Description

  The present invention relates to a broadcast receiver such as an HD (High Definition) radio, a control method for a broadcast receiver applied to the radio and the like, and a program broadcast receiver, and more particularly to a broadcast receiver with an improved user interface. is there.

  The IBOC (In Band On Channel) transmission format, which is a radio transmission format, is a hybrid broadcast that includes one analog broadcast portion and one digital broadcast portion as broadcast modes (hereinafter simply referred to as “IBOC broadcast”). Real-time performance is important, such as full digital broadcasting with a single digital broadcasting part, Tomorrow Radio broadcasting (hereinafter referred to as “TR broadcasting”) including one analog broadcasting part and a plurality of digital broadcasting parts, and baseball broadcasting. There is a non-delay broadcast that preferentially outputs analog audio with respect to broadcast content. The IBOC broadcast station may change the broadcast mode as appropriate according to the contents of the broadcast program.

  In each broadcast mode of the IBOC transmission format, functions unique to the broadcast mode may exist. For example, the channel switching function is an effective function in TR broadcasting including a plurality of digital broadcasting parts of a main channel and one or more sub-channels, but is an IBOC broadcasting including only one digital broadcasting part. Then, it is a function that is disabled.

  In the conventional HD radio, the user switches the screen that presents the broadcast mode information or supports each broadcast mode in order to know which broadcast mode is the IBOC transmission format as the currently selected received broadcast. It is necessary to visually check the lighting of the attached indicator, and based on the broadcast mode known in this way, the operation members that instruct execution of the currently effective function are determined by themselves, and they are operated based on the determination. It is very complicated for the user to switch to the broadcast mode information presentation screen. In addition, the area where indicators such as in-vehicle displays are provided is limited, and if indicators are provided in the number corresponding to the number of broadcast modes, the size of each indicator is reduced and it is difficult for the user to visually recognize each indicator.

  Patent Document 1 relates to the digital broadcast receivers of FIGS. 1, 2, 4 and 6 in which the backlight color is changed for each reception medium (BS broadcast, terrestrial digital broadcast, digital CATV broadcast, etc.). Is disclosed. Further, in relation to the digital broadcast receiver shown in FIG. 7, backlights are categorized according to the broadcast type of each reception medium (eg, TV broadcast, audio broadcast and data broadcast) and by video format (eg, high-definition broadcast and standard broadcast). Also disclosed is changing the color. The reception media substantially corresponds to the transmission format, and the broadcast type and the video format substantially correspond to the broadcast mode. In the broadcast receiver of Patent Document 1, the user can recognize the information of the transmission format and the broadcast mode only by visually recognizing the backlight color instead of switching the screen or visually recognizing the indicator. It becomes easy.

Patent Document 2 discloses that the genre of a program being received is detected and the font and text color of the subtitle are changed according to the genre. By fixing the font and text color of the subtitles for each genre, the sense of unity between the program contents and the subtitles is increased, and the impression of the user is increased.
JP 2001-275051 A JP 2002-271712 A

  Patent Document 1 only discloses that the user recognizes the transmission format or the broadcast mode by the backlight color. Patent Document 2 only discloses matching the font or color of subtitles with the genre of the program being output.

  In a broadcast receiver such as an HD radio, a predetermined function is effective for a certain broadcast mode, but may be invalid in another broadcast mode. Correspondingly, a mechanical operation member assigned to a user operation or menu item display for instructing a predetermined function in a certain broadcast mode and a menu item on the display are displayed in a different broadcast mode. Operation or selection may be invalidated. In this case, the user needs to know the broadcast mode of the currently selected received broadcast, and determines which operation member or menu item is effective for the user operation or selection in the broadcast mode based on the memory. A user operation or selection must be performed on an effective operation member or menu item, which is complicated. Patent Documents 1 and 2 do not suggest a technique for dealing with this.

  In addition, when the selected received broadcast includes an analog broadcast part and a digital broadcast part, if the text can be extracted from both the analog broadcast part and the digital broadcast part, it is extracted and displayed to the user. It may not be known whether the text being extracted is extracted from the analog broadcast part or the digital broadcast part. For example, in the TR broadcast, the audio being output is extracted from the analog broadcast part, the text being displayed on the display is extracted from the digital broadcast part, and the user receives the selected received broadcast is the TR broadcast, In some cases, the user is not aware that the audio being output and the text being displayed are different sources, and an unnecessary user operation is performed. Patent documents 1 and 2 do not suggest a technique for dealing with this.

  An object of the present invention is to provide a broadcast receiver, a control method for a broadcast receiver, and a program that enable a user to efficiently identify an operation unit or menu item effective in a currently selected received broadcast.

