Title:
自由放送と平行して暗号化されたコンテンツ
Document Type and Number:
Japanese Patent JP2007525122
Kind Code:
A
Abstract:
The present invention relates to a method and a device ( 103 ) for acquiring content from an information transmission ( 101 ). The invention is based on the idea that an information transmission is received via a transmission channel. Along with the information transmission, which e.g. is a broadcast from a radio show, an encrypted, digitally storable version of the broadcast is transmitted and received ( 102 ) by a listener. On the receiver, the listener can effect a download operation of a song that is currently played by means of e.g. pressing a dedicated key on the receiver front end, the receiver extracts the encrypted, digitally storable copy of the song from the information broadcast and downloads it to a storage capacity in connection to the receiver. The listener can thereafter choose to replay the downloaded song by effecting a replay operation. The receiver will thus decrypt the encrypted content and render the downloaded content.
