Title
(JA) デジタルケーブルテレビジョン機器の検査方法及び自己検査ケーブルテレビジョン機器
Abstract
(JA)

本発明の一実施の形態であるケーブルテレビジョン機器を検査する検査方法は、検査をトリガするイベントを検出するステップと、許可された設置場所におけるケーブルテレビジョンネットワーク特性の関数であるフィンガプリント値を生成するステップと、フィンガプリント値を保存された基準値と照合するステップと、フィンガプリント値が保存された基準値の指定された範囲内にある場合、ケーブルテレビジョン機器が標準動作を実行することを許可するステップと、フィンガプリント値が保存された基準値の指定された範囲外にある場合、ケーブルテレビジョン機器が標準動作を実行することを禁止するステップとを有する。他の実施形態では、本発明から逸脱することなく、これらの特徴を変更でき、本要約は、本発明を限定するものではない。
