The present invention relates to a data reproducing apparatus and a control method thereof, and more particularly, to a data reproducing apparatus capable of reading and reproducing data from a storage medium and a control method thereof.

In general, devices operated according to a user's command are configured to immediately perform a corresponding operation in response to a user's command input. For example, if a user selects a play key on a CD player equipped with a disc, the player sequentially plays the songs contained on the disc. If the user selects a key instructing a repeat play command while the song is being played, the song is repeatedly played. In this way, if the user wants the player to perform a desired action, the user then operates a key corresponding to the desired action.                         

1 is a block diagram of a general disc player.

The disc reproducing apparatus includes a disc drive 30 driven to read data from or write data to the disc 10, a key input unit 20 for receiving a command from a user, and a disc read out from the disc. And a display unit 40 for reproducing data and displaying them externally, and a controller 50 for controlling the disk drive 30 and the display unit 40 to perform an operation requested by a user through the key input unit 10.

In the above configuration, the user passes his intention through the key input unit 10 to the controller 50 of the system at that time, and the control unit 50 grasps the command transmitted from the key input unit 10 and the user desires. The disk drive 30 and the display unit 40 are controlled so that the operation can be performed immediately.

Meanwhile, with the development of technology for recording information on recording media, large-capacity recording media such as DCD (Digital Convergence Disk), which has a recording density of several times that of CD (Compact Disk) or DVD (Digital Video Disk), are being developed one after another. In the case of a recording medium such as DCD, a DCD player (Digital Convergence Disk Player) has been developed for playing recorded files, for example, music files.

The DCD typically has a recording capacity of 500 megabytes (MB) on a coin-sized disc, which can store approximately 100 to 150 songs of approximately four minutes.

And, like the general disc player mentioned above, the DCD player is configured to communicate the intention through key operation at that time in order to perform the operation desired by the user.

However, in such a CD player, an MP3 player, and a data player such as a DCD, it is sometimes cumbersome for a user to input a command each time in order to perform a desired operation. For example, on a disc where songs corresponding to numbers 1 through 20 are stored, the user repeatedly plays song 1 about 5 times and skips song 2 through 10 while playing the preset time. When the user wants to play the songs from No. 11 to No. 20 only once, the conventional disc player requires the user to directly select the corresponding command key each time each song is played. However, this is cumbersome because the user must convey his intention to each song even though the user has already decided on the desired playback method for all songs, and at the end of each song to determine the action for each song. Esau should focus more than necessary.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data reproducing apparatus having a command reservation function for reserving a plurality of command sets and executing the reserved commands sequentially in order to solve the above problems, and a control method thereof.

The data reproducing apparatus of the present invention for achieving the above object comprises an input unit for receiving a reservation command for the operation of the system from the user; A reservation command storage unit for sequentially storing a plurality of reservation commands inputted through the input unit; And a control unit controlling the system to execute sequentially for each of the plurality of reservation commands stored in the reservation command storage unit.

Here, the input unit is provided with a key input unit including a command reservation mode key for converting the system into the command reservation mode, the control unit from the key input unit in the state that the system is switched to the command reservation mode through the command reservation mode key When the command key signal is transmitted, the command corresponding to the command key signal is controlled to be stored in the reserved command storage unit. Meanwhile, the controller may allow the selected command to be stored in the reservation command storage unit when the reservation mode key and the command key provided at the input unit are simultaneously selected.

The input unit may include a voice input unit for inputting a reservation command by voice so that a user may reserve a command by his / her own voice.

The data reproducing apparatus further includes a reference command storing unit for storing reference commands in order to determine whether the commands stored in the reserved command storing unit are executable, and wherein the control unit stores each reference command stored in the reserved command storing unit for storing the reference command. Controls the system to execute the command if it exists in the department.

In addition, if each reservation command stored in the reservation command storage unit does not exist in the reference command storage unit, the controller determines whether there is a subsequent reservation command and determines whether to execute it accordingly. If the subsequent reservation command no longer exists, the controller controls the system to end the reservation command execution mode and return to the preset power saving management mode. Here, the control unit may control the system so that the reservation command execution mode is repeated if a subsequent reservation command no longer exists.                     

According to an aspect of the present invention, there is provided a method of controlling a data reproducing apparatus, the method including: detecting a command reservation mode switch request for receiving a command for a system operation from a user; Switching the system to a command reservation mode when the command reservation mode switch request is detected; Sequentially storing a plurality of reservation commands sequentially input in the command reservation mode; And sequentially performing each of the stored plurality of reservation commands.

