    • Methods and systems for processing chroma signals are disclosed. Aspects of one method may include compensating a modulated chroma signal for distortions due to audio trap filtering. The compensated chroma signal may be demodulated to generate U and V chroma signals. The U and V chroma signals may be low pass filtered, and then YC aligned. YC alignment may comprise correcting portions of the U and V chroma signals based on the luma signal. The correction may be based on, for example, correlation between the U and V chroma signals and the Y luma signal, and/or energy level of the Y luma signal. The corrected U and V chroma signals may be chroma sharpened, where a gain parameter may be changed to change a transition slope for the U and V chroma signals. The chroma sharpened signals may also be clamped to reduce overshoot and undershoot.
    • 公开了用于处理色度信号的方法和系统。 一种方法的方面可以包括补偿由于音频陷波滤波引起的失真的调制色度信号。 补偿色度信号可被解调以产生U和V色度信号。 U和V色度信号可以低通滤波,然后YC对齐。 YC对准可以包括基于亮度信号校正U和V色度信号的部分。 校正可以基于例如U和V色度信号与Y亮度信号之间的相关性和/或Y亮度信号的能级。 校正的U和V色度信号可以是色度锐化的,其中可以改变增益参数以改变U和V色度信号的转变斜率。 色度锐化的信号也可以被钳位以减少过冲和下冲。

    • Herein described is a system and method for improving the appearance of video by generating an improved 4:2:2 chroma. The system comprises a 4:2:2 to 4:2:0 chroma regenerator that regenerates 4:2:0 chroma given a received 4:2:2 chroma, and a 4:2:0 to 4:2:2 chroma generator that weaves and interpolates the regenerated 4:2:0 chroma to yield an adjusted 4:2:2 chroma. The system further comprises a blending system used for blending the adjusted 4:2:2 chroma with the received 4:2:2 chroma based on a control input provided by a motion indication signal. The method comprises regenerating a 4:2:0 chroma from a received 4:2:2 chroma using an algorithm. The method further comprises generating an adjusted 4:2:2 chroma using the regenerated 4:2:0 chroma using another algorithm. The method further comprises blending the adjusted 4:2:2 chroma with the received 4:2:2 chroma to generate an improved 4:2:2 chroma.

    • Certain embodiments of the invention may be found in a method and system for automatic aspect ratio detection and may comprise scanning lines in at least a selected portion of an image and locating a first reference pixel in one of the scanned lines. A corresponding sliding sum and a sliding number may be generated starting from the first reference pixel and a white edge determined based on the generated sliding sum and/or the generated sliding number. The first reference pixel may be a non-black pixel and a value which corresponds to and defines non-black may be variably defined. The sliding sum and the sliding number may utilize m bins, where m is greater than one (1). A luma sum threshold may be compared with the generated sliding sum to locate the white edge for aspect ratio detection.

    • A video processing system may implement a video scaling algorithm using interpolation based on polyphase filtering. A video or graphics scaler may be utilized to scale luma, chroma, and/or alpha information in a video image. The scaler may comprise a first polyphase sub-filtering with zero phase shift that generates an in-phase filtered output from an input video image and a second polyphase sub-filtering that generates an out-of-phase filtered output from the input video image. The video scaler may also comprise an interpolator that may generate a scaled video image based on the generated in-phase and out-of-phase filtered outputs and a scaling factor. The scaling factor may be determined based on an input video size (M) and a desired output video size (N). The interpolation of the generated in-phase and out-of-phase filtered outputs in the video scaler may be implemented by utilizing a Farrow structure.
