Description

  The present invention relates to a digital broadcast receiving apparatus, and more particularly to a digital broadcast receiving apparatus that outputs guide information of a digital broadcast that is scheduled to be output at a predetermined time after activation or after a reception channel is switched.

  In order to alleviate the viewer's uncomfortable feeling that the broadcast contents are not presented temporarily when the reception channel is switched for this type of device, it was acquired using audio or EPG (Electrical Program Guide) that is faster in decoding than the video signal. A digital television broadcast receiver that displays program information first is known.

However, since it takes time to decode digital audio broadcasts (digital radio broadcasts) such as acquired audio and broadcast program guides, there is a problem that it is not possible to eliminate silent sections at the time of activation or switching. In particular, this phenomenon is notable in in-vehicle audio and portable audio where high-speed decoding processing speed cannot be expected. In addition, since analog broadcasting systems are common in conventional in-vehicle audio, users who are accustomed to this do not hear sound immediately after startup (after engine startup) or after channel switching, even if it takes a short time. There was an inconvenience of having a sense of incongruity.

  According to the present invention, since the inserted information prepared in advance is output at a predetermined time after the start of the digital broadcast receiving apparatus or after the reception channel is switched, the silent state that occurs after the start of the digital broadcast receiving apparatus or after the switching of the reception channel is performed. It is possible to provide a digital broadcast receiving apparatus that can be eliminated and that does not give the user a sense of incongruity during startup.

<First Embodiment>
Hereinafter, a digital broadcast receiving apparatus 100 according to an embodiment of the present invention will be described with reference to the drawings. The digital broadcast receiving apparatus 100 of the present embodiment mainly eliminates the silent state when the audio apparatus is activated. That is, the digital broadcast receiving apparatus 100 according to the present embodiment can receive and output a digital broadcast without generating a silence state when the reception of the digital broadcast is started.

  FIG. 1 shows a block configuration of the digital broadcast receiving apparatus 100 of the present embodiment. As shown in FIG. 1, the digital broadcast receiving apparatus 100 of this embodiment has a receiving means 1, a decoding means 2, a storage means 3, a selecting means 4, and an output means 5, and specifically, In response to a start command (output start command), a ROM that stores a program that selects insertion information according to the attribute of digital broadcasting that distributes distribution information and outputs the selected insertion information before the distribution information ( (Read Only Memory) and the like, and a CPU (Central Processing Unit) functioning as the selecting means 4 and the output means 5 and the RAM functioning as the accessible storage means 3 by executing the program stored in the ROM or the like (Random Access Memory) and the like (memory 50). In addition, the digital broadcast receiving apparatus 100 receives a start command (output start command), a channel designation command, or a channel change command from the input device 200 of the audio device (not shown).

Each configuration will be described below.
“Receiving means 1” has an antenna 11 and a tuner unit 12, and receives distribution information distributed by digital broadcasting. The antenna 11 receives distribution information distributed by each digital broadcasting station. The tuner unit 12 extracts only frequency components that are predetermined reception targets from various broadcast signals that have reached the antenna 11, and outputs distribution information corresponding to the extracted frequency components to the decoding unit 2.

  The “decoding unit 2” performs predetermined digital demodulation processing on the distribution information (digital broadcast signal) extracted by the tuner unit 12. When performing this processing, the decoding unit 2 separates the audio signal (and / or video signal) and the insertion information from the distribution information extracted by the tuner unit 12, and inserts the decoded insertion information into the storage unit 3. A distribution signal such as an audio signal which has been stored in the information storage area 31 and subjected to a decoding process is output to the output means 5.

 The “storage unit 3” stores the insertion information decoded by the decoding unit 2 so that it can be read in advance. Although not particularly limited, it is preferable that the storage unit 3 is a storage medium that can be activated quickly even if it has a relatively small capacity, such as a semiconductor memory.

