摘要： In an example, aspects of this disclosure relate to a method of coding video data that includes determining a quantization parameter (QP) for coding residual video data, where the QP is indexed to a quantizer step size. The method also includes determining a quantization scaling value for scaling the quantizer step size, and applying the quantization scaling value scaling to the quantizer step size. The method also includes coding the residual video data using the scaled quantizer step size.

摘要： A video decoder converts a block-based LSC indicator into a scan-based LSC indicator. The block-based LSC indicator indicates coordinates of a last significant coefficient of a block of transform coefficients according to a scanning order. The scan-based LSC indicator indicates an ordinal position of the LSC according to the scanning order. The video decoder may decode, based on the scan-based LSC indicator, a significance map for the block.

摘要： At least one particular method and apparatus provide an enhanced quality low resolution image extracted from a scalable high resolution bit stream in a DCP bit stream. In various implementations, an enhancement layer is used to produce the enhanced low resolution image. The enhancement layer may include, for example, spatial-domain or frequency-domain information to be used to enhance the typical low resolution image extracted from a DCP bit stream. One specific process includes encoding a digital image into an encoded image. The encoded image is capable of being processed to provide a higher resolution decoding of the digital image and to provide a lower resolution decoding of the digital image. The process further includes encoding additional information for enhancing the lower resolution decoding to provide an enhanced lower resolution image. A complimentary signal and decoding process are also provided, as well as structures for performing the processes.

摘要： A method and apparatus for controlling the rate of compression in video/image compression environments is provided. The method includes determining a scaling factor that results in a compressed file size as close to a target file size as possible. In determining the scaling factor, tolerance limits of the current file size as compared with a predetermined tolerance is made, and when the tolerance is not met, the current scaling factor is interpolated to generate a new scaling factor, and consideration of a ratio of file sizes is made to determine if a new down-sampling factor is needed for the interpolated scaling factor.

摘要： A system and method for processing video uses a message protocol to communicate between computing units. An image request message is sent to an administrator process of a master node from at least one slave process to request an image to process. Responsive to the request message, an image name message is sent to a requesting slave process from the administrator process to retrieve the image from a queue. The image associated with the image name is processed. Images to process are requested until a completion message is received from the administrator process.
