Abstract

<P>PROBLEM TO BE SOLVED: To give three functions to one key, and also to realize speedier operation after shifting to a double-speed toggle mode. <P>SOLUTION: In an information reproducing device which uses a single forward direction key 13g as both a fast forward reproduction key and a skip forward search key in common and also uses a single backward direction key 13h as both a quick reverse reproduction key and a rearward search key in common, in a normal reproduction mode, a control part 18 controls switching between the functions of the forward direction key 13g and those of the backward direction key 13h by discriminating the corresponding direction key by a push time length, and also controls switching between the change-over modes of the reproduction speed in a double-speed toggle mode such as fast-forward reproduction or quick-reverse reproduction by discriminating the same direction key by a push-time length. That is, a single forward direction key 13g or the backward direction key 13h has the three functions of a function of shifting to a double-speed toggle mode, a function of shifting to the skip search mode, and a function of selecting a change-over mode of the reproduction speed in the double-speed toggle mode. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an information reproducing apparatus such as an optical disk apparatus. More specifically, the present invention combines a fast-forward reproduction key and a skip forward search key with one forward direction key, and a fast reverse reproduction key and a skip backward search key. Relates to an information reproducing apparatus which is also used as one reverse direction key.

  Conventionally, various devices have been proposed in which one key has two functions.

  For example, when the pressing time of the music selection operation key is shorter than an arbitrary fixed time, either the skip mode state or the manual search mode state is selected and set by the mode selection means, and the music selection operation key pressing time is arbitrary. A compact disc player has been proposed in which the mode selection means selects and sets the other of the skip mode state or the manual search mode state when the time is longer than a certain time (see, for example, Patent Document 1).

In addition, there has been proposed an optical disc player configured to perform a time skip of, for example, 5 minutes by pressing a fast reverse key or a fast forward key for a predetermined time (or continuously pressing twice) (for example, Patent Documents). 2).
JP-A-61-271660 JP-A-9-190674

  Thus, it has been conventionally performed to give two functions to one key, but it has not been conventionally performed to give three functions to one key. This is because the operation may become complicated by giving many functions to one key.

  On the other hand, in an information reproducing apparatus such as an optical disk apparatus or a video cassette recorder, a fast forward reproduction key and a skip forward search key are used as one forward direction key, and a fast reverse reproduction key and a skip backward search key are backwardly moved by one. It has already been done with the direction key.

  In this case, for example, when the forward direction key is pressed and held for a long time, the mode shifts to the double speed toggle mode, which is fast-forward playback, and when the forward direction key is pressed once, the mode is shifted to the skip search mode. This also applies to the reverse direction key.

  Furthermore, if the playback speed is to be changed after shifting to the double speed toggle mode by long-pressing the forward direction key, it is necessary to press and hold the forward direction key again. In other words, if you select the double speed toggle mode and want to change its playback speed, the operation is `` long press → release → long press '', and the double speed change operation after shifting to the double speed toggle mode is an annoying operation that takes time. It was.

  The present invention was devised to solve such problems. The purpose of the present invention is to provide a single key with three functions and to perform speed switching operation more quickly after shifting to the double speed toggle mode. An information reproducing apparatus is provided.

  The information reproducing apparatus of the present invention uses both the fast forward reproduction key and the skip forward search key as one forward direction key, and also uses the fast reverse reproduction key and the skip backward search key as one backward direction key. In the playback device, in the normal playback mode, the switching of the key function of the forward direction key or the backward direction key is discriminated based on the length of time for which the direction key is pressed, and in the double speed toggle mode such as fast forward playback or fast reverse playback. A playback control unit that discriminates and switches the playback speed switching mode by the length of time the same direction key is pressed, and the function of shifting the single direction key to the double speed toggle mode and the skip search mode. And a playback speed switching mode selection function in the double speed toggle mode.

  Specifically, in the normal playback mode, the playback control unit shifts to the double speed toggle mode when the direction key is pressed for a long time, and shifts to the skip search mode when the direction key is pressed once. In the double speed toggle mode, when the direction key is held down for a long time, continuous speed control is performed to increase the speed one step at a time when the predetermined time elapses. Single-speed control is performed to increase the speed by one step each time the button is pressed.

