Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a reproducing apparatus, and more particularly to an apparatus for reproducing an information signal in accordance with reproduction list information indicating a procedure for reproducing an information signal.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, when reproducing an image signal recorded on a tape in a camera-integrated VTR, a moving image or a still image signal recorded on the tape is sequentially reproduced in the recording order.
Some commercial VTRs use a recorded scene number and a recording position of the scene to realize program reproduction.
[0003]
On the other hand, in reproduction-only video software using a disk medium such as a video CD or DVD, there is an application called interactive software. The interactive software stores a plurality of pieces of moving image information and a reproduction procedure (program) in an optical disc in advance, waits for a branch selection instruction from a user at a predetermined reproduction position according to the reproduction program, and selectively reproduces a reproduction path according to the user instruction. Things. As a specific example of the interactive software, there is a multi-story drama in which the story progress changes according to the selection result of the operator. However, the reproduction position, the selection path, and the like are programmed in advance for viewing.
[0004]
In recent years, video cameras using a disk medium as a storage medium have been commercialized. In a video camera using a disk medium, since the data of each shot scene is stored as a file in a recording medium, each scene can be accessed easily and at high speed during reproduction. Further, if the access speed of the recording information is increased, the recording / reproducing operation and the reproduction of a plurality of recording information may be simultaneously processed.
[0005]
In such a device, even if the user freely programs each recorded scene, the program can be seamlessly reproduced. The program contents are expected to be capable of reproducing complex programs such as a plurality of reproduction paths, arbitrary reproduction sections, various reproduction effect functions, and link functions at arbitrary positions and sections.
[0006]
[Problems to be solved by the invention]
In reproduction-only video software such as a video CD or a DVD using the above-described optical disk, a reproduction position, selection path information, and the like are recorded on the optical disk in advance as a program and distributed. Therefore, there is sufficient time for creating a program, and dedicated equipment can be used. In addition, since it is assumed that the program is viewed, it is possible to optimally program the program. In addition, in multi-story and interactive reproduction, it is important to create unexpected content for the user. For example, presenting a playback list before playing back the content impairs the interest of the viewer, such that the viewer can grasp the entire content before viewing the content. Therefore, there has been no method of displaying such a multi-story reproduction program or recording and editing by a user.
[0007]
On the other hand, in a video camera using a disk medium, the user can freely program each recorded scene, and the contents of the program include a plurality of reproduction paths, arbitrary reproduction sections, various reproduction effect functions, and arbitrary positions. It is feasible to create a complex program such as a section link function.
[0008]
However, when a complicated program is created, it is questioned at the time of creation of the program whether or not an optimal program has been set at the time of appreciation. If the viewer is the photographer himself, it is easy to grasp the intended program, but in other cases, the program is not always optimal. Therefore, some ingenuity is required at the time of appreciation.
[0009]
When dubbing an image signal reproduced according to a reproduction list programmed in such a complicated manner, a content desired by the user is not always reproduced. Further, it is not known whether or not the reproduction will be performed in the expected reproduction path. Further, when a problem occurs in the reproduced content, the reproduction may be stopped. For this reason, it becomes very inconvenient, for example, during dubbing reproduction, it is not possible to leave the device.
[0010]
An object of the present invention is to solve such a problem.
[0011]
Another object of the present invention is to make it possible to easily recognize a reproduction procedure when reproducing an information signal such as an image or a sound according to a reproduction list.
[0012]
Still another object of the present invention is to enable selection of an optimum reproduction path even when a plurality of reproduction paths are set by a reproduction list.
[0013]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a reproducing unit for reproducing a plurality of pieces of information data from a recording medium, and information on a plurality of playlists each showing a procedure for reproducing the plurality of pieces of information data are displayed on a display device Display control means, wherein the display control means, on the same screen, can identify a playlist having a plurality of playback paths and information of a playlist having no plurality of playback paths among the plurality of playlists. Is displayed.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described in detail with reference to the drawings.
[0015]
FIG. 1 is a diagram showing a configuration of a video camera 100 to which the present invention is applied. The video camera 100 shown in FIG. 1 uses a disk medium such as a DVD-RAM as a recording medium, and has a reproduction processing based on a reproduction list and a reproduction list editing processing function.
