Abstract

PROBLEM TO BE SOLVED: To reproduce a crucial moment with a simple operation. SOLUTION: When contents are recorded in a recording part (YES in S21) in the case a time shift button is pressed down during contents reproduction (step S20), an input operation deciding part decides the time when a user presses down the time shift button of an inputting part (S24). Even though slow contents reproduction is carried out in the case the time when the time shift button is pressed down is less than fixed time ('below fixed time' in S24), whether or not video recording data exist in the recorded part is decided before that (S27). When the video data are recorded in the recorded part (existence in S27), slow reproduction is started from the point of time when the time shift button is pressed down (S30), when the slow reproduction is performed until slow reproduction end time, slow reproduction returns to slow reproduction start time (S31), and slow reproduction is repeated (NO in S31).

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 for reproducing content information distributed via a wired or wireless communication network, and more particularly to a recording / reproducing apparatus capable of reproducing content with a delay. .

[0002]

2. Description of the Related Art When watching a broadcasted program such as a TV program, the user may miss a program for a short time by missing his / her seat for a short time. In such a case, there is a method of recording a program with a VTR (Video Tape Recorder) or the like before leaving the seat. However, in the above method, if the user wants to watch a program from a missed portion, it is necessary to reproduce the recorded program from the missed portion after the broadcast of the program ends. For this reason, there is a problem that the content of the program is interrupted on the way.

In order to solve such a problem, a VTR
Instead, a hard disk recording / playback device that can be accessed randomly is gradually appearing. By using the hard disk recording / playback device, even if you miss a definitive scene in a sports program or want to play back (replay) the current scene again, you can continue to record from a desired position. It is possible to play.

Japanese Patent Laid-Open Publication No. Hei 7-336630 discloses that random access is possible as described above,
There has been proposed a recording / reproducing apparatus capable of reproducing from an arbitrary position between a present time and a predetermined time before. The recording / reproducing apparatus includes at least a writable storage medium that is randomly accessible and writable, a moving image / audio input unit that inputs a moving image or audio, a data writing control unit that writes data to the storage medium, and a storage medium. A data read control unit for reading data, a moving image / audio output unit for outputting a moving image or sound, a recording instruction unit for instructing start or end of recording, a reproduction instruction unit for instructing start or end of reproduction, and recording A reproduction position control unit for specifying an arbitrary position from the start time to the present time, and an overwrite control for recording moving image or audio data for a certain period of time by overwriting (overwriting) in order from the oldest data on the storage medium. And parts.

With such a configuration, only moving image or audio data is recorded on the storage medium for a certain period of time. For this reason, data can be reproduced (replayed) from a missed scene or a missed point, or from a scene you want to see or hear again without worrying about the capacity of the storage medium without increasing the data. it can.

For example, when the goal of a favorite soccer player is determined and the user wants to see the scene again, the pause button is pressed to stop the scene, and the rewind button is pressed to return to the scene before the shot, and temporarily stopped. It is possible to replay the goal scene by releasing the stop. As described above, since the storage medium is a storage medium that can be accessed at random, it is possible to find a desired video while instantly comparing the video with the video.

[0007] When the scene is to be viewed many times, a bookmark is added to the scene before shooting, and when the reproduction of the scene is completed, the bookmark button is pressed to return to the scene before shooting and reproduce the scene. You can see the goal scene again.

Further, if it is desired to include the performance of the player after the goal scene, the player may perform the playback or fast-forward once, check the position where the performance ends, and then press the bookmark button. You will be able to see the performance.

As described above, in the recording / reproducing apparatus, when temporarily leaving the seat while watching a program, the pause button is pressed to stop the video, and when returning to the seat, the pause button is released. This enables viewing from the subsequent scene. In addition, by using the bookmark function, the user can check a favorite scene during viewing and select a bookmark when he / she wants to see the scene.
The recorded video can be played back from the bookmarked scene. In the recording / reproducing apparatus, such a time shift function can be easily realized.

[0010]

However, even when the video is reproduced from the paused scene using the time shift function, the content of the program is often interrupted shortly before. . In such a case, it is necessary for the user to perform a rewind operation and perform reproduction from the rewind position.

In the recording / reproducing apparatus disclosed in JP-A-7-336630, a replay from a slightly earlier scene is possible. However, if the replay button is not pressed after waiting for the end of the scene to be replayed, for example, In some cases, it is not possible to completely replay a soccer goal scene or the like.

