AACS (AdvancedAccessContentSystem) by IBM, Intel, Microsoft, Panasonic, SONY, Toshiba, Disney and Warner, information, electrical appliances and Hollywood film makers from the joint development of copyright protection technology, and access to competing BD and HDDVD two-order analysis of Blu-ray laser laser video standards.
AACS originally scheduled for October this year yet, November issue an authorization code, but substantial delays related to progress and cause product launch time by HDDVD. This is the official outgoing messages, or verdict confirmed on high resolution images of the analog output restrictions and regional codes and suspended for outstanding projects, making BD and HDDVD two standard specification to be bottom up, enter the actual production market phase.
Japan region in 2010 will not high resolution imaging of the 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, participation in the formulation of Warner had AACS proposals into ICT (ImageConstrainToken) setting for the movie business to high resolution film simulation output restrictions, when ICT starts, simulation method of image transfer will be limited to the following standard resolution 480p, 720p, 1080i, high-resolution image is only allowed to have encrypted protection of digital output terminals (such as HDMI) for transmission.
Because of current high resolution TV products still have a lot of chromatic aberration only with analog terminals (or variants of D-Terminal) input, Japan market particularly, the restrictions were most ICT appliances ' objections. In this draft as published by the AACS content, then the term is used as the buffer way, in 2010, for Japan, and so there are no high resolution digital broadcasting in the region to adopt ICT restrictions introduced by the BD or HDDVD movie that will force the cancellation of ICT, the full liberalization of high-resolution film simulation output function.
2011 after the launch of the film 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abolish the analog video output interface, including Composite (AV), S, chromatic aberration, the terminal must be repealed and completely replaced-HDMI with encrypted protection of digital interfaces.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 resolution images of the analog output restrictions, existing analog interface high-resolution 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.
Blu-ray DVD protection technology decision
About the movie part of the partition, in accordance with the relevant reports, since the current Hollywood works full of global synchronization, the demand for partitions, so the weaker BD movie partition will significantly simplify the 3 large 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.
The information, the United States, Taiwan and Japan is divided into the same area, so the next three to the BD player and movie will mutually negotiable, unlike existing DVD that are affiliated with in three different regions, are not interoperable. As part of the HDDVD previously dominant manufacturer Toshiba has indicated that consider repealing partition mechanism, but the programme is adopted, there has not yet been determined.
