Description

How to automatically disable screensavers on all-in-one TVs and all-in-one TVs that run them {omitted}

The present invention relates to a PC integrated TV in which the functions of a PC and a TV are integrated. More particularly, the present invention relates to a method of automatically disabling a screen saver when a PC integrated TV is switched from a TV screen to a PC screen, and a PC for executing the same. It relates to an integrated TV.

TV has functioned as the center of home entertainment. However, the recent trend is that PCs are expanding to the center of home entertainment in response to the rapid arrival of the multimedia era. Increasing the computing power of the PC and the integrated signal processing ability of the digital digitization is increasing the importance of the PC as the center of home entertainment. The increase in the processing power of the PC is not simply achieved by improving the computing power of the central processing unit, but is due to the integrated signal processing ability due to the digitization of the multimedia data. For example, video decompression technology represented by Motion Picture Expert Group (MPEG) and voice compression decompression technology such as MP3 (MPEG Audio layer-3) are introduced, and a high-performance video controller and an audio controller capable of reproducing high quality and high sound quality. The integration of such hardware allows PCs to be used as the center of home entertainment.

The simplest example of using a PC as a center of home entertainment is when the PC is connected to a TV, and the video output of the PC is input to an external input terminal of the TV. In this case, the output of the video controller mounted on the PC is displayed on the TV screen, which is equivalent to using the TV as a monitor of the PC. The audio output of the PC can be connected to the AV speaker via a separate sound processing amplifier or to an active speaker with built-in amplifier.

Another form of development is a PC integrated TV. The PC integrated TV may enable an integrated operation in an advanced form as compared with the case where the image output of the PC is input to the external input of the TV. Through this, you can easily watch the video played through the PC through the TV screen or use the functions such as web-browsing through the PC.

As such, in the case of a PC-integrated TV in which the PC and the TV are integrated, the PC unit independently has files for system settings such as language, date, time, keyboard setting, and screensaver setting.

Screensaver is a software that automatically operates when the PC is not used for a certain period of time. On a PC that uses the original CRT as a monitor, the screen is easily focused because the electron gun behind the PC monitor focuses on one screen without the PC. It is to solve the problem of being damaged. The screensaver works automatically when no change is made to the screen for a certain period of time, dimming the screen or displaying a continuously changing graphic image. If the user operates the mouse at any key, the screen protection state ends and the previous work screen reappears.

Recently, a monitor of a PC is used such as a PDP or LCD, and accordingly, there is no problem when using a conventional CRT as a monitor. However, if the screen of the monitor is used as a fixed screen for too long, an afterimage may occur on the screen. In other words, in the case of CRT or PDP, the fluorescent material may be destroyed and the afterimage may remain. In the case of LCD, the afterimage may remain while the liquid crystal of the LCD panel is fixed. Therefore, an appropriate screen saver is employed even when using LCD or PDP as a monitor. Therefore, even in a PC integrated TV in which the PC and the TV are integrated, the PC unit operates the screensaver independently of the TV unit.

However, when the screen is switched from the TV screen to the PC screen, the screen saver screen is output when the PC is in the screen saver state. In this case, the user may switch from the TV screen to the PC screen and then use the mouse or the keyboard to exit the screen saver state again.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of automatically deactivating a screen saver when switching from a TV screen to a PC screen in a PC integrated TV and a PC integrated TV executing the same.

The dummy event signal is generated and transmitted to the PC unit. When the dummy unit receives the dummy event signal, the PC unit determines whether it is in a screen saver state, and deactivates the screen saver if it is currently in a screen saver state.

The dummy event signal may be any one of a keyboard signal and a mouse signal.

Here, the dummy event signal may be a signal promised to deactivate the screen saver in addition to the existing signals between the PC unit and the TV unit.

According to an aspect of the present invention, a method for automatically deactivating a screen saver when a PC screen is converted from a TV screen to a PC screen in a PC integrated TV including a PC unit and a TV unit includes: Generating a dummy event signal for deactivating a screen saver when the screen is switched from the screen to the PC screen, and transmitting the dummy event signal to the PC unit; determining whether the PC unit is currently in a screen saver state upon receiving the dummy event signal; If in a saver state, deactivating the screensaver.

The dummy event signal may be any one of a keyboard signal and a mouse signal.

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

1 is a block diagram showing the configuration of a PC integrated TV according to an embodiment of the present invention.

As shown in FIG. 1, the PC integrated TV 100 of the present invention is a main component, which includes a PC unit 110, a TV unit 120, an SMPS power unit 130, a remote control 140, and an interface unit. And 150.

