[0001]
BACKGROUND OF THE INVENTION
The present invention is a technique that can be used for a personal computer having an application (function) that can be established without using a display device represented by a music CD playback function or the like.
[0002]
[Prior art]
In recent years, integrated devices (information home appliances) of information devices typified by personal computers and audio devices typified by TVs and CD players have been commercialized by various companies.
In general, an information device refers to a user's standard input device (input device such as a keyboard / mouse) and an information processing result for a purpose of information processing such as data processing and calculation, and a standard output device (CRT / LCD or the like). The minimum control of output to the display device) is implemented.
That is, this means that when an operation / input is performed on the input device, some information is output to the display device.
[0003]
In information equipment, taking the above control in reverse, since long ago, “when the user's non-operation state (idle state) for the standard input device continues for a certain period of time, the power supply of the output device (mainly the standard output device) is cut off. Power saving control such as “Yes” is implemented.
[0004]
Furthermore, in recent years, in a personal computer having an AV function, a controller (referred to as “firmware”) that directly controls a device that is not in the form of personal computer application software, that is, without using an OS (operating system) such as Windows. Therefore, some of them support a mode for operating the AV function.
There are various types of products (systems). For example, a system configuration of a personal computer having a music CD player function can be mentioned.
[0005]
FIG. 11 shows an external view of an example of a personal computer having a music CD player function, and FIG. 12 is a block diagram showing a part of the internal configuration.
As shown in the figure, an input unit dedicated to the music CD player function for performing a music selection operation and the like, and a display unit for displaying the current song number and the like are provided separately from the standard input / output device, and further, Devices and controllers necessary to operate the CD player functions such as the drive and the input / output unit for the CD player function are always supplied with power, and only when the main power is turned on, other PC devices (standard input) The system configuration supplies power to output devices and the like.
[0006]
To be precise, when the PC is operating (when the main power switch is turned on), devices such as a CD drive and a speaker need to be operated as one of the “other devices”. Control "(cooperation control between the player control unit and the PC control unit) is required, but is omitted here.
[0007]
[Problems to be solved by the invention]
As described above, power saving (hereinafter referred to as “standby”) control as an information device, “when the user's non-operation state (idle state) with respect to the standard input device continues for a certain period of time, the output device (mainly the standard device) The control of “shutting off the power supply of the output device)” is a configuration in which “a control to output some information to the display device is necessary when an operation / input to the input device is performed” is reversed. It is.
[0008]
However, there is a case where output control for the display device is not necessarily required as a home appliance (audio device).
The most obvious one is a music playback function (CD player function).
Operations such as “start playback” and “music selection” of the CD player function, for example, the “next song selection” function at the right cursor (→) of the standard input device (keyboard), and the “previous song selection” function at the left cursor (←). Consider a scene in which the assigned PC application software is running.
[0009]
Naturally, when the above power saving control function (the power-off of the display device by continuing for a certain period of time in the idle state) is set to “valid”, if the music CD is listened for a while, this power saving function works and the main display The power supply of the device (standard display device) is controlled to be off (transition to the standby state).
[0010]
However, when a key (right cursor / left cursor) assigned to the CD player function of the standard input device (keyboard) is input for the purpose of skipping the currently playing song in this standby state, As a matter of course, when an input occurs, power supply is resumed (returns to the normal state) to the main display device (standard display device), and the content before power is shut down (CD player application window) is displayed. become.
Perhaps the above control (resumption of power supply to the standard display device) is not an operation desired by the user if the act of “listening to music” is continued.
[0011]
The present invention has been made to solve such a problem. For user operations on an input device that does not operate return control, drive control according to user operations is performed while the standby state of the display device is maintained. The purpose is to do.
[0012]
More specifically, in the “return control from the standby state by the user operation of the input device” used as one control method of the “return control from the standby state of the display device” in the power saving control for the display device, Power saving for the display device was maintained by controlling the user's operation to the input device that activates the return control and output control commands to the output device without operating the return control (while maintaining the power saving state). The purpose is to enable user operations on the output device.
[0013]
Further, the return control is activated in the “return control by user operation of the input device” in the temporary display data change control having the display device protection control which is performed when the user input is not performed for a certain period of time. Power saving for the display device was maintained by controlling the output of the control command to the output system device without operating the user operation on the input device and the return control (while maintaining the temporary display data change state). The user operation on the output device is made possible.
[0014]
Furthermore, if the user operation of the output device that is output to the output device is a command that means stop control of the output device, the power saving state for the display device or the temporary display data change state is released. It is to be.
