The embodiments herein relate to multi pattern searching and, more particularly, to multi pattern search or multi pattern matching using logic content processing. The input pattern is type cast to a Boolean alphabet and is then processed to create a corresponding signature set. Further, the signature set is divided into subsets and a Boolean logic function representing each signature subset is created. Further, the values of each subset are simultaneously compared with windows of an input data steam or data file to find a match. If a match is found, the system returns a hit, else a miss. Parallel stages may be added to enhance performance of the system, as multiple inputs may be processed at a time.

A method and apparatus for determining the quality of a block match for a candidate motion vector in a video encoder system using motion vectors representing the difference in coordinates of a macroblock of data in a current frame of video data and coordinates of a related macroblock of data in a reference frame of video data. The method can include defining a search pattern, searching a region based on the search pattern for a candidate motion vector for evaluation, calculating a difference metric, calculating a bias based on the difference between a predictor motion vector and a candidate motion vector, determining a modified difference metric by adding the difference metric to the bias, and defining a final motion vector based on the modified difference metric.

The invention provides a quick inter-frame prediction mode selection method for AVS-M video coding. Algorithms can be classified according to the distribution situation of inter-frame coding modes and are arranged according to processing priority, different types are judged sequentially, possible modes are compared selectively, and the number of modes to be judged is reduced. Early termination judgment is utilized to carry out priority judgment on an SKIP mode, and whether other modes are early termination is judged through threshold value judgment. If threshold value judgment conditions are met, the SKIP mode is directly utilized to code. If the threshold value judgment conditions are not met, an Inter4*4 mode, an Inter 8*8 mode and an Inter 16*16 mode are used as initial modes. A part of macro block modes are removed according to whether rate-distortion cost meets monotony, and accordingly useless block mode search processes are reduced. Compared with a full-mode selection algorithm, the calculating times is reduced by 52.5% to 85.8%, and the calculating complexity of inter-frame forecasting modules is reduced.