The storage of the reservation command stores the reservation command in response to an input signal according to a user's key selection after a command reservation mode switch request is detected.

In addition, the plurality of reservation commands are stored in response to an input signal according to a voice input of a user.

The storing of the plurality of reserved commands may include determining whether the number of input reserved commands corresponds to the maximum number of stored reserved commands; And if it is determined that the number of the reserved command input corresponds to the maximum storage number of the reserved command, displaying the command non-reservable message.

In addition, the control method of the data reproducing apparatus further includes a step of presetting as a reference reservation command with respect to the available reservation commands.

The execution of the reservation command may include detecting whether the input reservation command exists within preset reference reservation commands; And if the input reservation command is not included among the reference reservation commands, determining that it is an error and determining whether the subsequent reservation command is executable.                     

And if there is no more reservation command waiting to be executed in the execution step of the reservation command, the step of exiting the reservation command execution mode and switching to a preset power saving management mode. On the other hand, if there are no more reserved commands to be executed, the reserved command execution mode may be repeatedly performed.

Hereinafter, a command reservation function through the DCD player to which the present invention is applied will be described.

First, a brief overview of DCD is provided to explain the DCD player.

FIG. 1 is a diagram illustrating a digital convergence disk (DDC) classified according to recording areas.

The DCD 110 is circular and has a hole 112 formed therein so that a spindle for rotating the disk can be fitted at the center thereof. Between the hole 112 and the outer periphery, the hole 112 is divided into a unique number recording area 114, a data recording area 116, and a file system recording area 118. The unique number recording area 114 of the DCD 10 records the unique number assigned to each DCD 110 to distinguish each DCD 110. In addition, the unique number recording area 114 includes identifiable information on both sides of one DCD 110 according to the characteristics of the DCD 110 which is a double-sided recordable optical recording medium. The data recording area 116 is an area where data such as music data, document data, image data, and the like are recorded, and occupies most of the recording capacity of the DCD 110. The file system recording area 118 is located near the outermost periphery of the DCD 110, and information about each file system recorded in the data recording area 116 of the DCD 110 is recorded. The file system information includes the size, name, recording date and time, recording format, directory information, and last modified date and time of the file, etc., recorded in the data recording area 116 of the DCD 110.

3 is a schematic block diagram of a DCD player 100 capable of playing the DCD shown in FIG. 2 and having a command reservation function according to the present invention.

The DCD player 100 is largely comprised of the engine 120 and the host 140. Here, the engine 120 is a DCD driver that accesses to record and read data to the DCD 110, the host 140 is connected to interface the data with the engine 120, the engine ( It transmits the control code and the recording data to the 120, and serves as a playback device for receiving and reading the data read from the DCD (110) from the engine (120). In addition, the host 140 is connected to an external device, for example, a personal computer (PC) 200 to control the engine 120 from the personal computer 200.

The engine 120 includes a spindle 121, a DCD pickup unit 122, a spindle 124, a pickup driving unit 125, an engine memory 126, an engine buffer 127, and an engine control unit 128.

The DCD pickup unit 122 writes and reads data to the DCD 110 mounted under the control of the engine controller 128. The spindle driver 124 and the pickup driver 125 drive the spindle 121 and the DCD pickup unit 122 under the control of the engine controller 128. The engine buffer 127 temporarily stores data to be recorded and read data when the engine pickup unit 122 records or reads data from the DCD 110. The engine buffer 127 may use SRAM. The engine memory 126 stores code values for various commands promised between the engine unit 120 and the host 140, and stores a program for operating the engine unit 120. In this case, the engine memory 126 may use the flash memory 126. The engine controller 128 receives a command transmitted from the host 140, and according to a program stored in the engine memory 126, the DCD pickup unit 122, the spindle driver 124, the pickup driver 125, and the engine buffer. Control 127. In addition, the engine control unit 128 includes a register unit 128-1 consisting of four registers for use in communication with the host 140.

The register section 128-1 is composed of a control register 128a, a status register 128b, a byte counter register 128c, and a data register 128d, and each register is operated as follows.

The control register 128a records function control and interface interrupt enable / disable information by the host 140, and controls the respective blocks of the engine by reading the values from the engine controller 128.

The status register 128b records and reads status information and interrupt reason information from the engine 120, and reads the information from the host 140 to perform control according to the read information.

