Abstract

PURPOSE: A method for controlling a digital audio station is provided to conveniently reproduce audio data by removing frequent reinput processes of a program according to exchange of disks. CONSTITUTION: It is judged whether a first mode reproducing signal by a manual operation of a user is generated or a second mode reproducing signal by a programming defining a specific execution mode and execution list is generated. According to mode conversion, header information of audio data inserted or stored into a sound player is read to judge whether the audio data are changed(S285). In the case of a mode executing an audio data list in a specific execution mode, a database is updated with the changed audio data list based on execution time and execution mode(S286-S287). In the case of a mode executing by audio data extensions, the database is updated by audio data extensions based on execution time and execution mode. Audio data are reproduced in order of being programmed by lists or extensions.

Description

Method for controlling a digital audio station

The present invention relates to a control method of a digital audio station, and more particularly, to automatically update header information generated in response to a change and a change of a medium storing audio data in a database, to prevent reprogramming, and to proceed to another specific mode. The present invention relates to a control method of a digital audio station in which a reproduction is performed to a silent region of an execution section in an arbitrary mode being executed at the time of occurrence, and at the same time, reproduction is performed after the silent region at the end of a specific mode to maintain continuity.

Recently, a sound reproducing apparatus incorporating a CD player, an MP3 player, a radio, and the like as one is preferred, and various reproducing sound reproducing apparatuses have been manufactured. In the operation of the integrated sound reproducing apparatus, each reproducing apparatus that performs its own function has an identifier mode for identifying the execution mode, so that the reproducing apparatus finally executed by recording of the identifier mode can be detected. . That is, when the user executes the previous execution mode by storing the identifier mode immediately executed in the memory, the user can execute the previous execution mode by retrieving the identifier mode from the memory and driving the matching playback device. It is a known fact.

However, in the conventional sound reproducing apparatus, when the mode is changed by a user's operation, in order to execute the previously executed execution mode, the user must perform key input to switch to the previous mode. In addition, when the previous mode is executed, there is a problem that the playback cannot be executed from the previously played position because the initialization is performed from the first position.

Therefore, recently, a programmable sound reproducing apparatus capable of randomly executing the driving of each sound reproducing apparatus has been proposed. However, even in this case, once programmed data has a disadvantage of being limited to a disc such as a CD, an MP3 or the like that is currently inserted and executed. In other words, when a disc such as a CD or an MP3 that stores audio data is replaced, the programmed data becomes meaningless. Accordingly, the user has an inconvenience of having to re-enter programming such as selecting a desired song arbitrarily.

In addition, for example, if the MP3 player is executed while the CD player is being played to play the songs contained on the CD, the MP3 file is played at the same time as pressing the operation button of the MP3 player. The sound was suddenly cut off, and there was a disadvantage in that noise and unpleasant noise were output due to the mode change.

Accordingly, an object of the present invention is to update the database by listing the disk header information in the execution time area of the pre-programmed data each time the user replaces with a new disk in order to prevent re-entry of programming, as well as update the database. The present invention provides a control method of a digital audio station that automatically performs a playback function by updating its data to a database.

In addition, another object of the present invention is to search and determine the silent region of any mode currently being executed when an execution signal for advancing to another mode is generated during execution of any mode to maintain continuity of execution intervals in any mode. The present invention provides a control method of a digital audio station that executes up to the silent region and at the same time completes another mode after the silent region is executed.

The present invention for achieving the above object of the present invention relates to a control method of a digital audio station having at least one sound reproducing apparatus, the control method of the digital audio station of the present invention, the system initialization of the digital audio station Determining whether a second mode playback signal is generated by a user's manual operation or a programming defining a specific execution mode and a execution list in the sound reproducing apparatus; Mode switching to play a specific execution mode in a first mode when there is a manual operation by the user, and to play a specific execution mode in a second mode when the second mode playback signal is generated during execution of the first mode. Performing; Determining whether audio data has been changed by reading header information of audio data inserted or stored in each sound reproducing apparatus according to the mode change; In the case where the audio data is changed, in the case where the audio data list is executed in a specific execution mode to perform selective playback of the sound reproducing apparatus and the audio data list, the existing audio is based on the execution time and the execution mode. If the data list is updated with the changed audio data list or the mode is executed by extension to perform selective playback of the same extension list on the audio playback device and audio data, the audio is based on the execution time and execution mode. Performing any one of a control process of updating the database for each data extension; Performing reproduction in a programmed order for each list or extension based on the updated database; And determining whether or not the execution of the second mode is completed, and continuously performing playback after the end point of the first mode when the second mode is completed.

