One File, Many Paths: Fazzt Bridges Hybrid Networks

Delivering large files and video streams over modern networks is no small task—especially when your audience is moving, remote, or distributed across different infrastructures. Whether the content is a critical software update, real-time video feed, or entertainment file, reliability, efficiency, and speed are essential. That’s where KenCast’s Smart FEC technology shines.

Smart FEC (Forward Error Correction) forms the backbone of hybrid delivery systems, seamlessly bridging satellite, broadcast, and cellular infrastructure to ensure content arrives perfectly intact, even under the most adverse conditions.

Understanding the Diagram: Hybrid Architecture in Action

This diagram illustrates how a single movie file is prepared and distributed using KenCast's hybrid content delivery system:

1. File Preparation:

   • A source movie file is encrypted and encoded with Smart FEC, generating supplemental packets that allow the receiver to reconstruct missing data.

   • These FEC-protected segments are stored and queued at a central NOC (Network Operations Center) or server.

2. Multichannel Delivery:

   • The FEC-enhanced file is transmitted via multiple multicast paths:

     • Satellite multicast for wide geographic coverage

     • ATSC 3.0 multicast for terrestrial broadcast in connected vehicles or fixed receivers

     • 4G/5G multicast for mobile environments with lower latency and localized reach

3. Fallback via TCP/IP:

   • For receivers in patchy areas or to backfill missed packets, data may be delivered via unicast TCP/IP, ensuring complete file reconstruction without human intervention.

4. Onboard Reception:

   • The end device (e.g., a car-mounted receiver) collects all incoming packets from available paths.

   • Thanks to Smart FEC, the receiver can accurately reconstruct the file, even if portions were missed from one or more transmission paths.

   
   

This multi-network strategy gives content providers unprecedented reach, resilience, and efficiency without duplicating transmission efforts.

Real-World Applications

• Connected Cars and Trucks: Delivering entertainment, software updates, or navigation files to cars in motion.

• Rail, Maritime & Aviation: Ensuring file delivery even when a train or aircraft switches networks or coverage zones.

• Public Safety and Military Ops: Streaming live surveillance feeds and critical files to remote teams over satellite + cellular.

• Broadcast and Cinema: Distributing high-quality video to theaters and broadcasters without delays or packet loss.

A Unified System for Complex Environments

KenCast’s Fazzt platform makes this hybrid architecture not only possible but elegant and manageable. With centralized controls, queue management, and bandwidth forecasting, operators have full visibility and confidence in delivery success. Multicast and unicast work in harmony. Errors are corrected silently. Files arrive on time.

In short, Smart FEC isn’t just about fixing errors. It’s about eliminating uncertainty across complex networks and making reliable delivery routines, no matter the path taken.
