Software compatibility and human interface for DV over IP

We created a high quality video transportation system for broadband networks, using DV (digital video) format. Our implementation was named DVTS (Digital Video Transport System). DVTS supports FreeBSD, NetBSD, Linux, MacOSX, and Windows operating systems. Each operating system has a different interface to interact with an application. For example, MacOS uses a GUI (graphical user interface) to allow end users to run applications with simple mouse and keyboard operation. We have ported DVTS to the MacOSX platform. MacOSX Aqua is an abstraction of a human interface based on a GUI. However, since the MacOSX implementation for the former DVTS is implemented using a CUI (character user interface), it does not assimilate with the MacOSX Aqua abstraction. Additionally, the video playback window for the DVTS receiver is designed with the QuickTime framework in our new system. Abstraction and implementation of DVTS for the Aqua interface is proposed. Due to this research, the usability of DVTS is enhanced.
