Toshiba has delayed the introduction of its first HD DVD players in consequence of problems concerning Advanced Access Content System (AACS) licensing. The company is said to have completed the design of products for the US and Japanese markets and will start volume production as soon as the AACS matter is solved. Toshiba is the main supporter behind HD DVD. Rival companies backing Blu-ray are expected to present the finalized BD-ROM format at CES in Las Vegas.
