The 2wcom FlexNsert+ DAB+ Distribution Inserter receives a DAB ETI data stream (according to EN 300799) or a DAB EDI data stream (according to TS 102 693). The FlexNsert+ DAB+ converts the data stream into a standard MPEG2-TS-signal and outputs it via its transport stream interfaces (IP/ASI).

Additionally, the FlexNsert+ may act as timestamp Inserter for SFN Networks. The generation of timestamps within the MPEG-stream is basis for a synchronised transmission at transmitter sites.

Data input

• ETI: Standardized input stream from a DAB/DAB+/T-DMB multiplexer over a standardized 2Mbit link (E1).
• EDI (optional): EDI performs data transmission via global IP network (ETI via IP). In contrast to ETI, there is no need for a dedicated line.

Transport stream output

• ASI
• Ethernet (ETI-TS)
  • Pro-MPEG FEC Practice #3 release 2
• Ethernet (EDI)
  • Reed Solomon EDI-FEC, level 0-5 recommended (TS 102 821)
  • Dual streaming (optional)
  • Data spreading (optional)

Monitoring and Control

• via web-based GUI
• via Satellite In-Band Remote Control (SIRC)
  (e.g. changing configuration, firmware update, relay switching)
• via SNMPv2c and relay (ETI/EDI parameters)

Conditional Access Decryption

• On request

Advanced functions

• 2wcom FlexOptimized Bandwidth Saving Technology (optional) – saving up to 45% of bandwidth
• 2wcom FlexRegio Multiprogram Regionalisation Management (optional)
• Timestamp generation for SFN Networks
