For example, the reproduction means 30 includes a DAC (Digital Analog Converter) that digitally / analog-converts the reproduction data output from the DSP 20 and outputs an audio signal, and an amplifier circuit (AMP) that amplifies the audio signal from the DAC. , It can be configured with a speaker that outputs the audio signal amplified by this AMP as audio.
[0079] The recording means 40 is composed of, for example, SDRAM or the like, and records pack data output from the data writing unit 21C of the DSP 20. The recording means 40 includes a ring memory 41 and a queue memory 42 as a position recording means.
As shown in FIG. 4B, in the ring memory 41, a front area F and a main storage area M are allocated to data storage areas from the logical start address AFW to the logical end address ABW.
[0081] The front area F is composed of two areas FA and FB, each of which stores n pack data. Like the front region F, the rear region R is also composed of two regions RA and RB, each of which stores n pack data. Further, the main storage area M is set to a storage capacity for storing a predetermined number of m of pack data.
Further, as shown in FIG. 4C, the ring memory 41 is treated as an endless one in which the logical start address AFW and the logical end address ABW are connected, so that the front area F and the rear are adjacent to each other. It has a substantially ring-shaped logical structure in which the area R is connected by the main storage area M.
[0083] The cue memory 42 records pack data (FIG. 4A) corresponding to a cue point in response to an operation signal output by pressing the cue button 117 of the operation instruction unit 110 by a user operation. Specifically, the queue memory 42 records the pack data corresponding to the queue point and the pack data at positions before and after the pack data. Here, the terms "front and back" mean that the side of the ring memory 41 facing the logical start address AFW is the front side and the side facing the logical end address ABW is the back side.
[0084] The control means 50 controls the operation of the entire information reproduction device 1. The control means 50 is composed of a CPU (Central Processing Unit) or the like, and reads and executes a control program stored in a ROM or the like (not shown). Then, a control signal is output to each component of the information reproduction device 1, and data is input / output. Therefore, although a specific illustration is omitted, a CPU, ROM, RAM, I / O, and a bus line connecting these configurations are provided inside. As shown in FIG. 3, the control means 50 is electrically connected to each component of the operation panel 100, and based on the operation signal output from each component, the DSP 20, the reading means 10, and the operation are performed. Controls the display unit 130 and the like on the panel 100. The control means 50 includes an operation instruction recognition unit 51, a reproduction control unit 52 as a processing control means, a read control unit 53 as a read control means, and a display control unit 54.
[0085] The operation instruction recognition unit 51 detects the operation signals output from the playback status changing unit 120 and the operation instruction unit 110 of the operation panel 100, and recognizes the operation instructions corresponding to these operation signals. Then, an output signal corresponding to the operation instruction is output to each component of the control means 50.
[0086] For example, the operation instruction recognition unit 51 recognizes the operation instruction as follows.
[0087] When the operation signal output from the playback status changing unit 120 is detected, the operation instruction is recognized based on the state (ON or OFF) of the jog mode button 112A and the quick return button 115 of the operation instruction unit 110. ..
[0088] Specifically, when the jog mode button 112A is in the OFF state and the quick return button 115 is in the OFF state, the operation amount detected by the angular velocity detection unit 120A of the playback status changing unit 120 is applied. Based on this, it is recognized as an operation instruction to change the playback speed when playing back the playback data.
Further, when the jog mode button 112A is in the ON state and the quick return button 115 is in the OFF state, it is recognized as an operation instruction to stop or start the processing of the reproduced data.
Here, when the operation instruction recognition unit 51 recognizes the operation amount detected by the angular velocity detection unit 120A of the reproduction status changing unit 120, the operation instruction recognition unit 51 sets the reproduction position of the reproduction data before or after according to the operation amount. Recognize as an operation instruction to move.
Further, when the jog mode button 112A is in the ON state and the quick return button 115 is in the ON state, it is recognized as an operation instruction to read the pack data recorded in the queue memory 42.
[0092] Here, when the operation instruction recognition unit 51 recognizes the operation amount detected by the angular velocity detection unit 120A of the reproduction status changing unit 120, the reproduction position (cue point) of the reproduction data is determined according to the operation amount. Is recognized as an operation instruction to move forward or backward.
