Unicast TCP

The unicast TCP data transport method uses standard TCP protocol and should be used for single point-to-point transfer of data only. This method is connected as shown in figure 5.

NOTES: Multiple decoder connections are theoretically possible using this method

but not recommended. Each additional connection creates extra loading on the encoder CPU, which ultimately results in poor display performance. In

addition, multiple TCP streams carrying the same source data is an inefficient use of network bandwidth.

While figure 5 shows two decoders, in the scenario shown only IP decoder 1 is set to actively decode data that is streamed to it. IP decoder 2 may be

in standby (set as Device Type: None, see “Configure Encoders or Decoders“) or may be receiving streamed data from another encoder.

In figure 5, IP decoder 2 is designated as the system controller.

TCP is a connection-based protocol. Data is guaranteed to be delivered, however excessive network traffic, which impacts real-time performance, may delay delivery.

Data and Control Routing

The system can be used over both switched (single segment) and routed (multisegment) networks

The VN-Matrix 325 system can be configured to run using either a single LAN port (1 or 2) or both LAN ports. In the single port configuration, all data (image, audio, control, and monitoring) is transported on the designated port. In the dual port configuration, image and audio data is transported on one connection while the other LAN port is used for monitoring and or management functions.

All system control is managed by the VNC 325 that has been designated as the controller. Any changes made in the network browser are sent to the affected codec from the controller via the network that has been assigned for streaming. The browser is accessible via either network port on the unit that is configured as the controller.

Video and audio data can be transported over either of the LAN ports on the VNC 325 and are independent of the system control data.
