'Type Code = v
Vendor Resets = w
User Change = x
Region Mask = y
Playback Control Scheme = z'
where:
v = 0: no drive region set;
v = 1: drive region set;
v = 2: drive region set /w additional restrictions
(last chance);
v = 3: drive region has been set permanently
w = count down the number of times available for
manufacturer reset of region.
x = count down the number of times available for
user / manufacturer reset of region.
y = specifies the drive region in which the drive is
located. Each bit represents one of eight
regions. If a bit is cleared in this field, the disc
can be played in the corresponding region.
z = 0: does not enforce Region Playback Controls
z = 1: adheres to this specification and all
requirements of the CSS license agreement for RPC.
'OK'
Note: The factory sets the region code for a console
by asserting a console variant (CV) ETAP command,
which is the recommended method of changing
region code. It is possible, however, to change the
region code of a console by sending a separate
"RC x" ETAP command as shown here.
Note: Be aware that changing region code by using
"RC x" may cause the region code mismatching
between the DVD drive and the Main board software,
and may cause the unit to not work. Sending 'RC'
with no argument will query the region code.
