Abstract

L'invention concerne un serveur de poste de police qui copie des données vidéo de preuve (mo1) en tant que données source, transcode les données vidéo de preuve (mo1) qui sont obtenues par la copie, en générant des données vidéo de preuve conformes (mc1) qui sont conformes à un format standard, et transmet ces dernières à un serveur de quartier général. Le serveur de poste de police stocke les données vidéo de preuve (mo1) dans un stockage à froid (31). Le serveur de quartier général stocke dans un stockage à chaud (11) les données vidéo de preuve conformes (mc1) qui ont été transmises par le serveur de poste de police, et transmet les données vidéo de preuve conformes (mc1) à un ordinateur personnel d'agence de réception (65) d'une agence de réception telle qu'un tribunal ou un bureau de procureur.
