Reuters reports that Toshiba is delaying the launch in Japan of HD-DVD - the high-def DVD system that was due to arrive ahead of its rival Blu-ray.

According to the Reuters report,

Japan's Toshiba Corp. said on Tuesday it will delay the year-end Japan launch of its next-generation HD DVD players to address copy protection issues, potentially undermining its advantage as the first supplier to put such machines on the market.

The Japanese company had said in September the domestic launch might be postponed until after December. A spokesman for Toshiba said it would continue to push for a U.S. launch in the first quarter of 2006, most likely some time between February and March.

Toshiba said in a statement it would not launch the products until the last details on copy protection management systems, called AACS, or advanced access content system, were finalized.