  That is, when the mode is shifted to the double-speed toggle mode, the normal-speed fast-forward playback is normally performed. Therefore, when the user wants to proceed further, the user can repeatedly press the forward direction key repeatedly, for example, 4 × speed, 8 × speed, 16 × speed, 32 × speed, 64 × speed, 100 × speed, etc. Can be increased to the maximum speed at once. On the other hand, if you want to move forward a little, press and hold the forward direction key. As a result, the playback speed sequentially increases, for example, 4 × speed, 8 × speed, 16 × speed,... Every time a predetermined time (for example, 1 second) elapses. Long press can be stopped and fast-forwarding to a desired position can be performed. This also applies to the reverse direction key that serves as both the fast reverse playback key and the skip backward search key.

  On the other hand, if the direction key is not pressed for a certain time (for example, 0.5 to 1 second) after the transition from the normal playback mode to the double speed toggle mode, the playback control unit Return the function to the normal playback mode again. That is, if the user does not operate the key for a certain period of time even after shifting to the double-speed toggle mode, it can be determined that the willingness to perform double-speed playback has been lost, so in this case, the direction key function is set to the normal playback state, That is, it returns to the selection input waiting state for selecting the double speed toggle mode or the skip search mode.

  In this case, the predetermined time is set to a relatively long first time (for example, 2 to 3 seconds) immediately after the transition from the normal playback mode to the double speed toggle mode, and the key operation is performed first after the transition to the double speed toggle mode. After the break, the second time (0.5 to 1 second or the like) shorter than the first time may be set. That is, at the point of time when the direction key is pressed and shifted to the double speed toggle mode, the user may consider whether to select the speed switching mode of the continuous speed control or the single shot speed control while viewing the screen. . For this reason, in order to ensure a certain amount of time to think about, when the directional key is pressed and shifted to the double speed toggle mode, the time until the directional key function is returned to the normal playback state is relatively long. Time. On the other hand, after the user decides the speed switching mode and performs the key operation, it is unlikely that the key operation interval will be widened. In this case, the function of the direction key is The time until returning to the state is a relatively short second time.

  By the way, if the direction key is pressed for a long time after shifting to the double speed toggle mode, the speed is continuously increased by one step every time a predetermined time (for example, 1 second) elapses. Although the speed control is performed, when the user continues to press and hold, the speed change may be accelerated by controlling so that the predetermined time is gradually shortened as the time of pressing the direction key becomes longer. If the user keeps pressing for a long time, it is considered that there is an intention to quickly increase to the maximum speed, for example, 100 times, as in the case of single pressing. In this case, the playback speed is increased at an accelerated rate, Control to reach maximum speed quickly. Such control enables control suitable for the user's intention.

  In addition, the playback control unit releases the long press within a preset third time (for example, 5 seconds) after the double speed reaches the maximum speed by long pressing the direction key in the double speed toggle mode. In this case, the direction key function is returned to the normal playback mode again while maintaining the maximum speed double speed toggle state, and the long press is released after the third time (5 seconds, etc.) has elapsed. Alternatively, the screen may be changed from the double speed toggle mode to the normal playback mode, and the direction key function may be controlled to return to the normal playback mode again. That is, after the double speed reaches the maximum speed by long pressing of the direction key in the double speed toggle mode, the long press is released within the preset third time (5 seconds or the like). Since it is thought that there was an intention to bring it to the maximum speed, in this case, even if the long press is released, the maximum speed, for example, 100 times speed is maintained. On the other hand, if the double speed reaches the maximum speed by long-pressing the direction key in the double speed toggle mode, and the user continues to press and hold even after a preset third time (5 seconds, etc.), Therefore, in this case, when the long press is released, the double speed toggle mode is changed to the normal playback mode. Thereby, control suitable for a user's intention is attained.

  In each of the above controls, the key operation after shifting to the double speed toggle mode is a control corresponding to a single press or a long press of only the forward direction key or only the reverse direction key, but the forward direction key and the reverse direction key are changed. When used in combination, acceleration / deceleration control of fast forward playback or fast reverse playback, switching control from fast forward playback to fast reverse playback, and the like can be performed.

