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

1 is a block diagram of a PC integrated TV to which the power management method of the present invention is applied.

As shown in FIG. 1, the PC-integrated TV 100 to which the power management method of the present invention is applied is a main component and includes a PC unit 110, a TV unit 120, an SMPS power unit 130, and power-on. It may be configured to include an off signal input unit 140.

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 the mainboard of desktop computers, which can secure space to accommodate more expansion cards, has a small number of cables, and has excellent cooling efficiency. Suitable for slim features.

In addition, in order to apply the power management method of the present invention, the main board 111 should have 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 hardware. The core chipsets of the PC unit 110 include main memory controller, expansion slot interface, disk interface, keyboard and mouse. It plays the role of interface, USB interface, etc. 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 handling 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 in which the 122 is manufactured in a dual-core form included in one chip is provided.

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 the DC range of 3.3 to 48V to convert the PC unit ( 110) and the TV unit 120. 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 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 for power management; 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 power on / off signal input unit 140 may include a power button 141 or a remote controller receiver 142 and a remote controller 143 installed in the main body. The controller 122 of the TV unit may be configured to recognize a pressing operation of the power button 141 installed in the main body or the remote control unit 143 power button received by the remote control receiver 142.

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 view showing an example of the configuration of the interface unit between the TV unit and the PC unit of the PC integrated TV to which the power management method of the present invention is applied.

Referring to Figure 2, it can be seen that the 40-pin universal connector can 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 power management method of the present invention is applied. In addition, the role of each assigned pin can be described through Table 1.

However, here, 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 example of implementing one type (Cx700m) of the chipset of the VIA company is applied, Although it depends in part on the input configuration of the VIA chipset, it is 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.

Table 1 below is a diagram illustrating the pin assignment of the 40-pin connector applied to the interface unit 150 between the PC unit and the TV unit illustrated in FIG.

According to the configuration illustrated in FIG. 2 and Table 1, it can be seen that the system chipset 113 is an embodiment in which the functions of the video controller and the audio controller are integrated. 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.

Meanwhile, the pins allocated for the power management method of the present invention may be configured as pins named POWER_OK and VIA_ON / OFF_SW according to the above-described embodiments, or may be configured differently according to the implementation of the system. According to the above-described embodiment, the POWER_OK signal is mapped to a power-good signal (“Power Good” signal; PWR_OK signal) according to the ATX power supply standard output from the ATX power board 135, and the VIA_ON / OFF_SW signal is mapped to the system chipset. Input is via a power button input (eg, the PWRBTN # signal in the case of the VIA Cx700m chipset).

By power management method according to the present invention PC  Integrated TV  Power-on operation

3 is a flowchart illustrating a power-on operation of the PC integrated TV according to the power management method according to the present invention.

As shown in FIG. 3, in the power-on operation according to the power management method according to the present invention, the user presses the power button 141 included in the power on / off signal input unit 140 in the controller 122 of the TV unit. In operation S100, the remote controller 142 recognizes that the user has pressed the power button of the remote controller 143.

The SMPS power unit 130 is in a standby state as long as AC power is applied, and supplies a current having a low voltage (eg, 5V) to the PC unit 110 and the TV unit 120 even in the standby state. The power is applied to the controller 122 of the TV unit 120 to operate the controller 122 to transmit the power-on signal or power-off signal transmitted from the above-described power on / off signal input unit 1140. It is used to recognize and perform the necessary processing.

The controller 122 of the TV unit 120 recognizes the pressing operation of the power button and turns on the main power through the SMPS power unit 130, and the PC unit 110 by power-on of the main power source. ) And supply of power required for the operation of each of the TV unit 120 is started (S200). However, the TV unit 120 immediately starts operation by power-on of the main power supply. However, in the case of the PC unit 110, the power supply to the main board 111 is started. This is not disclosed. For example, when the power state of the PC unit 110 is classified into an Advanced Configuration and Power Interface (ACPI) power management class, the power state of the PC unit 110 is in a G2 state (soft off state).

