Title: マルチメディアストリームの合成
IPC: H04N7/173
Filed: 2009-03-13
Abstract: 高品質映像ストリーム及び低品質映像ストリームを含む２以上の映像ストリームは、無線ネットワークを介して映像受信機器に同時送信される。映像ストリームの全ては、同一の映像コンテンツであるが、異なる映像品質を有する。高品質映像ストリームは、第１の成分（例えば高周波数成分）が第２の成分（例えば低周波数成分）よりも高いレベルの誤り保護を受けるように、不均一誤り保護符号を用いて符号化される。映像受信機器は、チャネル状態が好適である場合に、高品質映像ストリームを選択できる。チャネル状態が高品質映像ストリームをサポートするために十分でない場合、映像受信機器は、高い誤り保護を有する高品質映像ストリームの第１の成分が使用可能であるか否かを判断する。使用可能である場合、映像受信機器は高品質映像ストリームの第１の成分と低品質映像ストリームとを合成する。使用不可能である場合、映像受信機器は低品質映像ストリームを出力する。 【選択図】図１
