Description
本願は、2003年8月29日に出願された「配信メッセージ管理システム」とする、ワイマン・ラム他の米国特許出願第60/498,575号に基づく優先権を主張するものであり、該出願を本明細書に援用する。
ターゲットコンテンツサーバシステムには、ターゲットコンテンツパケットを準備し、一つ以上のクライアント装置へターゲットコンテンツを放送するためのすべてのコンポーネントが組み込まれている。ターゲットコンテンツサーバシステムには、コンテンツプロバイダからコンテンツを受信するためのコンテンツプロバイダアプリケーション、ターゲットコンテンツパケットを準備するためのターゲットコンテンツサーバおよび放送ストリーム内で所定回ターゲットコンテンツを配信する待ち行列システムを組み込むことができる。
「ターゲットパケット」とは、関連データの集合を指す。ターゲットパケットは好適に、同時にあるいは連続して放送ストリームに乗せて送信する。
コンテンツは種々のデータを備える。好適なデータの種類には、表コンテンツ、メッセージコンテンツおよびアプリケーションコンテンツが含まれる。アプリケーションコンテンツにはメッセージを含む。
受信機は放送信号を受信することができる。好適な受信機は、デジタルまたはアナログのテレビジョン信号を受信できる。受信機は、必要に応じてバックチャンネルを含む。バックチャンネルとは、受信機がクライアント装置外にあるその他のシステムに情報を送信する際に使用する通信経路である。このような通信経路には、標準POTS(従来型の音声電話サービス)電話回線および関連モデムを含む。バックチャンネルはさらに同軸ケーブル、光ファイバケーブル、DSL(デジタル加入者線)、ATM(非同期転送モード)またはその他の有線と無線の両通信回線を含むことができる。
ターゲットコンテンツ拡張部は、受信機で受信する放送信号のコンテンツパケットを検出しようとする。好適にターゲットコンテンツ拡張部は、放送されるすべてのチャンネルを聞き取り、エンドユーザが何を視聴していようと、パケットが早急に識別され、処理されるようにする。ターゲットコンテンツ拡張部は、コンテンツパケットがクライアント装置に向けてターゲットされたコンテンツであるか、さらに処理が必要かどうかを判断するためにフィルタリングを行う。フィルタリングは、ハードウェア(例えば、フィルタはデマルチプレクサ内に設けてもよい)、ソフトウェアまたは両方によるフィルタリングであってもよい。クライアント装置ユーザには、ターゲットコンテンツの取得が全く不要な場合、好適には、このフィルタリングを止めることができる。
