Description
(1)アプリケーションの終了時間Yを考慮し、X+Y秒前に選局を開始する。
(2)X+Y秒前にアプリケーションが起動しているかどうかを確認し、共有資源がアプリケーションに使用されている場合にはX+Y秒前、使用されていなければX秒前に予約選局。これは、予約選局を早くすると、連続予約の場合に前の番組の最後が切れる部分が多くなることを防止する。
尚、本発明は、コンピュータに上記ステップを実行させるためのプログラムであっても良い。
1)番組開始時間の確認を確実に行うことができる。
2)メモリの有効活用が可能である。
3)連続予約時に前予約番組の最後が切れるところを減らすことができる。
Claims (2)
- 予約されている番組の開始時間より前にEITに基づく番組放送時刻の遅延の有無を評価し、番組開始時間に追従して動作する予約機能を有し、さらにTV機能を満たすための第1のアプリケーションとTV機能を満たすためのアプリケーション以外の第2のアプリケーションとが、一部、または全部のハードウェア資源を共有するため、前記それぞれのアプリケーションを排他的に利用可能なデジタル放送受信装置において、
該第2のアプリケーションが共有資源の解放に必要となる終了に要する時間Yを、EITの受信に必要な時間Xに対して加算した時間X+Yだけ予約した番組の開始時間より前に、予約チャンネルへの選局を開始して、予約した番組の開始時間までにEITの受信に必要な時間Xの期間だけEITを受信することで、EITに基づく番組放送時刻の遅延の有無の評価に必要なEITの取得を行うことを特徴とするデジタル放送受信装置。 - 予約されている番組の開始時間より前にEITに基づく番組放送時刻の遅延の有無を評価し、番組予約開始時間に追従して動作する予約機能を有し、さらにTV機能を満たすための第1のアプリケーションとTV機能を満たすためのアプリケーション以外の第2のアプリケーションとが、一部、または全部のハードウェア資源を共有するため、前記それぞれのアプリケーションを排他的に利用可能なデジタル放送受信装置において、