Byte counter register 128c performs both write and read operations at host 140 and engine 120, respectively. However, the host 140 can write to the byte counter register 128c only when the set BUSY bit of the status register 128b is clear, and the set data DATA bit of the status register 128b is set. If only, read valid information is read from the byte counter register 128c. The byte counter register 128c contains a byte count for subsequent command, data, or status mode transfers.

The data register 128d may also be read and written in both the host 140 and the engine 120. However, the host 140 writes to the data register 127d while in the command and data out phases, and in the engine 120, the status and data in phases are displayed. Read data register 127d.

The host 140 includes an input unit 142 equipped with a key input unit 142a and a voice input unit 142b, a host memory 143, a USB interface 144, a liquid crystal display (LCD) 145, and an audio codec 146a. And an audio output unit 146 and a host control unit 141, each of which comprises an amplifier 146b.

The key input unit 148 is a command reservation mode key for selection, playback, recording, skipping, volume, and the like, and command commands provided for allowing a user to input a command relating to the operation of the DCD player 100 as shown in FIG. It includes.

The voice input unit 147 includes a microphone (not shown) and a voice processor (not shown) installed to receive a command from the user.

The host memory 143 stores code values for various commands promised between the host 140 and the engine 120, and programs related to operations of the engine 120 and the host 140 are stored. The flash memory 143 can be used as a storage means.

The USB interface 144 allows an external device such as the DCD player 100 and the PC 200 to interface data with each other.                     

The LCD 145 displays user identification information on the screen under the control of the host controller 141.

The audio output unit 146 outputs various voice messages such as audio data read out from the DCD 10 and internal warning sounds under the control of the host controller 141.

The host controller 141 may include a plurality of timers 141a for temporal control of the system, an OSD processor 141b for providing various character information to be displayed on the LCD 145, and a plurality of reservation commands for storing the plurality of reservation commands. Buffer 141c.

The DCD player includes the above components, and a process of transmitting a command from the host 140 to the engine 120 will be described with reference to FIG. 4.

First, the host 140 checks the BUSY bit in the status register 127b of the engine 120 before issuing a command. At this time, when the busy bit is clear, the engine 120 determines that the command can be received. If the busy bit is set, the host 140 transmits to the engine 120. Clear the busy bit by sending a command to clear the busy bit. In this way, if the busy bit is cleared, the host 140 writes a reset byte count pointer function code into the control register 128a so as to be an address alignment. Host 140 then writes the size of the command packet to byte counter register 128c, then writes a " start command funcrion code " to control register 128a and sets the IRQ bit ( M2). Then, the engine 120 reads the size of the command packet from the byte count register 128c, processes it as an error if the size of the command packet is zero or more than the maximum size, and otherwise receives a command, that is, the command mode. The state transitions to M3.

When the IRQ bit of the control register 128a is set by the host 140, the engine unit 120 reads the byte count register 128c and switches from the idle mode M1 to the command mode M3. Is as follows. When switching from the idle mode M1 to the command mode M3, the engine unit 120 sets the control / data bits of the contents of the status register 128b and read / write (RD / WR). Clear the bit. Next, the engine unit 120 sets the IRQ bit. When the IRQ bit is set by the engine unit 120, the host 140 writes a command packet byte to the data register 128d of the engine unit 120. When the instruction packet byte is written to the data register 128d, the engine unit 120 enters the instruction mode M3 for executing the instruction by clearing the data bit of the status register 128b.

A write or read operation is performed in the data mode M4 in accordance with the contents of the command in the command mode M3. In the case of a read operation, the host 140 reads the data register 128d. On the other hand, in the recording mode, the host 140 writes data to the data register 128d. When data mode M4 is complete | finished, it progresses to status mode M5.

In the status mode M5, the host 140 checks the status of the current engine unit 120 by reading the status register 128b. If the current status is confirmed, read the byte counter register 128c and the data register 128d again to check the contents to be transmitted, then terminate the command and enter the idle mode (M1) again. At this time, if a command is input from the outside, the process is repeated.

In the above, the process in which the command is transmitted from the host 140 to the engine 120 has been described. Hereinafter, the command reservation function according to the present invention in the DCD player shown in FIG. 2 will be described with reference to the flowchart of FIG. 5.

