Description

この発明は、デジタルラジオ放送、デジタルテレビ放送等のデジタル放送の受信信号を録音する放送内容録音装置に関するものである。   The present invention relates to a broadcast content recording apparatus for recording a received signal of a digital broadcast such as a digital radio broadcast or a digital television broadcast.

この種の放送内容録音装置は、受信信号を録音中に電源をオフした場合、当然、受信信号は途中までしか録音されない。そこで、希望する受信信号を全て録音するためには、その受信信号の録音終了まで電源のオンを継続することが必要であり、ユーザは自由に電源をオフすることができない。特に、車に搭載された放送内容録音装置の場合は、目的地についても録音終了までは、エンジンを切りＡＣＣ（アクセサリ）をオフ状態にして車を降りることができず不便である。   In this type of broadcast content recording apparatus, when the power is turned off during recording of the received signal, the received signal is naturally recorded only halfway. Therefore, in order to record all desired received signals, it is necessary to continue to turn on the power until recording of the received signal is completed, and the user cannot freely turn off the power. In particular, in the case of a broadcast content recording device mounted on a car, it is inconvenient that the engine cannot be turned off and the ACC (accessory) can be turned off until the end of recording even at the destination.

そこで、従来は、例えば、特許文献１に記載されているように、受信信号が音楽放送の場合、音楽放送の付加情報に含まれる演奏期間制御データに基づき、自動録音を指示した曲を演奏開始時点から演奏終了まで録音させるものがあるが、録音中にユーザの本意ではない電源オフ状態が生じた場合の対処については何等考慮されていない。このため、例えば車に搭載された放送内容録音装置では、エンジンを切りＡＣＣ（アクセサリ）オフ状態になった場合は、放送内容録音装置の主電源が切れて、希望する受信信号の録音中であっても該録音が中断されてしまうという不都合があった。   Therefore, conventionally, as described in Patent Document 1, for example, when the received signal is a music broadcast, the performance of the music instructed to be automatically recorded is started based on the performance period control data included in the additional information of the music broadcast. Some recordings are made from the time until the end of the performance, but no consideration is given to what to do when a power-off state that is not the user's intention occurs during recording. For this reason, for example, in a broadcast content recording device installed in a car, when the engine is turned off and the ACC (accessory) is turned off, the main power of the broadcast content recording device is turned off and the desired received signal is being recorded. However, there is a disadvantage that the recording is interrupted.

特開平９−７４３６５号公報（［００２１］〜［００２３］、図４）JP-A-9-74365 ([0021] to [0023], FIG. 4)

従来の放送内容録音装置は以上のように構成されているので、受信信号を録音中に電源のオフ操作をした場合、その電源オフ時点で録音が中断し、希望する受信信号を最後まで録音することができないという課題があった。   Since the conventional broadcast content recording device is configured as described above, if the power is turned off while recording the received signal, the recording is interrupted when the power is turned off and the desired received signal is recorded to the end. There was a problem that it was not possible.

この発明は上記のような課題を解消するためになされたもので、受信信号を録音中に電源のオフ操作を行っても、その受信信号を最後まで録音できるようにした放送内容録音装置を得ることを目的とする。   The present invention has been made to solve the above-described problems, and provides a broadcast content recording apparatus that can record a received signal to the end even if the power is turned off during recording of the received signal. For the purpose.

この発明に係る放送内容録音装置は、デジタル放送の受信信号を処理する信号処理部と、この信号処理部で処理された受信信号を記憶する記憶媒体と、前記信号処理部および前記記憶媒体に対し電力を供給する電源部と、前記電源部と電源との接続路に設けたスイッチと、前記スイッチをオフする指示を受けると録音中であるか否かを判断し、録音中でなければ直ちに前記スイッチをオフし、録音中のときは前記受信信号の途切れを検出して該スイッチをオフする制御部とを備えたものである。   The broadcast content recording apparatus according to the present invention includes a signal processing unit that processes a received signal of a digital broadcast, a storage medium that stores the reception signal processed by the signal processing unit, and the signal processing unit and the storage medium. When a power supply unit for supplying power, a switch provided in a connection path between the power supply unit and the power supply, and receiving an instruction to turn off the switch, it is determined whether recording is in progress. A controller that turns off the switch by turning off the switch and detecting the interruption of the received signal during recording.

