VTX-4S – 4 Port SD/SDTI/DVB-ASI Video Module
VTX-4S – 4 Port SD/SDTI/DVBASI Video Module
The VTX-4S module is a four port video
transmitter supporting SD-SDI, SDTI or
DVB-ASI signals.
KEY FUNCTIONS:
• External interface to SD/SDTI/DVB-ASI
user circuit
• Internal electrical interface to MD8000
SW-CNT modules
KEY FEATURES:
• Accepts 1-4 input signals
• Front Panel LED indicators for all four
inputs
• SD-SDI input: 525i (59.94Hz), 625i
(50Hz), SMPTE 259M. Can carry up to 8
audio channels
• SDTI: SMPTE 305M
• DVB- ASI: MPEG2-TS, operates in byte
or burst mode
• Granular bandwidth allocation
• Forward Error Correction (FEC)
• Active Output monitor
• Four 75 ohm electrical inputs, BNC
connectors
• Selectable VLAN priority
• Selectable ASI bandwidth: 5Mbps to
270Mbps
The VTX-4S module is a four port video transmitter supporting SDSDI, 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.
