Decoder Data
Decoder, the encoder (ENCODER) Encryption (ENCRYPT) unlock the information before the program or hardware.
DeCSS
To learn more about DeCSS, we must first understand why CSS. In short, DeCSS to break the CSS measures to prevent loss of the process, both a code is a piece of software. DeCSS can be used to "guess" out of this group of encryption, in a computer generated 400 key to making the process ineffective. The first secret of the software program CSS solution appeared in October 1999. Those who support the DeCSS point out that it allows soft DVD player to operate in Linux, its open source nature should be excluded from CSS licensing restrictions on outside. But now very popular on the Internet to download DeCSS software DeCSS.exe, is actually a visual operating system, which is obviously intended for the copy of the film. CSS to bypass passwords and password cracking DeCSS on a DVD of the difference is that the latter is under the DMCA and the WIPO treaty in not allowed. In fact, DeCSS is not the only way to copy DVD content, such as the DVD player to copy, or from a laser CD copies, etc.. January 2000, DVD Industry Alliance CCA sued DeCSS, Connecticut and New York district court, the MPAA issued a ban on the Internet in accordance with the dissemination of DeCSS injunction, but only distribute DeCSS, including the content, not including the link. The former reason is the improper use of trade secrets, while the MPAA is a circumvention of copyright reasons. Then, a young Jon Johansen of Norway to the dissemination of DeCSS on the Internet for the first time information, and has been the local police raided the confiscation of computer equipment and mobile phone, but Johansen pointed out that people really crack the code of the two non-celebrities, namely, Germany people and the Dutch, they claim to "reverse engineer guru" (Masters of Reverse Engineering, MoRE). To the copyright point of view, CCA is certainly trying to ban the DeCSS code posted on the web, but in highly developed Internet today, almost a total ban is unlikely to matter. So far, the court will still stand on copyright or intellectual property of the party, will be posted DeCSS code to the person or group be punished.
DECT digital wireless telephone technology regulation
(Digital Enhanced Cordless Telecommunications)
Launched in Europe in 1992, low-power mobile phone standard, the advantage of a base station through a simple set up can be carried out in a small-scale regional calls, while eliminating the calculation of call rates, a farm in North America or the facility, located in an internal communication communication tool.
Currently there are opening up this standard, using frequency 1880 ~ 1900MHz, can be used without licensing, but the DECT phones to be certified by Directorate General of Telecommunications before sale. DECT base station covering a radius of 100 ~ 150M, the domestic enterprises, including Taiwan Semiconductor Manufacturing, etc. used.
DECT uses a TDMA digital transmission. Italy in 1998 launched the world's only public service.
Deep Computing
Deep Computing is the heavyweight supercomputer, with its powerful computing capability analysis large amounts of data, the level of development similar to the wisdom of the human mind, such as the pharmaceutical improvements, weather simulation, and even genetic engineering.
The term derived from the Deep Computing IBM. By definition, refers to the use of advanced mathematical models, combined with sound analysis software and powerful servers, the huge data flow to a high degree of screening, analysis and sophisticated analog computing, end up with the level of human thinking is similar to the result.
After a large number of developing such a database generated by computing the results will be developed unexpected applications, including a variety of diseases, science, life applications, solutions, or the development of ways to calculate the weather, or the scope and impact analysis of nuclear explosion , for unknown things Prediction and evaluation, will be more accurate than ever.
The most impressive depth of operations, none other than IBM has swept the world's super-computer "Deep Blue", its enough to play chess which competed with human skill, that is, a large number of complex data through a deal with the depth of operation, the resulting application example. |
