Description

実施形態によれば、映像ストリーム、音声ストリーム、データ放送ストリームを含む放送波を受信する受信部と、前記受信部によって受信された放送波を処理して映像信号を出力するコンテンツ処理部と、前記コンテンツ処理部によって出力された前記映像信号を表示器の表示画面に全画面表示させる表示制御部と、通信部とを備えた受信機であって、
前記通信部を介してトランスポートレイヤーセキュリティ（ＴＬＳ）に基づく、セキュリティ通信の通信状態を検出するセキュリティ動作検出部を有し、
前記表示制御部は更に、
前記セキュリティ動作検出部によって検出された前記通信状態が、前記セキュリティ通信の実行中であった場合、前記表示器の表示画面に前記映像信号を全画面表示させた状態で、前記セキュリティ通信が実行中であることの表示を前記全画面表示に重ならないように、前記表示画面の周囲に位置するフレームに表示させ、
さらに前記セキュリティ動作検出部によって検出された前記通信状態が、前記セキュリティ通信の実行中にエラーが発生した状態であった場合、
エラーの要因が、ルート証明書自体が受信機側にない場合は、受信機側にルート証明書が存在していないためセキュリティ通信を実行できない旨を、前記全画面表示上に重ねて表示させ、
前記エラーの要因が、サーバ証明書の共通名不一致の場合、接続先の証明書には表示しようとしているページの名前が含まれていなく、接続先の安全性が確認できないために接続できない旨を、前記全画面表示上に重ねて表示させる
前記エラーの要因が、受信機側でルート証明書を無効設定している場合は、受信機のルート証明書が無効に設定されているためセキュリティ通信を実行できない旨を、前記全画面表示上に重ねて表示させる受信機である。 According to the embodiment, a receiving unit that receives a broadcast wave including a video stream, an audio stream, and a data broadcast stream, a content processing unit that processes the broadcast wave received by the receiving unit and outputs a video signal, A display control unit that displays the video signal output by the content processing unit on a display screen of a display device on a full screen;
Based on Transport Layer Security (TLS) via the communication unit, a security operation detection unit that detects a communication state of security communication ,
The display control unit further includes
When the communication state detected by the security operation detection unit is executing the security communication, the security communication is being executed with the video signal displayed on the full screen on the display screen of the display unit. So that the display indicating that it is not overlapped with the full-screen display is displayed in a frame located around the display screen,
Further, when the communication state detected by the security operation detection unit is a state where an error has occurred during execution of the security communication,
If the cause of the error is that the root certificate itself is not on the receiver side, the fact that the root certificate does not exist on the receiver side and security communication cannot be executed is displayed over the full screen display,
If the cause of the error is a mismatch in the common name of the server certificate, the connection destination certificate does not contain the name of the page to be displayed, and the connection destination cannot be confirmed and the connection cannot be confirmed. , Overlaid on the full screen display
If the cause of the error is that the root certificate is set to be invalid on the receiver side, the fact that the root certificate of the receiver is set to invalid and security communication cannot be executed is displayed on the full screen display. It is a receiver that displays in a superimposed manner.

Claims

A reception unit that receives broadcast waves including a video stream, an audio stream, and a data broadcast stream, a content processing unit that processes the broadcast waves received by the reception unit and outputs a video signal, and an output from the content processing unit A display control unit for displaying the video signal on a display screen of a display device on a full screen, and a communication unit;
Based on Transport Layer Security (TLS) via the communication unit, a security operation detection unit that detects a communication state of security communication ,
The display control unit further includes
When the communication state detected by the security operation detection unit is executing the security communication, the security communication is being executed with the video signal displayed on the full screen on the display screen of the display unit. So that the display indicating that it is not overlapped with the full-screen display is displayed in a frame located around the display screen,
Further, when the communication state detected by the security operation detection unit is a state where an error has occurred during execution of the security communication,
If the cause of the error is that the root certificate itself is not on the receiver side, the fact that the root certificate does not exist on the receiver side and security communication cannot be executed is displayed over the full screen display,
If the cause of the error is a mismatch in the common name of the server certificate, the connection destination certificate does not contain the name of the page to be displayed, and the connection destination cannot be confirmed and the connection cannot be confirmed. , Overlaid on the full screen display
If the cause of the error is that the root certificate is set to be invalid on the receiver side, the fact that the root certificate of the receiver is set to invalid and security communication cannot be executed is displayed on the full screen display. A receiver that displays in a superimposed manner .
