High-Efficiency Set-Top Boxes
Set-top Boxes: High-Efficiency vs. Standard
High-Efficiency electronic devices that convert incoming data signals to a format usable by a TV or computer monitor with low standby power and other efficiency strategies.
Set-top boxes (STBs) have been available for roughly 60 years and now include cable boxes, satellite receivers, digital TV adapters,DVRs & IPTV receivers, Apple TV, and gaming consoles such as PlayStationand Xbox. Energy use of some of these products is more than ten times that of other products. Energy use in standby mode is relatively highdue to the products’ need to continue to communicate with the Internet. Becausethese devices constantly draw power even during sleep or standbymodes, and because of the increasing variety and proliferation of STBs in American homes, it is important to increase the energy efficiency of these units. This can be achieved by reducing the power draw during operation and during sleep/standby modes and by reducing the time elapsed until standby/sleep mode is automatically engaged. The STB industry recently developed a voluntary standard to improve the efficiency of their products but additional improvements could be made. While STBs alone could account for 4% of total residential energy use and have proliferated greatly in recent years, as more TVs become all digital, the need for STBs could diminish.

Energy Savings Rating:
Extensive Assessment What's this?
|1||Concept not validated||Claims of energy savings may not be credible due to lack of documentation or validation by unbiased experts.|
|2||Concept validated:||An unbiased expert has validated efficiency concepts through technical review and calculations based on engineering principles.|
|3||Limited assessment||An unbiased expert has measured technology characteristics and factors of energy use through one or more tests in typical applications with a clear baseline. |
|4||Extensive assessment||Additional testing in relevant applications and environments has increased knowledge of performance across a broad range of products, applications, and system conditions. |
|5||Comprehensive analysis||Results of lab and field tests have been used to develop methods for reliable prediction of performance across the range of intended applications.|
|6||Approved measure||Protocols for technology application are established and approved.|
