I^2C总线在彩色电视接收机中的应用

On Colour-IV I^2C General Line

电视机采用 I^2C 总线控制技术后,CPU 和被控集成电路引脚大量减少,简化了电路,提高了产品可靠性,而且为增强 CPU 和被控电路功能创造了条件,给生产和维修带来了极大方便。

Since the techniques of I^2C general Line control are emplayed in TV sets,the number of CPUs and controlled integrated circuit feet has been greatly reduced,which not only results in the simplified circuit and enhancement of reliability of TV Sets,but also creates the conditions for the increasement of functions for the increament of functions of CPU and controlled circuit .This will bring great conveniences to the production and maintenance of TV sets .However, because of the differences between I^2C and common TV sets.In their breakdown and mechanison hence the differences in judgement and analytic thinking as well as the methods and procedures of overhaul during their maintenanance.
