Seamless SFN switch

Reliable end-to-end SFN solution for DTT

Switches & IP transport

Upgrade your Single Frequency Network infrastructure in DVB-T/T2, ATSC3.0 and ISDB-T with a high-ranking reliable solution provided by ENENSYS’. Stay away from DTV black-out with ENENSYS’ switches providing seamless switching between your distribution links.

Highlights

Avoid TV blackout

ENENSYS' solution enables seamless switching between SFN adapters (T2 gateway, MIP inserter, broadcast gateway...), avoiding any TV blackout when errors or device failures occur in your system.

SFN network preservation with seamless switching

By using ENENSYS' seamless swictch between your distribution links of any types (satellite, microwave, IP...), any error in them is invisible for the final viewers.

Suitable for any DTT standard

ENENSYS' switches allows you to operate SFN safely for any DTT standard (DVB-T/T2, ISDB-T and ATSC3.0)

Ensure 100% service availability

With their bypass feature and their highly reliable hardware, ENENSYS' switches ensure to provide a 100% service availablity.

Synchronize head-ends on different locations

Using the unique ENENSYS' peering feature, it is possible to synchronize head-ends on different location allowing to have a high rank reliable infrastructure.

Key points

  • SFN Seamless switch-over

ENENSYS’ IP switch can resynchronizes identical streams transported over links with different propagation delays. That allows to perform seamless switching when network troubles occur, ensuring the integrity of the streams and avoiding DTV blackout.

  • 2:1 and 3:1 ASI/IP redundancy

ENENSYS’ switches manage 2:1 and 3:1 redundancy allowing to use 3 different sources as inputs of the switches. Both ASI and/or IP interfaces are supported in the most flexible solution of the market. It enables for instance to have seamless switching between 3 different network links.

  • Peering feature

Synchronize several switches of several locations using the ENENSYS’ Peering feature. It enables transmitter sites to use the same source at a given time coming, for instance, from a disaster recovery site. That allows as well to settle DTT head-end into different locations and to synchronize their outputs so that every distribution networks are fed with the same signals.

  • Specific criteria for each DTT standard

ENENSYS solution provides advanced monitoring parameters for each DTT standard allowing the operator to continuoulsy check the integrity of the data transported over its network. Relevant criteria are available for DVB-T/T2, ISDB-Tb, ATSC1.0, ATSC3.0…
