Abrégé
(JA)

テレビ広告自動検出装置であって、テレビが受信した、第1組のビデオフレームと、画面切換え周波数が前記第1組のビデオフレームと顕著に異なる第2組のビデオフレームと、を記憶するビデオフレームバッファと、前記ビデオフレームバッファに記憶されている前記第1組と前記第2組のビデオフレームを読取って、前記第1組のビデオフレームが前記第2組のビデオフレームに切換える前の前記第1組のビデオフレームにおいて最後の一つのフレームを計算して、提示キーフレームにし、また新たに受信したビデオフレームと前記提示キーフレームとの間の関連性を計算するビデオ画面切換え検出計算装置と、前記ビデオ画面切換え検出計算装置が、前記新たに受信したビデオフレームと前記提示キーフレームとの間の関連性が予め定めた閾値より大きい又は等しいと検出された場合、提示信号を発生する提示信号発生装置と、前記ビデオ画面切換え検出計算装置の読み取り、計算操作を制御する制御装置と、を備えることを特徴とするテレビ広告自動検出装置を公開する。その他、テレビ広告自動検出方法も公開する。
