摘要

This paper proposes a web-based BML contentsmanagement system. BML is the short form of BroadcastMarkup Language which is a script language for databroadcasting contents included in digital TV broadcastingservices of Japan. The scripting style of BML is very similar tothat of HTML and it also supports style-sheets and JavaScript.However, in BML, there are many restrictions about thedisplay area size, font sizes, color types and so on because theBML-browser of TV is not flexible as compared with the Webbrowser.Although there are a couple of dedicated softwarepackages for BML contents creation, they are very expensiveand difficult to use. So, BML contents creation is not easy forthe end-user. To make it easier to create BML contents, theauthors have been developing a webbased BML contentsmanagement system. This paper explains fundamentalfunctionalities provided by the proposed BML contentsmanagement system.Already many digital contents were created and stored andwe can easily obtain their images by capturing the screensnapshot. So, this paper also proposes style-sheets extractionmethod for BML contents from such already existing digitalcontents by image processing techniques.
