TS streams backup and recovery
MediaStream Stream Selector is professional multifunction software for receiving two DVB streams (main and redundant) and selecting the best one to pass further. In case of initially bit-by-bit identical input streams, smart technology uses both of them to recover missed packets and to give out recovered TS/T2MI-stream.
Software works under Microsoft Windows and low-power Intel Processors, preferably with hardware IP- or ASI- relay bypass interfaces (Silicom or Dektec-2145/2175).
Key features
- Dozens of couples of input streams are supported.
- Quality of streams is measured by basic criterions of TR 101 290.
- Input streams in each pair are allowed to be time-shifted relative to each other, optional input delay up to 10 seconds is applied.
- Bitwise-identical streams recovery allows perfectly restore original stream that is delivered in two different ways with possible losses in each one
Technical specification
- physical inputs/outputs – DVB IP Multicast/Unicast UDP/RTP, SRT, DVB ASI, DVB S/S2/T/T2/C/C2 (input only).
- input/output streams – DVB SPTS/MPTS/T2MI
- control: automatic, manual external web- and SNMP-based
- hardware relay bypasses with watch-dog timer supported: IP Silicom Ethernet interface, ASI Dektec DTA-2145, DTA-2175, Deltacast.
- Active heartbeat stream UDP-IP/RS-232, reliability statistics: 99,999% uptime.
- Configuring: manually, conf-files.
- SNMP state control
Notes and requirements
To process DVB IP streams, Intel/Broadcom chipset-based NICs are strongly recommended, particularly Silicom NICs with hardware relay bypass and watch-dog timers for reliability reasons.
To process DVB ASI, the system requires DekTec or Deltacast PCIe hardware (particularly DekTec DTA-2145/2175 are equipped with relay bypass and WD-timer).
To receive DVB-S/S2/T/T2/C/C2, system uses any Windows-compatible hardware interface.
Recommended OS: Windows 10 IoT Enterprise LTSC with certain group-policy tuning.
