摘要： Low complexity method embodiments directly decode low-resolution frames from compressed high-resolution videos that were encoded using predictive coding techniques like the H.264 video coding standard. The smaller the decoding resolution, the higher will be the computation and power savings of using the method. Low-frequency coefficients of 2D transformed predictions are added to the low-frequency coefficients of the transformed residual error. Low-frequency coefficients of the reconstructed data are then inverse transformed taking a smaller size transform. Further savings are obtained by reconstructing only those reference pixels that will be needed for accurate decoding of further Intra blocks.

摘要： Systems and methods for reducing interference caused by leakage of signals generated by a spread spectrum phase lock loop (SS PLL). The system and method uses a sinusoidal spreading signal to spread the output of a SS PLL. A notch filter tracks the frequency of the output of the SS PLL to steer the notch in the filter to the instantaneous frequency output from the SS PLL, thus allowing the notch filter to be placed in the path of signals that have unwanted leakage from the SS PLL.