  Another object of the present invention is that when the selected received broadcast includes an analog broadcast part and a digital broadcast part, the text extracted and displayed to the user is either the analog broadcast part or the digital broadcast part. It is to provide a broadcast receiver, a control method for a broadcast receiver, and a program capable of efficiently informing whether it is extracted from the program.

  In the broadcast receiver, the broadcast receiver control method, and the program of the present invention, the broadcast mode of the selected received broadcast is detected, and the operation unit for instructing the execution of the function effective in the broadcast mode is used as the valid operation unit. A broadcast mode color is detected as a color that is detected and associated with the broadcast mode. At least a part of the background portion of the display, typically the entire background portion, is set as the broadcast mode color, and the broadcast mode color or a related color (eg, a complementary color of the broadcast mode color) is associated with the effective operation unit. It is done.

  In another broadcast receiver, control method for broadcast receiver, and program of the present invention, a broadcast mode of a reception broadcast being selected is detected, and a user can select a plurality of menu items to be selected by the user in the broadcast mode. A menu item that is valid is detected as a valid menu item, and a broadcast mode color as a color associated with the broadcast mode is detected. Then, at least part of the background portion of the display, typically the entire background portion, is set to the broadcast mode color, and the broadcast mode color is typically associated with the effective menu item as the background color of the effective menu item. Is displayed.

  Another broadcast receiver, broadcast receiver control method and program of the present invention are the broadcast receiver, broadcast receiver control method and program of the present invention, or another broadcast receiver and broadcast receiver described above. The following technical items are added to the control method and program. That is, text is extracted from a received broadcast that is selected and includes an analog broadcast portion and a digital broadcast portion, and the extracted text is displayed on the display. Then, it is determined whether the text source is an analog broadcast portion or a digital broadcast portion of the received broadcast, and a color associated with the source is detected as a source color. The source color is typically displayed in association with the text as the background color for the text being displayed on the display.

  According to the present invention, in the broadcast mode of the selected received broadcast, an operation unit effective for user operation or a menu item effective for selection is associated with at least a portion of the background portion of the display by the broadcast mode color or its related color. Therefore, the user can efficiently grasp an effective operation unit or menu item.

  According to another broadcast receiver, broadcast receiver control method, and program of the present invention, the text being displayed is associated with the analog broadcast part or digital broadcast part from which the text is extracted by color, so that the user Efficiently grasp the source of extraction.

  FIG. 1 is a configuration diagram of the HD radio 10. The HD radio 10 supports reception in the IBOC transmission mode. The broadcast mode of the radio broadcast of the analog FM broadcast alone may be handled as an example of the broadcast mode of the IBOC transmission mode in the output processing of the broadcast content of the radio broadcast, that is, the broadcast mode of the IBOC transmission mode. Among them, the HD radio 10 that can be handled as a broadcast mode that does not include a digital broadcast, and that supports reception of the IBOC transmission mode, can output audio of an analog FM broadcast alone as well as a radio broadcast in the IBOC transmission mode. It has become. The HD radio 10 is also equipped with an AM tuner, and can output the broadcast content of AM analog broadcasts by switching the transmission mode of the user. The HD radio 10 is not limited to a mobile type mounted on a car or carried by a person, for example, and may be a type that is not portable and can be installed in a house.

  The input device 11 is operated by a user and sends user operation information to the main controller 12. The tuner 13 selects a corresponding received broadcast based on the channel selection information from the main controller 12 and outputs an intermediate frequency signal of the received broadcast to the analog / digital demodulator 14. The analog / digital demodulator 14 demodulates the intermediate frequency signal from the tuner 13, converts the demodulated signal into a digital signal, performs predetermined decoding, and extracts the predetermined frequency extracted based on the audio selection information from the main controller 12. Are sent to the voice processing / output device 15. The analog / digital demodulator 14 also sends various extracted data to the main controller 12. The analog / digital demodulator 14 includes, for example, a speaker, and the audio processing / output device 15 outputs audio related to the audio signal from the analog / digital demodulator 14 at a volume adjusted by the user.

  The display control unit 16 controls the display content and display mode on the display device 17 based on the control information and display content information from the main controller 12. The backlight control unit 18 controls the backlight light emitting unit 19 based on control information from the main controller 12. Here, what is appropriately displayed as a video key in the touch panel and touched by the user at the time of selection is defined as a “soft key”. The mechanical operation member is an operation member that is operated by being physically displaced by a user with respect to a soft key. The backlight light emitting unit 19 is disposed on the back side of each mechanical operation member, and the light emission color of the backlight light emitting unit 19 is at least partially transparent each disposed on the back side. It passes through the operation member and is visually recognized by the user as the color of each operation member.

