Yes, those ripples are analogue line echoes caused by impedance mismatches. The termination at the receiving end has to be a perfect match for the impedance of the cable, so it is not the TV's fault with no control over the cable in use. If analogue was good enough for high pixel rate video, HDMI wouldn't have been developed - digital interfaces eliminate all distortions in the transmission medium, until the distortions prevent any fidelity at all.
