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 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 rescaling 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 system and method for decoding a digital video data stream. In one aspect, a plurality of hardware acceleration modules are used together with a core processor. The accelerators operate in a decoding pipeline wherein, in any given stage, each accelerator operates on a particular macroblock of video data. In the subsequent pipeline stage, each accelerator works on the next macroblock in the data stream, which was worked on by another one of the accelerators in the previous stage. The core processor polls all of the accelerators during each stage. When all accelerators finish their tasks for a given stage, the core processor initiates the next stage. In another aspect, two variable-length decoders are employed to simultaneously decode two macroblock rows of a video frame. Each variable-length decoder works to decode an assigned row and the rows are variable-length decoded in parallel. The variable-length decoders operate as part of a pipeline wherein the variable-length decoders alternate, stage-by-stage, decoding macroblocks.
