[First Embodiment] In the first embodiment, a clock unit 20, a time setting unit 21, a mode setting unit 22, and a remote control device 30 shown in FIG.
Clock section 38, time setting section 39, mode setting section 4
0 is not used. That is, it is possible to adopt a configuration in which these are deleted.

Now, when the power of the TV body 10 is turned on,
It is assumed that the TV is displayed by the TV control unit 15 controlling the tuner unit 16 and the image display unit 17.

In this state, the TV main unit 10 periodically checks at regular intervals from the communication control unit 13 via the transmission unit 12 to check whether there is a remote control device 30 connectable to itself. Then, an existence confirmation signal without an ID (for example, data in which “0” is set in the ID unit 101 shown in FIG. 3) is transmitted.

Here, the remote control device 30 is
The following description will be made separately for a case where it exists within a connectable range and a case where it does not exist.

(1) When the Remote Control Device 30 Exists in a Range Connectable to the TV Main Unit 10 In this case, the remote control device 30 receives the data (existence confirmation signal) transmitted from the TV main unit 10 by the receiving unit 31. The information is passed to the communication control unit 35. The communication control unit 35 checks the ID unit 101 (see FIG. 3) of the received data, and recognizes that the received data is data for existence check if there is no ID. The ID number (arbitrary number from 1 to 15) stored in the ID number storage unit 36 is stored in the
D unit 101 (see FIG. 3), and transmits the transmission data (existence confirmation response signal) via the transmission unit 32 to the TV main unit 10.
Send to

The TV main unit 10 recognizes the data (existence confirmation response signal) received by the receiving unit 11 in the communication control unit 13 and if the ID number 101 other than “0” is added to the data ID unit 101. At the same time, the ID number is stored in the ID storage unit 18, and at the same time, a timer of a certain value determined in the timer setting unit 19 is set in the timer counting unit 14. It is assumed that the timer value set in the timer counting unit 14 decreases as time elapses unless resetting is performed.

Next, when data is transmitted from the TV main body 10, first, it is checked whether or not the ID number is stored (set) in the ID storage unit 18. If the ID number is set, the ID number is changed. The transmission data is set in the ID section 101 (see FIG. 3) of the transmission data, and the timer value set in the timer count section 14 is set in the timer section 102 (see FIG. 3) and transmitted from the transmission section 12.

Remote control device 3 which has received this transmission data
0 is the I set in the ID part 101 of the received data.
The ID check unit 37 checks whether the D number matches its own ID number, and if they match, the timer value of the received data set in the timer unit 102 (see FIG. 3) is used as the timer count unit. At the same time as setting to 34
The power switch 42 of the circuit section 41 is turned on. Then, the ID number stored in the ID number storage unit 36 is
The data set again in the D section 101 (see FIG. 3) is transmitted from the transmission section 32 to the TV main body 10. The timer value set in the timer count unit 34 is assumed to decrease as time elapses, unless reset, similarly to the timer count unit 14 of the TV main body 10.
In the remote control device 30, after the power switch 42 of the circuit unit 41 is turned on, by pressing a button held by the button input unit 33 of the remote control device 30, the channel or volume of the TV main body 10 is pressed. Can be controlled.

In the case of the above configuration, as long as the remote control device 30 is in a range connectable to the TV main unit 10, the unique I / O possessed by the remote control device 30 is provided.
By allowing the TV body 10 to recognize the D number, the TV body 10 can be controlled from the remote control device 30.

(2) When the remote control device 30 is out of the connectable range with the TV main unit 10 Even when the remote control device 30 is out of the connectable range,
The transmission unit 12 of the TV main unit 10 periodically transmits an existence confirmation signal without an ID (for example, the ID unit 1 shown in FIG. 3).
01 is set to "0"). However, in this case, since the receiving unit 11 does not receive data from the remote control device 30, the timer value is not reset, and the timer value set in the timer counting unit 14 keeps decreasing. Then, when the timer value becomes “0”, the TV main body 10 automatically turns off its own power, thereby stopping TV display and data transmission / reception thereafter.

Similarly, in remote control device 30, T
When the data from the V main body 10 is not received, the timer value set in the timer count unit 34 keeps decreasing, and when the timer value becomes “0”, the power switch 42 of the circuit unit 41 is turned off. Is turned off to stop the function of the button input unit 33 thereafter.

Next, the processing of the above (1) and (2) for each case will be described in more detail with reference to the flowcharts shown in FIGS. However, FIG.
FIG. 5 is a flowchart showing the transmission operation of the TV main unit 10.
FIG. 6 is a flowchart showing the transmission / reception operation of the remote control device 30.

First, with reference to the flowchart shown in FIG. 4, the flow of data related to the transmission of the TV main body 10 will be described.