  That is, in the normal playback mode, the playback control unit shifts to the double speed toggle mode in one direction by long pressing one direction key, while skip search in that direction by single pressing one direction key. In the double speed toggle mode, continuous speed control is performed to increase the speed one step each time a predetermined time elapses while the key is pressed for a long time in the double speed toggle mode. , Single speed control to increase the speed by one step each time one direction key is pressed, and further, when the other direction key is pressed once in the double speed toggle mode in that direction, the speed is reduced. It is possible to control to switch to the double speed toggle mode in the reverse direction by pressing and holding the other direction key.

  In this way, in the state in which the forward direction key is pressed for a long time during the double speed toggle mode and the fast forward playback speed is set to, for example, 64 times speed, when the reverse direction key is pressed once, the playback control unit sets the fast forward playback speed to 1. Step down to 32x speed. On the other hand, when the backward direction key is pressed for a long time, fast-forward playback is stopped at that time, and immediate reverse playback is started. The fast reverse playback speed at this time is double speed. The reproduction control by such key operation is the same when the forward direction key is single-pressed or long-pressed in the state in which the reverse direction key is pressed and held in the double speed toggle mode to perform fast reverse playback.

  According to the playback control device of the present invention, it is possible to switch to either the double speed toggle mode or the skip search mode with one direction key, and the same single direction key for switching the playback speed in the double speed toggle mode. It can be performed smoothly by single or long press. Further, by using a combination of the forward direction key and the reverse direction key, acceleration / deceleration control of fast forward playback or fast reverse playback, switching control from fast forward playback to fast reverse playback, and the like can be performed smoothly.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing an electrical configuration of an information reproducing apparatus according to the present invention.

  In this embodiment, this information reproducing apparatus is applied to the DVD player 1, and the recorded information on the DVD 2 is reproduced by a key operation of the remote controller (remote controller) 13, and an image is displayed on the screen of the monitor 11 at a desired speed. It is configured to display.

  In FIG. 1, the DVD 2 is rotationally driven by a drive system motor 3. The optical pickup 4 sends information optically read from a track of the DVD 2 to the reading unit 6. The operation speed of the motor 3 and the optical pickup 4 is controlled by the servo control unit 5.

  The reading unit 6 sends the compressed video / audio data read from the DVD 2 to the separation unit 7. The separation unit 7 separates the compressed video / audio data into a compressed video data bucket and a compressed audio data bucket, and transmits the compressed video / audio data bucket to the decompression unit 8. The decompressing unit 8 decodes each of the compressed video data bucket and the compressed audio data bucket separated by the separating unit 7 and decompresses them to the original video / audio information. The reading unit 6, the separating unit 7, and the decompressing unit 8 are configured by a general decoder IC.

  The video output unit 9 converts the video data decompressed by the decompression unit 8 into an NTSC or PAL color television signal so as to be displayed on the screen of a monitor 11 such as a television, and outputs it. The audio output unit 10 sends the audio data expanded by the expansion unit 8 to the speaker 12 to emit sound.

  The remote controller 13 is provided with various operation keys (which will be described later) for operating the DVD player 1 at its key input unit. When any key is pressed, a command corresponding to this operation is provided. The signal is transmitted to the DVD player 1 side as an infrared signal. The receiving unit 14 receives an infrared signal transmitted from the remote controller 13 and sends a transmission signal to the control unit (reproduction control unit) 18 side. Reference numeral 15 in the figure denotes a timer unit for measuring various times according to the present invention, and is connected to the control unit 18. Reference numeral 17 denotes a memory for storing various data.

  The control unit 18 includes a CPU, a ROM, a RAM, and the like. The control unit 18 shifts to a mode corresponding to a command signal from the remote controller 13 and sends a control signal to the servo control unit 5 to control the drive mechanism, thereby performing normal play. Special playback (double speed toggle state) such as (playback), pause (pause), fast forward playback or fast reverse playback is executed. In addition, operation control of the reading unit 6, the separation unit 7, the decompression unit 8, and the like is performed, the recording information of the DVD 2 is read, video is displayed on the screen of the monitor 11, and sound is emitted from the speaker 12. ing.

