H.331
H.331 is part of the ITU suite of standards for Video Teleconferencing. This standard is used for broadcast of videoconferences, as opposed to point-to-point links. ''EBU'', 1999. Retrieved 5 January 2012. A standard H.320 terminal (i.e. ISDN endpoint) can be modified to provide one-way point-to-multipoint data transmissions ("broadcasts"). These broadcasts can be likened to television broadcasts. H.331 specifies how H.320 terminals act in situations where there is no data path from receivers back to transmitters, making normal two-way negotiation impossible. In such a situation no MCU is needed. Standard applications include: * Educational Broadcasts (Classes, Campus Events...) * Corporate Broadcasts (Shareholder Meetings, Pub ...

Videoconferencing
Videotelephony (also known as videoconferencing or video calling) is the use of audio signal, audio and video for simultaneous two-way communication. Today, videotelephony is widespread. There are many terms to refer to videotelephony. ''Videophones'' are standalone devices for video calling (compare Telephone). In the present day, devices like smartphones and computers are capable of video calling, reducing the demand for separate videophones. ''Videoconferencing'' implies group communication.Mulbach et al, 1995. pg. 291. Videoconferencing is used in telepresence, whose goal is to create the illusion that remote participants are in the same room. The concept of videotelephony was conceived in the late 19th century, and versions were available to the public starting in the 1930s. Early demonstrations were installed at booths in post offices and shown at various world expositions. In 1970, AT&T launched the first commercial personal videotelephone system. In addition to videoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teleconferencing
A teleconference or telecon is a live exchange of information among several people remote from one another but linked by a communications system. Terms such as audio conferencing, telephone conferencing, and phone conferencing are also sometimes used to refer to teleconferencing. The communications system may support the teleconference by providing one or more of the following: audio, video, and/or data services by one or more means, such as telephone, computer, telegraph, teletypewriter, radio, and television. Internet teleconferencing Internet teleconferencing includes internet telephone conferencing, videotelephony, web conferencing, virtual workplace, and augmented reality conferencing. Internet telephony involves conducting a teleconference over the Internet or a wide area network. One key technology in this area is Voice over Internet Protocol Voice over Internet Protocol (VoIP), also known as IP telephony, is a set of technologies used primarily for voice comm ...
