RTLZWEI uses Panasonic’s KAIROS to broadcast its internal events to customers and employees

The pandemic changed the way that RTLZWEI television celebrated its internal events. “It was quickly clear to us that our internal productions and events – which we organise for business partners or our own employees but not for a broad television audience – would have to take place online and remotely,” explains Dirk Kolditz, Head of Technology Operations at RTLZWEI. That was the only way for RTLZWEI to remain accessible.

That was the criteria that the broadcaster had to follow: Any technical solution for remote productions should work well with the existing infrastructure; it should also be easy to integrate into the network; the device should be ready to use and play content in UHD; in addition, RTLZWEI did not want to use traditional SDI. All those reasons, in words of Dirk Kolditz, made Kairos from Panasonic the chosen one.

Kairos is a native IP system, is easy to use with Panasonic cameras such as PTZ cameras, handhelds camcorders and AK-UC4000 4K live camera systems. The platform balances the entire processing load without imposing the configuration limitations of standard hardware-based systems. The solution also offers numerous input, output and operating options for efficiently producing live videos while the Kairos KC1000 hardware in use leaves enough power reserves for future applications.

KAIROS works well with the existing video infrastructure at RTLZWEI, including SMPTE ST 2110. The platform is server-based and not limited to dedicated hardware. Multiviewer as well as clip and RAM player are already integrated. KAIROS offers flexibility making it possible, for example, to overlay a HD graphic on UHD material. Users benefit from the scalability of mix/effects through the layers they can create and move with the graphical user interface.

RTLZWEI currently uses KAIROS for internal productions and events for business partners or its own employees. KAIROS acts as an image mixer, controls the graphics, and streams in UHD. For example, the company transmitted the road shows of the channel’s advertising marketer. That show was streamed to advertising customers and agencies. Between the presentations, reports and professionally designed, longer trailers are transmitted through KAIROS. Animated lower thirds and a permanent logo are also deployed – all controlled and managed through KAIROS. And it doesn’t matter if the production takes place in a virtual studio with a green screen, in a real studio, or both: “All together, we had two studios and nine cameras in operation,” Kolditz explains. “On top of that, there were the presentations which were fed directly to KAIROS over NDI.”  Such shows, despite their complexity, can be entirely produced with KAIROS.
