Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file selecting method and a reproducing apparatus in a reproducing apparatus, and more specifically, when a plurality of different kinds of content media, for example, optical disks, exist, files existing in the optical disks are recorded. The present invention relates to a file selection method and a playback device in a playback device, which can reduce a processing time until effective use and playback of a memory for expanding a file by designating a desired file before accessing.

[0002]

2. Description of the Related Art In a conventional content medium such as an optical disk, for example, there are a plurality of types of reproducible files such as images and sounds. The user was asked to select the file after searching and extracting the types of playable files.

Specifically, as shown in FIG. 5, first, a file of type 1 is searched and extracted before selecting a file (step ST41), and then, a file of type 2 is searched and extracted. (Step ST42), then search and extract files of type 3 (step S42).
(T43) Next, the file of type 4 is searched and extracted (step ST44), and after searching for all the files of the rubbing interface, the user is allowed to select and the file of the selected type is played.

As another method, a method is known in which the type of file to be preferentially reproduced is set in advance as the initial setting of the reproducing apparatus and the file is searched and extracted according to the setting.

[0005]

However, when the user described in the prior art selects an arbitrary file, the time required for the file search and extraction is (image file search and extraction) in the above-described method. Time + audio file search and extraction time), and even if the user wants to play an audio file, for example, the user must wait including the time to search and extract the image file, and as a result, the desired file can be searched and extracted. There is a problem that it takes time.

In the method described above, for example, when an image file is prioritized, and when the user wants to reproduce the image file, the user only waits for the image file search and extraction time, but reproduces the audio file. In this case, there is a problem in that the user has to wait for (image file search and extraction time + sound file search and extraction time).

Therefore, there is a problem to be solved by a method and apparatus capable of quickly searching and extracting a desired file without making the user wait until the time for searching and extracting a file which the user does not want to reproduce. .

And a composite output section 38 for outputting a composite signal from the DVD-video decoder 30. Among them, the output signal of the DA converter 25 is input to the audio amplifier 39, the signal from the composite output section 38 is input to the TV display 40, and the display signal from the display microcomputer 23 is output to the main body display section 41. .

In such a configuration, the system controller 21 is provided with a calculation section for judging whether or not the type of file to be reproduced first should be decided by the user's selection, and a user interface section for inquiring of the file type to the user. And a file information acquisition unit for searching and extracting a reproduction file according to user input,
It decodes and executes a program that combines a playback unit that plays a filter.

A control unit 1 equipped with such a program
8 is to specify the types of optical discs that are a plurality of different types of content media, and to search for and extract a desired file. A method of selecting a file and a method of automatically selecting a data optical disc and then selecting a file type will be described below with reference to the flowcharts of FIGS. 3 and 4.

A method of selecting a plurality of different types of files by turning on a predetermined button on a data optical disc is as shown in FIG. 3, first, an action for the user to select the type of a reproduction file, for example, "1"
Then, a plurality of different types of files can be selected (step ST1).
1).

For example, when the "2" button is pressed, a type 1 file is searched and extracted (step ST12),
When the "3" button is pressed, the type 2 file is searched and extracted (step ST13), and when the "4" button is pressed, the type 3 file is searched and extracted (step S13).
When the button "5" is pressed in T14), the type 4 file is searched and extracted (step ST15), and the desired file is reproduced (step ST16).

As described above, for example, when a plurality of types of reproducible files such as images and sounds exist on a recording medium such as an optical disk, and the user selects an arbitrary file from among them, the reproducing apparatus is used. The processing time for searching and extracting a reproducible file increases as the number of recorded files increases. As shown in the above-described flowchart, the present invention reduces the time for searching and extracting unnecessary files by using an interface that allows the user to select the type of file to be played before performing the search / extract processing of the playable file. The reproduction of the file intended by the user can be started in the shortest time.

More specifically, assuming that an audio file and an image file exist now, in the conventional case, both files are expanded in the memory and then the user selects the files. It is necessary to secure a memory capacity that can expand the files of. However, according to the present invention, by selecting either file type before expanding both files, the file on the selected side of either one may be expanded in the memory.

This is because the memory capacity for expanding two types of files is necessary even if it is simply calculated, and the memory capacity for expanding one type of file is sufficient. However, half the memory capacity is required. That is why the memory can be effectively used. The fact that the memory capacity can be suppressed to a small amount also has the effect that the processing time up to the reproduction can be shortened.

Next, a method for automatically selecting the data optical disk and then selecting the file type will be described below with reference to the flowchart shown in FIG.

First, when an optical disk which is a content medium is loaded in the optical disk loading section, an operation for automatically determining the type of the optical disk is performed, and if the optical disk is a DVD, it is determined to be a DVD (steps ST21, S).
T22).

In step ST21, if the disc is not a DVD, it is next discriminated whether it is a CD-DA, and a CD-
If it is DA, it is determined to be CD-DA (step S
T23, ST24).

In step ST23, if it is not CD-DA, it is next judged whether or not it is VCD, and VCD is determined.
If so, it is determined to be a VCD (step ST2).
5, ST26).

Next, in step ST25, VCD
If not, then it is determined to be a data optical disc, and the user selects the type of file to be reproduced (step ST27).

Then, for example, if the operation button "1" is pressed, the file of type 1 is searched and extracted (step ST28), and if the button "2" is pressed, type 2 is selected.
File is searched and extracted (step ST2
9) If the "3" button is pressed, the type 3 file is searched and extracted (step ST30), and if the "4" button is pressed, the type 4 file is searched and extracted (step ST31). File is reproduced (step ST32).

[0033]

As described above, in the file selecting method and reproducing apparatus according to the present invention, before reproducing a plurality of different types of files, for example, a video file and an audio file, either By selecting a file and playing the selected file, it is possible to not only reduce the amount of memory to be expanded but also shorten the time to access the file. .
