  In the content movement process, the movement processing unit 20 transmits the content read from the hard disk H2 to the receiving-side recording / reproducing device RD1 via the digital interface DIF. The receiving-side recording / reproducing device RD1 records the received content on the hard disk H1, and the transmitting-side recording / reproducing device RD2 sequentially deletes the transmitted content from the hard disk H2.

  The movement processing unit 20 periodically inquires about the current state of the receiving-side recording / reproducing device RD1 when moving the content recorded on the hard disk H2 to the receiving-side recording / reproducing device RD1 via the digital interface DIF. The content recorded on the hard disk H2 is moved according to the current state of the recording / reproducing device RD1.

  The receiving-side recording / reproducing device RD1 includes a hard disk H1 as a storage medium for recording content, and a recording processing unit 10 that performs a recording process for recording content on the hard disk H1.

  The recording processing unit 10 of the receiving-side recording / reproducing device RD1 stores a first communication unit that receives digital data from the transmitting-side recording / reproducing device RD2, and stores the digital data received from the first recording / reproducing device in a hard disk H1 as a storage medium. And a second communication unit that receives a current state acquisition request for inquiring about the current device state from the transmission-side recording / reproducing device RD2 via the digital interface DIF, and a current device state as a response to the current state acquisition request And a third communication unit that transmits the first value or the second value according to the control unit, and an overall control unit CTR. The overall control unit CTR includes a first communication unit control unit CTR1 that controls the first communication unit, a second communication unit control unit CTR2 that controls the second communication unit, and a third communication unit control that controls the third communication unit.

  As shown in FIG. 2, the recording processing unit 10 of the receiving-side recording / reproducing device RD1 according to the present embodiment includes a transmission / reception interface unit TR as a first communication unit and a second communication unit. The transmission / reception interface unit TR is controlled by the first communication unit control unit CTR1 and the second communication unit control unit CTR2, and acquires digital data such as video signals and audio signals transmitted from the transmission-side recording / reproducing device RD2, and the current state Receive a request.

  As the third communication unit, the recording processing unit 10 is a current state information storage unit 101 that stores current device state information, and execution capability information that indicates whether or not the received content recording process is executable. Current state information conversion unit that outputs current device state information corresponding to current device state information stored in the storage unit 102, current state information storage unit 101, and execution availability information stored in the execution availability information storage unit 102 103, and a status acquisition request processing unit 104 that transmits the current device status information acquired from the current status information conversion unit 103 as a response to the current status acquisition request from other devices.

  In the current state information storage unit 101, current device state information is stored by the third communication unit control unit CTR3. In the executability information storage unit 102, executability information indicating that recording is possible when the receiving-side recording / reproducing device RD1 is capable of executing the received content recording process is performed by the third communication unit control unit CTR3. To be recorded.

  In addition, when the receiving-side recording / reproducing device RD1 is in a state in which the received content recording process cannot be performed, the third communication unit control unit CTR3 receives execution permission information indicating that recording is impossible. 102.

  In the current state information conversion unit 103, for example, when the execution requested information stored in the execution availability information storage unit 102 can execute the requested process, the current device stored in the current state information storage unit 101 Output information based on status information.

  When the execution status information stored in the execution status information storage unit 102 indicates that the requested process cannot be executed, the current status information conversion unit 103 stores the current status information conversion unit 103 in the current status information storage unit 101. Regardless of the current device status information, information indicating that the requested process cannot be executed is output.

  In the present embodiment, the current state information conversion unit 103 stores the current device stored in the current state information storage unit when the recording unit 106 cannot store the content received from the transmission-side recording / playback device RD2 in the hard disk. Regardless of the state, the content recording process is converted into information that cannot be executed as a response to the current state acquisition request from the transmission-side recording / reproducing device RD2.

  The state acquisition request processing unit 104 transmits the device information acquired from the current state information conversion unit 103 to the transmission-side recording / reproducing device RD2 via the transmission / reception interface unit TR. The movement processing unit 20 of the transmitting-side recording / reproducing device RD2 receives the response from the receiving-side recording / reproducing device RD1, and does not execute the content transmission because the received response is in a state where the content recording process cannot be performed. .

