摘要

The present invention relates to real time recording of working screen and audio signal, replay method and the system. The present invention comprises real time recording process and replay process. The recording process comprises the steps of capturing capture region of the information processing apparatus screen in real time to record as an image file; recording a first audio signal inputted to the information processing device through a sound input device and a second audio signal generated in the information processing apparatus; and monitoring input of an event through a user interface device, and if an event is inputted, saving event information of the inputted event as an event file. The replay process comprises the steps of deriving time information off each moving picture frame from the moving picture file; deriving time information of each event from the event file; Synchronizing each event with the corresponding moving picture frame by comparing the time information of each moving picture frame with the time information of each event; and replaying the synchronized event and moving picture frame. According to the present invention, multimedia data including screen on the terminal, audio signal and the event can be recorded and replayed simultaneously in real time with simple process.
