Telepresence
Telepresence can be described as videoconferencing with a feel of the physical
presence of conferencing partners. With high-definition single or multiple largescreen
displays, advanced codecs, technologies for synchronized display, echo
cancellation, high-definition cameras and specially designed rooms/studios,
conferencing people on opposite ends of the world feel as if they are in the same
room. In the following section, we discuss two major products: Cisco TelePresence
and HP Halo.
Cisco TelePresence
Cisco Systems launched Cisco TelePresence in October 2006 to provide in-person
meeting experience by combining high-definition video, high-quality spatial audio
and an interactive environment under a setup that makes two remote locations appear
in a single conference room. In TelePresence, Cisco uses standard technologies with
specialized hardware and supporting applications.
