  In FIG. 1, 100 is a remote control transmitter used by a remote control user, and 200 is a video recorder device to be remotely controlled by the remote control transmitter.

  The remote control transmitter 100 includes a remote control key input means 101, a transmission means 102, a reception means 103, and a light emission processing means 104.

  The video recorder device 200 is, for example, an HDD (Hard Disk Drive) / DVD recording / playback device, and includes a receiving unit 201, a device control unit 202, a remote control key pressability calculation unit 203, a light emission control unit 204, and a transmission unit 205. And is composed of.

  The operation of the remote control transmitter 100 configured as described above will be described.

  A plurality of remote control keys are provided in the remote control transmitter 100, and the remote control key input means 101 supplies the remote control key input signal A1 to the transmission means 102 by each input operation. The transmission means 102 converts the remote control key input signal A1 into an infrared remote control key input signal B1 and transmits it to the video recorder device 200. As a result, the transmission means 102 generates an infrared remote control key input signal B1 for controlling the video recorder device 200 in response to the input of the remote control key.

  On the other hand, the receiving means 103 provided in the remote control transmitter 100 receives the infrared light emission control signal G1 from the video recorder device 200 and converts it into the light emission control signal H1. In response to the light emission control signal H1, the light emission processing means 104 causes the plurality of remote control key-attached LEDs to emit light with multi-level luminance. Thus, when the infrared light emission control signal G1 is received from the video recorder device 200, the plurality of LEDs attached to the remote control keys emit light at multi-level luminance accordingly.

  An operation of the video recorder device 200 of FIG. 1 will be described.

  The receiving means 201 provided in the video recorder device 200 receives the infrared remote control key input signal B1 transmitted from the remote control transmitter 100, converts it into the remote control key input signal C1, and supplies it to the device control means 202. The device control means 202 determines the state of the video recorder device 200 after controlling the video recorder device 200 from the remote control key input signal C 1, and supplies the video recorder device status code D 1 to the remote control key pressability calculation means 203. The remote controller key pressability calculation means 203 is one by one from the information on the possibility of state transition determined from the general operation method of the video recorder device 200 and the state transition history of the video recorder device 200. Two remote control key pressability information E1 is calculated and provided to the light emission control means 204.

To supply. The transmission means 205 converts the light emission control signal G1 into an infrared light emission control signal G1 and transmits it to the remote control transmitter 100. As a result, the video recorder device 200 receives the infrared remote control key input signal B1 from the remote control transmitter, so that the remote control user has information for causing the remote control key attached LED to emit light so that the remote control key can be easily distinguished. The signal G1 is transmitted to the remote control transmitter.

  The operation of the bidirectional remote control system of the present invention configured as described above will be described with reference to FIG.

  FIG. 2 is a flowchart showing periodic processing of the video recorder device 200 of FIG.

  In FIG. 2, the device control unit 202 first determines whether or not the power is turned on (S1). If the power is turned off, the determination is no and the process is terminated, and the power is turned on. If so, it is determined whether or not the remote control key input signal C1 is supplied to the device control means 202 (S2). If the remote control key input signal C1 is not supplied to the device control means 202, the determination is no and the process is terminated. If supplied, the determination is yes and the state of the video recorder device 200 is determined to determine the status code D1. Is obtained (S3). Next, using the status code D1, it is determined whether or not the video recorder device 200 has made a transition from the previous state by operating the remote control transmitter 100 (S4). If the state transition does not occur due to the operation of the remote control transmitter 100, the determination is no and the process is terminated. If the state transition occurs due to the operation of the remote control transmitter 100, the calculated state code D1 may be pressed. It supplies to the calculation means 203. In this way, unnecessary addition of state transition history due to state transitions that do not depend on the operation of the remote control transmitter 100 is prevented.

  The remote control key pressability calculation means 203 can press the remote control key based on the state transition possibility information determined from the general operation method of the video recorder device 200 and the state transition history of the video recorder device 200. Sex information E1 is calculated (S5).

  The light emission control means 204 determines what luminance is to be emitted for each remote control key from the remote control key pressing possibility information E1, and converts the information into a remote control key LED light emission control signal F1 (S6). ).