  FIG. 2 is a front view showing the state of the HD radio 30 when the broadcast mode of the received broadcast selected by the user is IBOC broadcast. Note that, as described above, the IBOC broadcast refers to a hybrid broadcast that includes one analog broadcast portion and one digital broadcast portion in the IBOC transmission format. The HD radio 30 is an embodiment of the HD radio 10 of FIG. 1. The input device 11 in the HD radio 10 is embodied as a rectangular key 34 and a circular key 35 in the HD radio 30. The display device 17 is a color LCD 33 in the HD radio 30.

  Broadcast modes that can be received by HD radio as of 2005 are analog broadcast only, IBOC broadcast, full digital broadcast, non-delay broadcast, and TR broadcast. Therefore, HD radio will be described in accordance with this. However, in the future, new broadcasting modes may be added as new services such as traffic information and data broadcasting are added. The broadcast mode in the present invention does not exclude broadcast modes added in the future.

  In the HD radio 30, a different color is set for each broadcast mode, or for each analog broadcast portion and digital broadcast portion signal within a predetermined broadcast mode. For example, the set colors for the analog broadcast part and the digital broadcast part in each IBOC broadcast mode or in a predetermined broadcast mode are as follows.

(A1) Analog broadcast part when one received broadcast is one analog broadcast, or analog broadcast part of IBOC broadcast and TR broadcast: White (a2) Digital broadcast part when IBOC broadcast: Blue (a3) Full digital broadcasting: Yellow (a4) Non-Delay broadcasting: Light blue (a5) Digital broadcasting part in the case of TR broadcasting: Green

  In the drawing, since the color cannot be expressed, the color is expressed in the form of the line in each area in each figure. The relationship between the line entry mode and the color is as follows.

(B1) Vertical parallel lines (FIGS. 2 and 4): Blue (b2) Horizontal parallel lines (FIG. 3): Green (b3) Diagonal parallel lines rising upward (FIG. 4): Light blue

  For convenience of explanation of the configuration of the HD radio 30, the left and right of the HD radio 30 refer to the left and right of the HD radio 30 as viewed from the front. The front panel 31 is disposed in front of the HD radio 30, and the volume adjusting member 32 is disposed at the left end of the front panel 31, and is rotated by the user when the volume of the speaker is increased or decreased. The color LCD 33 occupies a range from the right end of the volume adjustment member 32 to the vicinity of the right end of the front panel 31 in the left-right direction on the front panel 31 and displays predetermined information as text. A plurality (seven in the figure) of rectangular keys 34 are arranged in a horizontal row below the color LCD 33 and are pressed by the user when various user instructions are given. A plurality (three in the figure) of circular keys 35 are arranged in a horizontal row to the right of the row of rectangular keys 34 below the color LCD 33. The rectangular key 34 and the circular key 35 are included in the concept of the mechanical operation member described above.

  The user instruction for the HD radio 30 is associated with each rectangular key 34 and each circular key 35, and one rectangular key 34 or circular key 35 may be associated with a plurality of user instructions. One rectangular key 34 or circular key 35 may be associated with a common user instruction regardless of the broadcast mode, or may be associated with a different user instruction for each broadcast mode. For example, of the three circular keys 35, the rightmost circular key 35 is a channel switching key. When the broadcast mode is TR broadcast, since the TR broadcast includes a plurality of digital broadcast portions, the channel can be switched and the pressing operation of the circular key 35 at the right end is effective. On the other hand, when the broadcast mode is IBOC broadcast, since the IBOC broadcast includes only one digital broadcast part, it is difficult to switch channels, and the right-side circular key 35 is not pressed. become.

  The HD radio 30 in FIG. 2 has selected the reception broadcast of the IBOC transmission format, the broadcast mode of the reception broadcast is IBOC broadcast, and the audio related to the digital broadcast portion of the IBOC broadcast is being output. ing. Therefore, the channel switching function is invalid. Note that general IBOC broadcasting is a simultaneous broadcasting between an analog broadcasting part and a digital broadcasting part, and switching between the analog broadcasting part and the digital broadcasting part in the HD radio 30 may be manually performed by a user. Normally, the digital broadcast part is preferentially selected by the AUTO switching function, and the analog broadcast part is selected only when the electric field strength is less than a predetermined level.

  On the color LCD 33 of the HD radio 30, “FM1” is set as the preset key number in which the selected received broadcast is set, “WXYZ-FM” is used as the broadcast station name of the received broadcast, and “ "Let it be" and "Beatles" are displayed as the artist name of the music. In FIG. 2, since the broadcast mode of the currently selected reception broadcast is IBOC broadcast, the background color (= display color) of the color LCD 33 is blue. Further, as described above, since channel switching is invalid in IBOC broadcasting, user operation is invalid for the circular key 35 at the right end, which is an operation member for channel switching. Accordingly, the backlight of the rightmost circular key 35 is turned off, and the circular key 35 other than the rightmost circular key 35 and all the rectangular keys 34 (the circular key 35 and the rectangular key 34 are operated by the user). The backlight of) is blue. The user performs a user operation on the valid rectangular key 34 and the circular key 35 with a mark that the predetermined rectangular key 34 and the circular key 35 have the same color as the display color. Further, the user recognizes that the user operation is invalid even if the circular key 35 at the right end is operated.

