In many places radio frequencies or fiber cannot reasonably be used to carry signals of HD television, as when covering the New Year's Eve celebrations in Times Square, or a permanent HD video link is required. The Dramatic growth of HD coverage of these special events, in addition to sporting events and other forms of programming, it has created the need for new video streaming solutions that work easily in CONGESTED RF cities, airports loaded with radars, and other retarding environments. That solution is Canon's Canobeam DT-150 HD transceiver, which can transmit video, audio and camera control signals uncompressed, wirelessly, with a large width of band (HD-SDI and SD-SDI), with bidirectional link without delays using convenient and freely used optical signals.
The Canobeam DT-150 HD transmitter/receiver, displayed on the NAB 2008 event, which drives Canon's global leadership and the expertise in optical technologies, is the new member of Canon's acclaimed series of optical transceivers point-to-point free space, which employ infrared light to provide coverage in situations that require transmissions high bandwidth. In addition to the transmission of a 1.5 Gbps stream of embedded digital video, audio and signals camera control over a single HD-SDI or SD-SDI signal, the Canobeam DT-150 HD transceiver can carry embedded video of HD-SDI and SD-SDI from multiple cameras or other sources of HD/SD video, along with return video and audio embedded towards the camera operator, or control data robotic camera. The Canobeam DT-150 HD transceiver has a range of up to one kilometer and like all Canobeam DT-100 series products offers features Canon-exclusive self-tracking to maintain alignment of the beam of light despite the vibration due to the wind, to the rain or unstable camera platforms.
The Canobeam DT-150 HD transceiver has been used in the broadcasting industry and mobile production for HD sports and entertainment television broadcasts, where fiber optics or RF were not practical. The Canobeam DT-150 HD transceiver provides a transmission solution transparent and economical, point-to-point, digital signals uncompressed, and is playing an important role in the industry in the transition to HD for all types of production locations.
The Canobeam DT-150 HD also offers a major breakthrough to the Canobeam DT-100 series, with the addition of the modular system Small Form Pluggable (SFP). The use of an SFP HD module allows the Canobeam DT-150 HD to interface to fiber optics single-mode using LC connectors. Users who have already used single-mode fiber optic connections, they can simply connect to Canobeam DT-150 HD transceiver and instantly stream embedded video, audio and camera control via FSO connection. Users who do not have a connection existing single-mode fiber optics, they will still be able to use third-party media converters to convert the HD-SDI signals or SD-SDI signals from coaxial or hybrid cables SMPTE fiber optic, for transmission over optical fiber single-mode. As with any SDI link, audio and, or, multiple video signals, these will be embedded within the stream using a multiplexer.
All Canon Canobeam products, including DT-150s HD, use free space optics, which does not require licensing by regulatory bodies or the frequency planning. Free space optics provide highly secure and reliable video and audio links, the which operate free of RF interference and interception signal. Canon's other series of Canobeam DT-100 systems, is comprised of proven high-bandwidth solutions for data networks used in corporations, properties university and military or governmental entities, and others situations where the existing bandwidth is insufficient, the fiber optics are prohibitive due to their costs or logistics is impossible, or where a redundant system for recovery of disasters are essential.
In addition to its temporary use for television events of HD and SD live as golf tournaments, where the ponds and alleys cannot be linked by fiber optic cables; the main outdoor concerts where remote platforms for cameras make the links of impractical fiber optics, or sporting events where the images from unattended and robot-operated cameras require to be connected to a central point from locations Inaccessible, the Canobeam DT-150 HD transceiver can also be used for permanent installations. The latter include Studio/Transmitter Links (STLs) or other high-bandwidth video connections between buildings in broadcasting centres, TV stations or media production complexes.
