Abstract
(EN)
A short distance wireless data transmission system and method which are capable of minimizing data loss are disclosed. The short distance wireless data transmission system can monitor variation amount of memory data, which is buffered in the master side when data transmission errors occur, can perform re-transmission of data having transmission errors, and can perform a change toward new replacement channel without interference if variation amount of memory data, which is buffered therein, exceeds a predetermined reference value to re-transmit from data in which the first transmission error occurs thereto, such that real time data cannot be lost, although a channel change is generated by successive channel interference.
(FR)
La présente invention concerne un procédé et un système de transmission de données sans fil courte distance permettant de réduire la perte de données. Le système de transmission de données sans fil courte distance est conçu pour surveiller la quantité de variation des données mémoire qui sont mises en mémoire tampon côté maître en cas d'erreurs de transmission de données, et pour exécuter une modification en apportant une nouvelle voie de remplacement sans brouillage si la quantité de variation des données mémoire mises en mémoire tampon dépasse une valeur de référence prédéterminée pour retransmettre les données dans lesquelles ont eu lieu les erreurs, de telle sorte que les données en temps réel ne peuvent pas être perdues, bien qu'une modification de voie soit générée par des brouillages de voie successifs.
