| Abstract: | The interference of video cable transmission is one of the important reasons that directly affect the quality of the video signals, and also the most difficult problem in the video engineering. This paper analyzes two primary elements of the interference in video cable transmission: interference of medium wave and that of 50 HZ electric current. At the same time, four effective methods to control the interference are demonstrated. |
