    摘要： An input frame to be motion compensated is partitioned into smaller blocks of pixel data. First, motion estimation is performed on each block in full-pixel resolution. Then, full-pixel resolution motion vector is refined to half-pixel accuracy by searching the surrounding half-pixel resolution blocks in vertical and horizontal positions with respect to the full-pixel resolution motion vector. An absolute magnitude of a horizontal component of the full-pixel resolution motion vector is examined to see if it is greater or less than a predetermined threshold to detect any significant movement. If the horizontal component absolute magnitude is less than the threshold, a frame-based interpolation will be used for forming the sub-pixel resolution block. If the horizontal component absolute magnitude is greater than the threshold, a field-based interpolation will be used instead. The sub-pixel resolution block is subjected to motion estimation and compensation to obtain a predicted block which will then be coded to obtain a coded bit stream.

    摘要： An apparatus, method, and computer program encode video information. The apparatus, method, and computer program use a global deviation for previously encoded video information to encode additional video information. The global deviation represents a difference between (1) at least one expected characteristic of the previously encoded video information if encoded at a target bit-rate and (2) at least one actual characteristic of the previously encoded video information. The apparatus, method, and computer program use the global deviation to adjust at least one encoding parameter, which is then used to encode the additional video information.

    摘要： A macro-block (MB) quantization reactivity compensation method for a video encoder is provided. The method calculates a reference picture quantization value based on a calculated picture complexity. This predicted reference quantization is combined with the bits-used reactive MB reference quantization value to determine the final MB reference quantization value. This MB reference quantization value is also made adaptive to the VBV buffer fullness, as well as to the predicted change of the current picture complexity. A video encoder and an article of manufacture that comprises computer readable program code for execution of the method are also provided.

    摘要： A method of selecting a motion vector for use in a motion estimation system in which the motion vector defines movement of a block of pixels between a search window and a reference frame. The method includes the steps of scanning a search window in a fixed order for a suitable match with an area of the reference frame such that each search position within a current row or column of the window is one pixel away from a previous search position, defining a preferred point in the search window, calculating a primary norm function with reference to the preferred point for a given position in each row or column, calculating a norm function for each search position based on a linear increment of the primary norm function for the respective row or column, calculating an Absolute Error (AE) for each search position, based on a difference between a given property of the search position and a position in the reference window, and selecting a motion vector, the displacement of the motion vector defined in terms of the search position having the smallest AE and the smallest norm function. An apparatus for performing the method is also disclosed.
