Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus, a program, and a recording medium. It is about media.

[0002]

2. Description of the Related Art Conventionally, images such as television programs have been recorded and recorded.
Video tapes are commonly used as media to be played. Due to its structure, video tapes cannot record and play back at the same time, and cannot instantly play back a recorded video (program) of interest.

In recent years, instead of the above-mentioned video tape, media used for recording and reproducing video such as television programs have been
Hard disk (HD) and DVD (Digital Versatile)
Disc) and other recording media that allow random access are being used.

[0004] The use of the above-mentioned random-accessible recording medium enables recording of images such as television programs.
Various functions that cannot be realized with a conventional video tape have been added to a recording / reproducing apparatus for performing reproduction.

As an example of the above function, there is, for example, a chase reproduction function. The chase playback function is a function that enables the playback of a currently-recorded video in the middle of recording and the playback of another recorded video in the middle of recording, which was impossible with a conventional recording and playback apparatus.

In the chase reproduction function, when reproducing a recorded video already recorded while a video is being recorded, for example, the user performs the following operation. That is, the recorded video to be reproduced and the video being recorded are displayed side by side on the television screen, and the video to be reproduced (recorded video) is moved forward (corresponding to fast forward on a conventional video tape) and retracted (conventional video tape). After the desired playback position is determined by rewinding (corresponding to rewinding on a video tape), the recorded video is displayed from the playback position at the center of the television screen.

When the user wants to see the already recorded portion of the video being recorded, the user displays the head of the already recorded video and the video being recorded side by side, and selects the head video by selecting the head video. The recorded video is displayed in the center of the TV screen.

The above is a description of typical functions added by using a recording medium that can be randomly accessed, and an operation method corresponding to the functions.

By the way, although it is unavoidable due to the nature of the video tape, the display of the video information recorded on the video tape when the conventional video tape is used was insufficient.

[0010] For this reason, for example, Japanese Patent No. 3107063 discloses a technique for displaying information of a video recorded on a randomly accessible recording medium.

[0011] The technique described in Japanese Patent No. 3107063 discloses a technique in which a scheduled recording time of a video being recorded and a recorded time are displayed in a superimposed manner, and a pointer indicating a reproduction position is displayed on the display. This is a technique that allows a user to easily grasp a scheduled recording time, a recorded time, and a reproduction position.

[0012]

SUMMARY OF THE INVENTION As mentioned above,
Various functions have been added to the recording / reproducing apparatus because the recording media can respond to various function requests. However, with the addition of a large number of complicated functions, the user is forced to perform unprecedented operations, and in order to make full use of the additional functions, it is necessary to learn complicated operations. For example, when switching between a recording video and a recorded video, as described above, it is necessary to first display the recorded video and the recording video side by side, and select a desired video from the display. Naturally, when selecting a video desired to be reproduced from a plurality of recorded videos, it is necessary to display the plurality of recorded videos, and after selecting the recorded video, the video is reproduced, for example, from the middle of the video. If you go forward
The operation is complicated because a work such as retreat is required. Therefore, there is a demand for the development of an interface that can fully utilize the above functions and does not require the user to learn the complicated operation, that is, has an operability that is easy for the user.

Further, since the recording time of the conventional video tape is relatively short, it is necessary to replace the video tape, that is, the user judges the difference in the video based on the difference in the video tape. However, now that the replacement of recording media is becoming unnecessary with the increase in capacity of the recording media, a large number of videos can be recorded on one recording medium. Therefore 1
It is becoming necessary to manage images within one recording medium.

However, the above-mentioned patent No. 31070
According to the technology described in JP-A-63-63, it is possible for a user to easily grasp a scheduled recording time, a recorded time, and a reproduction position for one video, but grasp information of a plurality of videos recorded on one recording medium. It is impossible to do. In other words, information such as how many videos are recorded on the recording medium, how much remaining recording time is available, and which video occupies the recording medium and how much is easily provided. In addition, there is a problem that it cannot be easily understood. Further, only a display function of video information is provided, and no management of the video is disclosed at all.

In particular, since the recording capacity of the hard disk, DVD, and the like has been increasing at an accelerating rate in recent years, the recordable time of video has far exceeded that of the video tape. An increase is expected. For this reason, there is an urgent need to provide a technique for easily managing each recorded video in one recording medium.

Therefore, the present invention displays information recorded on a recording medium visually and intelligibly, and displays a sufficient information for the user by receiving the user's input using the display. It provides easy operability, and at the time of chase playback, it is possible to switch between the recorded video and the video being recorded without switching the screen, and it is also possible to switch the recorded video with a simple operation. An object of the present invention is to provide a recording and reproducing device.

[0017]

The present invention has the following means to achieve the above object.