At this time, the first mode is preferably programmable so that selective reproduction can be performed in the corresponding list and time.

In addition, in the step of performing the reproducing by the programming, when switching from any execution mode to a specific execution mode, it is preferable to load the specific execution mode header information to be executed next before the execution of any execution mode previously executed. More preferable.

The updating of the audio data list in a database may include: determining whether a corresponding sound reproducing apparatus is open; Comparing the header information read in the initialization process with the header information according to the newly input disc reading when the sound reproducing apparatus is opened; And updating only the header information of the execution list in the database based on the execution time and the execution mode when the header information of the newly input disk is different from the existing header information. The updating of the same extension-specific list in the database in the audio data may include: determining whether a corresponding sound reproducing apparatus is opened; Comparing the header and extension information read in the initialization process with the header and extension information according to the newly input disc reading when the sound reproducing apparatus is opened; When the header and extension information of the newly input disk are different from the existing header and extension information, updating only the extension information of the execution list on the basis of the execution time and the execution mode is performed. Here, after updating the database, if a specific execution list is set in a specific execution mode, it may be desirable to proceed with the process of creating the execution list and reproducing the list in order.

On the other hand, it is preferable to digitize and store audio data for a predetermined time in the reproducing step in the specific execution mode. At this time, the data is read out through addressing of 32MB or 64MB of internal flash memory or 32MB / 64MB MMC (Multi Media Card) memory which can be additionally installed as a medium for digitizing and storing the audio data. The method may further include: reading the stored digital audio data and searching for a silent region when there is a mode change request signal from the arbitrary execution mode to a specific execution mode; Executing the silent region until the silent region is found; Reproducing the input specific execution mode; And when the reproduction of the specific execution mode is terminated by a programmed sequence or by a user's manual operation, continuously executing the arbitrary execution mode after the silent region. In this case, the searching of the silent region may include: transmitting the stored digital audio data to a CPU and comparing the reference data with reference data by an executed search program; Outputting a control signal corresponding to a search result when the silent region is found by the search, and temporarily designating the silent region by comparing with a preset sound or noise level when there is no silent region; And controlling the CPU to control the control signal corresponding to the search result and the control signal designated as the silent area and to stop the output before the silent area.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a control block diagram schematically showing a configuration of a digital audio station according to an embodiment of the present invention. The digital audio station of the present invention is largely composed of a CD player, a radio, and an MP3 player. Of course, it is well known that other sound reproducing apparatus can be added thereto.

Referring first to Fig. 1, a digital audio station of the present invention basically includes a RAM (RAM) 10, a ROM (ROM) 12, and a CPU 14 interconnected to a bus. The CPU 14 functions as a controller and controls the overall operation of the digital audio station. The RAM 10 is provided for temporarily storing digital audio data of a playback apparatus currently being executed for a predetermined time and for storing various task data. Also, the header information of the sound reproducing apparatus to be executed next by programming is temporarily stored. The ROM 12 not only stores a program for controlling the operation of the digital audio station but also stores a program for searching for the silent region to be achieved in the present invention. The RAM 10 preferably uses a flash memory, and separately prepares a cache memory (not shown) for storing header information or is embedded in the CPU 14 to prevent execution delay of the execution mode to be executed next. It would be more desirable to use cache memory.

The key input unit 16 is composed of a plurality of keys that support user operations to perform settings related to time, alarm time, time sound, alarm sound, MP3 file playback repeat section, schedule, radio, and recording time setting. Specifically, alarm setting key (ALRM SET), alarm sound setting key (ALRM SOUND), sleep time setting key (SLIP TIMER), broadcast receiving key (AM / FM), MP3 selection key (MP3), CD selection key (CD) , Select key (REW), Enter key (ENTER), Select key (FF), Stop key (STOP), Repeat key (REPEAT), Equalizer key (EQ), Volume control key (VOL), Relax key (RELAX) , And hot keys (HOT). The RELAX refers to a program key for pre-programming execution modes and order of execution lists of CDs, MP3s, and radios according to user settings, and may be pre-stored in a large storage device to execute them. In addition, the hot key (HOT) refers to a program key that searches for an extension corresponding to the execution time and performs playback in the programmed order. That is, when the relaxation mode corresponding to the relaxation key is performed by a manual operation or a program by a user, or when the hot mode corresponding to the hot key is executed, playback is performed in the order of the programmed list or the list by extension. In this embodiment, the key input unit 16 is formed by dividing the first mode and the second mode, which will be described later. Hereinafter, since each function of the key and its setting process may be performed by a conventional process, a detailed description thereof will be omitted.

