Hello Wolfy Here's the answer from TDF - - - - Hello, Since January 1, we have been carrying out new DRM tests from our Issoudun distribution center. These tests are initiated by TDF as part of our DRMCast project. DRMCast is an OC receiver that we have developed on our own funds which makes it possible to locally rebroadcast DRM content over wifi. Through this gateway-type interface, any smartphone or tablet-type receiver is thus capable of receiving sound, text and images broadcast in DRM. The first tests were carried out on the minitransat in 2019 with a race report for boats crossing the Atlantic. We are not far enough advanced to date to address Vendée Globle type races, but the Maritime world is a track that we are considering for DRMCast. For the time being, we have 4 30-minute broadcasting slots with RFi world programs and some associated data: 13: 00-13:30 11735 15: 00-15:30 9905 17: 30-18:00 9905 23: 30-00:00 5875 These slots are likely to change in the days / weeks to come. These are tests to continue our development, we are not communicating at the moment. - - - - Bonjour, Nous réalisons depuis le 1er janvier de nouveaux tests en DRM depuis notre centre de diffusion d’Issoudun. Ces tests sont à l’initiative de TDF dans le cadre de notre projet DRMCast. DRMCast est un récepteur OC que nous avons développé sur fonds propres qui permet de rediffuser localement un contenu DRM en wifi. Par cette interface du type gateway n’importe quel récepteur de type smartphone, tablette est ainsi capable de recevoir son, texte et image diffusés en DRM. Des premiers tests ont été réalisés sur la minitransat en 2019 avec un bulletin course vers les bateaux qui traversaient l’atlantique. Nous ne sommes pas assez avancés à ce jour pour adresser des courses de type Vendée Globle, mais le monde Maritime est une piste que nous envisageons pour DRMCast. Pour l’heure nous avons 4 créneaux de 30mn de diffusion avec les programme RFi monde et quelques données associées : 13:00-13:30 11735 15:00-15:30 9905 17:30-18:00 9905 23:30-00:00 5875 Ces créneaux sont susceptibles de changer dans les jours/semaines à venir il s’agit ici de tests pour poursuivre nos développements, nous ne faisons pas de communication pour le moment. No problem for the translation ? Bis bald ! Jean-Michel Le samedi 23 janvier 2021 à 08:47:14 UTC+1, Wolfgang Bueschel_DF5SX a écrit : google_translator:
Developper, pour la Marine nationale, des transmissions hautes frequences discretes sur longues distances
Cher Jean-Michel, je voudrais vous demander des informations détaillées sur les tests ISSoudun DRM: qui initie ces diffusions? Le Département de la Défense de la Marine, la TDF, ou est-ce un service radio français régulier de la RFI ? salutations de Stuttgart, Bonne année 2021, restez toujours en bonne santé. vy73 wolfie https://www.wwdxc.de/topnews.shtml FRANCE Developper, pour la Marine nationale, des transmissions hautes frequences discretes sur longues distances.
