MIPDVB for HDc

DVB-T SFN Adapter

MIPDVB for HDc is ENENSYS’ SFN adapter module for DVB-T that inserts MIP packet, performs bit rate adaptation and PCR restamping to enable Single Frequency Network broadcasting over DVB-T networks.

Applications

  • DVB-T SFN broadcasting
  • DVB-T2 ready

Highlights

SFN Management

The ENENSYS SFN Adapter provides synchronization (timestamp) information to all DVB-T transmitters to generate the same data at the very same time over the same frequency. It can also control individually each DVB-T transmitter to set remotely frequency offset or time offset information.

1+1 seamless redundancy - SFNguard

ENENSYS' patented technology, SFNguard, is the unique 1+1 redundancy mechanism that guarantees a seamless switch-over in SFN to avoid any TV black-out during change-over operation between 1+1 MIP inserter. Combined with ENENSYS seamless ASI switch, ASIIPGuard or the ENENSYS seamless IP switch, IPGuard, it offers a unique solution to maintain DVB-T transmission after MIP inserter change-over upon input failure or product maintenance.

T2 ready

The MIPDVB is running in a new generation platform to provide higher density, to operate with other ENENSYS module in the same chassis and to provide high reliability features with redundant power supplies. The product can migrate to a DVB-T2 Gateway (T2Gateway for HDc) without changing the hardware by only a firmware update.

Dense solution

Operating at the head-end after DVB multiplexer, the MIPDVB for HDc runs in the HDc chassis to embed up to 6x MIPDVB modules in 1U so that the same chassis can output up to 6 TS with MIP packets over ASI or IP.

MIP inserter with IP inputs/outputs

The MIPDVB receives at the input a MPEG-2 TS over ASI or IP, inserts MIP packet to synchronize all the DVB-T transmitters to broadcast the DVB-T. multiplex over Single Frequency Networks and performs bit rate adaptation and PCR restamping to match with DVB-T transmission parameters. It outputs the new MPEG-2 TS with MIP packet over ASI or IP. It can support redundant IP inputs and mirrored IP outputs throughout 4x gigabit Ethernet interface.

Key points

  • MIP insertion according to ETSI EN 101 191
  • Unique seamless switch-over, SFNguard
  • Redundant inputs and mirrored outputs over ASI or IP
  • PCR restamping and bitrate adaptation
  • Straight integration into any NMS: full SNMP v2  compliant
  • Upgradable to DVB-T2 Gateway