That is, it is assumed that a recording / reproducing apparatus that records and reproduces a video using a medium that can be randomly accessed is used. Here, the quantitative display means provided in the recording / reproducing apparatus visually quantitatively displays the recording time of the recorded video recorded on the medium and the remaining recordable time, and the indicator control means controls the video being reproduced. At least one of the reproduction position in the quantitative display and the recording position in the quantitative display of the video being recorded.

Further, the indicator selection executing means selects at least one of the reproduction indicator, the recording indicator, and the quantitative display, which are display objects, and is selected as a predetermined command input by a user, for example. The user executes the predetermined processing based on the display object. Therefore, the user sees the quantitative display (scale) so that the number, the reproduction time, and the remaining recordable time of the images already recorded on the recording medium can be instantaneously visualized. You can know. In addition, it is possible to instantaneously select a desired playback video, playback position, and the like by enabling a user to visually directly input an instruction to a display object such as a scale (quantitative display), a playback indicator, and a recording indicator. This makes it possible to provide a user interface with higher operability.

The image display device further includes image display means for displaying an image recorded in the recorded video, and the image displayed by the image display means includes an image when the audio mode is switched in the recorded video and a scene change in the recorded video. There is a configuration in which an image at the time or an image of a preset scene in a recorded video is used.

In this configuration, it is possible to display a characteristic still image of each video. For this reason, it is possible to select a video position where the user is likely to be interested (hope to browse), and it is possible to enhance operability by the user.

Further, there is a configuration in which the end indicator control means displays the expected end position in the quantitative display of the video being recorded.

With this configuration, the user can instantly know information such as how far the recording has progressed, and how long the recording will be completed.

Further, there is a configuration in which a time interval between the recording position indicated by the recording indicator and the reproduction position indicated by the reproduction indicator is displayed, and a configuration in which the time interval is a time required for the reproduction indicator to catch up with the recording indicator.

With this configuration, the user can accurately grasp the time until the playback indicator reaches the recording indicator.

Further, there is a configuration in which the quantitative display means quantitatively displays the recorded video based on any of the reproduction time, the recording capacity, and the recording location, and a configuration in which the three types of quantitative display can be switched.

With this configuration, the user can select a display suitable for the intended operation, that is, it can provide information necessary for the user's operation.

Further, in addition to the playback indicator,
A jump indicator control means for displaying a jump indicator indicating that a predetermined position of the recorded video is selected on the quantitative display, the display object being a processing object of the indicator selection execution means, There is a configuration to do.

In this configuration, the video at the position indicated by the jump indicator is displayed at a position different from the display position corresponding to the reproduction indicator, so that the user can select a different video while keeping the video being reproduced. It can be carried out.

Further, there is a configuration that moves in conjunction with a reproduction indicator or a recording indicator.

With this configuration, when the user wants to see the same scene again, the user can immediately reproduce the target video by selecting the jump indicator.

Embodiments of the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention.
It should be noted that the following embodiments are examples embodying the present invention, and do not limit the technical scope of the present invention.

[Embodiment 1] First, an outline of a recording / reproducing apparatus according to Embodiment 1 will be described with reference to FIGS. FIG. 4 shows an example of the remote controller.

The recording / reproducing apparatus 101 shown in FIG. 1 includes a system control unit 102, a recording control unit 103, a reproduction control unit 104, a recording medium 105, an input control unit 106,
It comprises a UI control means 107, an AV output control means 108, and a reception means 109. Incidentally, the recording / reproducing apparatus 101
Specifically refers to a digital video recorder, a DVD recorder, or the like, and the recording medium 105 is a hard disk or a D
It is a randomly accessible medium such as a VD (DVD-RAM, DVD-RW, etc.) and is not necessarily required to be removable. The receiving means 109 is a tuner capable of receiving a program broadcast or the like, and the program broadcast is provided by a cable broadcast, a wireless broadcast, or the like. However, it is not always necessary to receive the program broadcast. For example, a video recorded by a home digital video or the like may be stored (recorded) in the recording medium 105. Also, the display means 110
Is a display section of a television or a remote controller (remote controller) 401, and does not particularly limit a display method. Here, it is referred to as a video including a program broadcast and other moving images.

Each unit stored in the recording / reproducing apparatus 101 is provided as hardware or software.

Next, the basic input / output operation of the recording / reproducing apparatus 101 will be described. An instruction from the user to the recording / reproducing apparatus 101 is first received by the input control means 106 and transmitted to the system control means 102. Here, for example, if the instruction from the user is an instruction to record a program broadcast (video), the program broadcast (video) selected by the user
Is received by the receiving means 109 and transmitted to the system control means 102 as an image. Next, the system control unit 102 transmits the video to the recording control unit 103, and the video recording control unit 103 transmits the video to the recording medium 105.
To record. As described above, a predetermined video is recorded (recorded) on the recording medium 105. The user's input is performed by, for example, the remote controller 401.

