  According to the technique described in Patent Document 1, a remote control signal receiving unit that receives remote control signals of different formats respectively transmitted from a plurality of remote control transmitters, and each of the remote control signals transmitted from each remote control transmitter. The memory unit that stores information related to the format and the format of the remote control signal that is first received by the remote control signal receiver after the power is first turned on are determined based on the comparison with the stored information in the memory unit. And a control unit having a function of setting so that only a remote control signal of the resulting format can be received thereafter. That is, only one remote control signal of a plurality of types of remote control transmitters can be selectively received.

  However, there is no description about the display contents and functions corresponding to the remote controller identified by the receiving device, and in Patent Document 1, the receiving device causes the user to display and operate according to the characteristics of a plurality of remote controllers. There was a problem that it was not possible to cope with improvement of convenience.

  Accordingly, the present invention has been made to solve the above-described problems. A display device that identifies one of a plurality of remote controllers and performs display and operation in accordance with the characteristics of the identified remote controller, and Provide a display method.

  In order to solve the above-described problem, the present invention provides an identification device for receiving a remote control code signal transmitted from the remote control and identifying which remote control is based on the remote control code signal in a display device corresponding to a plurality of remote controls. And a holding unit that holds screen information corresponding to the plurality of remote controllers in advance, and the holding unit holds the screen information corresponding to the remote control identified by the identification unit. And a control unit for displaying the screen information.

  According to the present invention, the convenience of the user can be improved because the device displays and operates in accordance with the characteristics of a plurality of remote controllers. That is, if there is a simple remote controller in addition to the normal remote controller, the basic functions of the device can be enjoyed even if the device is not good at operation. In addition, if there is a remote controller specialized for a specific function (for example, an edit remote controller), a detailed menu screen of the function can be displayed, which makes it easy to use the function.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a remote controller (normal remote controller) that supports all functions. FIG. 2 is a diagram showing a remote controller (simple remote controller) that supports only functions frequently used by the user.

  The remote controllers 100 and 200 shown in FIGS. 1 and 2 are remote controllers that are compatible with a DVD recorder. The normal remote controller 100 in FIG. 1 includes a power button 50 for turning on / off the power supply on the apparatus side, a navigation button 52 for viewing a recorded title list, a navigation button 54 for recording a title to be recorded, A channel button 55 for changing a channel, a start menu button 56 for calling a menu, a playback button 57 for playing back a title, a stop button 58 for stopping a title being played back, and a recording button for recording a title 59 etc., and other function buttons are also fully equipped. That is, it is a normal remote controller that supports all functions such as editing.

  2 is a power button 60 for turning on / off the apparatus, a start menu button 62 for calling a menu, a playback button 64 for playing a title, a title being played, and the like. A stop button 66 for stopping the recording, a recording button 68 for recording the title, and the like, but other function buttons are omitted as much as possible. In other words, it is a simple remote control with only basic buttons for recording / viewing.

By attaching a plurality of remote controls in this way, various users can use the DVD recorder without feeling stressed.
However, the user interface screen such as the menu screen is the same whether the simple remote controller 200 or the normal remote controller 100 is used. Therefore, a user who is unfamiliar with the DVD recorder may still receive an impression that it is complicated (not easy).

  In the present invention, the target device performs screen display and operation corresponding to each remote controller. Hereinafter, the present invention will be described by taking a DVD recorder having two remote controllers as an example.

  Normally, remote control codes are assigned to the buttons of the remote control, but different remote control codes are assigned to the two remote controls (FIGS. 1 and 2) so that they can be identified. At this time, a code different from that shown in FIG. 1 may be assigned to all the buttons of the simple remote controller 200 shown in FIG. 2, or a different code may be assigned only to a specific button such as a power source.

  When codes different from those in FIG. 1 are assigned to all buttons of the simple remote controller 200 in FIG. 2, the DVD recorder can identify which remote controller the user is using regardless of which button is pressed. Also, if a different code is assigned only to a specific button such as a power supply, for example, if a different code is assigned to the power button, it can be identified that the user is using the remote control by pressing the power button. Become.