この発明によれば、受信信号を録音中に電源オフを指示しても、その録音中の受信信号が終了したことを検出して、受信機器への電源供給をオフするように構成したので、その受信信号を最後まで確実に録音できるという効果がある。   According to the present invention, even if it is instructed to turn off the power during recording of the received signal, it is detected that the received signal being recorded has ended, and the power supply to the receiving device is turned off. There is an effect that the received signal can be reliably recorded to the end.

以下、この発明の実施の一形態を図面について詳細に説明する。
実施の形態１．
以下、図面について、車に搭載した放送内容録音装置で受信した受信信号を録音する場合を例に実施の形態を説明する。
図１は実施の形態１である放送内容録音装置の構成を示すブロック図、図２はその動作を説明するフローチャートである。図１において、アンテナ１を備えたチューナ２の出力側には、ＨＤＤ（Ｈａｒｄ Ｄｉｓｋ Ｄｒｉｖｅ）４とＤ／Ａ（デジタル／アナログ）コンバータ５とが接続され、Ｄ／Ａコンバータ５の出力側には増幅部６とスピーカ７が順次直列に設けられている。図示しないバッテリから電源部１０に至る接続路に設けられたスイッチ８は制御部としてのマイクロコンピュータ９によってオン／オフ制御される。電源部１０は図に省略した電源供給路によって、チューナ２、信号処理部３、ＨＤＤ４、Ｄ／Ａコンバータ５、アンプ６のそれぞれに電力を供給する。マイクロコンピュータ９はこれらとは別電源が供給される。マイクロコンピュータ９は信号処理部３との間で互いに通信を行うとともに、図示しない操作部から操作信号、図示しないキースイッチからＡＣＣ信号を受け、ＨＤＤ４に録音の開始／終了、再生の開始を指示し、スイッチ８をオン／オフ制御する。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
Embodiment 1 FIG.
In the following, an embodiment will be described with reference to an example of recording a received signal received by a broadcast content recording device mounted on a car.
FIG. 1 is a block diagram showing the configuration of the broadcast content recording apparatus according to the first embodiment, and FIG. 2 is a flowchart for explaining the operation thereof. In FIG. 1, an HDD (Hard Disk Drive) 4 and a D / A (digital / analog) converter 5 are connected to an output side of a tuner 2 having an antenna 1, and an output side of the D / A converter 5 is connected to an output side. The amplifying unit 6 and the speaker 7 are sequentially provided in series. A switch 8 provided on a connection path from a battery (not shown) to the power supply unit 10 is on / off controlled by a microcomputer 9 as a control unit. The power supply unit 10 supplies power to each of the tuner 2, the signal processing unit 3, the HDD 4, the D / A converter 5, and the amplifier 6 through a power supply path (not shown). The microcomputer 9 is supplied with a power supply different from these. The microcomputer 9 communicates with the signal processing unit 3 and receives an operation signal from an operation unit (not shown) and an ACC signal from a key switch (not shown), and instructs the HDD 4 to start / end recording and start reproduction. The switch 8 is turned on / off.