The controller 122 of the TV unit spends a predetermined delay time (for example, about 5 seconds) for waiting for stabilization of the power supply, and then the PC unit 110 and the TV unit (at a predetermined time interval (for example, several ms intervals). The operation state of the PC unit 110 is checked through the interface unit 150 between 120 (S120). Next, a branch is made according to the operation state check result of the PC unit (S130). The operation state check of the PC unit 110 referred to herein is for checking whether the PC unit 110 is in a power-on state, and is confirmed by polling a predetermined pin connected to the PC unit at a predetermined time interval. This is possible. For example, by polling a predetermined pin (POWER_OK) of the interface unit illustrated in Table 2, it may be possible to check whether the main board 111 of the PC unit is operating. The predetermined pin (POWER_OK) of the interface unit 150 may be a power-good signal (“Power Good” signal; PWR_OK signal) transmitted from the ATX power board 135 may be mapped as an embodiment. In the example, the PWR_OK signal is an ATX power supply, i.e., a signal that the ATX power board 135 switches to a high state or a low state, and the + 12V DC power supply, + 5V DC power supply, It is a signal indicating whether the + 3.3V DC power is normally supplied, and thus, the operation state of the PC unit 110 can be checked by determining whether power is supplied to the main board 111 of the PC unit through this signal. .

When the controller 122 of the TV unit checks the operation state of the PC unit 110 at the predetermined time intervals described above, the controller 122 is the PC unit 110 when the PC unit 110 is already powered on. Confirms that the power is already on, and repeats the step S120 of checking the operation state of the PC unit again.

When the controller 122 of the TV unit checks the operation state of the PC unit at the predetermined time intervals described above, if the PC unit is not powered on, the controller 122 of the TV unit immediately returns power to the PC unit 110. Transmit the on signal (S140). The controller 122 of the TV unit powers on the PC unit by applying the VIA_ON / OFF_SW signals illustrated in Table 2 through the interface unit 150 between the TV unit and the PC unit. The VIA_ON / OFF_SW signal is delivered to the system chipset via a predetermined pull-up circuit. The input to the system chipset is determined according to the type of system chipset used. For example, in the embodiment using the aforementioned VIA Cx700m system processor, the power button input of the system processor (PWRBTN #, Cx700 series data sheet p. The system chipset sends a signal to the ATX power board to start the entire power supply (PS_ON # signal, the standard signal of the ATX power supply, and the low state because it is an active-low signal) (S150). ). Finally, the ATX power board 135 converts the power supplied from the SMPS power unit 130 into a voltage suitable for the PC unit 110 to supply the main board 111.

On the other hand, after the above steps to repeat the step (S120) to check the state of the PC main board again, that is, the TV controller 122 continuously checks the state of the PC main board mainboard If is not in the power-on state can be configured to perform the operation to power-on the motherboard.

By power management method according to the present invention PC  Integrated TV  Power- off  action

4 is a flowchart illustrating a power-off operation of the PC integrated TV according to the power management method according to the present invention.

As shown in FIG. 4, in the power-off operation according to the power management method according to the present invention, the user presses the power button 141 included in the power on / off signal input unit 140 in the controller 122 of the TV unit. In operation S200, the remote controller 142 recognizes that the user has pressed the power button of the remote controller 143.

The controller 122 of the TV unit recognizes that the power-off operation instruction has been issued by the user from the power on / off signal input unit 140 and performs the power-off operation of the PC unit 110. The operation of powering off the PC unit by the controller 122 of the TV unit is similar to the power-on operation described above. The VIA_ON / OFF_SW illustrated in Table 1 of the system chipset 113 is provided through the interface unit 150 between the TV unit and the PC unit. By applying a signal. The VIA_ON / OFF_SW signal is delivered to the system chipset via a predetermined pull-up circuit. The input to the system chipset is determined according to the type of system chipset used. For example, in the embodiment in which the aforementioned VIA Cx700m system processor is used as the system chipset 113, the power button input (PWRBTN #, Cx700 series data sheet (see p.37)).

