The Tandberg C90 is a videoconferencing codec and telepresence engine produced by the Norwegian company Tandberg. It is used as the basis for Tandberg's telepresence solutions T1 and T3.
Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance of being present, or to have an effect, via telerobotics, at a place other than their true location.
Norway, officially the Kingdom of Norway, is a Nordic country in Northwestern Europe whose territory comprises the western and northernmost portion of the Scandinavian Peninsula; the remote island of Jan Mayen and the archipelago of Svalbard are also part of the Kingdom of Norway. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land.
Tandberg was an electronics manufacturer located in Oslo, Norway and New York City, United States. The company began in the radio field, but became more widely known for their reel-to-reel tape recorders and televisions. The original company went bankrupt in 1978 after a sharp financial downturn. The following year, the company re-formed whilst their data division was split off as Tandberg Data, including the tape recording division, which reduced its scope to data recording.
The C90 was announced in June 2008, and started shipping in October. [1] In addition to being a telepresence engine, the C90 is available as a stand-alone product, mostly targeted at auditoriums, boardrooms, and large meeting rooms. The C90 supports both H.323 and SIP, and uses H.263, H.263+, and H.264 for video. [3]
H.323 is a recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point conferences.
The Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, and terminating real-time sessions that include voice, video and messaging applications. SIP is used for signaling and controlling multimedia communication sessions in applications of Internet telephony for voice and video calls, in private IP telephone systems, in instant messaging over Internet Protocol (IP) networks as well as mobile phone calling over LTE (VoLTE).
H.263 is a video compression standard originally designed as a low-bit-rate compressed format for videoconferencing. It was developed by the ITU-T Video Coding Experts Group (VCEG) in a project ending in 1995/1996 as one member of the H.26x family of video coding standards in the domain of the ITU-T, and it was later extended to add various additional enhanced features in 1998 and 2000. Smaller additions were also made in 1997 and 2001, and a unified edition was produced in 2005.
The Tandberg C90 was recognized as the "Most Innovative Audio/Video Conferencing Product" at the AV awards ceremonies at InfoComm 09. [4]
