NBC Universal HD launch relies on DVB-S2 8PSK modulators
For the launch of its new HD channels, including Bravo HD, USA HD, Sci-Fi HD and CNBC HD, which premiered Oct. 3, NBC Universal is relying on a combination of compression products from TANDBERG Television.
NBC Universal is the first in the United States to use TANDBERG Television DVB-S2 8PSK modulators with Prekor to distribute programming to service providers. The DVB-S2 modulation standard is designed to increase the throughput of a satellite transponder, or increase downlink margins for better reception. Prekor optimizes the use of DVB-S2 8PSK modulation by pre-correcting for distortions that can reduce the maximum transmitted bit rate.
NBC Universal also is using TANDBERG Television’s Director Advantage service, a turnkey managed solution for the deployment of IRDs, and a multiservice decryptor fully integrated with the Director system.