次に動作を説明する。アンテナ１より入力されたデジタル放送波はチューナ２で周波数変換された後、信号処理部３に供給される。信号処理部３で処理されたデジタル受信信号はＤ／Ａコンバータ５でアナログ受信信号に変換される。このアナログ受信信号はアンプ６で増幅された後、スピーカ７に供給されて音声出力される。この受信状態において、デジタル受信信号を録音するために、ユーザが図示しない操作部を操作してマイクロコンピュータ９に録音を指示すると、マイクロコンピュータ９はＨＤＤ４に録音開始を通知し録音状態となる。   Next, the operation will be described. The digital broadcast wave input from the antenna 1 is frequency-converted by the tuner 2 and then supplied to the signal processing unit 3. The digital reception signal processed by the signal processing unit 3 is converted into an analog reception signal by the D / A converter 5. The analog reception signal is amplified by the amplifier 6 and then supplied to the speaker 7 for sound output. In this reception state, in order to record the digital reception signal, when the user operates the operation unit (not shown) to instruct the microcomputer 9 to record, the microcomputer 9 notifies the HDD 4 of the start of recording and enters the recording state.

この録音状態において、車のエンジンを切り、ＡＣＣをオフ状態にした場合の動作を図２のフローチャートについて説明する。マイクロコンピュータ９はＡＣＣのオフ指示を受けると（ステップＳＴ１１）、録音中か否かを判断する（ステップＳＴ１２）。そして、録音中でなければ直ちにスイッチ８をオフするが。録音中のときは、信号処理部３との間で通信を行い、受信信号とともに放送されてくる情報、例えばデジタル受信信号が楽曲の場合、その楽曲の長さ時間−該楽曲の受信開始から受信停止指示までの経過時間＝残り時間が「０」であるかを判断し（ステップＳＴ１３）、その楽曲の残り時間が「０」であればスイッチ８をオフする（ステップＳＴ１４）。なお、ステップＳＴ１３の判断で楽曲の残り時間が「０」でなければ、「０」になるまでステップＳＴ１３の判断を繰り返す。   The operation when the vehicle engine is turned off and the ACC is turned off in this recording state will be described with reference to the flowchart of FIG. When the microcomputer 9 receives the ACC off instruction (step ST11), it determines whether or not recording is in progress (step ST12). If the recording is not in progress, the switch 8 is turned off immediately. When recording is in progress, communication is performed with the signal processing unit 3, and when the information broadcast together with the received signal, for example, a digital reception signal is a music, the length of the music-received from the start of reception of the music It is determined whether the elapsed time until the stop instruction = remaining time is “0” (step ST13). If the remaining time of the music is “0”, the switch 8 is turned off (step ST14). If it is determined in step ST13 that the remaining time of the music is not “0”, the determination in step ST13 is repeated until “0”.

以上のように、実施の形態１によれば、ユーザが受信信号の録音中に任意にＡＣＣ信号をオフする指示を行っても、バッテリから電源部１０に至る経路のスイッチ８を直ちにオフすることなく、例えばデジタル受信信号が楽曲の場合、その楽曲の残り時間が「０」となったことから、その受信信号が終了したことを検出して、電源部１０に対する電源供給をオフする。この結果、ユーザは録音状態か否かに気を使うことなく、いつスイッチオフの指示を行っても、その受信信号を最後まで確実に録音することができる。   As described above, according to the first embodiment, even if the user gives an instruction to arbitrarily turn off the ACC signal during recording of the received signal, the switch 8 on the path from the battery to the power supply unit 10 is immediately turned off. For example, when the digital reception signal is a music piece, the remaining time of the music piece is “0”. Therefore, the end of the reception signal is detected and the power supply to the power supply unit 10 is turned off. As a result, the user can reliably record the received signal to the end regardless of whether the user is in a recording state or not, regardless of whether or not the switch is turned off.

