Abstract: 2.1 On known video magnetic tape recorders, the searching for certain positions on the tape is performed by means of a control button, which can be turned and adjusted axially between two positions and can be locked in each of the two axial positions. This known device requires a separate operating mode selection mechanism, demands considerable production effort and allows the direction of tape transport to be changed only by turning the control button back through its neutral position. The novel one-button control is intended to avoid these disadvantages. 2.2 Pressing the rotary button (1), irrespective of its angular position, causes closing of a switch (9), the output signal of which is fed to a microcomputer (8). Each time the rotary button (1) is pressed, the said microcomputer switches off the tape transporting motor (12). Each time after the rotary button (1) has been pressed, a return spring (11) returns it axially into its initial position. 2.3 Searching for certain positions on a tape on video magnetic tape recorders. <IMAGE>

Abstract: A system in a subscriber television network for enabling descrambling of a received scrambled signal on a prepaid basis and/or an impulse-purchase basis. A received mask signal uniquely related to the scrambled signal is compared with a received authorization signal indicating whether the subscriber is authorized to receive the scrambled signal on a prepaid basis and a prepaid signal for enabling descrambling is provided when the compared signals match. A not-prepaid signal is provided when they do not match. A received cost signal indicating the charge for descrambling the scrambled signal and a received credit signal indicating the subscriber's accumulated credit are processed with reference to a stored record of the subscriber's prior accumulated charges to determine whether the subscriber has sufficient available credit to pay for descrambling of the scrambled signal. If a program is not prepaid and if sufficient credit is available, the subscriber is given the option of causing the signal to be descrambled on an impulse-purchase basis. To prevent a subscriber from obtaining descrambling through such deceit as changing the mask, authorization, cost and/or credit signals, these signals are processed with key signals which are used in scrambling and descrambling the television signal such that descrambling is prevented if any of the mask et al signals is changed.
