digital TV broadcasting. The encoding of the stereo subcarrier also differs between NTSC-M/MTS and Japanese EIAJ MTS broadcasts. Marketing definition The term NTSC-J is also incorrectly and informally used to distinguish regions in console video games, which use televisions. NTSC-J is used as the name of the video gaming region of Japan (hence the "J"), South East Asia (some countries only), Taiwan, Hong Kong, Macau, Philippines and South Korea (now NTSC-K) (formerly part of SE Asia with Hong Kong, Taiwan, Japan, etc.). Most games designated as part of this region will not run on hardware designated as part of the NTSC-US, PAL (or PAL-E, "E" stands for Europe) or NTSC-C (for China) mostly due to the regional differences of the PAL (SECAM was also used in the early 1990s) and NTSC standards. Many older video game systems do not allow games from different regions to be played; however more modern consoles either leave protection to the discretion of publishers, such as Microsoft's Xbox 360, or discontinue its use entirely, like Sony's PlayStation 3. China received its own designation due to fears of an influx of illegal copies flooding out of China, which is notorious for its rampant copyright infringements. There is also concern of copyright protection through regional lockout built into the video game systems and games themselves, as the same product can be edited by different publishers from one continent to another.