  As shown in FIG. 3, for example, the movement processing unit 20 receives a response from the reception-side recording / reproducing device RD1 and the receiving-side recording / reproducing device RD1 is turned off or the recording medium state is no medium. Does not execute content transmission.

  The recording processing unit 10 further includes a control request processing unit 105 and a recording unit 106 as recording units. The control request processing unit 105 receives a control request from the transmission side recording / reproducing device RD2. When receiving a control request from the transmission-side recording / reproducing device RD2, the control request processing unit 105 refers to the execution availability information stored in the execution availability information storage unit 102 and is in a state where the received content recording process can be executed at present. In this case, a response indicating that the control request has been received is sent back to the transmitting-side recording / reproducing device RD2 using the transmission / reception interface unit TR, and the control request content is notified to the overall control unit CTR. When receiving the control request, the overall control unit CTR controls the recording unit 106 to record the received content on the hard disk H1.

  The control request processing unit 105 refers to the execution availability information stored in the execution availability information storage unit 102, and when it is currently impossible to execute, transmits a notification that the request from the transmission-side recording / reproducing device RD2 cannot be received. To the side recording / reproducing device RD2.

  Next, the operation of the recording / reproducing apparatus according to the present embodiment will be described with reference to the drawings. A case will be described in which the user copies or moves the content recorded on the transmission-side recording / reproducing device RD2 to the reception-side recording / reproducing device RD1 connected via the digital interface DIF.

  The content transmitted by the transmission-side recording / reproduction device RD2 is received by the reception-side recording / reproduction device RD1, and recorded on a storage medium inside the reception-side recording / reproduction device RD1, such as the hard disk H1.

  That is, as shown in FIGS. 4A and 4B, the overall control unit CTR stores the current device status information in the current status information storage unit 101 (STA1). Similarly, whether or not content reception and content recording can be accepted, and whether or not the processing can be continued when these processes are being executed, is executed as current execution availability information. 102 (STA2).

  The transmission-side recording / reproducing device RD2 transmits a control request for starting the dubbing process or the moving process in order to dubb or move the content. The control command transmitted from the transmission-side recording / reproduction device RD2 is received by the transmission / reception interface unit TR of the reception-side recording / reproduction device RD1, and processed by the control request processing unit 105 (STA3).

  In the recording / reproducing system according to the present embodiment, a command group defined on the IEEE 1394, which is a digital interface DIF, is defined by an AV / C (Audio Video / Control) command defined on the IEEE 1394 standard. The command is adopted.

  The control request processing unit 105 refers to the execution availability information stored in the execution availability information storage unit 102 (STA4), and determines whether or not the requested recording / reproduction device RD1 can execute the requested process (step S4). STA5). If the requested process is currently executable, the control unit CTR responds to the requesting transmission-side recording / reproducing device RD2 using the transmission / reception interface unit TR and notifies the overall control unit CTR that the control request has been accepted. The request contents are notified (STA6).

  The control request processing unit 105 refers to the execution availability information stored in the execution availability information storage unit 102, and indicates that the request cannot be accepted if the requested process is currently unexecutable. To the transmitting side recording / reproducing apparatus RD2 (STA7).

  When the overall control unit CTR receives a request from the transmission-side recording / reproduction device RD2, the content is transmitted from the transmission-side recording / reproduction device RD2. The overall control unit CTR causes the transmission / reception interface unit TR to receive the transmitted content, and causes the recording unit 106 to start recording on the hard disk H1 (STA8).

  If the receiving-side recording / reproducing device RD1 determines that the content transmitted from the transmitting-side recording / reproducing device RD2 is not a certain time before the reserved recording time during recording (STA9), the recording on the content is completed (STA10). ).

