV screens.
