Description

本発明は映像出力装置に関し、特に、録画機器及びメディア再生機器を内蔵したテレビジョン受信機に関する。   The present invention relates to a video output device, and more particularly to a television receiver incorporating a recording device and a media playback device.

テレビジョン受信機に録画機器及びメディア再生機器を内蔵した場合、チューナ経由の映像表示をする単なるテレビジョン受信機の機能寿命と、内蔵された録画機器及びメディア再生機器の機能寿命及び故障率とは異なる。   When a television receiver has a built-in recording device and media playback device, what is the functional life of a simple television receiver that displays images via a tuner, and what is the functional life and failure rate of the built-in recording device and media playback device? Different.

録画機器及びメディア再生機器は、モータ等の動作する機構部品が使用されているために、モータ等の動作する機構部品がない単なるテレビジョン受信機よりもその機能寿命が短く、故障する確率が高い。   Since recording devices and media playback devices use mechanical parts such as motors, they have a shorter functional life and a higher probability of failure than simple television receivers that do not have mechanical parts such as motors. .

録画機器及びメディア再生機器が故障しても、テレビジョン受信機のみを動作させることは容易に考えられるが、故障原因を明確にしないで故障のまま放置して使用するとき、故障原因が電源関係であった場合には、テレビジョン受信機内の他の機器（特に電源系統）への悪影響が生じる可能性がある。また特許文献１のようにＨＤＤ自体の機能寿命を実質的に延ばすような試みもなされているが、他の機器の機能寿命との均衡を保つのには限界がある。   Even if the recording device and media playback device break down, it is easy to operate only the television receiver. However, if the failure cause is not clarified, the failure cause is related to the power supply. If this is the case, there is a possibility that other devices (particularly the power supply system) in the television receiver will be adversely affected. Although attempts have been made to substantially extend the functional life of the HDD itself as in Patent Document 1, there is a limit to maintaining a balance with the functional life of other devices.

＜Ａ−２．動作＞
図２は、本発明にかかるテレビジョン受信機の動作を示す図である。 <A-2. Operation>
FIG. 2 is a diagram showing the operation of the television receiver according to the present invention.

まず、ステップＳ１においてテレビジョン受信機の電源を入れる。次に、ステップＳ２に移行し、図１における録画機器１およびメディア再生機器２が、マイコン部５と双方向信号１９、２０により通信する信号を確認する。   First, in step S1, the television receiver is turned on. Next, the process proceeds to step S2, and the recording device 1 and the media playback device 2 in FIG. 1 confirm signals that communicate with the microcomputer unit 5 using the bidirectional signals 19 and 20.

ステップＳ２の双方向信号１９、２０において、録画機器１又はメディア再生機器２のエラー又は異常状態を示すエラー信号が含まれていた場合、ステップＳ４の録画機器１又はメディア再生機器２の電圧、電流検出のフローに移行する。   If the bidirectional signals 19 and 20 in step S2 include an error signal indicating an error or abnormal state of the recording device 1 or the media playback device 2, the voltage and current of the recording device 1 or the media playback device 2 in step S4. Move to the detection flow.

ステップＳ２の双方向信号１９、２０において、録画機器１又はメディア再生機器２のエラー又は異常状態を示すエラー信号が含まれていない場合、ステップＳ３に移行し、録画機器１、メディア再生機器２への電源供給を継続し、映像処理回路６において処理された映像を表示パネルであるＬＣＤパネル１０に表示する。   If the bidirectional signals 19 and 20 in step S2 do not include an error signal indicating an error or abnormal state of the recording device 1 or the media playback device 2, the process proceeds to step S3, and the recording device 1 and the media playback device 2 are transferred. The video processing circuit 6 displays the video processed by the video processing circuit 6 on the LCD panel 10 as a display panel.

ステップＳ４おいて、異常状態である録画機器１又はメディア再生機器２の電圧、電流を検出する。録画機器１に関しては、電流測定装置１２、電圧測定装置１３にて電流値、電圧値を検出し、マイコン部５にて、録画機器１の電源ラインの異常状態である電源系異常状態であるか否かを判断する。録画機器１の電源ラインに異常がない（電源系異常状態でない）場合は、ステップＳ５に移行する。録画機器１の電源ラインに異常がある（電源系異常状態である）場合は、ステップＳ７に移行する。メディア再生機器２についても、電流測定装置１５、電圧測定装置１６にて電流値、電圧値を検出し、マイコン部５にて、メディア再生機器２の電源ラインが異常状態である電源系異常状態であるか否かを判断する。メディア再生機器２の電源ラインに異常がない（電源系異常状態でない）場合は、ステップＳ５に移行する。メディア再生機器２の電源ラインに異常がある（電源系異常状態である）場合は、ステップＳ７に移行する。   In step S4, the voltage and current of the recording device 1 or the media playback device 2 in an abnormal state are detected. Regarding the recording device 1, whether the current value and the voltage value are detected by the current measuring device 12 and the voltage measuring device 13, and is the power supply system abnormal state that is the abnormal state of the power line of the recording device 1 detected by the microcomputer unit 5? Judge whether or not. If there is no abnormality in the power supply line of the recording device 1 (the power supply system is not in an abnormal state), the process proceeds to step S5. If there is an abnormality in the power supply line of the recording device 1 (the power supply system is in an abnormal state), the process proceeds to step S7. As for the media playback device 2, the current measurement device 15 and the voltage measurement device 16 detect the current value and the voltage value, and the microcomputer unit 5 detects that the power supply line of the media playback device 2 is in an abnormal state. Judge whether there is. If there is no abnormality in the power supply line of the media playback device 2 (the power supply system is not in an abnormal state), the process proceeds to step S5. If there is an abnormality in the power supply line of the media playback device 2 (the power supply system is in an abnormal state), the process proceeds to step S7.

