According to a report in the ITmedia Blu-ray DVD and HD DVD the common use of next-generation high-definition disc copy protection-encryption technology "AACS" has recently finalized, and begin to foreigners, which license to hardware product listing to remove the last barriers.
"AACS (Advanced Access Content System)" by IBM, Intel, Microsoft, Panasonic, Sony, Toshiba, Disney and Warner, information, electrical appliances and Hollywood film makers from the joint development of copyright protection, encryption, and access to competing Blu-ray and HD DVD two next-generation high-definition DVD standard.
AACS originally scheduled for October this year yet, November issue an authorization code, but substantial delays related to the progress and result in HD DVD product launch time of delay. This is the official outgoing messages, or verdict confirmed on high-definition video analog output restrictions and regional codes and suspended for outstanding projects, making Blu-ray and HD DVD two standard specification to determine the actual mass production, entered the market phase.
Japan region in 2010 will not high-definition video analog output function restrictions.
The widespread use of chromatic aberration Terminal, as is the use of the analog transmission of images, could not effectively protect the transmission of images is not bootlegging, therefore participating in the Warner Brothers AACS company proposal to join the ICT (Image Constrain Token, resist tags) is set to allow the movie to the HD movie of analog output restrictions, when ICT starts, simulation method of image transfer will be limited to the following standard resolution 480p, 720p, 1080i high-definition video, is only allowed to have encrypted protection of digital output terminals (such as HDMI) for transmission.
But because of current high-definition TV products still have a lot of chromatic aberration only with analog terminals (or variants of D-Terminal) input, Japan market particularly, if ICT must be enforced so that means that the user will not be able to watch high-definition disc program, so the limitations were Sony ICT and most electrical appliances, Panasonic, etc.
In this draft as published by the AACS content, then the term is used as the buffer way, in 2010, before 31 December, for Japan, and so is not in high-definition digital broadcasting in the area of ICT limit the Blu-ray or HD DVD movies, will force the cancellation of ICT, the full liberalization of the high-definition movie of analog output function.
2011 after 1 January of the movie by publishing self decided whether restrictions on ICT, 2014 next player hardware you need to fully abolish the analog video output interface, including Composite (AV), S, chromatic aberration, the terminal must be repealed and completely replaced-HDMI with encrypted protection of digital interfaces. This measure is substantially lifted Japan region of high-definition video analog output restrictions, existing analog interface high-definition TV users, at least in all by the year 2010 does not have to worry about ICT restrictions. However the main articles are for the rest of Japan, the status is not clear.
Japan manufacturers in this standard-setting won special case, Japan's law was no small role. According to the Japan ARIB (ARIB) developed by the application of digital broadcasting, there is the prohibition of the use of ICT terms require setting ICT = 1 (allowed analog output).
On the other hand, ICT end use, also by the content provider. Hardware though mandatory support, but software in production if not to join the ICT function, which means that the player can output HD signal analogue interface. Currently, support for Blu-ray DVD's three major film companies-Disney, 20th Century Fox and Sony Pictures will make clear that you will not use the ICT function. One of the Walt Disney Company's technical staff thinks: "join the ICT function of CD-ROM is likely to be resisted by user, or return requirements for ICT will probably not be the final application, I am optimistic. ”
Substantial simplification of the Blu-ray movie partition mechanism
About the movie part of the partition, in accordance with the relevant reports, because most of the large Hollywood global synchronization works, the demand for a partition, the weaker the partition will Blu-ray greatly simplified into three major regions, half of the existing DVD, Division for America, East Asia (Japan, Korea, Taiwan, Southeast Asia and so on) is 1 area, Europe, Africa, sector 2, China and Russia for the first 3 districts.
As part of the HD DVD, previously led manufacturers Toshiba has indicated that consider repealing partition mechanism, but the programme is adopted, there has not yet been determined.
