Qt-based multimedia networking information publishing terminal system

Abstract

The invention provides a QT-based multimedia networked information publication terminal system, which comprises an FTP (File Transfer Protocol) downloading management subsystem, a communication subsystem, a material management subsystem and a playing management subsystem; the FTP downloading management subsystem takes charge in downloading multimedia materials into the local disks of terminals from a platform server; the communication subsystem networks the terminals and the platform server, and carries out communication command interaction with the platform server; the material management subsystem takes charge in the read-write management of all the configuration files of the system and the allocation management, deletion management and query management of multimedia materials; and the playing management subsystem takes charge in playing multimedia materials according to playing rules and playing styles. The QT-based multimedia networked information publication terminal system is portable, has the ability of intelligently managing the spaces of local disks and local material files and FTP power-off reboot self-test downloading ability, and can shorten the coding time and reduce the coupling of modules and the flow cost.

Description

【Technical field】 [0001] The invention relates to a terminal system for issuing multimedia networking information, in particular to a terminal system for issuing multimedia networking information based on QT. 【Background technique】 [0002] Commercial advertisements target audiences in the target market, especially get involved in the depths of people's minds, and can gain the general attention of product users, purchase decision makers and potential consumers. In the past, building TV advertisements, bank interest rate exchange rates and information releases, shopping mall advertising carriers and information releases, hotel multimedia information releases, community cultural construction, hospital queuing and information releases, government multimedia information releases, corporate network TV stations, telecommunications or mobile The information release methods in various communication terminal fields such as multimedia information release in business halls mainly rely ...

AI Technical Summary

Problems solved by technology

[0004] 1. Non-portable: Since the development of C language is more dependent on the system, if the source code written is to be ported, the source code needs to be rewritten, which reduces the portability of the application or system;

[0005] 2. Limited support for interface effects: Since the C language itself is process-oriented programming, there is insufficient support for user interface beautification, and limited support for multimedia videos, visual effects, and animations;

[0006] 3. Long coding time: The classes provided by the C language are all provided by the system. For the development of the system or application, it is necessary to independently develop various exclusive modular class libraries, and spend too much time on coding, which prolongs the development of the software. or when the system was brought to market;

[0007] 4. Poor module coupling: Since the C language itself is process-oriented programming, there is insufficient support for reducing module coupling, which will have a certain impact on the design of the overall modular architecture of the system

[0009] 1. Because the original intention of the terminal system development is the exclusive terminal system software, which does not have the ability to adapt to the terminal, so the corresponding terminal system software is developed for different terminals, which invisibly increases the development cost and also improves the version management costs;

[0010] 2. It does not have the ability to intelligently manage local disk space and local materials, which are managed by the corresponding management platform, which leads to insufficient local disk space due to incorrect operation of the management platform, making it impossible to download multimedia information sent to the terminal, seriously affecting the timely release of multimedia information

At the same time, the corresponding management platform clears the terminal disk space, which makes the terminal system waste traffic virtually and increases traffic costs;

[0011] 3. It does not have the ability to self-test and download Ftp power-on, which may cause problems such as not continuing to download after power-on during the Ftp download process, causing incomplete multimedia information downloads

The shortcomings of this technical solution: 1. Although the production cost of the terminal is reduced, the cost of traffic usage is greatly increased. At the same time, if the terminal network processing is unstable, it will seriously affect the playback of multimedia information on the terminal, greatly reducing 2. It does not have the stand-alone playback function. If the network is disconnected, the terminal is useless; 3. The management of local materials is poor. If the terminal is powered off during playback, it may not be able to delete the downloaded files in time. 4. The terminal does not have the ability to self-check and download. If the terminal is powered off during the download process, the download may be repeated after the power is turned on, resulting in wasted traffic.

The disadvantages are: 1. The multimedia playback terminal is only responsible for downloading materials from the management center or directly playing streaming media, and has poor management capabilities for local materials. The material is not cleared in time, resulting in redundant terminal space, which will greatly affect the terminal’s demand for disk space; 2. The terminal does not have the ability to self-test and download. If the terminal is powered off during the download process, the same material may be deleted after power on. Repeated downloads, resulting in a waste of traffic
