Description
つまり、「HTTP://」等、URLを生成するために必須の要素情報については、予め記憶部14に記憶しておく。即ち、記憶部14は、「HTTP://」や「HTTP://www」、放送事業者毎の「○○TV.jp」や「○○TV.jp/bangumi/」などを要素情報として記憶しておく。そして、鍵未取得番組がフォーカスされて「選択」キーが押下されると、アドレス生成部16は、要素情報(HTTP://等)と記憶部14に記憶される当該放送番組に対応する電子配列情報のうちの一部(即ち、NID等)とを組み合わせることにより、鍵の取得先ページのアドレスを生成する。例えば、要素情報と、電子配列情報のうちのNIDおよびEIDとを組み合わせてアドレスを生成する場合、要素情報が「HTTP://」、鍵を取得しようとしている放送番組の放送事業者(NIDより特定可能)に対応して予め記憶されたNIDに対応する要素情報が「○○TV.jp」、EIDが「0525」であれば、「HTTP://○○TV.jp/0525」というアドレスが生成される。
