2. Description of the Related Art As broadcast media, FM multiplex broadcast,
Various forms such as RDS and SDARS (satellite digital radio) are known. In such broadcasting media, the number of channels is increasing along with the digitization, and accordingly, the contents of the program information provided for each channel are also diversifying, and the broadcasting contents such as the program name, the program content, and the genre of the program Broadcasting services to which various kinds of information are added are being provided. Then, the user can receive the broadcasting service by selecting a desired channel from various broadcasting media.

Among such multi-channel digital broadcasting services, in addition to broadcasting services that mainly provide "image information" such as ordinary television program information, broadcasting services that mainly provide "text information" such as news and electronic newspapers. Exists.

In a conventional digital broadcast receiver, information about a broadcast service received based on a user selection from various broadcast media is provided to the user via a display (display unit) of the broadcast receiver. ing. At this time, in the case of simultaneously providing a broadcasting service mainly for image information and a broadcasting service mainly for text information, in the conventional technique, as shown in FIG. 6, for example, as shown in FIG. The information (image information, character information) corresponding to each screen is displayed after being divided into.

[0006]

As described above, in the conventional technique, when the broadcast service providing the image information and the broadcast service providing the character information are simultaneously received, the display screen of the digital broadcast receiver is divided into two. Then, the image information and the character information are displayed on each screen (FIG. 6). In this case, if the digital broadcast receiver is for home use, its display screen is relatively large, so no particular problem occurs.

However, if the digital broadcast receiver is a vehicle-mounted type, the display screen is about 8 inches even if it is large, and it is relatively small, so that the display screen is divided and displayed as in the prior art. As a result, the image and the characters become smaller, and the screen becomes difficult for the user to see. That is, there is a problem in that the visibility of the displayed information is reduced.

[0008] In particular, unlike the image information, which can be grasped at a glance like image information, it is necessary to grasp the character information character by character. Therefore, if the character information is small and the amount of character information is large, the content is Becomes even more difficult to recognize.

Further, since two different displays are simultaneously performed on one screen, it is necessary to control the display so that each display is performed, which in turn causes the user interface to be complicated. For this reason, there may arise a problem that the user intends to operate the left screen but actually operates the right screen erroneously, as in the case of the two-screen display in the navigation device.

The present invention was created in view of the above problems in the prior art. When simultaneously providing a broadcasting service mainly for image information and a broadcasting service mainly for text information to a user, each display control is performed. It is an object of the present invention to provide a broadcast information display system that enables easy visual recognition of both image information and character information without complicating the user interface according to the above.

[0011]

In order to solve the above problems of the prior art, according to the present invention, a decoding means for demodulating image / audio data or character data included in a received broadcast wave is provided independently of each other. Firstly, the operation command relating to the selection of the broadcasting service by the user is input respectively.
And second input means, and first and second display means, which are provided independently of each other, and which respectively display information transferred based on user selection, the decoding means, and the first input means.
Input means and a control means operably connected to the second input means, wherein the control means is operable to input an operation command related to selection of a broadcast service for providing image information to the first input means or the first input means. When there is an input from the second input means, the decoding means is controlled to transfer the image information corresponding to the demodulated data to the first display means, and the broadcast service for providing the character information is selected. When the operation command is from the second input means or the first input means,
A broadcast information display system is provided, which controls the decoding means to transfer the character information corresponding to the demodulated data to the second display means.

According to the broadcast information display system of the present invention, when the image information and the character information are simultaneously provided to the user, one screen is divided as in the conventional case (FIG. 6) and each information is displayed on each screen. Since the image information and the character information are displayed on separate screens (first and second display means) instead of being displayed, the image and the character are larger than before, and the image information for the user is It is possible to provide a display that is easy to see for any of the character information.

Further, since each screen of the first and second display means is provided with an independent user interface (first and second input means), an operation independent of the display contents of each screen is provided. (For example, a switching operation of a reception frequency (channel) for selecting a broadcasting service) becomes possible. In other words, each display content of each screen can be changed individually, so that the user interface can be changed as compared with the conventional case where two display contents are controlled on one screen. It is possible to easily change each display content without making it complicated.

Also, preferably, the first display means is
It is desirable to have a screen larger than the screen of the second display means. By making the screen of the first display means relatively large, the visibility of the image information displayed on the screen can be further enhanced.

As another display mode for simultaneously providing image information and character information, when the screen of the first display means is relatively large, the control means sends the character information to the decoding means. Instead of controlling the transfer to the second display means, the character information is controlled to be transferred to the first display means, and the first display means
The transferred image information may be displayed on the large screen, and the transferred character information may be displayed so as to be incorporated in a part of the screen.

In addition, an audio device (A
Various electronic devices such as M / FM broadcast receivers, CD players, etc. and navigation devices are mounted. Most of these electronic devices are unitized and connected to each other by a common signal line (bus) for audio.・ Navigation system can be constructed. In such an audio navigation system, each electronic device is centrally controlled by a device called a "head unit". The head unit is usually provided with an operation unit for centrally managing the states of other electronic devices, and the state of each electronic device (for example, the reception frequency of a broadcast receiver and the CD player). (Track number being played, etc.)
A display unit such as a liquid crystal (LCD) for displaying is incorporated. In recent head units, there are models that use organic electroluminescence (EL) as a display, FM multiplex character broadcast display, and CD-TEXT compatible models that are highly capable of expressing character information.

