放送受信端末及びその選局方式

Abstract

【課題】テレビやラジオ等の放送を受信する受信機能を有し、人が携帯する、もしくは車等で移動する放送受信端末において、受信状態が変化する場合でも、簡単な選局操作によって受信可能かつ受信感度の良い放送を容易に選択する選局方式を提供すること。 【解決手段】放送波状態取得手段により受信可能な放送波の物理チャンネル及び、該物理チャンネルの受信感度レベルを取得し、選局リストを生成/更新する。使用者からの選局指示があった場合、放送波選択手段により選局リストから受信感度レベルの良い放送波のみ選択対象として扱い、受信する放送波を選択する。 【選択図】図3
PROBLEM TO BE SOLVED: To provide a tuning method for a broadcast receiving terminal having a function of receiving broadcast by television, radio or the like and carried by a person or moved by a car or the like by which airwaves receivable with a high reception sensitivity can be easily tuned by a simple tuning operation even when reception condition changes. SOLUTION: Physical channels of receivable broadcast waves and the reception sensitivity level of each of the physical channels are obtained by a broadcast wave condition acquisition means and a channel selection list is created/updated. When channel selection is instructed by a user, only broadcast waves with high levels of reception sensitivity are treated as objects of selection from the channel selection list by a broadcast wave selection means and a broadcast wave to be received is selected.