[0016]
First, recording processing by the video camera 100 in FIG. 1 will be described.
[0017]
The moving image signal obtained by the imaging unit 101 is output to the image signal processing unit 102 and the display control unit 108 via the bus 114. The image signal processing unit 102 encodes the moving image signal from the imaging unit 101 by a well-known compression encoding method such as MPEG, and outputs the encoded moving image signal to the disk I / F 105 via the bus 114. Further, in accordance with an instruction from the CPU 110, the display control unit 108 displays a moving image related to a moving image signal from the imaging unit 101 on the display unit 109 in the recording mode.
[0018]
On the other hand, the audio signal obtained by the microphone 103 is output to the audio signal processing unit 104 via the bus 114. The audio signal processing unit 104 encodes the audio signal by a known compression encoding method, and outputs the encoded audio signal to the disk I / F 105 via the bus 114.
[0019]
Upon receiving a recording start instruction from the operation key 111, the CPU 110 outputs control data specified in a recording format to the disk I / F 105 and records the image signal and the audio signal encoded as described above. Output a control signal to start. At this time, the control data output from the CPU 110 to the disk I / F includes information of the video camera itself, setting information such as image quality and sound quality of image signals and audio signals, and additional information relating to a shooting environment. The CPU 110 extracts an image signal of one frame from the moving image data being recorded in response to the recording start instruction, and controls the image signal processing unit 102 to generate a thumbnail image with a reduced size. The data is also output to the disk I / F 105.
[0020]
The disk I / F 105 has a well-known optical pickup, magnetic head, mechanism, etc., and records these image signals, audio signals and control data as one file on the disk D under file system management such as UDF and FAT. I do. The file system means a structure type consisting of management information for managing files and file data.By sharing this file system, information can be recorded on different storage media or recording / reproducing devices. Can be played.
[0021]
In the present embodiment, a disk D is used as a recording medium, and management information in the file system is recorded in a predetermined area of the disk D, for example, a predetermined management area on the innermost circumference. The disk I / F 105 includes management information in the management area, a disk ID, an attribute of each file, a recording position (sector or track) of file data, thumbnail image data of each file, group management data of each file, and shooting information. Record additional information at the time. The file of image data and audio data is recorded in an area other than the management area.
[0022]
After the start of recording, when there is a recording stop instruction from the operation keys 111, the CPU 110 instructs the disk I / F 105 to stop recording. The disk I / F 105 stops the recording of the image signal and the audio signal in accordance with the recording stop instruction, and sets each data recorded on the disk D from the start of the recording to the stop of the recording as one file.
[0023]
In the recording mode, an image signal from the imaging unit 101 or an image signal encoded by the image signal processing unit 102 is output to the external I / F 113 via the bus 114, and the external I / F 113 transmits the image signal to an external device. It is also possible to output them.
[0024]
Next, the still image recording mode will be described. Also in the still image shooting mode, the image related to the moving image signal obtained by the imaging unit 101 is displayed on the display unit 109 by the display control unit 108. When a still image recording instruction is issued from the operation keys 111 in this state, the CPU 110 extracts an image signal of one frame from a moving image signal from the imaging unit 101 and outputs the image signal to the image signal processing unit 102. The image signal processing unit 102 encodes the one-frame image signal by a known compression encoding method such as JPEG and outputs the still image data to the disk I / F 105 via the bus 114. The CPU 110 controls the image signal processing unit 102 to generate thumbnail image data in which the size of the still image data is reduced, and outputs the thumbnail image data generated by the image signal processing unit 102 to the disk I / F 105.
[0025]
The disk I / F 105 records the encoded still image signal of one frame and the control data from the CPU 110 as one file on the disk D, and stores management information in a predetermined area of the disk D as in the moving image recording mode. Record.
[0026]
Next, a normal reproduction operation of a moving image file or a still image file recorded as described above will be described.
[0027]
When a reproduction mode is instructed by the operation key 111, the CPU 110 controls the disk I / F 105 to reproduce the management information from the disk D. The disk I / F 105 reproduces the management information from the disk D and outputs it to the CPU 110. The CPU 110 stores the management information in the memory 112, detects the thumbnail image data of each file from the management information, and outputs the thumbnail image data to the image signal processing unit 102. Then, the thumbnail image data is decoded by the image signal processing unit 102 and sent to the display control unit 108.
