At present, it is necessary to set LED electronic screen in hotel banquet hall. The background of wedding scene, product launch, dance and celebration must be backed by LED electronic screen. This kind of on-site activity is characterized by the need to transmit pictures, VCR, subtitles and other information at the same time. Therefore, when using the LED electronic screen, the access devices include computer signals, cameras, network devices, etc. when selecting the LED electronic screen control method, the synchronization control method is needed, that is, the implementation of some peripheral devices such as card, video processor, set-top box, etc. On the other hand, when the guests usually eat, the LED electronic screen can also enrich people’s lives through news broadcast, Olympic Games, summit and other popular programs.
When the functions of LED electronic screen in multi-function conference room are similar to those of LED screen in banquet hall, some information (such as PPT and PDF document on computer desktop) and pictures of some products need to be played at the same time for explanation. Video conference activities (not only product demonstration) may be carried out in multi-function conference room, so as to further improve the clarity of LED electronic screen The LED electronic screen in the conference room needs a small space LED display, and its definition can be further adjusted when playing text and video.
The external wall and the front desk LED electronic screen of the hotel are used as publicity windows to convey the hotel business scope, service items, special menu, time limit activities, recruitment announcements and other information to the outside. This type of LED electronic screen can be displayed asynchronously (i.e. offline), and can cycle to the controller that sends the content to be played to the computer without synchronizing the computer. Asynchronous control system is much simpler than synchronous led control system. For advertising companies that have installed many LED electronic screens in many cities, asynchronous control system is more convenient. 4G wireless receiving module based on the original control card can be added, so as to achieve global unified management in the same place and save time and energy.
