Description

The present invention relates to an AV playback apparatus and AV playback method for playing back audio and video of AV content.

  In an AV playback apparatus that plays back audio and video of AV (Audio Visual) content, in order to quickly access and play back a desired scene in the middle of the AV content, the video or the like is, for example, double speed, quadruple speed, 8 It has fast forward / fast reverse functions that fast forward in the forward direction of playback at speeds such as double speed and 16x speed, and fast reverse in the reverse direction of playback, and operates these functions to reach the video of the desired scene. When this is done, AV content can be played using the reached scene as a playback point. FIG. 5 shows a procedure in which a video is fast-forwarded at a speed that is eight times the normal playback speed, which is a normal viewing speed of AV content, and a desired playback point is selected and played back. On the screen of the display unit 101 that reproduces and displays AV content, a playback button (Play button) 102 for playing back video and audio at a steady playback speed, a fast-forward button 103 for fast-forwarding, and a fast-forwarding button 103 A fast reverse button 105 is displayed. When the fast-forward button 103 is touch-operated to quickly access a desired scene in the middle of AV content reproduction, the video is fast-forwarded at, for example, 8 times speed (other speeds can be set depending on the setting). For example, when a desired image 106 is found after 40 seconds in real time from the start of fast-forwarding (8 times speed: an image after 400 seconds), an image 400 seconds after the start of fast-forwarding by touching the playback button 102 AV content can be played at a steady playback speed from the beginning, but when the desired image is in the latter half of the AV content, etc., it is necessary to watch from the original image in order, and this is equivalent to accessing the desired image It took a lot of time and effort.

  In order to solve the above-described problem, a disc playback apparatus has been proposed that can operate a fast-forward function at a predetermined double speed to quickly access a desired image and perform playback (see, for example, Patent Document 1). In the disc playback apparatus described in Patent Document 1, when fast-forward playback or fast-rewind playback is performed, the head frame of each scene is sequentially played back so that the video of the head portion of each scene is displayed sequentially. A desired scene can be accessed efficiently.

JP 2002-44611 A

  According to the disc playback apparatus, a desired scene can be quickly played back by a fast reverse / fast forward function. For example, instead of an infant watching at the rear seat, fast forward / fast reverse can be performed at the driver's seat. When operating the vehicle or the like, the display screen cannot be watched while driving the vehicle, making it difficult to select a desired scene. It is difficult to select a reproduction point while paying attention to the screen not only during driving of the vehicle but also when performing machine operation or observation.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide an AV playback apparatus that can easily select a desired playback point without gazing at the screen in fast-forward / fast-reverse operations for AV content and the like. To do.

  In order to solve the above-described problems, an AV playback apparatus according to the present invention plays back playback input means that receives playback start of AV content to be played back, and audio and video of AV content that is received by the playback input means. An AV content playback unit, and playback control means for playing back the AV content at a steady playback speed by the AV content playback unit, wherein the playback control means sends the video to the steady playback speed. High-speed video reproduction control means for reproducing at a higher high-speed video reproduction speed, confirmation audio reproduction control means for reproducing the audio at a confirmation audio reproduction speed smaller than the high-speed video reproduction speed, the high-speed video reproduction control means, When the audio and video of the AV content are being reproduced according to the control by the confirmation audio reproduction means, And a confirmation voice skip control means for skipping the playback point of the audio in the AV content at a speed greater than the confirmation voice playback speed. The playback input means is controlled by the confirmation voice playback control means. Voice selection point input means for receiving selection of a voice selection point to be played at a steady playback speed from voice played at a confirmation voice playback speed, and the playback control means is selected by the voice selection point input means The AV content is played back by the AV content playback unit at a steady playback speed from the audio selection point.