  If the receiving-side recording / reproducing device RD1 determines that the content transmitted from the transmitting-side recording / reproducing device RD2 is a certain time before the reserved recording time during recording (STA9), the dubbing process or the moving process cannot be continued. Is stored in the executable information storage unit 102 as executable information (STA11).

  During the received content recording process of the receiving side recording / reproducing device RD1, the transmitting side recording / reproducing device RD2 periodically issues a current state acquisition request of the receiving side device to the receiving side recording / reproducing device RD1.

  The current state acquisition request command transmitted from the transmission-side recording / reproducing device RD2 is received by the transmission / reception interface unit TR (STA12). The current state acquisition request command received by the transmission / reception interface unit TR is processed by the state acquisition request processing unit 104 (STA13).

  The state acquisition request processing unit 104 acquires current state information from the current state information conversion unit 103. That is, the current state information conversion unit 103 refers to the execution availability information stored in the execution availability information storage unit 102 (STA14).

  If it is determined that the requested processing can be executed, the current state information conversion unit 103 acquires the current state information stored in the current state information storage unit 101 and directly proceeds to the state acquisition request processing unit 104. Send. The state acquisition request processing unit 104 transmits the current state information acquired from the current state information conversion unit 103 to the transmission-side recording / reproducing device RD2 using the transmission / reception interface unit TR.

  In the recording / reproducing apparatus according to the present embodiment, as current state information, as shown in FIG. 3, for example, a power state (ON / OFF), a mechanical operation state (recording / stopped / reproducing, etc.), storage medium state ( Media type / writable / no media etc.) and the current value of the time counter are used as attributes.

  When the transmission side recording / reproducing apparatus RD2 detects an abnormality in the response content of the reception side recording / reproducing apparatus RD1, the transmission side recording / reproducing apparatus RD2 stops the transmission of the content and executes the dubbing cancel process. If there is no problem with the response content of the receiving side recording / reproducing device RD1, the transmitting side recording / reproducing device RD2 normally performs the content dubbing or moving process to the end.

  When content is transmitted and received between the receiving-side recording / reproducing device RD1 and the transmitting-side recording / reproducing device RD2 connected by the digital interface DIF, the scheduled recording start time set by the user in the receiving-side recording / reproducing device RD1 If it is approaching, it is necessary to notify the receiving-side recording / reproducing apparatus RD1 that the transmitting-side recording / reproducing apparatus RD2 wants to be stopped by some method.

  However, conventionally, it has been difficult to interrupt transmission / reception processing when a command for requesting execution stop to the transmission-side recording / reproducing device RD2 is not defined in the control command group defined on the digital interface DIF. . On the other hand, in the present embodiment, as described below, the receiving-side recording / reproducing device RD1 performs a scheduled recording process having a higher priority than the received content recording process.

  While the receiving side recording / reproducing device RD1 is dubbing or moving, the transmitting side recording / reproducing device RD2 periodically issues a current state acquisition request of the receiving side recording / reproducing device RD1 to the receiving side recording / reproducing device RD1. The status acquisition request command is received by the transmission / reception interface unit TR (STA12). The received status acquisition request command is processed by the status acquisition request processing unit 104 (STA13).

  The current state information conversion unit 103 that passes the current state information to the state acquisition request processing unit 104 refers to the execution availability information stored in the execution availability information storage unit 102 (STA14). At this time, since the start time of the reserved recording with higher priority is approaching, the execution availability information is information indicating that the execution cannot be continued by the overall control unit CTR.

  Therefore, the current state information conversion unit 103 determines that the requested process cannot be executed, and does not output the information stored in the current state information storage unit 101 to the state acquisition request processing unit 104 as it is. Even if it does not occur, the abnormal value is output to the state acquisition request processing unit 104 (STA15).

  The current state information output from the current state information conversion unit 103 is transmitted to the state acquisition request processing unit 104, and is returned from the state acquisition request processing unit 104 to the transmission-side recording / reproducing device RD2 via the transmission / reception interface unit TR. (STA16).

