  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

(1) Configuration of Embodiment FIG. 2 is a block diagram showing a DVD player which is an optical disk reproducing apparatus according to an embodiment of the present invention. In the DVD player 1, the spindle motor 4 rotates the DVD 3 at a predetermined rotation speed under the control of the servo circuit 5. The optical pickup 6 is held by a thread mechanism (not shown) so as to move in the radial direction of the DVD 3 under the control of the servo circuit 5, irradiates the DVD 3 with a laser beam, receives the return light, and outputs the light reception result. The RF circuit 7 processes the light reception result by the optical pickup 6 so that the signal level changes according to the reproduction signal RF, the tracking error amount, and the focus error amount that change the signal level according to the pit formed on the DVD 3. A tracking error signal TE, a focus error signal FE, and the like are output. Under the control of the system control circuit 8, the servo circuit 5 controls the spindle motor 4 with various signals generated by the RF circuit 7, performs tracking control and focus control of the optical pickup 6, and further controls the optical pickup 6 to a predetermined value. Let the track seek.

  The signal processing circuit 9 reproduces a clock from the reproduction signal output from the RF circuit 7, and detects reproduction data by sequentially discriminating the binary reproduction signal using this clock. In addition, the reproduction data is deinterleaved and then error-corrected, thereby reproducing and outputting various data recorded on the DVD. The decoder 10 decompresses and outputs audio data and video data from the various data reproduced in this way. In the DVD player 1, video data and audio data output from the decoder 10 are output to the monitor device 11, whereby various contents recorded on the DVD 3 can be viewed.

  The synthesizing circuit 12 synthesizes the video signal output from the drawing circuit 13 with the video signal output from the decoder 10, and the drawing circuit 13 controls the video related to various menu screens under the control of the system control circuit 8. Generate and output a signal. As a result, the DVD player 1 can display various menu screens on the display screen of the monitor device 11, and can display icons and the like.

  The receiving circuit 14 receives a remote control signal output from the remote commander 15 and notifies the system control circuit 8, and in response to this, the remote commander 15 performs various remote controls in response to the operation of the operator by the user. The signal is transmitted by infrared rays, for example. As a result, the DVD player 1 can reproduce the DVD 3 by operating the remote commander 15. Specifically, as shown in FIG. 3, the remote commander 15 is provided with a power supply operation element 15A, a reproduction / pause operation element 15B, a guide operation element 15C, a joystick 15D, and the like. Thus, the operation of the DVD player 1 can be controlled.

  Thus, the system control circuit 8 is a computer that outputs a control signal to each part of the DVD player 1 by executing a processing procedure recorded in a memory (not shown), and by operating the operation element 16 provided in the DVD player 1, The operation of the entire DVD player 1 is controlled by the operation of the remote commander 15 by the remote control signal notified from the receiving circuit 14.

  That is, the system control circuit 8 instructs the power supply circuit (not shown) to start supplying power when the user instructs the power supply to be turned on by operating the operation element 16 or by operating the power supply operation element 15A in the remote commander 15. Thereby, the power source of the DVD player 1 is turned on. In addition, when the power is turned on in this way and the user instructs playback of the DVD 3 by the operation of the operation element 16 or by the operation of the reproduction / pause operation element 15B in the remote commander 15, the servo circuit 5 is operated. The video signal and the audio signal obtained by reproducing the DVD 3 are output to the monitor device 11.

  When the reproduction of the DVD 3 is started in this way, the system control circuit 8 obtains the navigation command data reproduced from the DVD 3 together with the video signal and the audio signal from the signal processing circuit 9, and the remote commander is analyzed by analyzing the navigation command. The specific operation by 15 is not accepted. Specifically, the system control circuit 8 selectively accepts an operation for the operator of the remote commander 15 so as not to accept an operation for a specific operator. Further, at this time, when the operator of the guide 15C is operated by the user, the operator that can selectively accept the operation is displayed on the display screen of the monitor device 11 by the control of the drawing circuit 13 in an on-demand manner. .

