That is, on the play list screen 500 shown in FIG. 5, a list of a plurality of sound files recorded on the HDD 251 is displayed. Similarly, when the " CD Playlist " menu is selected among the submenus shown in FIG. 4, a playlist screen (not shown) providing a list of sound files recorded on the CD is displayed.

Referring to FIG. 5, sound files related to the execution of the "juke box" are recorded as two subfolders ('Classic' and 'Beatles') and a plurality of 'mp3' files in the 'Root' folder of the HDD 251. It can be seen that. Among the sound files to be reproduced, the highlight bar (Highlight-bar) is moved to the sound file to be reproduced using the direction keys 313, 315, 317, and 319 of the remote controller 300, and then the enter key 321 is moved. It can select by operating. The selected sound file is indicated by a '√' mark next to the sound file.

Here, when a play command for the selected sound file is applied, the GUI screen as shown in FIG. 6 is listed up on the television 100, and the selected sound file is reproduced in a predetermined order. FIG. 6 is a diagram illustrating a play list screen in which a selected sound file list is displayed among sound file lists recorded on the HDD of FIG. 5.

Referring to FIG. 6, the play list screen 600 is roughly divided into an upper region (up), a middle region (mid), and a lower region (lower). In the upper area up of the play list screen 600, a "juke box" or a "play list" is displayed, and in the middle area mid, a list of sound files selected in the screen of FIG. 5 is displayed and a lower area (lower). ) Displays key operation usage information of the remote controller 300 corresponding to the use of the play list screen 600.

In addition, a "display menu" (indicated as "Slide Show" in the drawing) for implementing a slide show is provided in the predetermined first region 610 of the middle region mid and currently in the predetermined second region 620. There is provided a screen (not shown) displaying schematic information (eg, singer, composer, lyrics, announcement year, etc.) on the sound file being played. A slide show is a function in which a plurality of still images are alternately displayed at regular intervals while a sound file such as music is playing.

While the tuned sound file is reproduced in a predetermined order, the play list screen 600 as shown in FIG. 6 is displayed on the television 100. At this time, when the remote controller 300 is operated to select the "display menu" displayed in the first area 610 to implement the slide show, the television 100 displays the periodic setting menu screen as shown in FIG. 700 is displayed.

The period setting menu screen 700 may set the display period of the still image that is alternately displayed in the predetermined second area 620. On the screen as shown in FIG. 7, the display period (unit: second) may be set by manipulating an icon indicated by '◀' or '▶'. For example, if the icon marked '◀' is selected, the display period is shortened. If the icon marked '▶' is selected, the display period is extended.

If the 'SELECT' button is selected by operating the remote controller 300, the display cycle is finally set, and the slide show function is executed. That is, the slide show is executed in the predetermined second area 610 of FIG. 6 so that a plurality of still images are alternately displayed for the set display period.

At this time, the files for the plurality of still images used in the slide show are recorded in the same folder as the sound file selected for playback or the sound file currently being played. For example, when there are five still image files recorded in the same folder as the files of the play list screen 600 of FIG. 6, when the slide show is performed, five still image files are sequentially displayed for the set display period. Repeat this.

As a result, the sound files displayed on the play list screen 600 are reproduced in a predetermined order, and together with the still images, the slide shows are executed in the predetermined order.

The decoding of the still image file for the execution of the slide show will be described later in detail with reference to FIG. 9.

Meanwhile, when the predetermined second area 620 is selected by operating the remote controller 300 on the screen as shown in FIG. 6 while the slide show is being executed, the predetermined still image being executed is full screened as shown in FIG. 8. That is, the predetermined still image is enlarged to correspond to the size of the television 100, and is displayed to be superimposed on the play list screen 600. It is preferable that the slide show proceed even after the full screen is executed. In addition, when the full screen is to be released, it can be released by operating the remote controller 300.

9 is a flowchart illustrating a slide show control method according to FIG. 3.

3 to 9, first, a play list screen 500 as shown in FIG. 5 is displayed in order to select and play a sound file recorded on the HDD 251.

3 to 9, first, by operating the menu key 311 and the direction keys 313, 315, 317, and 319 of the remote controller 300 on the television 100, a menu guide list screen as shown in FIG. 4 ( 400 and the play list screen 500 as shown in FIG. 5 are sequentially displayed.

Then, after the sound file to be reproduced is selected by the operation of the remote controller 300 on the play list screen 500 as illustrated in FIG. 5, when a play command signal is received (S905), the main controller 260 may display a television. The playlist screen 600 as shown in FIG. 6 is listed at 100.

In addition, when step S905 is performed, the main controller 260 reads the selected sound file and then controls the MPEG decoder 263 to sequentially decode the selected sound file (S910).

