Multimedia Information Publishing System Solution

1. System Overview

  In the information society, multimedia information is ubiquitous. Multimedia information includes text, sound, graphics, images, animations, videos, and so on. Nowadays, multimedia technology is often combined with the Internet, relying on the digitization and interactive processing capabilities of computers, which greatly promotes the development of multimedia technology. The multimedia information publishing system developed by our company is such a product. The system can combine audio and video, TV screens, pictures, animations, texts, web pages, information data, etc. into a wonderful program, and make it through the network The program is pushed to media display terminals (supporting monitors, advertising machines, TVs, LEDs, splicing walls, touch screens, projectors, etc.) distributed in real time, so as to display wonderful pictures and real-time information in various designated places. The perfect position is displayed in front of the people who need it. Realize the unified production, release, review, and terminal management of program content. The multimedia information publishing system is suitable for public places such as banks, governments, hospitals, schools, enterprises, buildings, hotels, and supermarkets.

2. System composition:

  The multimedia information publishing system is composed of four parts: the background server (cloud platform), the network platform, the management platform client, and the media publishing terminal.

The system topology diagram is as follows: 

The functions and roles of each component are described as follows:



  2.1. Background server (cloud platform)

  The server group is set up in the network management center of the headquarters and adopts the B/S management structure to manage, control, monitor and distribute various multimedia information on various information playback media. It consists of the following parts:

  1. WEB server: Responsible for accepting terminal and client requests and automatically forwarding the requests to idle application servers.

  2. Interface server: Responsible for processing requests received by the front end, performing business processing, and returning processing results.

  3. Database server: responsible for providing business data storage services.

  4. FTP file server: Responsible for providing file upload and download services.

  Note: WEB server and interface server can use the same server

  2.2. Network platform

  The system supports multiple network connection methods: (LAN/WLAN/ADSL/3G, etc.)

  The terminal is connected to the server through the network to obtain the playlist and play content.

  2.3. Management platform client

  Through this management platform, the client can log in to the server, complete the allocation of new users and the division of corresponding permissions, realize the remote, distributed real-time management of the terminal, and realize the release of multimedia information, control information, and program playlists.

  2.4. Media release terminal

  Professional display equipment, information release play box

  The play box terminal is connected to the server group through the network, and automatically downloads the information content and playlists that need to be played, so as to realize the colorful multimedia information play. At the same time, the software can be automatically upgraded according to the strategy. The terminal has Android and X86 solutions.

  2.5. Design principles

  The system strives to be designed to be safe, reliable, flexible and easy to use, while embodying the following principles:

  ☆Advanced: The entire system maintains a certain degree of advancement and is forward-looking. It can simultaneously control various media terminals of Android and X86 solutions through the same background system. The equipment and technology used are currently internationally leading.

  ☆Security: The system performs high-strength encryption processing on all transmitted messages and terminals, and uses private encryption technology to ensure the safe operation of the entire system and prevent malicious tampering and destruction of content.

  ☆Reliability: The system has undergone strict aging and stability experiments to ensure safe, stable and reliable operation.

  ☆Legality: The system must ensure the legality of public-facing information.

  ☆Controllability: Download settings according to network operation conditions (such as: network idle state) to ensure that the main business network is not affected.

  ☆Controllability: Download settings according to network operation conditions (such as: network idle state) to ensure that the main business network is not affected.

  ☆Management: unified management, complete functions, reasonable allocation of various management permissions, and can meet the hierarchical management applications of various application scenarios.

  ☆Practicability: The components of the system have high performance-to-price ratio, easy to maintain, easy to use, and low operating cost.

  ☆Ease of use: After a large amount of user experience, in line with the user's thinking habits, the system uses a 7-key remote control to control all functions. Through a large number of prompts and humanized menu design, users do not need to be trained as convenient as operating a TV.

  ☆Scalability: The structured design can adapt to the ever-increasing expansion requirements. When the system expands, you only need to simply add hardware devices. The software platform is very flexible, and flexible applications can be added according to different needs.

  2.6. System Features

   safe and stable

  ☆The terminal adopts both Android and X86 solutions, the system is stable, does not crash, and has strong anti-virus capabilities

  ☆The onboard watchdog design can realize automatic recovery when the device is abnormal.

  ☆Network download, local storage and playback, low network dependency.

  ☆Secondary review of broadcast content and technical monitoring to prevent the system from being controlled by illegal users and ensure the legitimacy of information to the public

  ☆The terminal and the server are bound and mutually verified through the private key to ensure the security of information exchange

  ☆All distributed resources and playlists are highly encrypted to ensure the security of the broadcast information

  Bandwidth controllability

  ☆Secondary flow control: Only through secondary distribution and flow control can the network bandwidth be unblocked and the normal operation of other services such as office networks can be guaranteed;

  ☆Timed download: The download time of the program source can be set at will (for example, the download time of the program source is set from 0:00 in the evening to 6:00 in the morning), so as to make full use of idle network resources and ensure the normal use of main business;

  ☆The monitoring function adopts independent patented passive terminal monitoring technology, which greatly saves network traffic and network management (control, transmission, monitoring) under the premise of ensuring accurate monitoring

  ☆ System network remote control, realize unified management and improve management efficiency;

  ☆Play content network transmission, realize unified production and release, and the content is more professional and accurate;

  ☆Remote monitoring: The management platform remotely monitors the terminal to improve maintenance response speed, reduce maintenance costs, and improve system efficiency.

  ☆The terminal actively reports back when an abnormal fault occurs, and can give an alarm to the operator

  Split screen grouping

  ☆Split screen function, support multi-screen display at the same time. According to the requirements of different content to be played, various layout forms are produced to make the content to be played more vivid, novel and flexible;

  ☆Group management, which can play different content for different business locations and different usage areas, and improve the pertinence of information content;


  The system has strong scalability, leaving a variety of hardware communication interfaces to meet customer customization needs. It can be connected with banks' queuing system, pricing system, exchange rate, stock market quotation and other systems, and supports multiple information formats. Avoid repeated investment in equipment and reduce system investment costs. At the same time, the system has flexible expansion capabilities, and various applications can be added according to customer needs.