Herein, the PC unit 110 includes a central processing unit (CPU) 112, a system chipset 113, and a D- mounted on the main board 111 around the main board 111. It may be configured to include a main memory 114, which is mainly used RAM, a secondary memory 115, which may be a hard disk (HDD) or flash memory (flash memory). Although not shown in FIG. 1, the PC unit generates a video signal and outputs a video signal, and an audio controller generates and outputs a 2-channel or multi-channel analog or digital audio signal. audio controller), and is generally mounted on the motherboard 111.

As the main board 111, various types of main boards may be adopted, but in general, an ATX (Advanced Technology Extension) board may be adopted, and in order to reflect the recent slimming trend, a mini-ATX board may be adopted. Will reduce the appearance size. ATX is an industrial open standard for mainboards of desktop computers, which can secure space to accommodate more expansion cards, and has a small number of cables and excellent cooling efficiency, so that the language setting changing device and method of the present invention can be applied. Suitable for slim characteristics of integrated TV.

In addition, in order to apply the apparatus and method for changing a language setting of the present invention, the main board 111 may be a main board having a soft on-off function. As the mainboard having such a function, the aforementioned ATX board can be adopted. When the ATX structure is provided, the power supply can be controlled step by step internally even when the main board is supplied from the outside. Rather than supplying power to the motherboard by a mechanical method, the supply and connection of power can be controlled under the control of the system chipset 113 in the motherboard. This is possible when an ATX board and an ATX power supply comply with the specifications of the ATX / ATX12V power supply.

As the CPU 112 mounted on the PC unit 110, when the PC unit is an IBM PC series, an Intel x86 series CPU or a CPU compatible with the x86 series may be adopted. The aforementioned system chipset 113 is a component that controls the entire PC unit 112 in terms of hardware. The main components of the PC unit 110 are main memory controllers, expansion slot interfaces, disk interfaces, keyboards and mice. It plays the role of interface, USB interface and so on. It usually consists of two (North Bridge: North Bridge, South Bridge) or three chips (MCH: Memory Control Hub, ICH: I / O Control Hub, FWH: FirmWare Hub) that perform different functions. Depending on the type of chipset may be configured differently. Recently, not only are the Northbridge chips and Southbridge chips integrated into one, but also the system processor chips of the all-in-one type video processor and audio controller are smaller and lighter. It is applied to many systems. For example, a system processor such as VIA's Cx700 / Cx700m may be used. Therefore, when using the integrated system processor described above, the system chipset 113, the video controller and the audio controller are embedded in one chip. In FIG. 1, the video controller and the audio controller are integrated into the system chipset 113, and according to the type of the system chipset 113, a configuration including a separate video controller and an audio controller may be possible.

D-RAM is generally used as the main memory 114, and recently, Double Data Rate-DRAM (DDR-DRAM) is applied. The auxiliary memory device 115 may be a hard disk or a flash memory device, and may be connected to the system chipset 113 through a parallel interface such as E-IDE (extended-IDE) or a serial interface such as SATA (serial AT attachment). do. Generally, a hard disk may be applied to the auxiliary memory device, but it may be advantageous to apply the flash memory device in terms of impact resistance, power consumption, and noise reduction. In addition, the auxiliary memory 115 may include an optical disc drive (ODD) such as a DVD-ROM, a DVD ± RW, a blue-ray, an HD-DVD, a CD-ROM, a CD-RW, and the like. It may also be connected to the system chipset 113 via interfaces such as E-IDE and SATA.

Meanwhile, the TV unit 120 includes a typical TV signal processor 121 for processing video and audio signals of a TV. The TV signal processor 121 is a component of a typical TV that plays a role of receiving a video signal and outputting it to a display panel in response to a TV signal format (for example, an analog signal such as NTSC, SECAM, PAL, or a digital TV signal). .

In addition, the TV unit 120 may include a controller 122 for processing the interface with the PC unit 110 and the internal control signals of the TV unit 120. Recent trends include a controller capable of processing remote control reception and generation of an OSD (On Screen Display) screen on a TV screen by mounting a TV signal processor 121 for processing a TV signal and firmware through predetermined programming ( In many cases, a one-chip solution is fabricated in a dual-core form in which 122 is included in one chip.

For example, such a case can be said of the VCT-Pro chip of the Swiss Micronas Inc., and has an 8-bit microcomputer (8051 compatible) as a TV signal processing unit 121 and a controller 122 for processing TV signals. . However, when the TV unit 120 is not implemented using the dual core chip provided by integrating the TV signal processor 121 and the controller 122 as described above, a separate configuration from the TV signal processor 121 is performed. It is possible to equip the controller 122 with a micom as an element.