Further, when the operation signal output from the cue button 117 in the operation instruction unit 110 is detected, it is recognized as an operation instruction to register the cue point. That is, the operation instruction recognition unit 51 corresponds to the position instruction recognition means in the present invention.
[0094] The reproduction control unit 52 controls the operation of the DSP 20 and causes the DSP 20 to perform a process of making the data recorded on the optical disc reproducible. The reproduction control unit 52 includes a data write control unit 52A and a data read control unit 52B.
[0095] The data writing control unit 52A records the pack data from the DSP 20 to the recording means 40 based on a program stored in a ROM or the like (not shown) or an output signal from the operation instruction recognition unit 51. Controls the amount of writing. The data write control unit 52A includes a ring memory write control unit 52A1 and a queue memory write control unit 52A2.
[0096] The ring memory write control unit 52A1 outputs a control signal corresponding to the write address to the write address controller 21D of the DSP 20. Then, the write address controller 21D sets a predetermined write address, and the data writing unit 21C outputs the pack data generated to the ring memory 41 of the recording means 40 based on the set write address.
[0097] The cue memory write control unit 52A2 sets a cue point based on the output signal from the operation instruction recognition unit 51, and outputs a control signal corresponding to the cue point to the write address controller 21D of the DSP 20. Then, the write address controller 21D sets a predetermined write address, and the data writing unit 21C outputs the pack data corresponding to the queue point to the queue memory 42 of the recording means 40 based on the set write address. .. Further, the queue memory write control unit 52A2 outputs a control signal to the DSP 20 so that the pack data before and after the pack data corresponding to the queue point is also output to the queue memory 42.
[0098] The data read control unit 52B outputs a control signal to the DSP 20 based on a program stored in a ROM or the like (not shown) or an output signal from the operation instruction recognition unit 51. The data read control unit 52B causes the DSP 20 to read the pack data from the predetermined address of the ring memory 41, and the ring memory read control unit 52B1 to cause the DSP 20 to read the pack data from the predetermined address of the queue memory 42. It is equipped with a queue memory read control unit 51B2.
[0099] For example, the data read control unit 52B may use the output signal from the operation instruction recognition unit 51 as an output signal for changing the reproduction speed, an output signal for stopping or starting the reproduction of the reproduction data, and the reproduction data. The output signal for moving the playback position forward or backward, the output signal for reading the pack data recorded in the queue memory 42, and the output signal for registering the cue point are acquired.
[0100] When the ring memory read control unit 52B1 acquires an output signal to change the reproduction speed from the operation instruction recognition unit 51, the operation amount (rotational direction) detected by the angular velocity detection unit 120A of the reproduction status change unit 120. , Rotation speed, rotation speed), and outputs a control signal to the output speed adjustment unit 22B of DSP20. Then, the output speed adjusting unit 22B adjusts the reproduction speed according to the control signal.
[0101] That is, when the jog mode button 112A is in the OFF state and the quick return button 115 is in the OFF state, when the user or the like performs a rotation operation of the playback status changing unit 120, the rotation thereof is performed. The tone of the reproduced sound played through the speakers or headphones changes according to the speed. In the rotation operation of the outer peripheral portion 122 of the jog dial, the reproduction speed is changed according to the rotation speed, not limited to the state of the jog mode button 112 and the quick return button 115.
[0102] Here, the output signal for changing the reproduction speed is based on the acceleration / deceleration of the reproduction speed set by the speed adjustment unit 112B, in addition to the output signal based on the rotation operation of the reproduction status changing unit 120. There is. In this case, the data read control unit 52B outputs a control signal to the output speed adjustment unit 22B of the DSP 20. Then, the output speed adjusting unit 22B adjusts the rising speed of reproduction and the deceleration speed in the process of stopping reproduction according to the control signal.
[0103] Further, when the ring memory read control unit 52B1 acquires the output signal to stop and start the processing of the reproduced data from the operation instruction recognition unit 51, the ring memory read control unit 52B1 outputs the control signal to the output buffer circuit 22A. Then, the output buffer circuit 22A stops and starts the output of the reproduced data according to the control signal.
