DVD Region Coding
Region Playback Control Management
All DVD Video Playback systems have “Region Playback Control”
management (RPC) which is required by Hollywood movie industry
and defined by DVD Forum. This includes DVD-Video players and
PC systems with DVD-Video capability. You can only play DVD-
Video discs with the same region code as your DVD-Video Playback
system.
As for DVD-ROM drives, one kind of the DVD-Video Playback
system, there are 2 types:
RPC Phase 1 (as RPC1)
: RPC1 drives do not have built-in hardware
support for region management. DVD-ROM drives of this kind don’t
play a part in controlling the playback region. It solely depends on
the decoder.
RPC Phase 2 (as RPC2)
: RPC2 drives maintain the region change
count information in hardware, and in general, the region of such
drives can be changed up to 5 times by the end users under some
software decoder (e.g. PowerDVD).
And referring to the region codes, there are 6 regions worldwide, and
normally, there is a region code mark on the package of DVD titles. :