First, the power of the TV body 10 is turned on in step S1, and it is checked in step S2 whether the power of the TV body 10 is turned on. As a result, if the power is on, the process proceeds to step S3, and if the power is off, the operation ends.

In step S3, it is checked whether or not the ID number of the remote control device 30 to be transmitted is set in the ID storage unit 18. As a result, if the ID number has not been set, the process proceeds to step S4,
“0” indicating that the ID is not set is set in the ID unit 101. On the other hand, if the ID number has been set, the process proceeds to step S5, the ID number is set in the ID unit 101, and the timer value set in the timer count unit 14 in the next step S6 (this will be described later). Is set in the timer unit 102 (see FIG. 3).

In the next step S7, data 105 (see FIG. 3) including the ID section 101 and the timer section 102 is transmitted, and the process returns to step S2.

As a result of the series of processing in steps S1 to S7, as long as the power of the TV main unit 10 is in the ON state, the TV main unit 10 periodically transmits data (existence confirmation signal).

Next, the flow of data related to the reception of the TV main unit 10 will be described with reference to the flowchart shown in FIG.

In step S11, it is checked whether or not there is a reception at regular intervals. If the data has been received, the process proceeds to step S12 to check whether or not the ID number of the remote control device 30 is set in the ID part 101 of the received data. As a result, if an ID number other than “0” is set in the ID section 101, the process proceeds to step S13, where the set ID number is set to I
D storage unit 18, and in the next step S14, a timer setting unit 1 that can be arbitrarily set by the user
The timer value set to 9 is set in the timer count unit 14, and the process returns to step S11.

On the other hand, in step S12, ID unit 101
If the ID number has not been set ("0" has been set), the process returns to step S11.

If it is determined in step S11 that there is no reception, the flow advances to step S15 to check whether or not the ID number is stored in the ID storage unit 18. As a result, when the ID number is not stored, it is determined that the communication between the TV main body 10 and the remote control device 30 has not been performed yet, and the process returns to step S11.

On the other hand, if it is determined in step S15 that the ID number is stored, the flow advances to step S16 to check whether or not the count value of the timer counting unit 14 is "0". As a result, when the count value of the timer count unit 14 is not “0”,
The process returns to step S11 and waits for received data again. On the other hand, when the count value of the timer count unit 14 is “0”, the process proceeds to step S17, and the power of the TV body 10 is turned off.

Next, with reference to the flowchart shown in FIG. 6, the flow of data related to transmission and reception of the remote controller 30 will be described.

In step S21, it is periodically checked whether or not there is a reception. If there is reception, the flow advances to step S22 to check whether or not an ID number is set in the ID part 101 of the received data. Check and ID
If a number has been set, the process proceeds to step S23, where it is checked whether the ID number matches its own ID number stored in the ID number storage unit 36.

As a result, the I
If the same ID number as the D number is set in the ID section 101 (if determined to be Yes in step S23), the process proceeds to step S24, and the value of the received data set in the timer section 102 is set in the timer. Counting section 34
, And in the next step S25, the power switch 42 of the circuit section 41 is turned on, and the process proceeds to step S26.

On the other hand, if the received data does not have an ID number set in step S22, or if it is determined in step S23 that the received data has a different ID number, the process also proceeds to step S26.

In step S26, the ID number (ID number stored in ID number storage section 36) held by remote controller 30 is set in ID section 101, and the data is transmitted in step S27.

On the other hand, if it is determined in step S21 that there is no reception, the flow advances to step S28 to check whether or not the count value of the timer count unit 34 is "0". As a result, if the count value of the timer count unit 34 is not “0”, the process returns to step S21 and waits for received data again. On the other hand, when the count value of the timer counting unit 34 is “0”, the process proceeds to step S29, where the remote control device 30
The power switch 42 of the circuit section 41 is turned off.

As described above, according to the first embodiment, the remote control device 30 notifies the TV main body 10 of its own presence by constantly transmitting data from the transmission section 32 of the remote control device 30 to the TV main body 10. can do. Further, the reception unit 31 confirms transmission from the TV main body 10 and
Since the D confirmation unit 37 compares the data with the ID number held by the D confirmation unit 37, it is possible to determine whether the received data has been transmitted to itself. Further, the time desired by the user can be set in the timer count section 34 of the remote control device 30, so that the remote control device 30
The user can freely set how long the remote control device 30 should be turned off after going out of the communication range with 0. Furthermore, since the power supply of the circuit portion of the remote control device 30 itself is turned off, it is effective for power saving of the remote control device 30.

In the TV main unit 10, the receiving unit 1
By receiving the data transmitted from the remote control device 30 in 1, it is possible to recognize that the remote control device 30 exists within a communicable range. Further, by providing the ID storage unit 18, even when a plurality of remote control devices exist within a communicable range, one remote control device as a communication partner can be recognized. Further, by setting the time data transmitted from the remote control device 30 in the timer counting section 14, when the set time has elapsed since the remote control device 30 has gone out of the communication range with the TV main body 10, The power of the TV body 10 can be turned off.

