However, it is not possible to control activation or deactivation of a specific multimedia source reproducer through manipulation of the multimedia source reproduction mode.

If the multimedia source playback mode is activated, the control unit determines whether the multimedia source playback unit is included in the web page (S30). That is, the control unit searches the web page to determine whether the multimedia source playback unit exists and, if so, where the multimedia source playback unit exists.

When the multimedia source reproducing unit is searched, the multimedia source reproducing unit is activated or deactivated according to the position (S40). A process of activating or deactivating the multimedia source reproducing unit will be described in detail with reference to FIG. 5B.

The control unit determines whether the multimedia source reproducing unit is located in the reproducing area (S42)

If the multimedia source reproducing unit is located inside the reproducing area (S44), the multimedia source reproducing unit is deactivated if the multimedia source reproducing unit is located outside the reproducing area (S46).

When the setting for activating or deactivating the multimedia source reproducing unit for the current reproducing area ends, the current state is maintained and it is determined whether or not the reproducing area is scrolled by the operation of the user. (S50) The multimedia source reproducing unit inside the reproducing area may be moved to the outside of the reproducing area or the multimedia source reproducing unit outside the reproducing area may be moved into the reproducing area. Therefore, it is continuously determined whether or not the playback area is scrolled, and it is checked whether or not any multimedia source playback part is positioned within the playback area.

6 and 7 illustrate operations of the mobile terminal according to the second embodiment of the present invention. Only the parts different from the first embodiment of the present invention will be described. The same reference numerals are assigned to the same parts and the reference numerals with "a" are appended to the changed parts.

As shown in FIG. 6, the mobile terminal 100a according to the second embodiment of the present invention may be provided with a volume-weighted reference position G. FIG. The volume weighted reference position G means a reference point for making the volumes of the specific multimedia source playback units S1 and S2 larger or smaller in relation to the plurality of multimedia source playback units S1 and S2. This will be described in more detail as follows.

The first and second multimedia source playback units S1 and S2 may be located in the playback region of the web page P. [ It can be seen that the first and second multimedia source playback units S1 and S2 are located adjacent to each other in the web page P according to the present embodiment. The volume weighted reference position G may be provided at a specific place in the reproduction area A by the user's operation or the operation of the control part (180 in Fig. 1). In this embodiment, the volume weighting reference position G is set to a line form in the stop of the reproduction area. However, the position at which the volume weighting reference position G is set is not limited to this, (G) may be a specific region that can be displayed in various shapes such as a square, a triangle, and a circle.

The controller (180 in FIG. 1) measures the distance between the volume weighted reference position G and the first and second multimedia source playback units S1 and S2.

The first distance L1 between the first multimedia source playback unit S1 and the volume weighted reference position G is greater than the second distance L1 between the second multimedia source playback unit S2 and the volume weighted reference position G, Is smaller than the second distance (L2)

The control unit 180 of FIG. 1 can adjust the volume of the first multimedia source reproducing unit S1 closest to the volume weighting reference position G to a larger value than the volume of the second multimedia source reproducing unit S2. If the volume of the first multimedia source reproducer S1 is significantly larger than that of the second multimedia source reproducer S2, the volume of the first multimedia source reproducer S1 is relatively large, The sound generated in the multimedia source reproducing unit S2 can be ignored, and the possibility of operator confusion is reduced. In addition, the second multimedia source playback unit S2 visually present in the playback area A can intuitively recognize that the volume is small but operates, so that the mobile terminal 100a is not suspect of failure or the like.

As shown in FIG. 7, the scroll 181 can be moved by a user's operation or the like. When the scroll 181 is operated, the web page P is moved, and accordingly, the portion to be displayed through the playback area A is moved. The third distance L3 between the first multimedia source playback unit S1 and the volume weighted reference position G is shifted between the second multimedia source playback unit S2 and the volume weighted reference position G As compared with the fourth distance L4. Therefore, the control unit 180 of FIG. 1 increases the volume of the second multimedia source playback unit S2 instead of decreasing the volume of the first multimedia source playback unit S1.

The distance between the volume weighted reference position G and the first and second multimedia source playback units S1 and S2 is linearly moved away or near by the operation of the scroll 181. [ Therefore, according to the second embodiment of the present invention, the volumes of the first and second multimedia source playback units S1 and S2 gradually increase or decrease in accordance with the movement of the scroll 181, so that the operator feels emotional satisfaction There is an additional effect that can be achieved.

8A and 8B are flow charts of the mobile terminals of Figs. 6 and 7. Fig.

As shown, the mobile terminal according to the second embodiment of the present invention is different from the mobile terminal according to the first embodiment of the present invention in the step of adjusting the playback volume of the multimedia source playback unit (S40a). The step (S40a) of adjusting the playback volume of the multimedia source playback unit will be described in detail with reference to FIG. 8B.

As shown in FIG. 8B, it is determined whether the multimedia source reproducing unit is located within the reproducing area (S42).

If the multimedia source playback unit is not positioned within the playback zone, the multimedia source playback unit is deactivated (S46).

When the multimedia source reproducing unit is located in the reproducing area, the distance between the volume weighting reference position and the multimedia source reproducing unit is calculated (S43).

When the distance between the volume weighted reference position and the multimedia source playback unit is calculated, the playback volume is increased as the distance between the volume weighted position and the multimedia source playback unit approaches (S45). That is, the volume of the multimedia source playback unit closest to the volume weighted reference position is maximized, and when the distance from the volume weighted reference position is increased, the volume is gradually reduced, thereby improving the operator's sense of operation and enhancing the emotion quality.

FIG. 9 is a flowchart of a mobile terminal according to a third embodiment of the present invention. Referring to FIG. 9, only portions different from the second embodiment of the present invention will be described. Quot; b "is appended to the modified portion and quoted with" b ".

As shown, the mobile terminal according to the third embodiment of the present invention is different from the second embodiment of the present invention in the process of adjusting the reproduction volume of the multimedia source reproducer (S40b).

Specifically, the mobile terminal according to the third embodiment of the present invention activates only the playback volume of the multimedia source playback unit closest to the volume-weighted reference position (S45b). That is, the sound is reproduced only through the multimedia source reproducing unit closest to the volume weighting reference position, and the reproduction of the remaining multimedia source reproducing unit is stopped. From this point of view, it is different from the second embodiment of the present invention in which the volume is changed according to the distance relative to the volume weighted reference position. According to the third embodiment of the present invention, only the specific multimedia source playback unit operates, thereby preventing the possibility of confusion to the user and preventing an excessive load from being generated in the control unit.

In the above-described embodiments, the case where the volume weighting reference position is stopped at a specific position has been described, but it is needless to say that the volume weighting reference position can be moved to another position of the reproduction screen by the operation of the operator or the control unit .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
