Abstract: A motion detection method for detecting the difference in colors and an object position between a current frame and a previous frame through processing a composite video signal corresponding to both frames. The method includes: calculating a plurality of composite signal values included in the composite video signal to generate a calculation result; determining whether the calculation result conforms to a requirement to obtain a detecting result; and determining whether the colors and the object position are changed in two frames corresponding to the composite video signal according to the detecting result.

Abstract: A search method for a range search with a plurality of pre-set rules constructs a rule mapping table by dividing data associated with the rules into a plurality of sub-keys and generating output tables for each sub-key. A rule column is formed for a rule by following through each sub-key based on the associated range of data. A first output table for the first sub-key and upper and lower output tables are generated for each remaining sub-key. All the rule columns are arranged in parallel to form the rule mapping table. The method of search is accomplished by dividing an input data into a plurality of sub-keys and each sub-key is used to search through the rule mapping table for determining a rule that is satisfied with the input data. If multiple rules are satisfied, a priority encoder selects a highest priority rule as the search result.

Abstract: The present invention discloses a switching apparatus and method using bandwidth decomposition, appling a von Neumann algorithm, a Birkhoff theorem, a Packetized Generalized Processor Sharing algorithm, a water filling algorithm and a dynamnically calculating rate algorithm in packet switching of a high speed network.
