Description

  The present invention receives a remote control signal (hereinafter abbreviated as a remote control signal) including control code information transmitted from a remote control signal transmission device (hereinafter abbreviated as a remote control), and an operation corresponding to the control code information The present invention relates to a remote control signal receiving device (hereinafter abbreviated as a remote control signal receiving device) which is a remote operation object for performing the control, and a control method thereof, and in particular, a remote control operation unit (hereinafter referred to as a key). Repeat that is sent from the remote control at a predetermined cycle in order to continuously perform a predetermined operation corresponding to the key when it is continuously operated (in the case of a key, when it is continuously pressed) The present invention relates to a control technique in a remote control signal receiving device when a signal is received.

  The remote controller internally generates control code information corresponding to the operated key in response to an operator's key operation (in response to a key press), and a remote control signal in which, for example, infrared light is modulated with this control code information Is transmitted from the light emitting circuit to the remote control signal receiver. On the other hand, the remote control signal receiving device, which is a remote operation target, receives the remote control signal transmitted from the remote control by the light receiving circuit, and then converts the control code information included in the remote control signal into a corresponding operation command. The operation according to is performed.

  Conventionally, as a format of a remote control signal transmitted from a remote controller used in a television receiver or an audio apparatus, for example, the format shown in FIG. 8 of Patent Document 1 is generally used (for convenience, this is used). Called generic format). When the operator continues to press down the keys of the remote controller using such a general format for a desired period, the remote controller performs control code information for the first time as shown in Patent Document 1. A remote control signal including the control code information is transmitted for the second and subsequent times, and only the repeat signal indicating continuous pressing that does not include control code information is repeatedly transmitted as a remote control signal until key-off is performed at a constant cycle T1 (about 100 ms). In response to this, the remote control signal receiving device continues the operation corresponding to the input key while the key is kept pressed.

  When the pressed key is released and the remote control enters the key-off state, the remote control stops transmitting a repeat signal. At this time, if the repeater signal transmitted from the remote controller is not received for a predetermined time (for example, 100 ms + α) longer than one cycle T1, the remote controller signal receiving device recognizes that the key is off and stops the continuous operation corresponding to the key. That is, it is detected that the repeat signal has disappeared for a predetermined period of time in software, and is recognized as a key-off of the remote controller, thereby stopping the operation. Here, the key-off determination takes a predetermined time longer than one cycle (repeat signal transmission cycle) T because, for example, a person crosses the optical path of the remote control signal, for example, the remote control signal on the remote control signal receiving device side. This is to improve the operability of the remote control by preventing the continuous operation from being stopped even if there is an unintentional interruption that interrupts for a moment. Of course, there is a case where the remote control signal is interrupted momentarily due to a shift in the transmission direction of the remote control signal from the remote control due to the hand shake of the operator.

As another technique for detecting remote control key-off during continuous operation, a command code for stopping the operation mode is transmitted from the remote control when the remote control key is off, and the operation of the remote control signal receiving device is stopped immediately after the key-off. This technique is disclosed in Patent Document 2.

  As described above, in the system using the general-purpose format of the remote control employed in a television receiver, audio device, household product, electronic device, machine, etc., `` unintentional operation stop '' caused by missed repeat signals In order to prevent this, a key-off authorization waiting time W, which is a predetermined time for the key-off determination, is provided. However, by providing this key-off authorization standby time W, it is possible to prevent unintentional operation stop, but it takes time from the key-off of the remote control to the operation of the key-off information of the remote control being certified on the remote-control signal receiving device side, Therefore, even when the operator intentionally stops the remote control operation, there is a problem that the response performance of the operation stop of the remote control signal receiving device is slowed down. In other words, for example, when the volume is turned up with the remote control, the volume has reached a predetermined level, so even if you release the key, it does not stop immediately, but stops one step or two steps at a higher volume. There was a problem that a defect occurred.

  As a countermeasure for this, for example, the transmission cycle T1 of the repeat signal at the time of continuous input is shortened, and accordingly, the key-off authorization waiting period W of the remote control on the remote control signal receiving device side is also shortened. It is also conceivable to improve the response to stop operation. However, when such a method is adopted, both software and electrical changes on the remote control side and the remote control signal receiving apparatus side are necessary. Further, with the change of the remote control signal format in which the transmission cycle of the remote control signal changes, there arises a problem that the compatibility of the remote control between the conventional remote control system and the new remote control system cannot be achieved.

