Videoconferencing background: EVO/SeeVogh

Enabling Virtual Organizations or EVO provides a means of videoconferencing that -in principle- is completely separate from our "standard" Ad-Hoc H.323 conferencing. It is the successor of the (now defunct) VRVS system. It is largely desktop based, has a fairly large user community, and the recommendation for e.g. the LHC experiments (see the CERN RTAG-12 working group) is for EVO to be always available as a means of communication. Moreover, it is Java-based, and is (freely) available on multiple platforms (Windows, Linux, ...), so for smaller-scale meetings (but see the notes on meeting etiquette) it may be a good low-budget alternative.

EVO is very flexible, in that it supports multiple protocols:

Also several telephone bridges are available.

Videoconferencing background: Vidyo

For those working on an LHC experiment, Vidyo is also a good option to connect to D0 meetings.
1) Start your Vidyo client
2) Log into the cern video portal
3) In the address box of your Vidyo client, simply enter (eg. Then click "Call Direct" to connect ESNET.

If you want remote collborators to connect to your Vidyo meeting with their Polycom/h323 client, see the instructions Vidyo page.
