TNS541 Seamless TS Monitoring Switch

SKU: TNS541 Seamless TS Monitoring Switch

TNS541 Seamless TS Monitoring Switch


Product Description

The TNS541 is an ideal solution for intelligent 1+1 redundancy switchover between two MPEG transport streams. It improves the robustness of the system with dual power supply and seamless switchover with no interruption to the transport stream.

The TNS541 ensures more reliable and robust delivery of video as it continuously monitors health status of the incoming signals and switches over if errors are detected. Delay differences are handled by matching and alignment of packets and switchover is based on highly configurable switching criteria.

The TNS541 is also capable of performing synchronized and seamless switchover between two different SFN streams or T2MI streams in such a way that modulators remains synchronized.

The TNS541 is part of T-VIPS’ nSure product line which is designed to ensure the delivery of high-quality video content. The nSure product line simplifies the monitoring, analysis and switching of transport streams and services throughout video broadcast networks.



• All systems requiring intelligent 1+1 switchover between two MPEG transport streams.

• Seamless switchover in DVB-T/T2 SFN networks


Key Features

• Seamless TS switchover

- Switches between two non-identical input streams at the TS packet boundary without loss of sync in downstream equipment

- Delay alignment of two identical transport streams provides seamless switching of Transport Stream content

- Two DVB ASI inputs and 1 main ASI output

- Two additional configurable ASI outputs

- Fully configurable switching criteria

• Frame aligned seamless switchover

- Alignment and seamless switchover between SFN streams from two T-VIPS CP511 SFN Adapters with preservation of MIP packets.

- Alignment and seamless switchover between T2MI streams from two T-VIPS CP560 DVB-T2 Gateways with preservation of T2 time stamps.

• Robustness and flexibility

- Dual power supply

- One or two switch modules in 1RU 19” (option)

- Relay protected main output ensures signal through even in the event of power loss or power supply failure

• Transport Stream monitoring and error detection

- Simultaneous monitoring of two MPEG transport streams

- Full support for ETR 101 290 alarm conditions (Priority 1/2/3)

- PSIP related alarms from ATSC A/78

- Minimum and maximum PID rate monitoring

• User-friendly configuration and control

- WEB/XML based remote control

- SNMP agent for easy integration with NMS systems

- Integrated with T-VIPS Connect
