  Hereinafter, a hard disk drive (HDD) integrated optical disk apparatus will be described as an example of a video / audio recording / reproducing apparatus. FIG. 1 is a block diagram showing the configuration of an HDD integrated optical disk device 10 and its peripheral devices. Connected to the HDD-integrated optical disk device 10 are a display device 11 such as a television and an external device 12 typified by a video / audio recording / reproducing device such as a set-top box or a video deck such as a cable television or satellite broadcast. . The HDD integrated optical disk device 10 can be operated by a remote controller 13. Hereinafter, a DVD will be described as an example of the optical disk.

  The HDD-integrated optical disc apparatus 10 includes an antenna 15 that receives a television broadcast signal, a tuner 16 that demodulates and digitizes the television broadcast signal received by the antenna 15, and MPEG-2 video and audio data received from the tuner 16 and the external device 12. And an audio / video compression / decompression unit 17 that performs compression / encoding in accordance with the above-mentioned standards, and decompresses / decodes compressed image data reproduced by the HDD recording / reproduction unit 18 or DVD recording / reproduction unit 19. The compressed video / audio data received from the video / audio compression / decompression unit 17 and the HDD recording / reproducing unit 18 for recording the compressed video / audio data received from the HDD to the HDD or reproducing the data recorded on the HDD A DVD recording / reproducing unit 19 for recording on the inserted DVD and for reproducing data recorded on the DVD; An OSD (On Screen Display) unit 20 that enables various setting values to be set while being displayed on a part of the display device 11, and an image output unit 21 that converts an image signal from the OSD unit 20 into an analog signal and outputs the analog signal to the display device 11. An audio output unit 22 that converts the audio signal from the image / audio compression / expansion unit 17 into an analog signal and outputs the analog signal to the display device; a memory 23 that includes a ROM or a RAM; and a remote control reception unit 24 that receives a signal from the remote controller 13; An external I / F 25 to which the external device 12 is connected and a control unit 26 that controls each part of the HDD integrated optical disk device 10 are provided.

  The memory 23 also stores a plurality of sound effects (such as sounds at startup, key operation sounds, and screen switching sounds). The sound output unit 22 also outputs sound effects stored in the memory 23 in accordance with each operation such as screen switching. The control unit 26 also performs control of a sound effect generation setting mode for generating sound effects and setting sound effects, and control during sound effect output. The sound effect generation setting mode will be described below.

  2 to 4 are flowcharts showing the operation of the HDD-integrated optical disc apparatus 10 in the sound effect generation setting mode. 2 and 3 are connected by A, and FIGS. 2 and 4 are connected by B.

  First, when the operation panel (not shown) of the remote controller 13 or the HDD integrated optical disc apparatus 10 is operated by the user and the sound effect generation setting mode is selected and determined, the control unit 26 activates the sound effect generation setting mode, and the step In S10, a menu screen for generating and setting sound effects is displayed on the display device 11. Items displayed on the menu screen include “generation of sound effects” and “setting of sound effects”.

  Proceeding from step S10 to step S11, it is determined which of the generation of the sound effect or the setting of the sound effect has been selected and determined. When the generation of the sound effect is selected and determined in step S11, the process proceeds to step S12 to display the sound effect generation menu screen on the display device 11. The sound effect generation menu displays a list of programs recorded on the HDD or DVD and prompts the user to select from which program the sound effect is to be generated. In addition to selecting a program, it may be possible to specify in detail the position from which playback is to be performed by hierarchically displaying a break in the program such as a chapter.

  Proceeding from step S12 to step S13, it is determined whether or not the user has selected and decided a desired program. When a program is selected and determined in step S13, the process proceeds to step S14 to reproduce the program. Note that at least the audio needs to be reproduced for the reproduction of the program, but it is more convenient to reproduce the video at the same time.

  Proceeding from step S14 to step S15, it is determined whether or not a start point for extracting the sound effect is instructed during reproduction of the program. When a user wants to use a sound effect during program playback, the user operates the remote controller 13 or the like to indicate the start point of the sound effect. When the start point is instructed in step S15, the process proceeds to step S16, and the position is temporarily stored in the memory 23 as the start point.

  Next, the process proceeds from step S16 to step S17, and it is determined whether or not an end point for cutting out the sound effect is instructed during the reproduction of the program. The user operates the remote controller 13 or the like to specify the end point in the same way as the start point. When an end point is instructed in step S17, the process proceeds to step S18, and the position is temporarily stored in the memory 23 as the end point.

  On the other hand, if the end point is not instructed in step S17, the process proceeds to step S19 to determine whether or not a predetermined time has elapsed from the start point. This predetermined time may be the longest time of the sound effect, and may be 5 seconds, for example. If the predetermined time has not elapsed in step S19, the process returns to step S17 again, and if the predetermined time has elapsed, the process proceeds to step S20. In step S20, the start point is canceled by deleting the temporarily stored start point. From step S20, the process returns to step S15 and waits for the start point instruction again.

  From step S18, the process proceeds to step S21 to end the reproduction, and the process proceeds to step S22 to cut out the sound from the start point to the end point based on the start point and end point temporarily stored in the memory 23. And it progresses to step S23 and the audio | voice cut out is memorize | stored in the memory 23 as sound effect data. The sound effect data may be distinguished by appropriately giving a name. This completes the sound effect generation process.

  In order to cut out the sound recorded on the recording medium, the recording medium is played back in step S14. However, if the sound recorded on the recording medium can be cut out arbitrarily, there is no need to play back.

  Next, the case where the sound effect setting is selected and determined in step S11 will be described. Proceeding from step S11 to step S30, a sound effect setting menu screen is displayed on the display device 11. The sound effect setting menu displays a list of actions serving as triggers for outputting sound effects, and prompts the user to select which action sound effect is to be changed.

  Proceeding from step S30 to step S31, it is determined whether or not the user has selected and decided a desired operation. When the operation is selected and determined in step S31, the process proceeds to step S32, where a list of sound effect data recorded in the memory 23 is displayed, prompting which sound effect data to set. When a plurality of sound effect data are stored, only sound effect data appropriate as the sound effect time for the selected operation may be selected.

  Proceeding from step S32 to step S33, it is determined whether or not the user has selected and determined desired sound effect data. When the desired sound effect data is selected and determined in step S33, the process proceeds to step S34 to set so as to associate the selected action with the sound effect data. This completes the sound effect setting process.

  Note that steps S30 and S31 are necessary in the case of a specification in which sound effects can be set for a plurality of operations, but are not necessary in the case of a specification in which the same sound effects are set for all the operations.

  The sound effect generated and set as described above is output through the sound output unit 22 by reading out sound effect data corresponding to the operation from the memory 23 at each operation.

  In this manner, by cutting out and using desired sound as a sound effect from a program recorded on a recording medium, it is possible to easily produce the sound effect while maintaining the sound quality. Therefore, it is possible to realize the HDD integrated optical disc apparatus 10 with high commercial value and improved sound effect customization.

  The present invention relates to a video / audio recording / reproducing apparatus such as a video cassette recorder or an optical disk apparatus such as a DVD, or a hard disk recorder, or a multi-function apparatus in which a plurality of video / audio recording / reproducing apparatuses are incorporated in one casing, for example, an optical disk apparatus integrated with a hard disk drive. Etc. can be used.
