1 is a block diagram illustrating a playback apparatus 100 according to an embodiment of the present invention.

The playback apparatus 100 according to FIG. 1 includes an input unit 110 and a control unit 120.

Only the components related to the present embodiment are shown in the playback apparatus 100 shown in FIG. Therefore, those skilled in the art will recognize that other general-purpose components other than the components shown in FIG. 1 may be further included.

On the other hand, the playback apparatus 100 may include a PMP, a PDA, a laptop PC, a tablet PC, a PVR, an MP3 player, a smart phone, and the like, including a playback function as well as an IPTV, smart TV, It can be one.

The input unit 110 receives a user input. The user can control the playback apparatus 100 through the input unit 110. [ Specifically, it is possible to control on / off of the playback apparatus 100 or to control the playback state of the multimedia data.

The input unit 110 may be implemented as a button key or a touch screen. However, the input unit 110 may be configured to receive a signal output from a remote control infrared ray transmitter when the remote controller can control the playback apparatus 100.

The control unit 120 controls the overall operation of the playback apparatus 100. Specifically, if there is no user input through the input unit 110 for a preset time, the controller 120 generates a signal for stopping the sound or video output of the user application.

Here, the user application refers to a program installed in an upper layer of an OS terminal of the playback apparatus 100 and using a lower kernel or system library through the framework. That is, the user application refers to a program capable of outputting sound or image to an application program facing the user directly.

If there is no user input for a preset time, the controller 120 determines that the user is no longer using the playback apparatus 100 and generates a signal for stopping the sound or video output by the user application.

For example, when the user enters the sleep state while listening to the sound source using the playback apparatus 100, a certain period of time may be maintained without any input. When a predetermined time has elapsed without any input through the input unit 110, the controller 120 determines that the user has entered the sleep state and blocks sound or video output by the user application.

As described above, when it is determined that the user has entered the sleep state, blocking the sound or video output by the user application can prevent the problems that may occur due to hearing loss, incomplete sleep, etc. have.

On the other hand, even though the user is not in the sleep state, no instruction is input to the playback apparatus 100 for a predetermined time, so that sound or video output by the user application may be interrupted regardless of the user's intention.

Accordingly, the playback apparatus 100 can provide a UI for setting the sleep time zone, thereby enabling the user to set the output disconnection time zone. Here, the output interruption time zone means a time when the user normally takes sleep. In this case, the control unit 120 can determine that the user has entered the sleep state if there is no user input for a preset time period, and the time when the user uses the playback apparatus 100 is the output blocking time zone set by the user.

As described above, when the user sets the output interruption time zone, it is possible to prevent the sound and video output by the user application from being interrupted regardless of the user intention.

Alternatively, a user command may not be inputted for a predetermined time, and the user may inquire whether to continue the output of sound or image before stopping the sound or video output by the user application. In this case, the playback apparatus 100 may further include a display unit, and the above-described UI may be displayed on the display unit.

For example, if a user command is not input for a preset time, the sound or video output by the user application is not immediately terminated, but a UI (User Interface: User interface).

If the user is not in the sleep state, the UI displayed on the display unit is checked. If the user responds to the command, the playback apparatus 100 performs an operation corresponding to the inputted command.

On the other hand, if the user has already entered the sleep state and can not confirm the UI displayed on the display unit, the control unit 120 displays the UI and stops the sound or video output by the user application after a predetermined time has elapsed .

As described above, if the sound or video output by the user application is interrupted according to the presence or absence of the user input to the UI of the inquiry, it is possible to prevent the sound or the image output from being interrupted .

According to another embodiment of the present invention, the playback apparatus 100 may further include a notification unit (not shown) for generating a warning sound when a preset time has elapsed.

The alarm generating unit (not shown) may generate a warning sound when there is no user input through the input unit 110 for a preset time. The beep sound may be a notification signal for stopping the sound and video by the user application because there is no user input for a preset time.

The control unit 120 may generate a signal for stopping the sound and image by the user application if there is no user confirmation input for a predetermined time after the alarm sound is generated.

According to another embodiment of the present invention, the reproducing apparatus 100 may further include an illuminance detecting unit (not shown) for measuring external illuminance. Normally, when the user enters the sleeping state, the illumination is turned off or the illuminance is lowered, so that the external illuminance is low. In this case, the controller 120 checks the external illuminance if a user command is not inputted so that the predetermined time elapses, and generates a signal to stop the sound and video output by the user application only when the illuminance is less than the threshold value .