Next, when the user issues a video reproduction instruction to the input control means 106 using the remote controller 401 or the like, the reproduction instruction is transmitted to the system control means 102 and further transmitted to the reproduction control means 104. Is done. Subsequently, the reproduction control unit 104 transmits the information of the video recorded on the recording medium 105 to the system control unit 102. Here, the video information is information used for specifying a video, such as a program name, a recording date and time, and a reproduction time.

Upon receiving the video information, the system control means 102 transmits the video information to the AV output control means 108.
, And the AV output control means 108
And converts the information of the video to a display unit 1
Send to 10.

When the display means 110 receives the image information, the display means 110 transmits the image information to the user by displaying it on a display such as a cathode ray tube or the display unit 404 of the remote controller 401.

Next, when the user confirms the information of the video and selects a desired video using the remote controller 401, the selected information is reproduced and controlled through the input control means 106 and the system control means 102. Transmitted to the means 104. When the reproduction control means 104 receives the selection information, the video corresponding to the selection information is displayed on the recording medium 1.
05, and transmits it to the AV output control means 108 via the system control means 102. The AV output control means 108 outputs the received video to the display means 110 to display the video selected by the user on the display.

The above is the basic input / output operation of the recording / reproducing apparatus 101. In the first embodiment, the GUI control means 107 further performs various controls for user input.

Next, the processing performed by the GUI control means 107 will be described in detail with reference to FIGS. 1, 2, 3, 4, 5, and 9. FIG. 2 is an example of a display object displayed by the GUI control unit 107 on, for example, the display unit 110 (including the display unit 404 of the remote controller 401). FIG. 3 is a diagram illustrating a case where the display object is displayed on a display. It is an image figure. FIG. 5 is a flowchart showing processing in the GUI control means.

The following is a method of selecting and reproducing a video at the time of video reproduction.

First, the user presses, for example, a predetermined button of the remote controller 401 shown in FIG. 4, for example, the reproduction 402, to display the content (information) of the video recorded on the recording medium 105. The request is transmitted to the input control means 106. The content display request is received by the system control means 102 via the input control means 106, and the system control means 102 transmits the content display request to the GUI control means 107.

Next, when the quantitative display means 111 constituting the GUI control means 107 receives the contents display request, the system control means 102 and the reproduction control means 10
The recording information is read from the recording medium 105 via the recording medium 4 (FIG. 5: S501). Here, the recording information includes the number of recorded videos already recorded, the recording time of each recorded video, the total recordable time of the medium, and the like. Subsequently, the quantitative display means 111 calculates (video recording time / total recordable time of the medium) based on the recording information (FIG. 5: S50).
2). Specifically, for example, in the case of a medium in which the total recordable time is 5 hours, and 0.2 in the case where the video recording time is 1 hour. The calculated numerical value is the length of the scale of the recorded video when the overall scale 201 in FIG. The actual length (ratio) of the entire scale 201 on the display varies depending on the display position and the like. The scale is a visual quantitative display of the recording time of each video and the remaining recordable time of the media.For example, using the display area of each scale, the size, capacity, time, etc. of the scale can be determined. It is something to express. Specifically, for example, it is a graph display.

When the ratio of the corresponding video to the entire scale 201 is calculated, it is then determined whether or not the above-described calculation has been performed on all the videos. On the other hand, the above calculation process is repeated (FIG. 5: S503 No. to S502).

When the above calculation is performed for all the recorded images, then (unrecorded time / total recordable time of the medium)
Is calculated. This processing determines the length of the scale of the remaining recordable time on the medium 105 (FIG. 5: S503Yes to S504). However, the unrecorded time may be different depending on, for example, a video recording mode, that is, a setting such as high-quality recording or low-quality recording. In this case, the currently set video recording mode,
Alternatively, it can be set arbitrarily such as the same recording mode as the previously reproduced video. As described later, when performing the above-described quantitative display processing during recording, it is desirable to calculate the unrecorded time using the currently recorded recording mode.

When the length (ratio) of each video and the unrecorded time with respect to the entire scale 201 is determined, the calculated scale of each video and the scale of the unrecorded time are created (FIG. 5: S505 to S506). ).

The created scale is displayed at a predetermined place on the display means 110 via the system control means 102 and the AV output control means 108. The scale can be displayed by using a different pattern, color, or the like for each video, for example, so that the user can easily distinguish each video.

FIG. 2 shows an example of the above scale. 2 is a case where the storage capacity of the recording medium 105 can record a video of 5 hours as standard, for example.
Is scaled based on the recording time (reproduction time) of the video. That is, assuming that one rectangular block 207 is 20 minutes, the image 2
02 is 60 minutes, video 203 is 40 minutes, video 204 is 80
The video 205 has a playback time of 40 minutes. However, when the recording modes described above are different, for example, when the video 203 is recorded using twice the capacity of the video 204, for example (normally, the video 203 is more beautiful than the video 204), the actual recording medium 105 Within each video 203,2
04 occupies the same capacity.

