摘要： 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.

摘要： Embodiments provide bandwidth efficient mechanisms for delivering rich media content, such as webpages, to receiver devices via a multimedia broadcast network. Content, such as selected webpages, is broadcast as disassembled content elements via the broadcast network. To enable reception, the disassembled content elements are broadcast according to a broadcast schedule that is communicated in an overhead content description flow, such as a catalog file. Receiver devices receive the catalog file and use the metadata information to selectively receive disassembled content and store the content elements in memory. When a user requests access to the content (e.g., a webpage via a web browser), an application operating in the receiver device assembles the requested content from the previously received and stored disassembled content elements, and passes the assembled webpage to a using or rendering application.

摘要： This disclosure describes techniques for performing content adaptive histogram enhancement. In accordance with the content adaptive histogram enhancement techniques of this disclosure, a frame of digital image data, e.g., digital video data or digital still image data, is classified into one of a plurality of content classes based on histogram of pixel intensity values of the frame. The content classes may represent various levels of brightness, contrast, or the like. To classify the frame into the corresponding content class, a shape of the histogram may be analyzed using various histogram statistics. Based on the content class of the frame, the pixel intensity values of the frame are mapped to new pixel intensity values.

摘要： A video decoder performs a sequential error handling process to detect and conceal errors within a corrupted data segment of video data units. The decoder sequentially decodes a current data unit. Upon detecting an error, the decoder sets an error flag and resynchronizes decoding at the start of the next unit. If the error flag is set, the video decoder identifies the end of the corrupted data segment based on the start of the later unit. The decoder conceals data between the start of the current unit and the end of the corrupted data segment. If the error flag is not set, the decoder may decode the remainder of the current unit and proceed to decode the next available unit without performing error handling and concealment for the current unit. The decoder also may address reference unit mismatches caused by lost video data units.

摘要： 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.

摘要： Display of an interpolated or extrapolated video unit, such as a video frame, may be selectively enabled based on a quality analysis. This disclosure also describes selection of reference video frames to be used for interpolation or extrapolation. A decoder may apply a quality-focused mode to select a reference frame based on quality criteria. The quality criteria may indicate a level of quality likely to be produced by a reference frame. If no reference frames satisfy the quality criteria, interpolation or extrapolation may be disabled. A decoder may apply a resource-focused frame interpolation mode to enable or disable frame interpolation or extrapolation for some frames based on power and quality considerations. In one mode, frame interpolation may be disabled to conserve power when reference frames are not likely to produce satisfactory quality. In another mode, the threshold may be adjustable as a function of power saving requirements of the decoder.
