Data broadcasting system and a receiver for one such system
First Claim
1. A system for broadcasting periodically updated data to intelligent terminals (T1, T2, T3) comprising memory means, data processing means, means of connection with peripherals, and a display screen (E1, E2, E3) which can be placed on standby automatically in the course of periods of reduced activity of the associated terminal which remains powered up, characterized in that it comprises, for each terminal, an FM receiver (K) designed to capture data transmitted on an FM radio transmitter subcarrier (SP3), this receiver (K) comprising a connector (C) for linking to a peripheral socket of the terminal, and in that software is installed in the terminal (T1, T2, T3) for utilizing the data captured by the receiver (K), the assembly being designed to ensure the displaying of the captured data on the screen when it is on standby, these data moreover being stored in memory means of the terminal and being retrievable for display.

Abstract
A system for broadcasting data, which are periodically updated, to intelligent terminals (T1, T2, T3) comprises a display screen (E1, E2, E3) which can be put on standby automatically during periods of reduced activity of the terminal, which remains powered up. The system comprises, for each terminal, an FM receiver (K) which is provided to capture the data transmitted on an FM radio transmitter subcarrier, the receiver (K) comprising a connector that is used to link to a peripheral connector of the terminal. A software program is installed in the terminal (T1, T2, T3) in order to process the data captured by the receiver (K). The assembly is used to ensure that the data captured are displayed on the screen when the terminal is on standby. Moreover, the data are stored in memory elements in the terminal and can be retrieved for display.
