Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reproduction information editing apparatus and method for selectively reproducing a desired information section from video or audio continuous information recorded on a disk or another recording medium.

[0002]

2. Description of the Related Art Currently, video or audio is digitized and recorded, and the recorded information is arbitrarily edited by a user.
There are devices that can create their own video or audio programs. In addition, without changing the recorded information itself, information such as video already recorded on a recording medium such as a disk, tape, or semiconductor memory is selected, and the target (title, information section, etc.) is selected, and the selected information is selected. Program reproduction in which reproduction is performed in an arbitrary order is also possible.

An example of such a device is a DVD recording / reproducing device. In the DVD-VR (Video Recording) standard adopted in this DVD recording / reproducing apparatus, a playlist creating function is prepared for editing by the user. This allows the user to easily play back the title of each list edited by the user by selecting an arbitrary portion from the original title of the video or audio and saving the selected multiple playback portions as a list. It is for This play list can be recorded in the management information area of the DVD in which the original title to be edited is recorded.

Further, in order to edit the video or audio information, it is possible to mark an arbitrary section of the information and mark the section so that only the section can be taken out. This is realized by setting address information of the delimiter position and information indicating the delimiter, and linking and storing (or recording) the information with the target video or audio information. Such delimiter information is called an entry point and is used when recording digital video or audio information. Regarding the use of such entry point information, for example, Japanese Patent Application No. 2000-177131 (Japanese Patent Laid-Open No. 2001-35251).
No. 9, applicant: Hitachi, Ltd.).

[0005]

As described above, in the recording / reproducing apparatus which can be edited by the user, it is possible to reproduce a desired portion in an arbitrary order by using the playlist, but it is selected. It was not possible to edit such that a special effect was automatically added when playing a part. That is, it is impossible to pre-designate the reproduction mode, such as fast-forwarding reproduction of the selected portion, or reproduction with the voice erased. Therefore, in order to play back the original program with such special effects, the user can operate the device during playback or play the desired part from the original title once and add the special effects to it. Then, it was necessary to record again on the recording medium (the same recording medium as the original title or a different recording medium) and reproduce it by using recording information different from the original title. Therefore, there is a problem that editing work is troublesome for the user and the information recording area of the recording medium is wasted. Incidentally, the above-mentioned JP 2001-35
In the technology disclosed in No. 2519, it is possible to mark the information part to which a special effect is added by using an entry point, but the type of special effect can be specified along with this, and it can be automatically added during playback. To execute

Then, the reproduction information editing device in the present embodiment records the following information in the primary text information (PRM_TXTI) by editing using the type B entry point information (EPI). It should be noted that the registration of the entry point is automatically performed when recording the information (for example, during recording of the TV broadcast) or during reproduction, when the user instructs the entry point registration at a desired position (scene) by a key operation of a remote controller or the like. Be registered with. Conventionally used technology can be applied to the registration of this entry point.

Next, a specific example of the information recorded as the primary text information will be described with reference to FIG. Here, a code is assigned to the primary text information (PRM_TXTI) of the entry point information (EPI), to which an area for recording 5 types (5 categories) of reproduction mode information is assigned, and the following special reproduction is designated as each reproduction mode information. Describe.

<Playback Method> This is for instructing a mode related to the playback speed. For example, normal playback (default), fast forward playback, fast reverse playback, forward slow playback, backward slow playback, variable speed playback, etc. are defined. Then, the mode selected by the user from these is recorded.

<Playback video processing> This is a mode relating to the processing of video information to be played back, and normal display (default), negative display, mosaic display, sepia, fade-in, fade-out, zoom-in, zoom-out, etc. are defined in advance. The mode selected by the user is recorded.

<Playback audio processing> This is a mode relating to the processing of audio information to be played back, and normal playback (default), silence, echo, additional audio playback, etc. are defined, and the mode selected by the user from these is recorded. To do.

<Processing Time> The processing time is used to specify the time during which the above-described reproduction method, reproduction video processing and reproduction audio processing are executed in the information section specified by the entry point, and the specified time is recorded. . Note that the default is no designation (that is, designation of the entire information section).