  The “insertion information” in the present embodiment includes digital broadcast station identification information, digital broadcast channel identification information, digital broadcast station jingle (Jingle: short commercial song), digital broadcast received by the receiving means 1. It is preferable that the program information of the content, advertisement information of the broadcasting station of digital broadcasting, or event information or other guidance information provided by the broadcasting station of digital broadcasting. In addition, the program information listed above is preferably information including information on a program title, a program performer, a song name to be broadcast, a program feature, or program topics, or other program information. . Although not particularly limited, it is preferable to include an output expiration date in the insertion information. This output expiration date is information indicating a period or an end period in which program information or the like is appropriately used. The output expiration date is referred to by the insertion information control unit 52 of the output means 5 to be described later for determining whether or not the insertion information can be output.

  Further, the insertion information of the present embodiment is stored in the storage unit 3 in association with the attribute of the digital broadcast received by the receiving unit. The “digital broadcast attribute” associated with the insertion information is not particularly limited, but is information for identifying a broadcast such as a broadcast station that distributes the digital broadcast, a channel that distributes the digital broadcast, and a provider of the digital broadcast.

  The “selecting means 4” selects insertion information previously associated with the attribute of the digital broadcast based on the attribute of the digital broadcast that distributes the distribution information. The selection unit 4 may acquire the attributes of the digital broadcast via the reception unit 1 or may be acquired via the input device 200 input by the user. For example, when a specific broadcasting station ID (attribute) and a jingle (Jingle: short commercial song: insertion information) of the broadcasting station are associated with each other, the selection unit 4 performs the broadcasting specified by the broadcasting station ID (attribute). The station jingle (insertion information) is selected, and the selected jingle is output to the output means 5.

  The “output unit 5” includes an output control unit 51 and an output unit 52, and outputs the insertion information selected by the selection unit 4 before outputting the distribution information. Although not particularly limited, when the output control unit 51 acquires the activation command of the digital broadcast receiving apparatus 100 or the digital broadcast channel change command, the output control unit 51 uses the insertion information selected by the selection unit 4 as the activation command or the digital broadcast channel. It is preferable to output immediately after acquisition of the change instruction.

  Specifically, the output control unit 51 of the present embodiment includes a distribution information output control unit 511, an insertion information output control unit 512, and a switching unit 513. The distribution information output control unit 511 outputs the distribution information decoded by the decoding unit 21 at a predetermined timing. The insertion information output control unit 512 outputs the insertion information selected by the selection unit 4 at a predetermined timing. The switching unit 53 switches between output of distribution information and output of insertion information, and controls output timing of distribution information and output timing of insertion information. Specifically, the switching unit 513 outputs insertion information before outputting the distribution information, and outputs the distribution information after outputting the insertion information. Although not particularly limited, it is preferable that the switching unit 513 (output unit 5) outputs the insertion information immediately after obtaining the activation command of the digital broadcast receiving apparatus 100 and outputs the distribution information after the insertion information is output. The switching unit 513 (output unit 5) may output the insertion information immediately after obtaining the activation command of the digital broadcast receiving apparatus 100, and output the distribution information after a predetermined time has elapsed since the insertion information output started.

 In the present embodiment, the insertion information is output before the distribution information of the digital broadcast, or the distribution information is output after the insertion information is output immediately after the activation of the digital broadcast receiving apparatus 100 (after that). Silence time at start-up caused by essential decoding processing (decoding processing) can be eliminated, and silence time unique to digital broadcasting (not occurring in analog broadcasting such as FM and AM) can be prevented from being perceived by the user. .

 Further, the insertion information output control unit 512 of the present embodiment compares the output expiration date included in the insertion information selected by the selection unit 4 with the time when the output command is acquired, and the time is within the output expiration date. If it is, the insertion information selected by the selection means 4 is output before the distribution information is output.

 The output unit 52 is a speaker and / or display compatible with digital broadcasting, and outputs information according to the control of the output control unit 51.

 Next, the control processing procedure of this embodiment is demonstrated based on FIG. FIG. 2 is a flowchart showing a control procedure when starting up the digital broadcast receiving apparatus 100 of the present embodiment.