First, when the DCD 110 is inserted into the DCD player 100, the engine 120 notifies the host 140 of the insertion of the new DCD 110. Then, the host 140 detects the insertion of the disk 110 from the signal transmitted from the engine 120 and requests and obtains information of the file system recorded in the DCD 110 from the engine 120. The host 140 then displays the file system information on the LCD 145 as shown in Fig. 6. Of course, when the data recording DCD is mounted, other information is displayed on the LCD 145 as well.

If there is a command reservation request from the user in the state in which the file system information of the inserted disk 110 is displayed on the LCD 145 (S10), that is, the reservation key 142a-1 of the key input unit 142a is entered by the user. When a preset voice, such as 'reserving command', is selected or input as a voice through the voice input unit 142b, the host controller 141 switches the system to a mode for receiving a user's command (S20). When the command is subsequently input through the key input unit 142a or the voice input unit 142b (S31), the host controller 141 sequentially stores the commands input to the buffer 141c provided therein (S33). )).

Here is an example of the input of the reservation command through the key input unit.

When the user wants to listen to a part of the first to fourth songs of the disc, and wants to reserve a command when the fifth song is to be repeated five times, first, the files are listed in the LCD window as shown in FIG. The reservation key 142a-1 of 142a is selected. Then, as shown in FIG. 7, the LCD 145 window displays the letter 'reservation', indicating that the command can be reserved. After that, the user selects the skip key (▶ |) while selecting bars are positioned from the first to the fourth songs through the selection keys (▲ / ▼). The buffer 141c stores a command to skip the first to fourth songs. Then, the user places the selection bar on song 5 through the selection keys (▲ / ▼) and selects the repeat key (⊃). Then, the input window 145a pops up on the LCD 145 window as shown in FIG. 8 so that the user can input the repetition number. At this time, if the user inputs 5 as the number of repetitions through the selection key (▲ / ▼), a command is stored in the buffer 141c that the fifth song is repeated five times.

After such reservation commands are stored in the buffer 141c (S30), if the key input signal is no longer detected until reaching the set time (S40), a plurality of stored in the buffer 141c The control command is transmitted to the register unit 128-1 of the engine unit 120 so as to be sequentially executed according to the input order of the reservation commands (S50). When all of the plurality of reservation commands stored in the buffer 141c have been executed, the reservation command execution mode is terminated, and the system is controlled to switch to the preset power management mode (S60).

If, in the above operation, the host control unit 141 reaches or exceeds the maximum number of reserved command storages provided with the number of reserved command inputs of the user (S33a), a non-reserving message is displayed on the LCD (S33b). Then, the system is controlled so that the reserved commands are executed sequentially according to the input order (S50). Of course, when the maximum number of inputs of the reservation command is stored, it is possible to immediately execute the reservation command without displaying a message.

In addition, during the above operation, the host controller 141 may immediately start the execution of the reservation command when there is a request for performing the reservation command from the user without waiting for a setting time. For example, if the user selects the reservation key 142a-1 and then reserves the commands, and then selects the reservation key again to select the reservation completion (S42a), the stored reservation commands are immediately executed.

In another example of inputting a reservation command, when another key is simultaneously selected while the reservation key 142a-1 is pressed, a command corresponding to the selected key may be stored in the buffer 141c provided. Similarly, the host controller 141 may determine only the voice input in the state where the reservation key 142a-1 is pressed as a reservation command to be stored in the buffer 141c.

On the other hand, the host controller pre-stores the executable reserved commands as reference commands in the host memory 143 or another storage means, and does the reserved waiting command stored in the buffer 141c exist in the previously stored reference commands? After determining whether or not the command is executable (S51), it can be performed (S52). If the reservation command stored in the buffer does not exist in the reference commands, the host controller 141 determines whether the subsequent reservation command can be executed as before (54). If it is determined that the command is executable, the command is executed (53a).

The digital convergence disc player of the present invention as described above allows the user to input commands for the separate operations of the player at once, and processes them to be automatically performed sequentially for such command inputs. There is no need to instruct commands for the player's division action.

In the above description, the command reservation function according to the present invention has been described as an example of a digital converged disc player. However, the present invention is not limited to the digital converged disc, and it is well known that the present invention can be applied to another reproducing apparatus capable of playing and recording data. It will be true.

The data reproducing apparatus and the control method according to the present invention as described above do not need to input a command for each operation of the device in order for a user to perform a desired function, the hassle of having to input a command for every operation In this way, the user does not need to concentrate more than necessary to input a command for each division operation.