実施の形態２．
図３は実施の形態２である放送内容録音装置の構成を示すブロック図であり、受信信号がニュース等のように長さが不明で、楽曲のように楽曲の長さ時間や該楽曲の受信開始から受信停止指示までの経過時間が得られない場合にも対応できるように構成したもので、Ｄ／Ａコンバータ５から出力されたアナログ信号の音声レベルを検出するアナログ音声レベル検出器１１を備え、予め設定したアナログ音声レベル値以下であれば無音と判断、つまり、受信信号の終了と判断して、その判断結果をマイクロコンピュータ９に通知する構成である。なお、他の構成は図１と同一であるから、同一部分には同一符号を付して重複説明を省略する。 Embodiment 2. FIG.
FIG. 3 is a block diagram showing the configuration of the broadcast content recording apparatus according to the second embodiment, where the length of the received signal is unknown such as news, and the length of the music and reception of the music like music. An analog audio level detector 11 that detects the audio level of the analog signal output from the D / A converter 5 is configured to cope with the case where the elapsed time from the start to the reception stop instruction cannot be obtained. If it is equal to or less than a preset analog audio level value, it is determined that there is no sound, that is, it is determined that the received signal is terminated, and the determination result is notified to the microcomputer 9. In addition, since the other structure is the same as FIG. 1, the same code | symbol is attached | subjected to the same part and duplication description is abbreviate | omitted.

次に動作を説明する。受信信号をスピーカ７に供給して音声出力したり、ＨＤＤ４に供給して録音する動作は実施の形態１と同様であるので、重複説明を省略する。そして、ＨＤＤ４に対する録音状態において、ＡＣＣをオフ状態にした場合の動作を図４のフローチャーチについて説明する。マイクロコンピュータ９はＡＣＣ信号のオフ指示を受けると（ステップＳＴ２１）、録音中か否かを判断する（ステップＳＴ２２）。そして、録音中でなければ直ちにスイッチ８をオフするが、録音中のときは、信号処理部３との間で通信を行い、受信信号とともに送られてくる受信信号が楽曲の場合は実施の形態１で説明したように、その受信信号とともに放送される楽曲の長さ時間−該楽曲の受信開始から受信停止指示までの経過時間＝残り時間が「０」であるかを判断し（ステップＳＴ２３）、楽曲の残り時間が「０」であればスイッチ８をオフする（ステップＳＴ２４）。   Next, the operation will be described. The operation of supplying the received signal to the speaker 7 to output the sound or supplying the received signal to the HDD 4 for recording is the same as that of the first embodiment, and thus the duplicated explanation is omitted. The operation when the ACC is turned off in the recording state with respect to the HDD 4 will be described with reference to the flowchart of FIG. When the microcomputer 9 receives an instruction to turn off the ACC signal (step ST21), it determines whether recording is in progress (step ST22). Then, the switch 8 is immediately turned off when recording is not in progress. However, when recording is in progress, communication is performed with the signal processing unit 3, and the received signal sent together with the received signal is a music. 1, it is determined whether the length time of the music broadcast together with the received signal−the elapsed time from the reception start of the music to the reception stop instruction = the remaining time is “0” (step ST23). If the remaining time of the music is “0”, the switch 8 is turned off (step ST24).

一方、ニュース等のように受信信号の長さが不明な場合は、受信信号の残り時間を演算できない。そこで、アナログ音声レベル検出器１１はＤ／Ａコンバータ５から出力されたアナログ音声レベルが予め設定したアナログ音声レベル値以下であるかを判断し（ステップＳＴ２５）、アナログ音声レベル値以下の状態が所定時間継続したかを判断したときは、マイクロコンピュータ９に対し受信信号が途切れことを通知する。   On the other hand, when the length of the received signal is unknown, such as in news, the remaining time of the received signal cannot be calculated. Therefore, the analog audio level detector 11 determines whether the analog audio level output from the D / A converter 5 is less than or equal to a preset analog audio level value (step ST25), and the state below the analog audio level value is predetermined. When it is determined whether the time has continued, the microcomputer 9 is notified that the received signal is interrupted.

