Streams Delay

MediaStream Delay Server is professional software for delaying DVB-streams for a long time with high precision and optional decoding to SDI.

Software works under Microsoft Windows on x86/x64 processors, operates as a service/daemon, and is 24/7/365/N oriented. “MediaStream Delay Server” captures live input DVB-stream and stores required programs on local storage in circular buffer. At the expiration of the delay period all delayed streams are played out as original DVB- or decoded SDI-streams.

Key features

  1. Delay period is limited only by volume of local storage, can be in range from few frames till several days.
  2. When it’s possible by underlying hardware capabilities, output clock is driven and synchronized by input stream, otherwise appropriate algorithms are applied to keep delay accuracy within a few frames per each hour of delay.
  3. Fully automated software.

Technical specification

  • Physical inputs: DVB-IP Multicast/Unicast UDP/RTP with FEC, DVB-ASI/S/S2/T/T2/C/C2, HTTP, SRT. Scrambled streams are supported.
  • Outputs:

    • DVB-IP Multicast/Unicast UDP/RTP with FEC, DVB-ASI, HTTP, SRT.
    • SDI via Deltacast or Dektec or Blackmgic hardware (descrambled stream on input required), decoded from MPEG-2 (ISO 13818-2) or H.264 (ISO/IEC 14496-10) with audio MPEG-1 (ISO 11172-3, Layer I, II, III) or AAC (LC, HE-AAC v1, HE-AAC v2 according to ISO/IEC 13818-7, ISO/IEC 14496-3).

  • Correct behavior in emergency states such as power loss or signal loss, playout is guaranteed to be continued from correct point after fail is over.
  • Recognition of DTMF-sequences and SCTE-35 messages in input streams and delayed synchronous notification of external consumers by GPO or RS-232 or custom UDP or as SCTE104-over-IP client or as SNMP trap.
  • Continuous stream quality measurement of all output streams and notification of external consumers in heartbeat mode.
  • Other features
    • all known DVB-tables are bypassed.
    • active heartbeat stream UDP-IP/RS-232, reliability statistics: 99,999% uptime.
    • input stream BISS-descrambling.
    • SNMP state control
    • configuring: manually, conf-files.

Notes and requirements

To process DVB IP streams Intel/Broadcom NICs are strongly recommended.

To process DVB ASI the system requires PCIe hardware from DekTec or Deltacast.

To receive DVB-S/S2/T/T2/C/C2, system uses any Windows-compatible hardware interface (BDA).

For SDI playout, Blackmagic Decklink and Dektec devices are supported.

Recommended OS: Windows 10 IoT Enterprise LTSC with certain group-policy tuning.

Approximate resources consumption: in complicated scenarios, one simple server based on Xeon E3/Core i5 is capable to delay 4-5 typical MPTSes of 70 MBit each and decode dozens of SD-services.
