In partnership with the EBU, Cisco and OpenHeadend, the Upipe team has created a web browser plug-in allowing to receive multicast streams in a unicast-only network, using Automatic Multicast Tunneling. The plug-in is now available online, and by default connects to a Cisco router hosted at the EBU, with a number of multicast streams provided by OpenHeadend playout.
Note that the plug-in only works on Native Client-enabled browsers (eg. Google Chrome).
