  The present invention relates to an apparatus for reproducing video information, an image display apparatus and a projector including the apparatus, and a control method for the video information reproducing apparatus.

  Conventionally, with regard to a DVD video player, Patent Document 1 states that “When a DVD video disc is loaded into a player, many promotional videos are automatically reproduced, and it is painful to watch the same promotional video every time the same DVD is played. As a technology for the problem that the image of the company is also damaged for the disc manufacturing company, etc., “when the loaded disc is played for the first time on this player, the disc identification symbol from the DVD video data, User operation control information indicating whether the Stop operation and the FF operation can be performed, which is recorded in the data portion of the attached video that does not require automatic reproduction, such as a promotional video, is captured and recorded in the memory table 19 for each disk identification symbol. During playback from the first time onward, the operation is immediately performed from the data in the memory table on the disk that can be operated by the Stop operation. As a result, the player skips to the first part of the main video according to the player characteristics. When the stop operation is invalid and the FF operation is possible, the FF operation is performed until the title is changed. Proposed (summary).

JP 2001-291377 A

The technique described in Patent Document 1 is based on the premise that the same DVD is reproduced a plurality of times by a DVD video player.
However, in the case of a rental DVD, for example, if the DVD is viewed once, the DVD is often returned, and a storage capacity for user operation control information or the like is required for the single viewing. There is a problem from the viewpoint.

  The present invention has been made in order to solve the above-described problems, and can quickly end a playback portion that cannot be skipped without separately storing information stored in a video information storage medium. It is an object of the present invention to obtain a video information reproducing apparatus that can be used.

A video information reproducing apparatus according to the present invention includes a video information reproducing unit that reproduces video information stored in a video information storage medium, a video signal processing unit that processes a video signal reproduced by the video information reproducing unit, A storage unit that stores image data; a control unit that controls operations of the video information reproduction unit and the video signal processing unit; and an operation input unit that receives an operation input and outputs the operation signal to the control unit. The video information playback unit obtains whether or not skipping of a playback portion and fast-forwarding is possible, and the control unit obtains whether or not skipping and fast-forwarding obtained by the video information playback unit are possible, and skips from the operation input unit. When the operation signal indicating that the playback should be performed is received, if the playback position at that time is not skippable and can be fast-forwarded, the predetermined image data is read from the storage unit and the playback section is read. It instructs the video information playback unit to fast forward and to output the video signal of the contents of said predetermined image data in the image signal processing unit.
Therefore, when skipping is instructed for a video that cannot be skipped and that can be fast-forwarded, fast-forwarding can be executed and an operation similar to skipping can be performed in terms of the user's experience. As a result, even if skipping is set for a video that the user does not want to view, the video can be quickly terminated.

  In addition, when the above-mentioned fast-forwarding is performed, the content of the predetermined image data is displayed on the screen, so that the user can not see a rapidly changing screen during fast-forwarding and reduce the burden on the user. Can do.

Further, in the video information reproducing apparatus according to the present invention, the control unit receives an operation signal indicating that the skip should be performed from the operation input unit, and when the reproduction part is fast-forwarded, the fast-forwarding reproduction When the end of the part is detected, the video information reproducing unit is instructed to end fast-forwarding, and the video signal processing unit is instructed to stop outputting the video signal of the predetermined image data.
For this reason, as with the skip operation, the playback position can be skipped to the next playback location with a single operation input, so that the operation is substantially the same as skip, which is convenient for the user.

An image display device according to the present invention includes any one of the video information reproducing devices described above and an image display unit that displays an image based on the output video signal.
Therefore, similarly to the video information reproducing apparatus described above, it is possible to skip an image that the user does not want to see, and the same effect as that of the video information reproducing apparatus can be achieved.

In addition, a projector according to the present invention includes any one of the above-described video information reproducing apparatuses and a projection unit that projects video based on the output video signal.
Therefore, similarly to the video information reproducing apparatus described above, it is possible to skip an image that the user does not want to see, and the same effect as that of the video information reproducing apparatus can be achieved.

A video information playback apparatus control method according to the present invention includes a storage means for storing predetermined image data, and an operation input means for receiving an operation input and outputting an operation signal. A method for controlling a video playback operation, comprising the step of acquiring whether or not video playback can be skipped and fast-forwarded, and when receiving an operation signal to be skipped from the operation input means, When the playback location cannot be skipped and can be fast-forwarded, the predetermined image data is read from the storage means, the playback location is fast-forwarded, and a video signal having the content of the predetermined image data is output.
For this reason, when skipping is instructed for a video that cannot be skipped and that can be fast-forwarded, the video playback operation of the video information playback device is controlled so that fast-forwarding is performed and an operation similar to skipping is performed by the user be able to.
As a result, even if skipping is set for a video that the user does not want to view, the video can be quickly terminated.

