For Digital Video Distribution, Rikei Starts to Sell ENENSYS’s “ASIIPGuard” Providing Automatic Switching between ASI and IP Signals in One Chassis

Rikei Corporation (Head Office: Shinjuku-ku, Tokyo, President & CEO: Tetsuo Kuroda, hereinafter called “Rikei”) would like to announce that it has started to sell new ASI switch “ASIIPGuard” manufactured by ENENSYS Technologies (Head Office: France, President & CEO: Régis LE ROUX).

Nowadays, in addition to traditional DVB-ASI*1), a widely used interface designed to carry digital video content, IP distribution is becoming more and more common with an increasing speed of IP networks. Therefore, when operators and broadcasters install new distribution facilities, equipment such as transmitters and interface converters are often required for both ASI and IP, causing great concern about the initial investment costs and configurations.

The new “ASIIPGuard” provides switching capabilities between devices and networks in one chassis without the need for the user to care about ASI or IP.


ASIIPGuard not only supports widely-used traditional DVB-ASI, but is also equipped with ASI and IP interfaces on both input and output sides, enabling flexible switching between ASI and IP. In addition, when errors are detected, ASIIPGuard seamlessly switches from the faulty input to the valid input.ASIIPGuard also makes it possible to shave off any extra investment costs.


  • Supporting up to six switching modules
  • Switching between DVB-ASI and IP
  • 2:1 or 3:1 automatic switch redundancy
  • ProMPEG CoP#3*2) supported
  • ETR290*3)–based error detection
  • Full SNMP v2*4) supported
  • Flexible switching conditions*5) configuration
  • Real-time monitoring feature
  • Easy-to-use GUI

*4 Full SNMP v2: Protocol for monitoring and managing devices such as routers, computers, and terminals on TCP/IP networks.
