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、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、簡易相互認証をする機能、改竄防止をする機能、簡易証明をする機能およびセキュリティ通信の通信状態を検出する機能を含む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設けられた光源の輝度若しくは色を変化させることにより表示させ、
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、前記全画面表示上に重ねてエラーの要因を示すエラーメッセージを表示させる受信機が提供される。 According to an 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 a broadcast wave received by the receiving unit and outputs a video signal, A display control unit that causes the video signal output by the processing unit to be displayed on a full screen on a display screen of a display, and a receiver including a communication unit,
A security operation detecting unit including a function for performing simple mutual authentication, a function for preventing falsification, a function for performing simple certification, and a function for detecting a communication state of security communication based on transport layer security (TLS) via the communication unit. have a,
The display control unit further includes:
The communication state detected by the security operation detection unit, when the security communication is being performed, in a state where the video signal is displayed on the display screen of the display device in full screen,
Display by changing the brightness or color of a light source provided in a frame located around the display screen so that the display that the security communication is being performed does not overlap the full screen display,
Further, when the communication state detected by the security operation detection unit is a state in which an error has occurred during execution of the security communication, an error message indicating a cause of the error is displayed on the full screen display. A receiver is provided.
