Antennas Direct is exhibiting the CEA-909A-enabled Smart Antenna it developed in partnership with the NAB at CEDIA 2008, from now until Sunday, Sept. 7 at the Colorado Convention Center in Denver. The directional pattern of the CEA-909A antennas can be changed electronically to optimize performance for individual DTV channels using a single-wire protocol from the ATSC tuner.
"Smart antenna technology can make a huge difference in the overall consumer experience, allowing access to all local television signals without having to spend a lot of time aiming or re-aiming antennas," said Lynn Claudy, NAB's senior vice president of Science and Technology.
Richard Schneider, president of Antennas Direct, added, "This effective and practical design of the antenna allows it to be affordable; we believe the antenna would not be marketable if the cost exceeded $150."
Antennas Direct exhibited a fixed (dumb?) indoor antenna and an ATSC digital-to-analog converter combined in a small bookend-sized box at the ATSC Hot Spot at the 2008 NAB Show. That struck me as a better solution for viewers using indoor antennas with their analog TV sets than converter boxes alone. If Antennas Direct can combine a CEA-909A Smart Antenna in an attractive package with a digital-to-analog converter, it should be the ideal solution for non-technical analog TV viewers converting to digital.
