Network device and method for providing content compatibility between network devices having different respective digital rights management methods

摘要

The present invention relates to a network device and a method for providing content compatibility between network devices having different respective digital rights management methods. The method includes exchanging security program lists of the network devices, comparing the security program list of one network device with the security program list of the other network device based on the exchanged security program lists, and installing a security program required for using content of the other network device according to the comparison result. Accordingly, there is an advantage in that the network devices using the different respective DRM-based security programs can exchange content with one another and use the content of the other network device by using the predetermined security program update methods.
