When the process is started, the main controller 12 first obtains the character information and information on the reception state included in the signal from the demodulator 14 based on the signal currently being received in step 21. As this character information, for example, the name of the broadcasting station being received, the name of the song being received (listened), the artist or genre, or information relating to the genre of the broadcast program is applicable. The information regarding the reception state corresponds to, for example, information regarding the channel being received and the broadcast mode of the broadcast being received.

  Broadcast modes include analog broadcast, digital broadcast, monaural broadcast, stereo broadcast, IBOC hybrid broadcast, IBOC simultaneous broadcast, IBOC full digital broadcast, Tomorrow Radio broadcast, non-delay broadcast (non-delay broadcast) RDS / RBDS broadcasting, etc. Non-delayed broadcast is a type of service in IBOC broadcast, and is a broadcast mode in which analog audio is preferentially output in the case of broadcast content where real-time characteristics are important, such as baseball broadcasts.

  Next, in step 22, the main controller 12 generates text used to display a single line of character string on the display device 16 based on the plurality of information acquired in step 21. At that time, the text includes text representing two or more pieces of information. That is, the character string based on the character information acquired in step 21 is added with a character string representing information on the reception state acquired in step 21 as additional related information different from the information based on the character information. Generate text to display columns.

  Next, in step 23, the main controller 12 outputs the generated text to the display device 16, and ends the processing of FIG. The output text is provided for display by the display device 16, and the content is displayed as a one-line character string and presented to the user.

  FIG. 3 shows a display example on the display device 16 (FIGS. (B) to (h)) in comparison with a conventional example (FIG. (A)). In this example, TOMOC radio broadcast (hereinafter referred to as “IBOC-TR broadcast”) based on the IBOC method including analog and digital simulcast and two sub-channels with a broadcast frequency of 100.1 [MHz]. The case of receiving is shown.

  In the conventional example, “WXYZ-FM” indicating the name of the broadcasting station as shown in FIG. 5A is always displayed on the display screen of the display device regardless of the received contents. . This display format is defined as a station call letter specification in IBOC broadcasting. The first four characters “WXYZ” are primary information, and the last three characters “−FM”. Is optional information. On the other hand, in this embodiment, characters representing a broadcast mode and a reception channel obtained based on the received signal are added as additional information to “WXYZ” as the primary information, and FIG. The display as shown in (h) is performed.

  That is, FIG. 5B shows a display example when analog monaural broadcasting is received. In this example, as shown in the figure, for the primary information “WXYZ” of the broadcast station name, “FM” indicating that an analog FM broadcast is received, and “” indicating that the broadcast is monaural.

In this example, as shown in the figure, for the primary information “WXYZ” of the broadcast station name, “HD” indicating that an HD radio broadcast as a digital broadcast is received, and the broadcast is monaural. A character string “WXYZ HD M” combined with “M” indicating “” is displayed.

  FIG. 5E shows a display example when digital stereo broadcast is received. In this example, as shown in the figure, for the primary information “WXYZ” of the broadcast station name, “HD” indicating that an HD radio broadcast that is a digital broadcast is received, and the broadcast is stereo. A character string “WXYZ HD S” combined with “S” indicating “” is displayed.

  As described above, in the examples of FIGS. 7B to 7E, with respect to the primary information “WXYZ” of the broadcast station name, whether the broadcast being received is analog or digital, and whether it is monaural or stereo Characters indicating the broadcast mode are added and displayed. In the examples of FIGS. 5F to 5H, characters indicating information about the channel being received are further added and displayed.

  That is, FIGS. 5F to 5H show display examples when the main channel, the sub channel 1 and the sub channel 2 are received as digital stereo broadcasts, respectively. In these examples, as shown in (f) to (h) in the figure, for the primary information “WXYZ” of the broadcast station name, “HD”, which indicates that an HD radio broadcast that is a digital broadcast is received, In addition to “S” indicating that the broadcast is stereo, the character strings “WXYZ HD1S”, “WXYZ HD2S” obtained by combining “1”, “2”, and “3” indicating the reception channel, And “WXYZ HD3S” are displayed. “1”, “2”, and “3” indicate that the reception channels are the main channel, the sub channel 1, and the sub channel 2, respectively.

