  However, the prior art requires a display output function of external information in the display device, and this function may not be realized particularly in a general-purpose display device.

  An object of the present invention is to perform recording / reproduction to display that an event has occurred in the first processing unit even when the display is performed on the display device by the second processing unit while using a general-purpose display device. To provide an apparatus.

  According to one aspect of the present invention, a first processing unit including a signal processing unit for processing video data, a signal processing unit for processing video data, and video data processed by the signal processing unit are displayed. Display processing means for outputting to the second processing means configured to be independent of the first processing means, and an event has occurred in the first processing means, indicating that the event has occurred. Recognizing whether or not video data output by the display output means included in the second processing means is displayed on an external display device, detecting that a message for notification has occurred The video data output by the display output means is displayed on the external display device when it is detected that the message is generated by the recognition means and the detection means. The display requesting means for requesting the second processing means to display that the message detected by the detecting means has occurred, and the display requesting means. There is provided a recording / reproducing apparatus comprising alternative display output means for outputting data indicating that the message detected by the detection means has occurred when requested.

  According to the present invention, it is possible to display that an event has occurred in the first processing unit even when a display is performed on the display device by the second processing unit while using a general-purpose display device. It becomes possible.

  Embodiments of the present invention will be described below with reference to the drawings.

  First, the configuration of the recording / reproducing apparatus 10 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of a recording / reproducing apparatus 10 according to the present embodiment.

  The recording / reproducing apparatus 10 is configured to control recording and reproducing operations of video data such as a broadcast program, for example, according to a remote control code transmitted by an infrared signal from a remote control unit (not shown).

  As shown in FIG. 1, the recording / reproducing apparatus 10 includes a first processing unit 11, a second processing unit 12, a storage unit 13, and a display switching unit 14.

  In the present embodiment, the first processing unit 11 is realized as a recording / playback processing unit 11 that records or plays back video data. The second processing unit 12 is realized as a reproduction processing unit 12 that reproduces video data.

  In addition, the recording / playback processing unit (first processing unit) 11 and the playback processing unit (second processing unit) 12 are configured independently, and the monitor device 20 provided outside the recording / playback device 10 is provided. Share. Normally, either the recording / playback device processing unit 11 or the playback processing unit 12 occupies the monitor device 20 and can switch the occupancy to each other by a user operation, for example.

  The recording / playback processing unit 11 acquires video data from, for example, a medium and executes processing for playing back the video data. In addition, the recording / playback processing unit 11 executes a process of recording video data such as a broadcast program converted into a compression-coded digital data sequence in, for example, the storage unit 13. The recording / playback processing unit 11 includes a microcomputer (hereinafter referred to as a microcomputer) unit 111, a signal processing unit 112, and a display output unit 113.

  The microcomputer unit 111 controls the operation of each component of the recording / playback processing unit 11. The microcomputer unit 111 includes a memory 111a that stores various programs, for example. The microcomputer unit 111 has a function of recognizing which one of the recording / playback processing unit 11 and the playback processing unit 12 occupies the monitor device 20. The microcomputer unit 111 detects that an event has occurred in the recording / playback processing unit 11 and, as a result, a message has been generated to notify the user that the event has occurred. For example, in the recording process by the recording / playback processing unit 11, the event is stopped due to a certain cause.

  The microcomputer unit 111 also has a function of requesting the reproduction processing unit 12 to display the occurrence of the message when the recording / reproduction processing unit 11 detects that the message has occurred. At this time, the microcomputer unit 111 determines whether to request display according to the level of the generated message. The level is preset for each message and indicates the importance of the message. Details of this level will be described later.

  The signal processing unit 112 executes processing for recording or reproducing video data under the control of the microcomputer unit 111. The signal processing unit 112 is, for example, a decoding process for decoding compressed and encoded video data, or an encoding process for digitally compressing and encoding broadcast program video data input from a tuner unit (not shown), for example. Execute.

  The display output unit 113 outputs the video data processed by the signal processing unit 112 to, for example, the display switching unit 14. The display output unit 113 also outputs data indicating a message for notifying the user of an event that has occurred in the recording / playback processing unit 11.

  For example, the reproduction processing unit 12 acquires video data from a medium and executes processing for reproducing the video data. The reproduction processing unit 12 includes a microcomputer unit 121, a signal processing unit 122, and a display output unit 123.

  The microcomputer unit 121 controls the operation of each component of the reproduction processing unit 12. The microcomputer unit 121 includes a memory 121a for storing various programs, for example. The microcomputer unit 121 has a function of recognizing which one of the recording / reproduction processing unit 11 and the reproduction processing unit 12 occupies the monitor device 20.