  FIG. 2 shows various operation keys provided in the key input unit of the remote controller 13. The remote controller 13 is provided with a power key 13a for power on / off, a reproduction key 13b, a pause key 13c for pause, a stop key 13d, an up / down key 13e, and a numeric keypad 13f, as with a general remote controller. The forward direction key 13g and the reverse direction key 13h, which are features of the present invention, are provided. The forward direction key 13g is a key used both as a fast forward reproduction key and a skip forward search key, and the backward direction key 13h is a key used both as a fast reverse reproduction key and a skip backward search key.

  Next, an operation during normal playback of the DVD player 1 having the above configuration will be described.

  After the user sets the DVD 2, when the user operates the power key 13a with the key input unit of the remote controller 13 and then operates the reproduction key 13b, the control unit 18 starts the operation of the drive system and the reading unit 6 In response, a read start command is sent. When the recording information of the track is read by the optical pickup 4 as the DVD 2 rotates, the compressed video / audio data is sent from the reading unit 6 to the separation unit 7. The separating unit 7 receives the compressed video / audio data, separates the compressed video data bucket and the compressed audio data bucket, and transmits them to the decompressing unit 8.

  The decompression unit 8 decodes the compressed video data bucket and the compressed audio data bucket, decompresses them to the original video and audio, and sends the video data to the video output unit 9 and the audio data to the audio output unit 10, respectively. Then, the video data of the video output unit 9 is sent to the monitor 11 side, and the audio data of the audio output unit 10 is supplied to the speaker 12 side. As a result, the reproduced video is displayed as a moving image on the screen of the monitor 11, and sound is emitted from the speaker 12.

  Next, examples of various reproduction operations when the forward direction key 13g is pressed during normal reproduction will be described. Note that the reproduction operation when the reverse direction key 13h is pressed is the same as the operation of the reverse direction key 13h, which will be described below, as described below. Is omitted.

  The first embodiment is the most basic reproduction operation according to the present invention. This will be described below with reference to the flowchart shown in FIG.

  In the normal playback mode, the control unit 18 constantly monitors whether or not the forward direction key 13g is pressed (step S1), and if pressed, the pressed state is long pressed (for example, 1 second). Or a single press (step S2). As a result, when it is a single push (when it is determined No in step S2), the process proceeds to step S3 to shift from the normal playback mode to the skip forward search mode. Here, since the skip search mode (including both the front side and the rear side) is a well-known mode, description thereof is omitted here.

  On the other hand, if the forward direction key 13g has been pressed for a long time (if determined Yes in step S2), the normal playback mode is shifted to the double speed toggle mode that is fast forward playback at that time (step S4).

  Then, after the transition to the double speed toggle mode, it is monitored whether or not the same forward direction key 13g is pressed again for a certain time such as 1 second (step S5, step S6). As a result, if the forward direction key 13g is not pressed for a certain period of time (if determined Yes in step S5), the playback mode is changed from the double speed toggle mode to the normal playback mode again, and the forward direction The function of the key 13g is returned to the state in the first normal reproduction mode (that is, the selection waiting state for selecting the double speed toggle mode or the skip search mode) (step S7), and the process returns to step S1. That is, if the user does not operate the forward direction key 13g for a certain period of time even after the transition to the double speed toggle mode, it can be determined that the willingness to perform the double speed reproduction has been lost. In this case, the function of the forward direction key 13g is Return to the playback mode. However, even when the forward direction key 13g is not pressed within a certain time, the double speed toggle mode may be maintained as it is.

  On the other hand, after the transition to the double speed toggle mode, when the forward direction key 13g is pressed again within a predetermined time (when determined Yes in step S6), the pressed state is long pressed (for example, 1 second or the like). ) Or single press (step S8).

  As a result, if it is a long press (when it is determined Yes in step S8), one step each time a predetermined time such as 1 second elapses while the forward direction key 13g is being pressed long. Continuous speed control for sequentially increasing the speed is performed (step S9). That is, when the mode is shifted to the double-speed toggle mode, the normal-speed fast-forward playback is normally performed. Therefore, when the subsequent long press continues for 1 second, it is 4x speed, when it continues for 1 second, it is 8x speed, when it continues for 1 second, it is 16x speed, and so on. Go up. Therefore, when the user wants to proceed a little further, the user gradually increases the 4 × speed, 8 × speed, 16 × speed,... By pressing and holding the forward direction key 13g. The long press can be stopped at any point, and fast-forwarding can be performed to a desired position.