The main controller 260 temporarily stores the decoded sound file in the second SDRAM 267 (S915). In general, 'mp3' sound files are temporarily decoded at 128kbps (Kbit per sec) bitrate. For example, when a music file is played for about 4 minutes, the storage capacity required for storing the decoded file is as follows.

128 Kbit / sec * 4 minutes * 60 seconds = 30720 Kbit, and 1 byte is 8 bits,

30720 Kbit / 8 bit = 3840 KByte (= 3.84 MByte).

That is, when a general 'mp3' file is decoded and temporarily stored in the second SDRAM 267, a reproduction amount of about one minute is stored in approximately 1 MByte. Accordingly, when the second SDRAM 267 has a storage capacity of 64 MBytes, it can be seen that about 16 songs can be temporarily stored in the second SDRAM 267 at the same time.

The predetermined sound file stored temporarily is converted into an analog signal by the audio D / A converter 235 and then reproduced through a predetermined output terminal and a speaker (not shown) (S920).

For example, as shown in FIG. 6, when a play command for three sound files is received, step S910 decodes 'Say Goodnight', 'If', and 'The Whistler's Song' sequentially, and in order of decoding, each sound file. Is temporarily stored in the second SDRAM 267. In addition, when 'If' is decoded, the temporarily stored 'Say Goodnight' is reproduced by D / A conversion.

When the temporarily stored sound file is reproduced as in step S920, when the "display menu" shown in the first predetermined area 610 of FIG. 6 is selected through the remote controller 300 (S925), the main controller 260 Check whether or not a plurality of still image files are recorded in the folder in which the selected sound files ('Say Goodnight', 'If', 'The Whistler's Song') are recorded (S930).

If it is determined in step S930 that a plurality of still image files are recorded in the same folder as the folder in which the sound file is recorded, the main controller 260 causes the period setting menu screen 700 as shown in FIG. 7 to be displayed. When the display cycle of the still image is set by the operation of the remote controller 300 (S935), the main controller 260 controls the MPEG decoder 263 to sequentially decode a plurality of still image files recorded in the same folder. After that, it is temporarily stored in the second SDRAM 267 (S940).

In operation S940, preferably, if the display period is not set by the operation of the remote controller 300, the main controller 260 controls to proceed with the slide show in the display period preset to the default value.

In operation S940, the main controller 260 allows the still image file to be decoded when the audio decoder is not decoded and the MPEG decoder 263 is in an idle state. That is, while the temporarily stored sound file is played, the still image file is decoded and temporarily stored.

At this time, if there is no storage space for temporarily storing the predetermined still image file decoded in step S940, the main controller 260 is a predetermined still image file decoded when the temporarily stored sound file is reproduced and the storage space is regenerated To be temporarily stored.

Then, the temporarily stored still picture file is encoded by the video encoder 237 and then reproduced on the television 100 (S945). That is, the plurality of still image files recorded in the same folder as the selected and reproduced sound files are sequentially decoded and temporarily stored, and then alternately displayed on the screen for the display period set in step S935 to execute the slide show.

In addition, in order to alternately display a plurality of still image files on the screen by a set display period, the main controller 260 controls the MPEG decoder 263 to repeat the process of sequentially decoding the plurality of still image files.

If the predetermined second area 620 of the play list screen 600 is selected by the operation of the remote controller 300 while the slide show is being executed as in step S945 (S950), the main controller 260 is executing. The predetermined still image is enlarged and made full screen (S955). That is, the predetermined still image is enlarged to correspond to the size of the television 100 by the control of the main controller 260, and is superimposed on the play list screen 600. It is preferable that the slide show proceed even after the full screen mode is executed. In addition, when the full screen is to be released, it can be released by operating the remote controller 300.

On the other hand, during the execution of the step S930 or S955, when the playback of the selected sound file is finished (S960), the main control unit 260 also ends the slide show (S965). In addition, if the reproduction of the selected sound file is terminated during the operation of step S930 or S955 (S960), the main controller 260 may of course keep the slide show running.

Meanwhile, the plurality of still images capable of implementing the slide show in step S930 are not only recorded in the same folder as the currently selected sound file, but also a plurality of still image files recorded on the recording medium may be selected to implement the slide show. It may be.

As described above, if the slide show function is selected while the audio file is being played, the separate decoder is sequentially and repeatedly decoded and output when the MPEG decoder 263 is in an idle state, thereby adding a separate device. It is possible to deliver more effective information visually and visually to the user.

While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.

According to the recording / playback apparatus having the slide show function and the control method thereof according to the present invention, the audio file and the still image file can be decoded in a predetermined order by using one decoder provided. Accordingly, when a decoded sound file is being played, when a slide show implementation for a plurality of still image files is requested, it is possible to simultaneously perform music playback and a slide show by decoding the still image files when the decoder is idle. It is possible.
