摘要： Techniques and tools for performing fading compensation in video processing applications are described. For example, during encoding, a video encoder performs fading compensation using fading parameters comprising a scaling parameter and a shifting parameter on one or more reference images. During decoding, a video decoder performs corresponding fading compensation on the one or more reference images.

摘要： The present invention is directed towards systems and methods for aggregating and providing statistics from cores of a multi-core system intermediary between one or more clients and servers. The system may maintain in shared memory a global device number for each core of the multi-core system. The system may provide a thread for each core of the multi-core system to gather data from the corresponding core. A first thread may generate aggregated statistics from a corresponding core by parsing the gathered data from the corresponding core. The first thread may transfer the generated statistics to a statistics log according to a schedule. The system may adaptively reschedule the transfer by monitoring the operation of each computing thread. Responsive to a request from a client, an agent of the client may obtain statistics from the statistics log.

摘要： Architecture for providing feedback to a viewer and/or contributor on fashion and other personal appearance decisions that the contributor desires. The contributor uploads self images for viewing and rating (or voting) by viewers who choose provide an opinion on different fashion and/or cosmetic looks of the contributor. The contributor takes images show the contributor presented with a number (e.g., two) of different fashion choices. The snapshots can then be processed for upload to a website or other accessible location by one or more viewers. The viewers can cast a vote for one of the images by selecting the desired image, in response to which the viewer and/or contributor will be presented with overall statistics for that set of images as to how other viewers voted, as well as a next set of photos depicting the user in a different fashion and/or cosmetic choice. This process can continue until terminated.

摘要： A digital media encoder/decoder performs quantization/dequantization based on quantization parameters taken from a harmonic quantizer scale. The harmonic quantizer scale can include a normal portion consisting of quantization parameter values harmonically-related as simple fractions of each other, and a denormal portion of quantizers having a linear or other relation. The encoder/decoder further supports a scaled quantizer mode where quantization is performed based on the quantization parameter as scaled by a fractional value. A compressed domain contrast adjustment is effected by adjusting the quantization parameters in the compressed bitstream, without having to adjust and recode the digital media data in the compressed bitstream.

摘要： Described is a pipeline for handling notification messages sent to a mobile messaging message (e.g., SMS or SMTP) recipient, and handling a reply to that notification message, including correlating the notification message with the reply. An engine receives a notification message, and for a notification message to which a reply is possible, maintains state data for use in correlating a received reply with the notification message. The state data includes metadata that indicates that text or code data is expected in any reply. For a reply providing code data, the engine calls a selected URL corresponding to the code. To facilitate message delivery, the engine may format the notification message, including shortening a URL of the message, and/or splitting a longer notification message into shorter notification messages.

摘要： A check for determining the appropriateness of physical design data is provided, where the check includes both a physical component and a logical component. Based upon the logical component of the check, portions of the physical design data that correspond to the logical component are identified and selected. After the portions of the physical design data corresponding to the logical component have been selected, this physical design data can be provided to a physical design analysis tool, along with the physical component of the design check. The physical design analysis tool can then use the physical component of the design check to perform an analysis of the selected physical design data.

摘要： Rules for the signaling and interpretation of chroma position are described. One rule, called the short rule, defines fifteen discrete chroma centering positions and corresponding four-bit syntax element. Another rule, called the extended rule, defines 81 discrete chroma centering positions and corresponding seven-bit syntax elements. A described method includes receiving digital media data at a digital media encoder, determining chroma position information for the received digital media data, and representing the chroma position information with one or more syntax elements in an encoded bitstream. The one or more syntax elements are operable to communicate the chroma position information to a digital media decoder. The chroma position information facilitates an image rotation or flip.

摘要： An apparatus for optimizing a virtual private network operates by defragmenting and deduplicating transfer of variable sized blocks. A large data object is converted to a plurality of data paragraphs by a fingerprinting method. Each data paragraph is cached and hashed. The hashes are transmitted between a primary and a satellite apparatus. Only data paragraphs which are not cached at both the primary and satellite are transferred. The data object is integrated from data paragraphs stored in cache and transmitted to its destination IP address.

摘要： A block transform-based digital media codec more efficiently encodes wide dynamic range transform coefficients in two parts: a normalized coefficient and bin address. The normalized coefficient relates to a grouping of coefficient values of the wide dynamic range into bins, whereas the bin address is an index of the coefficient value within a bin. With careful selection of the bin size, the normalized coefficients have a probability distribution more similar to narrow range transform coefficients, which is better suited to variable length entropy coding. The codec uses variable length entropy coding to encode the normalized coefficients in a “core” of the compressed bitstream, and fixed length coding to encode the bin address as a separate optional layer that can be omitted. The codec further adaptively varies the bin size of the grouping based on a backward adaptation process to adjust the normalized coefficients toward a probability distribution well suited for efficient variable length entropy coding.

摘要翻译： 基于块变换的数字媒体编解码器在两部分中更有效地编码宽动态范围变换系数：归一化系数和bin地址。 归一化系数与宽动态范围的系数值的分组相关，而bin地址是一个bin内系数值的索引。 通过仔细选择箱体尺寸，归一化系数具有更类似于窄范围变换系数的概率分布，其更适合于可变长度熵编码。 编解码器使用可变长度熵编码对压缩比特流的“核心”中的归一化系数进行编码，以及固定长度编码，以将bin地址编码为可以省略的单独的可选层。 编解码器进一步基于反向适应过程自适应地改变分组的二进制位尺寸，以将归一化系数朝向适合于有效可变长度熵编码的概率分布。

摘要： A fast implementation of the 8-point transform is realized using a sequence of butterfly operations and matrix multiplies. A fast implementation of the inverse transform is realized by applying inverses of the butterfly operations with the matrix multiplies in reverse flow. These fast implementations permit scaling to be incorporated into the transform stages either at the end of both dimensions of filtering, or separately at each stage. These fast implementations of the transform can be used in encoders and decoders based on this transform in image compression and other signal processing systems.
