The CERN Webcast Service opens CERN lectures, meetings and seminars to universities, schools and to the general public. This service allows you to watch events from your desktop computer, ‘as they happen’. This service allows people to watch live events from equipped rooms on the CERN Site and provides video recording of these events for future viewing. It is also responsible for providing the video streaming capabilities when watching past events recorded in video from CDS or Indico. The service is also responsible for the audio/video retransmission of events between the main CERN rooms through a dedicated fiber network.
