| Licensing Starts for Copy Protection Technology for IEEE1394
|
|
September 29, 1998 (TOKYO) -- Four Japanese companies and Intel Corp.
on Sept. 23 started licensing copy protection technology to prevent
content transmitted via the IEEE1394 standard interface from being copied
illegally.
|
The Japanese companies are Sony Corp., Toshiba Corp., Hitachi Ltd. and
Matsushita Electric Industrial Co., Ltd.
The companies enable the IEEE1394 interface to be used to transmit digital
content such as movies by adopting preventive measures against content
copying. In June 1998, the five vendors, including Sony, established
the U.S.-based Digital
Transmission Licensing Administrator, to license copy protection
technology. DTLA is responsible for the licensing administration business.
IEEE1394-based copy protection technologies have been evaluated by the
Copy Protection Technical Working Group (CPTWG), an industry group organized
by devices makers, movie companies and other businesses. The CPTWG has
narrowed down the specifications to the most promising three proposals.
The copy protection technology inaugurated by the five vendors is one
of the three proposals under consideration by the CPTWG. The CPTWG is
unlikely to decide on the final specifications until after the five
vendors have started the technical licensing service. For this reason,
device manufacturers must undertake product development in the light
of the three proposals.