In addition to the scale of each video, the remaining recordable time 206 is scaled and displayed. Here, assuming that all images are recorded using the same recording mode, the remaining recordable time 206 is composed of four rectangular blocks, that is, 80 minutes.

As described above, since the scale of each video is scaled using the playback time, the user can instantly and visually know the playback time of each video by looking at the scale. Note that the remaining recordable time 206 is also displayed, but as described above, the remote control 4
When a command not related to video recording is input, such as when the user presses 02, it is not always necessary to display the remaining recordable time 206.

Next, after the quantitative display means 111 displays the scale via the AV output control means 108, the reproduction indicator control means 112 constituting the indicator control means 120 controls the previously reproduced video on the indicator. The reproduction indicator 208 is displayed at the position (FIG. 5: S507). The display of the playback indicator 208 is the same as the scale, and the system control means 102 and A
This is performed on the display unit 110 via the V output control unit 108. It is assumed that the position of the previously reproduced video is stored in a storage area (not shown) of the GUI control unit 107. However, if there is no record of the position of the video reproduced last time, for example, the first video (the video with the oldest recording) 202
The reproduction indicator 208 is displayed at the top of the list (FIG. 5: S507).

Next, the reproduction indicator control means 11
After the playback indicator 208 is displayed in Step 2, the GUI
The image display means 113 constituting the control means 107 displays the still image cursors 210 to 218 at predetermined positions on the scale corresponding to the images 202 to 205 (FIG. 5: S508 to S509). The still image cursor 210
Reference numeral 218 is displayed on the display unit 110 via the system control unit 102 and the AV output control unit 108, similarly to the scale and playback indicator. The display positions of the still image cursors 210 to 218 (indicating the positions in the respective videos 202 to 205) are determined by the image display means 113. The details of the determination will be described later.

Next, the image display means 113 displays each video (still picture: thumbnail) 220 to 228 corresponding to each of the still picture cursors 210 to 218 via the system control means 102 and the reproduction control means 104. Read from the recording medium 105.

The read still images 220 to 228 are displayed at positions corresponding to the still image cursors 210 to 218, respectively (FIG. 5: S510). Note that, in FIG. 2, the still image cursors 210 to 218 respectively correspond to the still image 2
20 to 228. Further, in FIG. 2, the still images are arranged side by side, but they may be displayed immediately beside the corresponding still image cursors. Further, a still image is displayed above the scale display, as in a predetermined area (child screen) 903 of the display 301 in FIG. 9, and a still image in the predetermined area 903 is displayed by selecting a still image cursor 904. The cursor may be switched to the one corresponding to the cursor 904. By doing so, it becomes possible to provide the display object to the user without the display object pressing on the area 302 of the reproduced video.

As described above, the reproduction indicator is displayed at the scale and the corresponding position of the scale, and the still image cursor and the still image are displayed. As a result, the user can instantaneously grasp the number of videos already recorded on the recording medium, the reproduction time, the remaining recordable time, and the position of the previously reproduced video, visually (intuitively). In addition, since the still image cursor and the still image are displayed at the corresponding positions of each video (scale), the user can easily know what kind of scene the predetermined position of each video is. Furthermore, the indicator selection execution means described later allows the user to easily select and play back the continuation of the previously played back video or the position displayed in the still image.

Next, a still image cursor 210 of a recorded image (images 202 to 205) is displayed by the image display means 113.
The method for determining the 218 position will be described (FIG. 5: S508).
Processing).

In FIG. 2, for example, the position of the still image cursor 210 in the video 202 corresponds to the still image 220, and the still image cursor 212 corresponds to the still image 222 as described above. Here, the still image cursor 210
In determining the positions of to 212, it is preferable that the image is a still image capturing the characteristics of the video 202. Therefore, the image display means 113 determines the position as follows.

First, one is a switching position of the audio mode. That is, conventionally, for example, CM (commercial)
In some cases, stereo broadcasting is used as an audio mode, and in video (program broadcasting), monaural broadcasting or bilingual broadcasting is used. In such a case, the recording medium 1
Since the difference between the above audio modes is also recorded in the area 05, the location where the audio mode switches (the location in the video) is used as a boundary,
The position immediately before or immediately after that is determined as the still image cursor position.

There is also a method of recognizing a scene change of the video 202. For example, in the technology disclosed in Japanese Patent Application No. 9-77285, the image is extracted by performing image classification information detection processing. That is, a total sum S (Y) of the luminance values Y of an image of a certain frame is calculated, a correlation C with the immediately preceding frame is calculated, and a scene change is determined by comparing the correlation C with a predetermined threshold. How to Since the method of recognizing a scene change is not directly related to the gist of the present invention, the details are omitted.

Further, a position preset by the user may be used as the still image cursor position. For example, when the user watches the video 202 once, the information is transmitted to the image display unit 113 by pressing a predetermined button of the remote control, for example, a still image 403 at a location of the favorite video,
The position of the video (scene) is stored.

