The VRX-4S (2022) module is a four port video receiver supporting SD-SDI, SDTI or DVB-ASI signals. As a receiver, the VRX-4S (2022) accepts Ethernet packets from the MD8000 Switch Controller (SW-CNT) and sends them to the appropriate video output ports. The four Ethernet streams that terminate on this module can originate anywhere in the MD8000 network. Each output port has the same functionality as a VIF-1Sch module.
The VRX-4S (2022) provides robust Forward Error Correction (FEC) and Lossless/Hitless path protection switching for reliable signal transport. DVB-ASI output signals are reconstructed from the transparent Ethernet transport of MPEG2TS. Nulls within the ASI wrapper are re-inserted matching the original DVB-ASI signal. Only CBR (Constant Bit Rate) is supported for the MPEG2 DVB-ASI transport stream.
The front panel of the VRX-4S (2022) module features a comprehensive set of LEDs for monitoring the status and health of incoming video streams. Using SNMP, the module is also fully manageable by Media Links’ NMS systems.
