The input detection signal DS is supplied to the data conversion unit 46 via the terminal b of the switch 48. Then, the input detection signal DS is packetized in the transmission format described later with reference to FIG. The output signal of the data conversion unit 46 is, for example, 455 KH output from the carrier oscillation unit 63.
The carrier signal of Z is modulated by the mixer 67 and supplied to the transmission unit 45 via the terminal d of the switch 66. Then, the light is transmitted from the light emitting unit 136 as infrared light. Here, the data conversion unit 46 generates the absolute position information AP in accordance with the detection signal when the mode is the absolute mode, and calculates the relative position information RP when the mode is the relative mode.
Will be output.

When the command mode is selected, the input detection signal DS is supplied to the command converter 43 via the terminal a of the switch 48. Then, the command conversion unit 43 packetizes the input detection signal DS in a transmission format described later with reference to FIG. 19 and supplies it to the mixer 68 via the adder 69 as command information IC. In the mixer 68, the tablet input information IT is modulated by a carrier signal of, for example, 38 KHz output from the carrier signal 64, and is transmitted through the terminal d of the switch 66 to the transmitting section 4.
5 is supplied. Then, the transmitting unit 45 drives the light emitting unit 45 based on the input signal. Thereby, the light emitting unit 3
From 6, infrared light is transmitted based on the command information IC.

When the key input signal IK of various operation keys supplied from the operation key unit 47 is supplied, the control unit 44
The command code corresponding to the key input signal IK is stored in the ROM
Read from 61. Then, the read command code is supplied to the mixer 68 via the adder 69. As a result, the command code is modulated by a carrier signal of, for example, 38 KHz output from the carrier oscillating unit 64, supplied to the transmitting unit 45 via the terminal d of the switch 66, and transmitted from the light emitting unit 136. The transmission processing in the tablet mode and the command mode is executed by detecting the input detection signal DS supplied from the input information detection unit 42. Further, in response to the operation of the tablet mode switching key 125 provided on the operation key section 47, a light emitting diode (LED) is provided.
e)) Turn on and off 71.

The transmitting section 45 causes the light emitting section 136 to emit light in accordance with the signal selected by the switch 66, and transmits the light to the set top box 1 or the monitor device 11. The transmission signal transmitted from the light emitting unit 136 is received by the light receiving unit 10 and the light receiving unit 12 of the monitor device 11 and then demodulated to perform various controls. That is, for example, when the relative position information RP or the absolute position information AP is transmitted in the tablet mode, the set-top box 1 controls to move the pointer according to the position information. For example, in the command mode, for example, the channel selection mark 12
When an input is made in the area No. 2, control for selecting a broadcast channel is performed. This is because the type of a transmission signal (command or position information) transmitted from the remote control device 114 is identified by a command identification code of a transmission format described below, and various types of control are performed by the set-top box 1 or the monitor device 11. This is because it is performed.

The reason why two types of carriers are used is to use 38 KHz, which is the carrier frequency of the ordinary remote control device 114, when only the command transmission is considered. When performing the pointing operation, a carrier frequency of 455 KHz is used because the operation accuracy of the pointer is required. Therefore, for example, the light receiving unit 10 of the set-top box 1 is configured to correspond to a carrier frequency of, for example, 455 KHz, and for example, the monitoring device 11
The light receiving unit 12 is configured to support a carrier frequency of 38 KHz, for example. Thus, for example, the demodulation system of command data such as channel selection and volume adjustment in the monitor device 11 can be used with the conventional configuration.

In the example described with reference to FIG. 17, the position information is modulated at a carrier frequency of, for example, 455 KHz, and the command information IC is modulated at a carrier frequency of, for example, 38 KHz.
It is also possible to transmit by modulating with the carrier frequency of HZ. Thus, the receiving side only needs to have a demodulation system of a carrier frequency of 455 KHz, which is advantageous in that the configuration can be simplified.

(7) Description of Transmission Format of Remote Control Device of the Present Invention Next, referring to FIGS. 18 and 19, for example, 455K transmitted by the remote control device 114 of the present invention.
The format of a packet transmitted at the carrier frequency of HZ will be described.

That is, the command signal of this embodiment is transmitted such that the unit of a fixed-length data group called a packet is continuous. FIG. 18A shows the data structure of one packet. As shown in FIG. 18A, one packet is made up of 64 bits, and includes a manufacturer identification code area A1, a remote control identification code area A2, the same remote control identification code area A3, a data identification code area A4,
It consists of a data area A5 and a parity area A6.

