6.0 Working
6.1 Architecture
VERSA-4K uses Client-Server architecture, where each function such as Video, Audio,
USB, IR, and RS-232 is considered as a service. VERSA-4K-S (Sender) acts as a server,
and provides services independently under one Group ID. Each VERSA-4K-R
(Receiver) in the network acts a client and receives a service by joining in the group
using Group ID.
A Receiver should have the same Group ID as sender to receive a service. Among all
the services only USB 2.0 is mutually exclusive, means, only one receiver in a group
can exclusively connect to the sender and exports all the USB2.0 attached to it. See
USB over IP for more Details.
Unicast Mode vs. Multicast Mode
Unicast is used in One-to-One Applications, where only one receiver is allowed in a
group. Unicast offers simple and secure ways to extend Video and USB applications
to only one receiver.
Unlike Unicast Mode, Multicast mode is used in One-to-Many Applications, where
multiple receivers are allowed in a group and request services from a sender.
Multicast gives true flexibility to scale the system. Also, enabling Independent
Routing on the receiver allows choose and various services from multiples Sender in
different groups.
Fig 9: Unicast and Multicast Mode

14
6.2 General Settings
Device Name
User can assign custom Device Name to VERSA, which can be used to identify its
Location or Purpose. Device Names are useful for Logical representation of the
system in big installations. Device Names are not linked to IP address, these are only
used as identifiers for the User. For instance, all the Receivers connected to the
projectors in a school can have Room Number as Device Name. By default, the Device
Name is set to "VERSA" for both sender and Receiver.
Group ID
In VERSA's architecture, each service from a Sender is served on Multicast IP. Group
ID is a simpler representation of Multicast IP. Each Sender needs to have a unique
Group ID on the network. A Group ID Ranges from 0000 to 9999, which allows scaling
the system up to 10,000 Senders in one network. A Receiver can receive a service
from a sender by having the same Group ID. In multicast mode multiple Receivers can
join in the same group, and can multiplex various services from Senders in different
groups, which is also called as Independent Routing.
6.3 Auto IP
Auto IP, is also called as Automatic Private IP Addressing (APIPA) is a method where
an IP device on a network selects an unique IP address in the absence of a DHCP
Server. An Auto IP device, such as VERSA holds an IP address in the range of
169.254.x.y in Auto IP Mode, where : x,y can range from 0 to 255.
By default, Auto IP is enabled in VERSA. To access the device WEB-GUI or to control
the device with PC-GUI, the User's PC should be in the following network:
IP Address
169.254.x.y
Where:
x = 0 - 255
y = 0 -255
Subnet
255.255.0.0
6.4 Independent Routing
Independent Routing is featured in the VERSA-4K-R (Receiver), which allows
multiplexing different services from multiple Senders. For example, a Receiver can
receive video form Group-1, Audio from Group-2 and USB from Group-3 as shown
below.

15
Fig 10. Independent Routing
Note: Audio only works when there is an active Video Group.
6.5 Video Over IP
VERSA-4K-S uses visually lossless compression to encode 4K Video. Along with bit
rate and Frame rate adjustments, Sender provides Various Quality modes and Bit
Rate adjustments to minimize the network bandwidth.
Encoder Settings
Bit Rate
Best Effort
VERSA takes complete freedom to deliver best
quality content with less compression. A typical
1080@60 video can take up to 200Mbps bandwidth
10 - 200Mbps
This forces the encoder to compress more to meet
the selected video bandwidth requirement
Frame Rate
0 - 100%
Can be used to minimize the bandwidth by
reducing the number of frames that needs to be
encoded. Low frame rates can be used for Static
Image Videos
Quality Mode
Video Mode
More priority to Frame Rate over Video Quality
Graphic Mode
More priority to Video Quality over Frame Rate.
Some of the frames might be dropped. This mode
is typically used for Static Image Videos.
1 -5
The higher the value, lower the Video quality
Anti-Dither Mode
ON/OFF
Anti-Dither Mode removes the noise in the source
video by averaging them with surrounding pixel
data. Don't enable this if the source video is clean
EDID Management
VERSA-4K Sender can save up to two EDIDs. One of them is Default EDID, which
cannot be modified and other one is a Custom EIDD, which can be updated from
Receiver end. Sender always serves Custom EDID to the source in the absence of
Custom EDID it serves Default EDID.

16
In multicast mode, a receiver in the group can send an EDID Update Request to
replace Custom EIDD with its attached Sink EDID. A Receiver automatically sends an
Update Request when Display is detected, if "Use this EDID" option is enabled. When
multiple receivers send an EDID update request, the last received EDID will be used. In
multicast scenario it is recommended to enabled "Use This EDID" option on only one
receiver.
Fig 11. EDID Management
6.6 Video Scaler
Receiver (VERSA-4K-R) has built-in Video Scaler. The Scaler supports Up-scaling (Low
resolution to High Resolution), Down-Scaling (High Resolution to low resolution) and
Timing Conversion (Interlaced to Progressive and vice versa). See HDMI Video
resolution support list for more information.
The Scaler can be set to "EDID Preferred", which will automatically scale the input
video to the native resolution of the monitor as defined in its EDID. This feature
provides the flexibility to use different kinds of monitors at the Receiver end
regardless of brand and 4K resolution support.

6.7 Video Wall
VERSA receiver has built-in Video Wall support with Bezel and GAP compensation,
Pixel Wise panning, Image Rotation and Mirroring. The Video Wall layout is a
rectangular array of monitors, where the position (x', y') of a monitor on the Wall is
identified with row and column number. The total number of rows indicates Vertical
Monitor Count (Y) and the total number of columns indicates Horizontal Monitor
Count (X).

17
Fig 12. Video Wall Layout
For example, to build a 2x2 (two by two) Video Wall, which has 2 rows and 2 columns.
The Horizontal Monitor Count [X] = 2, and Vertical monitor Count [Y] =2
A total of 4 Receivers are required to build this wall and they can be positioned at:
(0,0) , (0,1) , (1,0), and (1,1)
Each Receiver includes a Video Wall Preview in its WEB-GUI, which helps to visualize
the wall. From the above example to the place a receiver in Top left corner of the
video wall, set the Wall Size = 2x2, and select the position (0,0) as shown below.

6.9 Audio Over IP
VERSA Supports up to 7.1ch HDMI Audio (See HDMI Audio Format Support List for
more details). The Sender also supports HDMI audio embedding from LIN IN, which is
used for VGA sources. Bidirectional audio pass-through is only available in Unicast
Mode, which make it ideal solution for Remote PC extension.
Fig 15. Bidirectional Audio Pass-through
In multicast Mode, Sender supports 3 Input Modes to select an audio source between
HDMI Audio and LIN IN Audio. The selected audio source is embedded into the video
and multicast to all the Receivers in the group. Also, Receiver supports 3 Output
Modes to route audio between LINE OUT and HDMI OUT. See Audio Modes for more
details.
Note:

20
1. While using Independent Routing, receiver must be a part of a working video
group to output the audio.
2. Bidirectional Audio Pass-through is only supported in Unicast Mode and
when LINE IN is selected.

6.10 Keyboard and Mouse Over IP
Keyboard and mouse connected at the receiver end operates differently compared to
other USB2.0 devices. To have instant accesses to the PC, both keyboard and mouse
are always emulated by the Sender and only key and mouse parameters are received
from each Receiver. As result, no explicit connection or driver installation is needed.
In multicast mode, a PC can be controlled using mouse and keyboard from any
receiver in the group. Each receiver has dedicated keyboard and mouse ports to use
feature.
