    Abstract: Innovations in content mastering operations performed during playback of high dynamic range (“HDR”) video on a display device are described. When content mastering is performed during playback on a display device, a video playback system can use details retained for input HDR video (e.g., retained in metadata) and the properties of the display device to improve the perceptual quality of the HDR video as shown on that display device. For example, the video playback system can use an energy-preserving bloom operator to make bright highlights “bloom” into adjacent areas, thereby accentuating the bright highlights in the HDR video while operating within the constraints of the display device. The video playback system can also perform various other types of operations when content mastering is deferred until playback, including application of a lens flare operator as well as alternative tone mapping operators and alternative color gamut mapping operators selected according to metadata.

A content element is determined to be eligible for compression based on one or more characteristics of the content element. A rate module determines a compression rate for each of the one or more content elements. The compression rate comprises an amount of compression to be applied to a content element. The amount of compression to be applied to the content element is determined as a function of one or more characteristics of the content element. A compression module compresses each of the one or more eligible content elements according to the determined compression rate.

  • Patent number: 9965876
    Abstract: A graphics processing pipeline determines whether respective graphics processing operations, such as respective blends, respective depth tests, etc., to be performed at a stage of the graphics processing pipeline would produce the same result for each sampling point of a set of plural sampling points represented by a fragment being processed by the graphics processing pipeline. If it is determined that respective graphics processing operations would produce the same result for each of the sampling points, then only a single instance of the graphics processing operation is performed and the result of that graphics processing operation is associated with each of the sampling points. The number of instances of the graphics processing operations needed to process the set of plural sampling points which the fragment represents is reduced in comparison to conventional multisampling graphics processing techniques which perform graphics processing operations for fragments on a “per sample” basis.

  • Patent number: 9940733
    Abstract: Data destined for memory, i.e., data that was evicted at some level in the cache hierarchy is intercepted and subjected to compression before being sent to memory. Thereby, when the compression is successful, the memory bandwidth requirement is reduced, potentially resulting in higher performance and/or energy efficiency in some embodiments.

  • Patent number: 9894374
    Abstract: A method for encoding high dynamic range (HDR) images involves providing a lower dynamic range (LDR) image, generating a prediction function for estimating the values for pixels in the HDR image based on the values of corresponding pixels in the LDR image, and obtaining a residual frame based on differences between the pixel values of the HDR image and estimated pixel values. The LDR image, prediction function and residual frame can all be encoded in data from which either the LDR image of HDR image can be recreated.

  • Patent number: 9794126
    Abstract: Apparatus and associated methods relate to compressing a sequence of binary data by encoding difference values between adjacent data in the sequence. For each datum in the sequence, the difference value may be determined by comparing the datum with an immediately preceding datum. For data, the determined difference may be expressible using few bits. The determined difference is encoded in subwords having subword lengths selected from a set of predetermined subword lengths. The selected subword lengths may be a minimum one of the set of predetermined subword sizes that is capable of representing the difference between the adjacent data. A size tag is generated for each subword encoded. The size tag identifies the size of the subword selected and used for encoding the determined difference. The difference may be encoded as a mathematical difference or as a bit pattern difference.

  • Patent number: 9778928
    Abstract: It may be determined that a payment reader requires a firmware update, which may be transmitted to the payment reader as compressed firmware update blocks. The payment reader may receive a first portion of set of the compressed firmware update blocks. The payment reader may decompress the first portion and determine a partial firmware offset associated with the first portion. If the firmware update is incomplete, the payment reader may transmit that partial firmware offset to a second device. Based on this partial of firmware offset and an offset table that associates compressed firmware offsets with decompressed firmware offsets, the payment reader receive a second portion of compressed firmware update blocks to send to the payment reader. The payment reader may determine that entire update has been received and update its firmware.

  • Patent number: 9760310
    Abstract: Embodiments of the present invention allow a data segment stored in a compressed format to be directly staged into a cache allowing access to the data segment. In operation, a request to access a data segment is received. In response, whether the data segment is stored in a compressed format is determined. If the data segment is stored in the compressed format, the data segment is staged directly into a cache.

  • Patent number: 9761043
    Abstract: Systems and methods provide for non-multisampled anti-aliasing for clipping paths, in which a non-multisampled texture is employed to store anti-aliasing data. In some configurations, clipping paths applied to an input object are processed successively using a non-multi-sampled buffer and non-multisampled texture. Each clipping path is processed by incrementing a stencil buffer value for each pixel covered by the clipping path, computing clipping path coverage data, and storing the clipping path coverage data in the non-multisampled texture. An object is rendered by performing a stencil test and multiplying color values for retained pixels by corresponding texture values from the non-multisampled texture to provide anti-aliasing. Further configurations operate without a stencil buffer but employ a logical stack of non-multisampled textures, one for each clipping path.

  • Patent number: 9736488
    Abstract: A two-stage context adaptive binary arithmetic coding (CABAC) parser is provided to efficiently transcode an input video bitstream that is partitioned into tiles into a non-tiled based video bitstream. A picture of the input video bitstream is partitioned into one or more tiles, each of which has multiple coding tree units (CTUs) according to the HEVC standard. The two-stage CABAC parser parses the input video bitstream in tile scan order in the first stage and generates a list of identified CTUs, whose CABAC state data are saved for the second stage parsing. In the second stage parsing, the two-stage parser parses the same input video bitstream in raster scan order using the saved CABAC state data of the identified CTUs.

  • Patent number: 9652384
    Abstract: Techniques and mechanisms to efficiently cache data based on compression of such data. The technologies of the present disclosure include cache systems, methods, and computer readable media to support operations performed with data that is compressed prior to being written as a cache line in a cache memory. In some embodiments, a cache controller determines the size of compressed data to be stored as a cache line. The cache controller identifies a logical block address (LBA) range to cache the compressed data, where such identifying is based on the size of the compressed data and on reference information describing multiple LBA ranges of the cache memory. One or more such LBA ranges are of different respective sizes. In other embodiments, LBA ranges of the cache memory concurrently store respective compressed cache lines, wherein the LBA ranges and are of different respective sizes.