[0028]
Then, the CPU 110 controls the display control unit 108 to display a plurality of thumbnail images on the same screen.
[0029]
The user operates the operation key 111 to select a thumbnail image of a file desired to be reproduced from a plurality of thumbnail images displayed on the display unit 109, and instructs reproduction. Then, the CPU 110 reproduces a file corresponding to the designated thumbnail image from the disk D, decodes the file by the image signal processing unit 103, and displays the decoded image on the display unit 109 by the display control unit 108.
[0030]
Next, the reproduction operation by the reproduction list file is controlled.
[0031]
The play list file is a list file (which can be realized by a binary file) specifying a play procedure of an information file such as an image and a sound recorded on the disk D, and has an arbitrary play path, an arbitrary play section, and a variety of play. It describes an effect function, a link function at an arbitrary position or section, and the like.
[0032]
FIG. 2 shows an example of the playlist file.
[0033]
In the example of FIG. 2, the first line indicates that a playback operation is instructed from the <Play> to the <PlayEnd> tag on the 14th line, and the second line indicates that the moving image 01 file is 200 seconds from the position 5 seconds after the beginning. This indicates that normal reproduction is performed and the process moves to the label <Level1> on the tenth line. The third line is the fourth line <1>, the fifth line <2>, and the seventh line <3> from the <Action> tag to the <End of Action> tag by a user operation during reproduction of the moving image 01 file. It represents branching to either.
[0034]
In <1> on the fourth line, all of the moving image 02 files are reproduced, and the process proceeds to <Level 2> on the twelfth line. In <2> on the fifth line, the still image 03 file is reproduced for 5 seconds, then the moving image 07 file is reproduced for 10 seconds, and the process proceeds to <Level 2> on the twelfth line. In <3> on the seventh line, all of the moving image 07 files are reproduced, and then all of the moving image 08 files are reproduced, and the process proceeds to <Level 2> on the twelfth line.
[0035]
The eleventh line indicates that the still image 01 file is reproduced for 15 seconds, and the thirteenth line indicates that all the moving image 10 files are reproduced. Then, on the 14th line, all reproduction processing ends.
[0036]
Although not shown in the example of FIG. 2, the play list file can also describe the angle of view, the size, the layer, the effect, the scene change effect, the overlap effect, the combined reproduction of images, sounds, texts, and the like.
[0037]
The video camera 100 according to the present embodiment has a function capable of generating a simple playlist, and the user designates a playback order or a special effect for a file recorded on the disc D in the playlist editing mode to create a playlist. Can be generated. The generated playlist is sent from the COU 110 to the disk I / F 105 and recorded on the disk D.
[0038]
Further, a more complicated playlist as described later can be generated by another device such as a personal computer. The playlist thus generated is sent to the disk I / F 105 via the external I / F 113 and is stored in the disk D. Be recorded.
[0039]
When the user issues a playlist playback instruction in a state where a plurality of playlists are recorded on the disc D, the CPU 110 controls the disc I / F 105 to reproduce management information on the playlist file from the disc D. Stored in the memory 112. Then, the display control section 108 is controlled to display a list screen of the playlist files recorded on the disk D on the display section 109.
[0040]
FIG. 3 is a diagram showing a list screen 300 of a playlist. In FIG. 3, reference numeral 301 denotes a slider bar for indicating the position of the playlist when the entire playlist cannot be completely displayed on the list screen. Reference numeral 302 denotes information indicating the content of the playlist. Displays the creation date. As the information 302, it is also possible to display the total playback time of the input information file specified in the playlist, the attribute of the playlist, the subtitle, the comment, the information of the creator, and the representative image of each playlist file. It is. Reference numeral 303 denotes information indicating the currently selected reproduction list, and reference numeral 504 denotes information indicating the number of reproduction paths in the reproduction list. For example, “LINK / ROOT: 2” indicates that there are two playback paths.