Furthermore, the coordinate position when the mouse pad is touched (touched) is used to determine a command to be output to the output device.
[0015]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides: An information processing apparatus comprising a display device, an input means device for inputting characters and commands, and an output device for reproducing and outputting voice information, and displaying the display device by stopping power supply to at least a part of the display device Display control means having control for stopping and control for activating the display of the display means by return of power supply to the display device, and when there is no input from the input device for a predetermined time or more, the display control means Standby control means for controlling to stop the display, and when the display of the display control means is stopped by the standby control means, when the input from the input device is detected, the display control means is displayed. And a return control means for activating the input device, the input device having a sorting means having three key groups for outputting three types of commands, and a first key. The group is a key group that performs reproduction control of voice information, the second key group is a key group that controls output of voice information to be stopped, and the third key group is a key group that is not assigned to control of voice information. Yes, when the first key group is input, the display device is not controlled, and only the reproduction of the audio information is performed. When the second key group is input, the reproduction of the audio information is stopped, The display device is activated by the return control means, and when the third key group is input, the display device is activated by the return control means. It is characterized by that.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a drive control method in a standby state according to the present invention will be described below with reference to the drawings.
FIG. 1 is an external view and a partially enlarged view of a PC with a music CD player function to which the drive control method in the standby state of the present invention is applied.
[0017]
On the mouse pad of the PC system, icons representing the music CD player function playback control functions (four functions of “play”, “stop”, “next song skip”, and “pause”) are printed (engraved). When the area where these icons are engraved is touched when the display device is in the power saving state, the power saving state is maintained (exactly, only “stop” is controlled to return from the power saving state). When an individual reproduction control function is activated and an area where no icon is stamped is touched, the power saving state is restored.
[0018]
Similarly to the mouse pad, the playback control function of the music CD player function is also assigned to the “A” key, “S” key, “Z” key, and “X” key on the keyboard. If any of the above four keys is pressed while the display device is in the power saving state, the power saving state is maintained (return control is performed in the same manner as the pad for “stop”), and individual playback is performed. When the control function is activated and any other key is pressed, it returns from the power saving state.
[0019]
FIG. 2 is a block diagram showing the configuration of a PC with a music CD player function that implements the PC system shown in FIG.
Below, each component is explained in full detail.
The arrows between the blocks indicate the input / output relationship of basic data (the blocks whose arrows are controlled / output).
[0020]
First, the input device controller 20 comprehensively manages user input data output from the keyboard 35 and the mouse pad 30, controls output of input data to the system 10 described later, and a music CD playback controller 40 also described later. In contrast, the control unit outputs a reproduction control command (command).
However, here, in order to simplify the description, the keyboard 35 and the mouse pad 30 are collectively handled and are different from the system 10, but the actual form may be incorporated in the system 10 ( Generally, it is called “driver software” in a sense that distinguishes it from the latter.) Or exists as a separate (ROM) form (generally called “BIOS” to distinguish it from the former). Part of the system code.
[0021]
Next, the system 10 is a control unit that inputs operation data for a user input device output from the input device controller 20 and performs idle detection control and power saving control of the display device 60 associated with the idle detection control.
However, as in the case of the input device controller 20, here, for simplicity of explanation, the power saving control is limited to the display device 60. Naturally, however, a device (backlight / light source) that assists in improving the visibility of the display device. Power saving for front lights, etc. is also included, and “system” as a general PC term (usually simply “system” is basically the OS in terms of PC, broadly BIOS, driver software, etc. In other words, the power-saving control for the display device is only a part of the control. For example, various controls are performed even if one power-saving control is taken. ing.
[0022]
In addition, the music CD playback controller 40 is controlled by the input device controller 20, a drive (CD reading device 55) for a medium (CD: Compact Disc in this embodiment) in which music digital content is stored, and an amplifier / A control unit (controller) in firmware that controls the audio output device 50 such as a speaker and reproduces the audio.
[0023]
In general, when a PC (under OS management) application software (not shown) controls various devices, it is always controlled via the OS (system 10 in FIG. 2).
That is, music CD player application software in the form of PC application software means that the music CD playback controller 40 may be controlled via the system 10.
[0024]
Next, the output format of input data will be described.
FIG. 3 is a diagram showing an example of the playback control function area of the music CD player assigned on the mouse pad.
What should be noted here is that not all areas on the pad are assigned to the playback control function of the music CD player. This indicates that when the area not assigned to the playback control function of the music CD player is operated (touched) in the power saving state, the return control is performed from the power saving state.
