Storage and carriage of green metadata for display adaptation

A method, comprising:

• receiving, by a UE, display adaptation metadata (DAM), wherein the DAM is configured in an International Standards Organization (ISO) Base Media File Format (ISOBMFF) or an MPEG-2 Transport System (M2TS);
• determining, by the UE, a constant backlight voltage time interval value from the DAM;
• in response to determining that the number of constant-backlight-voltage-time-interval values is greater than 1, making the DAM available 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;
• and
• based on the DAM made available to the display with a lead time greater than or equal to the largest constant-backlight-voltage-time-interval value, adjusting by the display, its control settings with sufficient time in advance of displaying the associated media data.

A non-transitory computer readable medium comprising a plurality of instructions that, when executed by a processor, are configured to cause the processor to:

• receive display adaptation metadata (DAM), wherein the DAM is configured in an International Standards Organization Base Media File Format (ISOMBFF) or in a Motion Pictures Expert Group 2 (MPEG-2) transport system (M2TS);
• determine a constant backlight voltage time interval value from the DAM;
• in response to determining that the number of constant-backlight-voltage-time-interval values is greater than 1, make the DAM available 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;
• and
• based on the DAM made available to the display with a lead time greater than or equal to the largest constant-backlight-voltage-time-interval value, adjust display control settings with sufficient time in advance of displaying the associated media data.
