Storage and carriage of green metadata for display adaptation

摘要

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.

主权项

1. A user equipment (UE), comprising:
a receiver configured to receive Display Adaption Metadata (DAM), wherein the DAM is configured in an International Standards Organization Base Media File Format (ISOMBFF) or a Motion Pictures Expert Group 2 (MPEG-2) Transport system (M2TS); a processor configured to:
determine a constant backlight voltage time interval value from the DAM, andin response to determining that a number of constant-backlight-voltage-time-interval values is greater than 1, send the DAM to a display with a lead time relative to a video composition time greater than or equal to a largest constant backlight voltage time interval value; andthe display configured to, when receiving the DAM with a lead time greater than or equal to the largest constant-backlight-voltage-time-interval value, adjust its control settings with sufficient time in advance of displaying the associated media data.
