Abstract

PROBLEM TO BE SOLVED: To eliminate the need for storing the history of a channel once selected by means of a memo or the like by storing the history of a channel having been selected by the user in a multi-channel block appearing after a reproduction start point in the case of using a program search function. SOLUTION: In the case of reproducing a history, a CPU monitors whether image information being reproduced at present is resident in a multi-channel block or at the other position of the block. When the image information being reproduced comes round the multi-channel block, a history reproduction flag 301 is set, the CPU reads a prescribed multi-channel block address 308 and a selection channel number 309 from a reproduction history recording area 307 of a memory and provides a corresponding selection channel. In the case that the user selects an optional channel by using a ten-key on the operation panel, the selected channel is reproduced. Thus, it is possible to select a channel in the multi-channel block even during reproduction of a history.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a digital versatile disk (DVD) on which image information and audio information are recorded as digital information.
In particular, the present invention relates to an image reproducing apparatus for reproducing an optical information recording medium such as an image reproducing apparatus for reproducing image information having at least one multi-channel block in which an image progressing in the same time is recorded in a plurality of channels. Related to the device.

[0002]

2. Description of the Related Art In recent years, as a result of rapid advances in digital signal processing technology, optical disk manufacturing technology, image compression technology, and the like,
DVD has been developed as a new optical information recording medium that is compact, multifunctional and has high image quality, and has begun to spread on the market. D
A DVD playback device for playing back VD has a chapter search function and a fast-forward / fast-return function that can search for each scene of a recorded image, and the like, as compared with conventional media.

[0003] In addition to the above functions, DVDs and DVD playback devices have a multi-angle function that allows the same scene to be viewed from different angles, a multi-story function that allows the user to select a story, and the like. I have. In the present application, these multi-angle functions and multi-story functions are called multi-channel functions and will be described below. FIG.
FIG. 3 is a schematic diagram illustrating a multi-channel function.

[0006] The multi-channel function means that, as shown in FIG. 6, images progressing in the same time are recorded in a plurality of channels in image information recorded on a DVD, and the user can arbitrarily operate the DVD reproducing apparatus. This function allows you to select a channel.

In order to realize the multi-channel function, it is necessary to set a plurality of special cells called multi-channel blocks in a track on which image information is recorded. In FIG. 6, three channels (1), (2),
The figure shows image information having a multi-channel block A having (3) and a multi-channel block B having three channels (4), (5) and (6). Here, since the channels in the same multi-channel block advance at the same time, their recording times need to be the same.

For example, while reproducing the image information shown in FIG.
When approaching multi-channel block A, DV
The D playback device indicates that the block is a multi-channel block on a screen (not shown), and informs the user that the section can be switched to another channel. At this time, the user can select an arbitrary channel from the three channels (1), (2), and (3).

When the reproduction of the multi-channel block A has been completed and the reproduction of the image information has further progressed and the multi-channel block B has been reached, the DVD reproducing apparatus indicates again that the block is a multi-channel block on the screen.
Similarly, during this section, the user can select any channel from the three channels (4), (5), and (6).

If the user selects a channel in the multi-channel block, a channel specified in advance in the image information recorded on the DVD or a channel automatically specified by the DVD reproducing apparatus (for example, The channels (1) and (4) in FIG. 7 are reproduced. This function is called default playback.

[0009]

A conventional DVD reproducing apparatus specifies a reproduction start point for an arbitrary scene of image information recorded on a DVD and reproduces the image information again from the reproduction start point. It has a cueing function that can be performed. However, during reproduction of a DVD having a multi-channel function, a reproduction start point is set at an arbitrary scene, and an arbitrary channel is selected in a multi-channel block appearing after the reproduction start point without performing default reproduction. When the reproduction is started from the reproduction start point again by using the cue function after the reproduction (previous reproduction), channel selection is performed in a multi-channel block appearing after the reproduction start point. If not, the DVD playback device performs default playback, so that there is a problem that a channel different from the previous playback is played.