<Pseudo Multi-story> This is for recording an identifier for selecting whether or not to reproduce the information section designated by the entry point. When the user creates a plurality of stories in a pseudo manner, It indicates which story the information section corresponds to.
For example, when two stories A and B are created, the story A is placed in the information section specified by the entry point.
Alternatively, one of the story B identifiers is recorded. When the user selects the story A according to the story selection menu at the start of reproduction, the information section or the identifier in which the identifier of the story A is recorded is recorded without reproducing the information section in which the identifier of the story B is recorded. Only the information section that has not been reproduced is reproduced. This is information for editing a so-called pseudo multi-story.

Next, the processing for additionally recording the above reproduction mode information to the primary text information of the entry point information (EPI) will be described with reference to FIG.

First, the user selects the reproduction mode while looking at the display screen of the title list of FIG. 7 (A). This screen display is performed by outputting the menu screen image of FIG. 7A from the control unit 30 of FIG. 1 to the video mixing unit 21.
It is displayed on the monitor 28. On this menu screen, from the title list display, that is, from the small screens 41 to 44 displaying the representative image or title number of each title,
The user operates the remote controller or the key input unit 35 to specify the title to be subjected to the special processing (select the title of the small screen 42 in the figure). When the number of titles is large, the display of the small screen is scrolled by designating the direction display 45 or 46. Next, with respect to the selected title, a desired process is designated by a cursor or the like from a reproduction method selection column 47, a reproduction video processing selection column 48, a reproduction audio processing selection column 49, and a processing time selection column 50. In the column, various modes described above can be selected by a predetermined key operation (for example, repeated operation of the selection key). Further, when the user wants to correct the selected mode, the "reset" display portion 51 is designated, and when the selection of all desired selection fields is completed, the "decision" display portion 52 is designated. "OK" display section 52 is specified

Next, the operation of setting the reproduction mode for each entry point will be described with reference to the chapter list display screen shown in FIG. 7B. Here, a chapter is a unit in which title information is subdivided, and when an entry point is designated by the user, an information section delimited by the entry point is formed as one chapter.

Also in the case of the operation from this chapter list display screen, as in the case of the title list display, the user can select a special image from each small screen 61-64 displaying the representative image of each chapter or the chapter number and the start time information. The chapter to be processed is designated (in the figure, the chapter on the small screen 63 is selected). When the number of chapters is large, the direction display 65 or 66 is designated to scroll the display on the small screen. Next, for the selected chapter, a reproduction method selection field 67, a reproduction video processing selection field 68, a reproduction audio processing selection field 69, a processing time selection field 70, and a pseudo multi-story selection field on the chapter list display screen. A desired process can be designated with a cursor or the like from 71, and various modes described above can be selected by a predetermined key operation in the designated field. Further, when the user wants to correct the selected mode, the "reset" display portion 72 is designated, and when the selection of all desired selection fields is completed, the "determination" display portion 73 is designated. When the "OK" display section 73 is designated, the other edit menu is displayed, and the "End" display section 5 is displayed.
When 3 is specified, the editing work is ended.

When the identifier is set in the pseudo multi-story selection field 71, the information indicating the multi-story is recorded in the management information of the title including the chapter, and the story selection menu is displayed during reproduction. Display and prompt the user to select a story.

Next, the operation of performing an editing operation using the above-described editing menu will be described with reference to FIGS. 8 and 9. FIG. 8 shows an operation flow of the editing operation on the title list display screen, and FIG. 9 shows an operation flow of the editing operation on the chapter list display screen.

In the flowchart of FIG. 8, the user operates the remote controller or the key input unit 35 to display the title list displayed on the monitor 28, thereby receiving the designation of the title for setting the reproduction mode (S1).
1). Next, for the selected title, any one of the mode designations of reproduction method selection (S12), reproduction video processing selection (S13), reproduction audio processing selection (S14), and processing time selection (S15) is received. The control unit 30 writes a code corresponding to the designated reproduction mode in the work RAM 33. When the processing time is selected, the processor 31 determines whether or not the time designated by the user is an appropriate value (S16).
The default value is restored (S17).

When the user specifies "reset" in the middle of specifying the reproduction mode (S18), the reproduction mode specified so far is returned to the default (S19), that is, the contents written in the work RAM 33 are corrected and the title is specified. The process returns to the process (S11). When the user has designated "decide" or "end" (S20), each reproduction mode information (code) stored in the work RAM 33 is stored in the primary text information area of all entry point information (EPI) belonging to the designated title. Is added. Then, the entry point information is supplied to the data processing unit 15 and recorded in the management information recording area of the DVD-RAM disk 11 or the hard disk 12 (S21).