The maker identification code area A1 (12 bits) is an area in which a code for identifying the maker of the remote control device 14 is set. Subsequently, the same commander identification code area A2 (4 bits) is an area of a code for identifying the type of the remote control device 14 in the same manufacturer, and the same remote control identification code area A3 (4 bits) is used for the same type of remote control. The data identification code area A4 (4 bits) is a code area for identifying the type of data in the data area. That is, in the present embodiment, the data identification code area A4 is a key / tablet input signal by a key input or an input of the tablet 20 in the command mode, a detection signal of the tablet 20 in the tablet mode, an absolute coordinate data in the tablet mode or This is a data area in which a flag or the like for identifying whether the data is relative coordinate data is set. To each of these areas (A1 to A4), a code set according to the manufacturer and type of the remote control device 114 actually used, the type of data based on the transmission format, and the like is given. Note that these code data are also stored in the command table 43 or the ROM 61 in advance.

The data area A5 (32 bits) is an area to which command information IC indicating the input operation key or click key 32 or position information RP / AP is allocated. In this embodiment, position information (absolute position information RP or relative position information AP) is written when the tablet mode is selected. As described above, for example, the key input signal IK of the operation key unit 47 or the command information IC (for example, volume control, channel selection, etc.) when the command mode is selected may be assigned.
The last error detection area A6 (8 bits) is a parity bit area for error detection.

FIG. 18B is a view for explaining a format example of the data area A5. The click key data area A5-a (4 bits) is an area for identification data indicating whether or not the click key 32 has been input, and a flag for validity of the identification data. For example, the first bit is an area indicating an input of the click key 32 (or 32a), and the third bit is a cancel key 29 or a cancel key 32b.
This area indicates the input of "1".
It's been shaky. That is, in the present embodiment, when the set-top box 1 on the receiving side determines that the first bit of the click key data area A5-a is “1”, it is determined that the input of the click key 32 has been performed, Thereafter, a command corresponding to the input coordinate data is executed.

The second bit can be used for a click key 32, a cancel key 29, and other keys provided with a key for performing an input by a click operation. The fourth bit is a valid / invalid area of a validity flag indicating the validity of the data, and is set to "1" when valid and "0" when invalid.

The X-coordinate area A5-b (10 bits) and the Y-coordinate area A5-c (10 bits) are used as absolute coordinate data or relative coordinate data detected by the position information detecting section 42 by the input of the tablet 20, respectively. X coordinate data and Y coordinate data are written and transmitted. That is, the X coordinate area A5-b and the Y coordinate area A5-c
By decoding the coordinate data on the set top box 1 side, it is possible to perform control to move or display the pointer to a position corresponding to the coordinates input by the tablet 20. Data area A
In the case where the key input signal IK or the tablet input signal IT is written in 5, the control according to the command is executed in the set-top box 1 or the monitor device 11.

The format of the packet transmitted by the remote control device 114 at a carrier frequency of, for example, 38 KHz is as shown in FIG. 19, for example. The model category area B1 includes, for example, the set-top box 1, the monitor device 11, and the VT.
R (Video Tape Recorder) or the like is a region in which a code for identifying an electronic device to be controlled is set, and a data area B2 is used for various types of channel setting, volume adjustment or reproduction, recording, etc. set for each electronic device. It is an area to which a command code is assigned. So, for example,
When adjusting the volume of the monitor device 11, a code indicating the monitor device 11 is written in the model category area B1, and command information IC relating to the volume adjustment is written in the data area B2.

The format shown in FIG. 19 is an example, and the actual format only needs to include at least the illustrated model category area B1 and data area B2, and other data items may be added as necessary. The format may be configured by using

(8) Outline of remote control operation of monitor device by remote control device of the present invention Next, referring to FIGS. 20 to 25, remote control operation of monitor device 11 by remote control device 114 of the present invention will be described. Will be described.

First, FIGS. 20 (a) to 20 (d) and FIG.
(A)-(c) is a figure which shows an example of the display form of CRT13 of the monitor apparatus 11 when performing various operation with the tablet 120 of the remote control apparatus 114,
FIGS. 20A to 20D show CRs in the command mode.
The screen display of T13, FIGS. 21A to 21C show the tablet 20 in the tablet mode (absolute mode, relative mode).
And the state of movement of the pointer displayed on the CRT 13.