  According to such a configuration, the AV content video is played back at a high speed video playback speed higher than the steady playback speed, and the audio of the AV content is played back at a confirmation audio playback speed lower than the high speed video playback speed. Since the selection of the voice selection point to be played back at the steady playback speed is received from the voice at the confirmed voice speed and the AV content is played back at the steady playback speed from the voice selection point, for example, an AV playback device is mounted on the vehicle. Even when the driver is traveling, a desired playback point of the AV content can be easily selected without gazing at the screen. Further, in order to select the audio selection point to be reproduced at the steady reproduction speed from the audio reproduced by the confirmation audio reproducing means, the confirmation audio reproduction speed is set smaller than the high-speed video reproduction speed. By skipping the audio playback point at a speed greater than the confirmation audio playback speed, it is possible to adjust the deviation from the playback video at a high video playback speed. For example, the audio playback point in the AV content can be skipped at a speed larger than the confirmation audio playback speed, and it is possible to catch up with the video played at the high speed video playback speed. The “predetermined rule” is a predetermined rule such as a skipping speed, a skip timing, and the like, and includes a video high-speed playback speed, a confirmation audio playback speed, and the like. In addition, “steady playback speed” is a playback speed for viewing audio and video of AV content, and “video fast playback speed” is a speed for fast-forwarding and rewinding video, twice the normal playback speed, Speeds of 4 times, 8 times, 16 times, etc. correspond, and “confirmation sound playback speed” is a playback speed set to select a desired playback position by playback sound, as will be described later, and is heard by hearing. It is in the range of possible speeds and includes steady playback speed or speeds slightly higher than steady playback speed.

  In the AV playback device according to the present invention, the confirmation sound playback speed may be the same as the steady playback speed or a speed difference between the steady playback speed and a predetermined range.

  According to such a configuration, when the AV content video is played back at a high speed video playback speed, in order to enable selection of a playback point according to the played back audio, the confirmation audio playback speed of the AV content voice is set to The speed difference between the steady playback speed and the steady playback speed is within a predetermined range. “Within a predetermined range” refers to a range in which a user can select a playback point from a sound played back at a confirmation voice playback speed with respect to a steady playback speed that is a playback speed for viewing AV content. is there.

  In the AV playback device according to the present invention, the confirmation voice skip control means may be configured to skip the playback point of the voice every predetermined time.

  According to such a configuration, since the playback point is skipped at a predetermined time for the audio reproduced at the confirmation audio reproduction speed, the image reproduced at the high-speed image reproduction speed that is higher than the confirmation audio reproduction speed is used. It becomes possible to eliminate the time shift. This makes it possible to match the content of the video to be reproduced by skipping with the content of the reproduced audio.

  In the AV playback apparatus according to the present invention, the playback input means includes video selection point input means for accepting selection of a video selection point of a video played at a high speed video playback speed by the high speed video playback control means, The playback control means may be configured to play back the AV content at the AV content playback section at a steady playback speed from the video selection point selected by the video selection point input means.

  According to such a configuration, it is possible to select a video selection point that is a desired playback position from a video played at a high video playback speed. For example, when a vehicle is stopped, video selection is performed from a video that is played back at high speed. By selecting and inputting points, AV content can be played back at a steady playback speed from the position of the selected video selection point.

  In the AV playback device according to the present invention, the selection of the video selection point to the video selection point input means is performed by a touch operation on a predetermined button area of a display screen of the display unit on which the AV content is played back and displayed. The selection of the voice selection point to the voice selection point input means can be performed by a touch operation on the remaining area of the display screen excluding the button area.

  According to such a configuration, since the selection of the voice selection point can be performed by a touch operation on the remaining area excluding the button area on the display screen, for example, the button area is excluded even during driving. The remaining area, which can be selected by touching any part of the screen, eliminates the need to watch the screen and does not hinder driving operations.

  The AV playback device according to the present invention has vehicle traveling state detection means for detecting whether a vehicle equipped with the AV playback device is in a running state or a stopped state, and the playback control means When the state detection unit detects the vehicle as a running state, the reception of the selection of the video selection point by the video selection point input unit can be stopped.

  According to such a configuration, when the AV playback device is mounted on the vehicle, the selection of the video selection point is stopped when it is detected that the vehicle is in a running state. This makes it possible to reproduce AV content, so that the screen is not watched and the driving operation is not hindered.

