1. INTRODUCTION
Video conferencing is an important and convenient way to communicate
with people around the globe. If you want to express your thoughts clearly
by sharing a variety of rich images, an integrated machine with multi-
windowing and video capture functions is a splendid idea. This Multiviewer
with Streaming Solution for Video Conferencing is just the thing to meet
your requirements. Besides being a high performance HDMI matrix switch
with integrated scaling and multi-windowing technology, a video capture
component is also included!
Any of 4 different HDMI sources may be displayed individually, full screen,
with seamless switching in Matrix mode, or they can be displayed using
a variety of multi-window modes including standard views like PiP and
PoP as well as fully customizable quad-window modes. By using an HDMI
cable to connect between the multiviewer component’s output and the
video capture component’s input above it, the unit is transformed into a
flexible video streaming, distribution, and recording powerhouse. In this
configuration, all HDMI ports support resolutions up to 18Gbps 4K UHD
+
(via the bypass path) while simultaneously streaming the audio and video
signal at 1080p to a USB connected PC for capture or re-broadcast. USB
capture is accomplished using the UAC (USB Audio Class) and UVC (USB
Video Class) standards, allowing the video capture component to support
most common video capture, chat, or streaming software, including the Free
OBS (Open Broadcaster Software) streaming software which is available for
Windows PC, macOS and Linux.
The video capture component of the unit is powered directly by the USB 3.0
port while the multiviewer component is powered via a DC 24V power source
and both components can be operated independently if desired. Control of
the multiviewer component is via front panel controls, WebGUI, RS-232, and
Telnet while control of the video capture component is handled by software
on the computer connected via USB 3.0.