  FIG. 4 shows another display example on the display device 16 in comparison with the conventional example. This figure shows a case where an IBOC broadcast in which analog and digital simultaneous broadcasts are received at 1000 [kHz]. In the conventional example, the primary information “WXYZ” of the broadcast station name is always displayed as shown in FIG. On the other hand, in the present embodiment, text representing the broadcast mode of the received broadcast is added to display as shown in FIGS.

  That is, FIG. 4B shows a display example when analog broadcasting is received. In this example, a character string “WXYZ AM” in which “AM” indicating that an analog AM broadcast is received is displayed with respect to the primary information “WXYZ” of the broadcast station name. FIG. 5C shows a display example when digital broadcasting is received.

  FIG. 5 shows the front panel portion of the receiver. Reference numeral 51 in the figure denotes a display unit in the display device 16 in FIG. In the same figure, another display example is shown. That is, in the display unit 51, “FM1” indicating the selected band, primary information “WXXX” of the broadcast station name of the received broadcast, “HD” indicating that the broadcast is an HD radio broadcast, “2” indicating that the channel being received is sub-channel 1 and “S” indicating that the broadcast of the channel is a stereo broadcast are combined and displayed in one line.

  FIG. 6 shows an example in which the same display content as the display content in the display unit 51 of FIG. In this example, instead of “HD” in the display unit 51 of FIG. 5, a symbol designating “HD” is displayed at the same position. Also, bold “ST” is displayed in place of “S” in FIG.

  FIG. 7 shows still another display example (FIGS. (B) to (d)) on the display device 16 in comparison with a conventional display example (FIG. (A)). In this example, FM multiplex broadcasting or digital broadcasting is received at a certain frequency or channel, and “Beatles” is received as song artist information of the music broadcast by the broadcasting.

  Conventionally, when receiving an RDS / RBDS broadcast or a digital broadcast, based on the song title information and song artist information included as digital information in the received signal, the song being broadcast as shown in FIG. There is known a receiving apparatus having a function of displaying a title and an artist name. On the other hand, in the present embodiment, not only the case where the broadcast station name (station call letter) as shown in FIG. 3 is displayed, but also the song title information, song artist information, etc. about the music being received. In the case of displaying, various information is added and displayed as shown in (b) to (d) of FIG.

  That is, FIG. 5B shows a display example when the main channel in Tomorrow radio broadcasting is received. In this example, the character string “M: Beatles” in which “M” indicating that the main channel in Tomorrow Radio Broadcasting is received is combined with the artist name “Beatles” of the music being received. Is displayed.

  FIG. 6C shows a display example when a sub-channel in Tomorrow radio broadcasting is received. In this example, the character string “S: Beats” in which “S” representing that a sub-channel in Tomorrow Radio Broadcasting is received is combined with the artist name “Beatles” of the music being received. Is displayed.

  FIG. 4D shows a display example when an RBDS broadcast is received. In this example, a character string “R: Beatles” in which “R” indicating that the RBDS broadcast is received is displayed before the artist name “Beatles” of the music being received.

  In addition, you may make it display the character string regarding these music in the 2nd line of a display part similarly to the case of the prior art example of FIG. That is, the character string related to the broadcasting station as shown in FIGS. 3B to 3H is displayed on the first line, and the character string related to the music as shown in FIGS. 7B to 7D is displayed on the second line. You may do it.

  According to the above-described embodiments of FIGS. 1 to 7, a conventional indicator such as a broadcast mode (broadcast content) is further added to the minimum necessary character string conventionally displayed according to the specification of the text received by the receiving device. Since character strings and symbols representing other information that were displayed in the display are added and displayed, more information can be presented in a limited display area without switching the display mode. it can. At that time, it is possible to present more information in a form that is easy for the user to recognize by changing or omitting part of the characters representing the station call letter or the artist name of the song. . In particular, in an in-vehicle receiving apparatus in which the display area of the display unit exists only for the number of lines of about one or two lines, these advantages are great.

