Abstract: A method for handling network jitter is provided. The method includes: receiving a plurality of data packets and recording a receiving time of each data packet; calculating time intervals between all adjacent data packets according to the receiving time of each data packet; identifying a probability distribution of the time intervals according to a plurality of preset intervals; calculating a target size of a buffer according to the probability distribution and an allowable jitter probability; and adjusting the buffer according to the target size of the buffer.

Abstract: The present invention discloses a method and an apparatus for earphone sound effect compensation and an earphone. The method of the present invention comprises: obtaining monitored signal data in a current wearing state of an earphone user according to a signal collected by a monitoring microphone and an audio signal played by a loudspeaker of the earphone; computing error data of the monitored signal data in the current wearing state relative to standard signal data in a standard wearing state of the earphone; and performing sound effect compensation to the earphone according to the error data. The technical solution of the present invention adopts an adaptive digital signal processing manner, which can dynamically compensate for sound effects in different earphone wearing manners and enable an earphone user to appreciate an audible effect in a standard earphone wearing state.

Abstract: An activity diagram model-based system behavior simulation method. First, a to-be-simulated unified modeling language activity diagram model is read and parsed, and extracted therefrom is important model element information, and a complete model mapping is constructed in a memory; then, the unified modeling language activity diagram model that is read is parsed, and various model elements respectively are parsed from the unified modeling language activity diagram model; then, a hybrid execution concept is combined and employed for continued specific execution, symbolic execution, and constraint solving, and the process is terminated insofar that a node coverage threshold is reached; and finally, simulated use cases collected in the preceding step is used for simulated execution of the unified modeling language activity diagram model.
