Abstract: A method and an arrangement for determining the position of a tape-like medium are proposed. The method provides for counting pulses which are supplied to the arrangement for determining the position to be counted, blocked or cancelled depending on the respective transport state. To this end, it is established whether the transport direction has been constant for a defined amount of time or over a defined distance. The transport direction determines whether the counter is incremented or decremented. In addition, counting pulses which rapidly follow one another are blocked in order to avoid undesirable double triggering. In order to avoid losing blocked counting pulses in an undesirable manner, the latter are stored and are applied to the counter, or discarded, depending on the transport state before and after blocking.

Abstract: A method of correcting picture steadiness errors (or film weave correction) in telecine scanning is proposed, in which, in a first step, at least one sample area of the picture contents of the video signal obtained by film scanning is determined by way of structure recognition, this sample area corresponding to a curvature in the picture contents. In a second step, it is checked, by way of comparison, whether the determined sample areas are recognizable in a search area of the sequential frame. In a third step, motion vector signals are generated when the sample areas are recognized again in the sequential frame, these motion vector signals defining the direction of motion and the extent of deviation of the position of the determined sample area from the position of the recognized sample area. In a fourth step, parameters of a transform function are determined by the motion vector signals.