  In addition, when the remote control signal receiving device is immediately stopped by transmitting a key-off code for stopping the operation mode when the remote control is key-off as disclosed in Patent Document 2, the remote control signal receiving device However, there is a problem that compatibility with a conventional remote control system is not achieved. Furthermore, both the remote control and the remote control signal receiving device need to be changed in software and electrical.

  The present invention has been made to solve the above-described problems of the prior art, and the object of the present invention is to perform a key-off instructing stop of continuous operation without changing the format of the remote control signal. An object of the present invention is to enable the remote control signal receiving device to have a response performance capable of quickly stopping a continuous operation and to prevent an operation stop due to a repeat signal being missed.

In order to achieve the above object, the present invention first transmits predetermined code information corresponding to a predetermined operation unit when a predetermined operation unit such as a predetermined key is continuously operated, and thereafter performs the predetermined operation. A remote control signal that transmits a repeat signal only in a predetermined transmission cycle that does not include the predetermined code information until a unit is released, receives a signal transmitted from a remote control, and performs a corresponding operation In the receiving device,
When a repeat signal that continues at a predetermined transmission cycle cannot be received from the remote control, the operation corresponding to the predetermined operation unit is temporarily stopped, and then a repeat signal is not received from the remote control within a predetermined standby time. The operation is completely stopped, and when the repeat signal is received within the predetermined waiting time, the operation is temporarily stopped and the operation before the suspension is restarted.

  As described above, in the present invention, if the repeat signal cannot be received even after the predetermined transmission period has elapsed, the remote control signal receiving apparatus immediately stops the operation, and then repeats again within the predetermined waiting time. If the signal can be received, the suspended operation is resumed. Otherwise, the operation is completely stopped, thereby preventing the operation from being stopped due to unintentional remote control signal reception interruption. It is possible to respond immediately to the stop instruction. The present invention relates to a device control technique according to a remote control signal in a remote control signal receiving device, and does not give any change to the remote control. Therefore, the remote control has compatibility with a conventional remote control. Can be built as a system.

  According to the present invention, it is possible to realize a quick response to an operation release (for example, key-off) on the remote control side when the operation unit (for example, a key) is continuously operated, which is a problem of a general remote control signal receiving device, and Thus, it is possible to maintain the function of preventing the malfunction of the conventional repeat signal from being missed, and further, it is not necessary to change the format of the remote control signal, so that the conventional remote control can be employed as it is.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 5 relate to a system including a remote control signal receiving apparatus according to an embodiment of the present invention. In each figure, parts having common functions are denoted by the same reference numerals, and those described once are repeated. The explanation is omitted.

  FIG. 1 is a diagram showing a configuration of a remote control system including a remote control signal receiving apparatus according to an embodiment of the present invention. As shown in FIG. 1, this remote control system includes a remote control 1 and a remote control signal receiving apparatus 10 that receives a remote control signal 6 transmitted from the remote control 1 using infrared rays or the like and performs an operation. ing.

  First, the configuration of the remote controller 1 and the remote control signal receiver 10 will be described. The remote controller 1 stores a direction key 2 that is input when operating the pointer 15 on the display device 14 of the remote control signal receiver 10 and a conversion table that is replaced with control code information corresponding to the key input by the operator. A memory 4, a microcomputer 3 that converts control code information generated by the conversion table into an electrical pulse signal and outputs the electrical pulse signal, and an infrared light emitting diode (not shown) built in the electrical pulse signal And a light emitting circuit 5 for transmitting a remote control signal. The memory 4 is usually built in the microcomputer 3. Although only the direction key 2 is shown in the remote controller 1, it goes without saying that another key group is arranged.

  The remote control signal receiving apparatus 10 includes a light receiving circuit 11 including an infrared light receiving IC that receives the remote control signal 6 transmitted from the remote control 1, and a conversion table and software that converts control code information included in the remote control signal into a corresponding operation command. The mounted microcomputer 12 and the display device 14 whose behavior is controlled by an operation command obtained by conversion by the microcomputer 12 are configured. The conversion table is stored in the memory 13 and the software is stored in a ROM (not shown). The memory 13 is usually built in the microcomputer 12.

