Title:
ＤＲＭコンテンツ並列パッケージング装置及びそれを含むＤＲＭコンテンツ並列パッケージングシステム及びＤＲＭコンテンツ並列パッケージング方法
Document Type and Number:
Japanese Patent JP7245401
Kind Code:
B2
Abstract:
The present invention relates to a parallel packaging device for DRM content, a parallel packaging system which is for DRM content and comprises same, and a parallel packaging method for DRM content, which make it possible to reduce the time and amount of computation required for DRM packaging regardless of the capacity of a piece of image content. A parallel packaging device for DRM content according to an embodiment of the present invention comprises: a Network Abstraction Layer (NAL) dividing module which divides a piece of image content including a plurality of NAL units into the individual NAL units; and a parallel packaging module which uses a CABAC decoder to decode each of the plurality of NAL units divided by the NAL dividing module, packages DRM metadata into QTC data extracted through the decoding, and encodes NAL units for which the DRM metadata packaging is completed.
