Lumantek DSK Live CG Generator (USB 3-Type Overlay)

The Lumantek ez-DSK is a Windows-based downstream keyer built for productions that need to overlay graphics — subtitles, logos, image sequences, widgets — onto an outgoing SDI or HDMI feed without adding a separate Fill/Key signal path. Its overlay technology inserts graphics with zero added delay and re-clocks every outgoing port for cleaner video, while doubling as a distribution amplifier that fans one source out to 4 SDI outputs and 1 HDMI output. A fail-safe trigger keeps video passing through even if the unit itself malfunctions, which matters for anyone running it live.

• Zero-delay graphics overlay: Applies subtitles, images, sequences, videos, and widgets onto the outgoing video without the extra video ports a conventional Fill/Key generator requires.
• Distribution and conversion: Fans a single input out to 4 SDI outputs plus 1 HDMI output, working as a distributor and converter at the same time.
• Fail-safe operation: A built-in fail-safe trigger mechanism keeps video passing through if the unit malfunctions.
• Signal re-clocking: Re-clocks the video signal on every outgoing port for improved video quality.
• Format support: Accepts SD through 1080p60 SDI input and up to 1080p30 CG input over USB 3.0.