Meanwhile, the illuminance sensing unit may be implemented by a camera module provided in a smart phone. However, it is not necessary to continuously operate the camera module while the sound and image are output by the user application. Since the external illuminance can be measured by operating the camera module just before a predetermined time elapses, excessive power can be prevented from being consumed by the operation of the camera module. In addition, since the camera module is mounted on both the front and back sides of a typical smart phone, the illumination and the video output by the user application are prevented from being interrupted as the illuminance measurement is performed according to the state in which the reproducing apparatus 100 is placed .

For example, the controller 110 generates a signal for stopping the sound and video output by the user application only when no user command is input for a predetermined period of time and all the illuminance measured by the two camera modules is less than the threshold value .

The reproducing apparatus 100 according to another embodiment of the present invention may further include an operation sensing unit (not shown) for measuring user movement. When the user enters the sleep state, the playback apparatus 100 may be in a stopped state. Accordingly, when the playback apparatus 100 is in a stopped state and there is no user input for a preset time, the controller 120 determines that the user enters a sleep state and generates a signal for stopping the sound and video output by the user application have.

Meanwhile, the above embodiments can be combined to control sound and video output by a user application. For example, in the case of controlling the sound and video output by measuring the external illuminance, if the user has put the reproducing apparatus 100 in the pocket bag, sound or video output may be interrupted by the user. Therefore, in order to cope with this case, it is possible to control the sound and image output by the user application by combining the embodiment for measuring the external illuminance and the embodiment for measuring the user's movement.

For example, if there is no user command input so that a predetermined time elapses, the controller 120 measures the external illuminance through an illuminance detector (not shown). If the external illuminance is less than the threshold value, the operation detecting unit (not shown) determines whether the reproducing apparatus 100 is in the stop state.

The controller 120 may generate a control signal for stopping the sound or video output by the user application when the user command is not input for a preset time and the external illuminance is less than the threshold value and the reproducing apparatus 100 is in the stopped state .

Needless to say, the preset time for waiting for the command input by the user can be changed by the user. For example, if there is no user command input for 30 minutes, a signal can be generated to stop the sound and video output, and the predetermined time may be set longer or shorter.

On the other hand, the above-described output control of sound and image of the user application can be controlled by an operating system (OS) installed in the playback apparatus 100. [ That is, since the audio and video output by the user application is controlled by the operating system installed in the playback apparatus 100, even if the above-described function is not included in the user application, if the user is determined to be in the sleep state, The control signal can be generated.

FIG. 2 is a diagram for explaining a UI for inquiring whether audio or video output is continued according to an embodiment of the present invention. Referring to FIG.

The playback apparatus 100 according to an embodiment of the present invention may further include a display unit 130. The display unit 130 may be implemented as an LCD, an LED, an OLED, or the like, and may support a touch screen function to perform an input unit 110 function.

The sound source information or the content image currently being reproduced may be displayed on the display unit 130. If the user command is not input so that the predetermined time elapses, a UI inquiring whether to continue the sound or video output may be displayed.

After the UI is displayed, if the user inputs a play stop command or there is no user input so that a predetermined time elapses, the control unit 120 may generate a signal to stop the sound and video output by the user application. That is, even though the UI about whether to continue the video output or not is displayed, it is highly likely that the user has entered the sleep state because there is no user input for a predetermined period of time. Therefore, the controller 120 controls the audio and video output by the user application It is possible to generate a signal to interrupt.

On the other hand, the UI inquiring whether to continue the sound or video output is not limited to that shown in FIG. 2, and can be implemented in various forms.

3 is a diagram for explaining a method of setting an output blocking time zone according to an embodiment of the present invention.

The user may feel somewhat uncomfortable if the user stops the sound and video output by the user application merely by not inputting the user command for a preset time. Therefore, the user can input the sleeping time, and if the user command is not input during the predetermined time in the corresponding time zone, the user can increase the convenience by blocking the sound and video output.

As shown in FIG. 3, the display unit 130 may display an output cutoff time window 140. FIG. The output interruption time input by the user is stored in a storage unit (not shown). If the user does not input the output interruption time, the control unit 120 can generate a signal to interrupt the video and audio output by the user application.

As described above, when the user sets the output interruption time zone, it is possible to more accurately determine whether or not the user has entered the sleeping state.

4 is a diagram for explaining how to generate a warning sound after a predetermined time has elapsed according to an embodiment of the present invention.

The playback apparatus 100 may further include a notification unit (not shown) for generating a warning sound if a user command is not input so that a predetermined time elapses.