In the case where the command mode is selected by operating the tablet function switching key 25, for example, when the area of the volume adjustment mark 21 described above with reference to FIGS. 1 to 8 is operated, for example, FIGS. The volume can be adjusted as shown in (b). Similarly, when the area of the channel selection mark 23 is operated,
For example, as shown in FIG. 20 (c) to FIG. 20 (d), the selected broadcast channel can be switched from “5 channel” to “7 channel”, for example.

When the tablet mode is selected by operating the tablet function switching key 125,
When the GUI menu key 130 is operated, a menu screen is generated in the video amplifier 5 of the set-top box 1 and displayed on the CRT 13. However, in this case, it is assumed that the input channel of the monitor device 11 is switched to the set-top box 1 and the reproduction data such as music and movie supplied from the set-top box 1 is being viewed.

As shown in FIG. 21A, for example, the menu screen includes various operation items such as reproduction, pause,
For example, an arrow-shaped pointer 82 is displayed together with an icon area 81 including an icon such as a stop icon. The pointer 82 is touching the tablet 20, for example a thumb F _1, it is possible to move the display position on the screen indicated by broken line arrows in accordance with the direction and distance mentioned. The amount of movement of the pointer 82 in the relative mode
Corresponds to the amount of movement of the thumb F ₁ on. Then, as shown in FIG. 21B, for example, when the pointer 82 is moved to a display area in which an icon indicating reproduction is displayed and the decision click key 132 is operated, control for reproducing data is performed. . Thereby, the recording medium driving device 2 reads out desired data from the recording medium.

In FIGS. 21 (a) and 21 (b), G
Although an example is shown in which the video being viewed is switched to the GUI menu screen by operating the UI menu key 130, the video will not be completely displayed in this case, as shown in FIG. 21 (c). Menu screen 8
3 may be superimposed and displayed. Thus, for example, when watching a movie or the like, the video and the menu screen 83 can be displayed simultaneously.

FIG. 22 shows a remote control device 114.
FIG. 4 is a diagram showing an example of a display form on a CRT 13 of a monitor device 11 when various operations are performed by a tablet 20 of FIG. When the tablet mode is selected by operating the tablet function switching key 125, when the GUI menu key 30 is operated, for example, FIG.
(B), a menu screen is generated as shown in FIG. 22 (c) and displayed on the CRT 13 of the monitor device 11. On this menu screen, a pointer 82 is displayed together with an icon group I composed of various operation items (play, pause, stop, etc.). However, in this case, the input channel of the monitor device 11 is switched to the set-top box 1 in advance, and reproduction data (for example, supplied from computer communication or disk media) of, for example, a movie or music supplied from the set-top box 1 is supplied. You are watching. 22D, FIG. 22E, FIG.
(F) shows the input state of the tablet 20 corresponding to FIGS. 22 (a), 22 (b) and 22 (c).

In the relative mode, for example, FIG.
As shown in FIG. 22, when the pointer 82 is displayed at the upper left of the CRT 13, the state shown in FIG. 22D is changed from the state shown in FIG. 22D to the state shown in FIG.
Moving the thumb F ₁ from the upper left side to the central portion in a state of touching the tablet 120, in the direction indicated by broken line arrows in FIG. 21 (a), the pointer 82 moves along with the movement of the thumb F _1, FIG. 21 As shown in (b), it moves to the central part of the CRT 13. Furthermore, for example, FIGS.
When 2 thumb F ₁ in the direction indicated by the solid line arrow as (f) is moved to the lower right of the tablet 120, the pointer 82 in the direction indicated by the broken line in FIG. 22 (b) also in accordance with the movement of the thumb F ₁ CRT 13 To the lower right of FIG. 22 to become as shown in FIG.

Further, by transmitting absolute position information in response to the input of the tablet 120 in the tablet mode, it is possible to directly point a desired icon on the menu screen. Then, as this direct other tablet mode the mode for performing pointing and selecting the tablet function switching key 125, it is possible to select a desired icon without moving the thumb F ₁ in tablet 120 on . In this case, by operating the tablet function switching key 125, mode switching may be performed in the order of, for example, the command mode, the absolute mode, and the relative mode.