  The transmission means 206 converts the remote control key LED light emission control signal F1 into an infrared light emission control signal H1, and transmits it to the remote control transmitter 100 (S7).

  The video recorder device 200 waits for an operation from the remote control transmitter by repeating the processes of steps S1 to S7 in a predetermined cycle.

  FIG. 3 is a flowchart showing in detail the process of step S2 of FIG. 2, and FIG. 4 shows the configuration of the status information of the video recorder device 200 used in step S3. FIG. 5 is a status code table used in step S3- (n + 1) of FIG. The status code table is created in advance using status information in order to represent the status of the video recorder device 200 as a status code value.

  In FIG. 4, the status information is information indicating the status of the video recorder device 200 and is composed of information used by the remote control key pressability calculation means 203 to calculate the remote control key pressability information E1.

  In FIG. 3, step S3 is composed of n steps from step S3-1 to S3-n and the last step S3- (n + 1), and the device control means 202 is from step S3-1 to S3-n. The current state of the video recorder device 200 is input to the state information.

  In step S3-1, the device control unit 202 inputs the current remaining HDD capacity in the status information, and proceeds to step S3-2.

  In step S3-2, the device control unit 202 inputs the current time in the status information, and proceeds to the next step.

  From the next step to step S3-n, the current state of the video recorder device 200 is input to the state information in the same manner as in steps S3-1 and S3-2. Thereby, after executing step S3-n, the state information holds all the information until it can be determined what state the video recorder device 200 is in. In step S3- (n + 1), the state information input from step S3-1 to step S3-n is compared with each state determined in advance in the state code table of FIG. As a result, since the current status code of the video recorder device 200 can be obtained, it becomes the value of the status code D1. For example, when the HDD remaining amount of the video recorder device 200 is 50 GB at 9:00 am, and the key of the remote control key number 111 of the remote control transmitter 100 is pressed, 50 GB is input to the status information in step S3-1 and continued. In step S3-2, time information is input one after another, such as time 9:00 is input to the state information. Finally, in step S3- (n + 1), the state information input up to step S3-n. And the status code table of FIG. 5, the value of the status code D1 of the video recorder device 200 is required to be 1.

  In step S4 of FIG. 2, the device control means 202 determines whether or not the video recorder device 200 has caused a state transition from the previous state by referring to the previous state code value and the value of the state code D1 that are held. can do. If a state transition has occurred, the determination is yes, the previous state code value held by the device control means 202 is rewritten with the changed state code D1, and the process proceeds to the next step S5. If the value of the status code D1 has not changed from the previous status code value, the determination is no and it is determined that no state transition has occurred, and the process ends.

  FIG. 6 is a flowchart showing details of the processing for calculating the remote control key press possibility in step S5, FIG. 7 shows the contents of the remote control key press possibility information E1 calculated in step S5, and FIG. 8 shows step S5- 2 is a general pressability possibility table for each remote control key used in 2;

  The remote control key pressing possibility information E1 in FIG. 7 represents the case where there are remote control keys from the remote control key 111 to the remote control key 164, and indicates the value of the pressing possibility for each remote control key obtained in step S5. Enter.

  8 is determined in advance for all the status code values of the video record device 200 whose status code values are 1 to m, and the video recorder in the status indicated by the status code. The possibility of pressing in the general usage of the device 200 is obtained in advance for each remote control key, and is made into a table. A value having a pressing possibility value of 0 indicates that there is no point in pressing the remote control in that state. The post-press state code in FIG. 8 indicates a state code to which the state transition is made by pressing the remote control key when the video record device 200 is in the state indicated by the state code. Thus, the state code after the state transition can be obtained using the current state code and the remote control key number pressed at that time.

  In FIG. 9, the state transition history indicates the number of transitions from the state code of the video recorder device 200 to the next state code. Thereby, the possibility of transition from one state code to the next state code can be acquired.