As described above, by effectively selecting the position of the still image cursor, it becomes possible to display a characteristic still image of the video. For this reason, it is possible to select a video position where the user is likely to be interested (desired to browse), thereby improving the operability by the user. The above three still image position determination methods may be selected by the user to select which method, or the recording / reproducing apparatus 101 may automatically select an appropriate method.

Next, the scale, reproduction indicator,
FIG. 3 shows an example in which display objects such as a still image cursor and a still image are displayed on the display 301 (an example of the display unit 110). On the left end of the display 301, each display object shown in FIG. 2 is displayed as a stacked graph, for example, on a scale. Of course, it is not necessary to be the left end of the display, and the right end or the above scale may be displayed at the lower end as a horizontal stacked graph, or an independent window may be displayed and displayed in the window. Also, instead of the stacked graph, a pie chart or the like may be used.

When each of the display objects is displayed,
The indicator selection executing means 116 allows the user to input to the display object. That is, the user can use the remote control 401 or
By touching the panel of the first display unit 404, etc.,
An instruction is transmitted to the input control means 106. The instruction is mainly performed using the cursor keys 405 of the remote controller 401. First, it is assumed that, for example, the reproduction indicator 208 of the display object shown in FIG. 2 has focus. The focus indicates a state where the display object to be operated by the user is selected.

When, for example, the “right” of the cursor key 405 is pressed while the reproduction indicator 208 is in focus, a signal indicating the “right” is input to the input control unit 106.
And GUI control means 1 via the system control means 102
07 is transmitted to the indicator selection executing means 116.

When the signal indicating “right” is recognized by the indicator selection executing means 116, the indicator selection executing means 116 internally moves the focus to the still image cursor 210. The selection of the display object to which the focus is to be moved is determined by, for example, managing the position (coordinates) of each display object on the screen by the indicator selection execution unit 116. That is, here, the focus moves to the still image cursor 210 located near the right of the reproduction indicator 208.

At this time, in order to manage the display object to be focused, the indicator selection executing means 116 controls the indicator selection executing means 11.
For example, in the selection execution table shown in FIG.
The still image 210 (802) in the focus 803 is selected. The selection is for internally managing the display object that currently has focus.

Also, in order to show the user that the still image cursor 210 has focus on the display, the system control means 102 and the AV control unit 102 update the display to indicate that the still image cursor 210 is selected. An instruction is given to the display means 110 via the output control means 108. Thus, the still image cursor 210 is selected on the display. The still image cursor 210
Is selected, for example, on the right side of the display shown in FIG.
In the still image 2 corresponding to the still image cursor 210
20 may be displayed.

Next, by further pressing "down" in this state, the still image cursor 21 is displayed internally and on the display.
The focus moves sequentially to 1, 212, and 213. The moving process is the same as described above.

Subsequently, the still image cursors 210 to 21
It is assumed that the user presses the playback 402 of the remote controller 401 in a state where any one of the buttons 8 (here, the still image cursor 210) has focus. In this case, the indicator selection execution unit 116 sets the area 805 based on the currently selected focus position (here, the still image 210 (802)) and the reproduction 804 corresponding to the pressed “reproduction 402”. The stored (described) processing content is transmitted to the system control unit 102. Here, for example, the “playback from the position of the still image 210” process is performed.

When the above-mentioned processing content is received by the system control means 102, the video at the position corresponding to the focused still image cursor is read out from the recording medium 105 via the reproduction control means 104, and It is displayed on the display unit 110 via the AV output control unit 108, that is, reproduced.

In addition, processing is performed based on each display object 806 selected at the focus position 803 of the selection execution table 801 and an item 807 corresponding to an input signal input via the input control means 106 by a remote controller or the like. The processing described in the content 808 is executed in the same manner as the other processing.

As for the movement of the focus, when the “down” of the cursor key 405 is pressed while the reproduction indicator 208 is in focus, for example, the position of the reproduction indicator 208 is moved to the head position 209 of the next video 203. You may make it. Further, by continuing to press “down” of the remote controller 401, the playback indicator 208 may be gradually moved downward, that is, the playback position desired by the user may be finely adjusted.

In the state where the reproduction indicator 208 is selected, as described above, when the user presses the reproduction 402, the video corresponding to the position is reproduced.
Note that the reproduction indicator control means 112 moves the reproduction indicator 208 to a position indicating a reproduction position in the scale at any time with the reproduction of the video. By this movement, the user can easily recognize the position of the currently reproduced video in the entire video.

A number is displayed on each of the still images 220 to 228, and the number keys 407 of the remote controller 401 are displayed.
, A still image may be selected by inputting a number corresponding to each of the above-described still images, or may be reproduced from the position of the still image.

