摘要： According to one embodiment, there is disclosed a network apparatus making an information exchange with other apparatus on a network. A communication unit makes a communication with the other apparatus via the network. A data storage stores data. A recording bit rate measuring unit measures as a recording bit rate a decreasing amount per unit time of a residual capacity of the data storage. A recording bit rate monitor monitors the recording bit rate as a state variable, determines whether or not the state variable changes based on a predetermined reference, and outputs an event issue request if it is determined that the state variable changes. An event processor sends an event notification showing a state change from the communication unit to the other apparatus based on the event issue request from the recording bit rate monitor.

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.