  In FIG. 6, in step S5-1, the number of transitions in the state transition history of FIG. 9 is determined by referring to the previous state code held by the remote control key pressability calculation means 203 and the supplied state code D1. Increase. By repeating this, the possibility of more accurate state transition of the video record device 200 can be acquired. Thereafter, the previous status code value held by the remote controller key pressability calculation means 203 is rewritten to the value of the status code D1, and the process proceeds to the next step S5-2.

  In step S5-2, the remote control key pressability calculation means 203 searches the remote code key pressability table for each status code in FIG. 8 using the value of the status code D1 as a key, and matches the value of the status code D1. The general pressing possibility value for each remote control key is input to the remote control key pressing possibility information E1 one by one. By doing so, the general possibility of pressing each remote control key in the state of the video recorder device 200 indicated by the status code is obtained.

  In step S5-3, the remote controller key pressability calculation means 203 obtains a status code that is likely to transit to the current status code D1 by referring to the status transition history of the video recorder device 200 in FIG. it can. The remote control key pressability value of the remote control key pressability information E1 is increased with respect to the remote control key that makes a transition to a status code that has a high possibility of transition. The remote control key to be changed to the state code having a high possibility of transition can be obtained by referring to the remote code key general pressing possibility table for each status code in FIG. For example, if the current state code is 1 and the next state code with a high possibility of transition is 2 and m with reference to the state transition history of FIG. 9, the state code remote control key general press possibility table of FIG. After the state code 1 line is pressed down, the state code is 2 and m, and the remote control key for the state code 2 is obtained by obtaining the remote control key for that line. It can be seen that the remote control key is 164. For these remote control keys, the remote control key pressability value of the remote control key pressability information E1 is increased.

  From the above steps S5-2 and S5-3, remote control key pressing possibility information E1 can be calculated.

  In step S6 of FIG. 2, the light emission control means 204 emits the LED of the remote control key with high brightness in order of the remote control user in order of increasing remote control key pressability value in the remote control key pressability information E1. The light emission control signal F1 obtained by converting the remote control key pressing possibility information E1 is supplied to the transmission unit 205.

  In step S7, the transmission means 205 converts the light emission control signal F1 into an infrared light emission control signal G1 and transmits it to the remote control transmitter 100.

  FIG. 10 is a flowchart showing interrupt processing of the remote control transmitter 100 of FIG.

  As shown in FIG. 10, first, the receiving means 103 of the remote control transmitter 100 receives the infrared light emission control signal G1 from the video recorder device 200 in step S8, and proceeds to step S9.

  Next, in step S9, the receiving means 103 determines whether or not the result of converting the received infrared light emission control signal G1 is the light emission control signal H1. If the determination is no, the process is terminated. The process proceeds to S10.

  Finally, in step S10, the light emission processing means 104 adjusts the luminance of each LED attached to the remote control key as indicated by the light emission control signal H1 to emit light.

  FIG. 11 is an explanatory diagram showing light emission of the remote control key according to the first embodiment of the invention of FIG.

  In FIG. 11, a remote control transmitter / receiver 110 made of a material that transmits a control signal is provided at the upper end of the remote control transmitter 100, and an infrared light emitting unit and a receiver of the transmission means 102 of the remote control transmitter 100 are provided therein. An infrared light receiving unit of the means 103 is provided. Remote control keys 111 to 164 are provided on the operation surface of the remote control transmitter.

  For example, when the power is turned on in the video recorder device 200, the remaining amount of the HDD is 0.5 GB, the time is 7 am, and the state code j in which 4 channels are output to the TV is input with the remote control key 121. Suppose that the TV output is switched to 8 channels. Immediately after switching, first, status information is input in steps S3-1 to S3-n of FIG. 3, and in step S3- (n + 1), each condition is checked from the status code table of FIG. Desired. The obtained state code value k is input to the state code D1, and the process proceeds to the next step S4 in FIG. 2 to determine that a state transition has occurred from the state code j to the state code k.