The SMPS power unit 130 is a component that supplies power to the PC unit 110 and the TV unit 120. Switching Mode Power Supply (SMPS) has been widely used as a main power supply device because it is advantageous for miniaturization and high efficiency, which is suitable for light weight miniaturization of electronic products. SMPS power unit 130 is supplied with alternating current (AC) electricity of 110V or 220V and finally converted to various voltages (eg, + 12V, + 5V, + 3.3V) within a DC range of 3.3 to 48V to convert the TV unit ( 120 and the PC unit 110 is supplied. The SMPS power unit 130 supplies a current having a low voltage (for example, 5V) to the PC unit 110 and the TV unit 120 in a stand-by state. The power is applied to). Meanwhile, the SMPS power unit 130 may include additional additional components. For example, when the PC unit main board 111 is an ATX type main board, an ATX power board (ATX power board); 135). This is applied to the general PC because the PC integrated TV 100 to which the power management method of the present invention is applied, since both the PC unit 110 and the TV unit 120 are supplied with power from a common SMPS power unit 130. Unlike the case where the ATX SMPS power supply for the PC is to be used, the ATX power board 135 may be separately provided to convert the output of the SMPS power unit 130 to be supplied to the main board to fit the PC unit. have. Therefore, since the SMPS power unit 130 may be configured to include the ATX power board 135, it is shown in FIG. 1 using dotted lines to indicate that it is a separate additional component for convenience. According to another possible embodiment, there may be a method of independently configuring a separate SMPS power unit for each of the TV unit 120 and the PC unit 110, in which case the ATX power dedicated to the ATX motherboard for the PC unit. Supply may be applicable. At this time, the ATX power board 135 may be configured to be omitted.

The remote control 140 is a user interface device for operating the PC unit 110 or the TV unit 120, and is a device for receiving an operation command of the PC unit 110 or the TV unit 120 from a user. Although FIG. 1 illustrates the remote control 140, it is obvious that other user interface devices such as a wireless keyboard or a virtual keyboard implemented on a display (not shown) may be used.

The PC unit 110 and the TV unit 120 may be connected to each other through a predetermined interface unit 150. The interface unit 150 may be variously configured according to the embodiment, which may vary depending on the implementation of the system.

2 is a circuit diagram illustrating an example of a configuration of an interface unit between a TV unit and a PC unit of a PC integrated TV according to an exemplary embodiment of the present invention. 3 is a view for explaining the pin assignment of the 40-pin connector applied to the interface unit 150 of the PC integrated TV according to an embodiment of the present invention.

Referring to FIG. 2, it can be seen that a 40-pin universal connector may be applied to the interface unit 150 between the PC unit 110 and the TV unit 120 of the PC integrated TV 100 to which the language setting change device of the present invention is applied. The role of each assigned pin may be described with reference to FIG. 3.

However, in this case, the ATX board is applied as the main board 111 of the PC unit 110, and the system chipset 113 of the main board is an exemplary embodiment in which one kind of chipset (Cx700m) of VIA is applied. Although it depends in part on the input configuration of the VIA chipset, it will be apparent to those skilled in the art that similar pin assignments can be made when other system chipsets are applied.

For example, the interface unit 150 illustrated in FIG. 2 integrates a video signal, an audio signal, an Ethernet signal, a USB signal, and data and control signals between the PC unit 110 and the TV unit 120. It is configured to transmit.

Hereinafter, the main signal processed through the interface unit 150 will be described in more detail with reference to FIGS. 2 and 3.

First, signals 1 to 8 are USB interface related signals.

In the embodiment illustrated in FIG. 3 illustrates a case where a USB controller capable of controlling two USB input / output ports is mounted on the PC unit 110.

The USB input / output port provided in the TV unit 120 is composed of four lines each including a power line (5V, VBUS), two data lines (DATA +, DATA-), and one ground line (GND). It is connected to a USB controller (not shown) included in (110).

Next, the signals 9-14 and 16-19 are Ethernet controller related signals.

3 illustrates a configuration in which an Ethernet controller (not shown) mounted on the PC unit 110 and the TV unit 120 are connected by ten signal lines.

Of the 10 signal lines, six signal lines (ETHERNET_TXD +, ETHERNET_TXD-, ETHERNET_RXD +, ETHERNET_RXD-, ETHERNET1_GND, ETHERNET2_GND) are allocated as signal lines and ground lines for transmitting and receiving data.

