    摘要： A video processing system may be operable to utilize multi-band sharpening to process luma signals for image signals. The luma signal may be decomposed into a plurality of frequency band components, wherein each component may be processed separately using different sharpening gains and/or offsets. The multi-band processed components may be combined to generate sharpened output luma signals. The multi-band sharpening may be performed utilizing peaking processing, and the input luma signal and/or LTI sharpened luma signals may be combined with the multi-band peaking sharpened signals to generate the sharpened output luma signals. Corresponding chroma signals may also be adjusted to generate sharpened output chroma signals. Luma and/or chroma sharpening operations may be further adjusted based on coring, clipping avoidance, luma statistics, color region detections, and/or curve control parameters. Sharpened output image signals may be generated based on the sharpened output luma signals and the sharpened output chroma signals.

    摘要： A video processing system may be operable to utilize one-dimensional (1-D) piecewise linear (PWL) functions to adjust chroma and/or luma parameters corresponding to pixels that are determined to fall within one or more N-dimensional color adjustment regions in spatial representation of pixels' chroma and luma information. The chroma and/or luma parameters comprise Y, Cb, Cr, saturation and/or hue parameters in systems using Y′CbCr color coding. The 1-D PWL functions are operable to generate adjustment data corresponding to one of chroma and/or luma parameters, wherein the adjustment data comprise offset or gain data. The 1-D PWL functions are reprogrammable. The 1-D PWL functions may enable smooth transitions in boundary areas of at least some of the N-dimensional color adjustment regions. Determination of whether pixels fall within the color adjustment regions is based on a plurality of boundary points and/or criteria. Adjustment data corresponding to overlapped regions are aggregated.

    摘要： A system and method are disclosed for performing digital multi-channel decoding of a BTSC composite audio signal. Each subsequent stage of the digital multi-channel decoding process is performed at the lowest sampling rate that yields acceptable performance for that stage. Analog-to-digital conversion of the composite audio signal is performed first to generate a composite digital audio signal. After analog-to-digital conversion, all signal processing may be performed in the digital domain. The composite digital audio signal is digitally filtered to frequency compensate for variations caused by previous stages of processing, including IF demodulation. Digital channel demodulation and filtering are performed to isolate single channels of the composite digital audio signal such as SAP, L−R, and L+R channels. SAP and L−R channels are DBX decoded resulting in corresponding decoded signals using a unique combination of digital filters that are an efficient translation of a corresponding combination of analog filters. The decoded L−R channel and the L+R channel are re-matrixed to form left and right stereo signals. Any of the SAP signal, left and right stereo signals, and L+R channel signal may be sample rate converted and output at a standard audio output rate.

    摘要： Certain aspects of a method and system for multi-channel PCM audio grouping in hardware are disclosed. Aspects of one method may include arbitrating the processing of a plurality of channel pairs within a channel group based on a plurality of received PCM audio samples. The plurality of channel pairs within the channel group may be sequentially processed based on their channel IDs. The channel ID of the first channel pair within the channel group may be allocated as a common group identification value. The grouping of multiple channel pairs ensures channel synchronization.

    摘要： The methods provided use external fields such as light and electricity as a means of directing the crystallization of concentrated colloidal systems. Not only can nucleation be directed, crystal melting can be carefully controlled and light-induced crystal diffraction used as a means of directing light propagation. A number of factors play a significant role on the crystallization rate and location, including the intensity of the light field, the magnitude of the electric field, the colloid concentration, the colloid size, and the colloid composition. In varying these parameters, kinetics in these processes are extremely fast when compared to traditional colloidal crystallization approaches.