  Furthermore, in order to solve the above-described problem, an AV playback method according to the present invention includes a playback input step for receiving a playback start of AV content to be played back, and audio and video of the AV content for which the playback start is received by the playback input means. And a playback control step for playing back the video at a steady playback speed by the AV content playback unit, wherein the playback control step plays back the video at a higher video playback speed than the steady playback speed. According to the control in the reproduction control step, the confirmation audio reproduction control step for reproducing the audio at a confirmation audio reproduction speed smaller than the high-speed image reproduction speed, and the control in the high-speed image reproduction control step and the confirmation audio reproduction step. When playing back the audio of the content and the video, according to a predetermined rule, A confirmation voice skip control step for skipping the playback point of the audio in the V content at a speed larger than the confirmation voice playback speed, and the playback input step is performed at the confirmation voice playback speed by the confirmation voice playback control step. A voice selection point input step of accepting selection of a voice selection point to be played back at a steady playback speed from the played back voice, wherein the playback control step is based on the voice selection point selected in the voice selection point input step; The AV content is played back by the AV content playback unit at a steady playback speed.

  In the AV playback method according to the present invention, the confirmation voice playback speed may be the same as the steady playback speed or a speed difference between the steady playback speed and a predetermined range.

  The AV playback method according to the present invention may be configured such that the confirmation voice skip control step skips the playback point of the voice every predetermined time.

  In the AV playback method according to the present invention, the playback input step includes a video selection point input step of accepting selection of a video selection point of the video played at a high speed video playback speed by the high speed video playback control step, The playback control step may be configured to play back the AV content at the AV content playback unit at a steady playback speed from the video selection point selected in the video selection point input step.

  In the AV playback method according to the present invention, the selection of the video selection point in the video selection point input step is performed by a touch operation on a predetermined button area of a display screen of the display unit on which the AV content is played back and displayed. The selection of the voice selection point in the voice selection point input step can be performed by a touch operation on the remaining area of the display screen excluding the button area.

  An AV playback apparatus system including an AV playback apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  An AV playback system 10 including an AV playback device 11 according to the first embodiment of the present invention is configured as shown in FIG.

  In FIG. 1, an AV playback device 11 that is an in-vehicle device having a navigation function includes a processing unit 13 including a computer unit (including a CPU, a ROM, a RAM, an interface, a bus, and the like). The processing unit 13 includes an AV unit 15 capable of reproducing various sound sources and video sources (for example, CD and DVD), and a navigation unit 17 (GPS receiver, gyro equipment, acceleration sensor, etc.) capable of navigating the host vehicle. Are included). In addition, a speaker 18 is connected to the processing unit 13 via an output circuit 19. As a result, an audio signal related to processing by the AV unit 15 and the navigation unit 17 can be output as audio from the speaker 18 via the output circuit 19. In addition, the processing unit 13 includes a storage unit 20 (for example, a hard disk, a flash memory, etc.) capable of storing various information such as music information and map information used in the AV unit 15 and the navigation unit 17 and applications related to AV playback. And a display unit 21 that displays images and the like associated with various processes configured by an LCD or the like, and an operation unit 23 that can input instructions necessary for various processes formed on the display unit 21 in a touch panel format. Has been. The operation unit 23 includes an input button using a hard key in addition to the touch panel type described above.

  Further, a rear seat display device 25 that is viewed by a passenger in the rear seat of the vehicle is connected to the processing unit 13 of the AV playback device 11 that is an in-vehicle device. The rear-seat display device 25 inputs a rear-seat display unit 26 that displays an image or the like composed of an LCD or the like, and instructions necessary for various processes formed on the rear-seat display unit 26 in a touch panel format. It is composed of a possible rear seat operation unit 27 and is connected to these processing units 13. The rear seat operation unit 27 includes an input button using hard keys in addition to the touch panel formation described above. The AV playback device 11 and the rear seat display device 25 constitute an AV playback system 10.

