Each VNC 325 codec has an integrated web interface. One codec in the VN-Matrix system must be designated as the system controller, and the controller can be any unit in the system, whether it is configured as an encoder or decoder. All normal system configuration and control is via the web interface of the designated controller. Using a computer on the ® ® same network and a standard web browser, such as Mozilla Firefox or Microsoft® Internet Explorer®, you can configure any VNC 325 unit in

Highly efficient compression algorithms — The VN-Matrix 325 system uses a minimal amount of data to transport video and audio across the network. NOTE: It is crucial to the effective operation of VN-Matrix 325 that sufficient data throughput be achieved, especially where multiple sources are encoded. The network efficiency is directly affected by the speed and configuration of each element, such as switchers and routers, within its infrastructure. The VN-Matrix 325 system achieves optimum t

Data Transport Methods Source (video) data from a VNC 325 encoder can be distributed to multiple decoders and displays (one-to-many) or to a single decoder and display (point-to-point). Video data is transported from the source (encoder) to the display (decoder) using one of three methods, in order of preference, which are detailed in the following sections: • Multicast real-time protocol (RTP) — Best choice • Unicast RTP — Second choice • Unicast Transport Control Protocol (TCP) — Acceptable

This is the recommended transport method for real time video and audio data over an IP network. However, because RTP is a connection-less protocol, data delivery is not guaranteed. Where data packets are lost (such as due to excessive network traffic), the PURE3 algorithm carefully manages the data stream to minimize any image disruption. NOTE: In figure 3, IP decoder 3 is designated as the system controller. Unicast RTP Like multicast RTP, the unicast RTP data transport method uses a real-t

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 ineffic