  FIG. 3 is a front view showing the state of the HD radio 30 when the broadcast mode of the received broadcast selected by the user is TR broadcast. Since the selected broadcast mode of the received broadcast is TR broadcast, “TR” is displayed as an indicator on the right end of the color LCD 33, and the background color (= display color) of the color LCD 33 is green. Since the TR broadcast includes a plurality of digital broadcast portions, channel switching for switching the digital broadcast portions is effective. Therefore, the user operation of the right end circular key 35 is also effective. As a result, the backlights of all the circular keys 35 and all the rectangular keys 34 included in the rightmost circular key 35 turn green. The user operates the user with respect to the effective rectangular key 34 and the circular key 35 by setting that the backlight of the predetermined rectangular key 34 and the circular key 35 is the same color as the display color.

  As the vehicle equipped with the HD radio 30 moves, the electric field strength of the currently selected received broadcast may decrease and become less than the predetermined level L1. Further, if the electric field strength is weakened, it is difficult to output not only the digital broadcast portion but also the analog broadcast portion, but if the electric field strength is slightly lower than L1, the audio of the digital broadcast portion cannot be output. Part of the audio can be output. In the case where the AUTO switching function is set in the HD radio 30, when the electric field strength of the selected received broadcast is less than the predetermined level L1, automatic switching from the digital broadcast portion to the analog broadcast portion is performed. Accordingly, the display color of the color LCD 33 becomes white, and the remaining rectangular keys 34 and circular keys 35 except those in which the user operation is disabled in the analog broadcast part are changed from green to their backlights. The white color associated with the analog broadcast portion is switched.

  FIG. 4 is a front view showing a state of the HD radio 30 when the broadcast mode of the received broadcast selected by the user is Non-Delay broadcast. When the broadcast mode is Non-Delay broadcast, the HD radio 30 outputs analog broadcast audio. However, the non-delay broadcast digital broadcast portion includes text that can be displayed and output, and the text may be extracted from the digital broadcast portion and displayed.

  The color LCD 33 is divided into a text display area for displaying the text “Let it be / Beats” and other display color areas. In the HD radio 30 of FIGS. 3 and 4, text is extracted from the digital broadcast portion of the IBOC broadcast and the TR broadcast, and both the text display area and the display color area are blue and green as display colors. However, in Non-Delay broadcasting, since the audio output from the speaker is extracted from the analog broadcasting part, and the text is extracted from the digital broadcasting part, the text display area and the display color area are Each color is blue (blue is a color associated with IBOC broadcasting) and light blue (non-delay broadcasting) meaning a digital broadcasting portion. Accordingly, the user recognizes that the source of the text currently being displayed is different from the source of the audio output currently being output, and performs a user operation or the like that copes with the recognition. Further, in non-delay broadcasting, since the digital broadcasting part between the main channel and the sub channel is not switched, the circular key 35 at the right end has its backlight turned off.

  FIG. 5 is a front view of the HD radio 50 equipped with the color touch panel 53. The color touch panel 53 also serves as a display of a navigation device equipped in the automobile together with the HD radio 50, and also serves as a user operation unit as a touch panel. The HD radio 50 is an example of the HD radio 10 in FIG. 1, and the color touch panel 53 is an example of the display device 17 and the input device 11 of the HD radio 10. The color touch panel 53 occupies almost the entire surface of the front panel 51 except for its lower side portion. A volume adjustment member 52, a rectangular key 54, a circular key 55, and a screen switching key 56 are arranged in a horizontal row on the lower side portion of the front panel 51. The volume adjustment member 52 is disposed at the right end, and the three rectangular keys 54 and the two circular keys 55 are disposed in the left half. The pair of screen switching keys 56 is disposed between the rightmost circular key 55 and the volume adjustment member 52. The volume adjustment member 52, the rectangular key 54, the circular key 55, and the screen switching key 56 are mechanical operation members.

  The color touch panel 53 in FIG. 5 includes a main screen 60 and a menu screen 61. The main screen 60 displays text information regarding the music currently being output. The menu screen 61 includes “Equalizer setting”, “Reception mode switching”, “Channel switching”, and “Seek mode switching” as menu items, and is popped up on the front side of the main screen 60. The menu screen 61 appears when the user operates a predetermined operation member or touches a predetermined touch portion in the color touch panel 53.