  On the other hand, if it is determined in step S8 that it is single-pressed (if it is determined No), single-speed control is performed to increase the speed one step each time the forward direction key 13g is single-pressed (step S10). That is, when the mode is shifted to the double-speed toggle mode, the normal-speed fast-forward playback is normally performed. Therefore, when the user wants to proceed further, the user can press the forward direction key repeatedly to repeat the playback speed at once, such as 4 × speed, 8 × speed, 16 × speed, 32 × speed, 64 × speed, or 100 × speed. The maximum speed (100 times speed) can be increased. In order to exit the double speed toggle mode, the stop key 13c, the playback key 13b, etc. may be pressed.

  In the first embodiment, the fixed time in step S5 is described as being fixed at, for example, 1 second. However, in the second embodiment, a plurality (two types here) of the fixed time are set.

  In other words, when the forward direction key 13g is pressed for a long time to shift to the double speed toggle mode, the user may consider whether to select a speed switching mode of continuous speed control or single speed control while viewing the screen. There is. For this reason, in order to ensure a certain amount of time to be considered, when the forward direction key 13g is pressed and shifted to the double speed toggle mode, the time until the function of the forward direction key 13g is returned to the normal playback state is A relatively long first time (for example, 2 to 3 seconds) is set. On the other hand, after the user decides the speed switching mode and performs the key operation, it is unlikely that the key operation interval will increase. In this case, the function of the forward direction key 13g is normally reproduced. The time to return to the hour state is set to a relatively short second time (for example, 0.5 to 1 second).

  That is, the second embodiment is different from the first embodiment only in the process of step S5 shown in FIG. 3, and here, referring to the flowchart of FIG. Only explained. However, the description will be given using the step numbers shown in FIG. 3 if necessary.

  When the control unit 18 shifts to the double speed toggle mode in step S4, the control unit 18 determines whether or not the next key operation to be operated is the first key operation after the shift (step S5-1). And when it is the first key operation (when it is judged as Yes at Step S5-1), a fixed time is set to the 1st time (2-3 seconds etc.), and after shifting to double speed toggle mode, It is monitored whether or not the same forward direction key 13g is pressed again during the first time (steps S5-2 and S6). Subsequent processing is processing after step S8 of the first embodiment.

  On the other hand, after the transition to the double speed toggle mode in step S4, if the next key operation to be operated is not the first key operation after the transition (when determined No in step S5-1), the predetermined time is set to the second time. After the transition to the double speed toggle mode, it is monitored whether or not the same forward direction key 13g is pressed again during this second time (step S5-). 3, Step S6). Subsequent processing is processing after step S8 of the first embodiment.

  In the first embodiment, when the forward direction key 13g is pressed for a long time after shifting to the double speed toggle mode, one step is performed every time a predetermined time (for example, 1 second) elapses while the key is pressed. Continuous speed control is performed to increase the speed one by one. However, if the user keeps pressing for a long time, it is considered that there is an intention to increase the speed to the maximum speed, for example, 100 times as fast as the single press. Therefore, in the third embodiment, when the user continues to press and hold the forward direction key 13g after shifting to the double speed toggle mode, the longer the time the forward direction key 13g is pressed, the longer the predetermined time (for example, 1 second). ) Is gradually shortened to increase the speed change, and the fast-forward playback speed is accelerated to increase so that the maximum speed is reached quickly.

  FIG. 5 is a graph showing the relationship between the long press time and the speed change when the forward direction key 13g is long pressed. The figure (a) is a graph when the change of the double speed is 7 stages of 2 times, 4 times, 8 times, 16 times, 32 times, 64 times, and 100 times, and (b) shows the change of the speed. It is a graph at the time of changing linearly.

  As described above, in the third embodiment, the fast-forward playback speed is set to be accelerated as the long press time increases. Such control enables control in accordance with the user's intention.

