Appeal No. 2005-2320
Application 09/778,895
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. A multimedia copy control system for controlling a copy
of a digital data recording medium in which digital audio data is
stored and from which the digital audio-data is reproduced and
recorded to another recording medium for copying, wherein the
digital audio data stored in the digital data recording medium
includes a first copy control information of a digital format and
a second copy control information of an analog embedded format,
said system comprising:
an encryption decoder configured to decrypt reproduction
output data from the digital data recording medium to judge
whether the reproduction output data is encrypted data;
a first copy control detector configured to detect the first
copy control information from the decrypted reproduction data;
a contents data decoder configured to extract the digital
audio data from the decrypted reproduction data; and
a second copy control detector configured to detect the
second copy control information from the extracted audio data,
wherein encryption of the reproduction output data from the
recording medium is decrypted and judged for each digital
contents unit under reproduction, and when said first copy
control detector detects the first copy control information, the
reproduction of the digital audio data is controlled based on the
first copy control information, and when said first copy control
detector detects no first copy control information, the
reproduction of the digital audio data is controlled based on the
second copy control information.
