1 to 9 describe a method of providing information by IPTV and IPTV according to an embodiment of the present invention.

1 is a diagram illustrating an IPTV broadcasting system related to an embodiment of the present invention. The IPTV broadcasting system refers to a system that provides a digital broadcasting signal received from a network to a user through IPTV.

The IPTV broadcasting system according to an embodiment may be configured with a remote control device 100 and an IPTV 200 as shown in FIG. 1A. The IPTV 200 may be connected to an external network by wire or wirelessly to receive digital broadcasting, and may provide a broadcast signal such as video on demand (VOD) or real-time broadcasting to a user. Meanwhile, the remote control device 100 may control the IPTV 200 by transmitting various control commands for the IPTV 200. For example, the remote control device 100 may control the IPTV 200 through various types of control commands such as channel change, volume control, and item selection.

Meanwhile, the IPTV broadcasting system may include a remote control device 100, a digital broadcasting receiver 150, and an IPTV 200, as shown in FIG. 1(b). The digital broadcast receiver 150 is connected to the remote control device 100 and the IPTV 200, receives digital broadcasts, converts them into broadcast data, and provides them to the IPTV 200. The digital broadcast receiver 150 according to an embodiment may include a set top box (STB) of the IPTV 200. The remote control device 100 may directly control the IPTV 200 as described above, and may indirectly control the IPTV 200 by transmitting a control command to the digital broadcasting receiver 150.

2 is a diagram illustrating a prior art in connection with the present invention. In the technology of controlling an IPTV using a remote control device, various methods of selecting an item 15 by moving a cursor on the screen 10 by sensing movement of the remote control device have been proposed. Meanwhile, “item 15” may refer to an object that is displayed on the screen 10 and is selectable.

As shown in FIG. 2, as the user moves the remote control device, the cursor or pointer displayed on the screen 10 of the IPTV moves from the position 30a to the position 30b. On the other hand, in order to select the items 15 arranged in various directions up, down, left and right, not only the user needs to precisely manipulate the remote control device, but also the cursor on the background space 20 other than the items 15 to be selected. B Because the pointer has to move, the user is burdened with inefficient and inconvenient operation.

3 is a flowchart illustrating a method of providing information on an IPTV according to an embodiment of the present invention.

In the IPTV information providing method for solving the above-described problem, in step S310, a focus movement command is received from a remote control device. The “focus movement command” may mean a control command for moving the focus for any one of items arranged and displayed on the screen.

First, “focus” refers to a GUI (Graphical User Interface) for indicating the currently selected item among several items. Referring to FIG. 6 as an example, a bold frame of the currently selected item 640 among a plurality of items 630 displayed on the screen may indicate “focus”. That is, the “focus movement command” is a control command from a remote control device that attempts to move a focus, which is a GUI element displayed on a currently selected item among items on the screen, to another item.

Specifically, as will be described later in FIG. 5, the focus control command may include movement information and rotation information of the remote control device, and may be received as data indicating a movement/rotation of the remote control device. Meanwhile, the focus control command may be directly received from the remote control device or may be received from the remote control device through a digital broadcast receiver.

In step S330, the IPTV determines a movement path to move the focus based on the focus movement command. The focus control command for moving the focus on a specific item includes information on movement/rotation of the remote control device as described above. Specifically, the information on the movement may include information on the amount of movement of the remote control device and information on the movement speed measured by the acceleration sensor of the remote control device, and the information on rotation is included in the gyro sensor of the remote control device. It may include information on the rotation amount and rotation speed of the remote control device measured by.

Accordingly, in step S330, the IPTV analyzes values of movement and rotation of the remote control device to determine a movement path to move the focus. The moving path may mean a two-dimensional path for items arranged in two dimensions on the screen of the IPTV.

According to an embodiment, in determining a movement path, all of the information on the movement amount and the movement speed, and information on the rotation amount and the rotation speed may be used. Basically, the larger the values for the amount of movement and the speed, the longer the movement path is determined, and the larger the value for the amount of rotation and the rotation speed, the larger the rotation angle of the movement path.