  In the present embodiment, for convenience, the key for instructing the continuous operation of the remote controller 1 is, for example, the direction key 2, and the pointer 15 on the screen of the display device 14 is continuously moved by continuously pressing the direction key 2. Although the following description will be given, it goes without saying that the key for instructing the continuous operation in the present invention is not particularly limited to this. For example, a volume UP / DOWN key that is a key for instructing continuous operation may be used. In this case, a bar display for displaying the volume position in an analog manner and a numerical value for digital display are displayed on the screen of the display device 14.

  The display device 14 is a display device using a cathode ray tube, liquid crystal, plasma, or the like. Here, a pointer is displayed on the screen based on an operation command (here, display data) converted and generated from control code information by the microcomputer 12. 15 is moved. The movement of the pointer 15 on the screen corresponds to the operation (pressing) of the direction key 2 on the remote controller 1, and the pointer 15 is moved and displayed on the screen in response to the key pressing by the operator. Mark. Specific uses of the pointer 15 include, for example, an instruction of a selection position on a menu selection screen of a television receiver, a free cursor operated by a user when performing an internet operation on an internet-compatible television receiver, and the like. Can be mentioned. The free cursor operation is an operation of operating a cursor on a personal computer screen with a mouse.

  In this remote control system, when the operator presses or keeps pressing the direction key 2 on the remote controller 1, the pointer 15 on the display device 14 is moved as intended through the microcomputer 12, or the finger is moved from the direction key 2. The movement of the pointer 15 can be stopped by releasing the above. The process from the start of the continuous input process of the direction key 2 until the key-off of the direction key 2 is recognized and the movement operation of the pointer 15 on the display device 14 is stopped will be described in detail with reference to the drawings.

  First, the continuous operation of the remote control system will be described. FIG. 2 is a timing chart showing the operation of the remote control system, and FIG. 3 is a flowchart showing a processing flow of the remote control signal receiving apparatus 10.

  As shown in FIG. 2A, when the operator presses the direction key 2 of the remote controller 1 to turn it ON (20), the remote controller 1 starts from the light emitting circuit 5 first as shown in FIG. A remote control signal 30 including control code information corresponding to the direction key 2 is transmitted, and in response to this, the remote control signal receiving device 10 includes the received remote control signal 40 as shown in FIG. The microcomputer 12 sends a command to the display device 14 based on the control code information, and starts to move (50) the pointer 15 in the direction corresponding to the direction key 2, as shown in FIG. Now, as shown in FIG. 2A, when the direction key 2 of the remote controller 1 is continuously pressed (continuous ON; 21), the control code information is sent from the remote controller 1 as shown in FIG. 2B. Remote control signals 31a, 31b, 31c, 31d,... Consisting only of repeat signals meaning continuous pressing not included are repeatedly transmitted. In the following description, for convenience, a remote control signal including control code information is simply referred to as control code information, and a remote control signal including only a repeat signal is simply referred to as a repeat signal. The transmission cycle of the control code information 30 and the repeat signal 31 is T1 as shown in FIG.

  In the remote control signal receiving device 10, the microcomputer 12 outputs a command for instructing the continuous movement of the pointer 15 to the display device 14 by the received repeat signals 41a, 41b, 41c, 41d,. ), The pointer 15 performs the continuous operation 51 (continuous movement in the direction corresponding to the direction key 2).

  The processing operation of the remote control signal receiving apparatus 10 described above is shown by the processing flow in FIG. 3. While the direction key 2 on the remote control 1 is kept pressed, the repeat signal 31 is output at a cycle (transmission cycle) T1. It will be in the state which continues, and will enter into the continuous input process step S100 of FIG. Here, let tm be the elapsed time after receiving the repeat signal. First, in step S101, tm = 0 is set. Next, in step S110, it is checked whether or not the elapsed time tm is less than T1, and if tm is less than T1 (if YES in step S110), step S102. Then, after adding a predetermined sampling time Δt to the elapsed time tm, the process returns to step S110 to check the elapsed time again. In this way, steps S110 and S102 are repeated until the period T1 elapses after the previous repeat signal is received. When the elapsed time tm reaches the period T1, that is, when the period T1 has elapsed after receiving the repeat signal 41 (NO in step S110), the process proceeds to step S120 to determine whether or not there is a next repeat signal 41. To do. Here, since the direction key 2 is kept pressed, the next repeat signal is received. Therefore, it is determined that the continuous input is continued, the process proceeds to step S121, and the pointer 15 on the display device 14 is moved to the previous time. Then, the moving operation is continued in the same direction, and thereafter, the elapsed time tm is set to tm = 0 in step S122, and the process returns to step S110 again. This operation is repeated while the direction key 2 is kept pressed.