Therefore, if the user wants to watch the same channel after the reproduction start point, the user must select the same channel again each time a multi-channel block is reached, which is troublesome. When the program time after the reproduction start point is long and the number of multi-channel blocks is large, it is difficult for the user to memorize the previously selected channel in all the multi-channel blocks. Such a problem is very inconvenient as the usability of the image reproducing apparatus,
It may be a factor that hinders the spread of the new media called D.

[0011]

According to a first aspect of the present invention, there is provided an image processing apparatus having at least one multi-channel block in which an image progressing in the same time is recorded by a plurality of channels.

According to the image reproducing apparatus of the present invention, an arbitrary reproduction start point of the image information recorded on the optical information recording medium is designated, and the reproduction of the image information is restarted from the reproduction start point. When a cue function that can be performed is used, the history of the channel selected by the user in the multi-channel block appearing after the reproduction start point can be stored. Therefore, the user does not need to take notes and store the history of the selected channel.

According to the image reproducing apparatus of the second aspect of the present invention, when the image information is reproduced using the cueing function, the user automatically selects the channel previously selected in the multi-channel block appearing after the reproduction start point. It can be played back. Therefore, every time the user approaches the multi-channel block, the previously reproduced channel can be reproduced without selecting a channel again.

According to the image reproducing apparatus of the third aspect of the present invention, the image information is reproduced using the cue function, and the channel selected by the user last time is automatically reproduced for the multi-channel block after the reproduction start point. Even when the reproduction is performed using the history reproduction function, when the user selects a channel different from the previously selected channel in an arbitrary multi-channel, the newly selected channel can be reproduced.

According to the image reproducing apparatus of the fourth aspect of the present invention, when the user reproduces the history of the image information again by using the cue function, whether the user automatically reproduces the previously selected channel, You can choose whether to play the default.

According to the image reproducing apparatus of the present invention, when the user reproduces the history of the image information again by using the cue function, the user automatically reproduces the previously selected channel. Even if the default playback is selected without selection, the history of the channel previously selected by the user is retained in the channel storage means without being erased, so that the previously selected channel is automatically played back at any time can do.

For example, when the user wants to start playback from the playback start point numbered 3rd, the user presses the history playback start button 203 and further presses the 3 key of the 10 key 205 to play back the numbered 3rd number. Start playback from the start point.

The default playback instruction button 204 performs playback from the playback start point, and is used simultaneously with the history playback start button 203 when the default playback is desired. In this embodiment, a small default playback instruction button 204 is provided as a part of the history playback start button so that both the case where the history playback start button 203 is pressed alone and the case where the history playback start button 203 is pressed simultaneously with the default playback instruction button 204 are easily performed. . If the default reproduction instruction button 204 is pressed, the history reproduction start button 203 is also pressed. Alternatively, the default reproduction may be performed by pressing the default reproduction instruction button 204 alone.

When the default playback instruction button 204 is pressed at the same time as the history playback start button 203, in the multi-channel block appearing after the playback start point, the channel specified in the image information recorded on the DVD 101, Alternatively, a channel automatically designated by the DVD reproducing device is reproduced (default reproduction). Also, when the multi-channel block is approached during the default reproduction, the DVD reproducing device indicates the multi-channel block on the screen and informs the user that the channel can be switched. At this time, the user can select an arbitrary channel with the 10 key 205.

Next, the configuration of the memory 114 of the image reproducing apparatus of the present invention will be described with reference to FIGS. FIG.
FIG. 3 is a schematic diagram showing one embodiment of a format of a history reproduction area on a memory of the image reproduction apparatus of the present invention.

