摘要： A system and method for controlling a media player for replacement content, such as dynamic ad insertion. The system tracks video watermarks from a content stream, where the input content timeline is being modified by a user exercising the transport controls of a digital video recorder (DVR). A Detector Engine receives decoded video frames and extracts a time-offset field, a VP1 payload, and a Cyclic Redundance Check (CRC) field in each video frame. A Content Timeline Tracker monitors and analyzes the output of the Detector Engine to produce a piecewise linear approximation of the content timeline, wherein playback rate changes by a user in an upstream device can be tracked. This enables the playback of auxiliary content which is synchronized to a watermark timeline recovered from the received content in cases where the recovered timeline has a non-linear mapping to real time. When the estimated speed is changing due to user-controlled trick play of recorded content, estimated speed deviates from the user intended speed profile because of imperfect playback of the media player. The system includes additional filtering of estimated speed to produce a Boolean updated speed which is asserted sparsely at estimated control segment endpoints in an attempt to delineate constant slope (constant speed) control segments.

摘要： The embodiments of the present application provide a polar code construction method and apparatus, which relate to the field of communications technology. The method comprises: obtaining a polar weight spectrum for each polarized channel; calculating an upper bound of error probability of each polarized channel based on the obtained polar weight spectrum, distribution probability density of a fading factor of a fading channel, and a signal-to-noise ratio of the fading channel; taking a logarithm of the calculated upper bound of the error probability for each polarized channel and obtaining a reliability metric of the polarized channel based on the taken logarithm, wherein the smaller the metric value is, the higher the reliability of the polarized channel is; sorting all polarized channels in an ascending order of the reliability metric and selecting part of the polarized channels having a lowest reliability metric for transmitting information bits and the remaining polarized channels for transmitting frozen bits. According to the embodiments of the present application, performing polar code construction under the condition of a fading channel can improve the efficiency of polar code construction.

摘要： Described are methods and circuits for margin testing digital receivers. These methods and circuits prevent margins from collapsing in response to erroneously received data and can thus be used in receivers that employ historical data to reduce intersymbol interference (ISI). Some embodiments detect receive errors for input data streams of unknown patterns and can thus be used for in-system margin testing. Such systems can be adapted to dynamically alter system parameters during device operation to maintain adequate margins despite fluctuations in the system noise environment due to e.g. temperature and supply-voltage changes. Also described are methods of plotting and interpreting filtered and unfiltered error data generated by the disclosed methods and circuits. Some embodiments filter error data to facilitate pattern-specific margin testing.

摘要： Methods, systems, and apparatus for parallel optimization of continuously running quantum error correction by closed-loop feedback. In one aspect, a method includes continuously and effectively optimizing qubit performance in-situ whilst an error correction operation on the quantum system is running. The method directly monitors the output from error detection and provides this information as feedback to calibrate the quantum gates associated with the quantum system. In some implementations, the physical qubits are spatially partitioned into one or more independent hardware patterns, where the errors attributable to each hardware pattern are non-overlapping. The one or more different sets of hardware patterns are then temporarily interleaved such that all physical qubits and operations are optimized. The method allows for the optimization of each section of a hardware pattern to be performed individually and in parallel, and can result is O(1) scaling.

摘要： An apparatus, such as a memory (e.g., a NAND memory), can have a controller, a volatile counter coupled to the controller, and a non-volatile memory array coupled to the controller. The controller can be configured to write information, other than a count of the counter, in the array each time the count of the counter has been incremented by a particular number of increments. Counts can be monotonic, non-volatile, and power-loss tolerant.