Next, the operating system mounted on the PC unit 110 enters into a power saving mode preset by a power button input from the system chipset 113. Which power saving mode is to be set depends on the settings of the basic input / output system (BIOS) that manages the input / output of the main board 111 mounted on the PC unit 110 and the setting of the operating system mounted on the PC unit. do.

For example, in the power saving mode, one of S1, S3, and S4 may be used as the power saving mode on the ACPI power management class when ACPI power management is applied.

For example, the S1 power management grade is abbreviated as a power on suspend (POS) state, and power of input / output devices such as auxiliary storage devices (HDD, ODM) and a monitor is cut off while the PC unit 110 is turned on. In this state, the core parts such as the central processing unit and the main memory are operating normally.

Next, S3 power management class is abbreviated as STR (Suspend to RAM) state, only the contents of main memory (D-RAM) are preserved and most of the rest of the devices are powered off. The refresh operation of the main memory (D-RAM) is maximally understated and only + 5V DC power is supplied to power the D-RAM.

Meanwhile, the S2 power management class is an intermediate mode between S1 and S3, and the power to the central processing unit is cut off, but the refresh of the main memory (D-RAM) is normally performed.

Lastly, S4 power management class is abbreviated as STD (Suspend to Disk) state, and the state of the system is turned off after saving the contents of main memory (D-RAM) to the hard disk. If the system is turned on afterwards, the data stored in the hard disk is restored to the main memory (D-RAM) and restored to the state before entering the power saving mode.

Therefore, as described above, when the controller 122 inputs the power on / off signal VIA_ON / OFF_SW to the system chipset through the interface unit 150 between the PC unit and the TV unit by the TV power button operation. The installed operating system recognizes this and causes the PC unit 110 to enter into one of the power saving modes described above. However, when the BIOS setting of the PC unit and the operating system installed in the PC unit do not support the power saving mode or the power saving mode is set to not use the power saving mode, the soft-off is not the power saving mode. May also enter the state.

As described above, when it is set to support the power saving mode and use the power saving mode, the PC unit enters the power saving mode (S220). It offers clear advantages when the PC enters power saving mode. When the power-on operation for the PC unit is performed by the power management method according to the present invention described with reference to FIG. 3, when the TV controller performs power-on for the PC unit, the PC unit is operated by the operation of the operating system. Recovery from. This greatly reduces the boot time of the operating system required for power-on of the PC.

For example, when the boot time of the operating system, which takes several tens of seconds to several minutes, is recovered from the power saving mode, it is several seconds (S3; when recovering from the STR power saving mode) to tens of seconds (S4; when recovering from the STD power saving mode. Can be reduced to

When entering into the power saving mode by the operation of the operating system, the degree of power off of the motherboard is determined according to the entered power saving mode level. For example, when entering the S4 (STD) state, the power supply to the main board is cut off (except standby power supply, eg, + 5VSB power supply). In this case, the SMPS power unit sends a signal to the ATX power board 135 to stop supplying the entire power supply (PS_ON # signal, the standard signal of the ATX power supply, and the high-state signal as an active-low signal). Power supply to the PC main board 111 through the 130 is stopped. On the other hand, when it is set to enter the S3 (STR) state, only the supply of some power to the motherboard is stopped. For example, the power supply to the motherboard will be turned off, leaving only the power for a portion of the system chipset, including the main memory consisting of D-RAM and a memory controller for performing a refresh operation on the D-RAM.

According to the present invention as described above, in the PC integrated TV enables integrated power management between the PC unit and the TV unit by pressing the integrated body power button or remote control power button of the PC integrated TV.

When the integrated power management method is applied, not only the power control of the PC unit and the TV unit can be easily operated, but also the power saving mode reduces the boot time of the operating system of the PC unit, thereby reducing the operating time between the TV unit and the start point of the PC unit. This has the advantage of reducing the time interval as much as possible.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