Radio module 18 is connected to the CPU 14. Although not shown in detail, the radio module 18 receives a high frequency signal transmitted from a radio base station through an antenna and filters only a required band; A receiver which amplifies the weak high frequency signal filtered by the reception filter to an arbitrary level, mixes it with a local oscillation frequency, detects an intermediate frequency signal at the mixed frequency, and demodulates the original signal into a original signal; and a signal demodulated from the receiver Radio signal processing unit for signal processing, a frequency synthesizer for generating a frequency corresponding to the transmission and reception frequency through the radio signal processing unit, and an interface unit provided for interfacing the radio signal information to the CPU.

In addition, there is provided a network adapter 20 interconnected via a bus, a USB (Universal Serial Bus) port that can connect a variety of multimedia including a computer, and a public telephone network using a public telephone PSTN (Public Switching Telephone) It includes a general telephone connection communication port for connecting to a network, and an internet connection communication port for connecting to the Internet. At this time, the Internet connection communication port is preferably a URL processing unit for performing a Uniform Resource Locator (URL) call of any website, and the URL storage unit is accessed from the URL processing unit and the URL storage unit for storing the URL is further connected.

On the other hand, a CD drive 22 is connected to the bus, and a CD (not shown) is mounted to read sound data at the same time as rotation and light irradiation. In this CD drive 22, audio data is a standard playback speed of the CD. Is read from the CD. Of course, the CD drive 22 can also read audio data of a CD at a high speed of 16 times or 32 times the standard speed. The CD drive 22 is not limited to the above example, but an appropriate disk-type recording medium (for example, magneto-optical disc or DVD) can be used, and a drive suitable for a memory card can be used. The data read out by the CD drive 22 is not limited to audio data, but images, texts, program data, and the like can also be read.

Then, the MMC memory 24 capable of storing a large amount of digital audio data is connected to the bus and stores the audio data read out by the CD drive 22. As preprocessing for writing audio data into the MMC memory 24, audio data read out by the CD drive 22 is processed via the compression encoder 26 and the RAM 10.

The compression encoder 26 executes the compression incubation process by any compression method so that the compressed audio data produced by compression encoding may be written and stored in the MMC memory 24 through the RAM 10 or externally through the decoder. You can also output Usually, the input sound data is supplied to the compression encoder 26 via an A / D converter (not shown). Then, compression encoding is performed as described above.

On the other hand, when the compressed audio data is stored in the MMC memory 24 as described above, the compressed audio data is read in order to read it from the MMC memory 24, and the read data is a compressed decoder for decoding the bus ( 28). Thereafter, the decoded data is output to the outside through a D / A converter (not shown), an amplifier (not shown), a speaker (not shown), and a connection terminal (not shown). Of course, it is well known that the compression decoder 28 has an algorithm corresponding to the algorithm for performing the encoding.

Here, although the compression encoder 26 and the compression decoder 28 have been described in connection with the MMC memory 24 as an embodiment, it is well known that the function can be performed by software processing of the CPU 14. . In addition, the compression encoder 26 may be connected to the microphone 30 so that the user's voice can be externally input and stored, and the compression decoder 28 is connected to an external output device such as a speaker (not shown). Can be.

2 is a diagram schematically showing the configuration of each execution mode configured in the first mode and the second mode according to an embodiment of the present invention. As shown in FIG. 2, for example, a first mode consisting of a CD1 mode, a relaxation mode, and a hot mode and a second mode consisting of the CD2 mode, the MP3 mode, the relaxation mode, the hot mode, and the radio mode are configured to each first. The mode execution and the execution mode of the second mode are distinguished to control each of them. That is, when the first mode is executed, the second mode is stopped. If the first mode is executed while executing the second mode, the second mode is temporarily stopped. The temporary pause mode continuously reproduces the playback section in the execution mode. In the present invention, the first mode and the second mode are not limited to both a specific manual operation mode and programming, and these functions can be selectively used.

The operation control process of the digital audio station of the present invention configured as described above will be described.