Therefore, in a preferred embodiment of the present invention, when the broadcast information display system according to the present invention is applied to the on-vehicle audio / navigation system, it serves as a second display means for displaying character information. The display unit (display) of the head unit can be preferably used. In this case, the display unit (display) of the navigation device having a relatively large screen can be used as the first display unit for displaying the image information.

In the digital broadcasting information display system 100 configured as described above, the control unit 11 is a "control unit", the decoding unit 13 is a "decoding unit", and the data type determination unit 15 is a "data type determination unit". The data editing unit 16 is the “data editing unit”, the speaker 23 is the “voice output unit”, the operation unit 32 is the “first input unit”,
The display unit 33 corresponds to the “first display unit”, the operation unit 52 corresponds to the “second input unit”, and the display unit 53 corresponds to the “second display unit”.

In the digital broadcast information display system 100 according to this embodiment, basically as shown in FIG.
When selecting a broadcasting service that provides image / audio information, the operation command V is input from the operation unit 32 of the navigation device 30.
The image information VD input from the decoding unit 13 of the digital broadcast receiver 10 in response to the operation command VARQ by inputting the ARQ is the TV of the navigation device 30 that requested the service of the information. It is displayed on the monitor (display unit 33).

On the other hand, when selecting the broadcasting service for providing the character information, the operation command CRQ is input from the operation unit 52 of the head unit 50, and in response to the operation command CRQ, the decoding unit 13 of the digital broadcast receiver 10 is inputted. The character information CD transferred via the system bus 70 is displayed on the display panel (display unit 53) of the head unit 50 that requested the service of the information.

As described above, according to the present embodiment, when the image information VD and the character information CD are provided to the user at the same time, each information is displayed on a separate screen (display units 33 and 53). Compared to the case where one screen is divided and information is displayed on each screen as in the conventional case (FIG. 6), the image and characters are larger, and the user can easily see. This makes it possible to improve the visibility of the displayed information.

Since the screens of the display units 33 and 53 are provided with independent user interfaces (operation units 32 and 52), the display contents of the respective screens can be operated independently, for example, the reception frequency ( It is possible to perform switching operation of channels) and scanning operation. That is, since the display content of each screen can be changed individually, the user interface is more complicated than in the conventional case where the control is performed for two display contents on one screen. It is possible to easily change each display content without doing so.

When the power supply of the TV monitor (display unit 33) of the navigation device 30 is off, the display on the TV monitor is turned on / off in response to the input of the parking brake detection signal or the vehicle speed pulse signal. Or if the user is using a navigation system (that is, the TV monitor is displaying information related to the original navigation and is in a state where it cannot be used to display other information). , The user displays the character information C on the display panel (display unit 53) of the head unit 50.
It is possible to see D.

In the above-described embodiment, the operation command VARQ for requesting the image / audio information service and the display of the image information VD based on the operation command VARQ are input through the operation unit 32 and the display unit 33 of the navigation device 30, while The operation command CRQ for requesting the character information service and the display of the character information CD based on the operation command CRQ are described as an example through the operation unit 52 and the display unit 53 of the head unit 50, but the gist of the present invention (basic Image information VD
Is displayed on the TV monitor (display unit 33), and the character information CD is displayed on the display panel (display unit 53) so that the display can be easily viewed. It goes without saying that it is not always necessary to input the commands VARQ and CRQ from the operation units 32 and 52, respectively.

Contrary to this input form, an operation command VARQ related to image / voice information is input from the operation unit 52 of the head unit 50, and an operation command CRQ related to character information is input to the operation unit 32 of the navigation device 30. You may start from.

Further, in the above-described embodiment, as shown in FIG. 4, the case where the image information VD and the character information CD are displayed on separate screens (display units 33 and 53) to improve the visibility of each information is described. As I explained, the image information VD
The form in which the user and the character information CD are simultaneously provided is not limited to this, and other display forms are also conceivable.

For example, when the screen of the TV monitor (display unit 33) of the navigation device 30 is relatively large,
The text information CD may be displayed together with the image information VD on the screen of the TV monitor. An example thereof is shown in FIG.

In this case, the image information VD and the character information CD output from the decoding unit 13 under the control of the control unit 11 in the digital broadcast receiver 10 are output to the system bus 70, and each information is sent to the navigation device. It is transferred to the TV monitor (display unit 33a) via the communication control unit 41 and the navigation control unit 31 of 30. TV
The monitor (display unit 33a) includes the navigation control unit 31.
Thus, the transferred image information VD is displayed on the large screen, and the character information CD is displayed so as to be incorporated in a part of the screen (the lower part of the screen in the illustrated example).

In the above embodiment, the case where the digital broadcast information display system 100 is applied to the vehicle-mounted audio navigation system has been described, but the broadcast information display system according to the present invention is not limited to the vehicle-mounted one. Is. In short, means for decoding image data, character data, etc. included in the received broadcast wave, means for displaying image information and character information separately, independent operation for each display content (user interface)
The present invention can be applied to any system as long as it is a system equipped with an input unit capable of performing the above, and a unit controlling each of these units.

Further, in the above-mentioned embodiment, the case of displaying the information related to the digital broadcasting has been described as an example.
As is clear from the gist of the present invention, the information to be displayed is not limited to digital broadcast information, and may be analog broadcast information, for example.

[0053]

As described above, according to the present invention, when the image information and the character information are simultaneously provided to the user in the broadcast information display system, the image information and the character information are basically displayed on separate display screens. In addition, by providing means capable of performing an independent operation for each display content, a display that is easy for the user to visually recognize both image information and character information is provided without complicating the user interface. It becomes possible to do.