  In the AV playback system 10 described above, processing is performed according to the procedure shown in FIG. Specifically, the processing unit 13 of the AV playback device 11 plays back video and audio of AV content according to the procedure shown in FIG. Hereinafter, the operation procedure of the processing unit 13 will be described with reference to FIG. 2 and FIG. 3 which is a timing chart of video reproduction and audio reproduction.

  In FIG. 2, the processing unit 13 reproduces desired AV content from its starting point by selection by touching a predetermined button on the operation unit 23 (S11). When the user wishes to reproduce from a predetermined scene in the middle of the reproduced AV content, the user can quickly access the desired scene by operating the fast forward function and the fast reverse function. For example, when the user wants to play from a scene in the middle of the AV content that he / she viewed last time, or when he / she wants to repeatedly view a predetermined scene of the AV content, the fast-forward function for fast playback in the forward direction, and fast playback in the reverse direction The fast reverse function is operated.

  When the playback button (Play button) 23a of the touch panel type operation unit 23 provided on the display screen 21a of the display unit 21 shown in FIG. 3 is touched, the AV content is played back at a steady playback speed, and the fast-forward button 23b is touched. Then, the video is fast-forwarded in the playback forward direction (in this embodiment, eight times the normal playback speed), and when the fast-rewind button 23c is touched, the video is fast-backed in the reverse playback direction (also eight times the normal playback speed). Speed).

  The processing unit 13 detects the presence or absence of the touch operation of the fast-forward button 23b or the touch operation of the fast-rewind button 23c by the user (S12). When the processing unit 13 detects a touch operation of the fast-forward button 23b or a touch operation of the fast-return button 23c (YES in S12), the processing unit 13 is set to a predetermined double speed (high-speed video reproduction speed: for example, 8 times normal speed). And fast-forward playback or fast-reverse playback, and skip playback at a predetermined speed (confirmation audio reproduction speed: for example, a speed equal to the normal reproduction speed) (S13: high-speed video reproduction control means, confirmation audio reproduction control means, Confirmation voice skip control means). Since the speed range in which audio can be heard and compared compared to video is rather narrow, audio is played at a confirmation audio playback speed that is smaller than the high-speed video playback speed, and for time adjustment with fast-forward video. In addition, skip playback is performed by omitting playback of part of the audio.

  An example of video playback at the above-described high-speed video playback speed and audio skip playback at the confirmation audio playback speed will be described with reference to FIG. The example shown in FIG. 3 is fast-forward playback at a speed that is eight times the normal playback speed, which is the playback speed for viewing AV content, and the confirmation playback speed (same playback speed as the normal playback speed in this embodiment) for audio. Playing. Real-time (actual time) from the start of fast-forward playback 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds, and 60 seconds After 80 seconds at playback speed (1 minute 20 seconds), 160 seconds (2 minutes 40 seconds later), 240 seconds (4 minutes later), 320 seconds (5 minutes 20 seconds later), 400 seconds later ( The video corresponding to 6 minutes 40 seconds later and 480 seconds later (8 minutes later) is reproduced. Although not shown in FIG. 3, the video is played back at the same high playback speed as described above.

  On the other hand, the audio is skipped at the confirmation audio reproduction speed. Specifically, the audio of the AV content after 0 to 10 seconds is played back at the confirmation voice playback speed (= steady playback speed) between 0 seconds and 10 seconds in real time from the start of fast-forward playback. Also, between 10 seconds and 20 seconds after the actual time, the audio of the AV content after 1 minute 20 seconds to 1 minute 30 seconds is also reproduced at the same confirmation sound reproduction speed. In the same manner as described above, after 20 seconds to 30 seconds, after 30 seconds to 40 seconds, after 40 seconds to 50 seconds, and after 50 seconds to 60 seconds, after 2 minutes and 40 seconds at the confirmation playback speed. After 2 minutes 50 seconds, 4 minutes later 4 minutes 10 seconds later 5 minutes 20 seconds later 5 minutes 30 seconds later and 6 minutes 40 seconds later 6 minutes 50 seconds later, the audio of the AV content is reproduced. Playback of audio other than the above is omitted. Although not shown in FIG. 3, the audio of the AV content is reproduced at intervals similar to the above.

