The DCD servo 124 drives the DCD deck 122 under the control of the engine microcomputer 128. The DCD deck 122 reads data from the DCD under the control of the engine microcomputer 128. The buffer 125 is for temporarily storing data to be recorded and reproduced when data is recorded and reproduced with respect to the DCD 10, and may use a static random access memory (SRAM). The engine memory 126 is for storing code values and control data of various command words promised between the DCD 10, the engine unit 120, and the engine unit 120 and the host 140. memory: flash RAM) can be used. The engine microcomputer 128 controls the DCD deck 122, the DCD servo 124, and the buffer 125. The engine interface 129 provides an interface between the engine unit 120 and the host 140.

The host 140 includes a DSP 141, a power supply unit 142, a memory 143, an external interface 144, an LCD display 145, an audio output unit 146, a voice input unit 147, and a key input unit 148. And a battery remaining amount detection unit 149.

The DSP 141 is connected to the engine interface 129 and accesses the engine unit 120 to control not only the recording and reading data but also the function of reproducing the read data and the entire digital device 100 for the DCD. The DSP 141 also controls the entire DCD device 100 so that reproduction / recording of the file is processed in accordance with attribute information of the data read out in units of files. In particular, the DSP 141 controls the LCD display 145 to be displayed in the reverse order of the recording time from the directory in which the most recently recorded file is stored. Also, the DSP 141 controls the DCD deck unit 122 so that the directory is displayed on the LCD display 145 according to the recording time information of the files recorded in the DCD. Needless to say, for this operation, the DSP 141 should be implemented to control the DCD deck unit 122 to retrieve recording time information of files recorded in the DCD.

The memory 143 is controlled by the DSP 141 and receives and stores recording time information and directory information of a file recorded from the DCD. The external interface 144 used a USB interface as an interface between the DCD digital device 100 and the PC 200.

The LCD display 145 is controlled by the DSP 141 and displays the directory of the file recorded in the DCD in the reverse order of the recording time from the directory in which the most recently recorded file is stored. In addition, when at least one of the hidden, writeable, filename change, file path, and delete of the file recorded in the DCD is edited by the user, the LCD display 145 displays the edited attribute information. This allows the user to confirm the update of the attribute information.

The audio output unit 146 outputs the audio data reproduced from the DCD 10 and outputs various messages generated by the DSP 141 as described later. The voice input unit 147 processes the voice command input from the user and delivers the voice command to the DSP 141. Of course, the user may input a command for the DCD digital device 100 through the key input unit 148. Here, the key input unit 148 is used for inputting a user's selection command for at least one of the directories displayed on the LCD display 145. In this case, the key input unit 148 is preferably implemented to position the cursor on the directory displayed on the LCD display 145, and move the cursor located so that the user can select the desired directory.

The mode switching unit 150 switches between the directory display mode in which the LCD display 145 displays a directory and other modes. The file routine for the file recorded in the DCD is displayed through the LCD display 145 when the mode switching unit 150 is set to the directory display mode. Here, the mode switching unit 150 may be included in the key input unit 148 and implemented to be switchable by an input key. When power is applied from the power supply unit 142, the mode switching unit 150 automatically detects the applied power and displays the directory automatically.

The register section 127 is composed of a control register 127a, a status register 127b, a byte counter register 127c, and a data register 127d, and each register is used for communication with the host 140. The host 140 selects a register to be accessed from among the registers of the register unit 127 according to the values of the two bit bits (DPI_ADD0 and DPI_ADD1) for the DCD interface. The host 140 performs a write operation on the control register 127a, and the engine 120 performs a read operation.

The control register 127a has the function control and interface interrupt enable / disable values recorded by the host 140. The host 140 can read only the status register 127b, and the engine unit 120 can both read and write the status register 127b. The status register 127b holds status information and interrupt reason information. The host 140 and the engine unit 120 may perform both write and read operations with respect to the byte counter register 127c. However, the host 140 may write to the byte counter register 127c only when the BUSY bit of the status register 127b is clear, and the data DATA bit of the status register 127b is set. Only return valid information is read from the byte counter register 127c. The byte counter register 127c contains the byte count for the next command, data, or status mode transfer. The host 140 and the engine unit 120 can both read and write the data register 127d. However, the host 140 writes the data to the data register 127d to transmit data to the engine unit 120 during the command and data out phases. In addition, the host 140 reads the data register 127d to transmit data from the engine unit 120 during the status and data in phases.

