New-media document (NewDoc) and dynamic navigation on the BTRON specification

The authors discuss how to handle multimedia documents including video data. The multimedia document is called NewDoc, which stands for new-media document. Two important features are discussed. One is the handling of the video data. The other is the navigation method, which can be applied to the video data, whose contents vary with time. This navigation method is called dynamic navigation. For editing the NewDoc, NewDE (New-media document editor) has been designed. NewDE has been implemented on the BTRON specification operating system with the video manager, which is part of the external kernel and is able to handle the video data. >
