 ====Public Video Conferencing Units====
 These units can be used freely by all Sterrewachters, provided a reservation has been made through the Observatory secretariat (Oort 465).

-Video-enabled meetings happen in two distinct ways: either
-point-to-point or with multi-point.
-====Point-topoint video conferncing====
-In point-to-point, the simplest
-scenario is where one person or group is connected to another.
-The physical components (i.e. microphone and camera) that
-enable the meeting to take place are often integrated in to
-desktop computing solutions like a laptop or tablet, or can be
-combined into dedicated, room-based hardware solutions.
-Where desktop solutions tend to be used by individuals,
-room-based solutions utilize dedicated video conferencing
-technology where groups of people can be seen, heard and
-can naturally participate in the meeting.
-====Multi-point video conferencing====
-In multi-point video calls, three or more locations are
-connected together, where all participants can see and hear
-each other, as well as see any content being shared during
-the meeting.
-In this scenario, digital information streams of voice, video
-and content are processed by a central, independent software
-program. Combining the individual participant’s video and
-voice traffic, the program re-sends a collective data stream
-back to meeting participants in the form of real-time audio
-and video imagery.
-====Protocols====
-As video conferencing technology has evolved, two main
-protocols have emerged to provide the signalling control
-for the establishment, control and termination of video
-conferencing calls: SIP (Session Initiation Protocol) and H.323.
-For the encoding and decoding of visual information, the
-industry is moving towards the industry standard known as
-H.264, which was developed to provide high-quality video at
-lower bandwidth over a wide range of networks and systems.
-An extension to the H.264 protocol is Scalable Video Coding
-(SVC), which is established to facilitate the enablement of video
-conferencing on a wider range of devices, such as tablets and
-mobile phones.
