Abstract
A real-time screen recording system is disclosed. Under the design of the real-time screen recording system of this invention, the Event Inspector records updated regions of the screen when a windows update event is generated, the Periodical Extractor records the screen updates periodically. This mechanism ensures that all updates will be recorded. The Event Filter inspects the update events to identify events relating to updates of screen to ensure correct recording of the updated regions. The Sporadic Controller adjusts the working frequency of the Periodical Extractor, so that the Periodical Extractor operates in an efficient manner. The Update Region Filter filters out unnecessary updated regions to avoid heavy workload of the computer system. As a result, an efficient and correct screen recording system may be achieved.