  When the current state information conversion unit 103 converts the content based on the information stored by the current state information storage unit 101 and the execution availability information stored in the execution availability information storage unit 102, the transmitting-side recording / reproducing device RD2 Treats the receiving-side recording / reproducing device RD1 as being in an abnormal state, and converts the attribute included in the current state information into an abnormal value that cancels the content transmission process.

  For example, as shown in FIG. 3, the power state is OFF, the mechanical operation state is stopped, and the storage medium state is a value such as no medium. When these pieces of information are received as a response from the receiving-side recording / reproducing device RD1, the transmitting-side recording / reproducing device RD2 detects an abnormality from the response content of the receiving-side recording / reproducing device RD1. Therefore, the transmission-side recording / reproducing device RD2 stops the content transmission and executes a dubbing cancel process or the like.

  As a result, the receiving-side recording / reproducing device RD1 does not need to continue the content receiving process and the recording process, and can start reserved recording with higher priority than the content dubbing or moving process (STA17).

  In other words, conventionally, when a content is transmitted / received between recording / reproducing apparatuses connected by the digital interface DIF, a higher priority process such as start of reserved recording is performed in the receiving-side recording / reproducing apparatus RD1. If the command for requesting execution stop to the transmission-side recording / reproducing device RD2 is not defined in the control command group defined on the digital interface DIF, transmission / reception processing cannot be interrupted, and processing with higher priority is performed. I could not.

  However, as described above, when the processing cannot be continued in response to the current state acquisition request from the transmission-side recording / reproducing device RD2, the transmission-side recording / reproducing device RD2 interrupts the processing of the current state of the receiving-side recording / reproducing device RD1. Even if a process with higher priority occurs by providing a conversion unit 103 that performs conversion based on a conversion rule that causes a response and makes the status acquisition request processing unit 104 respond, RD2 can be directed to interrupt the current process.

  Therefore, according to the recording / reproducing apparatus, the recording / reproducing system, and the recording / reproducing method according to the present embodiment, even when the content transmitted from the transmitting-side recording / reproducing apparatus RD2 is being recorded in the receiving-side recording / reproducing apparatus RD1, more It is possible to provide a recording / reproducing apparatus, a recording / reproducing system, and a recording / reproducing method capable of executing processing with high priority.

  Further, as shown in FIG. 3, by storing abnormal values not only for one attribute but also for each attribute that can be inquired by the transmission-side recording apparatus RD2, the transmission-side recording apparatus RD2 can determine which one. Even when such a current state acquisition request is transmitted, it is possible to respond widely.

  Next, a recording / reproducing apparatus, a recording / reproducing system, and a recording / reproducing method according to a second embodiment of the present invention will be described below with reference to the drawings. In the following description, the same components as those of the recording / reproducing apparatus, the recording / reproducing system, and the recording / reproducing method according to the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.

  The configurations of the recording / reproducing apparatus and the recording / reproducing system according to the present embodiment are the same as the configurations of the recording / reproducing apparatus and the recording / reproducing system according to the first embodiment described above. That is, the recording / reproducing system according to the present embodiment includes the receiving-side recording / reproducing device RD1 and the transmitting-side recording / reproducing device RD2, and the receiving-side recording / reproducing device RD1 and the transmitting-side recording / reproducing device RD2 are digital interfaces. Connected by DIF.

  The recording / reproducing apparatus and the recording / reproducing method in the recording / reproducing system according to the present embodiment will be described below. As shown in FIGS. 5A, 5B, and 5C, the third communication unit control unit CTR3 stores the current device state in the current state information storage unit 101 as current state information (STB1).

  Similarly, whether or not content reception and content recording can be accepted, and whether or not these processes can be continued, is executed as current execution availability information. 102 (STB2).

  The transmission-side recording / reproducing device RD2 transmits a control request for starting the dubbing or moving process in order to dubb or move the content.

  The control command transmitted from the transmitting-side recording / reproducing device RD2 is received by the transmission / reception interface unit TR of the receiving-side recording / reproducing device RD1, and processed by the control request processing unit 105 (STB3).

