Title
(JA) 符号化されたプリアンブルを用いたデータストリームの識別及び取扱い
Abstract
(JA)

本発明の実施形態は、符号化されたプリアンブルを使用したデータストリームの識別及び取扱い全般に係る。一実施形態に係る装置は、通信チャネルを有するインタフェースと、そのインタフェースと連結されてそのインタフェースを介して1つ以上のデータストリームを送信する送信機と、処理要素とを備え、処理要素は1つ以上の送信用データストリームを受信する。処理要素は、第1種別のデータの送信用の第1データストリーム及び第2データストリームを含む第1種別のデータの送信用データストリームを複数受信すると、第1データストリームに対しては第1プリアンブルを選択し、第2データストリームに対しては第2プリアンブルを選択し、第1プリアンブルは第2プリアンブルとは異なるよう構成される。
