System Integration Example (IP/SDI)

Smart Routing function*

This function allows KAIROS to virtually handle a larger number of input sources by automatically switching the video input to the network switch between the video stream state and the idle state as needed. This eliminates the need to consider the bandwidth limitations of the video that KAIROS can receive simultaneously, and allows KAIROS to virtually handle a greater number of inputs than the maximum number of inputs in Kairos Core itself.

For example, at 4K, the Kairos Core 2000 (AT-KC2000) has a maximum of 8 inputs but can virtually assign 64 video sources to a scene, layer, or button on each control panel.

By assigning virtual video inputs set in Smart Routing to scenes, layers, and buttons on each control panel in advance, KAIROS can switch from idle to streaming and output to the PGM with almost no delay by switching scenes or pressing a button during live production. Virtual input video sources can also be designated with thumbnails in Multiviewers, allowing smooth video production even with numerous inputs.

  • * Requires KAIROS ver1.7.1 or later.

Smart Routing input sources are marked with a Ⓐ mark to the left of the status mark. Sources with a gray mark are virtual inputs, and sources with a green mark are video signal inputs that can be used for output.

Agile Input Routing expands number of I/O

Input/output functions of KAIROS has been expanded and strengthened by the "Agile Input Routing" feature that flexibly allocates GPU I/O capability according to the bandwidth of video source.
For example, via the ST 2110 network, a single mainframe Kairos Core 2000 can simultaneously connect up to 64 inputs/40 outputs*.
This allows using in larger scale live productions with more scenes and more input sources.
KAIROS removes input restriction to be connected to a system and realize more efficient use of ST 2110 network and other inputs such as SDI*, NDI®, SRT and other streaming inputs.

  • * Requires KAIROS Software V1.6 or later.

Software-enabled function expandability and linkage

KAIROS is an IT-based open architecture platform, and allows expansion of functions and control of external devices with the additional software to provide high flexibility and expandability. By using various function options, it offers an efficient system design. The support of external protocols is continuously evolving and the flexibility of Kairos will allow future system expansion and integration.

Compatible with SNMP

SNMP has been added to the list of supported protocols in V1.7. The following KAIROS statuses can now be viewed from external devices linked via the network, and operations can now be smoothly linked with external devices, such as the ability to set up notifications when an alert is generated.

What is SNMP (Simple Network Management Protocol)?

This is a protocol for performing network management in a simplified manner. Although it was initially used for remote monitoring purposes, it is now being incorporated in broadcast systems that are designed for live broadcasting from the perspective of safe system operation and troubleshooting. By using SNMP, it is possible to identify devices in the event of a network failure, which is useful for rapid failure recovery.
