3 is a schematic flowchart 300 illustrating a process of implementing a WOL function in each device such as a terminal and a TV according to an embodiment.

First, it is assumed that hardware (mainboard, WiFi + MCU integrated module, etc.) is configured in the TV.

Set the TV's mainboard WOL function to ON. (S 301).

Based on the above setting, the WiFi and MCU integrated module is also set to ON. (S 302)

Next, turn on the router WOL function connected to the TV, access the router manager page, set the remote port and URL. (S 303, S 304)

After setting as above, the router accesses the router setting page (using IP or URL) by using the WOL terminal and transmits a packet to the router. (S305).

Subsequently, the sharing period connection operation is performed with the TV. That is, a wireless signal is transmitted from the router to the TV, and a wireless signal is received from the WiFi + MCU integrated module configured in the TV, and the command (Power ON) is transmitted from the MCU to the TV main board. (S 306, S 307, S308, S 309).

Power is applied to the TV through the control by the WOL function as described above. (S 310).

4 is a flowchart 400 illustrating key information matching between a terminal and a TV.

Through the key matching, the TV may recognize a key value input by the user through the terminal.

As shown in Figure 4, the user selects a key matching start at the terminal. (S 401)

Based on the selection, the control unit of the terminal clears the currently set key information value. (S403).

Thereafter, the key information value stored in the TV memory unit is controlled to be transmitted to the terminal. (S 405)

According to the operation, the terminal is set a new key information value that is compatible with or equal to the key information value of the TV. (S 407)

If the key code map of the terminal is cleared before the key code information value (map) is transmitted from the TV as described above, the key code map can be written in the terminal memory. However, if the key code map of the terminal is not cleared, In case of receiving the overwrite, only the changed part can be overwritten by comparing with the key value stored in the memory unit of the terminal.

Meanwhile, as another embodiment, key information of a TV may be matched based on key information of a terminal, and an operation related thereto may be implemented through related contents described in the embodiment.

In addition, the key value information of the different devices is stored in the memory unit of each device (TV, terminal, refrigerator, etc.) without having to perform the above operation for key matching. According to the present invention, the key information value of the device may be set.

Hereinafter, key matching between the TV and the terminal will be described in detail.

In general, the key map of a TV consists of:

       typedef enum_IrcommandType

IRKEY_0 = 0x50,

      IRKEY_1 = 0x49,

      IRKEY_2 = 0x55,

      IRKEY_3 = 0x59,

      IRKEY_4 = 0x4D,

      IRKEY_5 = 0x51,

      IRKEY_6 = 0x5D,

      IRKEY_7 = 0x48,

      IRKEY_8 = 0x54,

      IRKEY_9 = 0x58,

      IRKEY_100 = 0xff // no this key

      IRKEY_POWER = 0x46, //

      IRKEY_INPUT = 0x04, // source

      IRKEY_OSD_MENU = 0x07,

      IRKEY_OSD_LEFT = 0x06,

      IRKEY_OSD_RIGHT = 0x1A,

      IRKEY_OSD_UP = 0x52,

      IRKEY_OSD_DOWM = 0x13,

      IRKEY_OSD_OK = 0x0F,

IRKEY_PIP = 0x40,

IRKEY_TTx_REVEAL = 0x4F,

IRKEY_TTx_UPDATE = 0xOC,

IRKEY_TTx_HOLD = 0x00,

IRKEY_TTx_LIST = 0x10,

IRKEY_TTx_SUBCODE = 0x53,

IRKEY_TTx_RED = 0x47,

IRKEY_TTx_GREEN = 0x4B,

IRKEY_TTx_LIST = 0x57,

IRKEY_TTx_SUBCODE = 0x5B,

Therefore, in case 1) or case 2), the terminal matches a key based on key map information received from the TV, and then the TV can be controlled using the terminal key.

5 is a flowchart 500 of performing key matching by comparing key map information stored in a terminal with key map information received from a TV.

Referring to FIG. 5, the terminal receives the TV key code map information from a TV. (S 501).

The received key map information and the key map information stored in the terminal are compared with each other (S 502, S 503, S 504), and are set to the corresponding values if they are the same. Otherwise, the received key map information is received from the TV. Change key value and save. (S 505, S 506, S 507)

Based on the above, the terminal key and the TV key have been matched, and the terminal key button can control the TV.

At this time, the packet information transmitted to the TV when the menu key is pressed in the terminal is as follows.

TV
Device ID Mobile
Device ID Packet
Code
(0x02 Start Code IRKEY_OSD
MENU = 0x07 End code

The packet structure mentioned above is

a. TV Device ID: To identify whether the packet is coming from the TV. (Using TV Device ID sent from TV to Mobile at key matching step)

b. Terminal Device ID: ID of a transmitting device used to determine which mobile device a packet is received from a TV.

c. Packet Code: Displays the type of data to be transmitted (ex. Key map = 0x01, Key code = 0x02)

d. Start Code: Notifies the start of data

e End Code: Notifies the end of data

f. Load real data between Stard Code and End Code

6 is an operation flowchart 600 of transmitting data from a TV to a terminal in transmitting and receiving data between the terminal and the TV.

When the TV power is off, the user can turn on and key the TV using the terminal and WOL function. (S 601, S 603)

On the other hand, when the TV's display panel is OFF, the information of the last viewed channel remains on the mainboard of the TV main body, so that the channel is tuned and the resolution of the image of the last viewed channel using the information is used. Optimize it and send it to the terminal. (S 605, S 609, S 611).

On the other hand, when the TV panel is ON, the resolution of the TV screen image is optimized and transmitted to the terminal. (S 607, S 609, S 611)

7 is an operation flowchart 700 of transmitting data from a terminal to a TV in transmitting and receiving data between the terminal and the TV.

First, when the TV power is off, the user turns on and key-matches the power using the terminal and WOL function. (S 701, S 703)

When the display device (Panel) of the TV is OFF, the panel on switch request message pops up the display device of the terminal. Accordingly, when the user wants to keep the panel in the OFF state, there is no display and there is no further progress. Therefore, the user refuses to receive the data and / or maintains the current OFF state. (S 705, S 713)

On the other hand, when the display device (Panel) of the TV is in the ON state, the reception of the terminal screen is popped up (S 707), based on the result of rejection of data from the terminal or / and maintains the current off state (S 707). 707 and S 715), the screen of the TV panel is switched to the screen received by the terminal by optimizing the resolution of the data received from the terminal. (S 709, S 711)

When the TV Panel is ON, the terminal screen is transmitted to the TV, and the TV may adjust the screen popup message and / or resolution after receiving an image.

As described above, it can be seen that data can be transmitted and received between the terminal and the TV.

In addition, as shown in Table 1-6, the keypad value of the terminal is mapped to the remote controller key value. When the keypad of the terminal is pressed, the corresponding value is transmitted as a packet to the TV and the TV performs an operation accordingly. do.

For example, if you press the Menu button on the terminal keypad, the TV turns on the Menu screen and displays the Menu OSD on the terminal.

     In implementing the present embodiment, a WOL dedicated screen (pop-up, etc.) in a TV may be configured. When the TV is turned on by WOL, unlike the general ON, by displaying the contents with a dedicated screen, only the necessary functions can be driven to increase CPU operation efficiency and reduce power consumption.

   The control apparatus and method of the display system according to the above embodiment may be implemented and applied in all different devices in which the display apparatus is configured.