As described above, it is possible to visually and directly input an instruction to the scale, the reproduction indicator, each still image cursor, and the still image through the indicator selection executing means, and thereby a desired reproduced image can be obtained. The user can instantaneously select a reproduction position and the like, and can provide a user interface with higher operability. This is an environment in which the input is difficult and the function of each button is difficult to judge because there are many buttons, that is, as a means for solving the problem of the recording / reproducing apparatus in which an environment using a remote controller with poor input is mainly used. , Very effective.

By transmitting the video signal from the AV output control means 108 to the remote control 401, the user can operate the video while viewing the display object 410 displayed on the display unit 404 of the remote control 401 in FIG. Since only the video can be displayed on the display means 110, the display area can be widened. In addition, by adopting a touch panel method for the display unit 404 of the remote controller 401, the focus can be easily moved, and a user interface with higher operability can be provided.

Further, for example, a sub-display which is a display device different from the display is provided, and the AV output control means 108 is configured to send the video signal of the display object to the sub-display.
It is possible to display only the reproduced video on the display.

Furthermore, in the first embodiment, the display is performed by the quantitative display means based on the video recording time (reproduction time). However, if necessary, the display may be scaled based on the recording capacity.

That is, the quantitative display means 111 obtains the data size of each video recorded on the recording medium 105, or obtains the data size of each video based on the product of the recording mode (for example, 1 ×, 2 ×, etc.) and the recording time. The recording capacity is calculated. By creating a scale based on the recording capacity, for example, if it is necessary to secure a certain recording capacity,
Since the ratio of each video to the recording medium can be grasped at a glance, the user can provide easy-to-understand information when determining the video to be deleted according to the recording capacity.

Further, by faithfully displaying the recording location of the video on the recording medium in a scale, it is possible to provide the user with information on the timing for eliminating the fragmentation of the recording medium. That is, for example, FIG. 10 shows an example in which the quantitative display displayed by the recording / reproducing apparatus is changed to a display using a recording location.

In this case, although no fragmentation has occurred in the images 202 and 203, the image 204 in FIG.
4-2 and 204-3 are seen to be fragmented. Similarly, the image 205 in FIG. 2 is fragmented into the images 205-1 and 205-2 in FIG.
It can be seen that 01 to 1003 are divided.

Incidentally, the quantitative display means 111 may be configured to be able to switch between scaling using a recording time, scaling using a recording capacity, and scaling using a recording location in response to a user's instruction and displaying the same. By enabling the switching, the user can obtain a display according to the purpose.

[Second Embodiment] In the first embodiment,
The processing at the time of reproduction by the recording / reproducing apparatus 101 has been mainly described. In the second embodiment, the processing at the time of recording will be mainly described. Note that the transfer of signals inside the recording / reproducing apparatus 101 is basically the same as in the first embodiment, so only necessary parts will be described.

First, when the user wants to record a predetermined video (program broadcast), the user operates the remote controller 401 to select a video (program broadcast) to be received by the receiving means 109 (FIG. 7: S701). This is an operation performed on a tuner performed on a conventional television, so that the details are omitted.

Subsequently, the user presses, for example, a menu 409 on the remote controller 401 to display a plurality of recording modes, and selects a desired recording mode from among the plurality of recording modes (FIG. 7: S702). The recording mode corresponds to the recording indicator control means 1 constituting the indicator control means 120.
14 and stored. In addition, the user can use the remote control 4
01, the recording instruction of the currently selected video (program broadcast) is pressed by the recording / reproducing apparatus 10.
1 (FIG. 7: S703). The recording instruction is G
The scale 201 received by the UI control unit 107 and described in the first embodiment is displayed on the display unit 110 by the quantitative display unit 111 (FIG. 7: S704).

Here, the scale 201 shown in FIG.
The remaining recordable time 206 is a display calculated again in the recording mode selected by the user, and the remaining recordable time 206 described with reference to FIG. 2 is 80 minutes. Assuming that the user has selected the triple mode in 2, recording for 240 minutes is possible.

In the case of recording, the reproduction indicator 20
8, still image cursors 210 to 218, still images 220 to 2
It is not always necessary to display 28 and the like. Further, the scales corresponding to the other videos 202 to 205 need not always be displayed.

FIG. 6A shows the remaining recordable time 206 in FIG. 2 corresponding to the selected recording mode.
An example of the display when 40 minutes is set is shown. FIG. 6 (a)
In the state (1), the scale 601 has not been recorded yet, so that all rectangular blocks have not been recorded.

Next, the scale 601 is connected to the quantitative display means 11.
When displayed by 1, the recording indicator control means 114 subsequently displays the recording indicator 602. The recording indicator 602 is displayed at the head of the scale 601. Also, the recording indicator control means 114
As in the case of the reproduction indicator 208, the recording indicator 602 is moved below the scale 601 as the recording proceeds, corresponding to the time of the already recorded video.

