LED VIDEO Display Cluster Management Program

LED VIDEO Display Cluster Management Program




As LED displays get widely used in various sectors such as advertising, stage, traffic and sports, display operators have their scope of business expanded rapidly from city operation to national, even international operation. The original media release means are far from meeting the needs of business. On the one hand, the resolution of every display is different, so is the content played during different

period of time. On the other, displays at different places may encounter incalculable failures.

In view of the problems above, the Nova team, with the help of its unique creative concept and strong research and development strength, released an optimum and most practical cluster broadcast control management program, which, a multimedia remote

centralized release and control software based on broadband Internet, provides safe, reliable and easy-to-use industry application solutions for LED display cluster control and management.





Architecture




1 Program Introduction

Nova display cluster management program can give remote release of playing scenario, monitor playing and screen status, impose remote control on screen luminance and power switch, and so on. Enjoying flexible network structure and easy installation and arrangement, the program, only by plugging the terminal display into the Internet and logging on the terminal to the Nova’s service platform via browser, can make group management of terminal displays, and achieve remote release of media and playing scenarios, monitoring of screen status, remote control of screen luminance and power switch according to applications with the help of the remote management terminal display of management center software.

Nova display cluster management program has three parts: service platform NovaCloud, management center software MC-go and terminal control software (the terminal software of Nova M3 synchronous system is MarsSite, and the asynchronous system PAD100 has built-in terminal software).

The service platform NovaCloud is the core of data interaction and data management for the whole program, providing services for fulfilling all functions. The service platform NovaCloud is deployed in high-speed backbone networks, so that adequate consideration shall be given to network security, database security and so on. In addition, according to the terminal data size, adequate acceleration servers shall be provided to balance and meet the bandwidth demands of every terminal.

MC-go, user operation software, fulfills such business functions as preparation of playing scenario, remote release and remote monitoring; the software has good user experience, meeting the user demand of managing thousand displays only by one person.

Terminal control software functions as media playing and screen status monitoring of LED display.

Nova Cloud is a set of software used for multimedia remote centralized publication and system centralized monitoring based on broadband internet to provide the industry application solution featured in safety, reliability, centralized management and standardization and easy extension for LED display cluster control and other display cluster systems.

Nova Cloud solution mainly includes three parts which are Nova Cloud server, integrated playback control software( MC-go), terminal software (MarsSite, PlutoSite). It can fully support Nova synchronous and asynchronous control systems.

When it is applied to the synchronous control system, it includes Nova Cloud server, MC-go, and MarsSite. The terminal is a playback control computer, to run the terminal software MarsSite. When it is applied to the asynchronous control system, it includes Nova Cloud server, MC-go, and PlutoSite. Asynchronous control card PSD100 shall be as the terminal to run the terminal software PlutoSite.

Terminal is managed by management center (MC-go), to achieve the functions such as schedule creating, publishing, monitoring, etc. Management center uploads the commands and playback information to the server, the terminal periodically downloads the commands and schedule from server and transfers the feedback information back to the server; the terminal and MC-go account must be registered on the server, and otherwise, the interaction among the three cannot be achieved.







System Features




1) Centralized release

Base on the broadband Internet architecture, support the standard HTTPS (HTTP+SSL) and FTPS(FTP+SSL) server, provide the safe and reliable high speed information release and download service, and remotely, centralizedly and standardizedly manage the media release.

2) Remote monitoring

Base on the leading Nova monitoring system, support remotely and centralizedly collecting the running parameters of display screen, intuitively and comprehensively control system operation state in real time, support alarm function for the fatal problems occur to the system, and provide efficient system maintenance business environment.

3) Layered protection

The system uses multiple security measures, covering all aspects of data storage, transmission and play and so on, so as to ensure data consistency and reliability.

The system uses the registration mode to manage the terminal access and MC-go authority, ensuring that the system access security is controlled.

4) Media management

All terminals of one user share one media library, and the system doesn’t upload repeatedly while terminals playing the same media or play schedule including the same media, which improves the media release efficiency and saves server space.

5) Easy to extend

Nova Cloud server system adopts extensive system architecture to support deployment from single server to multiple acceleration servers so as to meet the demands of different scale of cluster application from several terminals to thousands of them.

The system is easy to expand, which provides users with optimal solutions both for cost and performance, and the system will gradually increase deployment as business grows, so as to protect customers' investments.

6) Autonomous terminal

The terminal software is autonomous, and unattended.

The terminal automatically interacts with the system, automatically download schedule , automatically detects the system status and reports to the system, automatically obtains a system control command and then executes such command, feedbacks execution results to the system, without human intervention.
