Claims (9)
- 符号化ビデオビットストリームからIフレームを生成する生成手段と、
各Iフレームを複数のモザイクウィンドウのうちの一つに収容する収容手段と、
前記複数のモザイクウィンドウをモザイクビデオフレームに統合する統合手段と、
を具備する、モザイク番組案内生成装置であって、
前記生成手段は、符号化ビデオビットストリームからIフレーム、Pフレーム、Bフレームを検出するフレーム検出器を含み、
前記統合手段は、通常動作において、単一の番組に属するIフレーム、Pフレーム、Bフレームから主番組画像ビデオ信号を生成するウィンドウコンポーザを含み、
前記収容手段は、モザイク動作において、前記生成手段に、PフレームおよびBフレームを無視し、モザイクモード信号を動き補償器に送って動き補償を停止させ、受信された再構成された画素を無効にするため、アンカーフレーム記憶装置にモザイクモード信号を送り、前記ウィンドウコンポーザにモザイクモードで1つのモザイクウィンドウに異なる番組のIフレームをスケーリングするように指令するビデオコントローラを含むことを特徴とするモザイク番組案内生成装置。 - 前記生成手段は、通常動作では、Iフレームの場合にはIフレームを含み、PフレームまたはBフレームの場合には画素予測誤差による画素を含み、モザイク動作ではIフレームのみを含む画素データを生成する、可変長デコーダ、逆量子化器、逆離散コサイン変換器を備えることを特徴とする請求項1に記載のモザイク番組案内生成装置。
- 前記モザイク番組案内装置は、混合モードにおいて、選択された番組のPフレームおよびBフレームの復号化を許容し、他のすべての番組のPフレームおよびBフレームの復号化を阻止するように構成され、前記ウィンドウコンポーザは、混合モードでは、1つのモザイクウィンドウを埋めるように、異なる番組の各Iフレームをスケーリングし、完全に復号化されたビデオプログラムを主ウィンドウに適合するようにスケーリングするように構成されたことを特徴とする請求項1または2に記載のモザイク番組案内生成装置。
- 前記主ウィンドウは、通常レートでリフレッシュされ、前記モザイクウィンドウは、前記通常レートよりも遅くリフレッシュされることを特徴とする請求項3に記載のモザイク番組案内生成装置。
- 請求項1、2、4のいずれかに記載のモザイク番組案内生成装置を含み、符号化ビットストリームを生成するチューナおよび復調器をさらに備えた受信機。
- 前記符号化ビットストリームを受け取り、符号化されたオーディオビットストリームおよび符号化ビデオビットストリームを生成するデデマルチプレクサおよび暗号解読器をさらに備えた請求項5に記載の受信機。
- 符号化ビデオビットストリームからIフレームを生成するステップと、
各Iフレームを複数のモザイクウィンドウのうちの一つに収容するステップと、
前記複数のモザイクウィンドウをモザイクビデオフレームに統合するステップと、
を含み、
前記生成するステップは、符号化ビデオビットストリームからIフレーム、Pフレーム、Bフレームを検出することを含み、
前記統合するステップは、通常動作において、単一の番組に属するIフレーム、Pフレーム、Bフレームから主番組画像ビデオ信号を生成することを含み、
前記収容するステップは、モザイク動作において、前記生成手段に、PフレームおよびBフレームを無視し、動き補償を停止させ、受信された再構成された画素を無効にし、モザイクモードで1つのモザイクウィンドウに異なる番組のIフレームを埋めるようにスケーリングすることを含む、モザイク番組案内生成方法。 - 前記発生するステップは、混合モードでは、選択された番組のPフレームおよびBフレームの復号化を許容し、他のすべての番組のPフレームおよびBフレームの復号化を阻止するようにし、前記統合するステップは、混合モードでは、1つのモザイクウィンドウを埋めるように、異なる番組の各Iフレームをスケーリングし、完全に復号化されたビデオプログラムを主ウィンドウに適合するようにスケーリングするようにすることを特徴とする請求項7に記載のモザイク番組案内生成方法。
- 前記主ウィンドウは、通常レートでリフレッシュされ、前記モザイクウィンドウは、前記通常レートよりも遅くリフレッシュされることを特徴とする請求項8に記載のモザイク番組案内生成方法。