  It is assumed that the broadcast mode of the reception broadcast currently selected by the HD radio 50 in FIG. 5 is TR broadcast. Accordingly, the background color (display color) for the text on the main screen 60 is green, and the rectangular keys 54 and the circular keys 55 (all rectangular keys 54 in the example of FIG. 5) as keys for which the user operation is valid. And the circular key 55 is enabled.) The backlight is green. The left and right screen switching keys 56 are pressed by the user when returning to the previously displayed screen relative to the currently displayed screen or when proceeding to the next screen to be displayed. Since the screen switching key 56 cannot be used as a user operation when the selected received broadcast is a TR broadcast, its backlight is currently turned off. Further, among the menu items on the menu screen 61, the background color for the text in the display area of “channel switching” dedicated to TR broadcasting as the current broadcasting mode is also set to green as the color associated with the TR broadcasting. “Equalizer setting”, “Reception mode switching” and “Seek mode switching” as other menu items are effective not only when the broadcasting mode is IBOC broadcasting but also for all broadcasting modes. The color associated with all modes is used as the background color for the text.

  In the HD radio, the reception broadcast of the analog broadcast alone is selected and the audio can be output. Therefore, not only the broadcast mode in the IBOC transmission format but also the broadcast mode of the analog broadcast alone (for example, RDS (or RBDS. RDS: Radio Data System (RBDS: Radio Broadcast Data System), mono / stereo, etc.) may be equipped with predetermined functions. In the present invention, it is possible to set the color corresponding to each broadcast mode in the reception broadcast of the analog broadcast alone, similarly to the broadcast mode of the IBOC transmission format for each broadcast mode in the reception broadcast of the analog broadcast alone. It is. For example, orange, white, and pink are assigned to broadcast modes of RDS (or RBDS), analog stereo FM broadcast, and analog mono FM broadcast, respectively. It should be noted that the color associated with each broadcast mode of the reception broadcast of the analog broadcast alone can be changed according to the preference of the receiver and the user, like the broadcast mode color associated with each broadcast mode of the IBOC transmission format. In addition, as a function different for each broadcast mode in reception broadcast of analog broadcast alone, a stereo blending function by multipath when the broadcast mode is FM broadcast such as RDS (or RBDS) (stereo broadcast when noise increases due to multipath) There is an on / off setting of a function that reduces noise by blending. The on / off setting is not present when the broadcast mode is AM.

  Thus, the display color of the HD radio 30 (background color of the color LCD 33) and the backlight of the effective rectangular key 34 and the circular key 35 (such as FIG. 2) or the background color of the effective menu item (such as FIG. 5) are selected. When the transmission format of the received broadcast is RDS, analog stereo FM broadcast, and analog mono FM broadcast, the color changes to orange, white, and pink, respectively.

  In RDS (or RBDS), it is possible to display a character string (Station Call Letter) representing a broadcasting station, the name of a song being broadcast, and the name of an artist. On HD radios compatible with RDS (or RBDS), analog and digital broadcasts are performed simultaneously. It is conceivable to receive two types of text, analog and digital, for the same content program. In addition, even when digital can be received as in Non-Delay broadcasting, the HD radio forcibly outputs analog audio, or the reception level is low when receiving IBOC broadcasting in a weak electric field environment. Even if the text is extracted from the text, there may be a situation where the text can be extracted from the digital. In such a case, when displaying the song title, it is difficult for the user to know whether the currently displayed text is analog text or digital text. It is also desired that both texts be displayed at the same time, and that the user can fix the text display to digital / analog. In response to this, in the HD radio 10, 30, 50, the text display area in the display device 17 is an analog obtained by extracting the text in the text display area separately from the color (display color) associated with each broadcast mode. Alternatively, the color is associated with digital.

  For example, when the broadcast mode of the received broadcast is IBOC broadcast, since the audio and text are both extracted from the digital broadcast portion, the color LCD 33 is displayed in blue as shown in FIG. When the broadcast mode of the received broadcast is non-delay broadcast, the display color is switched to light blue corresponding to non-delay broadcast, but the text is extracted from the digital broadcast portion, so the text display area is As shown in FIG. 4, as a color of a digital broadcast portion different from the display color, for example, blue associated with IBOC broadcast is used as a background color. When the broadcast mode of the reception broadcast is Non-Delay broadcast, when displaying text extracted from the analog broadcast portion, the text display area is orange as the color associated with RDS (or RBDS). To do. Similarly, audio cannot be extracted from the digital broadcast part due to the weak electric field environment of IBOC broadcast, but when text can be extracted, only the display color becomes white associated with the analog broadcast part, and the text display unit Is a blue background. This color-coding control is applied only on the display screen on which the color LCD 33 displays text information, and the user switches the display screen and selects not the text information but a spectrum display corresponding to time information and audio output. In this case, the color LCD 33 has only the display color.