A data-link layer defining a method used for the exchange, a command layer recording commands related to data for the DCD 10 to control data accessed by the engine unit 120, and There are four layers of connection states, including an application layer including file data / meta data mapping and a user interface. The connection state of the four layers existing between the host 140 and the engine unit 120 is such that file data / metadata recorded in the DCD driven by the engine unit 120 is smoothly transmitted to the host 140 to be processed. To help.

4 is a flowchart illustrating a method of displaying a directory of a file recently recorded using the DCD digital device of FIG. 2 and a method of reproducing a file corresponding to the displayed directory. Referring to the drawings, the pilot device for a portable device and the operation of the portable device will be described.

When the DCD is inserted into the engine unit 120, the DSP 141 of the host 140 searches for a mode set by the mode switching unit 150 (S401). If it is determined that the mode set by the mode switching unit 150 is the directory display mode (S403), the DSP 141 retrieves recording time information of the files recorded in the DCD (S405).

5 is a diagram illustrating an example of a routine of files recorded in the DCD, and FIG. 6 is a diagram illustrating recording time information and a recorded directory of the files of FIG. 5. 5 and 6, three files a1, a2, and a3 are stored in the directory A, and one directory C and one file b1 are stored in the directory B. FIG. In addition, two files c1 and c2 are stored in the directory C stored in the directory B. That is, not only files but also files and directories may be stored together in one directory.

As described above, when it is determined that the mode set by the mode switching unit 150 is the directory display mode, the DSP 141 records recording time information on the files recorded in the DCD, that is, in the case of FIG. 07 and a2 retrieve recording time information on which each file is recorded, such as 6.28 17:28. The DSP 141 also searches the directory in which each file is recorded. Here, the directory in which the files a1, a2, a3 are recorded is A, the directory in which the file b1 is recorded is B, and the directory in which the files c1, c2 is recorded is C.

The DSP 141 displays the LCD display 145 in the reverse order of the storage time from the directory in which the most recently recorded file is stored according to the recording time information for each of the retrieved files (S407). In the case of the directory and file shown in FIG. That is, the order of the most recently recorded file in the reverse order of the recording time information is a3, b1, a2, c2, c1, a1, and the directories corresponding to each file are A, A / B, A, A / B / It becomes C, A / B / C, A.

By the method described above, the pilot of the portable device is displayed. In addition, the method of reproducing the file corresponding to the directory displayed on the LCD display 145 will be described in detail. The DSP 141 determines whether there is a user selection command for the directory displayed on the LCD display 145 (S409). ). Here, the user's selection command is input through the key input unit 148, and the DSP 141 receives a signal input by the user.

When a user's selection signal for at least one of the directories displayed on the LCD display 145 is received, the DSP 141 controls the audio output unit 146 to reproduce a file corresponding to the selected directory (S411). Here, for example, in the case of FIG. 7, if a file corresponding to the selected directory is selected by the user, the corresponding file is c2. At this time, the fourth directory and the fifth directory are the same, but the files corresponding to the actual directories are different. As shown in FIG. 7, in order to prevent confusion of a user due to the sameness of the displayed directories, it is preferable to add and display the name of a file corresponding to the end of the displayed directory. For example, the pilots corresponding to the files a3, b1, a2, c2, c1, and a1 in FIG. 7 are A / a3, A / B / b1, A / a2, A / B / C / c2, and A / B. It is preferable to implement such that it is displayed as / C / c1, A / a1.

If there is no selection signal input through the key input unit 148 for a predetermined time after the directory is displayed on the LCD display 145 or if a user's selection command input process is skipped, the DSP 141 displays the LCD display 145. The audio output unit 146 is controlled to play the file corresponding to the directory in the order shown in S413. That is, in the case of FIG. 7, the files a3, b1, a2, c2, c1, a1 are reproduced in order according to the order of the directories displayed on the LCD display 145. FIG.

If it is determined that the mode switching unit 150 is not set to the directory display mode, the DSP 141 may play the audio output unit so that the corresponding file is played in accordance with the corresponding mode type, for example, the manual mode, the voice recognition mode, or the like. 146). Thus, the process of displaying the file routine of the portable device and the process of playing the file corresponding to the displayed directory are ended.

Thus, the file routine display device of the portable device displays the directory in the reverse order of the recording time according to the recording time information at which the file is recorded, so that the user can easily find the recently recorded file. In addition, the portable device can first access a file of high interest by the user by reproducing from a recently recorded file.

 According to the present invention, the directory is displayed in the reverse order of the recording time according to the recording time information at which the file is recorded, so that the user can not only easily search for the recently recorded file but also easily access the recently recorded information of interest. It becomes possible.