The TV main body 10 further includes a clock unit 20 for recognizing time and a time setting unit 2.
1 is further provided. Thus, when the user sets an arbitrary time using the remote control device 30, it is possible to turn off both the TV main body 10 and the remote control device 30 at the set time.

Next, the processing in the second embodiment will be described with reference to the flowcharts shown in FIGS. However, FIG. 7 is a flowchart showing the time setting and the transition operation to the power-off in the remote control device 30, and FIG. 8 is a flowchart showing the time setting and the transition operation to the power-off in the TV main body 10.

First, with reference to the flow chart shown in FIG. 7, the operation of setting the time in the remote control device 30 and shifting to the power-off state will be described.

However, as in the first embodiment, also in the second embodiment, the TV main unit 10 is powered on and the TV control unit 15 operates the tuner unit 16 and the image display unit 1.

First, in step S31, the remote controller 30
The power switch 42 of the circuit section 41 is turned on, the button input from the button input section 33 is made valid, and the control of the TV main body 10 by the remote control device 30 is enabled.

In the next step S32, it is checked whether or not the user has set the time. As a result, if there is a setting, the process proceeds to step S33; otherwise, the process proceeds to step S35.

In step S33, the set time is set in the time setting section 39. Regarding the time setting, not only when a new time is set, but also when there is a change in the set time, if the user has set the time in order to make the change effective, Time setting unit 39
Update the contents of

In step S34, the time set by the user is set in the time setting unit 104 (see FIG. 3).
The data is transmitted to the TV main body 10.

In the next step S35, by comparing the current time measured by the clock section 38 with the time set in the time setting section 39, it is checked whether or not the set time has come. As a result, if the set time has not come, the process returns to step S32 and the above check is repeated. On the other hand, if the set time has come, the process proceeds to step S37 (step S36 will be described later), the power switch 42 of the circuit unit 41 of the remote control device 30 is turned off, and the subsequent button input unit 3

Next, with reference to the flowchart shown in FIG. 8, the operation of setting the time and shifting to the power-off in the TV main body 10 will be described.

First, in step S41, the power of the TV body 10 is turned on. Thereby, transmission and reception with the remote control device 30 are possible.

In the next step S42, the remote controller 3
Check if there is a reception from 0. As a result, when there is no reception, step S42 is repeated again. On the other hand, when the reception is made in step S42 (when it is determined as Yes), the next step S43
Then, it is checked whether the time is set in the received data time setting unit 104 (see FIG. 3). As a result, if the time-set data is received,
In the next step S44, the time is set in the time setting unit 21 of the TV main body 10, and the process proceeds to step S45. On the other hand, if the time is not set in the received data in step S43, the process directly proceeds to step S45.

In step S45, the current time measured by the clock unit 20 is compared with the time set in the time setting unit 21 to check whether or not the set time has been reached. As a result, if the set time has not come, the process returns to step S42 and the above check is repeated. On the other hand, if the set time is reached,
Proceeding to step S46, the power of the TV body 10 is turned off by itself.

As described above, according to the second embodiment, since the time desired by the user can be set in the time setting section 39 of the remote control device 30, the set time is compared with the time measured by the clock section 38. Thus, the power of the remote control device 30 can be turned off at the time set by the user regardless of the state or the location of the remote control device 30 (inside or outside the communication range).

Also, in the TV main body 10, the time data transmitted from the remote control device 30 is stored in the time setting section 2.
By setting it to 1, the power of the TV body 10 can be turned off at the time set by the user by comparing the set time with the time measured by the clock unit 20.

The processing operation of the second embodiment is a processing operation in the case where the TV main unit 10 includes the clock unit 20 as in the case of the remote control device 30. Next, the TV main unit 10 controls the clock unit 20. A processing operation in a case where the information processing apparatus is not provided will be described as a third embodiment.

[Third Embodiment] The processing in the third embodiment will be described with reference to the flowcharts shown in FIGS. However, FIG. 7 is a flowchart used in the second embodiment, but the third embodiment has a configuration in which step S36 indicated by a broken line in the figure is added to this flowchart. FIG. 9 is a flowchart showing an operation of shifting the power of the TV main body 10 to off.

First, with reference to the flowchart shown in FIG. 7, the operation of setting the time and shifting to power-off in the remote control device 30 will be described.

As can be seen from the flowchart, the processing of remote control device 30 is basically the same as that of the second embodiment, except that the circuit portion of remote control device 30 in step S37 is different. Before turning off the power switch 42 of 41, in step S36, the data of the power-off state (for example, “0” is set to both the 12th bit and the 13th bit) in the mode setting unit 103 (see FIG. 3). ) Is set and transmitted to the TV body 10.

