Abstract：With the popularity of large screens in the consumer market and the abundance of online and offline video resources， enjoying dynamic remote scenery at home has become an interesting application. This paper proposes a 5G+AI system for users to interactively appreciate different scenery in remote areas. The system understands the current environment， and the weather conditions in the remote scenery video are related to the local environment in different ways to bring users a natural and pleasant viewing experience. At the same time， the system can change the layout of the scenery video according to the users location and perspective， so that when the user is walking and looking around in front of the screen， it feels like watching the outside scenery through a real window. A prototype consisting of a large screen and several low-cost sensors was realized， and a series of tests were carried out. The results show that the proposed system can effectively improve users experience of viewing natural scenery and make the process more enjoyable. The system is suitable for screens of various sizes and is easy to install， making it an expandable and easy-to-use consumer device in the smart home.

大屏幕的制造技术在最近的二十年中发展迅速。随着成本的不断降低，它已成为智能家居中的重要组成部分[1-2]。它有效地增强了日常生活中的各种娱乐和商务功能，例如电视和电影观看，游戏，电话会议等[3-4]。随着风景视频资源的丰富，还可以通过大屏幕欣赏美丽的风景，并可以通过房间中的真实窗户观看[5-6]。例如，从北京的房间欣赏伦敦泰晤士河的动感风光，或者从巴黎观看悉尼的屈臣氏湾，而不必出国旅行，将是很有趣的。……