That is, the jog mode button 112A is in the ON state and the quick return button 115 is in the OFF state, and during playback of the reproduced data, a user or the like presses or touches the touch sensor 121. When this is done, the reproduction of the reproduction data is stopped. Further, when the pressing operation or the contact operation is released, the reproduction of the reproduced data is restarted. The playback / stop button 118 also stops and restarts the playback data in the same manner.
Further, when the ring memory read control unit 52B1 acquires an output signal indicating that the reproduction position of the reproduction data is moved forward or backward from the operation instruction recognition unit 51, the ring memory read control unit 52B1 causes the angular velocity detection unit 120A of the reproduction status change unit 120 to obtain the output signal. A control signal is output to the read address controller 22E of the DSP 20 according to the detected operation amount (rotation direction, rotation speed, rotation speed). Then, the data reading unit 22D of the DSP 20 reads the pack data recorded in the ring memory 41 based on the reading address set by the reading address controller 22E, and performs forward playback or reverse playback.
[0106] That is, when the reproduction of the reproduced data is stopped by the pressing operation or the contact operation of the touch sensor 121, if the rotation operation with respect to the touch sensor 121 is performed, the operation amount (rotation direction, rotation speed, The playback position of the playback data is changed before or after (the number of rotations). For example, when a forward / reverse rotation operation is performed on the touch sensor 121, the playback direction is reversed between the forward direction and the reverse direction, and onomatopoeia such as so-called scratch sounds (kyukyu, gashagasha, etc.) ) Is output.
[0107] When the queue memory read control unit 51B2 acquires an output signal to read the pack data recorded in the queue memory 42 from the operation instruction recognition unit 51, the queue memory read control unit 51B2 outputs a control signal corresponding to the read address to the read address controller 22E. To do. Then, the read address controller 22E sets the read address according to the control signal. Further, the data reading unit 22D reads the pack data from the corresponding address of the queue memory 42 based on the reading address set by the reading address controller 22E.
[0108] That is, when the jog mode button is in the ON state, the quick return button is in the ON state, and the reproduced data is being reproduced, a user or the like presses or touches the touch sensor 121. Is executed, the reproduction position of the reproduction data is changed to the cue point.
[0109] Here, when the cue memory read control unit 51B2 acquires an output signal from the operation instruction recognition unit 51 to the effect that the reproduction position of the reproduction data is moved forward or backward, the angular velocity detection unit 120A of the reproduction status change unit 120 is notified. Forward playback or reverse playback is performed according to the detected operation amount (rotation direction, rotation speed, rotation speed). That is, the pack data before or after the cue point is read from the cue memory 42, and reproduction is performed.
[0110] The reading control unit 53 controls the operation of the reading means 10 to cause the reading means 10 to read the recorded information from an appropriate position on the optical disc. Further, the reading means 10 detects the data amount of the pack data recorded in the ring memory 41 of the recording means 40, and when the data amount of the pack data becomes insufficient, in order to update new pack data. , The control signal is output to the reading means 10. That is, when the reading means 10 inputs this control signal, it moves the pickup and reads the update data from the optical disc. Then, after performing a predetermined decoding process, the read data is output to the reproduction means 30, new pack data is generated, and the data is stored in the ring memory 41.
Further, when the read control unit 53 reads the pack data from the queue memory 42 by the queue memory read control unit 51B2 of the data read control unit 52B, the read control unit 53 reads the information in the vicinity of the queue point from the optical disk. The reading means 10 is controlled so as to.
[0112] The display control unit 54 acquires subcode data sequentially output by the pack data separation unit 22C of the DSP 20, and causes the display unit 130 to perform a predetermined display. In particular, as the display control of the reproduction status display unit 132 of the display unit 130, a predetermined arithmetic process is performed based on the acquired subcode data to calculate the reproduction position data, and the reproduction position is calculated based on the reproduction position data. Display is performed at predetermined positions on the display unit 132A and the cue point position display unit 132B.
[Operation of Information Reproduction Device] Next, the operation of the information reproduction device 1 will be described with reference to FIGS. 5 and 6. FIG. 5 is a flowchart for explaining the display operation of the reproduction position and the cue point of the information reproduction device 1. FIG. 6 is a flowchart for explaining the operation of changing the reproduction status of the information reproduction device 1. In addition, in FIG. 6, as a specific example of the operation of changing the reproduction situation, a playing method of returning to a cue point during reproduction and further performing scratching at this cue point will be described. Further, it is assumed that the jog mode button 112A is in the ON state.
