从控制角度上看,彩色电视机的发展经历了手控阶段、普通遥控阶段,现在又步入了I2C总线控制阶段。手控彩电虽然具有电路简单、使用简单的特点,但使用极不方便;普通遥控彩电虽然操作方便,但电路结构复杂,控制线极多,严重制约整机功能的开发,且机 From the control point of view, the development of color TV experienced a manual stage, ordinary remote control stage, and now entered the I2C bus control stage. Although the manual color TV with simple circuit, easy to use features, but the use of very inconvenient; ordinary remote control color TV although easy to operate, but the circuit structure is complicated, the control line is very much, seriously restricting the development of machine functions, and machine