  Further, instead of changing the background color of the text display area where text is displayed, the color of the text itself may be switched. Further, for text information, color display control relating to text may be applied by assigning colors independent of the broadcast mode, analog / digital, respectively.

  In this way, the user can recognize at a glance whether the text information such as the currently displayed song name is digitally received or received by analog FM multiplexing, etc. Even if a corresponding function exists, a desired function can be easily achieved by operating a key having the same color as the background color of the text display area or the color of the text itself (key related to user operation related to the text). Can be executed.

  FIG. 6 is a functional block diagram of the broadcast receiver 70. The broadcast receiver 70 can select one received broadcast with respect to a received broadcast that is assigned one carrier frequency and transmitted in a predetermined transmission format, and can output the broadcast content related to the received broadcast. It has become. The broadcast receiver 70 includes a broadcast mode detection unit 71, a plurality of operation units 72, an effective operation unit detection unit 73, a broadcast mode color detection unit 74, and a broadcast mode color display unit 75. Broadcast mode detecting means 71 detects the broadcast mode of the selected received broadcast. Each operation unit 72 is operated by a user. The effective operation unit detection unit 73 detects the operation unit 72 for performing an instruction to execute a function effective in the broadcast mode as an effective operation unit. Broadcast mode color detection means 74 detects the color associated with the broadcast mode as the broadcast mode color. The broadcast mode color display means 75 sets at least a portion of the background portion of the display 76 to the broadcast mode color, and displays the broadcast mode color or its related color in association with the effective operation unit.

  A specific example of the broadcast receiver 70 is the HD radio 10 and 30 described above, a specific example of the operation unit 72 is the input device 11, the rectangular key 34, and the circular key 35, and a specific example of the display 76 is the display described above. Device 17. In the broadcast receiver 70 and broadcast receivers 85 and 105 (FIGS. 7 and 8) described later, the received broadcasts that can be received and processed by the broadcast receivers are not limited to a single transmission format, It is assumed that various transmission formats may be used. For example, the broadcast receiver may receive a broadcast signal in an IBOC transmission format, an FM transmission format, an RBDS transmission format, and an AM transmission format and perform audio processing. The transmission format defining the broadcast mode is not limited to the radio broadcast transmission format, but may be a television broadcast transmission format. The broadcast mode is a broadcast mode (for example, RDS) related to an analog broadcast single transmission format. Or FM without RBDS and data broadcasting), a broadcasting mode related to a transmission format of a digital broadcasting alone, or a broadcasting mode related to a transmission format in which an analog broadcasting part and a digital broadcasting part are mixed (eg, IBOC transmission format). .

  The broadcast mode color display means 75 preferably uses the entire background portion of the display 76 as the broadcast mode color. The color of the background portion of the display 76 means the display color. By using the background portion that displays the broadcast mode color and changing the display color to the broadcast mode color, it is possible to eliminate the need to add a portion for displaying the broadcast mode color or equip an indicator.

  The operation unit 72 includes not only a physical (mechanical) operation member but also an operation unit that is drawn on a color touch panel as the display 76 and touch-operated. Hereinafter, the operation unit drawn on the color touch panel and touch-operated is appropriately referred to as “software operation unit” or “soft key”. The operation unit on the software may include menu items such as “Equalizer setting”, “Reception mode switching”, “Channel switching”, and “Seek mode switching” in FIG. All the operation units on software (for example, those having the same functions as the rectangular key 34 and the circular key 35 in FIG. 2) are included. The operation unit on the software is typically provided with explanations such as “confirm”, “up”, “down”, “left”, “right”, etc. so that the user can understand the operation contents. However, if the processing content of the touch operation of the operation unit on the software can be intuitively understood by the user according to the shape (eg, the shape is a triangle, and the vertex direction indicates up, down, left, or right as the cursor movement direction) Description can be omitted.

  Since the user can discriminate the current broadcast mode from the color of the background portion of the display 76, the user is saved the trouble of switching the screen one by one in order to know what the current broadcast mode is. For example, even if the received broadcast selected by the user is the same, the broadcast mode of the received broadcast may change over time, and the user has changed the color of the background portion of the display 76. Thus, it is possible to quickly know that the broadcast mode of the received broadcast has changed. In addition, since a sufficient area for displaying the broadcast mode color is secured, it is easy to visually recognize. In addition, the effective operation unit 72 is associated with the same color as the color of the background portion of the display 76 or a related color (eg, complementary color), and the color changes in conjunction with the broadcast mode. In addition, the user's impression is strengthened, and the user can easily remember which effective operation section is for each broadcast mode. Furthermore, even if the received broadcast selected by the user is the same, the broadcast mode of the received broadcast may change over time, and the user has changed the color of the background portion of the display 76. Thus, it is possible to quickly and accurately know that the broadcast mode and effective operation section of the received broadcast have changed.

