Abstract
The invention principally relates to a device and to a method for writing in a storage device of the stack type. The invention relates to the use of stacks (1) of the first-in, first-out (FIFO) type for the unscrambling of television images. In order to be able to write in such a stack (1) starting from a desired address, the procedure begins with writing non-pertinent information in order to increment the stack's internal counter to which there is no access. Then, starting from the desired value of the counter, pertinent information is written. It is possible to rewrite pertinent information over the non-pertinent information placed for example at the start of the stack. The present invention applies in particular to the use of special memories for uses which have not been foreseen by the manufacturer. It applies more particularly to the use of stacks (1) of the first-in, first-out type for the unscrambling of television images.