However, even if the measured movement amount is a large value, when the value for the movement speed is relatively small (that is, when the remote control device slowly moves a large distance), the IPTV value for the movement speed is large for the same movement amount. It is possible to determine a shorter travel path. Likewise, even if the information on the rotation amount included in the focus movement command is a large value, if the rotation speed is not fast, the IPTV can rotate the movement path at a relatively small angle. That is, the movement path may be determined not only by the movement amount and the rotation amount, but also by considering both the movement speed and the rotation speed.

Subsequently, in step S350, the IPTV discontinuously moves the focus along the moving path. Specifically, the IPTV moves the focus along items located on the movement path, and movement along the movement path is performed in units of items arranged and displayed on the screen. Accordingly, unlike the continuous movement of the cursor or the pointer as described in FIG. 2, the focus in the present exemplary embodiment moves discontinuously along the items. Specifically, it will be described with reference to FIGS. 6 and 7.

4 is a flowchart illustrating a method of providing information related to another embodiment of the present invention. In FIG. 4, step S350 of FIG. 3 will be described in detail, and detailed descriptions of steps S310 and S330 overlapping with those described in FIG. 3 will be omitted.

In step S410, the IPTV moves the focus along the movement path determined in step S330. According to an embodiment, movement according to the movement path may be performed from the center of an item whose focus is initially located. Specifically, after the movement path of the 2D coordinates is determined, the IPTV may discontinuously move the focus along the movement path determined in step S330 using the center position/coordinate of the currently focused item as a starting point.

In step S420, while moving the focus along the movement path, the IPTV determines whether there is a position without an item on the movement path. For example, if the item is located in close contact without a blank space between the item, the focus can be moved along the movement path, but if the item and the item are located apart from each other, the process of processing the space between the items Is required.

If there is a point or location where there is no item on the movement path, in step S430, the IPTV finds an item closest to the location. If the item found in step S430 is the item currently in focus, the IPTV does not move the focus in step S440. However, if the item found in step S430 is not the item currently in focus, the IPTV moves the focus to the item found in step S430 in step S450.

Referring to steps S420 to S450 as an example of FIG. 8, in the process of moving the focus from left to right along the movement path 830, the item 810 and the item 820 are located spaced apart from each other, so that a space exists between the items. do. Specifically, the section 840 and section 850, which are points where the focus deviates from the right border of the item 810, is described in detail. The item closest to the points corresponding to the section 840 is the item 810 where the focus is currently located, and points corresponding to the section 850 are The nearest item is an item 820 that does not have a focus.

Accordingly, while moving the focus along the movement path 830, in the process of processing the section 840, the focus is not moved and is positioned on the item 810 as it is. When the section 850 passes through the section 840, the focus is transferred from the item 810. Move to item 820. Accordingly, even when a space exists between items, the focus can be discontinuously moved in units of items.

5 is a diagram illustrating a process of detecting a motion of a remote control device according to an embodiment of the present invention. As described above, the focus control command may include movement information and rotation information of the remote control device so that the IPTV can determine the movement path.

It has been described above that the remote control device 100 may include an acceleration sensor and a gyro sensor. The acceleration sensor detects movement in the three axis directions of the x-axis 510, y-axis 520, and z-axis 530 of the remote control device, and can detect both a movement amount and a movement speed. The gyro sensor detects the rotation 540 of the remote control device, and similarly, can detect both the rotation amount and the rotation speed. The remote control device 100 may transmit a focus movement command including movement information and rotation information generated using an acceleration sensor and a gyro sensor to the IPTV.

Meanwhile, since items and movement paths arranged on the IPTV can be arranged according to two-dimensional coordinates as described above, the acceleration sensor of the remote control device 100 detects only movement in two of the three axis directions. You can also generate movement information. However, unlike the illustrated contents, items may be arranged on the screen of the IPTV according to 3D coordinates in space, and in this case, the acceleration sensor may detect movement along all three axes.

