DVD region locking isn't much of a "technical control". There are 8 regions, because that's the number of bits in a byte. The region lock is a single byte that specifies which regions are intended to read the disc. On the honor system, a DVD player is supposed to read this byte, check the bit for its region, and refuse to play the disc if the bit is unset. The only "control" here is that it's assumed you don't have a copy of the DVD spec and don't realize what the lock consists of. Ignoring it suffices to bypass it. |
