Description

  The present invention relates to a remote controller of an electronic device such as a television receiver.

  The television receiver can receive satellite broadcasts and terrestrial digital broadcasts, and can be used to record and play back video and audio of broadcast programs by connecting a hard disk recorder, etc. It is computerized.

  Therefore, when a new type of television receiver is developed and prototyped, it is necessary to check whether there is a bug in the software (program) that realizes the model.

  In this inspection, the inspector performs a predetermined operation according to the evaluation sheet in a predetermined order to check whether there is a bug, and the inspector performs various operations at random. There is a random inspection for checking whether or not there is a bug. Usually, a basic inspection is performed and then a random inspection is further performed.

  If there is a bug, the screen freezes on the display or an image with a color different from the original color is displayed.

  In Patent Document 1 (Japanese Patent Laid-Open No. 2004-56630), when a plurality of persons such as family members watch a program with one television receiver, volume and channel switching are performed on their respective remote controllers. It is shown that each program can be viewed in an environment that is optimal for the user with a simple operation by storing the setting state of the user.

  Patent Document 2 (Japanese Patent Laid-Open No. 4-207694) shows that a video information terminal that receives a remote control signal from a remote controller is provided with a history management means for storing and managing the latest operation history. Yes.

The prior art documents listed above are as follows.
JP 2004-56630 A Japanese Patent Laid-Open No. 4-207694

  However, in the case of the above basic inspection, when there is a bug, it can be seen from the evaluation sheet which operation is performed in which order, but in the case of the above random inspection, When there is a bug, it is ambiguous because it depends on the memory of the inspector which operation is performed in which order, so the same operation is performed to reproduce the bug. , It takes time to do the same order, and may require repeated trials.

  In addition, the appearance of bugs is affected not only by the content and order of operations, but also by the timing of operations. For example, bugs appear when a certain operation is performed in a very short time after a certain operation. However, not only in the case of a random inspection but also in the case of a basic inspection, it is not easy to perform the same operation in the same order and at the same time interval in order to reproduce the bug.

  Therefore, the present invention can accurately determine which operation is performed in which order, and at what time interval without depending on memory, and the same operation is further performed in the same order. Is designed to be easily reproduced at the same time interval.

The remote controller of the present invention is
A key operation unit;
A storage unit for storing a history of a plurality of past operations in the key operation unit;
A display unit for displaying the operation history recorded in the storage unit in time series;
A control unit that detects an operation in the key operation unit, records a history of the operation in the storage unit, and reads out from the storage unit;
It is characterized by providing.

  In the remote controller of the present invention configured as described above, the past operation history is recorded in the storage unit and displayed in time series on the display unit, which operation is performed in which order, Accurate judgment can be made without relying on memory.

  In addition, by recording not only the order and contents of each operation but also the operation time or operation time interval as the operation history, not only which operation was performed in which order, but also at what time interval Can be judged accurately.

  Furthermore, when a reproduction key is provided in the key operation unit and this reproduction key is operated, the control unit performs a series of past operations recorded in the storage unit in the order indicated by the operation history, By generating a series of remote control signals to be reproduced at time intervals and transmitting them from the transmitter of the remote controller, the result is equivalent to performing a series of past operations again. It can be realized by a simple operation.

  As described above, according to the present invention, it is possible to accurately determine which operation is performed in which order, and what time interval is performed without depending on memory. It is easy to reproduce in the same order and at the same time interval.

When various operations such as channel selection by operation and volume adjustment by the operation of the plus direction volume adjustment button 88 or the minus direction volume adjustment button 89 are performed, the CPU 61 of the remote controller 60 performs the contents of the operation for each operation. The time when the operation is performed or the time interval between the previous operation and the previous operation is recorded in the RAM 64 as a history of the operation.

  However, for example, the history of the last 10 operations can be recorded in the RAM 64, and the operation history older than that is erased.

  FIG. 4 shows an example of the operation history recorded in the RAM 64. Operation 1 is the most recent operation, and operation 10 is the oldest operation. Specifically, in this example, the chronological order is as follows.

  (A) In operation 10, at 10:55:25, the power switch 73 is pressed to turn on the television receiver 10 and the terrestrial analog broadcast received immediately before the power is turned off. It is in a state to receive a certain channel.

  (B) Operation 9 switches to channel 8 by pressing the 8th button in channel switching button group 85 at 10:56:03 11 after 37 seconds 35 from operation 10.

  (C) In the operation 8, the two-screen button 91 is pressed to display two screens at 10: 56: 05: 23, 02 seconds 12 after the operation 9.

