Broadcast Protection Discussion Group
- BPDG
http://www.cptwg.org/assets/bpdg/home%20page.htm
The Broadcast Protection Discussion Group is a working group comprised
of content providers, television broadcasters, consumer electronics manufacturers,
information technology companies, interested individuals and consumer
activists. The group was formed specifically for the purpose of evaluating
the suitability of the broadcast flag for preventing unauthorized redistribution
(including unauthorized redistribution over the Internet) of unencrypted
digital terrestrial bradcast television (DTV) and to determine whether
there was substantial support for the broadcast flag. The group completed
its mission with the release of the BPDG Report http://www.cptwg.org/assets/bpdg/bpdg%20preport.doc
Broadcast Flag
The broadcast flag is a sequence of digital bits embedded in a television
program that signals that the program must be protected from unauthorized
redistribution.
Digital watermark
A pattern of bits embedded into a file used to identify the source of
illegal copies. For example, if a digital watermark is placed into a master
copy of an audio CD or a DVD movie, then all copies of that disc are uniquely
identified. If a licensee were to manufacture and distribute them in areas
outside of its authorized territory, the watermark provides a trace.