  As described above, in fast-forward playback of AV content, audio playback is skip playback in which midway audio is skipped at intervals of 10 seconds for video played at a high-speed video speed of 8 times speed. By the skip reproduction, the reproduced video and the reproduced audio coincide with each other in the first part of each 10 seconds.

  The processing unit 13 detects whether or not a playback point is selected at a steady playback speed in the fast-forward playback of the AV content described above (S14). The processing unit 13 continues the fast-forward playback of the AV content until the playback point is selected, except when there is an operation for stopping the fast-forward playback (NO in S14). The processing unit 13 detects whether the selection of the playback point of the AV content is a selection based on an audio point or a video point (S15). Selection of a video selection point for starting AV content playback at a steady playback speed from a video played at a high-speed video playback speed of 8 × speed is performed by touching the playback button 23a on the display screen 21a of the display unit 21 or Selection of an audio selection point for starting AV content playback at the normal playback speed of audio skipped at the confirmation audio playback speed is performed by a touch operation on the video display area 21b excluding the buttons 23a to 23c on the display screen. Done. Selection of a video to be played back at high speed with 8 × fast-forwarding is possible by selecting the video selection point by touching the playback button 23a because the video is watched and selected. The selection of the audio selection point is made by a touch operation on the video display area 21b, which is a wide area on the display screen 21a, so that the selection can be made without gazing at the screen. Thereby, the selection of the voice selection point is possible without gazing at the screen.

  When the video selection point is selected (S15: video selection point input means), the processing unit 13 plays AV content from the selected video selection point (S16: playback control means). For example, as shown in FIG. 3, when a video is played back at a fast forward speed of 8 times, a fast-played video (video 6 minutes after the start) is 45 seconds after the start of fast-forward playback. Is selected as a video selection point (touch operation on the playback button 23a), the video and audio of AV content 6 minutes after the start of playback are played back at a steady playback speed.

  On the other hand, when the audio selection point is selected (S15: audio selection point input means), the processing unit 13 reproduces AV content from the selected audio selection point (S17: reproduction control means). For example, as shown in FIG. 3, when a sound reproduced at a confirmation audio speed (= steady reproduction speed) is selected as an audio selection point after 45 seconds in real time from the start of fast-forward reproduction (video display area 21b). In the range from 40 seconds to 50 seconds after the start of fast forward playback, the sound in the range from 5 minutes 20 seconds to 5 minutes 30 seconds after the start of fast forward playback is being played back. The voice after 5 minutes and 25 seconds is selected as the voice selection point. Accordingly, the video and audio of AV content 5 minutes and 25 seconds after the start of fast-forward playback is played back at a steady playback speed. In this way, even during fast-forward playback, even when the video is being played at high speed, playback is performed at the confirmation audio playback speed that is the same speed as the steady playback speed or at a speed close to it, and skips the time difference from the video that is played back at high speed. It was adjusted with. As described above, after 45 seconds in real time from the start of fast-forward playback, the video is displayed 360 seconds after fast-forward playback (6 minutes later), and the audio is 5 minutes and 25 seconds from the start of fast-forward playback. Although it is output, skip playback can match the time difference from the video played back at high speed at regular intervals (every 10 seconds).

  As described above, even in the case of fast-forward playback, since the audio is skip-played at the confirmation voice playback speed, it is possible to select a playback point (voice selection point) by voice, and the selection of the voice selection point can be made on the display screen 21a. Since it is determined by the touch operation on the video display area 21b, the selection operation can be performed without gazing or gazing at the display screen 21a even during machine operation, driving operation, or the like.

