Visionary Solutions 4K UHD over IP cinema quality, ultra-low latency [~1 frame - visually lossless] encoder and decoder bypass
the constraints of traditional switch matrix distribution systems by harnessing the flexibility and scalability of converged IP
networks.
With the growing demand for 4K UHD video, professional AV designers and IT directors–in an increasingly converged AV/IT
environment–can use Visionary Solutions products as an alternative to conventional distribution systems.
Visionary’s PackeTV® and PacketAV® products can be deployed on any industry standard IP network. They can be used on
existing enterprise IP networks or on a physically separate parallel network [private network] to offload traffic, using the same
network protocols, methods, and devices but without intermingling video traffic with data or voice, and with equal ease of
installation.
Visionary’s MV4 is a high-performance IP Multiviewer with integrated scaling and multi-windowing technology. The MV4 IP
Multiviewer is a 1RU rack-mountable windowing appliance that connects to a network and accepts up to (4) AV over IP
streams from PacketAV Matrix Series ultra-low latency 4K encoders. The MV4 is designed for processing these dynamically
switchable input streams simultaneously in a variety of layouts. Each input can be scaled and positioned according to default
presets (such as quad view, side-by-side, Full, PiP, PaP, 3+1, etc.) or in any user-defined configuration. With the MV4 users can
mix and match input resolutions, scale any video input up to 4K UHD and route any input to any window, combining up to
four sources together into a single 4K image. The combined output video is then encoded into a single stream sent to one or
more PacketAV Matrix Series Decoders at resolutions up to 4K. Multiple MV4’s can be cascaded to provide 7×1, 10×1, 13×1,
16x1 or higher capability.
The MV4 IP Multiviewer enables users to select audio from any of the four sources for playback — even one not currently
displayed. Seamless switching ensures no frame loss during window and video transitions. Both 1080p60 (HD) and 4K (UHD)
inputs can be displayed without downscaling, taking full advantage of the MV4 IP Multiviewer’s remarkable image processing.
MV4 presents a paradigm shift in traditional multiwindowing technology that has until now required a separate HDMI
multiviewer at each display. This flexible and scalable method of IP distributed multi-windowing allows the MV4 to be
centrally located mounted in an MDF rack or anywhere else on the network, expanding capabilities while reducing installation
and maintenance costs.
The MV4 IP Multiviewer is controllable via the front panel buttons along with an intuitive on-screen (OSD) Graphical User
Interface, simplifying system configuration. Third-party control is supported via API. Visionary’s MV4 IP Multiviewer is an ideal
solution for small and large commercial venues that require monitoring or displaying of multiple sources simultaneously.
From the conference room to the control room, to the classroom, the versatile MV4 represents the next evolution in IP
Multiviewer technology.
An encoder is connected to an [HDMI] AV source signal [a camera, STB, media player, PC or server, BluRay player, or digital
signage player, etc.]. The signal is converted into a packetized network stream that is compatible with off-the-shelf IGMP
enabled Gigabit Ethernet (GbE) switches (Jumbo Frames enabled). Using an existing CAT 5/6 infrastructure, users can connect
CAT 5/6 to any MV4 IP Multiviewer anywhere on the same GbE network. The MV4 decoders take the IP packets received over CAT
5/6 cables, same as other Visionary Packet AV decoders, and sends them to the MV4 encoder to be converted into a packetized
network stream that is received by a Packet AV decoder. The decoder then converts them back into an HDMI signal
connecting directly to a display, delivering visually lossless video. A signal from any encoder can be sent to any decoder on the
same network. The signals can easily be controlled with our Vision Lite software to create different outputs on the display side,
including video wall or matrix switching.