[0114] Here, scratch is a playing method in which the reproduction direction is repeatedly reversed in the forward direction and the reverse direction to generate an onomatopoeia called a so-called scratch sound (an onomatopoeia such as "kyukyu" or "gashagasha"). is there.
First, the display operation of the reproduction position and the cue point of the information reproduction device 1 will be described with reference to the flowcharts of FIGS. 1 to 3 and 5.
[0116] When the reading means 10 reads the information recorded on the optical disk and outputs the data signal to the DSP 20, the DSP 20 processes the input data signal reproducibly. When the processing by the DSP 20 is being executed, the display control unit 54 sequentially acquires subcode data from the pack data separation unit 22C of the DSP 20 (step S1).
[0117] After step S1, the display control unit 54 performs a predetermined arithmetic process based on the acquired subcode data to calculate the reproduction position data (step S2). As a specific example of the arithmetic processing, the following method can be adopted.
That is, the display control unit 54 calculates the total number of frames played from the playback start time of the music being played to the current elapsed track time from the acquired subcode data. Specifically, the minutes Min, seconds Sec, and the number of frames Fn, which are the time information included in the acquired subcode data, are detected, and the total number of frames N is calculated by (Equation 1) shown below.
[0119] [Number 1] N = (Min × 60 × 75) + (Sec × 75) + Fn [0120] Then, the calculated total number of frames N is divided by a predetermined coefficient K, and the remainder is the playback position data. Calculate the number A of.
[0121] Here, the coefficient K is a set value determined for each optical disc. For example, in the case of a CD, K = 135 is set from the number of frames per second of the CD 75 and the rotation speed (rotation speed) 33 RPM (0.55 rotations per second) of the analog record player.
[0122] After calculating the reproduction position data in step S2, the display control unit 54 converts the reproduction position data into the reproduction position data with reference to the so-called 12 o'clock position of the reproduction position display unit 132A (FIG. 2) of the reproduction status display unit 132. The light emitting element is turned on at the corresponding clockwise position to display the playback position (step S3). Since the reproduction position data to be calculated and processed changes sequentially during reproduction, the light emitting element in the reproduction position display unit 132A lights up so as to rotate the substantially circular virtual locus of the reproduction position display unit 132A.
Here, when the cue button 117 (FIG. 1) of the operation instruction unit 110 is pressed by a user operation, the operation instruction recognition unit 51 detects an operation signal corresponding to the pressing. Then, the operation instruction recognition unit 51 recognizes the instruction of the cue point corresponding to this operation signal (step S4).
[0124] When the operation instruction recognition unit 51 recognizes the cue point instruction in step S4, the operation instruction recognition unit 51 outputs an output signal to the display control unit 54. Then, the display control unit 54 uses the reproduction position data calculated at the timing when the output signal is detected as the cue point data (step S5).
[0125] Further, the display control unit 54 lights the light emitting element at a position in the clockwise direction corresponding to the cue point data with reference to the so-called 12 o'clock position of the cue point position display unit (FIG. 2). Display the cue point (step S6).
Next, the operation of changing the reproduction status of the information reproduction device 1 will be described with reference to the flowcharts shown in FIGS. 1, 3, and 6. Here, it is assumed that the pack data corresponding to the queue point is recorded in the queue memory 42 by step S4 or the like described above.
[0127] When the DSP 20 reproduces and processes the data signal from the reading means 10, the operation instruction recognition unit 51 of the control means 50 is pressed by the touch sensor 121 of the reproduction status changing unit 120 with a predetermined pressure by a user operation. Determine if it has been done (step S11). That is, the user performs a pressing operation on the touch sensor 121, and determines whether or not an operation signal based on this operation is detected. Here, when the pressure is not pressed by a predetermined pressure, that is, when it is determined that "No", the operation of changing the reproduction status is terminated. Therefore, the playback status of the DSP 20 continues unchanged.
[0128] If "Yes" is determined in step S11, the operation instruction recognition unit 51 further determines whether or not the quick return button 115 (FIG. 1) of the operation instruction unit 110 is in the ON state (FIG. 1). Step S12). That is, the operation instruction recognition unit 51 determines whether the change content for changing the playback status by the touch sensor 121 is the change content related to the stop or start of processing or the change content related to the change of the playback position. To judge.
