    • PURPOSE: To continue communication without executing processing for setting a communicating party again even when a node ID is changed by bus reset or the like. CONSTITUTION: When it is decided that bus reset is generated in a step S41, the procedure is advanced to a step S42, and stored specific information (for example, a node unique ID) is read in advance. The specific information of each electronic equipment connected with the IEEE1394 bus is obtained in a step S43, and whether the obtained specific information of each electronic equipment matched with the read specific information is present is decided in a step S44, and when it is decided that matching specific information is present, the procedure is advanced to a step S45. Then, the electronic equipment having the specific information in matching with the stored specific information is used as a communicating party, and the node ID is read, and the communication of data is resumed following a state before the generation of the bus reset.
    • 目的:即使通过总线复位等改变节点ID,也可以继续进行通信而不执行用于设定通信对方的处理。 构成:当在步骤S41中确定生成总线复位时,该过程前进到步骤S42,并且预先读取存储的特定信息(例如,节点唯一ID)。 在步骤S43中获得与IEEE1394总线连接的每个电子设备的具体信息,并且在步骤S44中确定所获得的与所读取的特定信息相匹配的每个电子设备的特定信息是否存在,并且当确定 存在匹配的特定信息,该过程进行到步骤S45。 然后,将具有与存储的特定信息匹配的特定信息的电子设备用作通信方,并且读取节点ID,并且在总线复位生成之前的状态之后重新开始数据通信。