Further, if the pause button is pressed after the end of the goal scene, as if only the performance after the end of the soccer goal scene is to be repeated, the goal scene is replayed again. Therefore, in order to repeatedly view only the performance, complicated processing such as fast forward, reproduction, and rewinding is required.

By using the bookmark function, it is possible to return to the checked scene. However, although the bookmark is effective for the same program, the recording / reproducing apparatus watches and listens to the program being broadcast. Therefore, by changing the channel, the program being recorded is also changed. For this reason, it is not very effective for a user to check a bookmark in a recording / reproducing apparatus as disclosed in Japanese Patent Application Laid-Open No. 7-336630. Also, if a plurality of bookmarks are attached too much, it is difficult for the user to check which scene the bookmark has been checked while checking.

The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide a recording / reproducing apparatus capable of reproducing a crucial moment by a simple operation.

Another object of the present invention is to provide a recording / reproducing apparatus capable of preventing the number of checked bookmarks from being too large to be lost.

[0016]

According to an aspect of the present invention, there is provided a recording / reproducing apparatus which records a content continuously distributed via a wired or wireless network for a predetermined time in order from the latest content. A content playback unit for playing back the content, an input unit used by the user to instruct the slow playback of the content, and a recording unit and the input unit are connected to each other; Slow playback means for slow playback of the content for a certain period of time before and after the reception.

If slow reproduction is instructed during the reproduction of the content, the content before and after the slow reproduction is reproduced. For this reason, for example, when an image such as a decisive moment is displayed while the image is being viewed, it is possible to slowly reproduce the images before and after the scene with one button.

Preferably, the slow reproduction means repeats the slow reproduction of the content, and the recording / reproducing apparatus further displays the start time position, the end time position and the reproduction time position of the slow reproduction at the time of the slow reproduction of the content. And a change means for changing the start time position or the end time position of slow reproduction.

By changing the start time position and the end time position of the content, for example, a crucial moment of a video can be reproduced in slow motion.

More preferably, the recording / reproducing apparatus further includes: a content storage unit for storing the content; a content storage instruction unit used by a user to instruct the storage of the slow-reproduced content; a recording unit; Unit and content storage instruction means,
A content writing unit that writes the content currently being slow-reproduced from the recording unit to the content storage unit. For example, a critical moment of a video can be stored and can be reproduced many times later.

[0021] More preferably, the recording / reproducing apparatus is further connected to the input section, and stores a time point at which the user instructs slow reproduction of the content as a bookmark, and a slow reproduction instruction bookmark storage means, and stores the slow reproduction instruction bookmark. Means for playing back the content from the selected bookmark position, and a slow playback instruction when connected to the bookmark storage means and changing the channel of the content to be distributed. First bookmark erasing means for erasing the bookmark stored in the bookmark storage means.

Each time a user instructs slow reproduction of a content, a bookmark is automatically added. Therefore, there is no need to provide a button for attaching a bookmark, and it is possible to prevent the user from taking time to perform the operation. Also, when the channel is changed, the previous bookmark is automatically deleted. For this reason, it is possible to prevent the user from registering too many bookmarks and losing track of which scene to return to.

[0023] More preferably, the recording / reproducing apparatus is further connected to a content distribution information recording unit that stores a start time and an end time of the content, which are distributed via a wire or wirelessly, and is connected to the content distribution information recording unit. Content bookmark storage means for storing the start time and end time of the content currently being reproduced as a bookmark, and the first bookmark erasing means is connected to the slow reproduction instruction bookmark storage means and the content bookmark storage means, And a second bookmark erasing means for erasing the bookmark stored in the slow reproduction instruction bookmark storing means and the content bookmark storing means when the channel of the content to be changed is changed.

Here, is used for displaying video in the recording / reproducing device, but may be used as a device that uses other content (for example, when the content is audio, an audio reproducing device).

In this embodiment, the recording / reproducing apparatus will be described as a recording / reproducing apparatus for a distributed TV (television) program.

Referring to FIG. 2, distribution information (content title, channel name, broadcast time) of each content is recorded in content distribution information recording section 4. The stored content distribution information is displayed on the display device 8.
Can be displayed on the display.

Referring to FIG. 3, a description will be given of a process in which the recording / reproducing apparatus receives and displays a content.

