摘要：<p>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. The invention provides a reduction in overall power consumption, while still complying with the DisplayPort configuration and operation standard. In an embodiment of the invention, the source and sink are configured to allow communication of standby and wake-up requests/commands when the transmitter and receiver for the auxiliary channel are powered down. The invention also provides embodiments where the switching to and from standby of the source is triggered by user interaction with the sink. This is convenient because the source is often hidden from view, and contributes to an improvement in power consumption reduction because the user no longer needs to monitor and control the mode of the source - the user can simply monitor and control the mode of the sink, which is mostly in view.</p>