[0041]
When the user operates the operation keys 111 while selecting such a list screen and selects one desired playlist, the CPU 110 plays the designated playlist file from the disk D and stores it in the memory 112. Then, the content is confirmed, and the display control unit 108 is controlled to display a screen showing the content of the selected playlist on the display unit 109.
[0042]
For example, when a play list of “athletic meeting 003.plf” having a plurality of playback paths is selected in FIG. 3, a screen 400 showing the contents is displayed on the display unit 109 as shown in FIG.
[0043]
In FIG. 4, reference numeral 401 denotes information on a file designated in the playlist file, and can display a file name, a playback time, a file attribute, a subtitle, a comment, a creator, effect information, and the like. FIG. 4 shows only the file name. Reference numeral 402 denotes a final file, which is displayed in a display form that can be distinguished from other files. The playback order between the files is indicated by an arrow.
[0044]
For example, in the example of FIG. 4, a playback path of “movie 01 → still image 01 → movie 10”, a playback path of “movie 01 → movie 02 → movie 10”, and a “movie 01 → still picture 03 → still picture 07 → movie” 01 "and four reproduction paths of moving image 01, moving image 07, moving image 08, and moving image 10".
[0045]
Also, at this time, when a large number of files are specified in the playlist and all the files cannot be displayed at once, or when displaying all the files on the display unit 109 makes it difficult to see, for example, It is also possible to display as shown in FIG. 5 or FIG.
[0046]
FIG. 5 and FIG. 6 show the contents of a play list file “athletic meeting 006.plf”. This playlist file specifies a large number of information files, and if the contents of all the specified files are to be displayed on the display unit 109, the size must be reduced, which makes it difficult to see. Is displayed in approximately four parts.
[0047]
FIG. 5 is a diagram showing one of the four split screens 500, and 502 and 503 are slider bars each indicating a display position. Reference numeral 503 denotes information indicating the position of the display screen 500 in the entire screen of the playlist file.
[0048]
When the user instructs full-screen display, the entire contents of the playlist file are displayed on the display unit 109 as shown in FIG. On the display screen 600 in FIG. 6, the quadrant screen 500 in FIG. 5 is displayed in a distinguishable state.
[0049]
Next, a process of selecting one reproduction path from a plurality of reproduction paths will be described.
[0050]
When an instruction to display a route selection screen is given by the operation keys 111 while the content screen of the playlist is displayed as shown in FIG. 4, the CPU 110 controls the display control unit 108 to display the route selection screen shown in FIG. Displayed at 109. As shown in FIG. 7, the currently selected playback path is displayed as a bold line, and the user operates the operation key 111 to select an arbitrary playback path from a plurality of playback paths. Can be.
[0051]
It should be noted that it is also possible to store the information of the selected reproduction route as additional information of the reproduction list in the reproduction list file.
[0052]
After confirming the contents of the play list file, setting the play path if necessary, and then instructing the start of the play by the user, the CPU 110 executes the contents of the play list stored in the memory 112. Controls the disk I / F 105 and the image signal processing unit 102 to reproduce each file from the disk D in accordance with the above.
[0053]
FIG. 8 is a view showing a state of a screen displayed on the display unit 109 when the reproduction is performed according to the reproduction list file “athletic meeting 003.plf” in FIG. On the display screen of FIG. 8, for example, during playback of the file of the moving image 01, three files of the moving image 04, the moving image 05, and the still image 04 can be selected. It is displayed at the bottom of the screen. In addition, information 801 indicating that a plurality of reproduction paths are set is displayed in this reproduction list.
[0054]
Here, if the reproduction path has not been selected by the user in advance, the CPU 110 displays on the display unit 109 warning information prompting the selection of the next reproduction path at the timing when the reproduction path branches. In this case, the user selects one of the next reproduction candidate files displayed at the lower part of the display screen with the operation keys 111 to determine the next reproduction path.
[0055]
If the next reproduction path is not instructed before the end of the information file currently being reproduced, the reproduction operation is suspended at that point and the user waits until the next file is selected.
[0056]
As described above, when the reproduction path is not selected in advance, the user can arbitrarily select the next reproduction file at the branch point of the reproduction path.
