Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video reproducing apparatus having a selective reproducing function for selecting and reproducing specific information in a recording medium, and particularly, it is possible to collectively reproduce unselected information as a digest. The present invention relates to a video playback device.

[0002]

2. Description of the Related Art Various video reproducing devices have been developed, but in recent years, devices having various functions have been developed and commercialized. For example, as a new function by a DVD device (digital video display), there is one called a parental level function. For example, if there is a scene in the optical disc that the parent does not want to show to the child, if this parental level function is selected, that scene will be cut (deleted) at the time of playback and it will be as if it were a continuous video. Can be replayed. In addition, a multi-angle function that allows the user to select the viewpoint of the image, such as playing the face of the actress mainly in a certain scene during movie playback or playing the entire view in a certain location, depending on the user's selection There is. The case of the parental level function will be described below. However, the multi-angle function can be processed in the same manner, and the description thereof will be omitted.

FIG. 5 is a block diagram for explaining a parental level function of a conventional video reproducing apparatus (DVD apparatus).
Hereinafter, description will be made with reference to the drawings. Reference numeral 1 denotes an optical disc on which digitized image information and the like are recorded. Information for specifying a parental level (cutting a specific scene when the image information recorded on the disc is normally reproduced) is included in the optical disc 1. (Start address and data length or start address and end address) are recorded.

Reference numeral 3 denotes a video reproducing device having a parental level function for reproducing the optical disc 1.
The pickup 21 which irradiates a laser beam on the above and receives the reflected light to read the image / sound information recorded in a bit state, outputs the image / sound information read by the pickup 21 to the signal processor 24, and , The start address and data length (or start address and end address) of a specific scene to be cut at the time of normal reproduction are read from the information regarding reproduction recorded on the optical disc 1, and which part is cut and reproduced at the time of reproduction. Various instructions to the control unit 32 for instructing whether or not, the signal processing unit 24 for reproducing the video / audio signals, the liquid crystal for displaying the reproduced image, the display 25 such as a CRT, the speaker 26 for reproducing the sound, and the control unit 32. The switch 37 is provided.

Next, the operation will be described. The information on the optical disc 1 mounted on the video reproducing device 3 is read by the pickup 21. The information (e.g., scene) is sent to the signal processing unit 24 via the control unit 32, where various signal processing is performed, separated into a video signal and an audio signal, and reproduced by the display 25 and the speaker 26. On the other hand, the pickup 21 reads the recorded specific scene start address and specific scene end address (there may be a plurality) in the optical disc 1. When the pickup 21 comes to the corresponding address, the pickup 21 jumps to It is skipped and played. In this way, the inconvenient scene is deleted and reproduced.

[0006]

In the above method, the inconvenient scenes among the scenes recorded on the optical disc are deleted and reproduced, which is convenient when a large number of unspecified persons are targeted. However, if it is desired to view a scene deleted later only for a specific person, the optical disc needs to be reproduced from the beginning, which takes time. That is, it is not possible to see a digest that summarizes only the deleted parts in a short time.

It is an object of the present invention to provide a video reproducing apparatus capable of reproducing a part of video information recorded on a recording medium by deleting it and reproducing only the deleted information.

[0008]

In order to achieve the above object, the present invention provides a reproducing means for reading and reproducing information recorded in a recording medium, and a recording medium in the recording medium based on information concerning reproduction of the recording medium. In the video reproducing apparatus having a selective reproducing means for selecting and reproducing the specific information of the above, the selective reproducing means is provided with a storage means for storing information regarding reproduction of unreproduced information not reproduced at the time of reproducing the recording medium. The present invention is characterized by further comprising digest reproducing means for selectively reproducing the unreproduced information in the recording medium based on information regarding reproduction of the unreproduced information stored in the storage means.

The digest reproducing means is also characterized in that the digest reproducing means also reproduces information in a predetermined range before and after the unreproduced information. Further, the recording medium is characterized by further comprising erasing means for erasing information relating to reproduction of the unreproduced information stored in the storage means when the recording medium is ejected from the video reproducing device.

The information regarding the reproduction of the unreproduced information is characterized in that a start position and an end position of the unreproduced information are designated. The information regarding the reproduction of the unreproduced information is characterized in that a start position and a data length of the unreproduced information are designated.

[0011]

In the present embodiment, the processing of the video reproducing apparatus having the parental level function will be described. However, since the same processing is performed in the case of the video reproducing apparatus having the multi-angle function, the description thereof will be omitted. Further, general processing of the video playback device (for example, communication management, deck management, display, etc.) is also the same as that of the conventional video playback device, and therefore description thereof is omitted.

