Digital-to-Analog Converter Boxes Key Product Criteria

Digital-to-analog converter boxes (DTAs) must meet both On and Sleep Mode requirements and incorporate an auto-power down feature after four hours or less of user inactivity to earn the ENERGY STAR.

Digital-to-Analog Converter Boxes Key Product Criteria

Mode Power Consumption under Test Conditions Effective Date: January 31, 2007
On Mode* less than or equal to 8 watts
Sleep Mode less than or equal to 1 watt
* DTA must incorporate an auto-power down feature to automatically switch from the On state to the Sleep state after a period of time without user input. This capability shall be enabled at the factory as the default setting for the device. The default period of inactivity before the equipment automatically switches to the Sleep state shall be four hours or less. Eligible equipment may allow the current program to complete before switching to the Sleep state. The default energy related settings may not be altered during the initial user set-up process and shall persist unless the user chooses at a later date to manually:
  1. disable the "automatic switching to Sleep state" capability, or
  2. adjust the default time period from 4 hours or less to some other value.

DTAs may come out of Sleep Mode in order to scan for program and system information or private data (PSIP). When doing so, DTAs may exceed the 1 watt Sleep Mode requirement for no longer than one hour in an eight hour period. If the 1 watt Sleep Mode requirement is exceeded for longer than this, the DTA will not be eligible to qualify for ENERGY STAR.