Among the 10 signal lines, the remaining four (ETHERNET_3.3V, ETHERNET_LEDO, ETHERNET_LED1, and ETHERNET_LED2) are signal lines for controlling the LED (Light Emitting Diode) indicating the Ethernet connection status and data transmission / reception status. Typically, since the portion in which the input / output ports are mounted on the circuit board of the TV unit 120 is exposed to the outside from the housing of the PC integrated TV, the LEDs are also mounted on the circuit board of the TV unit 120 to the four signal lines. And to indicate an operating state of the Ethernet controller.

The signals 23, 24, 31, and 32 are communication signals between the system chipset 113 and the controller 122.

Signal lines 23 (RXD_SCL), signal lines 24 (TXD_SDA), signal lines 31 (DSUB_DATA), and signal lines 32 (DSUB_CLK) are signal lines allocated for communication between the PC unit 110 and the TV unit controller 122.

The RXD_SCL and TXD_SDA signal lines are signal lines for delivering a remote control reception signal generated by the controller 122 to a super IO controller (not shown) in the system chipset 113 of the PC unit 110. The DSUB_DATA and DSUB_CLK signal lines are An I2C interface line for a DDC (Display Data Channel) interface with a video controller (not shown) included in the PC unit 110.

Next, signals 27, 29, and 37 are power management signals.

Signal lines 27 (VIA_RESET_SW), signal lines 29 (VIA_ON / OFF_SW), and signal lines 37 (POWER_OK) are signal lines for integrated power management of the PC integrated TV 100 according to the present invention.

VIA_RESET_SW is a signal for resetting the PC unit 110. The VIA_RESET_SW is configured in a hard-wired form to receive an input of a reset button provided in a housing of a PC integrated TV, or from an operation menu of a PC integrated TV. When a predetermined reset menu is selected, an electrical signal generated through the TV controller 122 may be input.

The POWER_OK signal may be a power-good signal (“Power Good” signal; PWR_OK signal) according to the ATX power supply standard transmitted from the ATX power board 135 that may be included in the SMPS power unit 130. The OFF_SW signal is mapped to the power button input of the system chipset 113 (eg, the PWRBTN 'signal in the case of the VIA Cx700m chipset). The POWER_OK signal is a signal for checking the operation state of the PC unit 110, and the VIA_ON / OFF_SW signal is a signal for performing an operation for turning the PC unit 110 on and off, and the PC unit 110 and the TV unit 120. It is used for integrated power management operation.

Next, signals 28, 30, and 33 to 35 are video signals.

Signal line 28 (VIA_HS) and signal line 30 (VIA_VS) constitute a horizontal sync signal and a vertical sync signal of the video signal, respectively.

Signal line 33 (VIA_R_IN), signal line 34 (VIA_G_IN), and signal line 35 (VIA_B_IN) constitute R (Red), G (Green), and B (Blue) signals of the pixel. Input to the TV receiving processor 121 of 120 to configure the output screen of the PC (110).

Finally, signals 39 and 40 are audio signals.

Signal line 39 (VIA_AR_IN) and signal line 40 (VIA_AL_IN) constitute a two-channel analog audio signal. That is, in the embodiment illustrated in Table 1 illustrates a configuration for outputting a two-channel analog audio signal from the audio controller 117 of the PC unit 110, but also a configuration for outputting a 5.1-channel analog audio signal or a digital audio signal Will be applicable.

According to the configuration illustrated in FIGS. 2 and 3, it can be seen that the system chipset 113 integrates the functions of the video controller and the audio controller. For example, the VIA_HS, VIA_VS, VIA_R_IN, VIA_G_IN, and VIA_B_IN signals are video signals output from the video controller integrated in the system chipset 113, and the VIA_AR_IN and VIA_AL_IN signals are output from the audio controller integrated in the system chipset 113. to be. If you are not using a system chipset with integrated video and audio controllers, you may have a different configuration. For example, a signal output from a separate video controller or a separate audio controller that may be mounted on the main board 111 of the PC unit 110 may be mapped.

As such, the audio signal, the video signal, and the data from the PC unit 110 are transmitted to the TV unit 120 through the interface unit 150. As shown in FIG. 1, the TV unit 120 includes a display 125, and the controller 122 of the TV unit 120 may display a video signal transmitted from the PC unit 110 on the display. have.

Specifically, when the PC mode is selected by the user, the controller 122 of the TV unit 120 displays the video signal of the PC unit 110 provided through the interface unit 150 on the display 125.

