CONTENT MANAGEMENT PROGRAM, METHOD AND DEVICE
First Claim
1. A content management program, allowing a computer to execute:
- an access information setting step of setting the access information that controls whether or not the reproduction of the content should be made for each content stored in the content storage unit;
a content reproducing step of reproducing said content when said access information is shown as reproducible and prohibiting the reproduction of said content when said access information is shown as not reproducible;
a content transfer step of converting a resolution of the content stored in said content storage unit and transferring the content after the conversion to another device; and
an access information control step of setting said access information to be reproducible when the content is stored in said content storage unit, and setting said accessing information to be not reproducible, thereby prohibiting the reproduction when the content after said conversion is transferred to another device, and moreover, setting said access information to be reproducible, thereby making it reproducible when the content after the conversion and transferred to said another device becomes not reproducible.

Abstract
An encrypted content and its encryption key under a copy right use condition of prohibiting a copy by the device having received a content are stored, and the encrypted content is copy-transferred with another device through the network, and at the same time, the encryption key is transferred through the network, so that it is stored in either one of the devices.
Even when a high definition television broadcast signal received with a copy-once taken as a copy right use condition is recorded, an access flag that controls the presence or absence of the reproduction of the broadcast content for each broadcast content is provided. When an original broadcast content is transcoded into a low resolution, and is transfer to another device, its access flag is turned on, thereby making the reproduction possible.

10. A content management program, characterized by allowing a computer to execute:
-
a content storing step of storing a plurality of CODEC steps reproducing the same content in parallel by receiving signals and a plurality of same contents reproduced in parallel by the plurality of CODEC steps in a content storage unit; a flag control step of turning on any one of the access information set for each same content stored in said content storage unit and setting the corresponding content to be reproducible, and at the same time, turning off all the remaining access information and prohibiting the reproduction of the corresponding content; and a content reproduction step of selecting said content with the access information turned on from among the plurality of same contents and reproducing the same. - View Dependent Claims (11)

12. A content management method, characterized by comprising:
-
an access information setting step of setting access information that controls whether or not the reproduction of the content should be reproduced for each content stored in a content storage unit; a content reproducing step of reproducing the content when said accessing information is shown as reproducible, and prohibiting the reproduction of the content when said access information is shown as not reproducible; a content transfer step of converting resolution of the content stored in said content storage unit and transferring the content after conversion to another device; and an access information control step of setting said access information to be reproducible when the content is stored in said content storage unit, and setting said access information to be not reproducible, thereby prohibiting the reproduction when said content after conversion is transferred to another device, and moreover, setting said access information to be reproducible, thereby making the reproduction possible when the content transferred to another device and converted thereafter is not reproducible. - View Dependent Claims (13, 14)
