Abstract:
(EN) A camera 200 and accessory devices 100, 300 perform communication using channels which include a data communication channel that is used in data communication and a notification channel that notifies the timing of communication performed over the data communication channel. The accessory devices 100, 300 each switch from a first communication scheme to a second communication scheme in response to receiving, over the data communication channel in communication under the first communication scheme, communication counterpart designation data indicating that said accessory device has been selected as the communication counterpart of the camera 200.
(FR) Une caméra 200 et des dispositifs accessoires 100, 300 réalisent une communication à l'aide de canaux qui comprennent un canal de communication de données qui est utilisé dans une communication de données et un canal de notification qui notifie le moment de la communication effectuée sur le canal de communication de données. Les dispositifs accessoires 100, 300 commutent chacun d'un premier schéma de communication à un second schéma de communication en réponse à la réception, sur le canal de communication de données en communication sous le premier schéma de communication, de données de désignation de contrepartie de communication indiquant que ledit dispositif accessoire a été sélectionné en tant que contrepartie de communication de la caméra 200.
(JA) カメラ200とアクセサリ装置100、300は、データ通信に用いられるデータ通信チャネルとデータ通信チャネルを介して行う通信のタイミングを通知する通知チャネルとを含むチャネルを用いた通信を行う。アクセサリ装置100、300は、第1通信方式の通信において、カメラ200の通信相手として自身が選択されたことを示す通信相手指定データをデータ通信チャネルを介して受信したことに応じて、第1通信方式から第2通信方式への切り替えを行う。