As shown in FIG. 3, the memory 114 has an area for storing a history reproduction flag 301 and a default flag 302. Here, the history reproduction flag 301 is ON.
In the case of, in the multi-channel block appearing after the reproduction start point, history reproduction for reproducing the same channel as the channel selected by the user at the previous reproduction is performed. When the default flag is ON, the DVD 101
In this case, a default reproduction is performed in which a channel specified in advance in the image information recorded in the DVD or a channel automatically specified by the DVD reproducing apparatus is reproduced.
The history reproduction flag 301 is turned on when the history reproduction start button 203 of the operation panel 115 is pressed, and the default flag 302 is turned on when the default reproduction instruction button 204 of the operation panel 115 is pressed.

The memory 114 has an area for recording a reproduction start point number 303, a reproduction start point address 304, still image data 305, and a history flag 306. The reproduction start point number 303 is a number assigned to a reproduction start point arbitrarily selected by the user. When the reproduction start point setting button 201 of the operation panel 115 is pressed, the CPU 113 starts numbering in the order of pressing. Will be appended.

The reproduction start point address 304 is the address of the reproduction start point arbitrarily selected by the user, and the still image data 305 is the frame data at the reproduction start point. The history flag 306 is a flag for determining whether or not to record the history of the channel selected by the user in the multi-channel after the reproduction start point in the memory 114. The reproduction start point setting button 201 of the operation panel 115 Turns on when pressed.

Further, the memory 114 has a reproduction history recording area 307 for recording the history of the channel selected by the user in the multi-channel block after the reproduction start point. In this area, a multi-channel block address 308, which is the address of a multi-channel block appearing after the reproduction start point, and a selected channel number 309, which is the number of the channel selected by the user in the multi-channel block, are recorded. Since a plurality of multi-channel blocks may exist after the playback start point, the playback history recording area 307
Can record a plurality of multi-channel blocks.

The memory 114 can record a plurality of data sets from the reproduction start point number 303 to the reproduction history recording area 307 in case a plurality of reproduction start points are set.

Next, the operation of the image reproducing apparatus of the present invention will be described with reference to FIGS. 1, 2, 3, 4 and 5.
FIG. 4 is a flowchart showing the operation of setting / releasing the reproduction start point of the image reproducing apparatus according to one embodiment of the present invention. FIG. 5 is a diagram illustrating channel selection in a multi-channel block of an image reproducing apparatus according to an embodiment of the present invention;
6 is a flowchart illustrating an operation of recording a history and reproducing the history.

First, the operation of setting and canceling the reproduction start point will be described. As shown in FIG. 4, when the reproduction is started (S1) and the reproduction start point setting button 201 of the operation panel 115 is pressed at an arbitrary point (S1).
2), the CPU 113 records the reproduction start point number 303, the reproduction start point address 304, and the still image data 305 in the memory 114, and turns on the history flag 306.
(S3). After that, the reproduction history is recorded.

When the reproduction start point is set for the first time,
The reproduction start point number 303 becomes 1, and if it is the second or subsequent time, the number of the number is automatically added. At this time, the still image data 305 of the playback start point may be displayed on the screen (or normally not displayed, and displayed only when a plurality of points are set when the history playback start instruction is issued). In S2, when the reproduction start point is not set, the history flag 306 remains OFF,
Reproduction is continued without recording in the memory 114.

To release the set reproduction start point (S4), the user presses the reproduction start point release button 202 on the operation panel 115. Play start point release button 202
When is pressed, the CPU 113 turns off the history flag 306 of the area for history reproduction in the memory 114. However,
The operation differs depending on the number of recorded playback start points. When there are a plurality of recorded reproduction start points (S5), it is necessary to input which reproduction start point is to be canceled. Play start point release button 20
The user inputs the number assigned to the still image data 305 displayed on the screen using the 10 key 205 in conjunction with 2 (S
6). If the number of set playback start points is one, it is not necessary to input a number, so simply pressing the playback start point release button 202 turns the history flag 306 ON.
F (S7).

