Playing system and method based on satellite+4G multimedia information playing terminals

Abstract

The invention discloses a playing system based on satellite+4G multimedia information playing terminals. The playing system comprises a server, a remote management platform, a satellite ground control station, a satellite, a plurality of satellite+4G multimedia information playing terminals and a plurality of display terminals. The remote management platform is used for making a multimedia program playing plan list. The satellite ground control station is used for downloading multimedia files from the server according to the multimedia program playing plan list and uploading checked multimedia files to the satellite. The satellite+4G multimedia information playing terminals are used for downloading and playing the multimedia files in a satellite/4G receiving mode according to the multimedia program playing plan list. The invention also discloses a playing method based on the satellite+4G multimedia information playing terminals. In a connection mode of combining a satellite network and a 4G network, the working stability of the system provided by the invention is enhanced, the system safety is ensured through a plurality of check mechanisms, and moreover, the system maintenance and operation investment are reduced.

Description

technical field [0001] The invention relates to the technical field of multimedia information dissemination, in particular to a playback system and method based on a satellite+4G multimedia information playback terminal. Background technique [0002] With the wide application of multimedia technology in various fields in recent years, the market demand for multimedia information playback terminals such as smart display devices and advertising machines is also increasing. At present, the multimedia information playback terminals on the market all download multimedia files to the multimedia information playback terminal through 4G network, wired Ethernet and WIFI network, and then play them. [0003] To download multimedia files through wired Ethernet, it is necessary to implement the laying of wired Ethernet before installing the multimedia information playback terminal.

Problems solved by technology

[0003] To download multimedia files through wired Ethernet, it is necessary to implement the laying of wired Ethernet before installing the multimedia information playback terminal. Download multimedia files in various ways; downloading multimedia files through WIFI network requires the implementation of WIFI network construction before installing multimedia information playback terminals, and due to the limited coverage of a single WIFI network, weak signal penetration, and signal quality It is easy to deteriorate with the influence of the surrounding same-frequency signal interference and many other reasons, making the way of downloading multimedia files through the WIFI network unable to meet the needs of most users, and has basically been eliminated; downloading multimedia files through the 4G network, Due to the timely update of program content and saving a lot of manpower maintenance costs, it is more and more favored by the advertising industry

However, with the rapid development of high-definition technology, 4G downloads of multimedia files are also facing huge challenges. Currently, users have increasingly high requirements for the clarity of playback files, and the amount of data transmitted for multimedia files has doubled. The high 4G communication costs make post-operation high cost

In addition, with the addition of multimedia information playback terminals, multimedia file storage servers need to carry a large number of concurrent downloads and accesses. The hardware configuration, network architecture, and bandwidth of the server are all facing challenges, and the operating and management costs of the server have also increased sharply.

Due to the uneven management level and personnel quality of the operating companies, illegal content is misbroadcasted from time to time, which has caused extremely bad influence on the society