The alarm sound generated by the alarm generator may be output through the speaker 140 provided in the playback apparatus. In this embodiment, the generated alarm sound is output through the speaker 140 provided outside the playback apparatus. However, the present invention is not limited to this, and the alarm sound may be output through the earphone worn by the user through the earphone terminal.

Alternatively, if the user uses a wireless type of earphone, such as Bluetooth or Wi-Fi, the user may transmit an audible alarm wirelessly.

When a warning sound is generated, the user can recognize that a user command through the input unit 110 has not been input for a preset time and input a confirmation command. In this case, sound or video by the user application is continuously output. On the other hand, when the user is unable to confirm the warning sound in the sleep state, the confirmation signal can not be input for a predetermined time, so that the control unit 120 generates a signal for stopping the sound or video output by the user application .

In addition, the reproducing apparatus 100 according to an embodiment of the present invention may further include an illuminance detecting unit 150. FIG. The illuminance detection unit 150 may be implemented as a camera module provided outside the playback apparatus 100. The controller 120 does not input a user command for a predetermined period of time and the external illuminance measured by the illuminance detector 150 is lower than the critical illuminance Value, it is possible to generate a signal to stop the sound and video output.

In addition, the reproducing apparatus 100 according to an embodiment of the present invention may further include an operation detecting unit (not shown).

The motion sensing unit may be implemented by an acceleration sensor or a gyro sensor or a combination thereof. The acceleration sensor is a sensor that measures the acceleration for each of the X, Y, and Z axes. Since the gravitational acceleration acts in the state where the sensor is stopped, it is possible to determine which axis is inclined. However, when the acceleration sensor is moving, it can be used with the gyro sensor because it can not know the exact tilt by the acceleration sensor alone. Unlike an acceleration sensor, a gyro sensor measures the angles of the X, Y, and Z axes and measures the angle of change. That is, the acceleration sensor is responsible for "speed, position" and the gyro sensor is for "direction".

The control unit 120 can generate and output a signal for stopping the sound or video output of the user application when it is determined that the user command is not inputted for a preset time and the reproducing apparatus 100 is stopped.

5 is a flowchart illustrating a method of controlling a playback apparatus according to an embodiment of the present invention.

The operating system installed in the playback apparatus 100 detects sound or video output by the user application in operation S510. If there is no user input during the predetermined time, the operating system generates a signal for stopping sound or video output by the user application (S520).

As described above, since the audio and video output by the user application is controlled by the operating system installed in the playback apparatus 100, if it is determined that the user has entered the sleep state even though the above-described function is not included in the user application, An effect of generating a control signal for stopping the output can be achieved.

6 is a flowchart illustrating a method of controlling a playback apparatus according to another embodiment of the present invention.

The operating system installed in the playback apparatus 100 detects sound or video output by the user application (S610). If the user command is not input for a preset time period (S620), it is determined whether the current time corresponds to the output blocking time zone set by the user (S630).

Thereafter, if it is determined that the time is not the output interruption time zone set by the user, the sound or video is continuously output, and if it corresponds to the output interruption time zone, a warning sound is output (S640). If an acknowledgment signal is input from the user within a predetermined time after the occurrence of a warning sound, sound and video are continuously output. If the confirmation signal is not input, the user determines that the user is in a sleep state, (S660). ≪ / RTI >

In the present embodiment, it is described that the sound output and the video output by the user application are controlled by generating the output cutoff time and the alarm sound set by the user, but it is also possible to control the reproduction apparatus 100 by combining other control methods.

7 is a view for explaining a playback apparatus 700 according to another embodiment of the present invention. The playback apparatus 700 using voice data according to an embodiment of the present invention may include the configuration shown in FIG.

Specifically, the playback apparatus 700 includes a processor 710 that executes instructions, a memory 720, an operating system that controls the playback apparatus, a storage device 730 that stores audio and video output user applications, And a network interface (NIC) 740 for data transmission / reception with the network.

The storage device 630 may store an operating system that detects a sound or video output from the user interface and generates a signal to stop the sound or video output if a user command is not input so that a predetermined time elapses. In addition, the above-described program may be loaded into the memory 640 and then executed through the processor 620. [

Meanwhile, the above-described method can be implemented in a general-purpose digital computer that can be created as a program that can be executed by a computer and operates the program using a computer-readable recording medium. In addition, the structure of the data used in the above-described method can be recorded on a computer-readable recording medium through various means. The computer-readable recording medium includes a storage medium such as a magnetic storage medium (e.g., ROM, floppy disk, hard disk, etc.), optical reading medium (e.g., CD ROM,
