4A and 4B are diagrams schematically showing a video reproduction setting screen according to an embodiment of the present invention, and FIGS. 5A to 5D are diagrams schematically showing a video list display screen according to an embodiment of the present invention.

Referring to Figures 1 to 5d as a whole the video list display method according to the present invention will be described as follows. First, the preview video reproduction setting process of step S11 is performed in the mobile communication terminal 100 in the standby state (S10).

The preview video playback setting process according to the present embodiment is started through a process S111 in which the user requests the preview video playback setting through the key input unit 160.

When the preview video playback setting is requested, the list generator 194 of the controller 190 performs a process S112 of displaying a list of all videos currently stored in the storage unit 170 as shown in FIG. 4A.

Next, in step S113, the user selects one video (eg, a “stone feast image”) that the user wants to set by using the cursor C, and then inputs a confirmation key 164. In operation S114, the playback setting unit 192 of the controller 190 displays a preview video playback setting screen for obtaining preview playback setting information (hereinafter, referred to as playback setting information).

The reproduction setting information according to the present embodiment includes reproduction start time data, reproduction speed data, and enlargement / reduction ratio data. Therefore, the preview video reproduction setting screen according to the present embodiment, as shown in Fig. 4b, the playback start time data input field (T), the playback speed data input field (V), and the zoom ratio data input field (Z). ).

The playback start time indicates when the preview video is played for the first time. Therefore, the user inputs a time point at which the preview playback starts (for example, 00:14:33) of the entire playback time of the selected video in the input field T. On the other hand, when the user inputs a time point (eg, 00:16:33) exceeding the total playing time (eg, 15 minutes and 55 seconds) of the selected video, playback is not possible at that time. Therefore, in this case, the playback setting unit 192 preferably checks this and displays the fact that playback is impossible through a pop-up window or the like.

The playback speed sets the playback speed of the video when the preview video is played. Therefore, the user inputs the preview playback speed of the selected video in the input field (V). In the case of Fig. 4B, the 1x speed (e.g., 1x), which is the original reproduction speed, is set. However, if you want to reproduce at a higher speed, various settings such as 2x speed (eg 2x) and 4x speed (eg 4x) are possible.

The enlargement / reduction ratio is set to enlarge or reduce the video when the preview video is played. Therefore, the user inputs an enlargement or reduction ratio of the selected video in the input field Z based on 100%. When the user enters 50%, the video is displayed by 50% smaller than the size (P of FIG. 5B) displayed by default. Similarly, if the user inputs 200%, the video is displayed 200% larger than the size displayed by default.

However, since the preview video according to the present embodiment is displayed together with the list as shown in FIG. 5B, the preview video cannot be displayed more than a predetermined size. Therefore, in the present embodiment, when the user sets the preview video to be enlarged (for example, 200%) and is displayed, a method of expanding and displaying only a specific part of the video as shown in FIG. 5D is used.

If the user inputs all the reproduction setting information through the preview video reproduction setting screen of FIG. 4B in operation S115, the reproduction setting unit 192 stores the input reproduction setting information in the reproduction information DB 172 in operation S116.

6 is a diagram schematically showing the structure of a reproduction information database according to an embodiment of the present invention. Referring to this, the reproduction information DB 172 includes a video name, a reproduction start time, a reproduction speed, and an enlargement / reduction ratio field.

The video name field is a field for inputting a name of a video to which the reproduction setting information is to be applied. The video name field is input together with the path and file name of the video.

Data input through the above-described preview moving picture reproduction setting screen are respectively stored in the reproduction start time field, the reproduction speed field, and the zoom ratio field.

Meanwhile, the present embodiment uses a method of storing playback setting information set by the user through the playback information DB 172 which is separate from each video file. However, the present invention is not limited thereto, and various applications are possible, such as adding playback setting information for each video to the corresponding video file and storing the video.

Subsequently, in step S117, the playback setting unit 192 checks whether there is a preview playback setting request for another video. Accordingly, when a play setting request for another video is input from the user, the list generator 194 enters the process S112 and displays the video list again as shown in FIG. 4A to the user. The playback setting unit 192 repeatedly performs steps S112 to S116 according to a user input.

