2. The management and classification of software should be reasonable and logical; The four basic functions of "editing", "scheduling", "publishing" and "showing" should be simple and easy to use, and the management and classification of documents should be reasonable, and the operation methods should conform to the "fool-like" way. In management, every step is compact and reasonable, and every link is more logical.
3. The software upgrade is convenient. System upgrade necessarily involves software upgrade. In most cases, players are distributed in different places in different regions, so software upgrade needs to be convenient and simple. There are many ways to upgrade software, such as manual upgrade and network upgrade. Among many upgrade methods, the simplest one is remote network upgrade, which can realize background upgrade without affecting other foreground work.
4. The software is easy to install, debug and reset in case of failure. Software with simple installation, debugging and fault reset can not only bring convenience to builders and software suppliers, but also greatly reduce after-sales service time and bring convenience to users. Therefore, when choosing software, this function has to be taken seriously.
5. Security and stability of software. Security confirmation of software data and software stability during the whole uplink download process.
(2) The selected software must have the following basic functions.
The template editor edits and makes different program templates according to the nature of the broadcast content, and specifies the broadcast attributes of each area in the template.
Schedule according to the pre-plan, apply the application template, and edit the daily/weekly/monthly program list.
The information release will release the prepared program list to each media player according to the priority.
The terminal play that media player accord to the received program list, and plays the media information edited in the program list as plan.
The terminal management system can realize the grouping management of players; Real-time monitoring, which can monitor the player's status online, such as managing storage space, adjusting volume, and monitoring playing pictures in real time.
According to the function, the authority management system divides the authority into: viewing, editing, scheduling, management, publishing, etc. Permission distribution is reasonable, and different users can divide different permissions according to different needs.
Principles and requirements of multimedia information publishing system
The design of multimedia information publishing system embodies the following principles:
Versatility: it can play all kinds of multimedia information in the planning museum and is compatible with most media standards at home and abroad.
Advanced nature: the whole system maintains a certain advanced nature, and the equipment and technology adopted are all internationally advanced at present.
Manageability: the system is easy to manage, with complete functions and reasonable distribution of various management rights.
Practicality: The system components are cost-effective, easy to maintain, easy to use and low in running cost.
Scalability: The system adopts a structured design, which can adapt to the growing expansion demand. When the system is expanded, it is only necessary to simply add hardware equipment.
Flexibility: The system has simple structure and flexible function configuration, which makes full use of existing network resources and does not interfere with the business needs of other departments.
Reliability: Embedded system is adopted, which is safe and reliable.
The system needs to be able to play all kinds of multimedia information in different environments, including pictures, words, audio and video, live content and so on.
The whole system is advanced, and the adopted scheme, equipment and technology are mature and leading at home and abroad.
The playing of multimedia information such as audio and video media and text is not affected by the network bandwidth, and can be played immediately or in strict accordance with the schedule.
It can realize the complete remote centralized management and control of the terminal. At the same time, each control point can release its own video and audio information according to the authority management of some time periods, and multi-level user authority control can provide different operation interface views according to different user roles, which is in line with the characteristics of large-scale management, decentralized functions and centralized management authority in the planning hall.
The hardware terminal supports a variety of interface protocols and is compatible with a variety of display devices, including plasma display (PDP), liquid crystal display (LCD), CRT display, projection display, network touch terminal, multi-screen splicing display wall and so on. The software platform is compatible with various external real-time information interfaces.
Modular design idea can provide customized development services and various optional modules.
Terminal transmission control and content push protocols are open, which can support the conditional access of third-party vendors to this terminal platform.
The system has simple structure and flexible function configuration, and both servers and terminal devices can be grouped and clustered, making full use of existing network resources.
The system can not only play local information, but also support remote play and management, which will prepare for the networking and centralized control of all planning pavilions in the future.
All players adopt embedded system, which is stable and reliable, free from poisoning and crash.
The whole platform is closed, which can carry out security authentication management on the content and fully guarantee the broadcast safety.
