U.S. EPA Reopens Future TV Set-top Box Program Spec Version 4.0

For years, energy efficiency agencies around the world have been trying to fine-tune a set-top box (STB) program specification that dramatically reduces their energy consumption, especially when consumers have turned them off. Last year, the EPA revised their ENERGY STAR® STB Specification, establishing versions 3.0 and 4.0 (with effective dates of September 1, 2012, and [...]

One specific focus was describing the new “Deep Sleep” feature — a power state within sleep mode characterized by reduced power consumption and increased time required to [...]

A New Lullaby for Set-top Boxes?

The US EPA got closer to finalizing the next ENERGY STAR set-top box (STB) efficiency program requirements with an addition that will allow the devices to go into a much lower power down mode than previous versions. As covered in previous blogs, reigning in STB power consumption has proven to be a little trickier than [...]
