Comments on: The CEA Fails to Dissuade the CEC http://www.displaysearchblog.com/2009/11/the-cea-fails-to-dissuade-the-cec/ The Official Blog of DisplaySearch, an NPD Group Company Fri, 12 Mar 2010 05:49:05 +0000 http://wordpress.org/?v=2.7.1 hourly 1 By: David Barnes http://www.displaysearchblog.com/2009/11/the-cea-fails-to-dissuade-the-cec/comment-page-1/#comment-2672 David Barnes Wed, 25 Nov 2009 17:54:25 +0000 http://www.displaysearchblog.com/?p=1024#comment-2672 As the representative of the LCD TV Association at the CEC hearing, I can attest that you (Paul) identified the contradition that bothered the commissioners during my testimoney and the testimony of others correctly. The LCD TV Association supported the regulation in general but some members worried about power limits if they added unidentified functions to TV sets in the future. As you indicated, the trend of LCD technology leads to less power consumption but the well-known power-speed law suggests that computational power consumption could rise if future sets had nearly super-computer capabilities for bionic input/output. For this reason, some members of the association preferred no power limits. The other factor leading to worry was incomplete understanding of the proposed test methods. The regulation states that power consumption will be measured with extra features turned-off. Therefore, if set designers prepare properly, the interface between your TV set and your cyclotron (just kidding) would be switched off during the test. I think brands can work with the CEC testers to add value to their products without breaking their power budget. In my opinion, Ken Lowe of Vizio offered the most insightful comment during the hearing. He warned that the regulation could cause a surge of service calls to brands, retailers and cable companies until consumers get used to the new spec. The operational spec calls for the TV picture to go black (off) when there is no input. That's logical but that means the TV will go dark when a DVD is ejected or when the player is turned-off, if the user doesn't switch input modes first (e.g. to antenna). That suggests a problem of education far greater than the problem of educating set designers.
