r> TORONTO, May 4 - Tri-Vision International Ltd./Ltee (TSX:TVL) today announced that it has licensed its V-chip technology under United States Patent No. 5,828,402 to ViewSonic Corporation of the USA. ViewSonic was already awarded a license for Tri-Vision's Canadian V-chip, Patent No. 2,179,474, in January of this year. The licenses are valid through the expiration of the patent in 2016.

Companies which have acquired V-chip licenses for Tri-Vision's Canadian Patent No.2,179,474 and/or U.S. Patent No. 5,828,402 include: Sony, Hitachi, Sanyo, Philips, JVC, Matsushita, Sharp, Pioneer, Apex Digital, Samsung, LG Electronics, Funai, Orion, Toshiba, Eastech, Erae Electronics, Seiko Epson, Shenzhen KXD, Newlane, Xiamen, Konka, Optoma, Coretronic, TTE, Syntax-Brillian, Akai, Chunghwa, NEC and many others.

As part of the transition to a digital television broadcast system in the United States, the Federal Communications Commission (FCC) has mandated new rules to ensure that the V-chip can respond to any rating system changes in all digital television receiver products. Tri-Vision's open V-chip (also known as V-chip 2.0) is the only known patented technology capable of accepting modified or new rating systems. The FCC ruling took effect on March 15, 2006.