By transmitting the absolute position information, it is possible to directly point by touching the area of the tablet 120 corresponding to the position where the desired icon is displayed on the menu screen. That is, FIG. 22 (d), FIG. 22 (e), FIG.
(F) rather than moving the thumb F ₁ as shown, the tablet 12 shown in example FIG. 22 (d)
When the user touches the area 0, the pointer 82 is displayed at the position shown in FIG. 22A, and when the user touches the position shown in FIG. 22E, the pointer 82 is displayed at the position shown in FIG. Will be. That is, the display area of the CRT 13 and the input area of the tablet 120 are associated with each other on a one-to-one basis, and the pointer 82 can be moved with absolute position information.

Therefore, even when a menu screen as shown in the figure is displayed on the monitor device 11 composed of a large display unit and the pointer 82 is moved, a large operation or a repetitive operation is not required, and a desired icon or the like can be obtained. Pointing can be performed easily. Then, by moving the pointer 82 to a desired icon and operating the determination click key 132, a command corresponding to the icon is executed.

FIG. 23 shows the remote control device 11.
9 is a flowchart illustrating a process that is repeatedly performed in a control unit 44 of FIG. First, when any operation is performed on the remote control device 114, the control unit 44 detects whether the operation is on the tablet function switching key 125 (S001). When the control unit 44 detects that the operation is for the tablet function switching key 125, the control unit 44 switches the mode and stores the mode after the switching. That is, the control unit 44 controls the switches 48 and 66 to switch the connection between the switches 48 and 66. Specifically, when switching to the command mode, the control unit 44 sets the switch 48 so that the terminal a of the switch 48 and the terminal c of the switch 66 are connected.
In addition to controlling the switch 66 and storing the data indicating the command mode in the RAM 62, when switching to the tablet mode, the switch 48 is connected so that the terminal b of the switch 48 and the terminal d of the switch 66 are connected.
And switch 66, and stores data indicating the tablet mode in the RAM 62 (S00
2). The control unit 44 turns on the LED 71 when the mode is switched to the command mode, and turns off the LED 71 when the mode is switched to the tablet mode (S0).
03).

The control unit 44 determines whether or not a key switch other than the tablet function switching key 125 has been operated when it is determined in step S001 that the operation is not an operation on the tablet function switching key 125 and when the processing in step S003 is completed. It is detected (S004). When detecting that a key switch other than the tablet function switching key 125 has been operated, the control unit 44 transmits a command corresponding to the operated key switch (S005). That is, the control unit 44 reads a command corresponding to the operated key switch from the ROM 61 and supplies the command to the adder 69. Thus, a command corresponding to the key switch is transmitted from the light emitting unit 36.

The control unit 44 detects whether or not an operation has been performed on the tablet 120 when detecting in step S004 that a key switch other than the tablet function switching key 25 has not been operated and when ending the processing in step S005. (S006). This can be detected by inputting the output of the position information detection unit 42 to the control unit 44. Control unit 4
In step S007, when it is detected in step S006 that an operation has been performed on the tablet 120, transmission processing is performed according to the selected mode (S007). Specifically, the control unit 44
Causes the data conversion unit 46 to perform the data conversion processing according to the mode of the tablet function stored in the RAM 64, that is, the absolute mode or the relative mode. Thereby, the relative position information RP or the absolute position information AP obtained by converting the input position information IP into data by the data conversion section 46 is supplied to the mixer 67. Then, the relative position information RP modulated by the carrier signal by the mixer 67
Alternatively, the absolute position information AP is transmitted to the switch 66 and the transmitting unit 45.
Is transmitted from the light emitting unit 36 via the.

FIG. 24 shows step S007 of the flowchart shown in FIG. 23 in detail. The control unit 44
First, it is determined whether the input function of the tablet 120 is in the command mode or the tablet mode (S101). Here, if it is determined that the mode is the command mode, the switch 48 is switched to the terminal a side (S102), and the detection signal is supplied to the command conversion unit 43 as the command information IC. Then, the comparison circuit 43a of the command conversion unit 43 compares the input detection signal DS with each address of the command table 43b, so that the command data of the address corresponding to the input detection signal DS is read from the command table 43b. The command data read from the command table 43b is subjected to signal processing such as addition of an error correction code in the command conversion section 43c, and is supplied to the mixer 68 as command information IC. Then, the command information IC modulated by the carrier signal by the mixer 67 is transmitted from the light emitting unit 36 via the switch 66 and the transmitting unit 45.

