DVD REGION CODING
Region Playback Control Management
All DVD Video Playback systems have “Region Playback Control” (RPC) which is
required by Hollywood movie industry and defined by DVD Forum. 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 code of such drives can be
changed up to 5 times by end users under some software decoder. (e.g. PowerDVD)
