Synchronization of multiple streams of audio, video, or both — audio and video
timing is maintained from a source across encoders preserving lip sync quality and
supporting multi‑source streaming applications.
Decoder genlock connection for synchronized decoding — supports synchronized
decoding of source streams across multiple VND 250 decoders.
EDID emulation — provides selectable resolutions and refresh rates, ensuring optimal
resolution and format between video sources, encoders or decoders, and displays.
Auto-Image setup — when activated, the unit automatically detects the resolution of
the incoming video signal and sets the total pixels, active pixels, and active lines, as well
as the horizontal and vertical starting points. This can save time and effort in setting up a
newly connected source, particularly in presentation environments where the input is not
connected to a fixed source, but instead goes to an open connection for a presenter’s
laptop.
Decode at native resolution or scale to match display resolution — configure
decoders to output the original source resolution or to scale incoming streams to match the
display resolution and maintain clean switches when new source streams are selected.
Aspect ratio control — the aspect ratio of the decoder output can be controlled by
selecting a FILL mode, which provides a full screen output, or a FOLLOW mode, which
preserves the original aspect ratio of the original source signal.
HDMI compliant — both the encoder and decoder support RGB and YCrCb source
formats.
HDCP compliant streaming — supports streaming of HDCP‑encrypted signals commonly
used in AV environments.
Key Minder continuously verifies HDCP compliance — authenticates and maintains
continuous HDCP encryption from sources to encoders and decoders to displays ensuring
reliable streaming of HDCP compliant displays.
HDCP Visual Confirmation provides a green signal when encrypted content is sent
to a non-compliant display — a full‑screen green signal is sent when HDCP‑encrypted
content is transmitted to a non‑HDCP compliant display, providing immediate visual
confirmation that protected content cannot be viewed on the display.
Audio —the VNM 250 incorporates:
z
Bi‑directional audio streaming. Two‑way audio streaming supports bi‑directional audio
communication between encoders and decoders.
z
HDMI embedded audio and analog stereo encoder inputs.
z
HDMI audio embedding or de‑embedding by decoder. Audio signals can be embedded
onto the HDMI output signal or extracted to the analog stereo output.
z
Audio breakaway streaming. Stream audio to decoders independently of associated
video sources. (This feature requires a VNM Enterprise Controller.)
Alarm relay — provides contact closure notice of warnings or alarms to control systems for
proactive system monitoring and fault resolution.
Front panel LCD interface, buttons, and rotary encoders — provide access and
control over device status and system data, simplifying system setup and operation.
Front panel LEDs — offers quick visual indication of device, system, or streaming status to
simplify commissioning activities and troubleshooting.
VLAN Tagging — simplifies management of encoders and decoders, making management
and operation on multi‑purpose networks simple.
Local Ethernet control port — offers the flexibility to connect a control device to the
VN‑Matrix 250 unit simplifying network cabling for the streaming system.