 First, when an activation command is input and the digital broadcast receiving apparatus 100 is activated, the receiving unit 1 extracts a digital broadcast signal of a channel specified in the activation command, and starts receiving distribution information by digital broadcasting (201). . In parallel with the reception of the distribution information, the selection unit 4 acquires the attribute of the digital broadcast being received, and determines whether or not the insertion information corresponding to this attribute is stored in the storage unit 3 (S202). . When insertion information associated with the attribute of the digital broadcast being received is stored in the storage unit 3, the selection unit 4 selects the insertion information and sends it to the insertion information output control unit 512 of the output unit 5. The switching unit 53 outputs this insertion information immediately after obtaining the activation command (S203). The insertion information output here is information reminiscent of the broadcast station being received, such as a jingle (short commercial song) unique to a broadcast station of digital broadcasting, and broadcast contents. If the insertion information is not stored, decoding of the distribution information (decoding process) is started (S208).

 In parallel with the output of the insertion information, the decoding unit 2 decodes the distribution information received by the receiving unit 1, and sends the decoded distribution information to the distribution information output control unit 511 of the output unit 5 (S204). The switching unit 513 determines whether or not the output of the insertion information has been completed (S205), starts the output of the distribution information after the completion (S206), and ends the process at the start (S207).

 According to the digital broadcast receiving apparatus 100 of the present embodiment, it is possible to eliminate the silent time after activation caused by the decoding process essential for the reception of the digital broadcast, and thus it is possible to prevent the user from feeling uncomfortable. In particular, for users who are accustomed to analog broadcasting, the silent time after activation is uncomfortable with the silent time immediately after the start of digital broadcast reception. The digital broadcast receiving apparatus 100 according to the present embodiment can prevent such a silent time from being generated and prevent the user from feeling uncomfortable while receiving a digital broadcast.

 Also, according to the digital broadcast receiving apparatus 100 of the present embodiment, since the insertion information previously associated with the attribute is selected and output based on the attribute of the digital broadcast after the activation, the user can select what type ( It is possible to know from the inserted information which digital broadcasting (from which broadcasting station) is being viewed. For example, when a specific jingle of a certain broadcasting station A (attribute) is output after activation, the user can know that the broadcasting station A is selected and the broadcasting of the broadcasting station A is currently output. In other words, the user can know the broadcasting attributes of the broadcasting station from the insertion information (such as jingle), and if the insertion information is voice, look at the audio display panel, etc. or check the audio dial. There is no need to do.

Second Embodiment
The digital broadcast receiving apparatus 120 of the second embodiment is different from the first embodiment in that it includes the insertion information acquisition unit 6, but the basic configuration and operation are common. Here, overlapping explanation is avoided and different points are mainly explained.

 A block configuration of the digital broadcast receiving apparatus 120 of the present embodiment is shown in FIG. As shown in FIG. 3, the digital broadcast receiving apparatus 120 of this embodiment has an insertion information extracting unit 6. Other configurations are the same as those of the first embodiment shown in FIG.

 The insertion information acquisition means 6 of the present embodiment extracts the insertion information associated with the attribute of the digital broadcast that distributes the distribution information from the distribution information received by the reception means 1, and stores the extracted insertion information. 3 is stored. An identifier is attached to the insertion information so that it can be identified as the insertion information, and the insertion information acquisition unit 6 can extract the insertion information from the distribution information. That is, the digital broadcast receiving apparatus 120 of this embodiment does not store the insertion information in the storage unit 3 in advance, but acquires it from the distribution information of the received digital broadcast and stores it in the storage unit 3.

Insertion information and distribution information output processing of the digital broadcast receiving apparatus according to the present embodiment follows the control procedure shown in FIG. Here, processing related to information acquisition different from that of the first embodiment until the insertion information is acquired and stored in the storage unit 3 will be described based on the flowchart of FIG.
The flow shown in FIG. 4 is started every time the reception channel of the digital broadcast receiving apparatus 120 changes, that is, every time the frequency signal to be received extracted by the tuner unit 12 is changed.

