Mobile terminals developed simply for voice calls have evolved into multimedia devices that selectively provide additional features such as wireless Internet access, video calls, TV reception, radio reception, and camera shooting. Terminals and systems that receive satellite broadcasting, satellite DMB, and terrestrial DMB signals to watch broadcasts have been introduced.

As such, mobile terminals, which have been evolving as multimedia devices, are basically equipped with a large amount of memory, and users can store various types of video or audio files (hereinafter referred to as media files) in memory and play them whenever necessary. You are watching or listening.

For example, a mobile terminal such as a camera phone can be used to shoot a video, but it can be said that the captured video is generally played back from the shooting start point. That is, since playback of the captured video starts at the shooting start point or when the playback is paused, there is no method of quickly finding and playing the desired point. If there is a way to jump to the video recorded and find the desired position quickly from the point it will be convenient to the user. This is not only applied to the photographed video file, but also commonly applied to all types of media files that can be stored.

Accordingly, an object of the present invention is to provide a high-speed movement to a desired position with respect to a media file to be played, but a file search player and a file of a mobile terminal for high-speed movement within a file through an intuitive recognition means such as numeric key buttons.

And a file reproducing unit for controlling file reproducing by moving to a position mapped to a numeric key button input during file reproducing.

According to the features of the present invention as described above, by dividing the media file selected by the user into a plurality of sections according to the user's selection and mapping the respective divided position information with a number, the terminal during later playback of the media file When the user inputs a numeric key button that can be intuitively recognized, the user can move to a location mapped to the high speed search.

 Furthermore, the mapping table generation unit of the mobile terminal according to another embodiment of the present invention;

Each time a specified key is input during file playback, the file playback position information of the key input point is mapped with a numeric key button which can be inputted and stored.

According to this feature, the user directly inputs the points available for the high-speed search while the media file is played and maps them with the numeric key buttons, so that the user can perform the high-speed search while moving the points set by the user later.

In addition, the file playback unit of the mobile terminal according to another embodiment of the present invention;

If the input of the numeric key button is maintained for a predetermined time during file playback, the file data of the division section mapped to the numeric key button is repeatedly played.

According to this feature, the mobile terminal user can repeatedly watch or listen to a media file to be repeatedly played with a simple key operation.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

First, FIG. 1 illustrates a partial block diagram of a mobile terminal according to an embodiment of the present invention, and more specifically, illustrates a partial block diagram of a mobile communication terminal capable of receiving and storing a broadcast stream. 2 is a block diagram illustrating another configuration of the controller 200 of FIG. 1.

Referring to FIG. 1, first, a mobile communication terminal according to an exemplary embodiment of the present invention includes a key operation unit 100 including a plurality of numeric key buttons as a mobile terminal capable of playing a media file. The key operation unit 100 may further include a designation key and a file division command key necessary for implementing the present invention in addition to a plurality of numeric key buttons. The "specified key" and the "file split command key" may be defined as a key for designating a point to be jumped at a high speed and a key for indicating a file split. Since the file division can be instructed using the numeric keys specified in a specific mode or a point to be jumped, the " specified key " and " file division command key " must be provided in the key operation unit 100. There will be no.

In addition to the key manipulation unit 100, the mobile communication terminal further includes a media file storage unit 300 for storing media files. In the following description, the term "media file" is defined as a generic term for a video file and an audio file. The file stored in the media file storage unit 300 may be input through an interface unit capable of transmitting and receiving data with a peripheral device, and may be a media file received through a (satellite) broadcast signal receiver.

Meanwhile, the mobile communication terminal according to an embodiment of the present invention divides a media file selected by a user into a plurality of sections according to a user's selection, and maps each of the divided location information to a number, thereby reproducing the media file. If the terminal user inputs a numeric key button that can be intuitively recognized further comprises a control unit 200 for controlling to play from the position mapped thereto. As illustrated in FIG. 1, the controller 200 may be implemented as a mapping table generator 210 and a file player 220 module.

The mapping table generating unit 210 divides the media file selected from the storage unit 300 into a plurality of sections according to a file division command input through the key manipulation unit 100 and inputs respective division position information. It also serves to store mappings. In more detail, the mapping table generating unit 210 reads the header information of the file selected by the user, divides the file into a size desired by the user, and sequentially numbers the timestamp value corresponding to the start point of each divided section. Mapping with buttons (1,2,3,4, ..) creates one mapping table. The generated table is stored and managed in the file storage unit 300 or a system memory (not shown), so that the table can be moved to a location mapped to a numeric key button input later. The jumping point may be dynamically changed by the mapping table generator 210 described above.

Additionally, as a modified embodiment of the present invention, the mapping table generator 210 may map and store file playback position information (timestamp) at the time of key input with a numeric key button which can be input and stored every time a designated key is input during file playback. have.