  Moreover, since the display position is not fixed about the character and symbol showing the information added, it is not necessary to ensure the fixed display position like the case of an indicator. Therefore, more information can be presented, for example, by scrolling the combination of displayed character strings and symbols. Conventionally, each information that has been displayed separately as information displayed as a character string based on character data included in the received signal and information displayed by an indicator such as a broadcast mode or a reception channel, Since the symbols are integrated as a combination of symbols and displayed at the same time, more information can be displayed in a sufficiently large size that can be easily recognized by the user in a limited display area. Therefore, the display by the indicator can be made unnecessary. Regardless of the display mode selected by the user, information regarding the broadcast mode and the reception channel of the broadcast being received can always be displayed with an additional character string or symbol representing the information.

  By the way, there is also known a receiving apparatus having a display mode that displays various graphics depending on the display mode and does not display even information such as frequency and broadcast station name. In addition, in the case of a receiving apparatus in which the display unit has a display area having a size of about one or two lines, it may not be possible to display all information simultaneously.

  Therefore, in the receiving apparatus according to another embodiment of the present invention, the reception state is constantly monitored, and when there is a predetermined transition in the reception state, the state transition is performed in order to notify the user to that effect. Characters or symbols to be represented are preferentially displayed in a predetermined display area of the display device regardless of the display mode set by the user for a certain period of time. The configuration of the receiving apparatus is the same as in FIG.

  As the transition of the reception state, for example, the transition of the broadcast mode performed by the broadcast station of the receiving broadcast or the transition performed by the receiving apparatus corresponds. Examples of transitions between broadcast modes include transitions between broadcasts including digital broadcasts and analog-only broadcasts, transitions between stereo broadcasts and monaural broadcasts, transitions between states including and not including sub-channels in digital broadcasts, and IBOC broadcasts Transition between hybrid broadcasting and full digital broadcasting in IBOC, or transition between hybrid broadcasting and non-delayed (non-delayed) broadcasting in IBOC broadcasting.

  As the transition of the reception state performed by the receiving device, for example, the transition between the state of receiving the main channel and the state of receiving the sub channel, analog audio in the case of receiving the IBOC broadcast, This corresponds to the transition between the receiving state and the state of receiving digital audio. The transition between the former main channel and sub-channel is performed based on the user's instruction operation, but the latter transition between analog and digital depends on the electric field strength of the received signal, etc., regardless of the user's instruction operation. Based on this, the main controller 12 performs this.

  FIG. 8 is a flowchart showing a part of processing by the main controller 12 in the present embodiment. This process is performed at predetermined intervals. When the process is started, first, at step 71, the main controller 12 determines whether or not there is a transition between predetermined reception states, for example, a transition of a broadcast mode from an analog-only broadcast to a broadcast including a digital broadcast. If it is determined that there is a transition, the process proceeds to step 72. If it is determined that there is no transition, the process proceeds to step 74.

  In step 72, the main controller 12 starts a timer. Next, in step 73, display of characters or symbols indicating that there has been a transition between the predetermined reception states is started. For example, when the broadcast mode transitions to a broadcast including the above-described digital broadcast, the display of a symbol that symbolizes the digital broadcast is started. Instead of this display, lighting of a predetermined indicator may be started. Thereafter, the process of FIG. 7 is terminated.

  In step 74, it is determined whether or not the timer has counted a predetermined period. If it is determined that the predetermined period has not been counted, the processing in FIG. 7 is terminated. If it is determined that the count has been made, the process proceeds to step 75. In step 75, the display state on the display device 16 is returned to the display state in the original display mode before the display in step 73 is started. However, the display content when returning to the original display mode may change from that before the transition due to the relationship between the display mode and the reception state after the transition.

  According to the present embodiment, when there is a transition between predetermined reception states, a display indicating that is performed for a predetermined period, and after the period has elapsed, the display state is restored to the original display mode. A lot of information can be presented to the user regardless of the display mode. For example, when there is a transition of the broadcast mode to the broadcast including the above-described digital broadcast, the user sees the display indicating the state transition, knows that the digital broadcast is included in the broadcast wave, and receives the digital broadcast. Thus, the receiving apparatus can be set.

  In addition, this invention is not limited to the above-mentioned embodiment, It can deform | transform and implement suitably. For example, in the above description, a receiving device having a function of receiving IBOC broadcasting and RDS / RBDS broadcasting has been described. However, the present invention is not limited to this, and the receiving device receives a broadcast based on a broadcasting method capable of receiving text. If so, the present invention can also be applied to a receiving apparatus that receives broadcasts by other broadcast methods.
