DVDs will soon be tracked with embedded radio transmitter chips to prevent copying and piracy, according to the company which makes movie discs for Warner, Disney, Fox and other major studios. 

The technology, which can also be used for Blu-Ray and HD-DVD discs, will allow movie studios to remotely track individual discs as they travel from factories to retail shelves to consumers' homes.

Home DVD players will eventually be able to check on the chip embedded in a disc, and refuse to play discs which are copied or played in the 'wrong' geographical region, the companies behind the technology expect.

"This technology holds the potential to protect the intellectual property of music companies, film studios, gaming and software developers worldwide," said Gordon Yeh, chief executive of Ritek Corporation. 

Ritek is the world's largest DVD maker, and its U-Tech subsidiary will make the discs. 

U-Tech and IPICO, the company behind the RFID chips used in the discs, announced today that production of the 'chipped' DVDs will begin at U-Tech's main plant in Taiwan.

U-Tech's global network of factories stamps out some 500 million pre-recorded DVDs and CDs a month for major movie studios, recording studios and video games companies.