In the TV body 10 receiving this data,
As shown in FIG. 9, in step S51, the remote control device 30
Is checked, and if received, the mode setting unit 103 of the received data is determined in the next step S52.
Is "00" (power off). If no data is received from the remote control device 30 in step S51, or if the mode setting unit 103 of the data checked in step S52 is not "00", the process returns to step S51 again and waits for the next data.

On the other hand, if the value of the mode setting unit 103 of the received data is “00” in step S52,
Proceeding to step S53, the power of the TV body 10 is turned off.

As described above, according to the third embodiment, T
Even when the V body 10 does not have the clock section 20, the power of the TV body 10 can be turned off at the time set by the user using the data transmitted from the remote control device 30.

[Fourth Embodiment] In the fourth embodiment, T
V main body 10 has the circuit configuration shown in FIG. 1, and remote control device 30 has the circuit configuration shown in FIG.

That is, in the fourth embodiment, the TV body 1
By providing the mode setting unit 103 shown in FIG. 3 at the head of data transmitted and received between the remote control device 30 and the remote control device 30, T
The mode of the V body 10 can be switched. Specifically, an operation mode in which the power is turned off when no data is received for a certain time (timer value set to the timer count value), which is the processing operation of the first embodiment (hereinafter, a certain time) Mode), and an operation mode in which the power is turned off at a predetermined time (time set in the time setting unit), which is the processing operation of the second embodiment (hereinafter, a specific time mode). Switching).

That is, the remote control device 30 is provided with the mode setting section 40, and can set a fixed time mode or a specific time mode according to the user's intention. When data is transmitted from the remote control device 30 to the TV main body 10, the TV main body 10 checks the mode setting section 103 (see FIG. 3) of the received data,
The mode set in the mode setting unit 103 is set in the mode setting unit 22. Then, according to the mode set in this way, the TV main body 10 and the remote control device 30 are
Shift to power off state.

The mode switching will be described with reference to the flowcharts shown in FIGS. Note that FIG. 10 is a flowchart showing the mode switching process on the remote control device 30 side, and FIG.
6 is a flowchart showing a mode switching process on the side.

First, the mode switching processing operation on the remote control device 30 will be described with reference to the flowchart shown in FIG.

In step S61, it is checked whether or not something has been set in the mode setting section 40 by the user. If not set, the process of step S61 is repeated. On the other hand, if it has been set, the process proceeds to step S62.

In step S62, it is checked whether the set mode is the fixed time mode. If the mode is the fixed time mode, "10" is set in the mode setting section 103 shown in FIG. 3 in step S63. .

On the other hand, if the set mode is not the fixed time mode in step S62, the flow advances to step S64 to check whether the set mode is the specific time mode. As a result, in the case of the specific time mode, in the next step S65,
“01” is set in the mode setting unit 103 shown in FIG. If it is determined in step S64 that the mode is not the specific time mode, "11" is set in the mode setting unit 103 in the next step S66. Note that "0
“0” is used for a power-off command from the remote control device 30 to the TV main body 10.

Thus, in steps S63, S65, and S66, the mode setting unit 10
When the data is set in No. 3, the process proceeds to the next step S67, the data is transmitted to the TV main body 10, and the process ends.

Next, the mode switching processing operation on the TV main body 10 side will be described with reference to the flowchart shown in FIG.

The TV main body 10 repeats the step S71 until there is a reception from the remote control device 30. And
If the transmission data from the remote control device 30 has been received, the process proceeds to step S72 to check the received data. As a result, if the mode setting unit 103 is “10”, the process proceeds to step S73, and the mode is set in the mode setting unit 22 for a certain time.

On the other hand, if the mode setting unit 103 is not "10", the flow advances to step S74 to check the received data again. As a result, the mode setting unit 103 sets “0
If “1”, the process proceeds to step S75, where the mode setting unit 2
Set the specific time mode to 2.

On the other hand, if the mode setting unit 103 is not “10”, the process proceeds to step S 76, and information that “no mode is designated” is transmitted to the mode setting unit 2.
Set to 2.

Thus, in steps S73, S75 and S76, the mode setting section 22
When the setting of each piece of information is completed, the process proceeds to the next step S77, and the process ends.

It should be noted that when either the fixed time mode or the specific time mode is set in the mode setting section 22, the TV
The process of shifting the main body 10 and the remote control device 30 to the power-off state is the same as the method described in the first and second embodiments, and a description thereof will be omitted.

As described above, according to the fourth embodiment, by providing mode setting section 40 on remote control device 30, the mode can be switched by the user, and the data transmitted from remote control device 30 can be transmitted. The mode of the TV main unit 10 can be switched by receiving the setting in the TV main unit 10 and storing the set value in the mode setting unit 22 provided on the TV main unit 10 side.
