The leader of Ministry of Public Security, evaluated the video conference system of Shanxi Politics and Law website during an inspection: “Shanxi Politics and Law website can be called ‘No.1 website of China politics and law’, and construction of politics and law website in such a way would be a creation in the information construction of politics and law systems.” Shanxi Politics and Law Website is honored as “No. 1 Website” because of the creation in its video conference system, which is sponsored and organized by Public Security Department of Shanxi province. The video conference system is of great significance to the Procuratorate, the Court, the Commission of Politics and Law, the Judicial Department, the Security Department, and the Prison Administration, and has got many No.1 awards in aspects of scale, economic benefit, social benefit, and technical complexity in politics and law system or even in the whole country.

Technical Innovation

      By successfully carrying out this extremely large project with many awards of China No.1, the core facilities of Amplesky such as MCU for video equipment, video wall servers and video recording & VOD servers are of great use. It has been the first time so far in the history of China video conference that 560 terminals are managed by 12 sets of MCU instead of 72 sets, 72 2M-terminals are supported by one single MCU, and simultaneously multi-network-ports are used, 6 groups of conferences are held, and 16- split screen is displayed without additional facilities.
      The successful implementation of this project marks that China users could obtain video conference service of higher quality with less costs, and makes Amplesky the most popular company.

Network Construction

a) Large Volume of Connection

Amplesky MCU Amplesky? VM3500 supports the maximum number of connection in the industry, where 12 MCU could connect 560 conference rooms of 6 organs of politics and law system, and the MCU in the provincial center with extremely large connection capability could simultaneously connect 72 terminals at the speed of 2Mbps.

b) Meeting many kinds of conference requirements of every organ of politics and law system

Amplesky MCU supports simultaneous holding of different conferences, which makes it possible for every organ of politics and law system to have meetings any time according to respective needs. Every set of MCU could support simultaneous holding of many groups of conferences with multi-user management mode without any bad effects exerted upon each other.

c) Functions

1 ．Multi-control concatenation mode：
      Multi-control concatenation mode: during the conference, the administrator in the provincial center could manage all MCUs by operating the main MCU with other MCUs being opened without special operation.

2 ．16 split screens and dynamic switching：
      Dynamic multi-screen: the system supports 2,3,4,5+1,3+4,7+1,8+2,9,12+1,16 split screens where every screen could be chosen freely, the position of some conference room in the multi-screen could be adjusted, some scene could be focused on circularly or switched by audio activation, or set to automatic circular display.

3 ．Chinese captions：
      Chinese captions: the caption of conference room’s name could reveal Chinese names of all conference rooms; static and dynamic captions could display notes on conference subject and temporary notices, etc.

4 ．Dual video stream transmission：
      Dynamic dual video streams transmitted to conference rooms: dual streams mean dual lines of video in one conference room could be transmitted to MCU simultaneously, which in turn will be transmitted to other conference rooms simultaneously by MCU.

5 ．Remote camera control：
      Remote camera control: remote control of far-end camera of broadcasting and image terminals by local terminal saves time for conference organization and communication, so as to have a more natural and convenient proceeding of the conference.
