METHOD FOR AUTHORIZING CONTENTS PLAY RIGHT IN USE OF RECORDING MEDIUM

摘要

A method for assigning a content playback right to an offline video device through a recording medium is provided to enable the offline video device to play the contents stored in the recording medium and requesting the playback right for playback by assigning the playback right to the offline video device through the recording medium. An encoded key is recorded to the recording medium. The contents encoded by the key are recorded to the recording medium. Information for the playback right to play the contents recorded in the recording medium is recorded to the recording medium(S360). The playback right includes the information for the video device receiving the playback right. The video device determines whether the playback right is permitted or not by referring to the permitted video device information included in the playback right recorded in the recording medium. If the video device corresponds to the permitted video device, the video device decodes and plays the encoded contents recorded in the recording medium.