Next, the operation of selecting a channel in the multi-channel block, recording the history, and reproducing the history will be described. First, an operation in the case where the user performs normal reproduction without setting a reproduction start point will be described.
As shown in FIG. 5, while reproducing the image information recorded on the DVD 101, the CPU 113 monitors whether the image being reproduced is a multi-channel block or a part other than the multi-channel block (S8). For normal playback,
Since the reproduction start point setting button on the operation panel 115 is not pressed, the history flag 306 is OFF, so that the reproduction is continued (S24).

The image information during normal reproduction reaches the multi-channel block, and the user
When an arbitrary channel is selected by the 0 key 205 (S9), the selected channel is reproduced (S1).
0). If the channel is not selected, the history reproduction flag 301 is OFF, so that the default reproduction is performed (S13). In the case of normal reproduction, this routine is repeated for each multi-channel block until a reproduction stop command is issued. During normal playback, the default playback instruction button 204 on the operation panel 115 is not pressed, so the default flag 302 of the memory 114 is ON as an initial value (S14), but the playback start point setting button 201
Has not been pressed, the history flag 30
Since 6 is OFF, the history of the selected channel in the multi-channel block is not recorded.

During reproduction of the image information, the user operates the operation panel 1
A case will be described in which the reproduction start point is set by pressing the 15 reproduction start point setting button 201 and the history recording is performed. When the reproduction start point setting button 201 is pressed, the history flag 306 of the memory 114 is turned on. Then, the history recording starts, and the CPU 113 monitors whether the currently reproduced image is a multi-channel block or a part other than the multi-channel block (S8). In portions other than the multi-channel block, the CPU 113
Checks whether the history flag 306 of the memory 114 is ON or OFF (S24). In this case, since the history recording is being performed, the history flag 306 is ON, but if there is no instruction to perform the reproduction from the reproduction start point, the reproduction is continued (S1).
7). When a reproduction command is issued from the reproduction start point, the history recording is immediately stopped, and a reproduction routine is started from the reproduction start point. The reproduction routine from the reproduction start point will be described later.

When the image information being reproduced reaches the multi-channel block and the user selects an arbitrary channel with the 10 key 205 of the operation panel 115 (S
9) Play the selected channel (S10). If no channel is selected, the history playback flag 3
01 is OFF, the default reproduction is performed (S1
3). In the case of history recording, until there is a command to stop playback,
This routine is repeated for each multi-channel block.

During the history recording, the default reproduction instruction button 204 of the operation panel 115 is not pressed, so the default flag 302 of the memory 114 is OFF (S14), but the reproduction start point setting button 201 of the operation panel 115 is not operated. The history flag 306 is set to O
Since it is N (S15), the history of the selected channel in the multi-channel block is recorded (S16).
That is, the multi-channel block address 308 and the selected channel number 309 are recorded in the reproduction history recording area 307 of the memory 114. As described above, the image reproducing apparatus of the present invention can record the history of the channel selected by the user in the multi-channel.

Next, a case where reproduction is performed from the reproduction start point will be described. The user selects whether to perform reproduction from the reproduction start point set by himself (S17). When performing playback from the playback start point, the operation differs depending on whether one or more set playback start points exist. If there is only one playback start point (S18), the history playback start button 2 on the operation panel 115
When 03 is pressed, the CPU 113 reads the reproduction start point address 304 recorded in the memory 114.

If there are a plurality of playback start points (S18), the history playback start button 2
By pressing the 03 and 10 keys 205, a desired reproduction start point is selected (S19). The reproduction start point may be selected with reference to the still image data 305 of each reproduction start point displayed on the screen. When an arbitrary reproduction start point is selected, the CPU 113 reads the reproduction start point number 303 recorded in the memory 114,
The reproduction start point address 304 corresponding to the corresponding reproduction start point number 303 is read.

