Embodiment Construction

[0021] The presently disclosed subject matter provides methods, techniques, systems, structures and articles of manufacture for identifying a pause state in an external video source that provides a video signal to a video display device such as a television or receiver or monitor. Throughout this disclosure, the term "video display device" should be construed to include a variety of devices and devices (such as televisions or video display monitors) and other systems including a video display panel, screen or component and one or more controls or processing A component that controls what is displayed on this video display panel, screen or component. The video signal can be an analog or digital video data stream. This identification may include one or more of a number of methods, including but not limited to the illustrative implementations discussed here. Once the external video source is identified as paused and the paused state persists for more than a threshold time, recei...

Abstract

One or more components of a video display device such as a television set can be powered down in response to a determination that a video input source has been paused. The video signal provided by the video input source can be analyzed to determine whether the video source is paused. When the video input source is no longer paused, the powered down components can be restored to full power operation.

Description

Background technique [0001] Televisions and other video display devices with larger screen sizes are now very common and affordable in the mass consumer market. The power consumption of the display screens and other components of these devices is considerable. In addition, prolonged use can lead to degradation of various components. The power consumption and component degradation of such devices occurs regardless of whether the user is looking at the screen. In some types of televisions, such as plasma and cathode ray tube models, the display of static images can cause the screen to degrade more quickly due to "burn-in". [0002] Currently available video display devices typically have multiple power modes. In active mode, the unit's display, tuner and most other components run at full power. To comply with energy conservation regulations such as Energy Star from the U.S. Energy Protection Agency As a rule, video display devices may include a reduced power feature that...
