The standard platform for oral proceedings held by videoconference (VICO) is Zoom.
Please make sure that your internet connection is strong and stable. Using an Ethernet cable instead of Wi-Fi helps avoid sudden drop-outs, allowing the oral proceedings to run smoothly.
Always use "join with computer audio" when joining a Zoom meeting and check that you have selected the correct device in the Zoom audio settings.
If two or more people who are physically present in the same room intend to speak during the proceedings, they should each use their own individual audio and video equipment to connect to the proceedings.
Please use a high-quality microphone, namely a USB headset with integrated microphone or a unidirectional USB "podcast" microphone (clip-on or stand-alone) with a frequency response of at least 125 Hz to 15 000 Hz and an echo-cancelling function.
Please use audio devices that are connected to the computer by USB cable. Devices connected to the computer using Bluetooth are only acceptable if an additional Bluetooth USB connector is used, and if the participant is alone in the room to avoid interference.
For VICOs involving interpreting in particular it is not recommended to use microphones built into a PC or a webcam, wireless headsets connected to the computer via its built-in Bluetooth, phone earbuds (even if wired) or standard VICO room equipment with omnidirectional microphones, which are often shared. None of these perform adequately for remote interpreting. They do not cover the frequency range of 125 Hz to 15 000 Hz that simultaneous interpreters need in order to be able to listen and speak at the same time, as stipulated in ISO standard 24019:2022.
Please do not use external speakers as these can cause echoes. We recommend using a headset or headphones.
Microphones, speakers and cameras - dos and dont's
Choose a quiet location to connect to the Zoom meeting. Generally speaking, a smaller space with soft furnishings improves your acoustics and minimises reverberation.
To prevent resource issues, we recommend that you use a powerful computer running a recent Windows or Macintosh operating system. The same applies to your mobile device if you want to use the Zoom mobile app for iOS or Android. Please note that mobile devices are not recommended if you intend to speak or listen to the interpretation provided.
We recommend using a good-quality webcam (HD 720p or above) positioned to provide a close-up head shot of the speaker. Most importantly, each person should have their own camera.
Parties who are attending oral proceedings are strongly advised to arrange a test call before the date of the oral proceedings. This should be done in good time (preferably two to three weeks – but at least five working days – beforehand), but not more than a month in advance, because of potential software updates. Needless to say, the test call should be carried out from the location and with the equipment that will actually be used by the party during the proceedings.
To arrange a test call with us, please send an email to EPOvicotest@epo.org and include your preferred date, your application number and the name and contact details (phone number and email address) of each participant. We will then schedule a 30-minute test session (available Mondays to Fridays between 08.30 and 18.00 CET) and send you an invitation with the connection details for the call.
The test will be an opportunity to check that:
- The VICO application works properly
- The connection is stable and both audio and video are of adequate quality
- It is possible for both sides to present content
- Access to multiple voice channels is available for simultaneous interpreting.
Should you experience any issues in establishing the connection, please contact the EPO videoconferencing service on: (+31) (0) 70 340 4444.
Users involved in oral proceedings on Zoom are invited to familiarise themselves with the following technical requirements and recommendations.
Supported systems for Zoom
For oral proceedings held by Zoom, the EPO supports the following technologies:
- Zoom desktop client installed on Windows or Mac (regularly updated to the latest version)
- Zoom mobile app for iOS or Android (regularly updated to the latest version)
- Zoom web client (Chrome, Firefox, Edge, Safari: within two versions of the current version) for oral proceedings in opposition. As oral proceedings in examination held by Zoom are end-to-end encrypted, the Zoom web client is not suitable for oral proceedings in examination.
Regardless of which Zoom set-up you have, you are advised to run a compatibility test of your equipment with the EPO, preferably at least five working days before the oral proceedings are due to take place (see "Test call" above).
