Scramble (English spelling)

Japanese: スクランブル(英語表記)scramble
Scramble (English spelling)
To ensure confidentiality in pay-per-view broadcasts, video and audio signals are electrically scrambled using a special device called an encoder. Conversely, descrambling refers to restoring the original signals using a device called a decoder. If a scrambled signal is viewed without a decoder, the screen will appear scrambled. Only those who have signed a reception contract with the broadcasting company can install a decoder and view the signal normally. Scrambling methods range from simple ones that process synchronization signals to prevent the television receiver from synchronizing, to ones that use digital technology to change the order of image signals based on a code.

有料放送で秘匿性をもたせるため,映像信号や音声信号をエンコーダと呼ばれる特殊な装置で電気的に攪拌すること。逆にデコーダと呼ばれる装置で元の信号に復元することをデスクランブルという。スクランブルのかけられた信号をデコーダを用いないで見ると,画面がかき乱されたようになる。放送事業者と受信契約をした者のみがデコーダを設置し,正常に視聴できる。スクランブルの方式には,同期信号を加工してテレビ受像機の同期をかからなくする簡易なものから,デジタル技術を駆使して暗号に基づき画像信号の順序を変えるものなどがある。
