Notre thèse souhaite analyser le rôle et la place du média radiophonique dans la société en étudiant la relation établie entre une station et son auditoire dans le cadre des émissions interactives, omniprésentes sur la bande FM. Le cas des émissions service, qui affichent une intention d’aide et de conseil à l’auditeur dans sa vie quotidienne, révèlent et reflètent pour nous les nouvelles orientations dans la pratique et les usages des médias. Mais, en ce cas, les stations de radios sont-elles actrices ou outils de médiation ? Les publics sont-ils instrumentalisés ou se saisissent-ils de ces espaces médiatiques de manières autonomes ? En prenant en compte l’évolution en cours du média radiophonique, le développement, l’intrusion ou l’imbrication des nouvelles technologies avec des formes médiatiques plus traditionnelles, nous souhaitons mettre en lumière les relations de corrélation ou de causalité, voire de concomitance qui relient les évolutions en cours des uns et des autres, et leurs accommodations par les publics. Pour ce faire, notre terrain de recherche se focalise plus particulièrement sur l’émission de Menie Grégoire sur RTL (de 1967 à 1981), sur « Ça peut vous arriver » sur RTL et sur « Lahaie, l’amour et vous » sur RMC, encore diffusées de nos jours. / The purpose of our doctoral thesis is to analyze radio’s roles in society, observing connections between radio stations and their audience within the context of phone-in programs which are omnipresent on air. Service broadcasts, meanwhile intending to offer help and advice in listener’s day-to-day problems, reveal new ways of using this media. Considering this, are radio stations passive or active devices? Is the audience used by these broadcasters or do they seize it autonomously? By studying the actual evolution of radio, throughout its new forms of technologies as in its most traditional uses, we seek to highlight the causual, comparison and concomitance links among broadcasts, as well as listerner’s reactions to it. In order to do that, our work has focused on Menie Grégoire’s broadcast on RTL from 1967 to 1981, on “Ça peut vous arriver” on RTL, and on “Lahaie, l’amour et vous” on RMC, still emitted nowadays.

This report is a technical verification and validation of Traffic Information Service Broadcast (TIS-B) using the data link VDL Mode 4. The main objective of the report is to examine the usefulness of TIS-B considering the results from tests performed in the Stockholm Terminal Area and for the Advanced Surface Movement Guidance and Control System (A-SMGCS) at Arlanda airport. The results are compared with the requirements that have been set by the standardisation organisations ICAO, RTCA, Eurocontrol and Eurocae. TIS-B is however such a new concept, so most of the operational requirements have not yet been defined. The process for performing the evaluation of TIS-B involves three stages: · Study the requirements on TIS-B, ADS-B, radar and A-SMGCS. · Verify TIS-B by performing tests at Arlanda airport. · Validate the test results through analysis. A theoretical study of slot allocation optimisation is performed to decide how the slot allocation is to be implemented. The report includes a Functional Hazard Analysis (FHA). The FHA is done to see if the applications for TIS-B are ready for implementation or if more hazard preventing actions has to be taken, before any operational actions can be performed. The report also involves a theoretical introduction to Air Traffic Management (ATM), Surveillance techniques and TIS-B. All parts included in the report results in conclusions and recommendations regarding the TIS-B service.
