Benefits

  • SFN Seamless Switch-over

ENENSYS’ IP switch can resynchronizes identical streams transported over links with different propagation delays. This allows for seamless switching when network troubles occurs, ensuring the integrity of the streams and avoiding DTV blackouts.

  • 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, making it the most flexible solution on the market. It enables, for example, seamless switching between 3 different network links.

  • Peering Feature

Synchronize several switches in several locations using the ENENSYS’ Peering feature. It enables transmitter sites to use the same source at a given time, when coming from, for instance, a disaster recovery site. This allows for, in addition, to settle DTT head-end into different locations and to synchronize their outputs so that every distribution network 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 continuously check the integrity of the data transported over its network. Relevant criteria are available for DVB-T/T2, ISDB-Tb, ATSC1.0, ATSC3.0, etc.
