Abstract: Watermark data is converted to watermark coefficients, which may be embedded in an image by converting the image to a frequency domain, embedding the watermark in image coefficients corresponding to medium-frequency components, and converting the modified coefficients to the spatial domain. The watermark data is extracted from the modified image by converting the modified image to a frequency domain, extracting the watermark coefficients from the image coefficients, and determining the watermark data from the watermark coefficients. The watermark data may be truncated image data bits such as truncated least significant data bits. After extraction from the watermark, the truncated image data bits may be combined with data bits representing the original image to increase the bit depth of the image. Watermark data may include audio data portions corresponding to a video frame, reference frames temporally proximate to a video frame, high-frequency content, sensor calibration information, or other image data.

Abstract: A video encoder performs multiple coding passes on coefficients in a coefficient block. During each coding pass, the video encoder encodes a different set of syntax elements for coefficients in the coefficient block. A video decoder uses the syntax elements for a coefficient to determine the value of the coefficient. When the video encoder performs a coding pass, the video encoder selects a coding context for a syntax element based at least in part on a syntax element generated in an earlier coding pass for a non-causal coefficient and based at least in part on a value of a syntax element generated during the current coding pass for a causal coefficient. The video encoder entropy encodes the syntax element based on the selected coding context. A video decoder performs a similar series of coding passes in which the video decoder selects coding contexts and entropy decodes the syntax elements.

Abstract: An encoding/transmitting apparatus that is used to transmit moving-picture data from a transmitting side to a receiving side through a transmission path and to subject the moving-picture data to streaming in the receiving side has an external-output request determining unit that monitors the state of a network. If the network assumes an undesirable state, the request determining unit causes a multiplex output unit to stop multiplexing data. When the network assumes a desirable state, the multiplex unit starts multiplexing the data again.

When the area occupied by encoded data in an encoded-video-data storage unit and the area occupied by encoded data in an encoded-audio-data storage unit exceed a predetermined value, the encoding units stop encoding data, and wait until the area occupied by encoded data sufficiently decreases.

Abstract: The complexity of sparse code multiple access (SCMA) decoding can be reduced by pruning codebooks to remove unlikely codewords prior to, or while, performing an iterative message passing algorithm (MPA). The pruned codebook is then used by to perform one or more iterations of MPA processing, thereby reducing the number codeword probabilities that are calculated for the corresponding SCMA layer.

The pruned codebook may be “reset” by reinserting the pruned codewords into the codebook after a final hard-decision for a given set of received samples is made, so that the pruning does not affect evaluation of the next set of samples.

Abstract: In various respects, hardware-accelerated decoding is adapted for decoding of video that has been encoded using scalable video coding. For example, for a given picture to be decoded, a host decoder determines whether a corresponding base picture will be stored for use as a reference picture.

The host decoder repeats the process layer-after-layer in the order that layers appear in the bitstream, according to a defined call pattern for an acceleration interface, which helps the accelerator determine the layers with which buffers are associated.

Abstract: Computationally efficient algorithms may be applied for fast dictionary learning solving the convolutional sparse coding problem in the Fourier domain. More specifically, efficient convolutional sparse coding may be derived within an alternating direction method of multipliers (ADMM) framework that utilizes fast Fourier transforms (FFT) to solve the main linear system in the frequency domain. Such algorithms may enable a significant reduction in computational cost over conventional approaches by implementing a linear solver for the most critical and computationally expensive component of the conventional iterative algorithm. The theoretical computational cost of the algorithm may be reduced from O(M3N) to O(MN log N), where N is the dimensionality of the data and M is the number of elements in the dictionary. This significant improvement in efficiency may greatly increase the range of problems that can practically be addressed via convolutional sparse representations.
