Software: Digital Office Communication Platform

[Virtual Meeting Space]   [H.323 Toolkits] [SIP Toolkit]

The project of Digital Office aims at creating a Communication Platform for multimedia. In this project, we collected and developed some software package, such as the open source code of PWLib, open protocol toolkit of H.323, 3D virtual meeting space, SIP toolkit, and SIP-based multipoint communication system.

3D Virtual Meeting Space:

It is a key technique of CSCW-based Digital Office Collaboration Office Platform, on which people can collaborate with all the others directly as face to face communication. The main features of the virtual scene are that it allows any of the participants walk through the meeting room and able to see videos of all the others. This technique provides the remote applications, such as communication for long distance education and expert diagnosis together.
The core method of virtual scene is based on the Direct 3D toolkit of DirectX SDK of Microsoft

H.323 Toolkit:

The project of OpenH323 aims to create a full featured, interoperable, Open Source implementation of the ITU-T H.323 tele- conferencing protocol that can be used by personal developers and commercial users without charge.
OpenH323 development is coordinated by Quicknet Technologies Inc. but is open to any interested party. Commercial and private use of the OpenH323 code, including use in commercial products and resale,  is encouraged through use of the MPL.
 (Mozilla Public License, MPL).

SIP Toolkit:

Session Initiation Protocol (SIP), is a signaling protocol for Internet conferencing, telephony, presence, events notification and instant messaging. SIP was developed within the IETF MMUSIC (Multiparty Multimedia Session Control) working group, with work proceeding since September 1999 in the IETF SIP working group.
The feature of the toolkit is flexible and easy to extend. Using it, one can easily create a multipoint communication system.
