An embodiment subscriber identification module includes a first communication interface, including first pads intended to be coupled to a modulator-demodulator circuit; a second interface, including second pads intended to be coupled to a subscriber identification module card; and a switching circuit, configured to couple the first pads to the second pads or to a communication module integrated to the subscriber identification module. Another embodiment concerns a method of controlling the module.

Wireless communication device and method

In a method for the display of teletext headers on a television receiver screen during a search for a teletext page, the teletext service uses a first group of characters comprising fixed characters and locations to receive variable characters and a second group of sets of characters, each set of characters being proper to a language and being designed to be introduced selectively at the locations of variable characters of said first group. The set of characters to be introduced into the first set is selected as soon as the first data packet enabling it to be identified is received by the TV receiver in such a way that the headers are displayed properly.

Method for the display of teletext headers

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.
