CONFIGURING STREAM SETTINGS (MANUALLY)
UNICAST MODE
The term unicast is used to describe a configuration where information is sent from one point to another point. A unicast
transmission sends IP packets to a single recipient on a network. It is possible to have multiple encoder and decoder units connected
in a system. However, in unicast mode, an encoder unit can communicate with only one decoder unit at a time (see Figure 1).
1. Access the web interface for the encoder and decoder units that will be using unicast mode.
2. Log in with
username

admin
password=admin.
3. Click the Configuration tab.
4. Set STREAM.MODE to Unicast.
5. On the decoder:
a. Set STREAM.HOST to the IP address of the encoder that the decoder is tuned in to.
b. Click Save on to save the new settings. The unit will automatically reboot. The units are now connected in unicast mode.
MULTICAST MODE
T
he term multicast is used to describe a configuration where information is sent from one or more points to a set of other points. For
example, a single encoder unit can transmit data to multiple decoder units. In addition, if multiple encoder units are used, each
encoder unit can transmit data to any decoder that is not already receiving data from another encoder unit (see Figures 2-
5).
Note: Visionary’s E/D4100 encoders default to a multicast stream address based on their host IP address. The multicast stream
address is handled in the background and does not need to be configured. If the multicast stream address needs to be known, it will be
225.2.x.x, x.x = last two octets of the encoder host IP address. Example: an encoder with a host IP address of 192.168.8.101, would have a
multicast stream address of 225.2.8.101.
1. Access the web interface for the encoder or decoder unit that will be using multicast mode.
2. Log in with
username

admin
password=admin.
3. Click the Configuration tab.
4. Set STREAM.MODE to Multicast.
5. 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.
6. 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.
STREAM BIT RATE
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.
STREAM FRAME RATE
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.
