摘要： A method includes receiving a data unit, determining whether a current state, associated with a deterministic finite automata (DFA) that includes a portion of states in a bitmap and a remaining portion of states in a DFA table, is a bitmap state or not, and determining whether a value corresponding to the data unit is greater than a threshold value, when it is determined that the current state is not a bitmap state. The method further includes determining whether the current state is insensitive, when it is determined that the value corresponding to the data unit is greater than the threshold value, where insensitive means that each next state is a same state for the current state, and selecting a default state, as a next state for the current, when it is determined that the current state is insensitive.

摘要： Method and apparatus for selecting a reference frame for motion estimation in a video encoder is described. In one example, motion estimation is performed on a current macroblock in a current frame with respect to a reference frame to obtain a motion vector, a sum of absolute difference (SAD), a global motion vector, and an average SAD. A first relative change of the motion vector with respect to the global motion vector is computed. A second relative change of the SAD with respect to the average SAD is computed. A functional based on the first relative change, the second relative change, a first parameter, and a second parameter is computed. The functional is compared with a threshold. The reference frame is selected if the functional satisfies the threshold.