[0057]
As described above, when a plurality of reproduction paths are set in the reproduction list, the user can arbitrarily select a reproduction path. However, when there are a plurality of reproduction lists, the user sets the reproduction path each time. This can be bothersome. Therefore, in the present embodiment, a function is provided for automatically selecting a reproduction path according to a predetermined condition.
[0058]
For example, it has a function of automatically selecting a reproduction path based on a user's operation history as a first selection condition. That is, in this case, the CPU 110 accumulates the history of the reproduction path selected by the user in the past with respect to the reproduction list file in the memory 112, and automatically reproduces the reproduction path file based on the reproduction path history. Select a playback path.
[0059]
Further, the type of the information file specified in the playlist can be used as the second selection condition. For example, among the information files specified in the playlist, a configuration in which only a video file is reproduced, or a configuration in which a file including only audio is selected and reproduced is conceivable. Further, it is also possible to select and reproduce only a specific type of file according to the type of additional information added to each file.
[0060]
Furthermore, it is also possible to select a reproduction path that contains the most files of a specific type, or, conversely, a reproduction path that contains the least number of files of a specific type. Further, it is possible to select a reproduction path in which several types of files are included at a predetermined ratio.
[0061]
For example, by setting such automatic playback when the user performs playback according to the playlist file, there is no need for the user to select a playback path.
[0062]
Now, as an application example of a system using a video camera as in the present embodiment, dubbing by connecting the video camera 100 to another recording device can be considered.
[0063]
At this time, the information data reproduced according to the reproduction list can be transmitted to the recording device and dubbed.
[0064]
At this time, if a plurality of playback paths are set in the selected playlist, according to the present embodiment, if the user selects a playback path in advance and starts dubbing as shown in FIG. Since it is set, the user does not need to air to the place after dubbing starts.
[0065]
If the user inadvertently starts dubbing without selecting a playback path in advance, the CPU 110 automatically selects a playback path in accordance with the predetermined condition as described above, and Even if there is no standby, the automatic reproduction process using the reproduction list file does not stop, and good dubbing can be performed.
[0066]
In the case of performing dubbing, as shown in FIG. 9, the external I / F of the video camera 100 ′ having the same configuration as the video camera 100 of FIG. The reproduced image data and audio data are transmitted to the video camera 100 'as a stream analog signal and recorded. At this time, a control signal such as a recording start command is exchanged between the video cameras 100 and 100 '. The control signal is transmitted and received as digital data through an IEEE 1394 interface or the like.
[0067]
Next, reproduction processing by the video camera 100 including such dubbing processing will be described with reference to the flowchart of FIG.
[0068]
FIG. 10 is a flowchart showing a control operation by the CPU 100 in the reproduction mode. When the reproduction mode is set, first, the management information is reproduced from the disk D (step S1001), and then, it is detected whether or not the user instructs the reproduction by the reproduction list (step S1002). Here, when the reproduction by the reproduction list is not instructed, the normal reproduction process is performed (step S1021).
[0069]
If the reproduction by the reproduction list has been instructed, it is further detected whether or not the dubbing mode has been set (step S1003). When the dubbing mode is set, it is determined whether or not there is a file whose reproduction is prohibited (copy prohibition) in the disc D (step S1004). If the reproduction prohibition file is included, the fact is indicated on the display unit 109. The display is completed, and the reproduction process ends. If the reproduction prohibition file does not exist, information indicating that the dubbing mode has been set is displayed (step S1005).
[0070]
Thereafter, a list of playlists is displayed as shown in FIG. 3 (step S1006), and the process waits until a playlist is selected by the user (step S1007). When the reproduction list is selected, the contents are analyzed (step S1008), and it is determined whether or not there is a problem in performing the reproduction (step S1009). Here, if there is a defect such as a defect of the file information, a defect of the stream in the file, or a defect of the reproduction path instruction, the defect is repaired as much as possible. If there is a defect that cannot be solved even by this repair work, alternative processing such as replacing the file itself, skipping unreproducible data, and switching the reproduction path is performed. Then, the fact is displayed on the display unit 109 (step S1010).
[0071]
After analyzing such a playlist, the structure of the playlist is displayed as shown in FIG.