6 is a diagram illustrating an embodiment of setting a moving path according to an embodiment of the present invention. In the embodiment illustrated in FIG. 6, a case where the remote control device moves from position 610 to position 620 as shown in the lower part of FIG. 6 will be described as an example.

The IPTV 200 receives a focus movement command indicating movement and rotation of the remote control device moving from the position 610 to the position 620, analyzes the focus movement command, and determines a movement path 650. Meanwhile, the IPTV 200 displays a plurality of items 630 on the screen, and the items are arranged and displayed on two-dimensional coordinates of the top, bottom, left and right.

Since the current focus is located on the item 640, the IPTV 200 moves the focus from the center 660 of the item 640 along the movement path 650. The IPTV 200 discontinuously moves the focus along the items located on the movement path 650, and in the illustrated embodiment, the focus may be sequentially moved from the item 640 to two items located on the right side. In addition, the IPTV 200 may discontinuously move the focus in units of items along the movement path 650.

That is, the IPTV 200 first moves the focus to the item located on the section 670 of the movement path, and processes the section 680 according to the embodiment described in FIGS. 4 and 8 to move the focus to the next item. .

7 is a diagram illustrating an embodiment of moving a focus according to an embodiment of the present invention. 7 illustrates a result of moving a focus according to the embodiment described with reference to FIG. 6.

That is, the IPTV 200 sequentially and discontinuously moves and displays the focus from the item 710 to the item 720 and then to the item 730. Accordingly, the user can reduce the burden of precisely manipulating the remote control device by moving the cursor or the pointer over the space between the items, and can intuitively check the item to be selected and the currently selected item.

FIG. 8 is a diagram illustrating an embodiment of moving a focus according to another embodiment of the present invention, and has been described together with the embodiment described with reference to FIG. 4.

9 is a block diagram showing the configuration of an IPTV related to an embodiment of the present invention. The IPTV 200 according to the illustrated embodiment includes a communication unit 910, a movement path analysis unit 920, a display unit 930, and a control unit 940. Meanwhile, the configuration shown in FIG. 9 is only an example of implementation of the IPTV 200, and the IPTV 200 may be implemented with more or less configurations than the illustrated configuration.

The communication unit 910 transmits and receives various types of information such as inputs, data, signals, and commands from the outside. For example, the communication unit 910 may receive a focus movement command for moving focus from a remote control device or a digital broadcast receiver.

The communication unit 910 may receive information by wire or wirelessly, and may include one or more communication modules for performing communication with external devices, servers, and networks. For example, the communication unit 910 is a wireless LAN, Wi-Fi, Bluetooth, Zigbee, Wi-Fi Direct (WFD), ultra wideband (UWB), infrared communication (IrDA, infrared Data Association), BLE (Bluetooth Low Energy), NFC (Near Field Communication) and other wireless communication technologies can be used, and wired such as pair cable, coaxial cable, fiber optic cable, ethernet cable, etc. Communication can also be performed through.

The movement path analysis unit 920 determines a movement path using movement information and rotation information included in the focus movement command, and overall processes a process of moving the focus according to the movement path. That is, the movement path analysis unit 920 processes the focus to move discontinuously according to the movement path in consideration of items displayed on the display unit 930, the current position of the focus, and the movement path.

Various embodiments in which the movement path analysis unit 920 determines the movement path and moves the focus discontinuously have been described above, and a detailed description thereof will be omitted.

Meanwhile, in the above, the movement path analysis unit 920 of the IPTV 200 analyzes the focus movement command to determine the movement path. However, unlike this, the focus movement command received from the remote control device is applied to the movement path. All information may be included and received. That is, the remote control device may generate information on a movement path using the detected movement information and rotation information, and transmit a focus movement command to the IPTV 200 by including only information on the movement path. In this case, the movement path analysis unit 920 skips the process of analyzing the movement path according to the movement information and the rotation information, and moves the focus according to the movement path information obtained from the focus movement command.

