  • METHOD AND APPARATUS FOR ENCODING INSTANTANEOUS DECODER REFRESH UNITS
    Publication number: 20160119619
    Abstract: Method and apparatus for encoding instantaneous decoder refresh (IDR) units are disclosed. The method includes partially encoding an IDR block as a non-IDR block, decoding the partially encoded IDF block to generate a reconstructed IDR block and fully encoding the reconstructed IDF block as an IDR block. In a first pass, an IDR unit is partially encoded (no entropy encoding) using regular encoding parameters of a non-IDR unit in the same picture. The partially-encoded IDR unit is then inverse quantized and inverse transformed to generate a reconstructed video data of the IDR unit. In the second pass, the reconstructed video data of the IDR unit is passed as an input to the prediction module and fully encoded using the IDR settings. The reconstructed IDR unit may be encoded with very high fidelity.

  • Power management in multi-stream audio/video devices
    Patent number: 9325929
    Abstract: A method of managing power consumption in a video device capable of displaying encoded multi-stream video is disclosed. Power reduction is achieved by limiting the amount of video and audio decoding and processing performed on at least some of the encoded streams, by taking particular application contexts into account. In a normal power consumption mode, audio/video data from all streams are decoded and digitally processed for output. In response to detecting a reduced power consumption mode, audio/video from at least some of the streams are processed in a modified manner to reduce power consumption.

    Patent number: 9304772
    Abstract: A system and method is provided for improving efficiency, power, and bandwidth consumption in parallel processing. Rather than requiring memory polling to ensure ordered execution of processes or threads in wavefronts, the techniques disclosed herein provide a system and method to allow any process or thread in a wavefront to run out of order as long as needed, but ensure ordered execution of multiple ordered instructions when needed. These operations are handled efficiently in hardware, but are flexible enough to be implemented in all manner of programming models.

  • Adaptive frequency domain filtering for phase plane correlation
    Patent number: 9300966
    Abstract: In a Phase Plane Correlation (PPC) process, using adaptive frequency domain filtering to aid in generating candidate motion vectors. It is determined when it is beneficial to pre-filter an input image, prior to a PPC process. This results in more reliable and consistent PPC surfaces than otherwise. The filter is applied in the frequency domain where time-domain convolution becomes a much more efficient component-wise multiplication with an in-place window. An energy measure of the high-frequency content in the computed Fourier surfaces gauges the degree of high frequency content in the image. First, the Fourier transform of the two images is computed. Then, the high-frequency content is estimated from the Fourier surfaces. A window function is computed as a function of the high-frequency energy. The window is applied to the Fourier surfaces. Then, the modified Fourier surfaces are fed into the PPC process.

  • Adjusting a data rate of a digital audio stream based on dynamically determined audio playback system capabilities
    Patent number: 9286904
    Abstract: A computing device may be configured to output a digital audio stream to an audio playback system for rendering as sound over speakers. The sound may be sampled. Based at least in part on a quality of the sampled sound, the data rate of the digital audio stream may be reduced by reducing a sampling rate and/or by reducing a number of bits per sample. A reduced sampling rate may be determined based on a computed maximum sampling rate of the audio playback system, and/or a reduced number of bits per sample may be determined based on a computed maximum number of bits per sample of the audio playback system. The maximum usable sampling rate and maximum usable number of bits per sample may be determined based on an upper usable frequency within a frequency spectrum of the sampled sound.
