ASIIPGuard - Seamless ASI switch


ASIIPGuard is ENENSYS Innovative and dense ASI switch that enables automatic 2:1 or 3:1 switch redundancy of ASI and IP feeds. It can provide seamless switching capabilities of identical MPEG-2 TS or T2-MI streams

ASIIPGuard ASI and IP

ASIIPGuard aims at providing automatic redundancy switch between two or three MPEG-2 Transport Streams according to the validity of the incoming streams. Upon ETR290 errors, SFN errors, T2-MI errors or advanced MPEG-2 TS errors, ASIIPGuard switches automatically from the faulty input to the valid input.

Additionally, the ASIIPGuard can supports up to 6 switch functions in the same chassis providing 6 ASI switches in 1RU. As an option, it can switch over ASI and IP feeds and outputs the selected input over ASI and IP.

The ASIIPGuard strives to provide a true seamless switch-over under the following conditions:

• In DVB-T Single Frequency Networks, the ASIIPGuard enables a unique, automatic and secured SFN seamless change-over between two ENENSYS SFN Adapter, This is mandatory to guarantee SFN broadcasting, where all DVB-T SFN transmitters must receive the same content to transmit it over the same frequency at the very same time.

• In DVB-T2, the ASIIPGuard can seamlessly switch-over redundant T2-MI streams. It can provide an automatic 1+1 redundancy mechanism between two DVB-T2 Gateways. The ASIIPGuard offers a safe and seamless redundancy solution for SFN and MFN DVB-T2 broadcasting.

• MPEG-2 Transport Streams can be carried over redundant links. Both links may have different delays (satellite-IP, IP-IP). The ASIIPGuard enables to realign both streams to seamlessly and automatically switch from ASI or IP input to ASI or IP input.
