DVTS(Digital Video Transport System) Consortium
* This laboratory has been completed.
Our consortium aims to expand DVTS (Digital Video Transport System) in cooperation with industry. This high-definition video distribution system is the result of research from the WIDE Project. This system would provide users with a new environment that handles video information while securing mutual compatibility in the various systems that handle next-generation digital video information.

The basic DVTS protocol has been standardized
by the IETF, and basic
software is available for free on the
Internet. Domestically, it has already been used for research projects such as the GI-POF Project conducted by Keio University’s Faculty of Science & Technology and the Digital Cinema Project conducted by the Faculty of Environment and Information Studies, as well as the WIDE/SOI Project. Additionally, it is being used in many overseas research projects such as US’s Internet2. A number of corporations have consulted us regarding the development of products using DVTS, and we have come to the conclusion that it is our duty to contribute to the development of application systems in the form of a consortium at the Keio Research Institute at SFC. In order to expand this type of basic system in a healthy manner, this consortium is an open organization with the University at its center. By having various systems implement DVTS, an exchange protocol for video information over the Internet, and by interconnecting these systems, a new method of using video images will be born.
DVTS System Outline
DVTS (Digital Video Transport System) is an application for sending and receiving video streams over the Internet. The WIDE Project has been developing this since 1998, and it was demonstrated for the first time at the Super Computer Conference held in Orlando, Florida in 1998. Currently, DVTS operates on FreeBSD, Windows 2000, Windows XP, and Mac OS X. By connecting to the DV device with an IEEE1394 (Firewire) cable, a low-cost, high-definition video transfer system can be built.
It has recently become possible to directly display a DV stream received over the Internet with Windows XP, so DVTS can be used as a high-definition video broadcast system in PC environments connected to a broadband network.
Compatibility of DVTS with PAL
Improvement of DVTS GUI
- Creation of GUI using X11, etc.
- Creation of GUI with Mac OS X
- Enhancement of HELP function
Documentation and manuals
- Enhancement of instructions and manuals
- Enhancement of FAQ
For DVTS technical achievements, things such as a DVTS version compatible with PAL, DVTS versions for every OS, and a DVTS version with an easy-to-use GUI are some of our priorities. Additionally, tasks such as the maintenance of rights-related issues for the use of DVTS are also the responsibility of our consortium. A major goal of our consortium is to provide a venue to exchange information regarding the various systems using DVTS. Another goal is the research and development of a new format for handling videos by maintaining interconnectivity between systems. As the consortium progresses, we will work on standardization for IETF together with consortium members if the need arises.