When the preview video playback setting process is completed through the above process, the playback information DB 172 stores the playback setting information for all the videos set by the user.

Next, in step S12, the user requests a list of videos in order to search (or play) the video. Accordingly, the list generator 194 searches for all video files stored in the storage unit 170 and displays a video list as shown in FIG. 5A. In this process, the list generator 194 displays each item using a file name or a title name of the corresponding video.

When the video list is displayed as shown in FIG. 5A, the user moves the cursor C through the direction key 162. When the user repeatedly inputs the direction key 162, the video processor 196 determines that the user inputs the cursor C. Accordingly, the video processor 196 moves and displays only the cursor C while the list is displayed as shown in FIG. 5A.

In this process, when the input of the direction key 162 of the user is stopped, the cursor C is located at one item. In this case, if there is no input of the direction key 162 for a predetermined time (eg, 1 second), the video processing unit 196 recognizes that the user has selected the corresponding item.

In operation S16, the video processing unit 196 extracts reproduction setting information corresponding to the selected item from the reproduction information DB 172.

In operation S17, the video processing unit 196 displays the video with the list based on the extracted playback setting information.

At this time, the video processing unit 196 displays a video of an item (for example, a stone feast image) at which the cursor C is located, directly below the selected item as shown in FIG. 5B. Therefore, items that were located below the selected item (eg, English lecture 1, meeting contents recording, English lecture 2, etc.) are pushed down to the lower portion of the video and displayed.

In this process, the video processing unit 196 displays the corresponding preview video according to the playback setting information set in the playback information DB 172. For example, in the case where the playback information DB 172 is set as shown in FIG. 6, when the 'stone feast image' is selected, the video processing unit 196 may perform the 'stone feast image' at the playback position corresponding to 14 minutes and 33 seconds. Play the corresponding video. In addition, the video processing unit 196 reproduces the 'stone feast image' at 1x speed, that is, the basic speed, and reproduces the original size without enlargement or reduction. However, when the enlargement / reduction ratio is set to 100% (e.g. 200%) as described above, the video processing unit 196 enlarges a part of the video and plays the preview video as shown in FIG. 5D.

While the S17 process of playing the video on the selected item is performed, when the user inputs the direction key 162 again, the cursor C moves in the corresponding direction.

Accordingly, the video processing unit 196 removes a preview video of a previously selected item (eg, a “stone feast image”) from the screen. Accordingly, the video list is displayed again as shown in FIG. 5A.

In this case, when the user stops moving the cursor C again in operation S18, the video processing unit 196 determines that an item (for example, 'recording of meeting contents') at which the cursor C is located is newly selected by the user. do. In operation S18, the video processor 196 repeatedly performs operations S16 to S17 on the selected item and displays the preview video as shown in FIG. 5C.

Meanwhile, when the confirmation key 164 is input by the user while one video is selected, that is, when a play request for the selected video is input (S19), the controller 190 removes the video list display screen and selects the selected video. S20 process of playing a video is performed. Here, the video playback in step S20 refers to general video playback, not preview.

The method and apparatus for displaying a video list according to the present invention performed through the above process may preview a desired video in a video list display state. Therefore, there is an advantage that it is easy to check what content the selected video is.

Meanwhile, the method and apparatus for displaying a video list of a mobile communication terminal according to the present invention are not limited to the exemplary embodiments, and various modifications may be made by those skilled in the art within the technical idea of the present invention. For example, in the present embodiment, a case where a video list in which items are listed up and down is used is described as an example. However, the present invention is not limited thereto, and various applications are possible, such as scrolling left and right and applying the displayed list.

In addition, in the present embodiment, the case where the preview reproduction setting information includes the reproduction start time, the reproduction speed, and the enlargement / reduction ratio has been described as an example. However, the present invention is not limited thereto, and may include various types of data such as data indicating the size of the preview image or data indicating whether the preview reproduction is automatically performed.
