　かかる構成のテレビ受像機においては、上記の主電源スイッチ及びテレビ電源スイッチが共にオン状態にあるときには、操作部１８からチャンネル選択指令が主制御部１７に供給されると、主制御部１７はチャンネル選択指令に応じてチューナ部１１の受信チャンネルを設定する。チューナ部１１では受信チャンネルのテレビ放送信号が受信され、そのテレビ放送信号は映像／音声再生系１２に供給され、映像／音声再生系１２によって復号化されて映像信号及び音声信号が生成される。生成された映像信号は表示出力部１３に供給される。この結果、その映像信号が示す映像、すなわち受信チャンネルの映像が主表示器１９の表示画面１９ａに表示される。 In the television receiver having such a configuration, when both the main power switch and the television power switch are in the ON state, when a channel selection command is supplied from the operation unit 18 to the main control unit 17, the main control unit 17 The reception channel of the tuner unit 11 is set according to the selection command. The tuner unit 11 receives a television broadcast signal of a reception channel, and the television broadcast signal is supplied to the video / audio reproduction system 12 and is decoded by the video / audio reproduction system 12 to generate a video signal and an audio signal. The generated video signal is supplied to the display output unit 13. As a result, the video indicated by the video signal, that is, the video of the reception channel is displayed on the display screen 19 a of the main display 19.
　このようにテレビ放送の受信チャンネルの映像が主表示器１９に表示されている状態においては、図３に示すように、主制御部１７は受信チャンネルの現在の番組についてのＥＰＧデータをメモリ１６からデータ取得部１５から読み出す（ステップＳ１）。読み出したＥＰＧデータは副制御部２１に供給される（ステップＳ２）。ＥＰＧデータはチャンネル番号、放送局名、番組名、ジャンル、放送時間、出演者、内容（あらすじ）等の番組情報を含んでいる。副制御部２１はＥＰＧデータに応じて表示データを作成し、その表示データを表示出力部２２に供給する（ステップＳ３）。表示出力部２２は表示データに応じて副表示器２３を駆動するので、副表示器２３の表示画面２３ａには現受信チャンネルにおける放送番組の番組情報が表示される（ステップＳ４）。放送番組の番組情報は例えば、図４に示すように、表示される。また、その番組情報は自動スクロールで表示され、更に、複数回繰り返しで表示される。 Thus, in the state where the video of the reception channel of the television broadcast is displayed on the main display 19, the main control unit 17 stores the EPG data for the current program of the reception channel from the memory 16, as shown in FIG. Read from the data acquisition unit 15 (step S1). The read EPG data is supplied to the sub-control unit 21 (step S2). The EPG data includes program information such as a channel number, a broadcasting station name, a program name, a genre, a broadcasting time, a performer, and a content (summary). The sub-control unit 21 creates display data according to the EPG data, and supplies the display data to the display output unit 22 (step S3). Since the display output unit 22 drives the sub display 23 in accordance with the display data, the program information of the broadcast program in the current reception channel is displayed on the display screen 23a of the sub display 23 (step S4). For example, the program information of the broadcast program is displayed as shown in FIG. Further, the program information is displayed by automatic scrolling, and is further repeatedly displayed a plurality of times.
　よって、主表示器１９の表示画面１９ａに映像表示中の放送番組の番組情報が主表示器１９とは別の副表示器２３の表示画面２３ａに表示されるので、ユーザは主表示器１９の表示画面１９ａに表示中の番組映像を視認することができ、更に、その番組映像を妨げることなく番組情報を視認することができる。 Therefore, since the program information of the broadcast program being displayed on the display screen 19a of the main display 19 is displayed on the display screen 23a of the sub display 23 different from the main display 19, the user can The program video being displayed on the display screen 19a can be viewed, and the program information can be viewed without interfering with the program video.
　次に、主電源スイッチがオン状態にあり、テレビ電源スイッチがオフであるときにユーザがこのテレビ受像機に接近して人感センサ２４が人の存在を検知した場合の動作について説明する。 Next, the operation when the user approaches the television receiver and the human sensor 24 detects the presence of a person when the main power switch is on and the television power switch is off will be described.
