点歌终端广泛应用于KTV中，是一种由KTV消费者人为控制进行点歌等操作的装置。目前，KTV设备进入更新时期，随着包房内人数和服务内容的增加，需要两台以上点歌终端；政府提倡的健康大众娱乐文化，也增加了量贩式KTV的内容。KTV点歌系统经过几代发展，为KTV消费者带来更多的方便以及更完善的服务。然而当前点歌终端仍然是采用有线方式进行数据通信和控制。由于连线的限制，点歌受到座位、房间布局能因素的限制，使得并不是每个KTV消费者都能方便的进行点歌。同时点歌时也只能通过歌曲类型、歌星、歌名拼音、歌名笔画、歌名字数、排行榜检索歌曲。KTV消费者无法输入歌名，直接按照歌曲名称进行歌曲检索。The song ordering terminal is widely used in KTV, and is a device that is manually controlled by KTV consumers to perform operations such as ordering songs. At present, KTV equipment has entered an update period. With the increase of the number of people in private rooms and service content, more than two song ordering terminals are needed; the healthy mass entertainment culture advocated by the government has also increased the content of mass-market KTV. After several generations of development, the KTV ordering system has brought more convenience and better services to KTV consumers. However, the current song ordering terminal still adopts wired mode to carry out data communication and control. Due to the limitation of the connection, ordering songs is limited by factors such as seats and room layout, so that not every KTV consumer can easily order songs. At the same time, when ordering songs, you can only search for songs by song type, singer, song title pinyin, song title strokes, song title number, and ranking list. KTV consumers can't input the title of the song, and directly search for the song according to the title of the song.