The display unit 930 displays and outputs information processed by the IPTV 200. For example, the display unit 930 may output real-time broadcasting or VOD according to a digital broadcasting signal, and may display a plurality of items and focus on the screen as described above. In addition, when the movement path analysis unit 920 moves the focus according to the movement path, the display unit 930 may move and display the focus according to the processed result.

Meanwhile, the display unit 930 includes a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a plasma display panel, It may be implemented in a form including at least one of a flexible display, a 3D display, and an electrophoretic display.

The control unit 940 controls the overall operation of the IPTV 200. For example, the control unit 940 may transmit the focus movement command received by the communication unit 910 to the movement path analysis unit 920, and reflect the result processed by the movement path analysis unit 920 to reflect the display unit 930 ) Can also be controlled to display focus.

According to the IPTV and IPTV information providing method according to the embodiment described above, the user can efficiently select items displayed on the screen of the IPTV by minimizing unnecessary movement, and can intuitively and quickly check the selected items. There will be.

In FIGS. 10 to 16 below, a remote control device of an IPTV and a method of controlling the IPTV by the remote control device are illustrated and described.

10 is a diagram illustrating an embodiment of activating a motion monitoring mode in connection with an embodiment of the present invention. The “motion monitoring mode” refers to a mode in which the remote control device 100 operates to detect movement and rotation of the remote control device 100 by using an acceleration sensor and a gyro sensor. When the motion monitoring mode is activated, the remote control device 100 measures the movement amount and movement speed of the remote control device 100 using an acceleration sensor, and uses a gyro sensor to measure the rotation amount and rotation speed of the remote control device 100. Can be measured.

Meanwhile, a monitoring activation area 115 for activating the above-described motion monitoring mode is set and displayed on the display unit 110 of the remote control device 100. The “monitoring activation area” refers to a predetermined area on the display unit 110 implemented as a touch screen, and may be defined as an area having a predetermined size, position, and shape. Meanwhile, the display 110 may change and display a color, brightness, saturation, and the like so that the monitoring active area is distinguished from other areas.

When the display unit 110 is implemented as a touch screen, the display unit 110 is used as an input unit in addition to an output unit. Accordingly, the display unit 110 may sense a touch input when the user touches a part of the body or the monitoring activation area using a stylus pen or the like. When a touch input to the monitoring activation area is detected, the remote control device 100 may activate a motion monitoring mode and start detecting the motion of the remote control device 100.

On the other hand, on the display unit 110, in addition to the monitoring activation area, an input corresponding to an enter button of a keyboard or a left click of a mouse or a region corresponding to an input for displaying a menu may be further set. For example, as illustrated in FIG. 10, the display unit 110 may detect a touch input received from a user with different intentions by setting and displaying the area 117.

11 is a diagram illustrating an IPTV control method according to an embodiment of the present invention.

The remote control device detects a touch input to the monitoring activation area in step S1110. The touch input may be a temporary tap input or a double tap input to the monitoring activation area, or may be a long tap input maintaining contact for a predetermined time or longer.

In step S1130, the remote control device activates the motion monitoring mode while the touch input is maintained. That is, the remote control device detects the motion of the remote control device while the touch input to the monitoring activation area is maintained, and when the touch input to the monitoring activation area ends, the detection of the motion is terminated. Accordingly, the remote control device can save battery by reducing power consumption for motion detection.

On the other hand, the remote control device according to an embodiment of the present invention does not end the motion monitoring mode even if the touch input to the monitoring activation area is terminated and is not detected when the touch input continues for more than a predetermined first time in step S1130. Can be maintained. That is, operating the remote control device while continuously touching a predetermined area on the display unit may cause inconvenience to the user. Accordingly, when a continuous touch input to the monitoring activation area for a predetermined time or longer is detected, the remote control device may continue to detect movement and rotation of the remote control device even if the touch is released.

In step S1150, the remote control device generates and transmits an IPTV control command. The IPTV control command may be a focus movement command described in FIGS. 1 to 9 above. That is, the remote control device generates a focus movement command by converting the movement information and rotation information detected through the movement monitoring mode in step S1130 into data, and transmits it as an IPTV control command to move the focus displayed on the screen of the IPTV. have. Meanwhile, the remote control device may directly transmit an IPTV control command to the IPTV, or may indirectly control the IPTV by transmitting it to a digital broadcasting receiver.

