摘要
通过对WiFi无线数据通信系统的分析,探究其在广播电视频道遥控中的运用,针对电视副机不能独立选台的不足,提出了一种基于WiFi的电视副机遥控器方案。方案中手机选台控制软件发送选台控制命令,利用无线的方式传输至控制系统中的WiFi模块,控制系统对数据进行处理后通过遥控器按键拉出引线排传输至遥控器内部实现对主机频道的控制,从而使副机频道随主机的改变而改变。解决了数字电视副机不能独立选台的问题,使用户可以随时随地跨房间自由切换电视节目。
By analyzing wireless data communication system, its utilization in remote broadcast televi-sion channel control is researched. To solve the problem that the secondary TV machine is not able to choose channels independently, a new scheme based on WiFi is proposed. In this scheme, the control software which is implemented in a eellphone sends out the channel choosing commands, the commands are transferred to the WiFi module of control system via wireless media. After the control system processes the commands data, it transfers the data inside the remoter by the lead row which pulls out from the remote control button, realizing the control function for the main TV machine channels, thus makes the secondary TV machine change its channel with the main TV machine. This scheme solves the problem that the secondary digital television is not able to choose channels independently, and it achieves the purpose that users can change TV programs in different room anytime.
