摘要： While maintaining a high degree of freedom in choosing partition sizes and transformation sizes adapted for local characteristics of videos, the amount of metadata is decreased. A video encoding apparatus (10) divides an input video into blocks of a prescribed size and encodes the video block by block. The video encoding apparatus is provided with: a prediction parameter determining portion (102) that decides the block partition structure; a predictive image producing portion (103) that generates predictive images, partition by partition, as prescribed by the partition structure; a transform coefficient producing portion (107) which applies one of the frequency transformations included in a prescribed transformation preset to prediction residuals, i.e. the differences between predictive images and the input video; a transform restriction deriving portion (104) which generates the list of transform candidate, i.e. lists of frequency transformations that can be applied to each partition, on the basis of partition format information; and a variable-length-encoding portion (108) which, on the basis of the list of transform candidate and the transformation preset, performs variable-length encoding on transformation selection flags.

摘要： Methods and apparatus for conducting motion searching are provided. Motion search is conducted by comparing an image macroblock against a plurality of positions within an image search region. A first 2D array comprises interconnected multi-directional shift registers for storing and shifting image values corresponding to a search window within the search region. A second 2D array comprises registers for storing image values corresponding to a macroblock. A distortion calculation module is operatively connected to the first and second 2D arrays, the distortion calculation module being arranged to calculate and output a distortion value corresponding to the difference between image values stored in associated registers of the first and second arrays, the distortion value thereby quantifying the correlation between the search window and the macroblock. The shift registers of the first 2D array are controlled to pass image values between adjacent shift registers to translate the position of the search window within the search region. Distortion values outputted after progressive shifts of the first 2D array are then tracked thereby determining an optimal registration position of the macroblock relative to the search region.
