Advanced Configuration
1. Access the web interface for the encoder or decoder unit that will be using multicast mode.
2. Log in with

=admin.
3. Click the
Configuration
tab.
4. Set
STREAM.MODE
to
Multicast
.
5. On the encoder:
a. Click
Save
to save the new settings. The unit will automatically reboot.
6. On the decoder:
a. Set
STREAM.HOST
to the IP address of the encoder that the decoder is tuned in to.
b. Click
Save
to save the new settings. The unit will automatically reboot.
7. Repeat steps 1–4 and step 6 for each decoder you want to tune into the encoder’s multicast stream.
The units are now connected in multicast mode.

The bit rate (
STREAM.BIT_RATE)
defaults to
auto
. This means that the encoder will choose the optimal bit rate for the input
resolution and content. This can range up to a maximum of 850Mbps for highly complex 4K video. If you are trying to limit
bandwidth used, you can set this to 200Mbps (this gives excellent 1080P60) down to 50Mbps. You can experiment with your normal
content and see what bit rate setting is best for your use case, or just leave this in
auto
if you are not limited on bandwidth between
switches.

The frame rate (
STREAM.FRAME_RATE
) of the incoming video may be reduced to allow higher resolutions at lower bandwidth. For
instance, you might have 1080P60 content that is of slow-moving scenes or other less complex video. You could then use the 50%
setting to lower the frame rate to 30fps. You could also set the stream bit rate to a lower value to make sure that the stream only
uses that amount of bandwidth.

Below are some options for decreasing switch time (faster switching):
1. Set the decoders to scale the HDMI output for the monitor resolution. This is the VIDEO.FORMAT value on the config.html page.
If the decoders are set to VIDEO.FORMAT=SOURCE then switching time can be longer due to changes in format.
2. All of the sources must have the same resolution and refresh rate. Ensure that the encoders’ input format matches the formats
of the monitors connected to the decoders. Make sure that all encoders are using VIDEO.HDCP_FORCE_ON, or that all sources
are the same (HDCP on or off but not a mix).

When connecting USB devices to encoders and decoders, the function is similar to that of a video matrix. Connecting a computer to an
encoder unit and a Human Interface Device (HID) device to a decoder unit allows you to control the computer from the decoder unit.
USB over IP enables non-isochronous USB devices to be used remotely. USB over IP is enabled by default.
There are three USB modes available: Auto Select, Active per Request, and Active on Link.
