From 1st December 2008 in Australia and 1st April 2009 in New Zealand, Set Top Boxes manufactured or imported for sale in Australia or New Zealand will be required to meet minimum energy performance requirements (MEPS).
Pre-registration is now available (from August 2008) (see making an application for MEPS for details).
The STB must be measured in accordance with the test standard AS/NZS 62087:2004 or the forthcoming AS/NZS 62087.1(Int). Measurements of the passive standby, active standby and on mode power use are required, depending on the type of STB. To comply with MEPS, a STB must not exceed the power limits specified in the standard AS/NZS 62087.2.1:2008 as set out below.
MEPS is defined in terms of a Maximum Platform Allowance (MPA) power level for active standby and on mode that is dependent on the type of STB and what MEPS option is chosen. The MPA is essentially the maximum power requirements for a basic STB, described in the standard. If a STB has features in addition to those shown in the standard, an additional features allowance (AFA) is added to the MPA, up to a maximum power limit (MPL) that must not be exceeded. The measured power consumption of the STB must not exceed the MPA + AFA (for applicable features); and it must not exceed the MPL regardless of how many features are available in the STB. The formula to determine the applicable MEPS level for a particular STB is MPA + AFA < MPL.
The standard also specifies a maximum passive standby power level, if relevant, for that type of STB.
A summary of these power limits is shown in Table 1 for Free To Air DTV STB and in Table 2 for Subscription TV DTV STB.

A DTV STB may be designated as 'high efficiency' and marked as such in product literature if it meets the following requirements:
These features ensure that the STB is able to automatically switch itself into passive standby mode after a period of inactivity or in conjunction with the users switching other audio visual devices connected to the STB into passive standby.
