Abstract

As the multimedia technology has become in popular, many software packages that are for using those multimedia contents have also been developed. Directshow is a media framework which makes the development of such multimedia software simple, quick and regular process. In the Directshow, data are processed through the connections between filters. In general, Filtergraph is utilized to be set as 'Intelligent Connection' for filter connection. However, when we use this 'Intelligent Connection' option, they can show non-expected results or fail to connect with filter's pins together. So in this paper, we propose non-necessary filter cut-off method for connecting only just wanted filters. There are two methods such as inner filter cut-off method and outer filter one. The inner filter cut-off method is good at connection's compatibility and able to quickly connect with each other filter. But in the outer filter cut-off method, filter source is not necessary and connection is exactly done with other filter. In the end, we propose Directshow based filter cut-off model which compose of wanted filter connection and minimize error probability, through mixing up the advantages of two filter cut-off methods.
