-=====Video Conferencing Basics===== +====Video Conferencing==== 
-Video-enabled meetings happen in two distinct ways: either +  * [[videoconf:basics|Basics]] 
-point-to-point or with multi-point.  +  * [[videoconf:desktop|From the desktop]]
-====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.+