  The signal processing unit 122 executes processing for reproducing video data under the control of the microcomputer unit 121. The signal processing unit 122 performs a decoding process for decoding, for example, compression-encoded video data.

  The display output unit 123 outputs the video data processed by the signal processing unit 122 to the display switching unit 14 in order to display the video data on the monitor device 20, for example. When the microcomputer 111 requests that the recording / playback processing unit 11 display that a message has been generated, the display output unit 123 outputs data indicating that the message has occurred to the display switching unit 14. . That is, the display output unit 123 outputs data for displaying (substituting display) the occurrence of a message in the recording / playback processing unit 11 instead of the recording / playback unit 11.

  The storage unit 13 is a hard disk drive unit that executes a process of recording video data converted into a compression-encoded digital data string or a process of reading recorded video data under the control of the microcomputer unit 111 or the microcomputer unit 121 including.

  Further, the storage unit 13 includes an optical disk drive unit that executes a read / write process on a recording medium D such as a DVD-RAM / DVD-R. For example, a DVD (Digital Versatile Disc) drive, which is an example of an optical disk drive, can also execute data read processing from a recording medium such as a DVD-ROM medium.

  The display switching unit 14 switches the processing unit that occupies the monitor device 20, that is, the recording / reproduction processing unit 11 or the reproduction processing unit 12, according to a remote control code transmitted by an infrared signal or the like, for example, operated by a user. At this time, the display switching unit 14 does not affect the operation of the recording / playback processing unit 11 or the playback processing unit 12. That is, for example, even when the occupation of the monitor device 20 is switched from the recording / playback processing unit 11 to the playback processing unit 12, the processing by the recording / playback processing unit 11 is executed.

  Further, the display switching unit 14 monitors data output by the display output unit (display output unit 113 or display output unit 123) of the processing unit (recording / reproduction processing unit 11 or reproduction processing unit 12) that occupies the monitor device 20. Output to the device 20.

  For example, when various data output by the display output unit 113 of the recording / playback processing unit 11 are displayed on the monitor device 20, when the display switching unit 14 switches the occupation of the monitor 20 to the playback processing unit 12, For example, video data output by the display output unit 123 of the reproduction processing unit 12 is displayed on the monitor device 20.

  Next, an alternative display processing procedure by the recording / reproducing apparatus 10 and an example of display on the monitor apparatus 20 will be described with reference to the flowchart of FIG.

  First, for example, when the user operates the recording / playback processing unit 11, for example, the playback-processed data output by the display output unit 113 of the recording / playback processing unit 11 is displayed on the monitor device 20 (step S1). At this time, the recording / reproducing processor 11 occupies the monitor device 20. The microcomputer unit 111 of the recording / playback processing unit 11 recognizes that the recording / playback processing unit 11 occupies the monitor device 20.

  Next, for example, when the user performs an operation of switching the occupation of the monitor device 20, the display switching unit 14 switches the occupation of the monitor from the recording / reproduction processing unit 11 to the reproduction processing unit 12 (step S2). Therefore, for example, when the user operates the reproduction processing unit 12, data output by the display output unit 123 of the reproduction processing unit 12 is displayed on the monitor device 20 (step S3). At this time, the microcomputer unit 121 of the reproduction processing unit 12 recognizes that the reproduction processing unit 12 occupies the monitor device 20.

  Here, it is assumed that an event has occurred in the recording / reproducing processor 11 regardless of the reproducing processor 12 (step S4). At this time, a message for notifying the user that the event has occurred is generated. The microcomputer unit 111 of the recording / playback processing unit 11 detects that this message has occurred. When the microcomputer unit 111 detects that a message has been generated, the display output unit 113 of the recording / playback processing unit 11 outputs the message to the display switching unit 14. In this case, since the monitor device 20 is occupied by the reproduction processing unit 12, the display switching unit 14 does not output the above message to the monitor device 20. That is, the message is not displayed on the monitor device 20.

  Next, the microcomputer unit 111 confirms the level of the message generated by the recording / playback processing unit 11 (step S5). The message level is preset and stored in the memory 111 a in the microcomputer unit 111.

  The level indicates the importance of the message for notifying the user of the event. This level is set according to whether or not the message is displayed until it is confirmed by the user, for example, when the message is displayed on the monitor device 20, for example. For example, a message displayed until it is confirmed by the user is set to a high level, and a message that is not confirmed by the user, for example, is deleted in about several seconds, is set to a low level. Note that the confirmation by the user is notified to the recording / reproducing apparatus 10 when, for example, an “OK” button displayed near the message is pressed (selected) by the user.