[0129] In step S12, when it is determined as "Yes", that is, when it is determined that the change content of the reproduction status by the touch sensor 121 is the change content related to the change of the reproduction position, the operation instruction recognition unit 51 , The output signal to read the pack data recorded in the queue memory 42 is output to the queue memory read control unit 51B2. Then, the queue memory read control unit 51B2 outputs a control signal to the DSP 20. After that, the DSP 20 is set to stop the processing of the reproduced data and read the pack data from the queue memory 42 (step S13).
[0130] After step S13, the operation instruction recognition unit 51 acquires the operation amount detected by the angular velocity detection unit 120A of the reproduction status changing unit 120, and determines whether or not the reproduction status changing unit 120 is rotated by the user operation. Determine (step S14). Here, if it is determined as "No", the stopped state of the reproduction process in step S13 is continued, and the process proceeds to step S17.
On the other hand, when it is determined as "Yes" in step S14, the operation instruction recognition unit 51 rotates the reproduction status changing unit 120 forward (clockwise) based on the operation amount of the reproduction status changing unit 120. It is determined whether or not it is (step S15).
[0132] If "Yes" is determined in step S15, the queue memory read control unit 51B2 outputs a control signal to the output speed adjustment unit 22B of the DSP 20. Then, the DSP 20 reads the pack data recorded in the cue memory 42, detects it by the angular velocity detection unit 120A, and at a reproduction speed corresponding to the rotation speed of the reproduction status changing unit 120 recognized by the operation instruction recognition unit 51. In addition, the reproduction process is performed in the forward direction from the cue point by the amount of rotation of the reproduction status changing unit 120 (step S16).
[0133] After step S16, the operation instruction recognition unit 51 determines whether or not the pressing state of the touch sensor 121 by the user operation continues (step S17). Here, if it is determined as "Yes", the control means 50 restarts the process from step S14 again. That is, while the state in which the touch sensor 121 is pressed by the user operation continues, the steps S14 to S16 are repeatedly executed.
[0134] When the steps S14 to S16 are repeatedly performed in this way, if "No" is determined in step S15, that is, the rotation direction of the reproduction status changing unit 120 is not forward rotation. If it is determined that the rotation is reverse (counterclockwise), the queue memory read control unit 51B2 outputs a control signal to the read address controller 22E (FIG. 3) and the output speed adjustment unit 22B (FIG. 3). Then, the DSP 20 reads the pack data recorded in the queue memory 42 in the reverse direction. Further, the DSP 20 has a playback speed according to the rotation speed of the playback status changing unit 120 detected by the angular velocity detection unit 120A and recognized by the operation instruction recognition unit 51, and only the rotation amount of the playback status changing unit 120. , Perform the reproduction process in the reverse direction from the cue point (step S18).
[0135] That is, by performing forward reproduction in step S16 and reverse reproduction in step S18, onomatopoeia (onomatopoeia such as "kyukyu" and "gashagasha") called so-called scratch sounds are produced at the cue point. The resulting scratch playing technique is performed.
[0136] Further, when returning to step S12 and the operation instruction recognition unit 51 determines "No", that is, the change content of the playback status by the touch sensor 121 is the change content related to the stop or start of the process. When the determination is made, the ring memory read control unit 52B1 outputs a control signal to the output speed adjustment unit 22B (FIG. 3) of the DSP 20. Then, the DSP 20 is set by the speed adjustment unit 112B (FIG. 1) of the operation instruction unit 110, and the reproduction speed is gradually reduced to 0% according to the deceleration speed in the reproduction stop process recognized by the operation instruction recognition unit 51. And stop the process (step S19).
[0137] Similarly, after step S19, in step S17, the steps from step S14 are repeatedly carried out while the state in which the touch sensor 121 is pressed by the user operation continues. In this case, in step S16 and step S18, the ring memory read control unit 52B1 causes the DSP 20 to read the pack data recorded in the ring memory 41 and execute the reproduction process from the stop position of the process in step S19. ..
