摘要： 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.

摘要： 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.