The entry point information is also stored in another memory (for example, FRAM) of the control unit 30, and D
Unless the VD-RAM disk is replaced or the entry point information is updated, the playback operation can be controlled using the entry point information stored in the memory without reading the entry point information from the disk.

When the user specifies "end" (S
22), returning the screen display of the monitor 28 to the normal display,
End the editing operation.

Next, the operation of setting the reproduction mode from the chapter list display will be described with reference to FIG. However, the operation is almost the same as the case of displaying the title list. In other words, the chapter that sets the playback mode is specified (S
31), for the next selected chapter, a reproduction method selection (S32), a reproduction video processing selection (S33), a reproduction audio processing selection (S34), a processing time selection (S35),
One of the modes for selecting the pseudo multi-story (S36) is received. The work RAM 33 is associated with the code corresponding to the designated reproduction mode with the chapter.
Write in. When the processing time is selected, the processor 31 determines whether or not the time designated by the user is an appropriate value (S37), and if it is not an appropriate value, it is returned to the default value (S38).

When the user specifies "reset" in the middle of specifying the reproduction mode (S39), the reproduction mode specified up to that point is returned to the default (S40), that is, the contents written in the work RAM 33 are corrected to specify the chapter. The process returns to the step (S31). If the user has designated "decide" or "end" (S41), each reproduction mode information stored in the work RAM 33 is added to the primary text information area of the entry point information (EPI) in the designated chapter, and the entry is added. The point information is supplied to the data processing unit 15 and recorded in the management information recording area of the DVD-RAM disk 11 or the hard disk 12 (S42).

If the pseudo multi-story has been designated (S43), a flag indicating the multi-story is added to the management information of the title to which the chapter belongs (S44). If the user has designated "end" (S45), the monitor 28
The screen display of is returned to the normal display, and the editing operation ends.

Next, the operation of performing reproduction control using the entry point information after performing the above-mentioned editing work will be described with reference to FIGS. 10 and 11. Here, from the position specified by the entry point to the position of the next entry point or the end of the title, 1
Treated as one information section. Further, the control unit 30 turns on the process flag corresponding to each reproduction mode process while the process based on the reproduction mode information of the entry point information (EPI) is being executed, and sets the flag to O when the process is completed.
Set to FF. This makes it easier to manage the control of the reproduction operation.

First, FIG. 10 shows a processing flow of the reproducing operation based on the entry point information. Control unit 3 during playback
At 0, the entry point information in the management information is detected from the reproduction data supplied from the data processing unit 15 (S
51), it is determined whether or not there is a description in the primary text information (PRM_TXTI) in the entry point information (EPI) (S52), and if there is no description, default processing is performed and detection of the next entry point information is waited. If there is a description of the reproduction mode information in the primary text information, that information is analyzed, the reproduction mode information is stored in the work RAM 33, and the corresponding processing flag is turned on (S53). Here, a counter described later is reset (S54), and the process proceeds to the reproduction mode information.

First, when the reproduction mode information is described with respect to the reproduction method, the code is analyzed, and a control command for instructing a specified reproduction mode, for example, fast-forward reproduction, slow reproduction, etc., is issued to the data processing unit 15, ODD13. , H
It is supplied to the reproduction system such as the DD 14 and the decoder unit 23, and the operation of each unit in the apparatus is controlled to the designated mode (S5).
5).

Similarly, when the reproduction mode information relating to the reproduction image processing is described, the control command is supplied to the decoder unit 23, the video mixing unit 21 and the like to perform the image processing such as the negative display and the mosaic display as described above. The processed video signal is output to the monitor 28 (S56).

When the reproduction mode information relating to the audio processing is described, the control command is supplied to the decoder unit 23, the audio selector 22 and the like, and the audio signal subjected to the audio processing such as muting and echo is output to the speaker 25. Yes (S57).

Incidentally, as the individual operation processing in each reproduction mode, the processing which has been conventionally performed can be applied.

When the reproduction mode information indicating the processing time is described, the time counter (not shown) in the control unit 30 is reset to count the processing time (execution time) in each of the above reproduction modes. Start (S5
8). Further, it is determined whether or not the count value has reached the designated processing time (S60), and in the case of over-counting, the entry point processing flag is set to OFF (S60).
61) The operation in the designated reproduction mode is ended, and the normal reproduction or the default operation mode is restored.

