<p>A video recorder system (10) adapted to receive subscription television services is of the type which controls access to the subscription services by means of a smart card (26). Where payment is due for each programme received, the viewer is required to make a positive affirmation of purchase by pressing an affirmation button (30) as the programme is received. To enable reception in the absence of the viewer by use of the programmer (32), the programmer is provided with means actuable by the viewer when a programme is being set into the programmer. An indication of whether an affirmation of payment is associated with the programme to be recorded is stored in the programmer, and when the programme to be recorded is received automatically authorises the descrambler control circuit (22) which charges the card (26) and enables the descrambler (16) as though the affirmation button had been pressed.</p> |
