In a method of teletext management, the data processing is separated into at least two tasks. A first task deals with the processing of the data from the rough extraction, and a second task carries out the rest of the data processing. The first task activates the second task by an interrupt with a priority lower than an interrupt activating the first task. The method thus enables the interruption of the second task to carry out a following first task, thus eliminating any timing drift that may cause the loss of the data packet coming from the rough extraction.