When the reproduction mode information (identifier) relating to the pseudo multi-story is further described, the identifier is analyzed to determine whether or not to skip the information section (that is, chapter) designated by the entry point information. When skipping, the address information of the skip destination and the control command for search are sent to the data processing unit 15, O.
The search operation is performed by supplying the data to the reproduction system such as the DD 13, the HDD 14, and the decoder unit 23 (S59).

FIG. 11 schematically shows an example of the edited reproduction operation.

FIG. 11A shows the case where the reproduction method is designated as the mode. Here, in the video information of the video title, there is no particular designation at the first entry point EP # 1 and the second entry point EP # 2.
The forward slow playback is specified in. In this case, the information section in which the forward slow motion reproduction is performed is from the position of EP # 2 to the position of the next entry point EP # 3. At the next entry point EP # 3, there is no particular designation of the playback mode, which is an entry point for indicating the end position of the forward slow playback. Therefore, the default normal reproduction is resumed from the entry point EP # 3. Then, the fast-rewind reproduction is designated from the fourth entry point EP # 4, and the information section for executing the mode reaches the end of the title because there is no next entry point.

Here, the ON / OFF of the processing flag is switched for each entry point, and the execution status of the designated reproduction mode can be grasped. For example, if the reproduction mode information of the fast reverse reproduction is detected at the entry point EP # 4,
To turn on the processing flag and execute fast rewind playback,
First, a search command for skipping to the end of the title is output to the reproduction system, and then a control command for performing a fast-reverse operation is transmitted when the end position of the title is detected. Then, when the fast return reproduction to the position of the entry point EP # 4 is completed, a search command for skipping to the end of the title again is output to the reproduction system, and the processing flag is turned off. In this way, the processing flag ON / OF
Since the status of the reproduction mode processing can be determined by F, it is possible to prevent, for example, continuing the fast-reverse reproduction and returning to the previous chapter.

FIG. 11B shows the case where the reproduction video processing mode is designated. In this example, the first entry point EP # 1 in the video information of the still image title
The playback mode for negative display is specified in. in this case,
Turn on the processing flag of the entry point EP # 1,
A control command for processing for applying a negative display effect to a video signal is transmitted. Then, a still image video with a negative display effect is displayed until the end of this title, and when the end is reached, the processing flag is set to O
Set to FF.

FIG. 11C shows the case where the reproduced voice processing is mode-designated. Here, in the video information of the moving image title, since there is no designation at the first entry point EP # 1, normal reproduction is performed, and echo processing is designated at the second entry point EP # 2. The processing flag is turned on, and the echo effect processing is executed up to the position of the next entry point EP # 3. When the entry point EP # 3 is detected, the processing flag of the entry point EP # 2 is turned off. At the entry point EP # 3, since there is no particular designation of the playback mode, the default normal playback is restored.

Finally, FIG. 11D shows an example in which the pseudo multi-story mode is designated. In the video information of the moving image title, the reproduction mode information indicating the pseudo multi-story identifier "A" is recorded in the entry point EP # 2, and the reproduction indicating the pseudo multi-story identifier "B" is recorded in the entry point EP # 5. This is an example in which mode information is recorded. Entry point EP #
Since 1, EP # 3, and EP # 5 do not specify the pseudo multi-story, the information section specified by these is normal reproduction. Now, when the user plays this title,
First, the multi-story information recorded in the title management information is read, the multi-story selection menu is displayed, and the user is prompted to select a story. And
Play this title according to the user selection.

For example, when the user selects the story “A”, the entry point EP # 2 indicates the pseudo-multi-story identifier “A”, so the processing flag is turned ON at the position of the entry point EP # 2. The normal reproduction is continued, and the processing flag is turned off when the entry point EP # 3 is detected. Therefore, there is no particular change in the reproduced video here. Next, at the time of reproducing to the position of the entry point EP # 4, since the identifier "B" of the pseudo multi-story is specified in the entry point EP # 4, the processing flag is turned ON and the next entry point EP # 5 Send a search command to the playback system to skip playback to the position. Then, the processing flag is turned off when the position of the entry point EP # 5 is searched. After that, the normal playback is resumed.

