Network Electronics Launches Suite of 3Gb/s Video Transport Solutions at NAB 2007

Today the most commonly used HDTV formats are 720P or 1080i. However, moving forward the broadcast industry will transition to 1080p 50/60 for HD due to higher picture quality and the benefits enabled by being able to down-convert to multiple HD and SD formats and standards.

Transporting 1080p50/60 requires twice the bandwidth of the current HD-SDI interface (1.5Gbps), which means that the signal can be transported by either dual link HD (2x 1.5 Gbps) or 3Gbps 3G-SDI Single Link connectivity. At NAB 2007, Network Electronics demonstrates router and optical transport solutions for single link 3G-SDI for HD, offering a number of economic and technical advantage over dual 1.5 Gbps HD transport.

3G-SDI electrical interface :
- Support HD bitrates up to 3Gbps
- Single 75 ohm Coax with BNC
- SDI (SMPTE 259M), HD-SDI (SMPTE 292M) compatible
- Similar performance as existing HD interfaces
- Re-use of infrastructure, BNC, cable, patches etc. for shorter in-house applications
- Physical robustness and simple connectivity

International standards support :
– SMPTE 424M (physical interface)
– SMPTE 425M (format mapping)
– ITU-R BT 1120-3 part 4 2005
