Case Study

When the vendor withdrew support, the broadcast stayed on

A major infrastructure operator — more than 60 organizations nationwide and more than 100,000 employees — ran corporate TV from a headend built by its previous vendor. Support was withdrawn, and the broadcast to the sites could not stop: the network is isolated, and the video cannot go to a public cloud. A headend of their own, on Agora appliances, took its place. The signal is gathered at the center and sent into the internal network by multicast and unicast. If the primary server stops, the standby carries the broadcast.

Our Client

Company

A large infrastructure operator: critical network assets, more than 60 organizations nationwide, more than 100,000 employees

Industry

Transport and logistics infrastructure (B2B services to the sector)

Challenge

The corporate TV headend was left without vendor support, and the live broadcast still had to reach sites across the country. A separate connection from the center to every screen is more than the links between organizations can carry. The network is isolated: the video cannot leave it, and the equipment at the center has to run around the clock, fit a 19″ rack, and meet information-security rules.

Key Results

  • •The headend is under the manufacturer's support again: own appliances in place of equipment left without support
  • •The broadcast travels the internal network by multicast and by unicast — no public cloud, no stream per screen
  • •A failed primary server does not stop the air: the standby appliance takes over and hands the broadcast back when the primary recovers
  • •Role-based web UI, a dedicated security-auditor role, event logging, and syslog export to SIEM
  • •The broadcast does not depend on internet access

About the Project

Client's Goal

A major vendor withdrew support, and the corporate TV headend was left unattended. The replacement is a headend of their own: the signal is gathered from HDMI devices and over IP, encoded and transcoded on site, and sent by multicast and unicast into the isolated network. Sites across the country watch a stable broadcast, and one failed server does not stop the air.

Our Solution

At the headquarters the company deployed several Agora appliances — servers with preinstalled software in 19″ rack enclosures (up to 2U), running 24/7. The delivery set includes rack mounting, operational documentation, and ongoing support from the manufacturer.

Each appliance takes two kinds of sources. Over HDMI, up to four 1080p inputs: studio sources and media players. Over IP: cameras, network players, and broadcast servers, unicast and multicast. The appliances prepare 1080p and 720p profiles and deliver them into the internal corporate TV network both as multicast and as unicast (SRT, RTMP, RTSP, HLS, HTTP MPEG-TS, MPEG-DASH). Separate network ports on each unit carry playout and remote management.

Redundancy is at server level. Primary and standby appliances work as a pair: the standby waits while the primary is up, takes the broadcast on failure, and returns it after recovery. Administrators run the stack from the web UI. Security has a separate auditor role, retention of significant events, and syslog export to SIEM.

Results

Key Achievements

  • •Corporate TV no longer depends on the vendor that withdrew support
  • •The broadcast stays in a closed network: multicast and unicast leave the center, not a connection per screen
  • •A primary appliance failure does not drop the air — the standby server continues it
  • •Operations fit information-security requirements: roles, an event log, SIEM integration
  • •The broadcast does not depend on internet access