  The control request processing unit 105 refers to the execution availability information stored in the execution availability information storage unit 102 (STB4), and determines whether or not the requested recording / reproduction device RD1 can execute the requested process (step S4). STB5).

  If the requested process is currently executable, the control unit CTR responds to the requesting transmission-side recording / reproducing device RD2 using the transmission / reception interface unit TR and notifies the overall control unit CTR that the control request has been accepted. The request contents are notified (STB6).

  The control request processing unit 105 refers to the execution availability information stored in the execution availability information storage unit 102, and indicates that the request cannot be accepted if the requested process is currently unexecutable. To the transmitting side recording / reproducing apparatus RD2 (STB7).

  When the overall control unit CTR receives a request from the transmission-side recording / reproduction device RD2, the content is transmitted from the transmission-side recording / reproduction device RD2. The overall control unit CTR causes the transmission / reception interface unit TR to receive the transmitted content, and causes the recording unit 106 to start recording on the hard disk H1 (STB8).

  If the receiving-side recording / reproducing device RD1 determines that the content transmitted from the transmitting-side recording / reproducing device RD2 is not a certain time before the scheduled recording time during recording (STB9), the recording of the content is completed (STB10). ).

  If the receiving-side recording / reproducing device RD1 judges that the content transmitted from the transmitting-side recording / reproducing device RD2 is being recorded for a predetermined time before the reserved recording time (STB9), the dubbing or moving process cannot be continued. The indicated information is stored in the executable information storage unit 102 as executable information (STB 11).

  During the received content recording process of the receiving side recording / reproducing device RD1, the transmitting side recording / reproducing device RD2 periodically issues a current state acquisition request of the receiving side device to the receiving side recording / reproducing device RD1.

  The current state acquisition request command transmitted from the transmission-side recording / reproducing device RD2 is received by the transmission / reception interface unit TR (STB12). The current status acquisition request command received by the transmission / reception interface unit TR is processed by the status acquisition request processing unit 104 (STB 13).

  The state acquisition request processing unit 104 acquires current state information from the current state information conversion unit 103. The current state information conversion unit 103 refers to the execution availability information stored in the execution availability information storage unit 102 (STB 14). In the recording / reproducing method in the recording / reproducing apparatus according to the present embodiment, since the start time of reserved recording having a higher priority is approaching than recording the content transmitted from the transmitting-side recording / reproducing apparatus RD2, the execution availability information is The information indicating that the execution cannot be continued is performed by the overall control unit CTR.

  For this reason, the current state information conversion unit 103 does not output the current state information stored in the current state information storage unit 101 to the state acquisition request processing unit 104 as it is, but an abnormality does not occur. A value indicating abnormality is output (STB15).

  Here, the current state information conversion unit 103 converts the value of the attribute of the time counter state in the current state information into identification information related to the content that has been interrupted during recording. This identification information includes identification information for uniquely identifying the target content, information on the position where recording was interrupted, and the like. The current state information conversion unit 103 acquires this identification information from the overall control unit CTR.

  The status acquisition request processing unit 104 returns the current status information acquired from the current status information conversion unit 103 to the requesting transmission-side recording / reproducing device RD2 via the transmission / reception interface unit TR (STB16).

  When the transmission side recording / reproducing device RD2 detects an abnormality in the response content of the reception side recording / reproducing device RD1, the transmission side recording / reproducing device RD2 cancels the content transmission and executes the dubbing cancel process. At this time, the interrupted content identification information included in the time counter state information received from the receiving-side recording / reproducing device RD1 is stored in the transmitting-side recording / reproducing device RD2.

  The receiving-side recording / reproducing device RD1 does not need to continue the content receiving process and the recording process any more, and can perform reserved recording with higher priority than the content recording process (STB17).

  Here, when the content movement process is interrupted, the content is divided into the hard disk H1 of the receiving-side recording / reproducing device RD1 and the hard disk H2 of the transmitting-side recording / reproducing device RD2.