[0072]
Next, it is detected whether or not there is a plurality of reproduction paths in the selected reproduction list, and if there is only one reproduction path, reproduction according to the reproduction list is started immediately after waiting for a user's instruction.
[0073]
Further, when a plurality of reproduction paths are set, a manual path selection by the user is further detected (step S1013), and when a reproduction path image is manually selected, reproduction is started on the selected reproduction path (step S1013). S1017). In addition, when the reproduction path is not manually selected, the apparatus further detects whether the dubbing mode is set, and when the dubbing mode is set, the reproduction path is automatically set according to the plurality of conditions as described above. A selection is made (step S1016). Then, the reproduction is started after waiting for the reproduction start (dubbing start) instruction from the user (step S1017).
[0074]
If the dubbing mode is not set, it is determined whether or not the automatic path selection mode is set. If the automatic selection mode is set, the reproduction path is automatically set according to the plurality of conditions as described above. (Step S1016). Then, the reproduction is started after waiting for a reproduction start instruction from the user (step S1017).
[0075]
At this time, the CPU 110 constantly monitors whether or not a problem occurs during reproduction. If a problem occurs, the CPU 110 repairs the problem as much as possible, and if necessary, takes measures such as changing the reproduction path.
[0076]
If the automatic path selection mode is not set, the user sets the manual selection at the branch point of the reproduction path, and starts reproduction.
[0077]
Thereafter, when the reproduction processing according to each reproduction list ends (step S1018), the processing in the reproduction mode ends.
[0078]
As described above, in the present embodiment, when performing reproduction by a play list, the structure of a plurality of play lists recorded on the disc is analyzed and displayed, so that the contents of the play list selected by the user (playback procedure) Can be easily grasped. Also, at the time of displaying the list of playlists, since the playlist having a plurality of playback paths is displayed so as to be identified, the user can easily recognize the playlist having a plurality of playback paths.
[0079]
In addition, since a playback path for a playback list having a plurality of playback paths can be selected in advance before the playback is started, the playback processing is not interrupted each time at a branch point after the playback is started, so that the playback process is comfortable. Reproduction processing can be realized.
[0080]
In addition, in the case where the user does not select a reproduction path by automatically selecting and reproducing the reproduction path in accordance with predetermined conditions such as a past operation history and a specified file type, for a plurality of reproduction paths. However, the reproduction processing according to the reproduction list can be realized on the optimum reproduction path.
[0081]
In addition, when dubbing data reproduced according to the playlist, if the user does not set a reproduction path, the reproduction path is automatically selected. And dubbing can be performed by selecting an optimal reproduction path, thereby preventing a breakdown.
[0082]
In the above-described embodiment, a playlist having a plurality of playback paths is selected. However, when a playback path is not manually selected, a playback path is automatically selected in step S1016 in FIG. In the dubbing mode, the reproduction according to the reproduction list and the dubbing process may be prohibited unless the reproduction path is selected by the user.
[0083]
In this case, as shown in the flowchart of FIG. 11, when the reproduction path is not manually selected in step S1013 and the dubbing mode is set in step S1014, it is determined that dubbing is not possible because the reproduction path is not set. The information is displayed, and the reproduction process is stopped (step S1022). Other processes are the same as those in FIG.
[0084]
As described above, in the dubbing mode, when a playlist having a plurality of playback paths is selected, the user is prohibited from performing dubbing without selecting a playback path, thereby preventing careless dubbing. can do.
[0085]
In the above embodiment, the case where the present invention is applied to an apparatus for recording and reproducing image data on an optical disk medium has been described. However, other than this, a semiconductor memory medium such as a memory card or other sound random The present invention can be similarly applied to an apparatus that records and reproduces information data such as image data on an access medium and reproduces the information using a reproduction list, and has the same effect.
[0086]
【The invention's effect】
As described above, according to the present invention, since the information of a playlist having a plurality of playback paths is displayed, when an information signal such as an image or a sound is played according to the playlist, the playback procedure can be easily recognized. It becomes.
[0087]
Further, according to another invention of the present application, a plurality of playback paths included in the playlist are displayed, and an arbitrary playback path can be selected from the plurality of playback paths. Even if the player is in the position, the optimum reproduction path can be selected.