録画機器１またはメディア再生機器２の電源ラインに異常がある（電源系異常状態）とマイコン部５が判断し、ステップＳ７に移行した場合は、電源系異常状態の録画機器１またはメディア再生機器２の電源回路遮断装置１１、１４を働かせ、録画機器１またはメディア再生機器２の電源を遮断する（次回テレビジョン受信機の電源を入れる際にも、遮断状態を保つ）。電源系異常状態にあった電源ラインの電源遮断状態を維持しながら、再度ステップＳ４において電流測定装置１２、１５及び電圧測定装置１３、１６にて電流値、電圧値を検出し電源系異常状態か否かを判断する。１回目にステップＳ４にて電源系異常状態と判断され電源回路遮断装置１１、１４によって電源回路を遮断されているので、通常ここでは電源系異常状態とは判断されずステップＳ５に移行する。   When the microcomputer unit 5 determines that there is an abnormality in the power supply line of the recording device 1 or the media playback device 2 (power supply system abnormal state) and the process proceeds to step S7, the recording device 1 or the media playback device 2 in the power supply system abnormal state. Are turned off to turn off the recording device 1 or the media playback device 2 (the cut-off state is maintained when the television receiver is turned on next time). While maintaining the power shutoff state of the power supply line that was in the power supply system abnormal state, in step S4, the current measurement devices 12 and 15 and the voltage measurement devices 13 and 16 detect the current value and voltage value to determine whether the power supply system is abnormal Judge whether or not. Since it is determined that the power supply system is abnormal in step S4 for the first time and the power supply circuit is shut off by the power supply circuit disconnecting devices 11 and 14, the power supply system abnormal state is not normally determined here and the process proceeds to step S5.

ステップＳ５では、ステップＳ２にてエラー信号が含まれ、異常状態の録画機器１又はメディア再生機器２があることを使用者に知らしめるために、マイコン部５は、ＬＣＤパネル１０に故障している旨の表示を出す。   In step S5, the microcomputer unit 5 has failed in the LCD panel 10 in order to inform the user that there is an error signal in step S2 and there is an abnormal recording device 1 or media playback device 2. A message to that effect is displayed.

ステップＳ６では、故障していない録画機器１、メディア再生機器２、チューナ７、ＨＤＭＩ８、ビデオ入力９等の映像を、ＬＣＤパネル１０に表示する。   In step S <b> 6, video images such as the recording device 1, the media playback device 2, the tuner 7, HDMI 8, and the video input 9 that are not malfunctioning are displayed on the LCD panel 10.

異常状態である録画機器１又はメディア再生機器２をステップＳ５にて通知したにもかかわらず操作した場合には、再度ステップＳ５に戻り、マイコン部５はＬＣＤパネル１０に故障している旨の表示を出す。   If the recording device 1 or the media playback device 2 in the abnormal state is operated in spite of the notification in step S5, the process returns to step S5 again, and the microcomputer unit 5 indicates that the LCD panel 10 has failed. Put out.

電源系異常状態の録画機器１、メディア再生機器２のそれぞれへの電源供給を遮断し、その他の故障していない機器を使用できるようにしているのは、機能寿命の短い機器により、すべての機器を使用できなくするのは使用者にとって不利益であるからである。   The power supply to the recording device 1 and the media playback device 2 in an abnormal state of the power supply system is cut off so that other devices that are not malfunctioning can be used. This is because it is detrimental to the user to make it unusable.

なお、録画機器１、メディア再生機器２の電源系異常状態での判断だけでなく、信号不良である異常状態の段階でもこれらの機器への電源供給を遮断することも可能である。すなわち、エラー信号が含まれていた場合、異常状態の機器の電流および電圧状態の検出に関わらず、電源供給を遮断することも可能である。ただ、メディア不良、ＨＤＤのセクター不良等の一部の不良の可能性もあり、たまたま信号系統の不良が発生した可能性もある。そのような場合には使用中止にする必要がないので、信号不良である異常状態の段階で使用者がすぐに録画機器１、メディア再生機器２を使用できなくなってしまうことは望ましくはない。   Note that it is possible not only to determine whether the recording device 1 and the media playback device 2 are in the power supply system abnormal state, but also to cut off the power supply to these devices even in the abnormal state where the signal is defective. That is, when an error signal is included, the power supply can be cut off regardless of the detection of the current and voltage state of the abnormal device. However, there may be some failures such as media failure and HDD sector failure, and it may happen that a signal system failure occurred. In such a case, it is not necessary to stop the use, and it is not desirable that the user cannot immediately use the recording device 1 and the media playback device 2 in the abnormal state where the signal is defective.