The communication section 1 receives content information distributed via a wired or wireless communication network (step S).
1). The content information received in step S1 includes:
Content and content distribution information,
The information is determined at the time of reception (step S2).
If the received information is the content distribution information (NO in step S2), the content distribution information extraction unit 2 extracts the content distribution information (step S3) and records it in the content distribution information recording unit 4 (step S4). .

If the received information is a content (YES in step S2), the content extracting unit 3 extracts the content (step S5). The content recording execution determination unit 6 determines whether to record the extracted content in the recording unit 7 (Step S6). The determination of the content recording here is set in advance by the user, and is managed by the time shift table 14 from the input unit 9 via the input operation determining unit 10. The content recording execution determination unit 6 controls the time shift table 14 via the control unit 5.
The information on whether to record the content is extracted and determined. The details of the time shift table 14 will be described later.

If it is determined that the content is to be recorded (YES in step S6), the content is recorded in recording section 7. The recording here includes recording the content as it is on a recording device such as a hard disk that can be randomly accessed, as well as compressing and recording the content. The content recorded in step S7 is instantaneously expanded by the control unit 5 (step S8) and displayed on the display device 8 (step S10).

If it is determined that the content is not to be recorded (NO in step S6), the content is displayed on display 8 as it is (step S10).

With reference to FIG. 4, the management contents of the time shift table 14 used in the determination in step S6 will be described. The content of the time shift table 14 is determined by the input operation determining unit 10 according to an instruction from the input unit 9,
Be updated. The time shift table 14 contains data necessary for time shift control.

When any action relating to the time shift occurs, the control unit 5 performs control with reference to the time shift table 14. The management items of the time shift table include “A: whether or not to reproduce a received video while recording it”, “B: recording capacity (time)”, and “C:
"Slow playback start time indicating how many seconds before the time when the time shift started, the slow playback start time", "D:
"Slow playback end time indicating how many seconds after the time when the time shift was started until the video is played back in slow motion", "E:
Slow playback speed "," F: number of replay repetitions ", and the like.

Referring to FIG. 5, when the content is displayed on display device 8 in step S10 of FIG.
The operation when the time shift button is pressed will be described in detail. Here, the time shift button is a button that changes the normal playback of the displayed content. It has a function to return to the original playback state.

When a time shift button is pressed from the input unit 9 while the content is being reproduced on the display device 8 (step S).
20), the input operation judging section 10 sets the time shift table 1
4 to determine whether or not the content is currently being recorded in the recording unit 7 (step S21). If the content has not been recorded in the recording unit 7 (NO in step S21), the input operation determination unit 10
The content recording execution determination unit 6 is instructed to record the content via (step S22). At this time, the item (A in FIG. 4) indicating whether or not to record the content in the time shift table 14 is changed to “temporarily record the content”. However, since this item is set so that the user does not record the content, the content is automatically changed to “do not record the content” when the time shift function ends.

[0038] The content recording execution determining section 6 which has been instructed to record the content in step S22 displays the received content on the display device 8 while recording it in the recording section 7 (step S23).

After the processing in S23, or when the content is being recorded in the recording section 7 (YE in S21).
S), the input operation determination unit 10 determines the time during which the user has pressed the time shift button of the input unit 9 (Step S2).
4). That is, it is determined whether the time when the time shift button is pressed is equal to or longer than a predetermined time.

If the time shift button is pressed for a predetermined time or more, the video is temporarily stopped, and if the time is shorter than the predetermined time, slow reproduction is performed.

If the time during which the time shift button is pressed is equal to or longer than a certain time (S24), the image displayed on the display device 8 is temporarily stopped. The video recorded in the recording unit 7 is updated from the oldest one to the newest one. Therefore, the paused video is recorded in the recording unit 7 only for a certain period of time. Therefore, when the paused video becomes oldest or the pause is released (YES in step S32), the next video is automatically reproduced from the paused video (step S35).

If the time for which the time shift button is pressed is less than a certain time (less than a certain time in step S24), the content is slow-reproduced. Is determined (step S27). If the recorded data is not recorded in the recording unit 7 (No in step S27), the “slow reproduction end time” and the “slow reproduction speed” are confirmed in the time shift table 14 shown in FIG. Display device 8
, Slow playback is started from the point in time when the time shift button is pressed (step S28). When the video from the start of the slow playback to the slow playback end time is played (step S29), the process returns to the point in time when the time shift button is pressed again (NO in S33), and the slow playback is repeated. During the slow reproduction, the video of the recording capacity for the time shift is recorded in the recording unit 7, and the video of the slow reproduction portion becomes the oldest, or the slow reproduction is replayed by the number of replay repetitions of the time shift table 14. When the slow playback is canceled by an instruction from the input unit 9 (YES in step S33), the slow-playing video becomes a normal speed and is automatically played without replay (step S35). ).

