Abstract

Selon la présente invention, un serveur vidéo (100) code un flot de données vidéo conformément aux valeurs de certains paramètres et envoie le flot de données vidéo sur un réseau (200) à un client vidéo (200) qui décode le flot de données vidéo reçu pour que ces données soit présentées à un utilisateur. A la réception du flot de données vidéo, le client vidéo (200) réunit en continu les données concernant au moins l'état du réseau (200) et envoie ces données au serveur vidéo (100). Ce serveur vidéo (100) modifie les valeurs des paramètres sur la base des données reçues du client vidéo (200) qui, à son tour, modifie le codage du flot de données vidéo.