  The microcomputer unit 111 determines whether or not to request the reproduction processing unit 12 to display that the detected message has occurred according to the level of the message generated by the recording / reproduction processing unit 11 ( Step S6).

  The microcomputer unit 111 requests the reproduction processing unit 12 to display when the level of the message generated by the recording / reproduction processing unit 11 is high (step S7). When the reproduction processing unit 12 receives the request, the display output unit 123 of the reproduction processing unit 12 outputs data indicating that a message has occurred in the recording / reproduction processing unit 11 to the display switching unit 14. In this case, the display switching unit 14 outputs the data output by the display output unit 123 to the monitor device 20 (step S8). Thereby, it is possible to substitute display that the message has occurred in the recording / playback processing unit 11.

  In step S6, when the level of the detected event is low, no request is made to the reproduction processing unit 12. Therefore, the alternative display process by the recording / reproducing apparatus 10 is not performed.

  Here, FIG. 3 shows an example of the display screen 200 of the monitor device 20 when data indicating that a message is generated in the recording / playback processing unit 11 is output by the display output unit 123 and displayed on the monitor device 20. It is.

  As shown in FIG. 3, when data indicating that a message has occurred in the recording / playback processing unit 11 is output from the display switching unit 14 to the monitor device 20, for example, a title name or the like is displayed on the display screen 200. An icon 201 is displayed near the area. This icon 201 indicates that a message has occurred in the recording / playback processing unit 11. By confirming this icon 201, the user can recognize that a message has occurred on the recording / playback processing unit 11 side.

  Returning again to FIG. 2, when the icon 201 as shown in FIG. 3 is displayed on the display screen of the monitor device 20, for example, the display switching unit 14 occupies the monitor device 20 by the user's operation. Is switched to the recording / reproduction processing unit 11 (step S9), the reproduction processing unit 12 erases the icon 201 described above. Then, the data output by the display output unit 113 of the recording / playback processing unit 11 is displayed on the monitor device 20. At this time, the display output unit 113 outputs a message for notifying an event that has occurred in the recording / playback processing unit 11 as described above, so that the message is displayed on the monitor device 20 (step S10). .

  When a message for notifying an event that has occurred in the recording / playback processing unit 11 displayed on the monitor device 20 is confirmed by the user, the message is deleted, and the recording / playback device 10 ends the alternative display processing.

  FIG. 4 shows an example of a display screen 200 of the monitor device 20 on which a message for notifying an event that has occurred in the recording / playback processing unit 11 is displayed. Here, the event that has occurred in the recording / playback processing unit 11 will be described as the fact that, for example, the recording could not be performed because the recording medium capacity was insufficient when the recording was started by the recording reservation.

  In this case, as shown in FIG. 4, the display screen 200 indicates that “the recording reservation start time has been reached, but it could not be executed due to lack of capacity”. An “OK” button 202 for notifying the apparatus 10 is displayed. By confirming such a screen, the user can recognize what event has occurred on the recording / playback processing unit 11 side. Further, when the user ends the confirmation and selects the “OK” button 202, the message is deleted.

  Next, the flow of alternative display processing among the user, the recording / playback processing unit 11, the playback processing unit 12, and the monitor device 20 will be described with reference to FIG.

  First, it is assumed that the user has performed an operation of switching the display on the monitor device 20 to the recording / playback processing unit 11 by using, for example, a remote control unit (step S11). At this time, it is assumed that the user has also performed an operation for operating the recording / playback processing unit 11.

  In this case, a signal for switching the display of the monitor device 20 to the recording / reproduction processing unit 11 and a signal for operating the recording / reproduction processing unit 11 are notified from the remote control unit to the recording / reproduction device 10 (step S12). Then, the recording / reproducing processor 11 starts its operation (step S13), and the display on the monitor device 20 is switched to the recording / reproducing processor 11. When the recording / reproduction processing unit 11 operates, the display output unit 113 of the recording / reproduction processing unit 11 monitors, for example, video data processed by the signal processing unit 112 of the recording / reproduction processing unit 11 via the display switching unit 14. 20 (step S14). The data output by the display output unit 113 of the recording / playback processing unit 11 is displayed on the monitor device 20 (step S15).

  Next, as in step S11, it is assumed that an operation for switching from the recording / playback processing unit 11 to the playback processing unit 12 is performed by the user (step S16). At this time, it is assumed that the user has also performed an operation for operating the reproduction processing unit 11.