If the recording data has been recorded in the recording section 7 (Yes in step S27), the slow reproduction starts from the point in time when the time shift button is pressed (step S30). It returns to the time (step S31), and the slow reproduction is repeated (NO in S31). During the slow reproduction, the content corresponding to the recording capacity for the time shift is recorded in the recording unit 7, the content of the slow reproduction start time portion becomes the oldest, the slow reproduction is replayed by the number of replay repetitions of the time shift table 14, If the slow playback is canceled by an instruction from the input unit 9 (YE in step S34)
S), the slow-reproduced video becomes the normal speed,
It is automatically reproduced without replay (step S
35).

If YES in step S33 and YES in step S34, both slow-reproduced contents are reproduced by changing only the speed.

Next, the reproducing operation during this time shift will be described based on the time axis. FIG. 6 illustrates a series of operations in steps S25 and S32 in FIG. Until t = T0, the video is reproduced while being recorded. At this time, the video is stored in the
Recorded before. Here, the time B is the recording capacity (time) for the time shift described in FIG. When the playback is paused at t = T0, the video being played is stopped. t
= T1 (T1> T0), the video is paused, so the video at t = T0 is displayed. At this time, the video up to t = T1 is recorded in the recording unit 7, but the time shift recording capacity (time) is constant. For this reason, old videos are sequentially deleted. Therefore, t = B
, The paused video starts normal playback.

Referring to FIG. 7, when no image is previously recorded in recording unit 7, the operation for each time when the time shift button is pressed for less than a predetermined time (step S2 in FIG. 5).
8, S29 and S33) will be described. t = T0
When the time shift button is pressed, the displayed video is played back in slow motion. At t = T1, the recorded video is from t = T0 to t = T1. At this point, when the slow playback is performed until the slow playback end time D described with reference to FIG. 4, the process returns to t = T0, and the slow playback is performed. t =
Also at T2 (T1 <T2 <B), the slow reproduction operation from T0 to D is performed. When t = B, the video is sequentially deleted from the video at T = T0 recorded in the recording unit 7. For this reason, from the point of time t = T2, the normal reproduction is returned from the slow reproduction. For example, the operation when the time (B + α) has elapsed is illustrated.

Referring to FIG. 8, when an image is recorded in the recording unit 7 in advance, an operation for each time when the time shift button is pressed for less than a predetermined time (step S30 in FIG. 5,
S31 and S34) will be described. When the time shift button is pressed at t = T0, the displayed video is played back in slow motion. When the reproduction is completed up to the slow reproduction end time D, the process returns to the slow reproduction start time C and the slow reproduction is continued again. When the slow reproduction is repeated until t = BC, the images at t = T0-C recorded in the recording unit 7, that is, the first video of the slow reproduction are sequentially deleted. Therefore, the playback automatically returns from the slow playback to the normal playback from the point in time t = BC.

FIGS. 6 to 8 illustrate the case where the release operation has not been performed for a certain period of time after the time shift button has been pressed. When the slow reproduction is repeated the number of times of the replay, the normal reproduction is automatically returned.

Referring to FIG. 9, a description will be given of a method of displaying an image displayed on display device 8 when a normal reproduction operation is changed to a slow reproduction operation. In the case of normal reproduction, the video received by the communication unit 1 is displayed in real time on the display device 8 via the content recording execution determination unit 6 or the recording unit 7. It is assumed that normal video data is composed of 60 frames per second. When the time shift button is pressed and the slow motion playback is transmitted from the input operation determination unit 10 to the control unit 5, the control unit 5 reads the value of the slow playback speed in the time shift table 14. If the value of the slow playback speed is, for example, 0.8 times speed, the control unit 5 determines the slow playback speed in accordance with the slow playback speed of the time shift table 14 to 60
× 0.8 = 48 frames of video is assumed to be video for one second. By constructing an image obtained by dividing the 48 images into 60 frames and displaying the image on the display device 8 as usual, slow playback becomes possible.