マイクロコンピュータ９はアナログ音声レベル検出器１１から受信信号が途切れた通知を受けるとスイッチ８をオフする。従って，受信信号が楽曲の場合のような楽曲の残り時間を演算できる受信信号の場合は勿論、ニュース等のように受信信号の長さが不明な受信信号であっても、ユーザは録音操作に気を使うことなく、いつスイッチオフの指示を行っても、その受信信号を尻切れ等を生ずることなく、最後まで確実に録音することができる。   When the microcomputer 9 receives a notification that the reception signal is interrupted from the analog audio level detector 11, the microcomputer 9 turns off the switch 8. Therefore, the user can perform the recording operation even in the case of a received signal whose length of the received signal is unknown, such as news, as well as the received signal that can calculate the remaining time of the music as in the case of the music. Regardless of care, whenever a switch-off instruction is given, the received signal can be reliably recorded to the end without causing a shortage or the like.

実施の形態３．
図５は実施の形態３である放送内容録音装置の構成を示すブロック図であり、実施の形態２と同様、ニュース等のように受信信号の長さが不明な場合に対応する構成図である。信号処理部３から出力されたデジタル信号の音声レベルを検出するデジタル音声レベル検出器１２を備え、ｎビットからなるデジタル信号の全てのビットが「０」となり、この「０」状態が所定時間継続すると、無音と判断、つまり、受信信号の終了と判断して、その判断結果をマイクロコンピュータ９に通知する構成である。なお、他の構成は図１と同一であるから、同一部分には同一符号を付して重複説明を省略する。 Embodiment 3 FIG.
FIG. 5 is a block diagram showing the configuration of the broadcast content recording apparatus according to the third embodiment. Similarly to the second embodiment, FIG. 5 is a configuration diagram corresponding to the case where the length of the received signal is unknown, such as news. . The digital audio level detector 12 for detecting the audio level of the digital signal output from the signal processing unit 3 is provided, and all the bits of the n-bit digital signal become “0”, and this “0” state continues for a predetermined time. Then, it is determined that there is no sound, that is, it is determined that the received signal is terminated, and the determination result is notified to the microcomputer 9. In addition, since the other structure is the same as FIG. 1, the same code | symbol is attached | subjected to the same part and duplication description is abbreviate | omitted.

次に動作を説明する。受信信号をスピーカ７に供給して音声出力したり、ＨＤＤ４に供給して録音する動作は実施の形態１と同様であるので、重複説明を省略する。そして、ＨＤＤ４に対する録音状態において、ＡＣＣをオフ状態にした場合の動作を図６のフローチャートについて説明する。マイクロコンピュータ９はＡＣＣ信号のオフ指示を受けると（ステップＳＴ３１）、録音中か否かを判断する（ステップＳＴ３２）。そして、録音中でなければ直ちにスイッチ８をオフするが、録音中のときは、信号処理部３との間で通信を行い、受信信号とともに送られてくる受信信号が楽曲の場合は実施の形態１で説明したように、その受信信号とともに放送される楽曲の長さ時間−該楽曲の受信開始から受信停止指示までの経過時間＝残り時間が「０」であるかを判断し（ステップＳＴ３３）、楽曲の残り時間が「０」であればスイッチ８をオフする（ステップＳＴ３４）。   Next, the operation will be described. The operation of supplying the received signal to the speaker 7 to output the sound or supplying the received signal to the HDD 4 for recording is the same as that of the first embodiment, and thus the duplicated explanation is omitted. The operation when the ACC is turned off in the recording state with respect to the HDD 4 will be described with reference to the flowchart of FIG. When receiving an instruction to turn off the ACC signal (step ST31), the microcomputer 9 determines whether recording is in progress (step ST32). The switch 8 is immediately turned off when recording is not in progress. However, when recording is in progress, communication is performed with the signal processing unit 3, and the received signal sent together with the received signal is a music. 1, it is determined whether the length time of the music broadcast together with the received signal−the elapsed time from the reception start of the music to the reception stop instruction = the remaining time is “0” (step ST33). If the remaining time of the music is “0”, the switch 8 is turned off (step ST34).