  Next, in step S5-1 of FIG. 6, the transition from the previous state code j of the video recorder device 200 to the value k of the state code D1 is added to the state transition history of FIG. To increase. In the subsequent step S5-2 in FIG. 6, the general possibility of pressing the remote control key in the state after the transition is acquired. Here, the remote control key pressability information E1 is obtained from the remote control key general pressability possibility table for each status code shown in FIG. In the state of this example, the value of the status code D1 is k, and the deletion key 155, the recording key 156, the playback key 134, the G code key 148, and the program navigation key 135 are arranged in descending order of the general pressing possibility value in FIG. It is assumed that the general depressability value of other depressable remote control keys is 10. The pressing possibility value of the remote control key that cannot be pressed is 0.

  In step S5-3, the possibility of pressing the remote control key using the state transition history is added to the remote control key pressability information E1. In the state of this example, from the state transition history of FIG. 9 to the current use history of the video recorder device 200, the number of transitions from the state code k to the next state code is in descending order when the next state code is b. Channel 4 key 121, when the next status code is f, that is, channel 6 key 119, when next status code is c, that is, channel 2 key 115, when next status code is a, that is, channel 10 key 123, next status When the code is e, that is, the delete key 155, when the next status code is h, the recording key 156, when the next status code is g, that is, the reproduction key 134, when the next status code is d, that is, the reservation / confirmation key 153 It is assumed that the number of transitions of the other remote keys that can be pressed is the same 0. In this example, the number of transitions in FIG. 9 is added to the value of each remote control key in the remote control key pressing possibility information E1.

  In the above steps S5-2 to S5-3, the possibility of pressing the remote control key is required, and in the descending order of possibility, the delete key 155 (pressability value 50), the channel 4 key 121 (pressability value 43), Channel 6 key 119 (pressability possibility value 39), channel 2 key 115 (pressability possibility value 38), channel 10 key 123 (pressability possibility value 36), recording key 156 (pressability possibility value 32), play key 134 (Pressability possibility value 30), reservation / confirmation key 153 (pressability possibility value 23), G code key 148 (pressability possibility value 14), and program navigation key 135 (pressability possibility value 12). The pressability value of other remote control keys that can be pressed is 10, and the pressability value of a remote control key that cannot be pressed is 0.

  Next, in step S6 of FIG. 2, the light emission control means emits light by distinguishing the remote control keys that can be pressed by the brightness in order of possibility, and does not emit light to the meaningless remote control keys even if pressed. The light emission control signal F1 is generated.

  Thereafter, the signal transmitted from the video recorder device 200 is actually subjected to light emission processing for each LED attached to the remote control key by the light emission processing means 104 in the remote control transmitter 100. The result is shown in FIG.

  In FIG. 11, skip key 128, skip key 127, slow key 130, search key 131, stop key 132, pause key 133, up direction key 136, left direction key 138, and right direction key 140.

Even if the automatic CM fast-forward key 164 is pressed, it does not emit light as a meaningless key.

  Further, even if the key can be pressed, the power key 111, the HDD key 112, the DVD key 113, the 1-channel key 114, the 3-channel key 116, and the 5-channel key 118 are keys that are unlikely to be pressed. 7-channel key 120, 9-channel key 122, 11-channel key 124, 12-channel key 125, playlist key 137, function selection key 141, return key 143, upward channel movement key 144, A downward channel movement key 145, a volume increase key 146, a volume increase key 147, a display switching key 157, a perfect recording key 159, a recording mode key 160, a screen setting key 161, and an audio key 163 are provided. Emits light with low brightness.

  Next, the reservation / confirmation key 153, the G code key 148, and the program navigation key 135 emit light with higher brightness than the above keys.

  The channel 10 key 123, the recording key 156, and the reproduction key 134 emit light with higher brightness than the above.

  The channel 4 key 121, the channel 6 key 119, and the channel 2 key 115 emit light with higher luminance so as to stand out well.

  The erase key 155 emits light with the highest brightness, and it can be understood at a glance that the remote control user should press the erase key.

  As described above, since a key having a high possibility of pressing emits light with a luminance corresponding to the high possibility of pressing, the user of the remote control transmitter 100 can determine at a glance which key is a key having a high possibility of pressing. Therefore, even those who are not familiar with remote control operation can improve the operability of the remote control.
