PROBLEM: |
|
Television broadcasters have begun retooling their infrastructure to accommodate the bandwidth demands of high-definition television (HDTV), which promises to change the industry as indelibly as the advent of color televisions did in the 1960s. During 2006, an estimated 50 percent of all televisions in homes will be HDTV-ready. Further fueling high-definition TV growth, President George Bush has signed legislation mandating that broadcasters transition to all digital content by February 17, 2009 |
|
|
|
Broadcasters have found that remote deployments of fiber-optic cable can be costly, time consuming or—in some instances—impossible. For example, it may take more than a mile of fiber-optic cabling to provide HDTV remote camera coverage for a sporting event. Lower-speed connectivity alternatives, such as wireless radio frequency (RF) or digital microwave do not offer enough bandwidth to carry raw high-definition video. |

SOLUTION: |
| |
|
| Broadcasters seeking real-time HDTV video and embedded audio feeds from annex studios or remote locations find that optical wireless offers great advantages in terms of cost, capability and simplified operation. Specially engineered optical wireless links meet HDTV standards of 1.485 Gbps and provide license-free connectivity based on free-space optics (FSO) technology. These high-speed links can provide broadcasters with the throughput of fiber optics without the installation difficulties and delays. |
| |
| Optical wireless also eliminates compression requirements and transmission quality concerns, technical training requirements and licensing expenses associated with other connectivity alternatives. |
