This edition adds methods for measuring On (aver
44、age) mode power consumption of television sets as defined in Clause 11. The power consumption of many televisions varies depending upon the video signal being displayed. Clause 11 includes three different video signals: static, dynamic broadcast-content, and Internet-content. For information about t
45、he three video signals and guidance on which signal(s) to use, see Annex C. For additional considerations regarding average television power consumption, see Annex B.