[0025]
FIG. 4 is a diagram illustrating an example of interface specifications (input / output data format) between the mouse pad and the input device controller and between the input device controller and the system regarding the mouse pad operation of the present embodiment.
FIG. 4A shows a data format output from the mouse pad 30 (the input side is the input device controller 20).
[0026]
As can be seen from this figure, it is composed of 4 parameters (in the case of pad operation) / 3 parameters (in the case of button operation).
The first parameter means a data type of input (operation) data, and PAD is output in the case of pad operation, and BTN is output in the case of button operation.
The second and subsequent parameters mean input contents of input (operation) data. In the case of pad operation, the currently touched horizontal (Px) position, vertical (Py) position, current touch state information ( UpDown) is assigned to the first parameter and output.
[0027]
In the case of a button operation, the operated button number (BNo) and the button pressing state information (UpDown) are also given to the first parameter and output.
This specification is merely an example, and need not be the same as this specification. However, at least in the case of pad operation, the input device controller 20 is controlled by receiving the output of the physical position on the pad (control). For details, see the flow description below.)
[0028]
FIG. 4B shows a data format output from the input device controller 20 (system 10 on the input side).
As can be seen from this figure, it consists of four parameters: a horizontal direction (MvX) movement amount, a vertical direction (MvY) movement amount, a left button (LBs) pressed state, and a right button (RBs) pressed state.
Similar to FIG. 4A, this specification is merely an example, and need not be the same as this specification. However, unlike FIG. 4A, the movement amount (relative position) of the pad is output. The point should be noted.
That is, the input device controller 20 converts the physical operation location in the pad output from the mouse pad 30 into a movement amount (relative position) and outputs it to the system 10.
[0029]
In general, the input data of the keyboard also includes a data format output from the keyboard 35 (usually, at least two parameters indicating the operated key number and the UpDown state of the key). ) Is different from the data format output from the input device controller 20 (generally converted to a character code). However, in this embodiment, all (including the output of the keyboard 35) is simple. It is assumed that the character code is output.
[0030]
Next, the contents of the resume suppression table 21 will be described.
FIG. 5 is a diagram illustrating an example of the contents of the resume suppression table 21.
FIG. 5A shows the setting values of the resume suppression table for keyboard input, and FIG. 5B shows the resume suppression table for mouse pad input.
[0031]
In this embodiment, these table values are fixed to the system, but may be set / changed by the user.
In both tables, a drive control command (CCmd) and a condition value (FIG. 5 (A) is a key code and FIG. 5 (B) is a pad area) for outputting this drive control command to the music CD playback controller 40. Are stored in association with each other.
[0032]
In other words, the resume suppression table 21 corresponds to when the input device controller 20 checks whether there is output of input data that matches the condition value during the power saving mode and determines that there is an output. A table for outputting a drive control command to the music CD playback controller 40 is not limited to the present embodiment as long as the above-described control is possible.
[0033]
Further, as can be seen from FIG. 5, the music CD playback controller 40 has four functions of Play (1), Stop (2), Skip (3) and Pause (4). It may be more or less, and the interface specification is not limited to this specification.
[0034]
Finally, details of individual control contents and a processing flow of the system 10 and the input device controller 20 will be described.
FIG. 6 is a flowchart showing the processing procedure of the system 10.
First, the detailed control of the system 10 that controls the power saving control for the display device 60 will be described with reference to FIG.
[0035]
In this control unit, first, the timing device 70 and the idle counter 16 are initialized (step S601).
Note that the time measuring device 70 here is an image of a signal output to the system 10 at a constant cycle, and the initialization of the time measuring device is a signal for resetting the cycle (in the time measuring device, the reset is This means that the timekeeping control is started after receiving the signal, and a signal is output to the system 10 in a specified cycle unit).
[0036]
Further, the idle count 16 receives a periodic signal from the timing device 70, is always incremented, and receives an output from the input device controller 20 to the input device (an output related to the input operation of the keyboard 35 and mouse pad 30). A reset (0 value substitution) process is performed, that is, the idle counter 16 stores the time from the last input (period unit of the time measuring device 70).
[0037]
Further, the PM operation set value 15 is a system constant (although there is no problem even if it can be changed by the user, in this embodiment, it will be described by limiting to a system fixed value). When it coincides with the PM operation set value 15, it is for determination to start power saving control for the display device 60.