  In this embodiment, the selection of the audio selection point in the case of fast-forward playback has been described, but the same applies to the case of fast-rewind playback. In the case of fast-forward playback, the playback direction is the playback direction of AV content, whereas in the case of fast-rewind playback, the playback direction is the reverse playback direction of AV content. On the other hand, in the case of audio, playback is performed at the confirmation audio playback speed in the AV content playback forward direction in both fast-forward playback and fast-rewind playback. For example, when switching to fast-reverse playback at 60 seconds after the actual time shown in FIG. 3, the video is played back at a high-speed video playback speed at 8 × speed in the reverse playback direction from the video after 8 minutes at the time of the switching. For 10 seconds after the start of reverse playback, for example, 7 minutes 50 seconds to 8 minutes later is played in the forward direction at the confirmation voice playback speed, and then the next 10 seconds are 6 minutes 30 seconds later by skip playback. The sound after -6 minutes 40 seconds is reproduced in the forward direction. Thereafter, the audio is skip-played at similar intervals. That is, in the case of reverse playback such as fast rewinding, the audio skip direction is reverse, but playback at the confirmation audio speed after skip is played in the forward direction. As a result, even in the case of fast rewinding, the sound is reproduced in the forward direction at the confirmation sound speed, so that a reproduction point (sound selection point) can be selected. The same video is reproduced and displayed on the display screen of the display unit 21 and the display screen of the rear seat display unit 26 of the rear seat display device 25. In addition, playback operation including fast forward, fast reverse, etc., selection of audio selection points, and selection of video selection points are also possible from the rear seat operation unit 27. Further, although the confirmation voice reproduction speed is the same as the steady reproduction speed, it may be higher than the regular reproduction speed if it can be discriminated. It is also possible to change the skip playback speed, interval, and the like.

  Next, an AV playback system including the AV playback device according to the second embodiment of the present invention will be described. In this embodiment, the same parts as those in the first embodiment are denoted by the same names and the same reference numerals, and different points will be mainly described. The main difference from the first embodiment is that when a vehicle (not shown) equipped with the AV playback device 11 that is an in-vehicle device is running, selection of playback points during fast forward playback and fast reverse playback is possible. It is a point that only selects a voice selection point. By stopping the selection of the video selection point, forward carelessness due to the driver's gaze on the screen during the driving operation is prevented.

  AV content playback start (S21), fast-forward / fast-reverse operation detection (S22), video playback at a high-speed video playback speed after detection of fast-forward / fast-reverse operation, and skip playback based on audio confirmation playback speed (S23) ) Is the same as in the first embodiment. The processing unit 13 detects whether the vehicle is running or stopped (S24). Whether the vehicle is traveling or stopped can be detected by detection values of the sensors of the traveling meter and the navigation unit 17 or the like. When the processing unit 13 detects that the vehicle is traveling (S24: vehicle traveling detection), it detects whether or not a voice selection point has been selected (S25). Even if the playback button 23a is touched to select a video selection point while the vehicle is running, the processing unit 13 does not accept the above selection (NO in S25), and the voice is selected by touching the video display area 21b. Accept point selection only. When the audio selection point is selected (YES in S25: audio selection point input means), the processing unit 13 reproduces AV content from the selected audio selection point (S26: reproduction control means).

  On the other hand, when the processing unit 13 detects that the vehicle is stopped (S24: vehicle stop detection), the processing unit 13 detects whether or not a video selection point is selected (S27). Even if the video display area 21b is touched to select the audio selection point while the vehicle is stopped, the processing unit 13 does not accept the selection (NO in S27), and the video is selected by touching the playback button 23a. Accept point selection only. When the video selection point is selected (YES in S27: video selection point input means), the processing unit 13 plays AV content from the selected video selection point (S28: playback control means). As described above, there is no problem even if you watch the screen while stopped, so only the video selection point was selected, but when it is stopped, it can be played by selecting the audio selection point along with the selection of the video selection point. Also good. It is considered that operability is improved by enabling selection of playback points from both video and audio.

  As described above, according to this embodiment, it is possible to select a playback point by fast-forwarding or the like without gazing at the display screen of the AV playback device. It can be operated without any problems.

  As described above, the AV playback apparatus according to the present invention can perform a fast playback / fast reverse operation of AV content or the like at a steady playback speed based on a sound that is played back at a confirmation voice playback speed smaller than the high-speed video playback speed. Therefore, it is possible to easily select a desired playback point without paying attention to the video screen, and it is useful as an AV playback device as an in-vehicle device.
