  • * Deltacast FLEX modules are required for baseband input/output.
  • * When using Deltacast and ST 2110 simultaneously, the Deltacast port connection will be 4 ports.

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, up to 64 inputs* and 40 outputs* of 1080i and 720p signal can be connected to on a single mainframe with ST 2110 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 ST 2110 network and other inputs such as Deltacast, NDI® High Bandwidth, 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.