Following step S601 (initialization) processing, it is checked whether or not there is a signal output from the timing device 70, that is, whether or not a certain time has passed (step S602).
If there is no output from the timing device 70, it is further checked whether there is an output from the input device controller 20 (user input operation) (step S603).
[0038]
Here, if there is no output from the input device controller 20, the process returns to step S 602 and is repeatedly controlled from the signal output check from the time measuring device 70.
On the other hand, if there is an output from the input device controller 20, after the time measuring device 70 and the idle counter 16 are initialized (step S604) as in step S601, the current power saving mode is in the standby state, that is, the display. Only when the power is not supplied to the device 60 (step S605), the power supply circuit 65 is turned on, that is, the power supply to the display device 60 is started (step S606), and the standby state is entered. The internal RAM of the display device 60 at the time (generally, the volatile memory in the controller in which the controller state and the like are stored is referred to as “register”, and “internal RAM” refers to this, VRAM, that is, a volatile memory in which display data is stored). Restore the save data saved in the data saving storage 17 (output to the display device 60) (step S607), further, that it has returned from the standby state, and outputs it to the input device controller 20 (step S608).
[0039]
Note that the output (user input operation) data from the input device controller 20 in step S603 is not simply used for returning from the standby state, but application software (illustrated) that is a higher-level block of the system 10. (If it is a system that can run multiple application software, it is output to the active application), or if the system 10 itself has a role of controlling user input operations In the system 10, control is performed on this input data (step S609). Since this is not directly related to the present invention, details are omitted.
[0040]
If the control (steps S604 to S609) for the output from the input device controller 20 is completed, the process returns to step S602 again.
In step S602, when there is a signal output from the time measuring device 70 (a certain time has elapsed), the power saving mode is in the standby state, that is, power is supplied to the display device 60. It is checked whether or not there is no state (step S610). If it is already in the standby state, the process returns to step S602.
[0041]
If it is not yet in the standby state, the idle counter 16 is incremented (step S611), the idle counter 16 at this time is compared with the PM operation set value 15, and the idle (uninput) state continues for a certain period. It is checked whether or not it has been performed (step S612), and when it is determined that the idle state has been maintained for a certain period, the RAM contents of the display device 60 are saved in the display device RAM data saving storage area 17 (step S613). Then, the power supply circuit 65 is turned off, that is, the power supply to the display device 60 is cut off (step S614), and further the fact that it has shifted to the standby state is output to the input device controller 20 (step S615).
Of course, if the control (steps S613 to S615) is completed, the process returns to step S602 again.
[0042]
Next, an input device that receives output from the keyboard 35 or the mouse pad 30 and controls whether or not to continue the power saving mode (perform music CD playback control) when the display device 60 is in the power saving mode. Detailed control of the controller 20 will be described.
FIG. 7 is a flowchart showing the initial entry process of the input device controller 20.
[0043]
First, the initialization of the local variable PMFlag indicating whether or not it is in the power saving mode (step S701) and the input data from the mouse pad 30 are converted into the output data for the system 10 (in short, the physical position data described above). Initialization of local variables Mx, My, and Mf for converting the input / output data format shown in FIG. 4A to the input / output data format shown in FIG. 4B that is relative position data (step) S702) is performed.
[0044]
After the initialization control (steps S701 and S702), the variable PMFflag setting control (steps S703 to S706) by checking the output of whether or not a change in the power saving mode has occurred from the system 10, and the mouse pad 30, or the transition control (steps S707 and S708) to each entry (step 10707, entry 708 for the input of the mouse pad 30 and entry 20 for the input of the keyboard 35) by checking the output in response to the user input operation from the keyboard 35 is repeated. (Loop entry 0) is performed.
[0045]
FIG. 8 is a flowchart showing the control contents when an output corresponding to the user's input operation is generated from the mouse pad 30 in step S707 of FIG. First, the current power saving mode is checked (step S801), and if it is in a standby state, the process proceeds to entry 15 to be described later.
[0046]
When the current power saving mode is not in the standby state, the output data (input / output data format shown in FIG. 4A, that is, physical position data) for the user input operation from the mouse pad 30 is stored in the system 10. Is converted into a data format (input / output data format shown in FIG. 4B, that is, relative position data) and output to the system 10 (steps S802 to S812).
[0047]
The detailed logic of the conversion control is as follows: the local variables Mx and My are the touch physical position immediately before (one before) on the pad, and the local variable Mf is the user's from the previous (one previous) mouse pad 30. It means whether or not the output in response to the input operation is caused by releasing the hand from the pad (0 value) (1 value).
