Abstract: A system and method for coding video data in pattern mode for display stream compression (DSC) is disclosed. In one aspect, the method includes determining that a first pattern in a current block of video data is not in a pattern database comprising a plurality of patterns, and adding the first pattern to the pattern database. The first pattern may be associated with a first index identifying a location of the first pattern in the pattern database. The method further includes coding the current block in pattern mode at least in part via signaling (i) the first pattern determined not to be in the pattern database and (ii) the first index identifying the location of the first pattern in the first database.

Abstract: In an embodiment, a user equipment (UE) coupled to a display screen enters into a reduced blue light (RBL) mode. The UE determines, while operating in accordance with the RBL mode, a degree of blue light reduction in at least a portion of a display frame to be output on the display screen using at least one RBL rule from a set of RBL rules that is based upon one or more of (i) application-specific information of an application that is contributing image data to the portion of the display frame, and (ii) content-specific information that characterizes the image data in the portion of the display frame. The UE selectively reduces the blue light in the at least a portion of the display frame based on the determining. The UE sends the display frame with the selectively reduced blue light portion to the display screen for output.

Abstract: A system and method for coding a block of video data in block prediction mode for display stream compression (DSC) is disclosed. In one aspect, the method includes determining a candidate block to be used for predicting a current block in a current slice. The candidate block may be within a range of locations defined by one or more block prediction parameters. The method further includes determining, based on the candidate block and the current block, a prediction vector identifying a location of the candidate block with respect to the current block, and coding the current block in block prediction mode at least in part via signaling the prediction vector identifying the location of the candidate block with respect to the current block.
