China's top electronics makers unveiled dozens of video players made with a homegrown DVD format in a campaign to promote a Chinese alternative to foreign technology.

The DVD format, known as EVD, is part of state-backed efforts to create standards for mobile phones and other products and reduce dependence on foreign know-how and possibly reap licensing fees if they are adopted abroad.

EVD, or Enhanced Versatile Disc, was first released in 2003, but an effort to promote it was dropped in 2004 after the players failed to catch on with consumers and producers squabbled over licensing fees.

Now Chinese electronics makers have revived the campaign on a massive scale, saying they plan to switch completely to EVD by 2008 and stop producing DVD players. Electronics makers, film studios and retailers are promising to sell EVD discs and players.

The move also adds a new twist to rivalry between the HD DVD and Blu-ray Disc next-generation video standards being promoted by competing groups of US, Japanese and European companies.

Promoters of EVD say it provides crisper pictures and sound, bigger recording capacity and better anti-piracy features than standard DVD.

Chinese sales of high-definition TV sets next year are expected to grow by 60 percent to 8 million units, driving sales of video players, Zhang said. He said producers plan to start trying to export EVD machines next year.

Chinese companies produce 80 percent of the world's DVD players under their own brand names and for foreign electronics companies or retailers. But manufacturers complain that fees paid to foreign owners of technology cut into profits in a highly competitive industry.
