The present invention relates to a multimedia data reproducing apparatus for providing a predetermined object, and more particularly, to a device and a method for notifying a moving direction of an object using sound.

UI applications of embedded systems such as digital TVs have conventionally had only system-dependent resident applications. Currently, UIs such as Java applications or HTML downloaded over a network are available. Applications are also included, and in terms of their utility, the range of applications is reusable and one-off.

This development can provide a variety of UI use environment and selection to the user, while having a new menu every time a user accesses a new UI application.

In particular, in an embedded system situation in which the UI menu needs to be operated using only up, down, left, and right arrow keys without a mouse device, it is difficult for a user who is new to the application to recognize the menu and its usage.

In the current application, when the user selects the up, down, left, and right keys, the application is first touched and the result may not be recognized at a glance, or when the TV system is low specification or the application is complicated, the delay time when moving the menu is determined. Therefore, the user may be mistaken as not performing an operation.

HAVi level2 UI API (hereinafter referred to as HAVi UI API) is based on Java AWT and supports remote control interface suitable for embedded system environment. In particular, the position of the selector may be switched using up, down, left, and right arrow keys between the objects where the selector is located.

1 is a view showing an object provided in a conventional digital TV.

As shown, there are movable objects 10 on the screen of the digital TV, and each of the objects 10 may move the selector to other objects around by using up, down, left and right arrow keys. have.

For example, if one of the up, down, left, and right direction keys is selected after a specific object is activated, a new object existing in the corresponding direction is activated (that is, the selector is moved to the new object). Here, the application of the digital TV supports an API that enables the movement between the movable objects by using the direction keys, wherein the application programmer through the API, the upper and lower, Register an object that can move in the left and right directions.

 2 is a diagram illustrating an association relationship between movable objects included in an object in a conventional digital TV.

As shown in the drawing, object 1 registers information on surrounding objects that can be changed by a selector such as (object 2, object 3, none, object 4) with respect to the moving direction (up, down, left, right). The object 2 has information about neighboring objects which can be switched by a selector such as (none, object 1, object 5, object 4) with respect to the moving direction (up, down, left, right).

 First, when the user presses the 'Up' key with the remote controller while the selector is positioned on the object 1, the application system obtains the object 2 from the surrounding object information registered in the object 1 and selects the object as the object 2 as described above. Move the position of. In addition, the object 1 is changed to a state where the selector is not displayed, and a new UI is provided on the object 2 where the selector is located.

Thereafter, when the 'up' key is pressed on the object 2, since no navigable object corresponding to the direction exists, no operation is performed.

Next, pressing the 'down' key on the object 2 obtains the object 1 from the information registered in the object 2, the selector is located on the object 1 again.

However, because the object is moved with up, down, left, and right keys, even if the application is slightly complicated, the movable object cannot be immediately recognized from the currently active object. For this reason, there is a problem that the user takes a long time to learn how to operate the menu in the application.

In addition, in the case of an application that the user can continue using after learning the menu operation method once, only an initial effort to acquire the operation method is required. However, since there are many one-time download applications such as a digital TV, There is a problem that it is difficult to learn.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, it is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It is intended that the disclosure of the present invention be limited only by the terms of the appended claims. Like reference numerals refer to like elements throughout.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a block diagram of an apparatus for notifying a moving direction of an object using sound according to an embodiment of the present invention. Herein, the present invention uses an application that uses the HAVi UI API among UI applications downloaded from the multimedia data reproducing apparatus 100, and the HAVi UI API sets up a box to operate the download application in the multimedia data reproducing apparatus 100. (Setbox) and the middleware entering the multimedia data reproducing apparatus 100.

As shown, the multimedia data reproducing apparatus 100 includes an input unit 110, an operation determination unit 120, an operation processing unit 130, a storage unit 140, an output unit 150, a display unit 160, and a controller. And 170. Here, the multimedia data reproducing apparatus 100 refers to, for example, a digital television (TV), a digital multimedia broadcasting (DMB) receiving apparatus, a portable multimedia player (PMP), or the like.

The input unit 110 receives a key signal generated from the user. Here, the user operates a remote controller, a keyboard and a mouse to generate a predetermined key signal (operation command).

The operation determiner 120 determines an operation command according to a key signal generated by the user. Here, the operation command refers to requesting change to a predetermined channel and movement of a selector located on a specific object.

The operation processor 130 processes the operation command according to the determination result of the operation determiner 120. Here, the processing of the operation command may be performed when the user requests the movement of the selector located on a specific object by using a direction key, when a channel change is requested by using a predetermined function key, and when a user selects a predetermined function by using a predetermined menu key. When requesting an operation (for example, adjusting a volume or selecting a menu), this refers to processing an operation corresponding to the operation.

For example, when a user requests the movement of a selector located on a specific object by using a direction key, the operation processor 130 searches for a subroutine of information on the object where the selector is located in the storage 140 and selects the selector. Check if the object is switchable. Here, the operation processor 130 may determine whether the object is a switchable object based on the parameter value applied to the subroutine of each object.

That is, it is possible to determine whether the object can be switched between selectors based on up, down, left, and right values (setselecterNavigable (up, down, left, right)) applied to the subroutine of the predetermined object.

For example, if a parameter applied to the subroutine of Object 1 is checked and myComp.setselecterNavigable (a, b, null, null), the selector located on the first object can move upward and downward, It can be seen that it is not moved in the direction and the right direction. Here, the parameters (a, b, c, d) represent up, down, left and right directions.

