Abstract: This disclosure provides systems, devices, apparatuses, and methods, including computer programs encoded on storage media, for a DPU enhancement that provides an improved HDCP user experience. A display processor may configure a plurality of frames for a display panel, where each of the plurality of frames may be associated with an authentication level. The display processor may determine whether the authentication level of at least one frame of the plurality of frames is greater than an authentication level of the display panel and, if the authentication level of the at least one frame is greater than the authentication level of the display panel, the display panel may skip/drop a transmission of the at least one frame to the display panel.

Abstract: The present disclosure relates to methods and apparatus for data processing, e.g., a display processing unit (DPU). The apparatus may receive data including a plurality of data bits, the data being associated with at least one data source. The apparatus may also determine whether at least a portion of the data corresponds to priority data, the priority data being within a region of interest (ROI). The apparatus may also detect an adjustment amount of the received data when at least a portion of the data corresponds to priority data, the data being displayed or stored based on the detected adjustment amount.

Abstract: Certain aspects of the present disclosure generally relate to testing functionality of the display system. An example method generally includes selecting a first data integrity check value, associated with a region of interest (ROI) of an input frame, among a set of data integrity check values stored on a memory device, the data integrity check values are associated with an animation comprising a plurality of frames, and at least one of the frames of the animation corresponds to the input frame; processing, with a display processor, the input frame; calculating a second data integrity check value on the ROI of the input frame after the display processor processes the input frame; comparing, with a comparator, the data integrity check values; and generating, with the comparator, an interrupt if the comparison indicates that the values do not match.