Next, a description will be given of a method of simultaneously displaying a slide as shown in FIG. 10 during the slow reproduction as described above and simply striping the scene. The operation when the time shift button is pressed in step S20 of FIG. 5 will be described with reference to FIG. When the time shift button is pressed from the input unit 9 while the content received by the communication unit 1 is displayed on the display device 8 (step S20), the input operation determination unit 10 detects how the time shift button is pressed, It is determined whether or not the playback is slow, depending on how the button is pressed (step S40).

If it is not slow reproduction (N in S40)
O), the program is terminated without releasing the slide while the screen is paused.

In the case of slow playback (YE in S40)
S), the input operation determining unit 10 instructs the control unit 5 to perform slow reproduction. The control unit 5 refers to the time shift table 14 and displays a slide on the display device 8 based on the value set in the time shift table 14 (Step S42). The slide will be described later in detail with reference to FIG. Simultaneously with the display of the slide, slow reproduction is started (step S43). At that time, the control unit 5 sets the playback time of the video information recorded in the recording
Is written into the content writing unit 12 from the time shift table 14. The content writing unit 12 stores the start time / end time of the video recorded in the recording unit 7 that changes as needed, the time when the time shift button is pressed, and the slow reproduction start time / end time before and after the time. Have been. After the slow playback is started, the control unit 5 controls the input unit 9
It is determined whether there is any input to the slide (step S44).

If there is no input to the slide from the input unit 9 (No in step S44), the slow-reproduced video becomes the oldest, the replay is repeated the number of times, or the slow replay is canceled. It is determined whether or not it has been performed (step S45). If none of the conditions in step S45 is satisfied, the process returns to step S44.

If any of the conditions in step 45 is satisfied (step S45 is satisfied), the displayed slide disappears (step S46), and the process returns to the normal reproduction operation (step S47).

When there is an input to the slide from the input unit 9 (Yes in step S44), the input operation determining unit 1
0 determines what to change in the slide (step S48). When the slow playback start point slide bar in FIG. 10 is moved, the video at the slow playback start point is checked (step S49). At this time, moving the slide bar also changes the image displayed on the display device 8 following the slide bar. At this time, the slow playback is stopped, and the video at the slow playback start point specified by the slide bar is displayed. When the slow playback start point is determined, the slow playback start point is fixed by the user pressing the slide bar, and the slow playback start point is recorded in the content writing unit 12 (step S50). Thereafter, after the slow reproduction before operating the slide bar is started (step S51), the process returns to S44.

When the slow reproduction end point slide bar in FIG. 10 is moved, the video of the slow reproduction end point is confirmed (step S52). At this time, moving the slide bar also changes the image displayed on the display device 8 following the slide bar. At this time, the slow playback is stopped, and the video at the slow playback end point specified by the slide bar is displayed. When the slow reproduction end point is determined, the user presses the slide bar to fix the slow reproduction end point, and the slow reproduction end point is recorded in the content writing unit 12 (step S53). Thereafter, after the slow reproduction before operating the slide bar is started (step S51), the process returns to S44.

When the scene write button on the slide in FIG. 10 is pressed, the control section 5 instructs the content write section 12 to write, and the control section 5 starts the slow reproduction start point stored in the content write section 12. An operation of writing the video at the slow reproduction end point is performed (step S54). The video written in step S54 is stored in the content storage unit 13 (step S55). Thereafter, after the slow playback before operating the slide bar is started (step S51), S44 is performed.
Return to

The slide will be described in more detail with reference to FIG. This slide is displayed when slow reproduction is started in step S42 of FIG. The slide is displayed on a part of the display device 8. The slow playback start point slide bar and the slow playback end point slide bar have scroll bar and button functions.

As described with reference to the flowchart of FIG. 11, the operation of the slow reproduction start point in step S49 is performed by moving the slow reproduction start point slide bar forward and backward, so that the display device 8 displays the slow reproduction start point. The image is displayed. By pressing the slow reproduction start point slide bar, the slow reproduction start point is determined, and the slow reproduction is started. In the operation of the slow reproduction end point in step S52 in FIG. 11, the same operation can be realized by sliding or pressing the slow reproduction end point slide bar. In addition, by pressing the scene writing button in step S54 of FIG. 11, writing of a video is executed. At this time, the slow reproduction is still executed.

