Coaxial Cable Issues with 3 Gbit/sec Video
In the professional broadcast and production world HD video is usually produced in one of two formats, 1080i/60 and 720p/30. Both are commonly distributed in a serial digital bit stream over a high-definition serial digital interface (HD-SDI) running at a data rate of 1.5 Gbits/sec. These formats are not the end-point in the search for ultimate picture resolution and quality. The next step is 1080p/60, which requires twice the distribution data rate—3 Gbits/sec. This paper outlines why 1080p was desired, and concentrates on how such signals are carried and how installations can accommodate the higher bandwidth and data rate of these HD signals.
