Variety of video inputs and outputs available for use
Compatible with various input and output signals
KAIROS fully supports baseband signal (12G/3G/HD-SDI)*1 and IP packet (ST 2110*2, NDI® High Bandwidth, streaming) input and output. In addition to RTP, RTMP, and RTSP, the SRT*3 streaming protocol is supported for superior stability and security. And it is equipped with 8 input channels and 2 output channels, and each channel can be set to selected protocol. Audio input/output is supported 16 channels each for NDI® High Bandwidth and SRT, and 8 channels each for RTMP and RTSP.*4
- *1: Requires KAIROS software V1.6 or later and SDI I/O Board AT-KC20M1. Consult with your Panasonic dealer about SDI I/O board AT-KC20M1 installation.
- *2: AT-KC200L1 will be supported in the future.
- *3: SRT stands for Secure Reliable Transport.
- *4: For RTSP, only input is supported. Note that RTSP input does not work with the AW-HE130W/K (Discontinued) and AW-HR140 PTZ cameras.
- * NDI® is a video connectivity technology and is registered as a trademark by Vizrt NDI AB in the United States and other countries.
System Integration Example (IP/SDI)
- * AT-KC200L1 supports SDI input and output without SDI I/O board.
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 200 (AT-KC200) 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.
- * AT-KC200L1 needs option NIC board (future support).

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*1 network, a single mainframe Kairos Core 200 can simultaneously connect up to 64 inputs/40 outputs*2.
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® High Bandwidth, SRT and other streaming inputs.
- *1: AT-KC200L1 will be supported in the future.
- *2: Requires KAIROS Software V1.6 or later.

Processing by the GPU for flexible video expression
Layered effects with unrestricted number of MEs
Unlike the conventional hardware-based switcher, KAIROS is unrestricted by the number of MEs or keys. Layers can be added as the GPU capacity permits similar to the layers of a standard image-editing app, allowing you to set the keys and scaling freely.
The Kairos Core 200 in particular has significantly increased the number of layers by increasing the GPU video processing capacity to enable more complex and advanced video expressions.
System software V1.5 includes 2.5D DVE support (rotation and position adjustment using X, Y and Z axis).
Various video effects using layers
Diverse effects with title generator
Layers can be added with not only keys but also various effects. The built-in title generator allows you to create titles.
Add several new effects
From V1.7, several new effects are also added, which enables adjustment of effects with parameters.

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.
