A TS Bitstream Parsing System for ChinaDRM
Yueyang Zhou, Weiguo Lin, Huiqin Wang, Pengfei Jiang · 2019
Due to the increasing demand for domestic digital audio and video services, broadcast TV intelligent terminals are rapidly iterating, and global content producers are turning to researching 4K HDR technology. China needs to realize the importance of digital rights, which is more conducive to the development of ultra-high-definition digital services in China. Therefore, this paper will introduce the architecture of China digital rights management (ChinaDRM) and its application in TS encapsulation format. In the meantime, we proposed an analytical method about the TS bitstream which had been encrypted. In the TS bitstream, it also carried the ChinaDRM descriptor and Content Encryption Information (CEI). Finally, we designed a bitstream parsing system to parse the data of CEI and ChinaDRM descriptor.
