Information signal recording |
摘要 |
<p>A reproducing apparatus (1) such as a CD player provides to a recorder/player (2) via a high-speed bus (3) content-related information such as a digital audio signal, a content ID being identification information on the digital audio signal and a standard playing time of the digital audio signal. The recorder/player (2) has a controller (20) which stores the content ID into a copy-history information management memory (32) when the same content ID is not existent in the memory. The content ID is held for a period measured by a timer (33). For this period, the recording function of the recorder/player (2) is limited so that the same digital audio signal cannot be copied at a high speed. <IMAGE></p> |