 In this example, this is processing when the user inputs a channel change command and the received channel is changed. The tuner unit 12 changes the channel of the digital broadcasting being received to the designated channel, and outputs the distribution information received on the channel after the change to the decoding unit 21. The decoding unit 21 performs a predetermined decoding process (MPEG-2 Audio AAC) on the acquired distribution information of the specific frequency. When this process is performed, the decoding unit 21 of the decoding unit 2 also performs a decoding process on the insertion information included in the distribution information.

 The insertion information extraction means 6 extracts the insertion information from the distribution information and starts acquiring it (S301). The insertion information in this example is common to the insertion information in the first embodiment. When the acquisition of the insertion information is completed (S302), the acquired insertion information is stored in the insertion information storage area 31 of the storage means 3. If the power of the audio apparatus including the digital broadcast receiving apparatus 110 is turned off before and after the acquisition is completed, the processing is terminated (S304, S306). When the audio device (ACC) is not turned off and a predetermined time has elapsed (S305), the insertion information acquisition process is started again (from S305 to S301).

 According to the digital broadcast receiving apparatus 110 of the present embodiment, it is possible to eliminate the silent time after activation caused by the decoding process essential for receiving the digital broadcast, and thus it is possible to prevent the user from feeling uncomfortable. In particular, for users who are accustomed to analog broadcasting, the silent time after activation is uncomfortable with the silent time immediately after the start of digital broadcast reception. The digital broadcast receiving apparatus 100 according to the present embodiment can prevent such a silent time from being generated and prevent the user from feeling uncomfortable while receiving a digital broadcast.

 Also, according to the digital broadcast receiving apparatus 110 of the present embodiment, since the insertion information previously associated with the attribute is selected and output based on the attribute of the digital broadcast after activation, the user can select what kind of digital Whether the broadcast is being watched can be known from the inserted information. For example, when a specific jingle of a certain broadcasting station A (attribute) is output after activation, the user can know that the broadcasting station A is selected and the broadcasting of the broadcasting station A is currently output. That is, the user can know the broadcasting attributes of the broadcasting station or the like from the insertion information (such as jingle), and when the insertion information is voice information, the user can look at the audio display panel or the audio dial. There is no need to check.

<Third Embodiment>
The digital broadcast receiving apparatus 120 of the third embodiment has a function (first receiving means) for receiving distribution information and insertion information, particularly for the purpose of eliminating the silent time that occurs when a channel is changed. It differs from the first embodiment in that it has a function for receiving (second receiving means) and an insertion information acquiring means 7 for acquiring insertion information from distribution information received by the second receiving means. The configuration and operation are the same as those in the first embodiment. Here, overlapping explanation is avoided and different points are mainly explained.

 A block configuration of the digital broadcast receiving apparatus 120 of the present embodiment is shown in FIG. As shown in FIG. 5, the digital broadcast receiving apparatus 120 according to the present embodiment includes a first antenna 11, a first tuner unit 12, a second antenna 13, a second tuner unit 14, and a first decoding unit 21. The second decoding unit 22 and the insertion information acquisition means 7 are included.

 The first antenna and the first tuner unit 12 (first receiving means) receive distribution information distributed by digital broadcasting of the channel specified in the output command input by the user. The first tuner unit 12 extracts only frequency signals to be received by extracting only predetermined frequency components designated by the user from various broadcast signals that have reached the first antenna 11, and extracts the extracted digital signals. Broadcast (for example, digital radio broadcast) signals are output.

  The second antenna 13 and the second tuner unit 14 (second receiving means) receive distribution information distributed by receivable digital broadcasting. The second tuner unit 14 is a tuner that is used to obtain program information to be output at the time of channel change regardless of the user's intention. After startup, the second tuner unit 14 automatically searches for a receivable channel and acquires the channel. Are output to the second decoding unit 22.

 The first decoding unit 21 (first decoding unit) decodes the distribution information received by the first tuner unit 12. The first decoding unit 21 performs predetermined digital demodulation processing (MPEG-2 Audio AAC demodulation) on the digital broadcast signal extracted by the first tuner unit 12, and outputs distribution information to the output unit 5.