  When the DVD recorder identifies any remote controller, the menu screen, operation, etc. displayed on the screen correspond to that remote controller. If the normal remote controller 100 as shown in FIG. 1 is identified, a start menu screen 80 corresponding to all functions as shown in FIG. 3 is displayed, and if the simple remote controller 200 as shown in FIG. A menu screen 85 corresponding to only frequently used functions as shown in FIG. In the example of FIG. 4, the editing items and setting menu are not displayed as compared with FIG.

  As described above, in the case of a device having a plurality of remote controllers shown in FIGS. 1 and 2, when the simple remote controller 200 shown in FIG. 2 is used, a basic operation (simple function) of recording / viewing corresponding to the simple remote controller 200 is performed. Since only the screen is displayed, the desired item can be easily selected. In addition, when the normal remote controller 100 of FIG. 1 is used, a screen display corresponding to all functions is provided, so that more complicated operations such as editing / dubbing are possible.

Next, an example of the signal format of the remote controller will be described.
FIG. 5 is a diagram showing an infrared remote control signal, in which a reader code 31 indicating that the remote control signal starts, a custom code 32 required to identify each electronic device, and data indicating a control command to the selected electronic device A code 33 is used. The modulation frequency, bit 0, and bit 1 timing definitions of each electronic device are shown.

  Specifically, since the leader code 31 is in the on state for a period of 9 ms and then is in the off state for a period of 4.5 ms, this portion has a waveform (time) different from that of the subsequent custom code 32 and data code 33. Since it is greatly different, it can be easily identified as a leader code. The custom code 32 has a 16-bit length and is divided into two 8-bit parts, and is a code for assigning each company and electronic devices of the company. For example, DVD of T company, VTR of S company, VTR of N company, CS tuner of F company are represented by codes. The data code 33 is a code for assigning a certain function key (for example, reproduction, recording, etc.) among the electronic devices of each company assigned by the custom code 32.

  FIG. 6 shows a remote control code table assigned to the T company. The custom codes 32 assigned to the T company are “01AB” and “01CD”. Here, two device codes are assigned (a plurality of device codes), both of which are DVD recorders, one for normal remote control 100 and the other for simple remote control 200. The data code 33 indicates assignment of a function key. For example, “13” for playback, “14” for recording, “15” for channel +, “16” for channel−, and the like. It has become.

Therefore, when the playback button is pressed using the normal remote controller 100 of the DVD recorder of company T, a waveform representing “01AB13” is transmitted from the remote controller.
Next, FIG. 7 shows a block diagram of a schematic configuration of the display device according to the embodiment of the present invention.
The display device shown in this embodiment can handle both DVD-RAM and hard disk as recording media. FIG. 7 includes a DVD-RAM drive device 8 and a hard disk drive device 9. The DVD-RAM drive device 8 can read / write from / to a DVD-RAM, which is an optical disk medium, and can access several types of DVD-RAM. The hard disk drive 9 includes a hard disk medium as a recording medium.

  These two recording media drive devices are devices that include all processes such as rotation control systems, laser drive system circuits, optical system circuits, and error correction of data recorded on media.

  The basic operation of this display device will be described. A video signal and an audio signal are input from the video input unit 1 and the audio input unit 2. The video signal is converted from an analog signal to a digital signal by an analog / digital (A / D) conversion circuit 3, and the audio signal is converted by an A / D conversion circuit 4.

  The converted video digital signal is encoded into MPEG2 compressed video data by the encoder 5, and the audio digital signal is encoded into compressed audio data such as AC3 or MPEG. Further, these compressed video and audio data are further converted into the MPEG2 system layer by the encoder 5.

  The signal from the encoder 5 is converted in format by the formatter 6 and converted into a format defined in the DVD recording standard (DVD-RAM, DVD-RW, etc.).

  The format-converted signal is converted into recording data including a command conforming to the DVD-RAM drive 8 or the hard disk drive 9 by the data processing unit 7 and recorded on the DVD-RAM or the hard disk. The data processing unit 7 is mainly occupied by a buffer circuit.

  Here, in addition to the format-converted data, this apparatus creates reproduction management information by the MPU unit 18 and records it on a DVD-RAM or hard disk via the data processing unit 7.