FIG. 1 is a diagram for explaining the configuration of a video reproducing apparatus according to an embodiment of the present invention. Hereinafter, description will be made with reference to the drawings. Reference numeral 1 denotes an optical disc on which digitized image information or the like is recorded. Information (designated to cut a specific scene when reproducing image information recorded on the disc) is specified in the optical disc 1 ( The start address and data length or the start address and end address, etc.) are recorded. In the multi-angle function, the type of information recorded on the disc and the data are different, and the detection process is slightly different (the data to be compared is different), but the process itself is essentially unchanged.

Reference numeral 2 is a video reproducing apparatus having a parental level function for reproducing the optical disc 1.
The pickup 21 which irradiates a laser beam on the above and receives the reflected light to read the image / sound information recorded in a bit state, outputs the image / sound information read by the pickup 21 to the signal processor 24, and , A start address and a data length (or a start address and an end address) of a specific scene to be cut at the time of the normal reproduction are read from the information about the reproduction recorded on the optical disc 1 and stored in the memory 23. A control unit 22 for instructing whether to cut and play back, and controlling digest playback with only the cut specific scene as a digest, a memory 23 for storing a cut start address and a data length determined by the control unit 22, an image .Signal processing unit (microcomputer) 24 that performs playback processing of audio signals, liquid crystal that displays playback images Display 25 such as a CRT, and a switch 27 which gives various instructions to the speaker 26 and the control unit 22 reproduces the voice.

FIG. 2 is a flow chart for explaining the function management processing by the video reproducing apparatus according to the embodiment of the present invention. Hereinafter, description will be given according to the flowchart. In step S1, it is determined whether or not the parental level function is on. If it is on, the process proceeds to step S2, and if it is off, the process ends. That is, it is determined whether or not the user has instructed the parental level function with the switch 27 in the normal reproduction.

In step S2, parental level function mode processing is executed. Since this processing is described in detail in the normal reproduction processing (step S11 to step S16) in FIG. 3, the description thereof is omitted here. In step S3, it is determined whether the disc is stopped or ejected. If it is stopped or ejected, the process proceeds to step S4, and if it is not stopped or ejected, the process returns to step S2. That is, it is for determining whether or not the normal reproduction in the parental level function mode is continued, and when the switch is operated so as to stop or eject the optical disk 1 from the video reproducing apparatus 2, the normal reproduction ends. I judge that I did.

In step S4, the parental level function mode is released and the process proceeds to step S5. That is, the parental level function is set every time normal reproduction is performed, and is set to the initial state (normal state of the parental level function) after the normal reproduction is completed. In step S5, the disc is stopped and ejected, and the process is completed. Since this process is exactly the same as the process of a normal video reproducing apparatus, its description is omitted.

FIG. 3 shows the normal reproduction (parental level function mode processing) by the video reproducing apparatus according to the embodiment of the present invention.
6 is a flowchart for explaining a process performed by the control unit. Hereinafter, description will be given according to the flowchart. In the following description, the non-select scene means a scene that was cut by the parental level function during normal reproduction and was not reproduced.

In step S11, it is determined whether or not the normal reproduction is being performed. If the normal reproduction is being performed, the process proceeds to step S12, and if the normal reproduction is not being performed, the process ends. This is a non-select scene digest (a digest that collects only the scenes that were cut by the parental level function during normal playback and was not played, and is simply called the digest below) must be created in parallel with normal playback. Therefore, this determination can be made based on whether or not the optical disc 1 is attached to the video reproducing device 2 and the switch 27 or the like is instructed to perform normal reproduction.

In step S12, it is judged whether or not the digest is selected, and if it is selected, the step S1
The process moves to 3 and ends the process if not selected. In other words, since the parental level function operates during normal playback and a part of the image information is cut, after the normal playback ends, it is possible to determine whether or not a digest that collects only the cut parts is necessary. is there. The determination as to whether it is necessary or not is previously instructed by the user using the switch 27 or the like.

In step S13, it is determined whether or not the optical disc 1 is ejected from the video reproducing apparatus 2. If ejected, the process proceeds to step S15. If not ejected, the process proceeds to step S14. This is to serve as a reference for determining whether or not the digest is continuously reproduced after the normal reproduction is completed with a part of the scene cut by the parental level function. In other words, when the digest reproduction is performed, the optical disc 1 is continuously ejected from the video reproducing device 2 and is continuously ejected. When the digest reproduction is not performed, the optical disc 1 is ejected from the video reproducing device 2 as described above. do.

In step S14, it is determined whether or not the scene is a non-select scene, and if it is a non-select scene, the procedure moves to step S16. If it is not a non-select scene, the procedure returns to step S11. Whether or not the non-selected scene portion is reached during normal playback is recorded in advance in the optical disc 1 as the address (start address, data length or end address) of the non-selected scene as information regarding playback. Judge based on

In step S15, the memory 23 storing the start address of the non-selected scene is cleared and the process is terminated. That is, the optical disc 1 is the video playback device 2
After being further discharged, the digest is considered not to be reproduced and is deleted from the memory 23 so that the start address of the non-selected scene is not stored. This process is performed in order to prevent the created digest from being reproduced later by another person.

