1. Demand Analysis |
|
|
| |
The complex structures of government, and the importance of government business ,leads to the requirement for a high quality network video conferencing system. |
|
|
| |
 |
| |
|
| |
1.1 Remote Interaction, High Definition Video |
|
|
| |
To meet the government's requirements, network video conferencing systems should support large scale conferences beyond regional boundaries, and feature high definition video and audio and stable and smooth transfer. Departments of the government operate in different provinces, cities, counties, and villages.
They seek to
·macro-control the development of the economy and society through partnership with different organizations
·collect the information about the economy, business and society
·to hold international seminars for facilitating the development of the Chinese market economy and associated reforms.
After the deployment of network video conferencing systems, the government is able to build up simulated and practical virtual meeting rooms, reduce travelling time of civil servants and the costs of meetings, and alleviate problems caused by the lack of meeting places.

| |
|
| |
1.2 Dual Display, Multifunctional Information Collection |
|
|
| |
To meet the governments' requirements, the network video conferencing system should support double stream technologies, providing video images and PC images in which the content can be controlled by both single display and double display. At the same time, it should enable the users to control the cameras remotely, to record the activities in meeting rooms simultaneously and realise VOD and video live broadcasting/multicasting.
The training of civil servants is recognised as of vital importance in the effective delivery of the strategy and the associated aims and objectives of the government.
The government seeks to consult with its citizens on the provision of services and actively encourages them to put forward proposals and suggestions as to how their needs can be met.
Network video conferencing systems with comprehensive remote controlling functions, can heighten a participants' sense of involvement in a way that traditional meetings can not. They can provide a focus on , and a demonstration of, the key points and record the communication processes for future reference.

|
| |
1.3 Intelligent Data Transfer |
|
|
| |
The basic functions offered by the network video conferencing system facilitate government business.
These include
·the transfer of Word and Excel files
·sharing of video and audio presentations
·labeling on white boards
This can help the government hold procurement meetings and demonstrate the documentation and the results of procurement tasks. It is easier for the government to collate various files prepared during the bidding process while meeting the stipulations of the bid. The network video conferencing system can transfer the data quickly, reducing costs and saving time.

| |
|
| |
1.4 Safe and Stable Network |
|
|
| |
The security of the governments' information impacts on the whole nation. Details of meetings, strategies and operational measures, and other confidential information should be protected from stealth. The network video conferencing system has to feature safe and stable transfer systems. |

·Acoustic Echo Cancellation (AEC), Automatic Gain Control (AGC), Noise Suppression (NS), Voice Activity Detect (VAD), and JitterBuffer, which can keep the video effects in the conferences smooth and clear under an unstable networking environment. |
| |
|
| |
2.2 Dual-Stream Technique and Meeting Recording |
|
|
| |

|
| |
2.3 Multi-Format Transfer of Electronic Data |
|
|
| |
With the perfection of OA system in governmental departments, e-office has become common practice. However, governmental departments' documents are characterized by their weight of number, complex categories and the different transfer formats within the network. The AVCON network video conferencing system provides strong function development capability, real-time video communication, e-documents demonstration, network resource access, static image and text transfer, e-whiteboard transfer, multi-media demonstration, meeting minutes, and LAN sharing meetings. This easily provides the intelligent transfer of data for government co-operation between government departments. |
| |
|
| |
2.4 Encrypted Transfer Technique |
|
|
| |
The uniform and perfect authority controlling system of the AVCON video conferencing system ensures the unique identification of each user. The entire network adopts an encryption algorithm which is used for WEB page data transfer and the communication and stream transfer utilises MD5 and DES encryption techniques. These two features can effectively prevent attack and information access from external networks and avoid information leakage in the transfer process.
The port of AVCON network video server only forwards data and accesses the database rather than handling the files. All the port connections are equipped with handshake protocol customized by AVCON, which can basically prevent system safety risks from the port of AVCON network video server. |