  In this case, a signal for switching the display of the monitor device 20 to the reproduction processing unit 12 and a signal for operating the reproduction processing unit 12 are notified from the remote control unit, for example, to the recording / reproduction device 10 (step S17). Then, the reproduction processing unit 12 starts operation (step S18), and the display on the monitor device 20 is switched to the reproduction processing unit 12. At this time, the display of the monitor device 20 is switched from the recording / playback processing unit 11 to the playback processing unit 12, but the operation of the recording / playback processing unit 11 is not interrupted unless an interruption operation is performed by the user.

  When the playback processing unit 12 operates, the display output unit 123 of the playback processing unit 12 sends the video data processed by the signal processing unit 122 of the playback processing unit 12 to the monitor device 20 via the display switching unit 14. Output (step S19). In the monitor device 20, the data output by the display output unit 123 of the reproduction processing unit 12 is displayed (step S20).

  Here, an event occurs independently within the recording / playback processing unit 11 regardless of the playback processing unit 12, and the recording / playback processing unit 11 detects that a message for notifying the user of the event has occurred (step S21). ). At this time, the recording / playback processing unit 11 outputs a message (data indicating) to the display switching unit 14 to notify the user (step S22). However, since the playback processing unit 12 currently occupies the display of the monitor device 20, the message is not displayed on the monitor device 20.

  The microcomputer unit 111 of the recording / playback processing unit 11 checks the level of a message generated in the recording / playback processing unit 11 and determines whether or not the playback processing unit 12 should be notified (request for display) that the message has occurred. Determination is made (step S23).

  At present, the display on the monitor device 20 is displayed by the playback processing unit 12, so that if the message generated in the recording / playback processing unit 11 is a message to be notified to the playback processing unit 12, playback is performed from the recording / playback processing unit 11. The processing unit 12 is requested to display that a message has occurred in the recording / playback processing unit 11 (step S24).

  When a request is notified from the recording / playback processing unit 11 to the playback processing unit 12, the playback processing unit 12 receives data (alternative display data) indicating that a message has occurred in the recording / playback processing unit 11 in accordance with the notification. It outputs to a monitor apparatus via the display switching part 14 (step S25, 26). Then, an alternative display as shown in FIG. 3 is displayed on the monitor device 20 (step S27).

  When the user performs an operation to switch the display of the monitor device 20 from the playback processing unit 12 to the recording / playback processing unit 11 in the state where the alternative display is performed (step S28), the display for switching the monitor device 20 is switched. A signal is notified to the recording / reproducing apparatus 10 (step S29). Then, the display of the entire recording / reproducing apparatus 10 is switched to video data output by the display output unit 113 of the recording / reproducing processing unit 11. At this time, the alternative display data is erased by the reproduction processing unit 12 (step S30). When the display of the monitor device 20 is switched to the recording / playback processing unit 11, the recording / playback processing unit 11 has already output a message to the display switching unit 14 in step S 22, so that the message is displayed on the monitor device 20. (Step S31). Therefore, the user can check the message displayed on the monitor device 20.

  As described above, in the present embodiment, when the display by the playback processing unit 12 is performed on the monitor device 20, the playback processing unit replaces the recording / playback processing unit 11 with respect to an event that has occurred in the recording / playback processing unit 11. It becomes possible for 12 to display that instead. Thus, the user can recognize that an event has occurred in the recording / playback processing unit 11 even while the playback processing unit 12 is displaying. Further, in the present embodiment, since the reproduction processing unit 12 performs display instead, it can be realized without the monitor device 20 having a special display output function, for example.

  In the present embodiment, it is determined whether or not an alternative display is requested according to the event level. For example, when a message for notifying an event is not displayed for 3 seconds or more, there is a high possibility that the message is not already displayed when the display is switched by the user even if the message is generated instead of being displayed. Therefore, for example, by performing an alternative display only for a message that is displayed for 3 seconds or more, it is possible to execute an alternative display only for an event that should be particularly confirmed by the user.

  In the present embodiment, it has been described that an alternative display, for example, the icon 201 is displayed on the display screen 200 of the monitor device 20, but the alternative display is displayed on a display unit provided in the main body of the recording / reproducing apparatus 10, for example. It does not matter as a configuration. Further, for example, a configuration may be adopted in which a user is notified as an audio output from an audio output device provided in the main body of the recording / reproducing apparatus 10. It is also possible to provide a display device dedicated for alternative display and display on the display device.

  Moreover, although the case where there are two processing units has been described in the present embodiment, the same applies to the case where there are three or more processing units. Even in this case, the alternative display can be performed by notifying the processing unit occupying the monitor device 20 that the event has occurred.

  Further, in the present embodiment, the case where the playback processing unit 12 performs alternative display of the occurrence of a message in the recording / playback processing unit 11 has been described. Conversely, the recording / playback processing unit 11 performs alternative display. It does not matter.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment.