  Next, the operation of the remote control signal receiving apparatus 10 when the direction key 2 of the remote control 1 is kept pressed (continuous ON) and the direction key 2 is stopped and the key is turned off will be described.

FIG. 4 is a timing chart of the operation of the remote control system when the remote controller 1 is keyed off. As shown in FIG. 4A, when the direction key 2 of the remote controller 1 is turned from the continuous ON (21) state to OFF (22), as shown in FIG. At that time, transmission of the next repeat signal 31 _{i + 1} is stopped. At this time, as shown in FIG. 4C, the remote control signal receiving apparatus 10 receives the repeat signal 41 _i and confirms that there is no repeat signal 31 _{i + 1} after the T1. Is detected, the key is temporarily recognized, and the operation of the pointer 15 is turned off (52), as shown in FIG. Thereafter, the reception of the repeat signal 31 is continuously monitored during the standby period (predetermined standby time) W. If the repeat signal 31 is not received during the standby period W, the official recognition of the key-off is performed and the operation of the pointer 15 is performed. Is completely stopped (54).

  The processing of the remote control signal receiving apparatus 10 described above is shown in the flow of FIG. 3, while (21) while the direction key 2 of the remote control 1 is continuously pressed, as in the case of the continuous ON shown in FIG. Steps S102, S110, S120, S121, and S122 are repeated. If the directional key 2 is turned OFF (22) from this state, when the elapsed time tm becomes T1 and the process proceeds to step S120, the repeat signal 41 is not received and the process proceeds to step S130. In step S130, it is determined whether or not tm = T1. Here, since tm = T1, the process proceeds to step S131 to make a temporary key-off authorization. Next, in step S132, the operation of the pointer 15 is temporarily stopped. Proceeding to step S102, Δt is added to tm, and the process returns to step S110. Here, since tm has added Δt in step S102, tm> T1, and as a result, the process proceeds from steps S120 and S130 to step S140. In step S140, it is determined whether or not tm is equal to or greater than T2 (T2 = T1 + W). If tm <T2 (NO in step S140), the process proceeds to step S102, and Δt is added to tm. The process returns to step S110. This operation is repeated until tm reaches T2, and when tm ≧ T2 (when it becomes YES in step S140), the process proceeds to step S141, and the operation of the pointer 15 is completely stopped as a key-off official recognition. The input process is terminated (step S200).

  The above-mentioned T2 is a value that differs depending on each remote control system, and is particularly greatly influenced by the format of the remote control signal employed, the execution cycle of internal control on software, and the like. Accordingly, it is desirable that the value of T2 is set to a suitable value corresponding to each remote control system employing the present invention. For example, in this embodiment, as an example, when T1 = 108 ms, T2 is set to a value slightly more than twice T1, and W> T1 is set.

  Next, the operation of the remote control signal receiving apparatus 10 when the continuously transmitted repeat signal 31 cannot be normally received for some reason while the direction key 2 of the remote control 1 is kept pressed will be described.

FIG. 5 is a timing chart of the operation of the remote control system when a repeat signal transmitted from the remote controller 1 is missed on the remote control signal receiving device side. 5A shows a state in which the direction key 2 of the remote controller 1 is continuously pressed (continuous ON; 21) as in the case of the continuous ON shown in FIG. 2 and described above. The repeat signal 31 is continuously transmitted at the transmission cycle of T1 ((b) in FIG. 5). During the continuous output of the repeat signal 31, for example, when the pointing direction of the remote control 1 is momentarily deviated from the remote control signal receiving unit of the remote control signal receiving device 10 due to shaking of the operator's hand, for example (c) of FIG. As shown in FIG. 4, the remote control signal receiving apparatus 10 cannot receive the repeat signal 31 _{i + 1} and detects that the repeat signal is lost. As a result, the key-off authorization process is started, and the movement of the pointer 15 on the screen is paused when T1 elapses after receiving the repeat signal 41 _i in the same manner as described above with reference to FIG. Let Thereafter, a standby period W is entered, and a state of waiting for official recognition of key-off is entered, and the pointer 15 also continues in the pause state (53). However, in this case, since the operator keeps pressing the direction key 2 of the remote controller 1, the repeat signal 31 _{i + 2} is continuously transmitted from the remote controller 1, and the remote control signal receiver 10 receives the repeat signal 31 _{i + 1.} Although it was missed, the repeat signal 31 _{i + 2} is normally received ((c) in FIG. 5). At this time, the remote control signal receiving apparatus 10 is in the standby period W, and has not yet officially authorized the key-off of the remote control 1 yet. Therefore, the remote control signal receiving device 10 that has been in the temporary certification period sends a command to the display device 14 to resume (55) the movement of the temporarily stopped pointer 15 by re-receiving the repeat signal 41 _{i + 2} . As a result, the pointer 15 on the screen continues to move in the same manner as before the pause (56 in FIG. 5D).

