Washington – The second tier of the
2.0 Audio/Video specification
will take effect on July 30, when the federal government expands the Energy
Star program to cover any A/V product that includes a disc player or audio
Such products include DVD/Blu-ray players, home-theater
receivers, and commercial audio amplifiers.
The second tier also imposes more stringent energy
performance requirements on all A/V products. Products will have to
automatically power down to a low power state after a period of inactivity, an
Energy Star spokesperson said. Most products that carry the Energy Star label
will automatically transition into a low power state after no more than two
hours of inactivity.
With the change, the Energy Star label will identify
products that are efficient through all use phases, the spokesperson added. A
home-theater receiver, for example, will have to meet sleep-mode power-consumption
limits as well as minimum amplifier efficiency limits during audio playback.
