4 is a flowchart illustrating a method for automatically reproducing a file according to an exemplary embodiment of FIG. 2, in which a file for automatic replay recorded in the DCD 10 when the DCD 10 is newly inserted into the engine unit 120 is automatically displayed. It is a flowchart showing the method of reproduction.

When a new DCD 10 is inserted into the engine unit 120 by the user (S401), the DCD deck unit 122 has a file corresponding to a file for automatic reproduction among the files recorded in the inserted DCD 10. Search for Here, the method for searching whether a file for automatic playback exists in the DCD 10 may include an extension of each of the files recorded in the DCD 10 and an extension preset and stored in the memory 143. The comparison is made (S403). That is, if a file having the same extension as the preset extension is present in the memory 143 among the files recorded in the DCD 10 (S405), the DCD deck unit 122 may have the same extension as the preset extension in the memory 143. A file having an extension is recognized as a file for automatic reproduction (S407). When the DCD deck unit 122 recognizes that the file for automatic reproduction exists in the DCD 10, the DCD deck unit 122 transmits a signal indicating that the file for automatic reproduction exists in the engine microcomputer 128. The engine microcomputer 128 transmits a signal received from the DCD deck 122 to the DSP 141 of the host 140 through the engine interface 129.

When the DSP 141 receives a signal indicating that a file for automatic reproduction exists in the DCD 10 from the engine microcomputer 128, the DSP 141 sets the portable device to the automatic reproduction mode (S409). The auto play mode refers to a mode in which the portable device is controlled by the DSP 141 so that the auto play file is automatically reproduced in association with the insertion of the DCD 10 into the engine unit 120. That is, the DSP 141 causes the LCD display 145 to display the image information when the file for automatic reproduction is made up of image information. Alternatively, when the file for automatic reproduction is composed of sound signals, the DSP 141 outputs the sound signals to the audio output unit 146. In addition, when the file for automatic reproduction is composed of sound signals and image information, it may be implemented to be simultaneously reproduced on the LCD display 145 and the audio output unit 146 (S411). Here, the DSP 141 is for a predetermined time so as not to be interrupted by other signals received for a predetermined time during which the image information and / or sound signal output through the LCD display 145 and / or the audio output unit 146 is output. It is preferable that the next key input signal input by the user is implemented not to respond (S413). In this case, the DSP 141 determines whether a predetermined time has elapsed after the start of outputting the image information and / or sound signal (S415), and when a predetermined time has elapsed, subsequent key input signals input by the user thereafter. In accordance with the present invention, the corresponding file may be implemented to be played (S417). Here, the predetermined time at which the image information and / or sound signal is output is set and recorded together when the image information and / or sound signal is recorded in the DCD 10, and is preferably implemented so as not to be changed by the user. . However, in this case, the user's forced viewing requires a predetermined time for outputting the image information and / or the audio signal to a minimum time.

The DCD deck unit 122 compares the extension of each of the files recorded in the DCD 10 with the preset extension stored in the memory 143 (S403) and determines that there is no file having the same extension as the preset extension. The lower surface (S405), the DCD deck unit 122 transmits a signal to the DSP 141 that the file for automatic reproduction does not exist in the DCD (10). When the DSP 141 receives a signal from the DCD deck unit 122 that a file for automatic reproduction does not exist in the DCD 10, the DSP 141 sets the portable device to the standby reproduction mode (S419). The standby play mode refers to a mode in which the portable device controls the DSP 141 to fetch a file corresponding to the key input signal from among the files recorded in the DCD 10 according to a subsequent key input signal of the user and to process the portable device. Accordingly, the DSP 141 controls the portable device to reproduce the corresponding file according to the subsequent key input signal by the user in the set standby playback mode (S417). Thus, the method of automatically reproducing the file for automatic reproduction recorded in the DCD 10 when the DCD 10 is newly inserted into the engine unit 120 is terminated.

FIG. 5 is a flowchart illustrating a file automatic playback method according to another embodiment of FIG. 2, in which a file for automatic playback recorded in the DCD 10 mounted when power is supplied to the engine unit 120 is automatically played. The method is shown.

When power is applied to the engine unit 120 (S501), the DCD deck unit 122 determines whether the DCD 10 is mounted on the engine unit 120 (S503). If the DCD 10 is mounted on the engine unit 120, the DCD deck unit 122 compares the extensions of the files recorded in the DCD 10 with the extensions previously set in the memory 143 (S505). ). Subsequently, the control process of the portable device according to the search for the file for automatic playback is the same as that of FIG.

When power is applied to the engine unit 120 (S501), when the DCD deck unit 122 determines that the DCD 10 is not mounted on the engine unit 120 (S503), the DSP 141 determines the DCD deck. The unit 122 receives a signal indicating that the DCD 10 is not mounted on the engine unit 120 and terminates the file automatic reproduction method of the portable device according to the signal. The DCD deck unit 122 waits for the DCD 10 to be inserted into the engine unit 120. At this time, when the DCD 10 is inserted into the engine unit 120, the DSP 141 performs the file automatic reproduction method of the portable device according to the method shown in FIG.

Thus, the file for automatic reproduction recorded in the DCD 10 is automatically supplied for a predetermined time according to the power supply to the engine unit 120 or the insertion of the file for automatic reproduction into the engine unit 120 of the DCD 10 in which the file for automatic reproduction is recorded. In addition to being played back, the contents of the file for autoplay can be clearly transmitted to the user by not interrupting the play of the file for autoplay for a predetermined time.

According to the present invention, a portable device for automatically reproducing a designated file can automatically play a file for automatic reproduction recorded on a recording medium in conjunction with power supply to the portable device or insertion of a recording medium into the portable device. .
