The VTX-4S module is a four port video transmitter supporting SD-SDI, SDTI or DVB-ASI signals. The VTX-4S transmits Ethernet packets to the MD8000 Switch Controller (SW-CNT) which then sends them to the appropriate trunk module and out to the wide area network. Each encapsulated Ethernet stream originating on this module is independent and can have a unique destination or multiple destinations in the network.

The VTX-4S provides robust Forward Error Correction (FEC) and Lossless/Hitless path protection switching (on the VRX-4S card) for reliable signal transport. In addition to uncompressed SDI or SDTI inputs, CBR (Constant Bit Rate) DVB-ASI signals in either byte or burst mode can be accepted by the VTX-4/s.

The front panel of the VTX-4S module features a comprehensive set of LEDs for monitoring the status and health of incoming video streams. On the rear interface card, an Active Output port is provided for signal monitoring. Using SNMP, the module is fully manageable by Media Links’ NMS systems.
