Abstract

A method for providing display adaptation metadata (DAM) to a user equipment (UE) at a system level is provided. The method includes configuring DAM for storage in an ISO Base Media File Format (ISOBMFF). The method also includes transmitting the DAM to a UE to control an energy consumption of a presentation on a display of the UE. A method for providing display adaptation metadata (DAM) to a user equipment (UE) at a system level is provided. The method includes configuring DAM for carriage in an MPEG-2 transport system (M2TS). The method also includes transmitting the DAM to a UE to control an energy consumption of a presentation on a display of the UE.

Description

technical field [0001] The present disclosure relates generally to reducing energy consumption in wireless mobile communication devices, and more particularly to storage and delivery of metadata for display adaptation (DA). Background technique [0002] The display resolution of mobile devices has improved significantly. Rendering to large displays will quickly drain battery levels, especially for video where high frequency framebuffer replenishment is required. Metadata-based display adaptation reduces power consumption for LCD and OLED. For LCD displays, power consumption is a monotonic function of the backlight level. For OLED displays, power consumption is a monotonic function of supply voltage. Green metadata derived from image statistics is used to control the backlight (or supply voltage) to provide maximum power reduction. Green metadata also enables trade-offs between power reduction and perceived video quality. Contents of the invention [0003] technical pr...
