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. ## Claims ### Claim 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, and in 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; and the 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. ### Claim 2 (depends on 1) The UE of claim 1, wherein the DAM comprises at least one receiver dependent metadata, contrast-enhancement metadata, or non-aggregated quality levels, and wherein the DAM is associated with a particular packet of media data. ### Claim 3 (depends on 1) The UE of claim 1, wherein the receiver is configured to receive media data concurrently with the DAM. ### Claim 4 (depends on 3) The UE of claim 3, wherein at least one of the media data or the DAM is configured such that the processor begins processing the DAM before the processor begins processing the media data. ### Claim 5 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. ### Claim 6 (depends on 5) The method of claim 5, wherein the DAM comprises at least one of receiver dependent metadata, contrast-enhancement metadata, or non-aggregated quality levels, and wherein the DAM is associated with a particular packet of media data. ### Claim 7 (depends on 5) The method of claim 5, further comprising receiving media data by the UE. ### Claim 8 (depends on 7) The method of claim 7, wherein receiving comprises the receiving media data concurrently with the DAM. ### Claim 9 (depends on 8) The method of claim 8, wherein at least one of the media data or the DAM is configured such that the UE begins processing the DAM before the UE begins processing the media data. ### Claim 10 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. ### Claim 11 (depends on 10) The non-transitory computer readable medium of claim 10, wherein the DAM comprises at least one of receiver dependent metadata, contrast-enhancement metadata, or non-aggregated quality levels, wherein the DAM is associated with a particular packet of media data. ### Claim 12 (depends on 10) The non-transitory computer readable medium of claim 10, wherein the plurality of instructions is configured to cause the processor to process the DAM before processing the media data. ### Claim 13 (depends on 12) The non-transitory computer readable medium of claim 12, wherein at least one of the media data or the DAM is configured so that the plurality of instructions cause the processor to begin processing the DAM before the processor begins processing the media data. ### Claim 14 (depends on 10) The non-transitory computer readable medium of claim 10, further comprising receiving media data. ### Claim 15 (depends on 14) The non-transitory computer readable medium of claim 14, wherein the media data is received concurrently with the DAM. ### Claim 16 (depends on 15) The non-transitory computer readable medium of claim 15, wherein at least one of the media data or the DAM is configured such that the processor begins processing the DAM before the UE begins processing the media data.