Subsequently, when the recording indicator 602 is displayed, the end indicator control means 115 displays the end indicator 603 at a position corresponding to the end time of the video (program broadcast) being recorded (FIG. 7: S706). . Here, the end indicator 603 indicates, for example, a case where the user has reserved the recording time in advance, a case where information on the broadcast end time can be obtained from a video (program broadcast), or the case where the recording / reproducing apparatus 101 is an EPG (Electronic Program Guide) This is displayed when the end time can be obtained from ()). FIG.
(A) shows that each rectangular block is 20 minutes long.
This is a display at the time of starting to record an 80-minute video (program broadcast).

Next, as the recording of the video (program broadcast) progresses, as shown in FIG.
Moves downward, and a pattern or color indicating that the video (program broadcast) has been recorded is displayed in the rectangular block in which the video (program broadcast) has already been recorded (FIG. 7: S707). Update of the display,
This is performed by the recording indicator control means 114 and the quantitative display means 111 as appropriate.

When the recording indicator 602 coincides with the end indicator 603, ie, the video (program broadcast)
Is completed, recording of the video (program broadcast) ends (FIG. 7: S708). It should be noted that the recording indicator 602 may be turned off when the recording is completed.

As described above, by visually displaying the recording state of the video (program broadcast) using the scale 601, the recording indicator, and the end indicator, the user can determine how much the recording is progressing, and furthermore, It is possible to instantly know information such as how long the recording will end. In addition, by displaying the end indicator, it is possible to easily know information about how much remaining recording time remains.

In order to display the time until the recording is completed in more detail, the recording indicator control means 114
However, for example, as shown by a gauge 604 in FIG. 6B, a time interval between the end indicator 603 and the recording indicator 604 may be displayed together with a numerical value.

[Third Embodiment] Next, in the third embodiment, a description will be given of a process at the time of chase reproduction peculiar to a case where a recording medium is randomly accessible.

For example, it is conceivable that the user is recording a baseball program (video) and the recording is progressing partway.
In such a case, chase reproduction is used when the user wants to watch the baseball program from the beginning. That is,
In the state where the baseball program (video) is recorded in the recording / playback apparatus 101, the user plays back the baseball program from the beginning. However, in normal speed reproduction, it is unlikely that the baseball broadcast will catch up with the record before the end. Here, “double speed playback” and “3
By using a reproduction method such as "double speed reproduction", it is possible to catch up with the currently recorded baseball program (video).

The chase reproduction can be performed, for example, by simply selecting the head of the scale in the quantitative display shown in FIG. 6C and starting reproduction as described in the first embodiment. . The reproduction method such as the “double speed reproduction” can be selected by pressing the menu 409 of the remote controller 401 or the like.

When the chase reproduction is started in the reproduction processing, the reproduction indicator control means 112 displays the reproduction indicator 605 at the head of the scale 601, as described in the first embodiment, and as the reproduction proceeds, the reproduction indicator 605 Move the indicator down.

When the reproduction indicator 605 catches up with the recording indicator 602, as shown in FIG.
The reproduction indicator 605 disappears and only the recording indicator 602 and the end indicator 603 are provided. In this state, the video (program broadcast) being recorded is displayed on the display unit 110.

As described above, the scale 601, the recording indicator 602, and the reproduction indicator 605 are displayed on the display unit 1.
Displayed on the screen 10, the user can visually grasp all processes of the recording / reproducing apparatus 101 for the current recording medium.

Further, at the time of chase reproduction, the reproduction indicator control means 112 controls the recording indicator 602
Gauge 60 that connects to the playback indicator 605
6 is displayed, and the time until the playback indicator 605 catches up with the recording indicator 602 is displayed. The time can be calculated by the following (Equation 1) by using the reproduction speed, the position of each indicator from the start of recording (time from the start of recording), and the like.

(Recording Indicator Position-Playback Indicator Position)
(Reproduction speed-recording speed) Expression 1 Here, the following gauge 606 particularly has the following effects.

That is, at the time of the chase reproduction, unlike the gauge 604 described above, the number of rectangular blocks on the scale does not indicate the time to catch up with the recording indicator. Specifically, for example, in the case shown in FIG.
The value indicated by the rectangular block between the playback indicator 605 and the recording indicator 602 is 80 minutes. However, for example, if playback is performed at 3x speed,
It takes 40 minutes after the playback indicator 605 catches up with the recording indicator 602. That is, the scale
At the time of chase reproduction, information on the time until the reproduction indicator 605 catches up with the recording indicator 602 is not displayed. Therefore, the user needs to calculate using the reproduction speed, the time from the start of recording, and the like to know the time to catch up with the currently broadcast baseball program (video). However, since the calculation is not as easy as that required by mental arithmetic, it can actually be recognized only with an accuracy of “about ○ minutes”. The display of the chase gauge 606 enables the user to accurately grasp the time until the reproduction indicator 605 reaches the recording indicator 602.

