Abstract

See full text

Provided is a method of sharing content to which digital rights management (DRM) is applied. In the method of sharing the content between a first device storing the content and a second device while they are connected, the first device receives a request for transmission of the content from the second device, determines whether it is connected to the second device and generates license information regarding the DRM, and transmits the license information and the content to the second device. Accordingly, content to which DRM is applied can be shared between a plurality of devices only when they are connected, thereby removing a need to redundantly purchase the DRM content and allowing the content to be conveniently shared. Also, since the content can be shared when the devices are physically connected, degradation of the quality of sound or interruptions can be minimized.
