Title
(EN) DIVERSITY SYNCHRONOUS CONNECTION-ORIENTED AUDIO CONNUNICATION MODES
(FR) MODES DE COMMUNICATION AUDIO ORIENTES CONNEXION SYNCHRONE DE DIVERSITE
Abstract
(EN) The diversity SCO digital audio technique (300) provides packet protection through statistical diversity by adding new audio modes (202, 204) that operate within a Bluetooth framework (200). Increased packet protection improves audio intelligibility and data transmission. The combination of a blind or signaled transmission of a redundant packet (202 or 204) in combination with a randomly faded frequency hop for each packet provide for enhanced reliability and link quality.
(FR) La technique audionumérique SCO de diversité (300) assure une protection de paquets par la diversité statistique en ajoutant de nouveaux modes audio (202, 204) qui fonctionnent dans une architecture Bluetooth (200). La protection de paquets accrue améliore l'intelligibilité audio ainsi que la transmission de données. La combinaison d'une transmission signalée ou sans accusé de réception d'un paquet redondant (202 ou 204) et d'un saut de fréquence à évanouissement aléatoire pour chaque paquet assure une meilleure qualité de liaison et une plus grande fiabilité.