If the control unit 44 detects in step S101 that the input function of the tablet 120 is in the tablet mode, the switch 48 is switched to the terminal b (S103), and the input detection signal DS is converted to the data conversion unit 46. To supply. Next, the control unit 44 detects whether the mode is the absolute mode or the relative mode (S104). When detecting that the absolute mode is selected, the control unit 44 instructs the data conversion unit 46 that the mode is the absolute mode (S105).
Then, the data processing section 46 performs signal processing such as adding an error correction code to the input detection signal DS,
The output of the data generator 46 is supplied to the mixer 67 as the absolute position information AP. Then, the absolute position information AP modulated by the carrier signal by the mixer 67 is transmitted from the light emitting unit 36 via the switch 66 and the transmitting unit 45.

When the control unit 44 detects in step S104 that the relative mode has been selected, it instructs the data conversion unit 46 to be in the relative mode (S106). In this case, the data conversion unit 46 calculates relative position information from the input detection signal DS and performs signal processing such as addition of an error correction code.
Is supplied to the mixer 67 as relative position information RP. The relative position information RP modulated by the carrier signal by the mixer 67 is transmitted from the light emitting unit 36 via the switch 66 and the transmitting unit 45.

As described above, the input mode of the tablet 120 is a command mode for inputting various commands,
An absolute mode, which is a tablet mode for moving a pointer displayed on the RT 13, and a relative mode are provided. Then, the user selects the absolute mode or the relative mode according to the user's preference, the configuration of the menu screen, the usability of the application software or the like, and selects the tablet 120.
By performing the input operation described above, a comfortable input operation according to the intended use can be performed, and the operability is improved.

FIG. 15 is a flowchart showing a process started by the control unit 44 when the input mode of the tablet 120 is switched to the tablet mode. In addition,
In this flowchart, the LED
Shows an example in which the LED is turned off and the LED is turned on in the command mode.

When the input mode of the tablet 120 is switched to the command mode, the control section 44 starts this processing and turns on the LED 71 (S201). Next, the control unit 44 starts a built-in timer (not shown) (S202). This timer is for saving power by preventing the LED 71 from staying lit.
Then, the control unit 44 detects whether an operation key has been input (S203). Then, when detecting that the operation key is detected in step S203, the control unit 44 detects whether the input operation key is the tablet function switching key 125 (S204). Then, when detecting that the input is the tablet function switching key 125, the control unit 44 switches the input mode of the tablet 120 to the tablet mode, turns off the LED 71, and ends this processing (S205).

When detecting that there is no input from the tablet function switching key 125 in step S204, the control unit 44 resets the count value of the timer (S206). When detecting that the operation key has not been input in step S203, the control unit 44 has passed 30 seconds or more since the input mode of the tablet 120 was switched to the command mode based on the count value of the timer. Is detected (S207). Then, when detecting that the count value of the timer is less than 30 seconds, the control unit 44 proceeds to step S2.
Return to 03, and when it is detected that it is 30 seconds or more, step
Proceed to S203. Therefore, the control unit 44 can turn off the LED 71 and prevent wasteful power consumption when there is no input from the operation keys for 30 seconds or more after the command mode is set, that is, when the LED 71 is turned on.

Also, the tablet mode may be used frequently depending on the operation mode.
Since the remote control device 114 automatically waits in the tablet mode, user operability is improved.

As described above, by using the tablet 120 for both pointer movement and command input, the number of operation keys required for the remote control device 114 can be reduced, and a simplified operation unit is provided. Can be configured. Thus, it is not necessary to select and operate a desired operation key from a large number of operation keys, and operability can be improved.

In this embodiment, the tablet 120 is used.
The above description has been made on the assumption that the various marks are formed by normal printing or the like. However, by applying a fluorescent paint or the like, the operation can be easily performed even in a dark room or the like. Further, the tablet 120 may be configured by a touch panel using a liquid crystal display device or the like, for example, and several types of marks may be switched and displayed by switching the driving of the liquid crystal depending on the operation mode. In this case, even if an input is made in the same tablet area, by selecting a command signal read from the command table 43 according to the mark displayed at that time, the number of commands that can be input by the tablet 120 is increased. May be. Also, the visibility of the mark may be improved by providing a backlight on the liquid crystal display device.