 The second decoding unit 22 (second decoding unit) decodes the insertion information received by the second tuner unit 14. The second decoding unit 22 performs predetermined decoding processing on the broadcast signal extracted by the second tuner unit 14 to acquire insertion information such as program information output at the time of channel change, and acquires the acquired channel number and The data are stored in the storage unit 3 in association with each other. The second decoding unit 22 also sends the channel number from which the program information and the like have been acquired to the selection unit 4. The selection means 4 stores this channel number. As with the insertion information of the first embodiment, the insertion information that is output when the channel is changed includes the digital broadcast broadcasting station identification information, the digital broadcasting channel identification information, and the digital broadcasting broadcasting station jingle received by the receiving means. , Digital broadcast content program information, digital broadcast broadcast station advertisement information, or digital broadcast broadcast station event information and other guidance information, preferably program title, program performer, broadcast It is preferable that the program information including information on the name of the music to be played, the special feature of the program, or the topics of the program or other programs is used as the insertion information. Further, as in the first embodiment, the insertion information may include an output expiration date.

 The insertion information acquisition unit 7 acquires insertion information from the distribution information received by the second tuner unit 14 (second reception unit) and decoded by the second decoding unit 22. An identifier is attached to the insertion information so that the insertion information can be identified, and the insertion information can be acquired from the distribution information. The insertion information acquisition unit 7 stores the acquired insertion information in the storage unit 3.

 When the channel designated in the output command is changed, the selection unit 4 selects insertion information associated with the attribute based on the digital broadcast attribute of the channel after the change. When the selection unit 4 detects a channel change in the distribution information extracted by the first tuner unit 12, the selection unit 4 performs processing for selecting insertion information. When the user changes the reception channel using a preset button for selecting a reception broadcast station registered in advance, the selection unit 4 selects insertion information relating to the channel of the preset button pressed by the user. In addition, when the user changes the reception channel by channel search (seek), the selection unit 4 selects insertion information regarding the next receivable channel at the start of seek.

 Using the channel change as a trigger, the switching unit 513 of the output unit 5 outputs the insertion information selected by the selection unit 4 immediately after the channel change, and then outputs the demodulated distribution information.

 Under the control of the switching unit 513, the insertion information output control unit 512 outputs the insertion information acquired by the insertion information acquisition unit 7 immediately after the channel change. Furthermore, the distribution information output control unit 511 outputs the distribution information demodulated by the first decoding unit 21 according to the control of the switching unit 513. The distribution information output control unit 511 instructs the output of distribution information related to the channel of the preset button pressed by the user when the reception channel is changed by a preset button for selecting a reception broadcast station registered in advance by the user. In addition, when the user changes the reception channel by channel search (seek), the distribution information output control unit 511 instructs the output of distribution information regarding the next receivable channel at the start of seek.

 Next, based on FIG.6 and FIG.7, the control procedure of the digital broadcast receiver 120 of 3rd Embodiment is demonstrated.

 The flow shown in FIG. 6 is started when the channel number received by the first tuner unit 12 is changed by the user (S800). When the distribution information of the specific frequency extracted by the first tuner unit 12 is changed by the user, the selection unit 4 has already acquired the insertion information corresponding to the changed broadcast channel, and the storage unit 3 (insertion information storage) It is searched whether it is registered in the area 31) (S801). For example, when the user changes the reception channel using the preset button, the insertion information corresponding to the channel registered in the pressed preset button is searched to determine whether or not it is registered as the insertion information. . When the user changes the channel by channel search (seek), the insertion information corresponding to the channel that can be received next is searched to determine whether or not it is registered as insertion information. If the insertion information corresponding to the changed broadcast channel is registered, the process proceeds to S802. If the insertion information is not registered, the first decoding unit 21 distributes the distribution information distributed through the changed channel. (S808).

