== Use the polycom (H323 device) system to connect to a Vidyo meeting ==

The only polycom system compatible with Vidyo is available **in the LPSC room 300A**.


To connect to a Vidyo meeting :
 - switch the TV on,
 - on the TV choose the source "component",
 - switch on the Polycom,
 - to connect to a Room via the polycom system, you need to call the following:
     {{{3{meeting_extension}@137.138.248.227 }}} or {{{ 3{meeting_extension}*{PIN}@137.138.248.227}}}
     if the meeting has a PIN,
 - for example to connect to a meeting with the extension 987654 and the pin 1234 one should call: 3987654*1234@137.138.248.227


==== Hints ==== 
- "137.138.248.227" is one CERN vidyo gateway address. You can choose another one according to the addresses given at: [http://information-technology.web.cern.ch/services/fe/vidyo/howto/users-use-h323sip-client-connect-vidyo-meeting CERN help]
- To type "@", use the virtual keyboard of the polycom remote control (a small keyboard is drawn on a key on the left hand side of the remote).


== Use your PC to connect to a Vidyo meeting ==
(tested with Windows and MAC OS)

=== Before you start: Vidyo configurations ===

This should be done before you connect to Vidyo for the first time.

- unlike EVO, you have to '''download''' and '''install the Vidyo software''' on your PC; 
  - to do so, open your web browser and direct it to the CERN portal:   [https://vidyoportal.cern.ch/] 
  - or any other portal you may be required to go to in the case of a special event; 
  - Vidyo is free of charge.

- start the Vidyo application
- enter the Vidyodesktop (to do so: use the third button of the mouse on the logo of the Vidyo application);
- click on "Configurations"
- click on the "Network" menu:
  - in the window "Vidyo Proxy", select '''"Always use Vidyo Proxy"''' and "Vidyo Proxy Adress: Automatic"
  - make sute that "Home server" is set to "vidyoportal.cern.ch;
  - click on "Apply" and "Save" (not mandatory for Windows).
- click on the "Devices" menu:
  - select the option '''"Echo Cancellation"''';
  - click on "Apply" and "Save" (not mandatory for Windows).
  - Please note: this parameter is also accessible while running a meeting by clicking on the Wheel Symbol at the right of the upper menu.


=== Connect to a meeting ===

- open your web browser and direct it to the '''CERN portal''': [https://vidyoportal.cern.ch/]
- connect with your CERN username and password (or any special username/password, e.g. for a given conference or a school)
- you should then either:
 - '''join a given conference room''':
   - simply enter the room name in the given field, and click on "Join Room".
 - '''create a chat''': 
   - join your own room (a Vidyo window appears);
   - in the original web page, select "Control Meeting" (at the upper right side);
   - click on the "Add Participant" logo (a green icon representing a person with a white "+" sign on top);
   - and then simply '''add the name''' of the person you want to invite to your room ("Catherine Biscarat" for example).


=== Useful Options ===

- list names of all participants on the Vidyo Screen: click on wheel - options - show participant names - apply - save

=== How to add a polycom (**only used in specific cases**)===

When you connect your PC to a meeting and you add the polycom system, people in the meeting can not see the LPSC room through the polycom **unless** the main meeting room connect the polycom from outside; this method is rarely used (for the masterclass for example), it would be impossible for meetings like regular ATLAS meeting; in this case, please use the polycom system directly to connect the meeting. 

- connect to a meeting with your PC as usual;
- then select the "control meeting" menu and click on the "add a participant" logo (a green icon representing a person with a white "+" sign on top);
- enter the IP address (with a 21 in front of the IP) or the room name (only possible if the room is already registred in the CERN system); at the LPSC this means:
   - '''petite salle du conseil''': 21134.158.40.50
   - ''' salle 300 A''': 21134.158.40.52 or ROOM_IN2P3_GRENOBLE;
- in order to use the camera of the videoconferencing system, simply switch off the camera of your PC (camera logo in the upper menu of the Vidyo window).
- when your meeting is over, remember to disconnect the videoconference system.