When the processing of the remote control signal receiving apparatus 10 described above is shown in the flow of FIG. 3, while the repeat signal is continuously received, the processing of steps S102, S110, S120, S121, and S122 is repeated to receive the remote control signal. If it is determined in step S120 that the repeat signal 31 _{i + 1 has not been received due to} the skip of the repeat signal 31 _{i + 1} of the apparatus 10, the process proceeds to steps S130, S131, and S132 in order to determine (detect) the key-off of the remote controller. Thereafter, during the standby period W, steps S102, S110, S120, S130, and S140 are repeated. If the next repeat signal 31 _{i + 2} is received during this period, it is determined that the repeat signal is received in step S120. Proceeding to step S121, the movement of the pointer 15 that has been paused is thereby resumed. Thereafter, as long as a repeat signal is received, steps S102, S110, S120, S121, and S122 are repeated.

  Since the key-off detection process of the remote controller described above is performed using the fact that a repeat signal is periodically transmitted at the time of continuous input (when the key is continuously pressed), the standby period (standby time) W is at least It is necessary to set a time longer than the transmission cycle T1 of the repeat signal transmitted from the remote controller 1. If the waiting period W is not provided, it can be said that there is a risk that the operation of the pointer 15 may stop against the user's intention due to a repeat signal being missed by an erroneous operation.

  When the operation of the pointer 15 continues during the standby period W as in the conventional remote control system described above, the operation stops at a position far beyond the position where the operator wants to stop the pointer 15. However, in the present embodiment, the pointer 15 can be immediately stopped at the timing when the direction key 2 of the remote controller 1 is released. Further, even when the remote control signal receiving apparatus 10 misses the reception of the repeat signal for some reason, the operation can be resumed when the repeat signal is received again, so that an unintended operation stop can be prevented.

  Further, the present invention can be realized by diverting the conventional remote controller as it is and changing only the software on the remote controller signal receiving device 10 side, so that the compatibility with the conventional remote controller can be maintained, and the cost is reduced. The burden is very small.

  In the embodiment of the present invention described above, the four-direction direction key 2 is used as the continuous operation key. However, the present invention is not limited to this, and the direction key 2 has four or more directions. The present invention can also be applied to devices that have other devices such as joysticks and touch sensors. In addition, the remote control can be applied not only to a general button type but also to a touch panel type software remote control in which buttons (keys) are displayed on a display device such as a liquid crystal panel (in this case) Continuously touching a predetermined key on the touch panel corresponds to continuous operation). In addition, the keys on the remote controller are not limited to the direction keys described in the above embodiment, and for example, operation keys on other remote controllers corresponding to other continuous input operations such as volume UP / DOWN keys in home AV equipment products. It is also applicable to.

  In addition to the keys, the operation unit for continuous input operation of the remote control is turned on at a predetermined operation amount and automatically returns to the off position when the operation is released. For example, other operation units such as a lever switch and a pull switch Even so, the present invention is applicable.

  Further, in the embodiments of the present invention described above, an apparatus having a display device is taken as an example of a remote control signal receiving device, but the remote control signal receiving device of the present invention as a remote operation target is limited to this. For example, the present invention can also be applied to mechanical devices such as model cars, model airplanes, and robots.

  Further, the application of the present invention is not limited to the general-purpose format of the remote controller described above, but can be applied to other types of remote-control formats, for example, a format with a short or long transmission cycle of a remote-control signal at the time of continuous input In this case, the same effects as those of the embodiment described above can be obtained.