Next, the function of the bookmark management unit 11 will be described. The bookmark function is a function that has a timetable synchronized with a video and sets a flag corresponding to a scene in the video on the timetable so that the user can move to the scene with one button. The flag is called a bookmark. In an ordinary random access recording / reproducing apparatus, a user watching a video can instantaneously access a desired scene by pressing a button. In the content distribution information recording unit 4 of FIG. 1, the start time and the end time of the program are recorded for each channel as shown in FIG. When the power of the recording / reproducing apparatus is turned on and when the channel is changed, the control unit 5 reads the start time / end time of the channel from the content distribution information recording unit 4 and registers it in the bookmark management unit 11.

The time at which the time shift button is pressed to pause or slow-play the displayed video is registered as a bookmark. Also, when the channel is changed, the control unit 5 does not operate except during slow playback.
Deletes the bookmark data registered in the bookmark management unit 11. At the same time, the control unit 5 registers the channel change point as a bookmark, reads the start time and end time of the channel from the content distribution information recording unit 4, and registers it in the bookmark management unit 11.

When a channel is changed during slow playback, bookmarks other than the slow playback point are erased, and the start time, end time,
Channel changes are registered as bookmarks.

Referring to FIG. 12, the bookmark creation processing will be described. When the recording / reproducing apparatus is started up by turning on the power (step S60), the control unit 5
Reads the start time and the end time from the content distribution information recording unit 4 based on the channel of the program displayed on the display device 8, and registers them as bookmarks in the bookmark management unit 11 (step S61). The input unit 9 determines whether a channel change operation has been performed (step S62).

If the channel change operation has been performed (Yes in step S62), the control unit 5 deletes the bookmark information managed so far by the bookmark management unit 11 (step S63). The bookmark is deleted and the time when the channel is changed is recorded as a bookmark in the bookmark management unit 11 (step S64). The start time and the end time of the program broadcast on the changed channel are read from the content distribution information recording unit 4 and recorded in the bookmark management unit 11 (step S65).

After step S65 or when there is no channel change (No in step S62), it is determined whether or not a special reproduction operation has been performed by pressing the time shift button of the input unit 9 (step S66). When the special reproduction operation is performed (Yes in step S66), the time when the time shift button is pressed (special reproduction point)
Is recorded in the bookmark management unit 11 as a bookmark (step S67).

After step S67, or when the special reproduction operation is not performed (No in step S66),
It is determined whether the power of the recording / reproducing apparatus has been turned off (step S68). If the power has been turned off (YES in step S68), the bookmark is deleted. When the power is turned on (NO in step S68), the process returns to step S62.

The bookmark is constantly changing while the recording / reproducing apparatus is operating. When a video with a bookmark is included in the content recorded in the recording unit 7 of the recording / reproducing apparatus, it is possible to jump to the video with a bookmark. By automatically creating a bookmark in this way, it is not necessary to provide a button for creating a bookmark in the input unit 9.

As described above, according to the present embodiment, when an image such as a decisive moment is displayed while viewing an image, it is possible to slowly reproduce the images before and after the scene with one button. Become.

In the case of a soccer goal scene or the like, the viewer often performs a replay operation when a shot is decided. As a result, the player's form and confirmation of the quick technique can be seen in the slow playback. Moreover, there is no need to spend time on operations for automatically and repeatedly reproducing the scene. Also, since you can see the performance of the players after the goal scene,
It's nice for that player's fans.

If a time shift button is pressed at the end of the golf swing while watching a golf image, the image from the first swing of the golf to the end of the golf can be watched in slow motion. In addition, the trajectory of the golf ball after the end of the swing can be checked together.

Also, in the case of a broadcast such as English conversation, if a slow reproduction is performed from a place where it becomes impossible to hear, it is possible to listen while confirming the conversation from a little before to a little after the part which could not be heard. For this reason, the recording / reproducing apparatus is effective even when the voice cannot be heard. Further, since the slide is displayed at the time of the slow playback, the slow playback end time can be extended by a simple operation.

Further, by extracting and storing only critical moments in baseball, golf, soccer, and the like using slides, it is possible to view them later.

As described above, in the recording / reproducing apparatus, it is possible to use only the time shift function with a fixed capacity without using a useless recording capacity, and it is possible to record only necessary scenes. In addition, it is possible to create bookmarks automatically. For this reason, it is not necessary to provide a button for adding a bookmark to the input unit, and it is possible to prevent the user from taking time to perform the operation. Also, when the channel is changed, the previous bookmark is automatically deleted. For this reason, it is possible to prevent the user from registering too many bookmarks and losing track of which scene to return to.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