[0048]
First, when the output for the user input operation from the mouse pad 30 this time is a mouse pad button (BTN), the parameters MvX and MvY to the system 10 are set regardless of the local variables Mx, My and Mf values. Set the value (LBs / RBs) of the button on the operated side of the left and right buttons (LBs / RBs) on the operation side (the operation side substitutes the parameter UpDown value, the other substitutes the 0 value), The data is output to the system 10 (step S803).
[0049]
If the current output from the mouse pad 30 to the user input operation is mouse pad operation (PAD), the local variable Mf value is further checked (step S804), and the previous touch state is on the pad. If it is not in the touch state (not in the touch state), it is checked whether the output corresponding to the user's input operation from the current mouse pad 30 has transitioned to the touch state (parameter UpDown value). In the case of transition to the touch state without any control, the parameters MvX and MvY to the system 10 are set to 0 values (not moved), and the left button is further pressed (LBs to DN value, RBs as 0), output to the system 10 (step S803), and the mouse pad related variables are displayed in this mouse pad. Output value for the input operation of the user from the 30 (Mx is Px, My is Py, Mf 1 value) is updated (step S807).
[0050]
Further, when the previous touch state is on the pad (in the touch state), it is checked whether or not the current output from the mouse pad 30 in response to the user's input operation is the continuation of the touch state (parameter UpDown value). (Step S808) When the touch state is lost (the hand is released from the pad), the parameters MvX and MvY to the system 10 are set to 0 (not moving), and the left button is released. (LBs is UP value, RBs is 0 value) and output to the system 10 (step S806). Conversely, when the touch state is continued (finger movement on the pad), the parameters MvX and MvY to the system 10 are The difference values (movement amounts) between the local variables Mx, My and the parameters Px, Py output values for the user input operation from the mouse pad 30 this time Meter LBs, RBs as 0 values (no state transition) to the system 10 (step S811).
[0051]
Naturally, after both output to the user's input operation to the system 10, both of the mouse pad related variables Mx, My, Mf are values corresponding to the output values for the user's input operation from the mouse pad 30 (Step S810 side is on the pad). Since the hand has been released, all variables are initialized, that is, 0 value, because the variable Mf is in the state continuation on the step S812 side, the value is not changed, and the variables Mx and My are new ) (Step S810, step S812), the process proceeds to loop entry 0.
[0052]
FIG. 9 is a flowchart showing the control contents when an output in response to a user input operation from the mouse pad 30 in the standby state occurs in step S801 in FIG.
That is, the control content shown in FIG. 9 is the most important (point) part of the present invention.
Prior to the description of the control contents, “execute the step of outputting input data to the system 10” means “return control from the standby state (by steps S606 to S608 in the control of the system 10). It is first noted that this is the case.
[0053]
First, it is checked whether or not the output for the user input operation from the mouse pad 30 is a mouse pad button (BTN) (step S901). Parameters MvX and MvY to the system 10 are set to 0 (no movement), and the parameter (LBs / RBs) of the operated button among the left and right buttons is set (the operation side substitutes the parameter UpDown value, the other (0 is substituted) and output to the system 10 (step S902). That is, the operation of the mouse pad button is controlled to return from the standby state, that is, the same operation as the current state (conventional).
[0054]
Next, when the output corresponding to the user input operation from the mouse pad 30 is a mouse pad operation (PAD), first, the previous touch state is on the pad with the local variable Mf value (touch state). It is checked whether or not (step S903).
If the previous state is a touch state, the updated value is the same as the output value for the user's input operation from the current mouse pad 30 (the updated value is the same as when not in the standby state), but it is simply related to the mouse pad. Only the variables are updated (steps S904 to S906), and no input data is output to the system 10.
[0055]
The control for suppressing the output to the system 10 is performed immediately after touching a specified area on the pad (of course, an area allocated for command output to some audio CD playback controller 40) from the pad. Meaningless input data until the finger is released (the standby state continues during this time) (It is related to the input accuracy of the pad, but it is most likely to occur when the finger is released. This means that the recovery from the standby state due to input data that does not make sense by the
[0056]
If the previous state is not the touch state, it is checked whether or not the current output from the mouse pad 30 for the user input operation means a transition to the touch state (step S907), and the touch state is entered. In the case of the transition, the mouse pad related variable is updated (step S908).
If the touch state has not been changed (which is impossible), the input is ignored.
