For consumer gear FPGAs are the way of the near future, maybe. Good FPGA chips are expensive. The trade off is field upgrade.
For industrial gear FPGAs are old news. Anyone in the industry who should know this and doesn't should retire.

It is true that hardware evolution basically followed this path: transistors, IC's, huge IC's, Field Programmable Logic Arrays (FPGA). The reapirability of hardware is basically improved if manufacturer makes sure that FPGA and control code can be reloaded in the field. In that case remakcbale changes can be done without turning on soldering iron or opening the box.Mike Tsinberg http://www.keydigital.com -----Original Message----- *From:* Cliff Benham [mailto:flyback1@xxxxxxxxxxx] *Sent:* Friday, April 2, 2010 06:02 PM *To:* opendtv@xxxxxxxxxxxxx *Subject:* [opendtv] Re: Attracting NextGen TV Engineers The problem with "television" today is that everything is a computer running windoz and all the engineers I talk to say they mostly push buttons and reboot things to get them working again. One chief engineer I have known since the '70s says nothing built after 2000 can be repaired in the field. The mfgrs. want the stations to buy maintenance contracts which is most always a board exchange program. So this may explain why there are very few "enginerrs" out there who can actually troubleshoot and repair broadcast equipment down to the component level.

"In contrast, they see television as a dinosaur on its way out. Part of the problem is their lack of knowledge: Most of these graduates think of television as something that comes from a cable or satellite TV spigot. They have no knowledge of terrestrial broadcasting and all the engineering challenges associated with it. As a result, they don't find it to be exciting." > > Lopez agrees that image is a factor in the "move of engineers from broadcast to computer and IT fields." But a lack of perceived challenge and glamour is just part of the problem. The fact is that new engineers believe that they can make a better living working in IT, and have a better home life to boot. > > "Many IT jobs are 8-5 positions with better pay scales, no "on call" status, and the possibility of working from home," he said. "Yet another thing that is occurring is consolidation of broadcast operations into centralized facilities, or existing groups purchasing additional properties and eliminating the duplication of effort and positions. This centralization may have indeed driven some good engineers from broadcasting in search of more stability in their careers." > > That's not all. "Many of the young engineers who might be persuaded to enter broadcasting don't have the RF skills," said Ralph Hogan, SBE vice president and vice president and associate GM of Phoenix DTV stations MCTV and NPR radio stations Sun Sounds, KBAQ, and KJZZ. "We used to get a lot of people with these skills when they retired from the military, where RF was a priority. But now with the military moving more to an IT emphasis, these veterans are going to IT-related companies." > > WHAT CAN BE DONE > > Ralph Hogan has come up with a simple, effective way to make his broadcast positions more attractive to young engineers.

"We need to communicate that broadcast TV is wireless video and data on a grand scale," said Hayes. "Wireless data can't do what we can do. For instance, there were so many wireless demos occurring in Las Vegas at CES 2010, it caused traffic problems on the local cellular network. That just doesn't happen with broadcast TV: We can handle scalability!" > > A third solution is being developed by the IEEE Broadcast Technology Society; namely a new course called "Bridging the Broadcast/IT Gap." Currently under development with support from CNN, ESPN, Fox, NBC and Turner Broadcasting, this course is designed to help broadcast TV engineers become far more comfortable with IT-based technology; notably compression, video and data networks; and seamless file-based editing, storage and play-out. But this same course could be used "to attract IT engineers into broadcasting," said Hogan. "It could help bridge the gap between the two professions." > > Finally, it couldn't hurt to boost the pay and improve the hours of broadcast TV engineers. Unfortunately, the current economy makes this unfeasible for most broadcasters. In the interim, there is still room for broadcasters to pitch their industry at IT students currently in college. Another low-cost option would be for the SBE and IEEE to produce a PSA to run on TV stations playing up the glamour and excitement of broadcast engineering. > > Whatever the over-the-air broadcasting industry does, it needs to start doing it now. As Lopez has pointed out, the current crop of engineers is getting older. When they retire, someone will have to take their place; ironically at a time when digital technology, centralcasting and HDTV are making broadcast television more cutting-edge than ever before. > > > ---------------------------------------------------------------------- > You can UNSUBSCRIBE from the OpenDTV list in two ways: > > - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org > > - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line. > > > ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in thesubject line.