12 is a diagram illustrating an IPTV control method according to another embodiment of the present invention. In FIG. 12, step S1130 described with reference to FIG. 11 will be described in detail, and a description of a portion overlapping with that of FIG.

When a touch input to the monitoring activation area is detected in step S1110, the remote control device detects motion in step S1210 and checks whether the touch input continues for a first time or longer. If the touch input lasts longer than the preset first time, in step S1230, the remote control device continues to maintain the motion monitoring mode even if the touch input no longer exists. On the other hand, if the touch input does not last for the first time and is released, the remote control device performs a motion monitoring process only while the touch input is maintained in step S1250. That is, if a touch input is not detected, the remote control device ends the motion monitoring mode.

13 is a diagram illustrating an embodiment of activating a motion monitoring mode according to a touch input in relation to an embodiment of the present invention. In the graph 1300 shown in FIG. 13, the horizontal axis represents the passage of time, and the vertical axis represents the activation (1) or deactivation (0) of the motion monitoring mode.

The remote control device detects a touch input to the monitoring activation area at time t1. As described above, if the touch input is maintained for the first time period of the time period t1 to t2, the remote control device continues to maintain the motion monitoring mode even if the touch input is terminated at time t3.

Subsequently, the remote control device according to an embodiment is a power saving mode that cuts off power to the backlight of the display unit when the second time of the time period t3 to t4 passes after the touch input is no longer detected at time t3. Can operate as According to the present embodiment, the remote control device can further save power by cutting off the power of the display unit while maintaining the motion monitoring mode.

On the other hand, the remote control device continuously senses the movement of the remote control device in the time period t1 to t5, and generates and transmits an IPTV control command. However, when the third time from time t5 to time t6 elapses while the movement of the remote control device, that is, movement and rotation is no longer detected, the remote control device may end the motion monitoring mode. That is, the remote control device may determine that manipulation from the user is no longer detected and stop monitoring the movement.

14 is a diagram illustrating an embodiment of activating a low power monitoring mode in connection with an embodiment of the present invention. 14, as in FIG. 13, the horizontal axis represents the passage of time, and the vertical axis represents activation/deactivation of the motion monitoring mode.

The remote control device detects a user's touch input to the monitoring activation area at time t1 and activates the motion monitoring mode. Meanwhile, in the embodiment shown in FIG. 14, unlike FIG. 13, the touch input to the monitoring activation area is not maintained for the first time period t1 to t3 but is released at time t2. Accordingly, as the touch input is released at time t2, the remote control device does not continue to maintain the motion monitoring mode and ends at time t2.

Meanwhile, in the embodiment illustrated in FIG. 14, the remote control device terminates the motion monitoring mode and activates the low power monitoring mode. In the “low power monitoring mode”, when the remote control device includes a low-power microcontrol unit (MCU) to recognize specific events in addition to the AP (Application Processor) for driving the application, even if the operation of the AP is stopped, the low power Refers to a mode that detects the event by driving only the MCU.

In the present embodiment, the event detected by the MCU may mean that a movement or rotation of a threshold value or more for the remote control device is detected. That is, the remote control device may detect a user's behavior of re-operating or picking up the remote control device through the “low power monitoring mode”, apart from ending the motion monitoring mode and no longer detecting motion.

That is, at the same time as the motion monitoring mode ends at time t2, the remote control device activates the low power monitoring mode. Subsequently, when an event (movement or rotation) equal to or higher than a preset threshold is detected at time t4 during operation in the low power monitoring mode, the remote control device reactivates the motion monitoring mode at t4 to detect the motion again. Accordingly, the remote control device can minimize power consumption required to always detect a user's manipulation of the remote control device.

Meanwhile, the motion monitoring mode reactivated at time t4 is terminated when no motion is detected during the third time period t5 to t6, similar to the embodiment described in FIG. 13.
