摘要： A transcoder and methods of encoding inter-prediction frames of a downsampled video wherein the downsampled video is a spatially downsampled version of a full-resolution video. Full-resolution motion vectors are downscaled and each downscaled motion vector pinpoints a search area within a reference frame. The union or combination of search areas defines the search field for candidate motion vectors. A motion vector is selected from the candidates based on realizing a minimum rate-distortion cost.

摘要： An encoder for encoding a downsampled video in which macroblock partitioning is based upon downsampled partitioning of full-resolution macroblocks. The refinement of the downsampled partitioning involves storing the downsampled partitioning in a quad-tree data structure and recursively identifying and evaluating possible mergers of leaf nodes having a common parent node. Using rate-distortion analysis possible mergers are evaluated and advantageous mergers are performed, thereby creating larger partitions and new leaf nodes. The traversing of the quad-tree to identify possible leaf node mergers is stopped when no further possible mergers may be identified that would result in a rate-distortion advantage.

摘要： An encoder for encoding a video by performing motion estimation using predicted residuals in the rate-distortion cost expression. The predicted residuals are determined by finding a predicted motion vector with respect to the original reference frame and calculating the corresponding residual values. The actual motion vector is then selected based on minimization of the rate-distortion cost expression with respect to the reconstructed reference frame, where the rate-distortion cost expression includes the predicted residuals. In particular, the cost expression includes reconstructed predicted residuals within the distortion term.
