USDTV Switching to MPEG-4 AVC Compression
USDTV is converting its entire terrestrial DTV transmission network to MPEG-4 AVC compression, starting this summer. USDTV currently uses bandwidth of local broadcast DTV stations to transmit up to 30 DTV channels to subscribers with a USDTV set-top box. The company says that MPEG-4 requires less than half the data bandwidth per channel, as compared with MPEG-2. USDTV will demonstrate live MPEG-4 AVC broadcasts over its terrestrial DTV network at ATSC DTV Hot Spot at the NAB2006.

Richard Johnson, co-founder and COO of USDTV said, "Leveraging new technology is at the heart of what we do at USDTV. Since our inception we have been building a team of highly experienced engineers in digital TV technology including MPEG-4 AVC. Our ability to launch an all MPEG-4 AVC end-to-end network in less than 12 months of development is evidence of our commitment to technology."

USDTV customers won't have to buy new set-top boxes to receive the MPEG-4 channels. Garry Paxinos, senior vice president of engineering and chief technologist said, "We set our sights early on to create proprietary technology that would leverage the significant compression capabilities of MPEG-4 AVC. Our engineers have designed an innovative plug-and-play device that connects to the USB port of our existing boxes and provides real-time transcoding from MPEG-4 AVC to MPEG-2, all without compromising video quality or security."

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
