Smart TV brings people wonderful audio-visual experience and becomes an important part of home life. Recently, the Internet Television Working Committee of the China Network Audiovisual Program Service Association issued the Proposal on Standardizing the Charging Behavior of Smart TV, proposing to smooth the problem solving channel and optimize the user experience. Mr. Zhang, who turned his mobile phone into a remote control in Zhengzhou, Henan Province, recently decided to replace the TV that had been "in service" for more than ten years at home. He was dazzled by the variety of smart TVs in the mall. "In the past, TV can only watch cable channels. Today's TV has become 'smart' and has various intimate functions," Mr. Zhang said. How does TV become "smart"? Industry insiders believe that most TV sets in the past only support cable TV, and you need to connect to a set-top box or cable TV network to watch program videos. As long as smart TV is connected to the network, it can watch rich video resources, not limited to live broadcast of TV stations, but also network video, network TV, etc., all of which depend on the operating system carried by smart TV. On the basis of smart TV, some manufacturers extended the concept of "smart screen". "As the main entrance in the family scene, the smart screen is the core support of Huawei's intelligent strategy for the whole scene." Yu Chengdong, the executive director of Huawei, said that the smart screen is actually equivalent to a super-sized mobile phone, which can be directly projected from the mobile phone to the smart screen when watching video and playing games, and the experience is more high-definition and smooth. At the same time, it can also directly control the TV on the mobile phone, making the mobile phone become a remote control. TV is one of the important household appliances in the life of the elderly. Sometimes the interface of smart TV dazzles the elderly. In order to make smart TV more friendly to the elderly, the "Technical Requirements for Aging Design of Smart TV" came into being. It not only continues the requirements of smart terminal related products in terms of vision and hearing, but also has special considerations in terms of remote control. It is reported that Skyworth, Hisense, Xiaomi and other color TV companies have started to follow up the transformation of aging products. For example, Hisense Smart TV has developed humanized functions such as voice recognition, profile mode, remote control, etc. in combination with the operation characteristics and viewing habits of the elderly, reducing the number of keys on the TV remote control from 28 to about 10, and the elderly can master the use method in less than one minute. In addition, the elderly can also control smart TV through 24 dialects, such as Cantonese, Sichuan dialect and Shanghai dialect. Ms. Luan, who transited from mobile terminal to large screen terminal in Yantai, Shandong Province, bought a smart TV for her family this Spring Festival. Unlike the old TV that has been eliminated, this new TV can not only watch cable TV, but also install iQIYI and Tencent Video. It can "catch up" with the current popular TV dramas at any time, regardless of time constraints. "Our family gathered to watch TV and enjoyed ourselves," Ms. Luan said. Zhu Di, a researcher at the Institute of Sociology of the Chinese Academy of Social Sciences, believes that the television in the living room of many families has become furnishings, and the study and bedroom have become entertainment places of different generations, "In the past, even if a family is sitting in the living room, they are also looking down at their mobile phones and paying attention to their screens. Smart TV has gradually attracted everyone from the 'small screen' to the 'big screen', becoming the entry point for consumption upgrading. Family affection is valuable, and more opportunities should be created to accompany them