  That is, FIG. 1 is a flowchart showing a processing procedure of the system control circuit 8 according to such a navigation command. When the reproduction of the DVD 3 is started, the system control circuit 8 starts this processing procedure, moves from step SP1 to step SP2, and determines whether or not a navigation command has been acquired from the signal processing circuit 9. If a positive result is obtained here, the system control circuit 8 proceeds from step SP2 to step SP3 and analyzes the acquired navigation command. In step SP4, it is determined whether or not the guide operator 15C is pressed.

  If an affirmative result is obtained in step SP4, the system control circuit 8 moves from step SP4 to step SP5, and based on the analysis result of step SP3, guides of the manipulator usable by the control of the drawing circuit 13 are given to the monitor device 11. After the display, the process moves to step SP6. If a negative result is obtained in step SP4, or if a negative result is obtained in step SP2, the process proceeds directly to step SP6.

  Here, the system control circuit 8 determines whether or not the operator has been operated by the user. If a negative result is obtained here, the system control circuit 8 returns to step SP2. On the other hand, when the operator is operated by the user, the system control circuit 8 moves from step SP6 to step SP7, where the operator operated by this user is an operator that can be used by the analysis of step SP3. If a negative result is obtained here, the process returns to step SP2 without accepting the operation of the operator by the user.

  On the other hand, when the operator operated by the user is an operator permitted to be operated by the navigation command, the system control circuit 8 moves from step SP7 to step SP8 so as to correspond to the operation of this operator. After controlling the entire operation, the process returns to step SP2.

  As a result, in this embodiment, when a specific operation by the remote commander is not accepted, an operable operator is displayed on the display screen in response to a user instruction by operating the guide operator 15C. Thus, even a user who is unfamiliar with the user does not feel uncomfortable at all.

  FIG. 4 is a plan view showing the display screen of the monitor device 11 displayed in this way. This display screen shows a state in which the display of the playback time or the like is instructed by the user on the screen, and an operable operator is displayed in the area indicated by the symbol AR on the display screen. ing.

  The system control circuit 8 is configured to end such on-demand display when the guide operator is operated again by the user.

(2) Operation of the embodiment In the above configuration, in the DVD player 1, when the power is turned on and the user instructs the reproduction of the DVD 3, the spindle control, the track control, and the focus control are performed under the control of the servo circuit 5. In this state, the light pickup result of the return light obtained by irradiating the DVD 3 with the laser beam is detected by the optical pickup 6, and this light reception result is processed by the RF circuit 7 and the signal level changes according to the pit formed on the DVD 3. A reproduction signal RF to be obtained is obtained, and this reproduction signal RF is processed by the signal processing circuit 9. Also, the video data and audio data resulting from this processing result are decompressed by the decoder 10 and then output to the monitor device 11 via the synthesis circuit 12, thereby monitoring various contents based on the video data and audio data recorded on the DVD 3. It can be viewed with the device 11.

  In the state in which the DVD 3 is reproduced in this way, in the DVD player 1, a navigation command for controlling the reproduction of video data is reproduced by the signal processing circuit 9, and this navigation command is analyzed by the system control circuit 8. As a result, the DVD player 1 detects, for example, a scene in which the content provider prohibits fast-forwarding, a scene in which frame-forwarding is prohibited, and the like.

  In the DVD player 1, the operation of the operator in the remote commander 15 is selectively accepted by the system control circuit 8 based on the analysis result of the navigation command, thereby for example prohibiting fast-forwarding by the content provider. In the scene, the DVD 3 is reproduced without accepting the fast-forward operation by the user. Similarly, when the content provider prohibits frame advance, the DVD 3 is reproduced without accepting the frame advance operation by the user, and the content provider's intention is reproduced. Can be reflected.

  However, when the operation of the remote commander 15 is selectively received in this way, it is extremely inconvenient for users who are not used to it. As a result, in the DVD player 1, when the user operates the guide operation element 15 </ b> C provided in the remote commander 15, an operation element that can be operated is displayed on the monitor device 11 based on the analysis result of the navigation command. Thereby, in the DVD player 1, even a user who is not used to the user can confirm the operation elements related to the remote commander 15 that can be operated by this display, and the usability can be improved accordingly.