 If the insertion information associated with the changed channel is registered in the storage unit 3, the selection unit 4 selects the insertion information and outputs it to the output unit 5. The insertion information output control unit 512 Then, an output command for the selected insertion information is prepared (S802). The switching unit 513 controls the output timing so that the selected insertion information is output immediately after the channel change (S803).

 The first decoding unit 21 starts the distribution information decoding process (MPEG-2 Audio AAC demodulation process) after the process of S803 or in parallel with the processes of S801 to S803 (S804).

 The switching unit 513 determines whether or not the output of the previously inserted insertion information has been completed (S805). When the output of the insertion information is completed, the switching unit 513 starts outputting the distribution information and switches the information to be output. Although not particularly limited, audio information having a short time required for demodulation processing among the distribution information may be output first. At the time when the output of the insertion information is completed, the distribution information decoding process by the first decoding unit 21 is also in progress, so that the distribution information is output next to the insertion information so that no silence time occurs after the channel change. can do.

  FIG. 7 is a flowchart showing insertion information acquisition processing. The process of FIG. 7 is continued after the digital broadcast receiving apparatus 120 is activated until the power is turned off.

  First, when the radio receiver is activated (S900), the second tuner unit 14 starts searching for a receivable channel and, upon detecting a receivable channel, receives distribution information from the obtainable channel, Output to the second decoding unit 22. The second decoding unit 22 performs predetermined composite processing on the distribution broadcast received by the second tuner 14. The insertion information acquisition unit 7 acquires insertion information such as program information from the decrypted distribution information based on the identifier of the insertion information attached to the insertion information (S901). When the acquisition of the insertion information is completed (S902), the insertion information acquisition unit 7 stores the insertion information acquired by the second decoding unit 22 and the channel number (digital broadcast attribute) from which the insertion information is acquired in association with each other. Store in the means 3 (S903, 904). The channel number is also sent to the output means 5.

  The processing of S901 to 904 is performed until the insertion information (including program information) of all receivable channels is acquired (S905, S906). The order of obtaining the insertion information may be searched in the order of the channel numbers, or the preset channels may be preferentially processed. By preferentially processing preset channels, it is possible to prepare insertion information for channels (digital broadcasting) that are frequently used and changed frequently by users at an early stage.

  Thereafter, when a predetermined time has elapsed, search for receivable channels and acquisition of insertion information are started again (S907). Here, the re-search is started considering only the time. However, since the radio program is determined by the time, the re-search may be started at a predetermined time. In addition, when the digital broadcast receiving apparatus is mounted on a vehicle, the channel that can be acquired may vary depending on the position of the vehicle, so the timing for starting the re-search depends on the position information, travel time, and / or travel distance. It may be defined.

  6 and 7 are combined to output insertion information such as program information corresponding to the attributes of the received broadcast during the silence period generated by the decoding process performed when the reception channel is changed, which is unique to digital broadcasting. be able to.

 According to the digital broadcast receiving apparatus 100 of the present embodiment, it is possible to eliminate the silent time at the time of channel change caused by the decoding process essential for the reception of the digital broadcast, and thus it is possible to prevent the user from feeling uncomfortable. . In particular, for users who are accustomed to analog broadcasting, the silent time at the time of changing the channel feels uncomfortable with the silent time at the time of changing the channel of digital broadcasting. The digital broadcast receiving apparatus 100 according to the present embodiment can avoid such a silent time when changing a channel while receiving a digital broadcast, and can prevent the user from feeling uncomfortable.

 In addition, according to the digital broadcast receiving apparatus 120 of the present embodiment, since the insertion information previously associated with the attribute is selected and output based on the attribute of the digital broadcast when the channel is changed, It is possible to know from the insertion information whether the digital broadcast of the channel is to be selected. For example, when distribution information of a program selected by a certain broadcast station A is received, the program information of the program ID (attribute), the name of a performer such as personality, the name of a song, and the contents of a special feature are output. By doing so, the user can know the selected packaging program. That is, the user can know the attribute of the broadcast station or broadcast program selected by changing the channel from the insertion information (program information). If the insertion information is audio information, the user can look at the audio display panel or the like. There is no need to check the dial or watch.
