Ferrite beads employ the mechanism of high dissipation of high frequency currents in a ferrite to build high frequency noise suppression devices

Let me ask you, I'm getting high-pitch interference on my HD TV, which is connected to my cable box thru an HDMI cable. I thought using a hi-def connecter like a HDMI cable is supposed to reduce interference? I just checked and none of the HDMI cables I am using employs these "ferrite beads". Is this something I can retro-fit to each cable?
