You can seek and step to a location on the disc using any of the videodisc time formats. Seeking is a fast-forward or fast-reverse to an absolute position. Stepping is done, backward and forward, in time units relative to the current position. The default for a step is one time unit forward.

Some videodisc players do not display a picture when you do a step. You get a "squelch" color, which is the color of the screen when a frame is not yet displayed. Some devices, particularly for CLV, cannot be frame accurate.