Although not illustrated in FIG. 11, when the processing time is specified in the entry point information,
The processing flag of the entry point is turned ON, the time during which the special reproduction specified by other reproduction mode information is being executed is counted, and when the specified time has elapsed, the special reproduction is stopped and the normal reproduction is stopped. At the same time as returning to the reproduction, the processing flag is turned off.

Various reproduction modes as illustrated in FIG. 11 can be multiplexed and processed. For example, information starting from the entry point EP # 2 where the pseudo multi-story identifier “A” is designated. It is possible to set the section as an information section for forward slow playback.
Therefore, the entry point information (E
In PI), the primary text information area is assigned to each selection frame (category) of various reproduction modes.

As described above, in the reproduction information editing apparatus of this embodiment, it is possible to add the reproduction mode information to the entry point information for selecting the desired information section and edit the title for the playlist. When the title is reproduced, the reproduction with the special effect based on the reproduction mode information can be automatically executed, which is very convenient for the user. Also, the editing work can be executed by a simple operation because the selected reproduction mode information is automatically added to the entry point information when the desired reproduction mode is selected based on the screen display.

In the reproduction information editing apparatus of this embodiment,
The playback modes to be set include a mode related to playback speed (playback method), a mode related to processing of video information to be played back (playback video processing), a mode related to processing of audio information to be played back (playback audio processing), and selection of an information section to be played back. There is a mode (pseudo multi-story) and a mode (processing time) that specifies the processing time of these playback modes. Since these can be specified by multiplexing, various special effects can be adopted as appropriate and can be edited by the user. It is possible to expand the range of functions.

Further, according to the reproduction information editing apparatus of the present embodiment, the entry point information with the reproduction mode information and the management information (playlist information etc.) including the entry point information are recorded on the recording medium in which the corresponding video or audio information is recorded. Since the data is recorded, the edited information can be reproduced any time when the recording medium is reproduced. The information to be stored at this time is only the management information, and it is not necessary to store the edited video information itself, so that the recording medium can be used efficiently.

In the above embodiment, the entry point information added with the reproduction mode information is recorded in the recording medium such as the DVD or the hard disk and is also stored in the memory in the apparatus. If, for example, type A shown in FIG.
When the entry point information of is used, the playback mode information cannot be recorded in the format. However, even if the entry point information of type A is used, the special point as described above is edited by editing using a format like type B and storing the management information only in the memory in the device. You can edit the playback. At that time, the identification information (for example, disk number) of the recording medium on which the corresponding video information or audio information is recorded is also stored, and the recording medium to be reproduced can be collated with the corresponding title. To

Further, when the entry point is designated, or when the entry point is set to be automatically generated, specific reproduction mode information may be automatically added to the entry point information. It is possible. For example, if an entry point is set when a CM is entered during recording of a television broadcast, it is possible to automatically (as default) set a fast-forward playback mode when setting the entry point. This makes it possible to generate the same program as the edited one without any special editing work.

As described above, the embodiments of the present invention are not limited to those described above, but can be appropriately modified or applied without departing from the spirit of the present invention.

[0086]

As described above, according to the present invention,
It is possible to provide a reproduction information editing apparatus and method which can easily and efficiently perform editing for adding a special effect to a desired portion and reproducing the information when the video or audio information is edited and reproduced.

As described above, in the recording / reproducing apparatus which can be edited by the user, it is possible to reproduce a desired portion in an arbitrary order by using the playlist, but it is selected. It was not possible to edit such that a special effect was automatically added when playing a part. That is, it is impossible to pre-designate the reproduction mode, such as fast-forwarding reproduction of the selected portion, or reproduction with the voice erased. Therefore, in order to play back the original program with such special effects, the user can operate the device during playback or play the desired part from the original title once and add the special effects to it. Then, it was necessary to record again on the recording medium (the same recording medium as the original title or a different recording medium) and reproduce it by using recording information different from the original title. Therefore, there is a problem that editing work is troublesome for the user and the information recording area of the recording medium is wasted. Incidentally, the above-mentioned JP 2001-35
In the technology disclosed in No. 2519, it is possible to mark the information part to which a special effect is added by using an entry point, but the type of special effect can be specified along with this, and it can be automatically added during playback. No means of doing so have been considered.
