Abstract:
1. A method comprising: accessing, by a processor, a display list of a media item, wherein the display list comprises a plurality of display objects of the media item, wherein each display object of at least two of the plurality of display objects has a respective first attribute controlling a first display characteristic of the display object and a respective second attribute controlling a second display characteristic of the display object; selecting, by the processor, display object from the at least two of the plurality of display objects; encoding, by the processor, a designator in a first attribute of the selected display object, wherein the designator is indicative of an origin of the media item; and modifying, by the processor, a second attribute of the selected display object to have a respective value preventing the processing of the selected display object from resulting in the selected display object having any displayable feature, wherein modifying the second attribute of the selected display object to have the respective value comprises setting the respective value of the second attribute to a null value, the null value causing the second attribute to be interpreted by the rendering application as a null operation and causing the selected display object to be processed by the rendering application as a null display object not displayed in a rendered instance of the media item.
