摘要： A device on the sending and playing device plays and outputs a content recorded to a recording medium on the sending side. A device on the receiving and recording side receives the played and outputted content and records it to a recording medium on the receiving side. The device on the sending and playing device erases the content recorded to the device on the sending and playing device based on recording-state information of the device on the receiving and recording side by using the sent played content. Thus, in move processing of a “Copy Once” content, it is possible to prevent the loss of content by the device on the sending and playing side when the device on the receiving and recording and side does not normally record the content.
摘要翻译：发送和播放设备上的设备播放并输出记录在发送侧的记录介质上的内容。接收和记录侧的设备接收播放并输出的内容并将其记录在接收侧的记录介质上。发送和播放设备上的设备通过使用发送的播放内容，基于在接收和记录侧的设备的记录状态信息来擦除记录在发送和播放设备上的设备的内容。因此，在“复制一次”内容的移动处理中，当接收和记录和设备不正常地记录内容时，可以防止发送和播放侧的设备丢失内容。
