Caton Relay Server

Core Video Network Component

Caton Relay Server is a core component in your video network, managing multiple inputs and outputs, monitoring bandwidth and protocol transcoding, and providing the hub to bring your video distribution solution to the next level.


Flexible configurations

Caton Relay Server is flexible enough to build a wide range of video networks. Whether it is point-to-point, point-to-multipoint, or even multipoint-to-multipoint, Caton Relay Server makes designing workflow easy and powerful.

Point to Multi-point

Multi-point to Multi-point

Format Independent


Caton Relay Server is frame-rate and format independent, allowing you to manage video contribution and distribution with mixed video streams of SD, HD and 4K.

Protocol Translation Hub


Caton Relay Server fully supports industry standard protocols such as UDP, HTTP and RTMP, as well as having the industry leading Caton Engine for reliable cross-border and cross-continent contribution and distribution. Simultaneously, Caton Relay Server is able to transcode across protocols to make your video workflow easy.

Multiple I/O

Caton Relay Server support multiple network interfaces that can be individually configure for specific use, such as dual ISPs inputs or outputs for higher bandwidth or connection redundancy.  VLAN is also supported for complex video network setups.

Sophisticated Deployment. Simple Management


Caton Relay Server can be easily deployed to manage complex video contribution, yet maintain an simple management interface.  Caton Relay Server built-in web control helps you to remote control your video network.  

Manage and Monitor

Caton Relay Server can handle complicated video routing using Caton Engine R2TP and other protocol while fully monitoring active streams.  Keep track of key parameters including bandwidth, jitter, up-time and connection status. Caton Relay Server gives a peace of mind to your video contribution solutions.
