For example, a content having high user preference among a plurality of playable contents may be displayed on a screen for a longer time than an image of content having low preference when scrolling.

By displaying the image of the content having a high preference as described above on the screen for a longer time, it is possible to provide the optimized content information to the user, it can be easy to search and search for the desired content from the user side.

4 is a flowchart illustrating a content image display method according to an exemplary embodiment of the present invention, and descriptions of the same as those described with reference to FIGS. 1 to 3 will be omitted below.

Referring to FIG. 4, the content reproducing apparatus displays some of the content images corresponding to the plurality of reproducible contents on the screen (step S1).

Thereafter, when a scrolling motion in the first direction is input from the user (step S2), the content reproducing apparatus moves the content images displayed on the screen in the first direction (step S3).

In step S3, as described with reference to FIG. 2, as the content images are moved in the first direction, at least one of the content images displayed on the screen may disappear from the screen, and at least one new content image may be displayed on the screen. have.

In addition, while content images are moved and displayed in step S3, the time when each of the content images is displayed on the screen may be determined to be proportional to the preference for the corresponding content.

For example, when the content images displayed on the screen are moved in the first direction by the scrolling operation, the image of the content with low preference among the content images displayed on the screen disappears after being displayed on the screen for a short time and the content with high preference The display time may be set to disappear after the image is displayed on the screen for a long time.

According to an embodiment of the present invention, the content preference may be learned and determined according to a user's usage pattern, and more specifically, may be determined according to the user's viewing time or the number of selections of the corresponding content.

For example, whenever a user watches or selects a broadcast channel, the viewing time and the number of selections may be accumulated and stored for each channel, and as the stored viewing time and the number of selections increase, the preference for the channel increases.

Meanwhile, the preference of the content may be divided into n preset stages, and for example, the content may be determined to have a value of 1 to n.

In addition, when there are a plurality of users of the content reproducing apparatus according to an embodiment of the present invention, the preference for each of the plurality of contents for each user may be determined and stored in a memory (not shown). If confirmed, content preferences corresponding to the user may be read from the memory and used.

According to another embodiment of the present invention, preference values for the content may be used with preset preference values.

Meanwhile, as illustrated in FIG. 3, when the user touches the screen 10 to input a scroll operation, the distance at which the content images displayed on the screen are moved may be determined according to the speed or distance of the scroll operation. After the distance is moved, the movement of the content images is stopped.

In this case, as described above, the screen display time of the content images is determined to be proportional to the preference for the corresponding content, so that the image of the content with high preference is displayed on the screen 10 after the movement of the content images by the scrolling operation is stopped. As a result, the probability of being placed in a user selectable state may increase, and conversely, the probability of displaying an image of content with low preference may be relatively reduced.

Accordingly, the user may intuitively feel that the image of his or her favorite content is displayed and searched on the screen 10 with a high probability when scrolling, which makes it very easy to select a desired content among a large number of contents. Can be.

According to an embodiment of the present invention, the screen display time of the content images may be different according to the content preference by determining a moving speed of the content images moved in response to the scrolling operation according to the content preference. have.

For example, when the content images displayed on the screen are moved by the scrolling operation, the image of the content with low preference among the content images displayed on the screen moves at a high speed and disappears after being displayed on the screen for a short time, and has a high preference. The image of the content may move at a slow speed and disappear after being displayed on the screen for a long time.

Hereinafter, an embodiment of a method of adjusting the display time of content images according to preference will be described with reference to FIGS. 5 to 8.

In the following embodiment, it is assumed that the preference for the content has a value of '1' to '5', and the preference is high as the preference value increases. In addition, when the preference for the first content is '1', the preference for the second content is '5', the preference for the third content is '4', and the preference for the fourth content is '1'. Assume

Referring to FIG. 5, when the user scrolls in the left direction while the first to fourth content images 21, 22, 23, and 24 are displayed on the screen 10, the first to fourth content images 21 are displayed. , 22, 23, and 24 move at the moving speed 'v' such that the leftmost first content image 21 disappears from the screen 10 as shown in FIG. 6, and the fifth content image 22 is removed.
