In the late 1990s, commercial HDTV sets started to enter a larger market, but there was no inexpensive way to record or play back HD content. JVC's D-VHS and Sony's HDCAM formats could store that amount of data, but were neither popular nor well-known. It was known that using lasers with shorter wavelengths would yield optical storage with higher d...
Toshiba-branded HD DVD players use open source software such as Linux as the GPLappears in the manuals.
If a publisher wishes to restrict use of its HD DVD content, it may use the Advanced Access Content System (AACS) although this is not required for normal disc playback. AACS is a standard for content distribution and digital rights management. It is developed by AACS Licensing Administrator, LLC (AACS LA), a consortium that includes Disney, Intel,...

Microsoft's implementation of Advanced Content is the HDi Interactive Format, and "HDi" is frequently used to refer to the Advanced Content system. Advanced Content is based on web technologies such as HTML, XML, CSS, SMIL, and ECMAScript (JavaScript), so authoring ...
Compatibility
Backward compatibilityis available with all HD DVD players, allowing users to have a single player to play all types of HD DVD, DVD and CD. There is also a hybrid HD DVD format which contains both DVD and HD DVD versions of the same movie on a single disc, providing a smooth transition for the studios in terms of publishing movies, and allowing consumers with only DVD players to still use the discs. DVD replication companies can continue using their current production equipment with only mino...
Dual-compatibility drives
In 2007, LG and Samsung released standalone consumer players that could read both HD DVD and Blu-ray Discs.[a]The machines were sold at premium prices, but failed to sell in large quantities. In May 2008, both companies announced they would stop manufacturing dual-compatibility drives. A few computer manufacturers (such as HP and Acer) sold computers with combination HD DVD/Blu-ray Disc drives. LG marketed a Blu-ray writer that also read HD DVD discs (but could not write to them).
HD DVD competed primarily with Blu-ray Disc. Both formats were designed as successors to DVD, capable of higher quality video and audio playback, and of greater capacity when used to store video, audio, and computer data. Blu-ray Disc and HD DVD share most of the same methods of encoding media onto discs with each other, resulting in equivalent lev...
Even after finalizing the HD DVD standard, engineers continued developing the technology. A 51 GB triple-layer spec was approved at the DVD Forums 40th Steering Committee Meeting (held on November 15, 2007).No movies had been scheduled for this disc type, and Toshiba had declined to say whether the 51 GB disc was compatible with existing drives and...