If the default playback instruction button 204 on the operation panel 115 is not pressed at the same time as the history playback start button 203 (S20), the CPU 113 turns on the history playback flag 301 recorded in the memory 114.
And the default flag 302 is turned off (S2
1). When the default playback instruction button 204 is pressed simultaneously with the history playback start button 203 (S2
0), the CPU 113 turns off the history reproduction flag 301 recorded in the memory 114 and sets the default flag 3
02 is turned ON (S22).

Then, the CPU 113 controls a servo circuit (not shown) of the DVD format decoder 104 to
The optical pickup 103 is moved to the selected reproduction start point (S23).

Returning to S8, the image information after the reproduction start point selected by the optical pickup 103 is read. When the history reproduction flag 301 is OFF and the default flag 302 is ON, default reproduction is performed. When the history playback flag 301 is ON and the default flag 302 is OFF, history playback is performed.

In the case of history reproduction, the CPU 113 monitors whether the image information currently reproduced is a multi-channel block or a part other than the multi-channel block (S8).
If the image information currently being reproduced is not a multi-channel block, the CPU 113 checks whether the history flag 306 of the area for history reproduction in the memory 114 is ON or OFF (S
24). In this case, since the history reproduction is being performed, the history flag 306 is ON, but if there is no instruction to perform the reproduction from the reproduction start point, the reproduction is continued (S17). When a reproduction command is issued from the reproduction start point, history reproduction is immediately stopped, and a reproduction routine from a new reproduction start point is started.

When the image information being reproduced reaches the multi-channel block (S8), the history reproduction flag 30
Since 1 is ON, the channel is selected and reproduced according to the history recorded in the memory 114 (S12).
07 to a predetermined multi-channel block address 30
8 and the selected channel number are read, and the AV decoder 107 is controlled to output the corresponding selected channel.
When the user selects an arbitrary channel using the 10 key 205 of the operation panel 115 (S9), the selected channel is reproduced (S10). As described above, the image reproducing apparatus of the present invention can select a channel in a multi-channel block even during history reproduction.

During history reproduction, since the default flag 302 of the memory 114 is OFF and the history reproduction flag 301 is ON (S14), the history of channel selection is recorded in the memory 114 (S16). Therefore, the image reproducing apparatus of the present invention can rewrite the history of the history reproduction.

In the case of default reproduction, the CPU 11
3 monitors whether the currently reproduced image information is a multi-channel block or a part other than the multi-channel block (S8). If the currently reproduced image information is not a multi-channel block, the CPU 113 checks whether the history flag 306 of the memory 114 is ON or OFF (S2).
4). In this case, since the history reproduction is being performed, the history flag 306 is ON, but if there is no instruction to perform the reproduction from the reproduction start point, the reproduction is continued (S17). When a reproduction command is issued from the reproduction start point, history reproduction is immediately stopped, and a reproduction routine from a new reproduction start point is started.

When the image information being reproduced reaches the multi-channel block (S8), if the user does not select a channel, the default reproduction is performed because the history reproduction flag 301 is OFF. The user operates the operation panel 11
When an arbitrary channel is selected by the 5 10 key 205 (S9), the selected channel is reproduced (S9).
10).

[0060]

According to the image reproducing apparatus of the present invention, an arbitrary reproduction start point of the image information recorded on the optical information recording medium is designated, and the reproduction of the image information is started from the reproduction start point. Even when the cueing function that can perform the re-recording is used, the history of the channel selected by the user for the multi-channel block after the reproduction start point can be stored. Therefore, there is no need to store the history of the channel previously selected by the user in a memo or the like.

According to the image reproducing apparatus of the second aspect of the present invention, the channel selected by the user last time can be automatically reproduced for the multi-channel block after the reproduction start point. Therefore, it is not necessary to select a channel again each time the user approaches the multi-channel block, so that the history can be easily reproduced.

According to the image reproducing apparatus of the third aspect of the present invention, the image information is reproduced by using the cue function, and the channel previously selected by the user for the multi-channel block after the reproduction start point is automatically reproduced.
