Multimedia Streaming Technology in Broadband Networks 3 - Digital Rights Management System
Hideki Yamamoto · 2002
With the spread of broadband, services for distributing digital contents, such as software, games, video, and the like, (or “content distribution services”), have started to take off in a real way. However, the fact that digitalized contents can be copied very easily has prevented content rights holders from adopting a more positive attitude to content distribution. For content holders, the key functions required in a content delivery system are unified management of copyright information supplied to the distributor, control of delivery servers on the basis of this copyright information, and encoding of the information streams. This essay looks at these different functions, which are all installed in the OKI MediaServer.