  A specific aspect of the broadcast receiver 70 will be described.

  The broadcast mode color display means 75 changes the backlight of each effective operation unit to the broadcast mode color. There is also a method of arranging a light emitter in the vicinity of the effective operation unit for associating the broadcast mode color with the effective operation unit, but the backlight can be arranged behind the operation unit 72 and the space for arranging the operation unit 72 This is advantageous because it does not narrow. The same operation unit 72 may be assigned to a user operation for the same function execution instruction for a plurality of broadcast modes. However, if the broadcast mode is different, another function execution instruction is issued. May be assigned to a user operation. The backlight of the predetermined operation unit 72 needs to be switchable to a plurality of colors.

  The broadcast mode color display unit 75 turns off the backlight of each invalid operation unit 72. An example of the invalid operation unit 72 is the circular key 35 at the right end of FIG. An invalid color may be assigned, but if it is turned off, the color required for the backlight can be reduced.

  In the broadcast receiver 70, the broadcast mode is a broadcast mode related to a transmission format of an analog broadcast alone, a broadcast mode related to a transmission format of a digital broadcast alone, or a broadcast mode related to a broadcast in which an analog broadcast portion and a digital broadcast portion are mixed. is there.

  For example, the display 76 is a color touch panel, and the operation unit 72 is an operation unit (= operation unit on software) drawn on the color touch panel. The broadcast mode color display means 75 is used to paint the operation unit on each software to the broadcast mode color or a complementary color as its related color.

  If the color of the operation unit 72 as the operation unit on the software is set to the same broadcast mode color as the background color of the display 76, it is difficult to distinguish between the operation unit on the software and the background of the display 76. In order to deal with this, for example, the operation unit on the software has a thick black outline as a color that is clearly distinguished from the broadcast mode color, or the color of the operation unit on the software is related to the broadcast mode color. Or a complementary color.

  While the effective software controls are broadcast mode colors and complementary colors, the invalid software controls are lightened or erased from the display so that the user can understand them intuitively. It is preferable to do. It is also possible to set a default color for the operation unit on the software, leave the operation unit on the invalid software as the default color, and set the effective operation unit on the software to the broadcast mode color or complementary color. .

  FIG. 7 is a functional block diagram of the broadcast receiver 85. Similarly to the above-described broadcast receiver 70, the broadcast receiver 85 also selects one received broadcast for a received broadcast to which one carrier frequency is assigned and transmitted in a predetermined transmission format. Broadcast contents related to the received broadcast can be output. The broadcast receiver 85 includes broadcast mode detection means 86, menu item display means 87, valid menu item detection means 88, broadcast mode detection means 89, and broadcast mode color display means 90. Broadcast mode detection means 86 detects the broadcast mode of the selected received broadcast. The menu item display means 87 displays a plurality of menu items 95 to be selected by the user on the display 94. The effective menu item detecting means 88 detects a menu item 95 that is valid for user selection in the broadcast mode as an effective menu item 95. Broadcast mode detection means 89 detects the color associated with the broadcast mode as the broadcast mode color. The broadcast mode color display unit 90 sets at least a part of the background portion of the display 94 to the broadcast mode color and displays the broadcast mode color in association with the valid menu item 95.

  A specific example of the broadcast receiver 85 is the above-described HD radio 10, 50, a specific example of the display 94 is the above-described display device 17 and the color touch panel 53, and a specific example of the menu item 95 is “Equalizer setting” in FIG. , “Reception mode switching”, “Channel switching” and “Seek mode switching”. When the display 94 is a touch panel, the user selects and confirms the menu item 95 by touching the menu item 95 with a finger. If the display 94 is not a touch panel, the keys provided on the main body of the HD radio 50 are selected. It is also possible to operate the selection unit movement key and the confirmation key, and further, the selection unit movement key and the confirmation key on the remote controller.

  The display 94 preferably has the entire background portion of the display 94 as the broadcast mode color. The color of the background portion of the display 94 is the display color. By determining whether the color of the menu item 95 matches the color of the predetermined portion of the display 94, the user can efficiently confirm that the selection of the menu item 95 is valid or invalid in the currently selected received broadcast. Can know.

  A specific aspect of the broadcast receiver 85 will be described.

  The broadcast mode color display means 90 changes the background color of each menu item display area to the broadcast mode color. In the above-mentioned “channel switching” as an effective menu item of the HD radio 50, the background color of the menu item display area is set to green as the broadcast mode color. When the broadcast mode color is displayed as the background color of the menu item display area, it is possible to omit the necessity of preparing a special area for displaying the broadcast mode color.