3 is an overall flowchart of execution modes for execution in a digital audio station according to an embodiment of the present invention. As shown in FIG. 3, when power is supplied to the digital audio station (S10), the entire system is initialized (S12). When initialization is performed, it is searched whether there is an execution program preset by the user (S14). If there is no execution program preset by the user, the execution standby state is maintained to prepare for execution according to the execution signal of a specific mode. In addition, the sound reproducing apparatus is reproduced according to a user's operation (S16). This has a general algorithm that can reproduce the normal sound reproduction apparatus separately. That is, the function of selecting, reproducing, stopping, repeating, etc. of the sound reproducing apparatus is performed.

On the other hand, if there is an execution program set in advance by the user, it is next calculated by calculating the date on which the execution program is input (S18). That is, it is determined whether an arbitrary setting time has elapsed after the execution program is input. If the input setting time has elapsed, the user inputs the program again (S20), and if the input setting time has not elapsed, a control signal for reproducing the corresponding execution mode at the corresponding time is output in the set execution program order (S20). S22). Accordingly, one of the modes, that is, the execution mode of the CD player, the MP3 player, or the radio, is executed. At this time, the audio data of the mode to be executed is digitized by arbitrary time units and temporarily stored in the RAM 10 (S24). Of course, it will only save for the last time it was played. This is to maintain the execution continuity of the mode that was running.

On the other hand, it is determined whether the execution signal of the specific mode which is another mode is input by the user during the execution of any one mode (S26). As a result of the determination, when there is a request for execution of another specific mode, the other specific mode is executed. However, in the present invention, switching to another specific mode is not performed immediately. This will be described in detail with respect to the reason and the control process in FIG. If there is no execution request in another specific mode as a result of the determination, it is next determined whether there is a relaxation key input (S28) or hot key input (S30), and if there is no input of the relaxation key and hot key, the execution program is executed. If it is completed (S32), the process proceeds to step S22, and when the execution program is completed, the execution program or the system is terminated.

4 is a flowchart illustrating a system initialization process. As shown in FIG. 4, header information of a disc inserted into each sound reproducing apparatus is loaded (S121). Thereafter, the database is searched and compared with the header information previously stored (S122). When the comparison search result (S123) and the header information is matched, the process proceeds to the step S14 of FIG. 3, and if there is no matching header information, the header information loaded in the system initialization process is stored and updated in the database (S124). ).

5 is a flowchart when a specific mode execution key is input. This is the best command that precedes the execution command of the data already programmed, and corresponds to the case where the mode change occurs with the user's key input as the highest priority. When an execution key of a specific mode is input by the user, as shown in FIG. 5, the silent region is identified by searching and determining the digital audio data stored in the temporary memory in an arbitrary mode being executed (S261). When the silent region is identified, the execution is performed from the arbitrary mode being executed to the silent region. At the same time, the execution stop section is stored in the temporary memory (S262). Thereafter, the progress to another specific mode is made as a ratio (S263). On the other hand, it is determined whether execution of the other specific mode is completed (S264), and when execution of the specific mode is completed or stopped by the program or by the user, the execution stop section stored in the temporary memory is searched. When the search is completed, the continuous execution is continued from the execution stop section previously executed in order by the program (S265).

Fig. 6 is a flowchart when a relaxation key is input. As shown in FIG. 6, when a relaxation key is input, the setting value of the execution time and execution mode is loaded into the memory from the program corresponding to the relaxation key and executed (S281). When the loaded setting value is provided to the user through a display and the like, and the user wants to change the setting value (S282), the relaxation program is changed and stored by performing key input or the like (S283).

On the other hand, if the set value is not changed, it is next determined whether or not the disc insertion section of an arbitrary sound reproducing apparatus is opened (S284). In other words, if the sound reproducing apparatus is closed after the opening, a medium for storing audio data, that is, a disc may be replaced. If it is determined that it is closed after opening, it is compared with the header information recorded in the existing database to determine whether it matches (S285). At this time, if it is different from the existing header information, the new header information is stored in the database to update the database (S286), and the header information is read (S287).

In addition, it is determined by the user whether the relaxation program has set a specific execution list in a specific mode (S288). In other words, it is determined whether the user is programmed to reproduce only the execution data desired by the user in any particular mode. If there is no specific execution list, a list is created in the corresponding execution mode and executed in order (S289). If there is a specific execution list, a list having a specific execution order is created and executed in list order (S290).