[0057]
Further, whether the touch position is assigned to the playback control function of the music CD player function based on the physical position (parameter Px, Py value) on the pad, which is an output parameter for the user's input operation from the mouse pad 30 this time. Whether or not is determined is determined by the resume suppression table 21 shown in FIG. 5B (steps S909 to S903).
[0058]
In this embodiment, the playback control function of the music CD player function is limited to four functions of “play”, “stop”, “skip next song”, and “pause”. It is carried out.
Specifically, first, the local variable i is initialized (0 value substitution) (step S909), and the i physical value (Px, Py) is the i-th value between 0 and 3 (4 loops). It is checked whether or not it exists in the area (CArea) of the resume suppression table for mouse pad (step S910). If it is not in the area, the i value is incremented and loop processing (up to i = 3) is performed. If i becomes larger than 3 (when the check for 4 functions is completed: step S912), the parameters MvX and MvY to the system 10 are set to 0 (not moved), and the left button is further pressed (LBs (DN value and RBs as 0 value) and output to the system 10 (step S913).
[0059]
If the area check in step S910 determines that the area is within the area (CArea), a reproduction control command corresponding to the CD reproduction controller 40 is output (step S914).
Only when the corresponding playback control command function is “stop” (step S915), the system 10 outputs the same output as when it was not in the area (step S913).
That is, by the above control, if the touch is at the pad position corresponding to the playback control function, the playback control function is output to the CD playback controller 40, the touch at the pad position not corresponding to the playback control function, and the “stop” function In the case of a touch at a pad position corresponding to, input data is output to the system 10 so that the return control from the standby state works.
[0060]
The control flow for the mouse pad 30 has been described above. Next, a control flow in which the same control is performed on the keyboard 35 will be described.
FIG. 10 is a flowchart showing the control contents when an output corresponding to a user input operation is generated from the keyboard 35 in step S708 in FIG.
First, the current power saving mode is checked (step S1001), and if not in the standby state, the output data from the keyboard 35 is output to the system 10 as it is.
[0061]
If it is not in the standby state, whether the output data (key data) corresponding to the user's input operation from the keyboard 35 is data assigned to the playback control function of the music CD player function or not is shown in FIG. Judgment is made using the suppression table 21 (steps S1003 to S1007).
In this embodiment, the playback control function of the music CD player function is limited to four functions of “play”, “stop”, “skip next song”, and “pause”. It is carried out.
[0062]
Specifically, first, the local variable i is initialized (0 value substitution) (step S1003), and the key data output from the keyboard 35 is the i-th keyboard while the i value is 0-3 (4 loops). It is checked whether or not it matches the key data (CKkey) of the resume suppression table for use (step S1004). If it does not match, the i value is incremented and loop processing (up to i = 3), and the loop counter i is 3 When it becomes larger (when the check for four functions is completed: step S1006), output data from the keyboard 35 to the system 10 is output (step S1007).
[0063]
If the key data check in step S1004 matches, a playback control command corresponding to the CD playback controller 40 is output (step S1008).
Only when the corresponding playback control command function is “stop” (step S1009), the same output as when the key data does not match is performed to the system 10 (step S1007).
[0064]
That is, if the key data corresponding to the playback control function is output by the above control, the playback control command corresponding to the key data is output to the CD playback controller 40, the key data not corresponding to the playback control function, and “stop”. In the case of key data corresponding to a function, input data is output to the system 10 so that return control from the standby state works.

【The invention's effect】
According to the present invention, for a user operation on an input device that does not operate return control, drive control corresponding to the user operation is performed in a state in which the standby state of the display device is continued. It is possible to perform a power saving operation as a desired information device.
Then, the user can operate the output system device while maintaining the power saving state for the display device without separately preparing an input device dedicated to the output system device.
[0066]
Furthermore, the user can operate the output system device while maintaining the temporary display data change control for the display device without separately preparing an input device dedicated to the output system device.
[0067]
Furthermore, after outputting the stop control to the output device, it is easy (can be operated immediately) to use the information processing function or shut down the information device system body, which is likely to be operated by the user. Therefore, the power saving state for the display device or the temporary change state of the display data can be canceled.
[0068]
In addition, as an input device, it is easy to control by converting the physical coordinate position into a relative coordinate position, and adapting the relative coordinate position to the mouse pad controlled as input data. In a personal computer system in which system specifications are defined, user confusion can be prevented.
[0069]
Further, as the mouse pad input data, the command decision input data suitable for the output device can be obtained by using the position when the mouse pad is touched as the input data.