[0138] Then, when it is determined as "No" in step S17, that is, when the state in which the touch sensor 121 is pressed by the user operation is released, the reproduction control unit 52 sends the output speed adjustment unit 22B to the output speed adjustment unit 22B. Output the control signal. Then, the DSP 20 is set by the speed adjustment unit 112B (FIG. 1) of the operation instruction unit 110, and the reproduction speed is set to 100% according to the reproduction start-up speed recognized by the operation instruction recognition unit 51 for processing. Start (step S20).
Here, in step S12, when the quick return button 115 (FIG. 1) of the operation instruction unit 110 is in the ON state, the DSP 20 reads the pack data recorded in the queue memory 42 and performs a reproduction process. carry out. On the other hand, in step S12, when the quick return button 115 of the operation instruction unit 110 is in the OFF state, the DSP 20 reads the pack data recorded in the ring memory 41 and executes the process.
[Effect of the Embodiment] In the information processing apparatus 2 of the present embodiment described above, the reading means 10 for reading the information recorded on the optical disk as the recording medium and the information read by the reading means 10 are processed.

When the change instruction to change the information is recognized, the playback control unit 52 as a processing control means for changing the processing status of the DSP 20 is provided based on the processing content selected by the quick return button 115. It is a feature.
[0141] Then, in the present embodiment, the reading means 10 reads the information recorded on the optical disc and outputs the read signal. Further, the DSP 20 detects this read signal and processes it reproducibly. Then, the quick return button 115 selects at least one of the processing content related to the information processing start or processing stop and the processing content related to the change of the information reproduction position. Here, when the reproduction status change unit 120 recognizes the change instruction to change the information processing status in the DSP 20, the reproduction control unit 52 determines the DSP 20 based on the processing content selected by the quick return button 115. Change the information processing status. As a result, as a change instruction to change the processing status, the processing content related to the processing start or processing stop and the processing content related to the change of the playback position are shared and recognized by the playback status changing unit 120. The operability of the information reproduction device 1 can be improved by simplifying the members.
[0142] Here, the touch sensor 121 of the playback status changing unit 120 recognizes a change instruction to change the two playback statuses of processing start or processing stop and playback position change by pressing operation or touch operation. To do. Therefore, by operating the touch sensor 121, it is possible to execute two processes of starting or stopping the process and changing the reproduction position, and the operability of the information reproduction device 1 can be improved.
[0143] In the information processing apparatus 2 of the present embodiment, the reading means 10 for reading the information recorded on the optical disk, the DSP 20 for processing the information read by the reading means 10, and the reproduction position of the information in the DSP 20 are changed. The playback status change unit 120 that recognizes the change instruction to the effect that the information is to be played, the processing content related to the change that moves the playback position of the information before or after, and the information playback position are moved to the queue point as the preset processing start position. When the change condition setting means for setting the processing contents of both the processing contents related to the change and the change instruction for changing the reproduction position of the information are recognized by the playback status changing unit 120, the change condition setting means is set. It is characterized in that it is provided with a reproduction control unit 52 that changes the reproduction position of the DSP 10 based on the processing content.
[0144] Then, in the present embodiment, the reading means 10 reads the information recorded on the optical disk and outputs the read signal. Further, the DSP 20 detects this read signal and processes it reproducibly. Then, the change condition setting means sets both the processing content related to the change that moves the information reproduction position before or after, and the processing content related to the change that moves the information reproduction position to the preset cue point. .. Here, when the reproduction status changing unit 120 recognizes the change instruction to change the reproduction position of the information in the DSP, the reproduction control unit 52 determines the DSP 20 based on the processing content set by the change condition setting means. Change the playback position. As a result, as a change instruction to change the playback position, the processing content related to the change to move the playback position forward or backward and the processing content related to the change to move the playback position to the cue point are standardized and the playback status change unit. Since the 120 is recognized, the operation member can be simplified and the operability of the information reproduction device 1 can be improved.
[0145] Here, the change condition setting means corresponds to the jog mode button 112A and the quick return button 115. When both the jog mode button 112A and the quick return button 115 are in the ON state, the processing content related to the change of moving the playback position of the playback data to the cue point is set, and the playback status change unit 120 described later The movement of the processing position of the reproduced data to the front or the back can be changed according to the operation amount detected by the angular velocity detection unit 120A.