Embodiment 1 FIG.
FIG. 1 is a functional block diagram of a video information reproducing apparatus 10 according to Embodiment 1 of the present invention.
The video information reproducing apparatus 10 is an apparatus for reproducing a DVD. The video information playback apparatus 10 outputs the video to be played back to the display 20, and the user views the playback video on the display 20.
The video information playback apparatus 10 includes an operation panel 11, an operation signal processing unit 12, a DVD playback unit 13, a video signal processing unit 14, a control unit 15, and a storage unit 16.

The operation panel 11 is provided on the outer surface of the main body housing of the video information reproducing apparatus 10 and receives user operation information.
When the user presses a key disposed on the operation panel 11, an operation signal corresponding to the key is output to the operation signal processing unit 12.
The operation signal processing unit 12 receives the operation signal output from the operation panel 11, performs processing such as conversion into a digital signal, and outputs the processed signal to the control unit 15.
The “operation input unit” in the claims corresponds to the operation panel 11 and the operation signal processing unit 12.

The DVD playback unit 13 appropriately includes a tray for setting a DVD, an optical head, and the like, reads video information stored in the DVD, and plays it back as a video signal. The reproduced video signal is output to the video signal processing unit 14.
The “video information reproducing unit” in the claims corresponds to the DVD reproducing unit 13.
The “video information storage medium” corresponds to a DVD.

The video signal processing unit 14 generates a digital output video signal based on the video signal received from the DVD playback unit 13 and an instruction from the control unit 15 and outputs the digital output video signal to the display 20.
The video signal processing unit 14 is configured by a microprocessor or the like, and performs the above processing by executing a built-in program.
The video signal processing unit 14 and the display 20 are connected by an appropriate video signal cable or the like.

The control unit 15 controls the operations of the DVD playback unit 13 and the video signal processing unit 14.
Also, after reading image data, which will be described later, stored in the storage unit 16 and when the playback portion of the DVD cannot be skipped, each unit is instructed to perform a fast forward operation and image data display as described later.
The control unit 15 can be configured by hardware such as a circuit device that realizes the function, or can be configured by an arithmetic device such as a microcomputer or a CPU and a control program that defines the operation thereof.

The storage unit 16 stores image data to be described later. The format of the image data may be arbitrary as long as the control unit 15 can interpret it. For example, a standard image format such as JPEG or BMP is convenient for processing.
The storage unit 16 can be configured by a storage device such as an HDD (Hard Disk Drive) or a flash ROM.

The function blocks in FIG. 1 have been described above.
Next, as a background of the present invention, a case where it is desired to skip (or stop) playback of a DVD will be described.

For example, in the case of a rental DVD, a trailer or an advertisement video may be inserted before the main part is reproduced. These videos may be set so that they cannot be skipped or stopped so as to be surely viewed by the user.
In this case, the user is forced to view these videos, and these videos may take, for example, more than 10 minutes depending on the DVD.

If the user does not want to see these videos, the user skips or fast forwards.
When skipping, it is convenient because the user can skip the playback position to the next playback location (for example, the next TITLE or CHAPTER) by simply pressing the skip key once. It is set so that it cannot be skipped.
Therefore, the user tries to fast-forward these videos and quickly watch the main video.

However, in the case of fast-forwarding, unlike fast skipping, video fast-forwarding continues unless fast-forwarding is canceled, so you must watch the fast-forwarded playback screen to cancel fast-forwarding when playback of the main part starts. It was inconvenient for the user.
In addition, since the video on the fast-playing screen changes rapidly, it places a burden on the user's eyes.

On the other hand, in the technique described in Patent Document 1, information stored in a DVD is temporarily stored in a DVD video player when the DVD is played for the first time, and the information is used for the second and subsequent playbacks. It is to reach the video of early.
However, such a method cannot be used in the case of a DVD that is often returned after viewing once, such as a rental DVD. In addition, since a storage area for storing information stored in the DVD is required in the DVD video player (or peripheral device), a certain cost occurs.

Therefore, in the first embodiment, a video for which skipping is prohibited is quickly ended without providing a storage area for storing information stored in the DVD in the video information reproducing apparatus 10 (or peripheral device). Suggest a method.
Further, in the first embodiment, the burden on the user's eyes is reduced by the fast-forward playback screen.

