ABSTRACT:
A video display apparatus capable of receiving multiple video input signals and of reducing its power consumption when each of those signals becomes inactive. Power consumption is reduced by selecting from a number of power saving modes. Each power saving mode has an associated recovery time as well as an associated amount of power savings. Recovery time is minimized by determining which of the video input signals is most likely to become active first, assigning a high priority to that signal and selecting a power saving mode based on characteristics of that signal. The likelihood of reactivation of a signal is determined by detecting the absence of normal vertical and/or horizontal synchronization signals.