It is also possible to make the reproduction control means 104 calculate (reversely calculate) an appropriate reproduction speed and perform reproduction by making a setting such as "catch up after one hour" from the remote controller 401.

[Fourth Embodiment] Next, in a fourth embodiment, processing of a jump indicator for facilitating selection of a predetermined video will be described.

FIG. 9 shows an example in which an area 302 for displaying a reproduced image such as a program on the display 301 and each display object 901 are displayed. Here, the display object 901 includes the jump indicator 9 in addition to the display objects described in the first to third embodiments.
02 is displayed.

The jump indicator 902 is shown in FIG.
Is controlled by the jump indicator control means 117 shown in FIG. The display method and the selection method of the jump indicator are the same as those of the other indicators in the first to third embodiments, and a description thereof will be omitted. Here, only a process specific to the jump indicator 902 will be described.

The jump indicator 902 has a function similar to that of the playback indicator 208. However, while the playback indicator 208 indicates the position of the video currently being played, the jump indicator 902
Can be operated independently of the video currently being reproduced. That is, for example, when the user moves the playback indicator 208 via the remote control, the area 302 also displays the video at the position indicated by the playback indicator 208. On the other hand, moving the jump indicator 902 does not affect the image displayed in the area 302.

Therefore, when the video currently being reproduced (recorded) is displayed in the area 302, the display is not changed and, for example, a video or a video that the user wants to view from among a plurality of other recorded videos. When the user wants to select a desired scene, the jump indicator is used.

Hereinafter, the processing of the jump indicator control means 117 will be described. It is assumed that the jump indicator 902 is displayed on the display object 901 in advance.

First, the user focuses on the jump indicator 902 by using, for example, a cursor key 405 of a remote controller. Subsequently, when the jump indicator 902 is moved using the cursor key 405, an image corresponding to the moved position is read from the recording medium 105 via the reproduction control means 104, and the system control means 102, the AV output control It is output to the display means 110 via the means 108. However, the video corresponding to the position of the jump indicator 902 is a predetermined area (small screen) 9 on the display 301 as a moving image or a still image.
03 is displayed. For this reason, the area 302 displays the video currently being reproduced (recorded).

Next, when the user wants to reproduce from the place corresponding to the place where the jump indicator 902 is located, the jump indicator 902
With the focus on
Press 2.

Pressing of the reproduction 402 is performed by the input control means 1
06, transmitted to the indicator selection execution means 107 via the system control means 102, and the indicator selection execution means 107 obtains the current position of the jump indicator from the jump indicator control means 117.

[0116] Having obtained the position of the jump indicator, the indicator selection execution means 116 instructs the system control means 102 to reproduce the corresponding video from the position.
And the playback indicator control means 11
2 is notified to change the display position of the reproduction indicator to the acquired position.

When the system control means 102 receives the above-mentioned notification of reproduction, the corresponding video is obtained from the recording medium via the reproduction control means 104 and displayed in the area 302 on the display 301.

The reproduction indicator control means 11
2 changes the display position of the playback indicator to the position obtained above.

As described above, by providing the jump indicator and displaying the video at the position indicated by the jump indicator at a position different from the display position corresponding to the playback indicator, the user can leave the video being played as it is. Thus, different images can be selected.

Further, the jump indicator may be automatically moved in conjunction with the reproduction indicator or the recording indicator.

That is, the jump indicator control means 117 acquires the position information of each indicator from the reproduction indicator or the recording indicator as needed, and moves the jump indicator to the vicinity of each indicator.
The vicinity of the indicator is, for example, a position corresponding to several seconds before the currently reproduced video.

Thus, for example, when the user wants to see the same scene again while playing a video such as a sports broadcast, the user can select the jump indicator to immediately play the target video. Becomes possible. The position of the linked jump indicator may be arbitrarily determined by the user.

As described above, it is possible to input an instruction to the jump indicator in addition to the playback indicator and the recording indicator, thereby enabling the present playback (recording).
It is possible to instantaneously select a desired reproduced video and a reproduction position without affecting the display inside.

[0124]

Since the scale of each video is scaled using the playback time, the user can instantly and visually know the playback time of each video by looking at the scale.

Furthermore, by enabling the user to visually directly input an instruction to a display object such as a scale, a playback indicator, a recording indicator, a still image, a jump indicator, etc., a desired playback video and playback position can be selected. And the like can be performed instantaneously, and a user interface with higher operability can be provided.

Further, the user can instantaneously grasp the number, the reproduction time, the remaining recordable time, and the position of the previously reproduced image on the recording medium instantaneously. is there.

Further, since the still image cursor and the still image are displayed at the corresponding positions of each video (scale), the user can easily know what kind of scene the predetermined position of each video is. .

Further, by effectively selecting the position of the still image cursor, it becomes possible to display a characteristic still image of the video. For this reason, it is possible to select a video position where the user is likely to be interested (desired to browse), thereby improving the operability by the user.