The case where it is desired to skip DVD playback has been described above.
Next, a specific procedure for quickly reaching the main video will be described.

  FIG. 2 is an example showing a transition of screen display when a video such as a trailer or an advertisement is finished early to reach the main video. Hereinafter, each step of FIG. 2 will be described.

(A) At the time of DVD insertion The user sets a DVD in the DVD playback unit 13 of the video information playback apparatus 10.
At the beginning of the DVD, videos such as trailers and advertisements are inserted, and these videos are reproduced.
(B) Pressing the skip key The user presses the skip key provided on the operation panel 11 in order to quickly view the main video. However, images such as trailers and advertisements are set so that they cannot be skipped.

(C1) Screen display during fast-forwarding The video information reproducing apparatus 10 fast-forwards these videos at the fastest speed instead of skipping videos such as trailers and advertisements. At this time, an image prompting the user to wait is displayed on the screen, so that the user does not see a rapidly changing screen during fast-forwarding.
(C2) Processing in Background The video information playback apparatus 10 fast-forwards the DVD at the fastest speed on the back side where an image prompting standby is displayed.

(D) End of fast-forwarding When the video information playback apparatus 10 detects the end of a video such as a trailer or an advertisement, the video information playback apparatus 10 erases the displayed image prompting standby and returns to the normal DVD playback operation. Thereafter, the main video is reproduced.

The screen transition when the main video is quickly reached has been described with reference to FIG.
Next, an internal process when the video information reproducing apparatus 10 performs the operation of FIG. 2 will be described.

  FIG. 3 is a processing flow when the video information reproducing apparatus 10 receives a skip operation input from the operation panel. Hereinafter, each step will be described.

(S301)
The user presses a skip key provided on the operation panel 11.
An operation signal indicating that skipping should be performed is output to the control unit 15 via the operation panel 11 and the operation signal processing unit 12. The control unit 15 receives the signal and starts this processing flow.
(S302)
The DVD playback unit 13 acquires UOP (user operation control) information of the current playback location. The acquisition timing may be when the reproduction of the DVD is started or when the control unit 15 is instructed.
The control unit 15 receives the UOP information acquired by the DVD playback unit 13.

(S303)
The control unit 15 determines whether or not the current playback location can be skipped based on the UOP information acquired in step S302.
If skipping is possible, the process proceeds to step S310, and if skipping is not possible, the process proceeds to S304.
(S304)
Based on the UOP information acquired in step S302, the control unit 15 determines whether the current playback location can be fast-forwarded.
If fast-forwarding is possible, the process proceeds to step S305, and if fast-forwarding is not possible, the process proceeds to S311.

(S305)
The control unit 15 reads the image data stored in the storage unit 16.
Next, the control unit 15 delivers the content of the read image data to the video signal processing unit 14 and instructs to output the video signal of the content of the image. The image referred to here is an image prompting the user to wait as shown in (c1) of FIG.
The video signal processing unit 14 outputs a video signal having the content of the received image data. The display 20 displays the image on the screen.
(S306)
The control unit 15 instructs the DVD playback unit 13 to fast-forward the DVD at the highest speed.
The DVD playback unit 13 fast-forwards the DVD at the highest speed.
During this time, the content of the image data is displayed on the display 20.

(S307)
The control unit 15 determines whether or not the current playback location has ended.
Here, “determination of whether or not the playback point has ended” means whether or not fast-forward playback has reached the playback point to which it was skipped if it was skipped at the current playback point. It is.
As a determination method, for example, the end of the playback position may be received from the DVD playback unit 13, or a pointer to the end position of the playback position is acquired in advance, and the fast-forward position reaches that pointer. The fast-forwarding may be terminated at. In addition, other methods may be used.
If it is not detected that the current playback portion has ended, this step is continued. If it is detected that the playback portion has ended, the process proceeds to step S308.

(S308)
The control unit 15 instructs the video signal processing unit 14 to stop outputting the video signal having the content of the image data.
The video signal processing unit 14 returns to the normal video playback state and outputs a video signal to be played back by the DVD playback unit 13.
(S309)
The DVD playback unit 13 ends the fast-forward operation and plays back the next playback location. Thereafter, the normal DVD playback operation is performed.

(S310)
The control unit 15 instructs the DVD playback unit 13 to skip the current playback location.
The DVD playback unit 13 skips the current playback location.
(S311)
The control unit 15 instructs the video signal processing unit 14 to output a video signal representing a message indicating that skipping is not possible. The video signal processing unit 14 outputs a video signal to that effect.