　図５に示すように、副制御部２１は、人感センサ２４による人検知出力に応答して表示出力部２２及び副表示器２３各々に電源部３から電源電圧を供給し（ステップＳ１１）、主制御部１７に対して現在放送中の番組及び次の時間帯の放送番組についてのＥＰＧデータを主制御部１７に対して要求する（ステップＳ１２）。 As shown in FIG. 5, the sub control unit 21 supplies the power supply voltage from the power supply unit 3 to each of the display output unit 22 and the sub display 23 in response to the human detection output from the human sensor 24 (step S11). The main control unit 17 is requested to the main control unit 17 for EPG data regarding the program currently being broadcast and the broadcast program in the next time zone (step S12).
　主制御部１７は、副制御部２１からＥＰＧデータの要求を受信すると、少なくともデータ取得部１５及びメモリ１６に電源部３から電源電圧を供給し（ステップＳ１３）、現在放送中の番組及び次の時間帯の放送番組についてのＥＰＧデータをデータ取得部１５を介してメモリ１６から読み出す（ステップＳ１４）。なお、メモリ１６に必要なＥＰＧデータが全て保存されていない場合には、チューナ部１１又は回線インタフェース部１４に電源部３からの電源電圧を供給して必要なＥＰＧデータを外部から受信することが行われる。 When the main control unit 17 receives a request for EPG data from the sub control unit 21, the main control unit 17 supplies the power supply voltage from at least the data acquisition unit 15 and the memory 16 from the power supply unit 3 (step S13). The EPG data for the broadcast program in the time zone is read out from the memory 16 via the data acquisition unit 15 (step S14).

As described above, the EPG data includes program information such as a channel number, a broadcasting station name, a program name, a genre, a broadcasting time, and performers. The sub-control unit 21 creates display data according to the EPG data, and supplies the display data to the display output unit 22 (step S16). Since the display output unit 22 drives the sub-display 23 in accordance with the display data, the program information of the program currently being broadcast and the broadcast program in the next time zone is displayed on the display surface of the sub-display 23 (step S17). Thus, even if the TV power switch is turned on and no video is displayed on the main display 19, the program information can be viewed. At this time, since the main display 19 is not displaying, the TV power switch is operated when the user wants to watch the TV according to the program information displayed on the sub-display 23. Steps S12 to S17 are repeated every predetermined time.
　副制御部２１は、人感センサ２４による人検知出力に応答した後においては、図６に示すように、人感センサ２４による人検知出力があるか否かを判別し（ステップＳ２１）、人検知出力がない状態が所定時間以上継続すると（ステップＳ２２）、表示出力部２２及び副表示器２３各々への電源部３からの電源電圧供給を停止し（ステップＳ２３）、更に、主制御部１７に対して副表示が終了したことを通知する（ステップＳ２４）。主制御部１７は副表示終了通知に応じてデータ取得部１５及びメモリ１６各々への電源部３からの電源電圧供給を停止する（ステップＳ２５）。チューナ部１１又は回線インタフェース部１４への電源部３からの電源電圧供給が行われている場合にはステップＳ２３ではその電源電圧供給を停止することが行われる。 After responding to the human detection output from the human sensor 24, the sub-control unit 21 determines whether there is a human detection output from the human sensor 24 as shown in FIG. 6 (step S21). When the state in which there is no detection output continues for a predetermined time or longer (step S22), the supply of the power supply voltage from the power supply unit 3 to each of the display output unit 22 and the sub-display 23 is stopped (step S23). Is notified that the sub-display has been completed (step S24). The main control unit 17 stops the supply of the power supply voltage from the power supply unit 3 to each of the data acquisition unit 15 and the memory 16 in response to the sub display end notification (step S25). When the power supply voltage is supplied from the power supply unit 3 to the tuner unit 11 or the line interface unit 14, the supply of the power supply voltage is stopped in step S23.
　なお、上記した実施例においては、人感センサ２４が人の存在を検知した場合の動作について説明したが、タッチセンサ２５のタッチ部に人が接触したことを検知した場合に副表示器２３には現在放送中の番組及び次の時間帯の放送番組の番組情報が表示されるようにしても良い。また、副表示器２３には番組情報だけでなくニュースや時刻が表示されるようにしても良い。更に、副表示器２３に番組情報が自動表示されたことをユーザに知らせるために音声出力を発しても良い。 In the above-described embodiment, the operation when the human sensor 24 detects the presence of a person has been described. However, when it is detected that a person has touched the touch portion of the touch sensor 25, the sub-display 23 is displayed.
