For example, in places such as shopping malls, conference centers, and public transportation hubs, large screens have become an important medium for information display. These large screens can not only play advertisements and news, but also be used to display real-time data, dynamic information, and interactive content. However, as the number and scale of large screens increase, how to efficiently control and manage the content played on these large screens has become an urgent problem to be solved.

[0003] Traditional large-screen broadcast systems usually rely on manual operation and preset broadcast plans. This approach has the following major problems: First, it lacks real-time and flexibility. Traditional systems usually use timed releases or manual control, which makes it difficult to make real-time adjustments based on actual conditions. Second, unified management is difficult. With the increase in the number of large-screen terminals, traditional systems have high management complexity when facing multiple screens and multiple contents, and are prone to problems such as content scheduling errors and playback conflicts.