The processing flow when accepting the skip operation input has been described above.
The “reproduction location” corresponds to the following (1) to (2), for example.

(1) The trailer or advertisement video may be independent of the main video and may constitute one “TITLE” on the DVD-VIDEO standard. In this case, the “reproduction portion” corresponds to one “TITLE”.

(2) In addition to “TITLE”, video blocks such as “CHAPTER” may be configured. In this case, the “reproduction location” corresponds to one “CHAPTER”.
However, in practice, “CHAPTER” is rarely set to be non-skipable.

  That is, the “reproduction portion” in the first embodiment is, in other words, a video unit in which reproduction is skipped when skipping is executed. Specifically, it differs depending on the specification of the DVD to be reproduced and the configuration of the video block, as exemplified in the above (1) and (2).

As described above, the video information playback apparatus 10 according to the first embodiment receives an operation input indicating that skipping should be performed, and if the playback location at that time is not skippable and can be fast-forwarded, the playback location is displayed. Fast forward at the highest speed.
As a result, when the user instructs skipping at a playback position that is set so as not to be skipped, the fastest fast-forward is performed instead of skipping, so that an operation similar to skipping can be performed.
In particular, it is convenient for the user when a video that the user wants to finish early cannot be skipped, such as a trailer or an advertisement video.

  Further, the video information reproducing apparatus 10 according to the first embodiment operates so as to display the image stored in the storage unit 16 during the above-described fastest fast-forwarding. It is possible to reduce the burden on the user when he / she is.

Further, when the video information reproducing apparatus 10 according to the first embodiment detects that the above-mentioned fast-forwarding playback portion has ended, the video information reproducing device 10 ends the fast-forwarding and stops displaying images to perform normal DVD playback operation. Return to.
Therefore, the playback position can be skipped to the next playback location by performing only one operation input, and the operation is substantially the same as the skip operation.
Therefore, the operation is almost the same as that of skipping a playback portion that the user does not want to see, which is convenient for the user.

Embodiment 2. FIG.
In the first embodiment, when the user presses the skip key, a configuration and an operation example are described in which it is determined whether or not the playback position at that time can be skipped, and fast-forwarding is performed.
In the second embodiment of the present invention, a configuration example different from that of the first embodiment regarding the key will be described.

In the second embodiment, a second skip key is newly provided on the operation panel 11.
The second skip key is a key that operates only when the playback portion cannot be skipped and fast-forwarding is possible. The operation when the second skip key is pressed is the same as the skip key in the first embodiment.
Further, the present invention is not limited to newly providing the second skip key, and an equivalent function may be realized with other existing keys.

Whichever key configuration realizes the function of the first embodiment, when the key is pressed, the video information reproducing apparatus 10 receives an operation signal indicating that “skip” should be performed, and the processing described in FIG. Run the flow.
In addition, when the normal skip key is pressed, an operation signal indicating that “skip” should be performed, and when a newly configured key is pressed, “skip if skip is possible, fast forward if not possible” A specific content of “skip” may be distinguished in detail by a key, such as an operation signal to that effect.
What kind of operation signal is configured may be appropriately designed.

  In the above description, an example in which each key is provided on the operation panel 11 of the video information reproducing apparatus 10 has been described.

As described above, according to the second embodiment, the same effect as in the first embodiment can be exhibited.
Further, since the second skip key is provided separately from the skip key, the normal skip operation and the skip operation according to the present invention can be explicitly distinguished.

Embodiment 3 FIG.
In Embodiments 1 and 2 described above, the video information playback apparatus 10 has been described as playing back a DVD. However, the application target of the present invention is not limited to the one that reproduces a DVD, and can be applied to an apparatus that reproduces video information stored in an arbitrary video information storage medium.
Also, the type of video information is not limited to the DVD and its corresponding format, and the present invention can be applied to a video information playback device that plays back any type of video information.

Further, in the first embodiment, whether to skip the playback portion or whether to fast-forward is acquired from the UOP information. However, if a video information storage medium other than a DVD is used, necessary information is appropriately acquired according to the format. do it.
If there is no information corresponding to the UOP information, whether or not skipping or fast-forwarding is not a problem, and a normal reproduction operation may be performed. That is, since it is not set so that skipping and fast-forwarding cannot be performed, a normal playback operation is sufficient.

Similarly, when a video information storage medium other than a DVD is used, the “playback location” is not necessarily a video block such as “TITLE” or “CHAPTER”. May be handled as a “reproduction location” to be fast-forwarded.
That is, a video unit that is skipped when skipping may be handled as a “playback location”.
