Abstract: The invention relates to a method for switching a multimedia source and multimedia sink from an operating mode to a standby mode, and a method for switching a multimedia source and multimedia sink from a standby mode to an operating mode. When the consumer device comprises two distributed boxes, such as a TV in which the display (multimedia sink) is separated from the processing unit (multimedia source) via a cable, then meeting the green rules for standby power becomes more complicated. The power consumption of processing unit and display unit should be minimal in standby mode. The methods of the invention provide for synchronizing the power states of both units, such that only the relevant parts remain active. The method is applicable on configurations where a DisplayPort link is used between a multimedia source, such as a set-top box, and a multimedia sink, such as a display.
