    Abstract: A system including an acceleration device including input circuitry configured, for each of a first plurality of video frames to be encoded, to receive an input including at least one raw video frame and at least one reference frame, and to divide each of the first plurality of video frames to be encoded into a second plurality of blocks, and similarity computation circuitry configured, for each one of the first plurality of video frame to be encoded: for each block of the second plurality of blocks, to produce a score of result blocks based on similarity of each block in each frame to be encoded to every block of the reference frame, an AC energy coefficient, and a displacement vector. Related apparatus and methods are also provided.

    IPC: H04J3/06

    Abstract: A device includes a receiver including a timestamp generator to update timestamps at a first rate. The receiver is to estimate a first time for receiving a signal, wherein the signal is associated with a synchronization operation. The receiver is further to receive the signal at a second time. The receiver is further to determine a difference between the second time and the first time, wherein the difference is associated with an error of the timestamp generator of the receiver. The receiver can also adjust the first rate to a second rate at which to update the timestamps by the timestamp generator, responsive to determining the difference between the first time and the second time.

    Abstract: In one embodiment, a clock synchronization system includes clock circuitry to maintain a clock running at a clock frequency, a clock controller, and a processor to execute software to generate clock update commands and provide the clock update commands to the clock controller, wherein the clock controller is configured to apply the clock update commands to the clock, store a holdover frequency command to maintain the clock during a failure of the clock update commands, apply the holdover frequency command to the clock responsively to detecting the failure.

    Abstract: Approaches in accordance with various illustrative embodiments provide for the determination and/or optimization the quality of an image or video, such as an image that has been compressed for transmission or storage then decompressed for presentation. Weights can be determined for a set of weight-based quality metrics to produce an overall quality metric that is a weighted combination of these metrics. Because different portions of an image or video frame may have different types of features, an image or video frame can be divided into blocks of pixels, for example, with different weights being assigned to different blocks using quality metrics. Different metrics can be considered as points in a high-dimensional weight space, with each dimension corresponding to a weight of a block. A combination of these points results in an improved quality metric. Compression settings can be updated based in part upon the overall quality metric values.
