Variety of video inputs and outputs available for use

KAIROS fully supports baseband signal (12G/3G/HD-SDI, HDMI, Display Port) and IP packet (ST 2110, NDI®*1, RTP) input and output. In addition to RTP, RTMP, and RTSP, the SRT*2 streaming protocol is supported for superior stability and security. And it is equipped with 8 input channels of Kairos Core 1000 or 6 input channels of Kairos Core 100 and 2 output channels, and each channel can be set to selected protocol.*3 Audio input/output is supported from KAIROS version 1.2.2: 16 channels each for NDI® and SRT, and 8 channels each for RTMP and RTSP.

  • *1: NDI® is a new protocol developed by NewTek, Inc. that supports IP video production workflow. NDI® is a registered trademark of NewTek, Inc. in the United States. In this instance, NDI® is used to indicate low latency with high bandwidth NDI®.
  • *2: SRT stands for Secure Reliable Transport.
  • *3: For RTSP, only input is supported. Note that RTSP input does not work with the AW-HE130W/K (Discontinued) and AW-HR140 PTZ cameras.

System Integration Example (IP-based)

System Integration Example (SDI-based)

  • * Deltacast FLEX modules are required for baseband input/output.
  • * When using Deltacast and ST2110 simultaneously, the Deltacast port connection will be 4 ports. (AT-KC100 only)

New Agile I/O expands number of I/O

Input/output functions of KAIROS has been expanded and strengthened by the new "Agile I/O" feature that flexibly allocates GPU I/O capability according to the bandwidth of video source.
For example, up to 64 inputs* and 40 outputs* of 1080i and 720p signal can be connected to on a single mainframe with ST2110 network.
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 ST2110 network and other inputs such as Deltacast, NDI®, SRT and other streaming inputs.

  • * Input and output totals are on a best-effort basis using the Kairos Core 1000 mainframe and 1080/60i or 720/60p video for all I/O sources. The Kairos Core 100 with the AT-SF002 I/O option offers a maximum 48 inputs and 32 outputs.

PTP synchronization

KAIROS supports PTP (Precision Time Protocol) synchronization, which is an IP-based synchronization and can fully manage the whole ST 2110 systems. Supports PTP synchronization even with a GbE (Gigabit Ethernet) port connection.

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 1000 in particular has significantly increased the number of layers by increasing the GPU video processing capacity to enable more complex and advanced video expressions.

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.

Format-free Canvas

The Canvas function enables the production of videos in a special format, such as 32:9 for wall display, in addition to the standard 16:9 format. Up to 8K (32M pixels) resolution is supported. With the freely customizable multiviewer, videos with unique aspect can be displayed as is.

  • * The Canvas function is a standard feature of the Kairos Core 1000. With the Kairos Core 100, the AT-SF003 Canvas option is required, and the AT-SF001 4K option is required for 4K output. In either case, some functions are being depended on the GPU performance level.

The multiview displays a 32:9 format screen

Short one frame latency and variable frame delay

The KAIROS processing latency can be as low as one frame. Sports and concert performances can be presented with the action intact.
A variable frame delay (1 to 20 frames per 1 frame step) can be conducted for each channel, and the frame delay difference between the sources can adjusted.

The KAIROS processing latency can be as low as one frame.

Video/audio/still picture file retention

With the built-in RAM Player, Clip Player and Audio Player*, footage can be played loaded video/audio files.*1 A playlist function has been added to the Clip/RAM player. It also has a still picture storage.

  • * The audio player has been added since version 1.2.2
  • RAM Player (8 channels, uncompressed)

    Uncompressed images can be played, making it suitable for playing relatively short videos such as background video loop playback and flying logo. The recording time depends on the RAM capacity of the Kairos Core 1000 and Kairos Core 100, and increases according to the material image resolution and number of channels (up to 8 channels). Clips are imported externally and saved onto the internal SSD.

  • Clip Player (2 channels, compressed)

    It is possible to play compressed video files with audio, making it suitable for playing relatively long clips such as commercial footage. Clips are imported externally and saved onto the internal SSD. It supports AVC-Intra, H.264, and Avid DNxHD video file formats. In addition, Apple ProRes*2 is supported.

  • Audio Player (4ch)

    Audio files can be played. File formats supported are WAV, MP3, Ogg, FLAC and AIFF; files other than WAV will be converted to WAV (48kHz/24bit) upon upload.

  • *1: The Kairos Core 100 requires the AT-SF001 4K option during 4K playback.
  • *2: Compressed video files with interlaced video format are not supported.
    Note: Playing compressed video files depends on video resolution, NLE system by which the video files are made, and performance of Kairos Core CPU. Please confirm video files playback capability with Kairos before starting production.
