IEEE Readies for Broadcasting Symposium
The 59th Annual IEEE Broadcast Symposium will take place October 14-16, 2009 at the Weston Hotel in Alexandria, Virginia. As usual, many of the papers will cover DTV transmission and reception.
On Wednesday Sid Shumate will discuss a new implementation of Longley Rice and Greg Best will cover harmonic and spurious measurement methodology according to the IEEE P1631 Recommended Practice. John Kean from NPR Labs will be there to discuss signal coverage measurement techniques for FM radio and IBOC that I suspect will also be of interest to TV engineers.
Thursday's papers include "Revisiting the Field Strength Requirements for DTV in the Canadian Context" and "Experimental Results on Wind Turbines Impact to Terrestrial DTV Reception in UHF Band." Charles Einoff discusses another potential broadcast reception problem: in-house power line telecommunications devices.
Friday's sessions focus on antennas. Merrill Weiss offers an explanation of why modeling mechanical beam tilt in broadcast antennas may not be as simple as you think. Bill Hayes will moderate a panel discussion featuring representatives from TV transmitting antenna manufacturers. I expect circular and elliptical polarization will be among the topics discussed.
In addition to the papers, the Symposium provides an excellent opportunity to network with industry experts. Registration is open now. The IEEE 59th Annual IEEE Broadcast Symposium web page