In step S16, the address (start address, data length or end address) of the non-selected scene is stored in the memory 23, and the process proceeds to step S17. That is, the address stored in the memory 23 is used as information regarding reproduction during digest reproduction. Also,
If there are a plurality of non-selected scenes during normal reproduction, the processing from step S11 to step S17 (step S1
(Except 5) is repeated to store the addresses of all non-selected scenes in the memory 23.

In step S17, the pickup is jumped to the end address of the non-selected scene and the process returns to step S11. That is, it is troublesome to play the non-selected scene during the normal playback, so the pickup is skipped to the end address so as not to be played. In this flowchart, step S12 is omitted (always Y
Is the same as the selected state). In that case, if even the start address of the non-selected scene is recorded on the optical disc 1 side as information regarding reproduction,
Since all non-selected scenes are automatically created as a digest, the operation of the switch 27 by the viewer can be reduced.

Further, in step S16, it is possible to add a margin to the start address and data length (or start address and end address) of the non-selected scene and store it in the memory 23. In this case, a little before and after the non-select scene (predetermined data length)
Since the digest can be played back together, there is an advantage that the story can be easily understood when playing back the digest.

FIG. 4 is a flow chart for explaining the processing performed by the control unit at the time of digest reproduction by the video reproducing apparatus according to the embodiment of the present invention. Hereinafter, description will be given according to the flowchart. In the following description, digest reproduction means reproduction of a digest that collects non-selected scenes that were not reproduced due to being cut by the parental level function during normal reproduction.

In step S21, it is judged whether or not the normal reproduction is completed, and if the normal reproduction is completed, step S21 is performed.
22. If not completed, the process ends. That is, in order to perform the digest reproduction, the normal reproduction of the optical disc 1 is performed in advance by using the parental level function,
Since it is necessary to create information regarding digest reproduction, it is determined whether or not information regarding digest reproduction has been created depending on whether or not normal reproduction has ended.

In step S22, switch processing is performed.
That is, the video playback device 2 is instructed to operate in response to the user's switch operation. In step S23, it is determined whether or not the digest reproduction is being performed. If the digest reproduction is performed, the process proceeds to step S24, and if it is not the digest reproduction, the process is ended. This determination is made based on whether or not the switch 27 is operated in step S22.

In step S24, the start address is read from the memory 23 and the process proceeds to step S25. That is,
At the time of normal reproduction, the parental level function is operated to read out the start address of the non-selected scene stored in the memory 23. In step S25, it is determined whether there is a remaining address, and if there is a remaining address, step S25.
If not, the process ends. This is to cope with the case where there are a plurality of non-selected scenes, and the processing is continued until it is confirmed that all the non-selected scenes have been reproduced. That is, the processing from step S23 to step S28 is repeated for the reproduction of one non-selected scene, and when there is no unread non-selected scene address in the memory 23, it is determined that the digest reproduction has ended (N in step S25). Then, the processing is completed.

In step S26, a jump process is performed and the process proceeds to step S27. That is, the pickup is moved (jumped) to the start address of the non-selected scene read from the memory 23. In step S27, digest reproduction processing is performed and then the process proceeds to step S28. That is, for one non-selected scene, the digest is reproduced by starting the reproduction from the start address.

In step S28, it is determined whether or not the non-selected scene is finished, and if it is finished, step S2
Return to step 3, and if not completed, return to step S27.
That is, it is determined whether or not the reproduction of one non-selected scene is completed, and it is determined based on the data length or the type of data (for example, end position data). Then, the reproduction process is continued in step S27 until one non-selected scene ends. When the reproduction of one non-selected scene is completed (Y in step S18), the process returns to step S23 to reproduce the next non-selected scene.

In addition, instead of determining whether or not the normal reproduction is ended in step S21, the normal reproduction is ended or interrupted (corresponding to a pause, and when restarted after the interruption, the reproduction is restarted from the interrupted position. It may be judged whether or not it has been continued. In the case of interruption, if the parental level function is activated to interrupt the playback during normal playback,
The parental level function is canceled in step S4 of the flowchart of FIG. 6 and all information thereafter is reproduced without being cut. Moreover, as long as the optical disc 1 is not ejected from the video playback device 2, the non-selected scene of the portion normally played back by operating the parental level function until it is interrupted is still stored in the memory 23 and is not cleared. It is also possible to play the non-selected scene as a digest after the end.

As described above, in this embodiment, after the video information recorded on the recording medium is reproduced by using the parental level function, only the non-selected scene cut by the parental level function can be reproduced as a digest. A video playback device can be provided.