  (D) In operation 7, at 03:21 after operation 8, at 10: 56: 08: 44, the plus direction volume adjustment button 88 was pressed to increase the volume.

  (E) The operation 6 is switched to the channel 6 by pressing the 6th button in the channel switching button group 85 at 10:56:15 14 after 06 seconds 30 from the operation 7.

  (F) In operation 5, the memo button 95 was pressed at 10: 56: 16: 02 after 00 seconds 48 from operation 6.

  (G) In Operation 4, at 02:53 after Operation 5, at 10: 56: 18: 55, the power switch 73 was pressed to turn off the television receiver 10.

  (H) In Operation 3, at 01:48 after Operation 4, at 10:56:20 43, the power switch 73 was pressed to turn on the television receiver 10.

  (I) In the operation 2, the selection channel 87 which is the channel 6 at the time of the power ON of the operation 3 is changed to the channel 6 by pressing the minus direction channel selection button 87 at 10:56:55 35 seconds 09 after the operation 3. Switched to 8.

  (J) Operation 1 is switched to the operation of the video recording / reproducing apparatus 50 by pressing the operation switching button 75 at 10: 57: 20: 55, 25 seconds 03 after operation 2.

  FIG. 4 shows the operation time and the operation time interval as the operation history, in addition to the operation order and the operation content, but either one of the operation time and the operation time interval may be recorded. For example, when the operation time is recorded, the operation time interval can be calculated from the operation time during reproduction described later.

  As for the operation order, the most recent operation is set to the first, and when the next operation is performed, the operation is set to the first. In the previous operations, the order (number) is incremented by 1, respectively. The history of operations performed is erased from the RAM 64.

  The display screen 67a of the liquid crystal display unit 67 can be configured to display a history of up to 10 operations at that time, but during normal operation, the operation history is recorded in the RAM 64, but is displayed. The past operation history is not displayed on the screen 67a. For example, when the reproduction button 76 is pressed, the past operation history can be displayed on the display screen 67a. In this case, when the reproduction button 76 is pressed again in a state where the operation history is displayed, the past operation may be reproduced as described later.

  As in the random inspection described above, when various operations are performed at random to check whether there is a bug, the operation history is displayed on the display screen 67a of the liquid crystal display unit 67 as described above. When there is a bug, the inspector accurately determines which operation is performed in which order, and at what time interval, without relying on memory. can do.

(2-2. Reproduction of operation: FIG. 5)
When the reproduction button 76 is pressed while the operation history is displayed as shown in FIG. 4, the CPU 61 of the remote controller 60 performs a series of past operations recorded in the RAM 64 in the order shown in the operation history. Furthermore, a series of remote control signals to be reproduced are generated at time intervals and transmitted from the transmission unit 69.

  In this case, all the operations recorded in the RAM 64 can be reproduced, but a user such as an inspector can also specify the reproduction range.

  In the latter case, for example, to reproduce the last four operations from operation 4 to operation 1 with the operation history displayed as shown in FIG. 4, (1) the reproduction button 76 is pressed, and the channel Press button 4 in switching button group 85, or (2) press reproduction button 76, press button 4 in channel switching button group 85, and then press button 1 or (3) reproduction. Press the button 76, press the 1st button in the channel switching button group 85 and then press the 4th button, or (4) press the reproduction button 76, and press the 4th button in the channel switching button group 85. Further, an operation such as pressing the reproduction button 76 is performed.

  If the button in the channel switching button group 85 is not pressed within a predetermined time after the reproduction button 76 is pressed, it is recorded in the RAM 64 at that time as if the reproduction range was not specified. It is configured so that all operations that are present are reproduced.

  FIG. 5 shows an example of the above reproduction process performed by the CPU 61 of the remote controller 60.

  In the reproduction process 100 of this example, with the operation history being displayed on the display screen 67a, it is first determined in step 101 whether or not the reproduction button 76 has been pressed. Determine whether a range has been specified.

  When the reproduction range is not specified, the process proceeds from step 102 to step 103 to generate the same series of remote control signals as when all operations in the operation history are performed in the order and time intervals in the operation history. Then, it transmits from the transmission part 69.

  On the other hand, when the reproduction range is designated, the process proceeds from step 102 to step 104, and the same series of remote control signals as when the operation in the designated range in the operation history is performed in the order and time interval in the operation history are performed. It is generated and transmitted from the transmission unit 69.

  If there is a bug as a result of the above random inspection, as described above, the inspector performs the same operation in the same order in the same order as when the bug appeared, as a simple operation that he / she actually performs. Can be reproduced at time intervals.
