VideoTele.com Lowers Bit Rates for DTV over xDSL
VideoTele.com Inc., a subsidiary of Tektronix, recently released multipass technology for its Astria content processor, a platform for delivering DTV over xDSL networks. The multipass processor allows service providers to improve bandwidth utilization on existing xDSL networks.

Astria operators can use the multipass processor to lower the overall bit rate of digital video streams while maintaining video quality. When integrated with the Astria's digital signal processing and MPEG-2 compression applications, multipass processing reduces the peak bit rate of a precompressed video source by more than 50 percent.

According to the company, the development will help drive down the cost of deploying video by expanding the number of customers that providers can serve. Lowering the bit rate of each video stream reduces bandwidth requirements on the backbone network, reducing service provider costs.

Eleven FCC Scenarios for The 600 MHz Band Plan
I suspect that the estimated $44 billion of auction proceeds do not take into account the fact that some spectrum the FCC will buy cannot be resold because it must be used as guard intervals in the 600 MHz band plan.~ Charles W. Rhodes