  Information recorded on the DVD-RAM can also be recorded on the hard disk via the data processing unit 7. On the other hand, it is also possible to record information on the hard disk in the DVD-RAM. However, it is a condition that the DVD-RAM and the hard disk have the same format.

  It is also possible to edit a plurality of programs recorded on a DVD-RAM or a hard disk. In that case, it is possible to easily delete a plurality of programs, edit and reproduce, etc. by a method corresponding to the DVD-VR format. In that case, the MPU unit 18 corrects the management information and further copies, moves, and deletes the formatted signal through the data processing unit 7.

  When the recorded data is reproduced, data formatted in the data processing unit 7 is input from a DVD-RAM or a hard disk, and the output of the data processing unit 7 is input to the decoder 10. The decoder 10 decodes the DVD format signal.

  The decoder 10 mainly has a part for separating the formatted data and a part for decoding the separated compressed video data and audio data. Video data is subjected to decoding processing by the MPEG2 system, and audio data is subjected to decoding processing such as MPEG and AC3. The decoded video data and audio data are sent to selectors 11A and 11B, respectively. The selectors 11A and 11B switch between when the input signal is sent to the digital / analog D / A conversion circuits 12 and 13 as it is and when the recorded information is reproduced. The MPU unit 18 performs switching control. The video data output from the selector 11A is converted into an analog signal by the D / A conversion circuit 12, and supplied to the monitor 14. The audio data output from the selector 11B is converted into an analog signal by the D / A conversion circuit 13 and supplied to the speaker 15.

  In addition to the above, the MPU unit 18 receives a user's remote control code from the key input unit 16 (for example, a remote controller) and controls the display operation of the display device. In the present invention, after the remote control code from the key input unit 16 is identified by the remote control code identification unit 17a and the remote control is specified, a display suitable for the feature of the remote control is performed. Therefore, how to display will be described with reference to FIG. FIG. 8 is a flowchart of a display method when the display device is used. Here, description will be made assuming that the display device is compatible with the normal remote controller 100 of FIG. 1 and the simple remote controller 200 of FIG.

  First, a user usually tries to reproduce the title of a DVD on which the remote controller 100 is operated. When the user presses the playback button of the remote controller 100, a remote control code assigned in advance from the normal remote controller 100 is transmitted to the display device. In the display device, the remote control code transmitted is received by the remote control code identification unit 17a, and the remote control is identified (ST1, 3).

  Specifically, a remote control code table as shown in FIG. 6 is stored in the remote control code identification unit 17a, and the remote control code identification unit 17a compares the received remote control code with the stored remote control code table. Identify which remote control. Here, for example, “01AB13” is received, so the remote control code identification unit 17a identifies “reproduction” of the normal remote control 100 of the DVD recorder of company T from the code table. When the MPU 17 is identified as the normal remote controller 100, the MPU 17 calls screen information for the normal remote controller 100 (for example, the start menu screen shown in FIG. 3) stored in the ROM 17b (ST5). Then, the screen information is displayed on the monitor 14 via the decoder 10 (ST7).

  In step ST3, when the MPU 17 identifies that it is not the normal remote controller 100 but the simple remote controller 200, the MPU 17 calls screen information (for example, the start menu screen shown in FIG. 4) stored in the ROM 17b (ST9). ). Then, the screen information is displayed on the monitor 14 via the decoder 10 (ST11).

  As described above, the convenience of the user can be improved when the device displays and operates in accordance with the characteristics of a plurality of remote controllers. In other words, if there is a simple remote controller in addition to the normal remote controller, you can enjoy the basic functions of the device even if you are not good at operating the device. In addition, if there is a remote controller specialized for a specific function (for example, an edit remote controller), a detailed menu screen of the function can be displayed, which makes it easy to use the function.

  In this description, the normal remote controller and the simple remote controller have been described as examples. However, a remote controller specialized for a certain function such as a reservation remote controller or an editing remote controller may be used. The remote controller may be customized for individual use (reflecting the program preference). Yes, it can be a personal remote control.

  In addition, this invention is not limited to the said embodiment, In the implementation stage, it can change variously in the range which does not deviate from the summary.
