摘要： One or more techniques and/or systems are disclosed for efficiently organizing images in a display. A size of an image is scaled by an image scale factor, while an aspect ratio for the image is maintained, where the image scale factor comprises a combination of a first scale distance and a second scale distance. The scaled image is filled into a first display line, if the size of the scaled image is not greater than an amount of display space remaining in the first display line; otherwise the scaled image is filled into a second display line. The image is expanded to mitigate white space in the display after the scaling, while maintaining the image's aspect ratio. This can be performed for a collection of images presented on a display to provide an enhanced user experience.

摘要： Described tools and techniques relate to signaling for DC coefficients at small quantization step sizes. The techniques and tools can be used in combination or independently. For example, a tool such as a video encoder or decoder processes a VLC that indicates a DC differential for a DC coefficient, a FLC that indicates a value refinement for the DC differential, and a third code that indicates the sign for the DC differential. Even with the small quantization step sizes, the tool uses a VLC table with DC differentials for DC coefficients above the small quantization step sizes. The FLCs for DC differentials have lengths that vary depending on quantization step size.

摘要： A block transform-based digital media codec efficiently compresses digital media data using block patterns representing whether a block's coefficients are zero-valued, such that their explicit encoding is skipped. Because the block patterns can have widely varying probability distributions, the codec adaptively chooses a prediction mode for modifying the block patterns (e.g., based on spatial prediction, or inverting) to enhance their compression using entropy coding techniques. Further, with high spatial correlation of block patterns, the codec encodes a meta block pattern for a region indicating whether all block patterns of the region represent zero-valued coefficient blocks. In such cases, the codec can then also omit explicitly encoding the block patterns in those regions.

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： A block transform-based digital media codec more efficiently encodes transform coefficients by jointly-coding non-zero coefficients along with succeeding runs of zero-value coefficients. When a non-zero coefficient is the last in its block, a last indicator is substituted for the run value in the symbol for that coefficient. Initial non-zero coefficients are indicated in a special symbol which jointly-codes the non-zero coefficient along with initial and subsequent runs of zeroes. The codec allows for multiple coding contexts by recognizing breaks in runs of non-zero coefficients and coding non-zero coefficients on either side of such a break separately. The codec also reduces code table size by indicating in each symbol whether a non-zero coefficient has absolute value greater than 1 and whether runs of zeros have positive value, and separately encodes the level of the coefficients and the length of the runs outside of the symbols.

摘要： A digital media codec adaptively re-arranges a coefficient scan order of transform coefficients in accordance with the local statistics of the digital media, so that the coefficients can be encoded more efficiently using entropy encoding. The adaptive scan ordering is applied causally at encoding and decoding to avoid explicitly signaling the scan order to the decoder in the compressed digital media stream. For computational efficiency, the adaptive scan order re-arranges the scan order by applying a conditional exchange operation on adjacently ordered coefficient locations via a single traversal of the scan order per update of the statistical analysis.

摘要： In certain embodiments, overlap operators are applied during encoding and/or decoding of digital media, where the overlap operators have reduced DC gain mismatch and/or DC leakage between interior overlap operators and overlap operators at the edge and/or corner. In other embodiments, information indicating a selected tile boundary option for overlap processing can be encoded and/or decoded. The selected tile boundary option indicates one of a hard tile boundary option and a soft tile boundary option for processing with overlap operators. Overlap transform processing can then be applied based at least in part on the selected tile boundary option.