  In the fourth embodiment, after the double speed reaches the maximum speed by long pressing the forward direction key 13g in the double speed toggle mode, the long press is released within a preset third time (for example, 5 seconds). This is an example in which the subsequent processing differs depending on whether the long press is released after the third time has elapsed. Hereinafter, description will be given with reference to the flowchart shown in FIG.

  That is, the control unit 18 shifts to the double speed toggle mode by long pressing the forward direction key 13g in the normal reproduction mode, and then presses the forward direction key 13g again (when it is determined Yes in step S21). While the forward direction key 13g is being pressed for a long time, continuous speed control is performed to increase the speed one step at a time every time a predetermined time such as 1 second elapses (step S22). Further, the control unit 18 monitors whether or not the long press is released within a preset third time after the double speed reaches the maximum speed by the long press of the forward direction key 13g (step S23 to step S23). S26). As a result, when the long press is released within the preset third time (when No is determined in Step S24 and Yes is determined in Step S25), the double speed toggle state of the maximum speed is maintained. Then, the function of the forward direction key 13g is again returned to the state in the normal reproduction mode, that is, the selection waiting state for selecting the double speed toggle mode or the skip search mode (step S27).

  On the other hand, if the long press is released after the preset third time has elapsed (Yes in Step S24, Yes in Step S26), the playback mode is changed from the double speed toggle mode to the normal playback mode. At the same time, the function of the forward direction key 13g is again returned to the state in the normal reproduction mode, that is, the selection input waiting state for selecting the double speed toggle mode or the skip search mode (step S28).

  That is, when the double speed reaches the maximum speed by long pressing the forward direction key 13g in the double speed toggle mode, the long press is released within the preset third time. In this case, even if the long press is released, the maximum speed, for example, 100 times speed is maintained. On the other hand, when the double speed reaches the maximum speed by long pressing of the forward direction key 13g in the double speed toggle mode, and the user continues to press and hold even after a preset third time, the user presses the screen. Since it is considered that the release timing is planned while watching, in this case, when the long press is released, the mode is changed from the double speed toggle mode to the normal playback mode. Thereby, control suitable for a user's intention is attained.

  In the control of each of the first to fourth embodiments, the key operation after shifting to the double speed toggle mode is only the forward direction key 13g or the reverse direction key 13h (however, the description of the reverse direction key 13h is omitted). However, in the fifth embodiment, acceleration / deceleration control of fast forward playback or fast reverse playback is achieved by using the forward direction key 13g and the reverse direction key 13h in combination. In this embodiment, an immediate switching control from fast forward playback to fast reverse playback can be performed. The process from the normal playback mode to the double speed toggle mode and then to the single speed control by single pressing of the direction key, or to the continuous speed control by long pressing of the direction key is the same as in the first embodiment. In the fifth embodiment, the process from step S9 or step S10 shown in FIG. 3 will be described with reference to the flowchart shown in FIG.

  Here, in the fifth embodiment, it is assumed that the processing up to step S9 and the processing up to step S10 are both performed by operating only the forward direction key 13g.

  As a result of the processing in step S9 or step S10 being performed as described above, the control unit 18 determines whether or not the reverse direction key 13h has been pressed by the user in the state in which fast-forward playback at, for example, 64 times speed is performed as the double speed toggle mode. Is monitored (step S41). As a result, if the reverse direction key 13h is pressed, it is next determined whether the key operation is a long press or a single press (step S42). If it is single-pressed (No is determined in step S42), a deceleration process is performed to decrease the current reproduction speed by one step (step S43). For example, the speed is reduced from 64 times speed to 32 times speed.

  On the other hand, if the button is pressed for a long time (when determined Yes in step S42), the current fast forward playback is switched to the double speed toggle mode of reverse playback in the reverse direction (step S44). In other words, in this case, the fast-forward playback at 64 times speed is rapidly switched to the fast-forward playback at 2 times speed. Note that such playback control by key operation may be performed even when the forward direction key 13g is single-pressed or long-pressed in the state where the reverse direction key 13h is pressed and held in the fast-speed toggle mode to perform fast reverse playback. It is the same.
