Style-sheets Extraction from Existing Digital Contents by Image Processing for Web-Based BML Contents Management System

This paper proposes a web-based BML contents management system. BML is the short form of Broadcast Markup Language which is a script language for data broadcasting contents included in digital TV broadcasting services of Japan. The scripting style of BML is very similar to that of HTML and it also supports style-sheets and JavaScript. However, in BML, there are many restrictions about the display area size, font sizes, color types and so on because the BML-browser of TV is not flexible as compared with the Web-browser. Although there are a couple of dedicated software packages for BML contents creation, they are very expensive and difficult to use. So, BML contents creation is not easy for the end-user. To make it easier to create BML contents, the authors have been developing a Web-based BML contents management system. This paper explains fundamental functionalities provided by the proposed BML contents management system. Already many digital contents were created and stored and we can easily obtain their images by capturing the screen snapshot. So, this paper also proposes style-sheets extraction method for BML contents from such already existing digital contents by image processing techniques.
