1.4 System Connections
Video Server operates as one of two modes; Encoder or Decoder. Video Server
Systems can be connected in either 1-to-1 where one encoder is connected to one
decoder or 1-to-multiple where one encoder connected to many decoders.
The following chart shows status of video, audio and serial data on each mode:
System Mode Video Audio Serial Data
Encoder Transmit Transmit/Receive Transmit/Receive
Decoder Receive Transmit/Receive Transmit/Receive
Therefore, the system modes are defined by the video communication and all system
modes are capable of bi-directional transmission of audio or serial data.
Topology
Generally, the Encoder and Decoder are connected in 1-to-1 mode. To support
specific situation, 1-to-multiple connection is also supported.
 1:1 Connection (Unidirectional Transmission)
The most commonly used configuration is 1-to-1 connection. An Encoder is installed
at a site where video images can be transmitted and a Decoder is installed at a center
location to receive and view the video images on monitors. Audio and Serial data are
transferred in either direction. An Encoder and Decoder can be connected by setting
the Encoder’s Address for the Decoder’s Remote IP.
