Kramer KDS-8 Zero Latency 4K HDR SDVoE Video Streaming Transceiver over Copper

Product Overview

The Kramer KDS-8 is a zero-latency 4K@60Hz (4:4:4) SDVoE video streaming transceiver for AV-over-IP distribution over a 10G copper Ethernet network, deployable as either an encoder or decoder in the same unit. AV system designers and integrators use the KDS-8 to build scalable, software-defined AV matrix systems — including video walls, multiviewers, and point-to-multipoint distribution — over standard network infrastructure without dedicated coax or HDMI cabling. It supports HDCP 2.2, HDR, and full 4:4:4 chroma, making it suitable for 4K content distribution in corporate, education, and broadcast environments. The KDS-8 is fully SDVoE-compliant, ensuring interoperability with other SDVoE-certified hardware and software platforms.

Product Description

The KDS-8 encodes an HDMI input signal — along with IR, RS-232, and analog audio — and streams it over a 10G IP network to any number of decoder units. In decoder mode, it receives the encoded stream and outputs HDMI to a connected display. This bidirectional flexibility means a single unit serves as either a transmitter or receiver, simplifying inventory management for integrators. The SDVoE codec delivers lossless compression with zero perceptible latency, critical for interactive applications such as digital signage with touch overlay, video conferencing, and live event production. Genlock and Fastswitch modes minimize switching disruption in multi-source environments. The KDS-8 works with a 10G managed network switch supporting multicast, jumbo frames, and IGMP snooping — and the optional KDS-8-MNGR management appliance adds virtual matrix routing, video wall, and multiviewer configuration via a central web interface. Analog audio embedding and de-embedding allow integration with room audio systems independently of the HDMI stream. Bidirectional IR and RS-232 over IP extend device control to the far end of the network link without separate control cabling.

Key Features
