摘要： The present invention provides an apparatus and method for providing a programmable inverse discrete cosine transform, wherein the transform coefficients are loaded into a memory area of a core transform device and a variety of coding standards can thereby be handled by the same programmable core device. The core device is configured to process a certain sized data block, and the incoming source blocks are converted to conform to this size. After transformation, the proper sized result can be extracted from the transform device output. A switchable speed-up mode provides for 4-point transforms, rather than 8-point transforms. Alternatively, the invention also provides for dedicated transform hardware to be switchably used in conjunction with programmable transform hardware, depending upon the type of coding being used, and the speed of inverse transform desired.

摘要： A method and apparatus are disclosed for performing motion estimation and compensation to fractional pixel accuracy using polyphase prediction filters as part of a video compression/decompression technique. A motion estimator applies a set of polyphase filters to some data in the reference picture and generates motion vectors, an estimated macroblock of video data, and a residual error macroblock of video data. The data referenced in the reference picture usually have more data than a macroblock since multi-tap filtering needs to access more data. A motion compensator generates a compensated macroblock of video data in response to the reference video data, the residual error macroblock of video data, and a polyphase prediction filter decided by the motion vector. The reference video data are usually reconstructed at the compensator side.

摘要： A video and graphics system provides square graphics pixels to blend images having 640×480 pixels, such as graphics images provided by some set top boxes and intended to be displayed at a 12.27 MHz display sample rate, with images having 704×480 pixels, such as ITU-R 601 compliant images such as NTSC SDTV images, having oblong pixels and displayed at a 13.5 MHz display sample rate. A sample rate converter including a multi-phase-multi-tap filter is used to generate square pixels. The multi-phase-multi-tap filter provides a good balance of sharpness, smoothness, anti-aliasing and reduced ringing. The multi-phase-multi-tap filter can also be used to convert images having 320×480 pixels to images having 704×480 pixels. The multi-tap filter can be used for scan rate conversion of graphics or video images for HDTV or SDTV applications.

摘要： A method and system for content adaptive analog video noise detection are provided. A motion metric (MM) value, an edge detection value, and a content detection value may be determined for pixels in a video image. The MM values of pixels with edge detection values smaller than an edge threshold value and with content detection values smaller than a content threshold value may be collected and accumulated for a portion of the noise level intervals when the MM values fall in this interval. The MM values collected and accumulated may be utilized to determine an average noise level for each of the intervals. A noise level indicator (NLI) for the current video image may be determined based on the noise level of the current image or on the noise levels of the current and at least one previous video images.

摘要： A system and method for determining whether to process a signal using three-dimensional comb filtering. Various aspects of the present invention may comprise method steps and system components that generate an inter-frame chroma signal. Various aspects may generate a filtered inter-frame chroma signal by removing a band of frequency components from the inter-frame chroma signal that generally corresponds to chroma signal components. Various aspects may analyze the filtered inter-frame chroma signal to determine whether three-dimensional comb filtering may be appropriate. Various aspects may comprise method steps and components that generate inter-frame and intra-frame luma signals. Various aspects may generate filtered inter-frame and intra-frame luma signals by removing frequency components from the inter-frame and intra-frame luma signals, respectively, that fall outside a frequency band near the chroma sub-carrier frequency. Various aspects may analyze the filtered inter-frame and intra-frame luma signals to determine whether three-dimensional comb filtering may be appropriate.

摘要： A system and method that support both progressive and interlaced format video transmission and display. The system utilizes de-interlacing techniques to convert input interlaced format video to progressive format video, and compress and vertically scale the progressive format video to communicate videos more efficiently in a progressive format. The system also supports interlaced and progressive displays, where after decompressing and vertically resealing the communicated compressed progressive format video, the video may be converted to interlaced format if the display supports interlaced format video. The system is capable of dynamically switching between the progressive and the interlaced format modes.

摘要： A wave power generation unit suitable for large-scale application and a system thereof are disclosed. The wave power generation unit includes at least two types of water platforms that dynamically differ from each other under the effect of waves: stationary floating platform and movable floating platform. The two types of floating platforms are paired to form a functional unit, and the difference between the two floating platforms caused by waves causes interactions between the two floating platforms. The movable floating platform converts wave energy into mechanical energy, and the stationary floating platform converts machinery energy into electrical energy. The dynamic features of the floating platform are adjusted by a sink and float control device or a peripheral lifting device, and the adjustment effect is enhanced by a large-mass flywheel. Multiple wave power generation units form a wave power generation system.
