Key Digital Introduces Second-Generation Modular AV-over-IP Systems — KD-IP922-II, KD-IP1022-II

KD IP922 & KD IP1022Key Digital has introduced its second-generation modular AV-over-IP systems, the KD-IP922-II and KD-IP1022-II encoders and decoders for 4K. An HDMI-to-IP encoder per source feeds the managed switches, and an IP decoder per destination display converts the desired source signal back to HDMI to feed monitors and projectors. USB 2.0 routing follows AV source/display selection with a maximum of four USB keyboard or mouse devices simultaneously routed to a single host computer/encoder. A KD-IP1022-II AV-over-IP system extends the capabilities of a KD-922-II system by providing asymmetrical KVM routing and deploying firmware that offers mosaic video wall management.

Control is delivered with content in Key Digital AV over IP systems. The three multi-function ports on each decoder and encoder — configurable for bidirectional IR and RS-232 or voltage trigger — may be used as Compass Control Pro master controllers for control of and by Compass Alliance partner hardware, by IP control systems via KeyCode open API or as a control interface for third-party devices.

The KD-IP922ENC-II encoder has an MSRP of $960, while the KD-IP922DEC-II has an MSRP of $833 — though the KD-IP922-II series maintains full backward compatibility with IP822/IP922 hardware. The KD-IP2022ENC-II encoder has an MSRP of $1,152, while the KD-IP1022DEC-II has an MSRP of $1060.

De-embedded two-channel analog outputs (one for each encoder and decoder) provide volume, muting, 3-band EQ and lip-sync delay control. The key addition to the KD-IP922-II and KD-IP1022-II encoder feature sets is digital audio de-embedding via a provided TOSLink optical output with support for DolbyTrueHD, Dolby Digital Plus, Dolby Atmos and DTS-HD Master Audio multichannel audio protocols. In addition, the encoders retain an HDMI pass-through, which can be used as a local audio source and a local video source. Multichannel audio at the decoders can typically be de-embedded and delivered by the destination monitor.

Key Digital AV-over-IP system specifications claim 4K resolution support up to 4096×2160/30Hz/12-bit at 4:4:4; transmission to 10.2Gbps bandwidth and visually lossless compression to 18Gbps; selectable 4K to 1080p/720P down conversion; EDID display identification handshaking (with an internal library featuring 15 default EDID configurations); HDR10 and fully licensed HDCP 2.2 support and compliance; full support of the latest HDMI capabilities; and a Full Buffer System, which manages TMDS re-clocking/signal re-generation, HDCP authentication with source and display, EDID control handshaking and hot plug control that enables an integrator to choose if active signal voltage is forced to connected input devices. The encoders provide HDMI extension up to 330ft / 100m @ 4K 24/25/30(4:4:4) into the network switch or point-to-point.

Using the UHDoTP (Ultra High Definition over Twisted Pair) 4K-to-1080p/720p down-convert feature allows integrators to mix display models and capability within a system, accommodating integration of new and legacy displays by giving the option to choose where this feature should be enabled per output.