一方、ニュース等のように受信信号の長さが不明な場合は、デジタル音声レベル検出器１２により、信号処理部３から出力されたｎビットからなるデジタル信号の全てのビットが「０」となり、この「０」状態が所定時間継続したかを判断し（ステップＳＴ３５）、デジタル信号の全てのビットが「０」となり、この「０」状態が所定時間継続したと判断したときは、マイクロコンピュータ９に対し無音状態、つまり受信信号が途切れたことを通知する。   On the other hand, when the length of the received signal is unknown, such as in news, all the bits of the n-bit digital signal output from the signal processing unit 3 are “0” by the digital audio level detector 12. It is determined whether this "0" state has continued for a predetermined time (step ST35). When all the bits of the digital signal are "0", and it is determined that this "0" state has continued for a predetermined time, the microcomputer 9 Is notified that there is no sound, that is, the received signal is interrupted.

マイクロコンピュータ９はデジタル音声レベル検出器１２から受信信号が途切れた通知を受けるとスイッチ８をオフする。従って，残り時間が演算できる楽曲のような受信信号は勿論、残り時間が演算できないニュース等のように受信信号の長さ時間が不明な受信信号であっても、ユーザは録音操作に気を使うことなく、いつスイッチオフの指示を行っても、その受信信号を尻切れ等を生ずることなく、最後まで確実に録音することができる。   When the microcomputer 9 receives notification from the digital audio level detector 12 that the received signal is interrupted, the microcomputer 8 turns off the switch 8. Therefore, the user pays attention to the recording operation even for a received signal whose remaining time is unknown, such as news that the remaining time cannot be calculated, as well as a received signal that can calculate the remaining time. Even when a switch-off instruction is given at any time, the received signal can be surely recorded to the end without causing a shortage.

実施の形態４．
図７は実施の形態４である放送内容録音装置の構成を示すブロック図であり、ＨＤＤ４に対する録音する場合の変形例を示すもので、Ｄ／Ａ（デジタル／アナログ）コンバータ５とＨＤＤ４との接続路にＭＰＥＧエンコーダ１３を、また、ＨＤＤ４とアンプ６との接続路にＭＰＥＧデコーダ１４を設けたもので、他の構成は図１に示す実施の形態１と同一構成であるから同一部分に同一符号を付して重複説明を省略する。 Embodiment 4 FIG.
FIG. 7 is a block diagram showing the configuration of the broadcast content recording apparatus according to the fourth embodiment, and shows a modified example in the case of recording on the HDD 4. Connection between the D / A (digital / analog) converter 5 and the HDD 4 is shown. The MPEG encoder 13 is provided on the path, and the MPEG decoder 14 is provided on the connection path between the HDD 4 and the amplifier 6. The other configurations are the same as those in the first embodiment shown in FIG. A duplicate description is omitted.

この実施の形態４では、ＨＤＤ４に対して情報を圧縮して記憶し、ＨＤＤ４から読み出した情報は拡張してアンプ６に供給するので、ＨＤＤ４の記憶量を増すことができるとともに、受信信号の出力には何等の不都合も生じないものである。
なお、上記の各実施の形態では、記憶媒体としてＨＤＤを例示したが、このＨＤＤに限定されるものではなく、ＣＤＲ、フラッシュメモリ等であっても同様である。
また、図示例は、車に搭載したデジタル受信装置で受信した受信信号を録音する場合を例について説明したが、室内に設置した固定式のデジタル受信装置で受信した受信信号を録音する場合についても同様に適用することができる。 In the fourth embodiment, the information is compressed and stored in the HDD 4, and the information read from the HDD 4 is expanded and supplied to the amplifier 6. Therefore, the storage amount of the HDD 4 can be increased and the reception signal is output. There is no inconvenience.
In each of the above embodiments, the HDD is exemplified as the storage medium. However, the present invention is not limited to this HDD, and the same applies to a CDR, a flash memory, or the like.
Moreover, although the example of illustration demonstrated the example when recording the received signal received with the digital receiver installed in the car, also when recording the received signal received with the fixed digital receiver installed indoors The same can be applied.
