Maybe we should no longer go to repeatedly mentioned the February 19, the Toshiba HD DVD business announcing the end of the matter, but numerous examples prove that can become a historic moment in the event of absolute can stand it. The battle for next-generation high-definition specification continues for as long as six years later, and finally in 08, 19, draw a, to some people, successful and on others, but very reluctant to do so.

With HD DVD's exit, there is no doubt that the DVD is not the successor of executives, Blu-ray Disc (BD) has been pushing the successor of Toshiba. The roots of his opponents "sent" baton, as next-generation high-definition format standards makers and multipliers, BD future development roadmap? how to plan?

Before the interview, we seem to be on Blu-ray victory, in the Chinese market next some touch are not clear; but after the end of the interview, dense fog seems to have been host of brilliant questions and answers and wonderful guests. Here we combine the contents of the interview, to in-depth analysis of BD in the format of the significance of the struggle for victory, and the future prospects for China's high-definition market.

● BD why would this war victory win critical junctures??

When asked why will win BD, and break in close critical junctures where, Chao-Kuei-chi (Matsushita Electric) that BD has always had its own advantages, which they can win the most fundamental reason to say the entire competition situation critical junctures, he considered the Warner Brothers announced future before at CES2008 only supports Blu-ray Disc. This decision directly for victory day ping completely backward BD and HD DVD upset in the deployment, CES2008 that HD DVD is compounded by the adverse effects, the end of the Toshiba HD DVD advocate companies had to helpless is announcing the end of the relevant business HD DVD.

We believe that the above reasons only BD can win more critical a point that is not all the BD can win. So what other factors directly or indirectly affect the Blu-ray Disc (BD) can win?

Reason ①: capacity and bandwidth advantages are

BD has the advantage of putting aside the original technical architecture, you can safely go boldly to adopt new technologies, including modem technology and so on can be detached from the original DVD. So BD features is that it is very large, BD currently applied to the issue of media is the ROM format, including DVD times have a DVD-ROM, DVD + R, DVD-R This is the standard ROM, the ROM is the release, also known as prefabricated CD, is in issue, the content of prefabricated in CD. BD single layer capacity 25GB or 27GB, double 46 or 54GB, HD DVD-layer capacity of double capacity 15GB 30GB, difference is noticeable.

Blu-ray, HD DVD and the main differences between traditional DVD

② reasons: BD has more from content ones ' support

In fact, Warner Brothers in the October speech, more performance out of the current dual-format competition the negative effects of unsatisfactory. This negative effect is to let consumers when from SD DVD

Generation of the high definition era, confused and upset. They worry about their support for the format became the second Betamax (at that time and VHS video recorder market, competition and ultimately defeat Betamax).

Blu-ray has won the support of the vast majority of the film company

Warner Brothers in order to dispel the concerns of the users, it must be in BD and HD DVD choose one. In BD and HD DVD, BD more between the upper hand, so according to Warner Brothers announced exclusive support before CES2008 BD. This download supports BD significantly ahead on HD DVD, gaoqingzhi war situation further clarified.

Reason ③ in property protection on BD do a better place, while VISTA operating system is one of the reasons

In terms of copyright protection, HD DVD only has taken the form, and AACS BD on the basis of the AACS and additional joined the BD + and ROM Mark two copyright protection technology, BD also won more software vendors ally support. 20th Century Fox is very concerned about copyright protection, so he starts more inclined to support blu-ray Disc.

Microsoft at the end of the era DVD when it joined the DVD Forum as a member of the Board, which is based on Sony competition considerations, so Microsoft supports HD DVD. Of course Microsoft proposal BD is not very friendly, which is Microsoft supports HD DVD. But Microsoft support HD DVD then become very strong, hampered portion of technology and the fusion of HD DVD, which is exactly what Hollywood studios are needed. For example, at Microsoft leading the development of copyright protection technology AACS, Fox thought less insurance, would like to join the SPDC technology, Microsoft believes that this technology will impact on the VISTA operating system release, because VISTA announced that provide a safe media path, if the HD DVD join the SPDC technology, Microsoft would have to rewrite the Vista operating system code. Early in 2005, it was reported that Toshiba may have to surrender because it alone.

Both the DVD or Blu-ray age in the era of the two factions fight, always design more advanced advanced, optical, larger, copyright protection function better and the ally more then one final win.

HD DVD is slowly from the historical stage, while those who have purchased an HD DVD users now what?