In another alternative embodiment, the mapping table generator 210 may map and store file playback position information (timestamp) at a key input time with a numeric key button which can be input and stored every time a designated key is inputted while storing a broadcast stream. There will be.

The file reproducing unit 220 constituting the control unit 200 together with the mapping table generating unit 210 moves to a position mapped to a numeric key button input during file reproducing and controls the system to perform file reproducing. Do this. That is, the file reproducing unit 220 controls the file storage unit 300 to reproduce the file from a position corresponding to the input numeric key button with reference to the mapping table.

The file reproducing unit 220 may control the system so that the file data of the divided section mapped to the numeric key button is repeatedly reproduced if the input of the numeric key button is maintained for a predetermined time during file reproduction. The number of repetitions at this time may be programmed to match the input numeric key button, or may be repeated with a value set by the user.

In addition to the mapping table generating unit 210 and the file reproducing unit 220, the control unit 200 may be implemented by further including a reproducing position display unit 230 as shown in FIG. 2. This is to visually inform the terminal user of the current playback position. That is, the playback position display unit 230 generates data for displaying the total number of divisions of the media file being played and the current playback position, and outputs the data to the display unit. You can visually check the playback position.

Hereinafter, a file search and play method in a mobile terminal having the above-described configuration will be described in detail with reference to the accompanying drawings.

First, FIG. 3 is a flowchart illustrating a file search play of a mobile terminal according to an embodiment of the present invention, and FIG. 4 is a flowchart illustrating a mapping table generation process in a mobile terminal according to an embodiment of the present invention. It is an example. For reference, in the following description, it is assumed that a plurality of media files are already stored in the file storage unit 300 (S1).

Under this assumption, the terminal user may issue a file division command after selecting a file so that a fast search is performed on the stored media file. That is, the terminal user selects one of the stored media files through the key manipulation unit 100 and then requests n division of the selected files. If there is an n-division request of such a media file (S2), the mapping table generator 210 reads the header information of the file selected by the user (S3) and divides the corresponding file by the number input by the user, and divides the divided file by n. The timestamp value corresponding to the start point of the section is sequentially mapped with the numeric key buttons (1, 2, 3, 4, ..) to generate this as a mapping table (S4).

When a number key is input during playback of a media file in which mapping table generation is completed in a state in which a mapping table is generated for one media file as described above, the file player 220 refers to the mapping table and corresponds to the input number. The system is controlled to jump to a position so that playback is performed (S5). In this case, if the jumped point is not the point to be searched, the terminal user can quickly move to the target point by re-inputting a numeric key button that can be coincident with or near the target point.

As described above, the present invention divides the media file into a plurality of sections, but maps the starting point of each divided section with the numeric keys, so that the user can recognize the jumping points of the media file through an intuitive means called the numeric keys. The file will be searchable.

In some cases, the method further includes the step of displaying the total number of divisions of the currently playing media file and the current playback position in response to a user command, thereby allowing the user to visually display the total number of divisions of the currently playing media file and the current playback position. You can also check.

The method may further include mapping the file playback position information at the time of the key input with the numeric key button which can be input when the designated key is input during the playback of the media file and storing it in the mapping table. This is a useful way to designate a point where the user himself remains as a search point so that playback can be performed from that point later. This will be described in more detail with reference to FIG. 4.

First, in a state in which a media file is stored (S11), the terminal user may select one of the media files to play (or listen to) S12. If the user inputs a section designation key to set a point to be used for a later search during the playback output of the selected media file (S13), the mapping table generating unit 210 displays the file playback position information (time) at the time of the key input. A mapping table is generated (S14) by mapping a stamp) with an inputable numeric key button.

If the mapping table for the search points input by the user is created through the above-described method before the media file is finished playing, the file may be quickly searched by the method described with reference to FIG. 3.

That is, according to the present invention, the user can directly designate the points available for the high-speed search during the playback of the media file and map them to the numeric key buttons, so that the high-speed search can be performed while moving the points set by the user himself.

In FIG. 4, although search points are designated during playback of the stored media file, search points may be designated for broadcast streams stored without any modification. That is, the mapping table generating unit 210 maps the file playback position information of the key input time point to an inputable numeric key button every time a designated key is input while storing the broadcast stream, and stores the data in the table. High speed search can be achieved by moving from one point to another.

Of course, the embodiment of the present invention may further include the step of repeatedly playing the file data of the divided section mapped to the numeric key button if the input of the numeric key button is maintained for a certain time during file reproduction.

As described above, the present invention divides a media file selected by a user into a plurality of sections according to a user's selection, and maps each of the divided location information to an input numeric key button. There is an advantage that the high-speed search in the file is made by inputting a numeric key button that can be intuitively recognized.

 In addition, the present invention inputs points that can be directly used for high-speed search during media file playback or broadcast stream storage, and maps them with the numeric key buttons, so that the user can quickly search for points to be searched by simple input of the numeric keys. There are advantages to it.

On the other hand, the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. . Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