  For example, if reservation recording starts at the receiving side recording / reproducing apparatus RD1 while moving a two-hour recorded program, the moved first half part (part A) is stored in the hard disk H1 of the receiving side recording / reproducing apparatus RD1. The latter half part (part B) that exists and has not been moved exists in the hard disk H2 of the transmission-side recording / reproducing device RD2.

  Therefore, when the scheduled recording is finished in the receiving recording / reproducing device RD1 and the content moving process can be resumed (STB18), in order to move the remaining content (part B) from the transmitting recording / reproducing device RD2, A control request to start the movement process is received (STB19). At this time, the control request from the transmitting-side recording / reproducing device RD2 includes the interrupted content identification information acquired from the receiving-side recording / reproducing device RD1.

  The control command received by the transmission / reception interface unit TR is processed by the control request processing unit 105 (STB 20). The control request processing unit 105 refers to the execution availability information stored in the execution availability information storage unit 102 (STB 21), and determines whether or not it is currently executable (STB 22).

  If the control request processing unit 105 determines that the requested process is currently executable, the control request processing unit 105 returns a response to the request source transmitting-side recording / reproducing device RD2 via the transmission / reception interface unit TR. And the control request contents are notified to the overall control unit CTR (STB 23).

  At this time, using the interrupted content identification information included in the control request, the overall control unit CTR searches for the content that has been dubbed or moved halfway in the past (part A), and the previously interrupted position (end of part A) ), The recording unit 106 is controlled so as to be connected (STB 24). After the recording of part B is completed, the overall control unit CTR performs a process of combining the part that has been recorded this time (part B) and the part that has been recorded last time (part B) (STB 25).

  By combining the content that has been processed (part A) and the remaining content (part B) as described above, even if the content movement processing is interrupted halfway, An execution result similar to that obtained when the movement is completed can be obtained.

  By performing such processing, it is possible to obtain the same effect as the recording / reproducing apparatus, recording / reproducing system, and recording / reproducing method according to the first embodiment described above, and it is also possible to execute reserved recording during dubbing. This also solves the problem of content transfer.

  That is, according to the recording / reproducing apparatus, the recording / reproducing system, and the recording / reproducing method according to the present embodiment, even if the content transmitted from the transmitting-side recording / reproducing apparatus RD2 is being recorded in the receiving-side recording / reproducing apparatus RD1, It is possible to provide a recording / reproducing apparatus, a recording / reproducing system, and a recording / reproducing method capable of executing processing with high priority.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. For example, in the recording / reproducing system according to the first embodiment and the second embodiment described above, an example using IEEE 1394 as a digital interface has been described. However, the present invention can be implemented with another digital interface having a similar control command system. Needless to say.

  In the recording / reproducing method according to the above-described embodiment, the receiving-side recording / reproducing device RD1 causes the transmitting-side recording / reproducing device RD2 to receive a predetermined time before a process with higher priority than the received content recording process is started. Although a command for canceling the content transmission has been returned, the device status information stored in the current status information storage unit 101 may be converted into information indicating an abnormality in accordance with operation information from the user. Even in this case, the same effects as those of the recording / reproducing apparatus, recording / reproducing system, and recording / reproducing method according to the above-described embodiment can be obtained.

  Further, during the dubbing or moving process, the recordable capacity of the hard disk H1 is measured, and when the capacity falls below a certain size, the execution status information is set as information indicating that the process cannot be continued. The recording / reproducing apparatus RD2 may be made to stop transmitting the content.

  In that case, the receiving-side recording / reproducing apparatus RD1 further includes means for measuring the recordable capacity of the hard disk H1, thereby being similar to the recording / reproducing apparatus, recording / reproducing system, and recording / reproducing method according to the above-described embodiment. An effect can be obtained.

  In the second embodiment, when the moving process is interrupted, the remaining content (part B) is connected from the interrupted content identification information to the interrupted position of the moved content (part A).