On the other hand, in step S284 and step S285, if the disc insertion unit of the sound recording / playback apparatus is not opened or if the existing database header information matches even if it is opened, the disc is not replaced and the flow proceeds to step S288.

7 is a flowchart when a hotkey is input. As shown in FIG. 7, when a hot key is input, a setting value for an execution time and an extension of an execution mode is loaded into a memory and executed from a program corresponding to the hot key (S301). Here, the difference from the program related to the relaxation mode of FIG. 6 is that, for example, the relaxation program determines whether data is actually executed and executes it according to the program order, but the program related to this hot mode is actually executed. By identifying the extension of the data, it is determined whether the extension is present and executed according to the program order.

When the loaded setting value is provided to the user through a display or the like and the user wants to change the setting value (S302), the user can perform a key input or the like to change the hot program and store it (S303).

On the other hand, if the set value is not changed, it is next determined whether or not the disc insertion section of an arbitrary sound reproducing apparatus is opened (S304). In other words, if the sound reproducing apparatus is closed after the opening, a medium for storing audio data, that is, a disc may be replaced. If it is determined that it is closed after opening, it is compared with the header information recorded in the existing database to determine whether it matches (S305). At this time, if it is different from the existing header information, it is then determined whether the newly replaced disk has the same extension (S306). If the same extension does not exist, the operation of the execution mode and the execution mode for executing the newly inserted disc are stopped during the execution time (S307). On the other hand, if they have the same extension, the data of the same extension is created in a list to update the database (S308), and the header information is read out (S309).

In addition, it is determined by the user whether the hot program has set a specific execution list in a specific mode (S310). In other words, it is determined whether the user is programmed to reproduce only the execution data desired by the user in any particular mode. If there is no specific execution list, a list is created in the corresponding execution mode and executed in sequence (S311). If there is a specific execution list, a list having a specific execution order is created and executed in list order (S312).

On the other hand, in step S304 and step S305, if the disc insertion unit of the sound reproduction apparatus is not opened or if the existing database header information is identical even if it is opened, the disc is not replaced and the flow proceeds to step S310.

8 is a flowchart illustrating a process of processing header information according to execution mode switching. As shown in Fig. 8, the switching of the execution mode may be switched by the user's programming or by the user's programming for the relaxation mode and the hot mode, in which case the specific execution mode and lease according to any program. It is determined whether the execution mode to be executed next is the same as the previous execution mode during the regeneration by step (S221) (S222). As a result of the determination, if the execution modes are not the same, execution mode header information to be executed next before the previous execution mode ends is loaded into the cache memory (S223). As a result, the CPU can directly access the header information in the cache memory, thereby reproducing the next execution mode without time delay. Thereafter, it is determined whether the execution mode previously executed is terminated (S224), and data of the corresponding address is read from the cache memory to output the data (S225). On the other hand, if the execution mode is the same in step S222 and step S224, or if the previous execution mode is not finished, the process proceeds to step S221.

9 is a flowchart illustrating a process of searching for and determining a silent region. As shown in FIG. 9, first, digital audio data stored in a temporary memory is transmitted to a CPU through a bus (S2611). Thereafter, the transmitted digital audio data is searched for the silent region by comparing with the preset reference data (S2612). If it is determined that there is no silent region as a result of the search, a region in which no sound is generated is determined based on the level setting value of the sound or noise for a predetermined time (S2613). If an area below the set value is found, the CPU executes the sound reproduction until the silent region, and then outputs a control signal for driving the next sound reproduction apparatus (S2614). As a result, the operation of the sound reproducing apparatus is stopped, and execution of another mode is performed.

Meanwhile, in operation S2613, all digital audio data stored for a predetermined time is output to the temporary memory (S2615).

As described above, the control method of the digital audio station according to the present invention can provide convenience for the user since the frequent program re-input process due to the replacement of the disk, which is a medium for storing audio data, is eliminated. In addition, since the natural continuity of the sound output can be maintained, not only to provide comfort to the user, but also accurate continuous reproduction can be realized by reproducing the continuity of the sound output through address grasping in a storage means such as an MMC memory. In addition, it is possible to provide convenience to the user since it is not necessary to perform repeated key input for the previously executed mode.

The present invention is not limited to the above-described embodiment, and it will be apparent that many modifications are possible by those skilled in the art within the technical spirit of the present invention.