  The display 94 is a touch panel, and the menu item displayed on the touch panel also serves as a soft key to be touched when the user confirms the selection. Since the user only needs to touch the broadcast mode color menu item 95 during user operation, the user operation can be streamlined. It is also possible to provide a key for confirming the menu item 95 that is effective for selection outside the display 94.

  The broadcast mode color display means 90 displays a broadcast mode color in association with an effective menu item 95 effective only in the current broadcast mode, and includes a plurality of broadcast modes (* the concept of a plurality of broadcast modes includes all broadcast modes). In other words, a common color associated with a plurality of broadcast modes is displayed in association with an effective menu item 95 that is effective in common. In the menu item (FIG. 5) of the HD radio 50, which is a specific example of the broadcast receiver 85, “Equalizer setting” or the like is set as an effective menu item 95 that is effective in all broadcast modes. A common color that is commonly associated with the mode (in FIG. 5, the color is represented by diagonally parallel lines with a downward slope) is assigned.

  The broadcast mode color display means 90 divides the background portion of menu items that are effective in common with a plurality of broadcast modes, and assigns each broadcast mode color associated with each of the plurality of broadcast modes to each of the background portions. Set the color of the divided part. For example, in the menu screen 61 of FIG. 5, if there is a menu item that can be selected in two broadcast modes of IBOC broadcast and TR broadcast, the display area of the menu item is divided into right and left, and left and right The divided parts are blue and green, respectively.

  In the broadcast receiver 85, the broadcast mode is a broadcast mode related to a transmission format of an analog broadcast alone, a broadcast mode related to a transmission format of a digital broadcast alone, or a broadcast mode related to a broadcast in which an analog broadcast portion and a digital broadcast portion are mixed. is there.

  In the broadcast receivers 70 and 85, the broadcast mode color is the analog broadcast portion when the broadcast mode related to the broadcast mode color is a broadcast mode of a reception broadcast in which an analog broadcast portion and a digital broadcast portion are mixed. And may be associated with the digital broadcast part separately. For example, in the above-described HD radios 30 and 50, white is assigned as the broadcast mode color to the analog broadcast portion of the IBOC broadcast and TR broadcast, and green is assigned to the digital broadcast portion of the IBOC broadcast and the digital broadcast portion of the TR broadcast. . When the audio being output is sourced from the digital broadcasting part of IBOC broadcasting, the display color, the backlight of the effective operation member, and the background color of the selectable menu item are blue. When the audio being output is sourced from the digital broadcast portion of TR broadcast, the display color, the backlight of the effective operation member, and the background color of the selectable menu item are green. If the audio being output is sourced from the analog broadcast part of IBOC broadcast or the analog broadcast part of TR broadcast, the display color and the backlight of the effective operation member and the background color of the selectable menu item are set to white. Yes.

The broadcast receiver 105 can select one received broadcast for a received broadcast that is assigned one carrier frequency and transmitted in a predetermined transmission format, and can output the broadcast content related to the received broadcast. It has become.

  The broadcast receiver 105 includes text extraction means 106, text display means 107, source determination means 108, source color detection means 109, and source color display means 110. The text extraction means 106 extracts text 115 from a received broadcast that is being selected and includes an analog broadcast portion and a digital broadcast portion. The text display means 107 displays the extracted text 115 on the display 114. The source determination means 108 determines whether the source of the text 115 is an analog broadcast part or a digital broadcast part of the received broadcast. The source color detection unit 109 detects the color associated with the source as the source color. The source color display means 110 displays the source color in association with the text 115 being displayed on the display 114.

  An example of the broadcast receiver 105 is the HD radio 10, 50 described above. An example of the display 114 is the display device 17 and the color LCD 33 described above. The text 115 displayed on the display 114 includes, for example, the title and artist name of the music currently being output as audio. The source color display means 110 preferably uses the source color as the text 115 itself or the background color in the text display area.

  For example, in FIG. 4 described above, in the period in which the broadcast mode is Non-Delay broadcast, the text “Let it be / Beats” is extracted from the digital broadcast part using the digital broadcast part as a source. The background color of the text display area to be displayed was blue with respect to the light blue color of the broadcast mode color display area. In FIGS. 2 and 3, the text “Let it be / Beats” is extracted from the digital broadcast part using the digital broadcast part of IBOC broadcast and TR broadcast as a source together with the audio, so that the text is displayed. The background colors of the text display area are blue and green, respectively, similar to the blue and green colors of the broadcast mode color display area.

  In this way, the user can grasp whether the source as the extraction source of the text displayed on the display 114 is the analog broadcast part or the digital broadcast part.

  The broadcast receiver 105 can be integrated by incorporating the broadcast receiver 105 into the broadcast receiver 70 (FIG. 6). In that case, the display 114 becomes the display 76.