Next, when the direction of the input direction key is a movable direction, the operation processor 130 moves the selector to another object located in the corresponding direction, and if the direction is not possible, the operation processor 130 confirms a predetermined operation. Outputs a note (e.g. alert sound). This allows the user to recognize that there is no movable object. On the other hand, if the selector can move in the corresponding direction according to the user's arbitrary setting, a predetermined confirmation sound may be output. If the selector does not move in the direction, the predetermined confirmation sound may not be output.

In addition, when a channel change request is made using a predetermined function key, the operation processor 130 processes an operation for changing a channel, and an operation of a predetermined function (for example, volume control and menu selection) using a predetermined menu key. Etc.), the operation processor 130 processes the operation.

The storage 140 stores information about objects provided to the multimedia data reproducing apparatus 100, and movable direction information about each object. That is, it stores the operation information of each object displayed on the screen of the multimedia player 100 and the connection information with the objects located in the periphery thereof.

When the output unit 150 requests the movement of the selector located on the predetermined object from the user, a predetermined confirmation sound (for example, a 'beep' sound according to whether the selector searched by the operation processor 130 can be switched) is output. )

The display 160 displays a plurality of objects, a selector, and predetermined multimedia data on the screen of the multimedia player 100.

The controller 170 sets a case where a confirmation tone is output (for example, when the selector can be moved or when the selector cannot be moved) according to a user's arbitrary setting request input through the input unit 110.

In addition, the controller 170 controls the operations of the respective functional blocks 110 to 160 constituting the multimedia data reproducing apparatus 100.

Herein, the term " part " used in the present embodiment means a hardware component such as software or an FPGA or an ASIC, and 'part' performs certain roles. However, 'part' is not meant to be limited to software or hardware. '~ Part' may be configured to be in an addressable storage medium or may be configured to play one or more processors. Thus, by way of example, 'parts' may refer to components such as software components, object-oriented software components, class components and task components, and processes, functions, , Subroutines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables. The functions provided in the components and components may be further combined with a smaller number of components and components or further components and components.

4A and 4B are diagrams illustrating a UI screen in an apparatus for notifying a moving direction of an object using sound according to an embodiment of the present invention.

As shown in FIG. 4A, when a user selects a predetermined direction key (for example, an upward direction) to move the selector 20 positioned on a predetermined object, the operation processor 130 may determine that the selector 20 is positioned. The information on the selected object is searched to check whether the selector 20 is switchable.

Next, when it is possible to move in the direction (eg, upward direction) of the input direction key as a result of the check, the selector is moved to another object located in the corresponding direction. Thus, since the warning sound is not output, the user may predict that the selector 20 is moved in the direction of the input direction key even when the selector 20 is not immediately moved due to a delay time during menu movement.

Next, as shown in FIG. 4B, the selector 20 is positioned on a predetermined object (eg, <) according to a user's upward key input.

Thereafter, when the user selects a predetermined direction key (for example, a left direction) to move the selector 20 positioned on the object, the operation processor 130 may determine the position of the object where the selector 20 is located. The information is checked to check whether the selector 20 can be switched.

Then, when it is not possible to move in the direction (for example, the left direction) of the direction key input as a result of the check, a predetermined confirmation sound (for example, a warning sound) is output. Thus, the user can immediately recognize that the selector 20 cannot be moved in the corresponding direction.

5 is a flowchart illustrating a method of notifying a moving direction of an object by using a sound according to an embodiment of the present invention. Here, it is assumed that a predetermined confirmation sound (for example, a warning sound) is output when the selector 20 does not move in a predetermined direction.

First, when a key signal generated from a user is input through the input unit 110 (S510), the operation determination unit 120 determines an operation command according to the input key signal. Here, the operation command is a command for requesting the movement of the selector 20 located on the specific object 10 by using the input key signal, a command for requesting a channel change using a predetermined function key, and a predetermined menu key. Refers to a command for requesting an operation of a predetermined function (for example, volume control, menu selection, etc.).

As a result of the determination, when the operation command is a command for requesting movement of the selector 20 located on the specific object 10 using the direction key (S520), the operation processor 130 may determine the object where the current selector 20 is located. The subroutine is searched among the information of (10) to check whether the selector can be switched (10) (S530).

When the selector 20 can be moved in the direction of the input direction key as a result of the check (S540), the selector 20 is moved to another object located in the direction corresponding to the input direction key (S550).

Next, the screen including the selector 20 located on the specific object is displayed on the multimedia data reproducing apparatus 100 through the display 160 (S560).

On the other hand, if the selector 20 cannot be moved in the direction of the input direction key as a result of performing the step S540, the control unit 170 via the output unit 150, a predetermined confirmation sound (for example, a warning sound) This is to be output (S570). Accordingly, the user may know that there is no other object that can move in the corresponding direction from the object where the selector 20 is currently located.

On the other hand, as a result of performing the step S520 is a command for changing the channel using a predetermined function key, or a command for requesting the operation (eg, volume control, menu selection, etc.) of the predetermined function using the predetermined menu key. In operation S580, the operation processor 130 performs the corresponding operation.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.

According to the apparatus and method for notifying the direction of movement of an object using the sound of the present invention as described above, there are one or more of the following effects.

By informing the user of the direction of movement of the object by using the sound, there is an advantage that can provide convenience in use.

In addition, since the API of the multimedia data reproducing apparatus is automatically processed, there is an advantage that the application programmer does not need to directly implement a function.

In addition, since it is only necessary to change the selector check algorithm internally while using the existing API specification, there is an advantage in that there is no overhead in API development for implementing the functions of the present invention.
