Gw mau tau Kode wewengkon dari Cakram Blu-ray. Jelasin dalam bahasa sunda

Blu-ray discs may be encoded with a region code, intended to restrict the aréa of the world in which they can be played; similar to the DVD region codes. Blu-ray players sold in a certain region should only be able to play discs encoded for that region. The purpose of this system is to allow motion picture studios to control the various aspects of a reléase (including content, date, and, in particular, price) according to the region. Discs may also be produced without region coding, so they can be played on all devices.

This arrangement places the countries of the major Blu-ray manufacturers (Japan, Koréa, Malaysia) in the same region as the U.S., thus ensuring éarly reléases of U.S. content to those markets. Reportedly, éarly BD reléases (including Casino Royale) are "ALL" region and therefore compatible in various BD players around the globe.