In addition, the controller 122 of the TV unit 120 displays a video signal provided from the TV signal processing unit 127 on the display 125 when the TV mode is selected by the user. In this case, the TV unit 120 does not transmit to the PC unit 110 even if a keyboard or mouse signal is input from the user through the remote control 140. That is, when the TV unit 120 is currently in the TV mode, the remote control 140 may use a keyboard or mouse signal from the user to control a TV related function.

That is, the controller 122 of the TV unit 120 displays the video signal of the PC unit 110 provided through the interface unit 150 or the TV signal processing unit according to whether the current mode is the PC mode or the TV mode. It is determined whether to display the video signal provided from 127.

Therefore, in the PC integrated TV, the PC unit 110 continues to operate even when the screen of the deplay 125 is the TV screen. However, since the keyboard or mouse signal input through the TV unit 120 is not transmitted to the PC unit 110 when the current mode is the TV mode, the PC unit 110 determines that there is no input from the user for a certain time. The screen saver state can be entered accordingly. That is, since the PC unit 110 does not receive a signal from the user when the PC-integrated TV is in the TV mode, if there is no user input for a predetermined time after entering the TV mode, the PC unit 110 activates the PC screen saver and enters the screen saver state.

When the controller 122 of the TV unit 120 according to the present invention receives a signal for switching from the TV screen to the PC screen through the remote control 140, for example, the controller 122 switches to the PC screen. At this time, the controller 122 of the TV unit 120 generates a dummy event signal. The dummy event signal is a control signal forcing the PC unit 110 to leave the screen saver state. This dummy event signal deactivates the screensaver.

In another embodiment, the dummy event signal may be a keyboard signal or a mouse signal. The keyboard signal is a signal generated when a key is selected on the keyboard. The mouse signal may be a signal for moving the mouse pointer or a signal generated when a mouse button is clicked. According to the present invention, the dummy event signal is not limited thereto, and may be any signal that causes the PC unit 110 to forcibly leave the screen saver state.

The controller 122 of the TV unit 120 generates a dummy event signal and transmits the dummy event signal to the PC unit 110. Upon receiving the dummy event signal, the PC unit 110 determines whether the PC unit 110 is in a screen saver state. If the PC unit 110 is in the screen saver state, the PC unit 110 deactivates the screen saver.

As mentioned above, the screensaver is software that the PC executes if there is no input from the user for a predetermined time. Therefore, the PC unit 110 may deactivate the software to escape from the screen saver state.

Although described in the present embodiment with a limited screen saver, it will be apparent to those skilled in the art that the present invention can be applied even when the PC unit is in, for example, a low power mode.

4 is a signal flowchart illustrating a method of automatically deactivating a screen saver when a PC integrated TV is switched from a TV screen to a PC screen according to an embodiment of the present invention.

Referring to FIG. 4, according to the present invention, the TV unit 120 first determines whether a signal for switching from the TV screen to the PC screen is input through the remote control 140 in step S210. That is, the user may switch between the PC screen and the TV screen as desired through the remote control 140.

When the user inputs a signal for switching from the TV screen to the PC screen through, for example, the remote control 140, the TV unit 120 switches the display screen from the TV screen to the PC screen in step S220 (not shown), and the PC. The unit 110 generates a dummy event signal instructing to deactivate the screensaver.

The dummy event signal may be newly promised between the PC unit 110 and the TV unit 120 according to the present invention. That is, the dummy event signal may be newly promised and used in addition to the signals transmitted and received between the PC unit 110 and the TV unit 120.

In another embodiment, the dummy event signal may be a keyboard signal or a mouse signal. The keyboard signal is a signal generated upon selection of any key on the keyboard. The mouse signal may be a signal for moving the mouse pointer or a signal generated when a mouse button is clicked.

When the dummy event signal is a keyboard signal or a mouse signal, the TV unit 120 may generate a keyboard or mouse signal even when the keyboard or mouse signal is not input by the user when switching from the TV screen to the PC screen. This is because a typical PC disables the screen saver when a keyboard signal or a mouse signal is input in the screen saver state.

The TV unit 120 generates the dummy event signal and then transmits the dummy event signal generated in step S230 to the PC unit 110.

Upon receiving the dummy event signal, the PC unit 110 determines whether the screen saver is in the screen saver state at step S240. If the PC unit 110 is currently in the screen saver state, the PC unit 110 proceeds to step 250 to deactivate the screen saver.

Accordingly, the PC unit 110 may deactivate the software to escape from the screen saver state.

Although described with reference to the embodiments above, those skilled in the art will understand that the present invention can be variously modified and changed without departing from the spirit and scope of the invention as set forth in the claims below. Could be.
