DRM - is Digital Right Management, which translates as "digital rights management".Thus, the answer to the question: "DRM-defense - that it" - would be: "This is a class of technologies that are used by publishers to control the content."This can be expressed in this way: the audiobook, which was acquired in digital form on the website will normally be played back on the computer with the help of the acquisition was made.But if you copy it to another computer, it becomes unnecessary files that can not be opened by any player.
These examples on the use of DRM technologies may be much more difficult.
DRM from the outset was developed to prevent copying of digital products.But the next generation of technology enabled tools to restrict viewing, printing, editing.
When you try to protect the interests of copyright holders DRM-protected caused a considerable number of complaints from users who purchase digital products.The inability to use purchased music via different devices, negative impact on consumer demand.As a result, publishers have realized that there is the possibility of selling music digitally without overlapping protection DRM.This will be even more successful.In other words, DRM-protection even negatively affected the sales of various digital products.
DRM-protection - what is it?
These technologies over time were able to enlist the support of the law.For example, in a large number of countries have rules in the laws that prohibit circumvention of copy protection.In these states, arguments about whether there should be DRM-protected, how to remove it, and so on, have in fact illegal.
But DRM is also associated Another difficulty due to the fact that such technology may become an obstacle for users in the realization of their legitimate rights.That is why, in order to understand, DRM-protection - that is, you must realize that it is not available backups purchased product.
Without going into legal practice in the application of different laws in everyday life have the opportunity to propose a scheme, how to remove DRM-protection that is completely legal in most states.An exception will only except Australia.You can create multiple copies for their own use or for the provision, but not for sale or distribution.It should be noted that the process of making copies of more than 10 pieces can be regarded as commercial use.Therefore it is necessary to avoid copying more than the norm.No clear restrictions on the creation of copies.For this reason, DRM technically possible loss somewhere in the process of obtaining copies of mp3, which are not protected.But the use of the program, which is designed to disable the copy protection, may be a violation in terms of the laws.Thus, talking about how to get around DRM-protected, it must be remembered that this should be done for their own purposes.
how to implement it?
But it is good that this technology is possible to remove and use the software for general use, which are not covered DRM-protected.How to remove it?The best example in this case is the application mp3Recorder Studio.To do this, you need to enable playback of the audio file with the acquired protection required for using this program (WMP, iTunes or another).Next you need to capture the sound using mp3Recorder Studio, and then save the audio directly to mp3.In this process will be used by the built-in sound card, which allows you to capture audio in the middle of the instrument.Most sound cards provided a recording device, which is called "Stereo Mix".However, using different names.This device allows you to capture everything that plays a sound card.To do this, you may need to install the latest driver from the official website of the card manufacturer.Typically, the driver that automatically installs of Windows, often cut off and hide such a device.
«digital rights management" (or, more simply, the system of copy protection) within the meaning of copyright law should protect.But in reality it is enough that does not fulfill its main function, but also makes the PC accessible to burglars.How and why is this happening?
What to decrypt DRM?
DRM systems may be unsafe.If the wrong option for the implementation of copy protection possible opening holes in the security of your computer, which, in turn, in the absence of DRM would remain closed.Here, the fact that blocking normal copying functions in OS software packages RMS require the broadest access rights to system files and hook into the management of such functions.
good example of an unsafe implementation of this technology will serve as a protection system against copying audio CDs from the company Sony BMG.This rootkit has been placed on a large number of audio CDs from the music label, which is one of the most famous in the world.When such a disc is loaded into the CD-ROM drive, automatically starts the installation program for XCP WINDOWS.She was supposed to protect against copying an entire album or theft of the tracks from the disc.
XCP rootkit to penetrate deep into the operating system, while it is installed completely independently.The ability to uninstall using conventional methods was not possible.Also during the operation, he was a big part of the memory and could be the cause of failure.But most importantly - about the rootkit and about its functioning absolutely nothing has been written in the user agreement (EULA).This is all despite the fact that such an agreement almost no one reads.
But overriding is that the XCP rootkit created a real threat to the entire system.For example, after installing all the files that begin with the $ sys $, acquiring mode "hidden".It was once used by virus writers.For example, a Trojan Breplibot, which are sent as attachments to the E-mail'am, and found only antivirus programs.The users like unsafe files were completely invisible.
DRM-protection to WMV and WMA files is done in stages.
These days most downloaded audio and video files that are protected (WMP, iTunes, Rhapsody, Napster, Bearshare, Spiral Frog), are DRM-files.
file recording process is not complicated.There is a free method to remove DRM protection from WMV files and WMA.This is done in two passes.
1. It is necessary to write the file DRM WMA to CD or DRM WMV to disc DVD.
2. It is necessary to remove WMV and protected WMA on the PC itself, then DRM-protected will be disabled.
method of rewriting
This method is the most popular and affordable.He is writing down DRM WMA and DRM WMV files with a conventional converter, which converts the recorded and unprotected files.It is because of the fact that this technology is an easy-to-use formats that are different from the DRM WMA and DRM WMV, will also be supported by converters type SoundTaxi, NoteBurner and others.But there are some downsides.
Hook Hook - is an advanced technology, with which can be disabled EPUB DRM-protection.When comparing these programs with this type of rewrite is significantly faster conversion.When this force is difficult to work with some of the DRM formats, which have new encryption technique quality.
After a test result was obtained that the protection of DRM WMA and DRM WMV simply removed using Digital Music Converter.The program can extract audio content from files DRM WMV.Also, the program supports other unprotected formats such as: mp3, M4b, M4A, WAV, AC3, AAC.
Steps for converting:
1. To begin to add DRM WMA, DRM WMV or other files that are not protected.
2. It is necessary to select the outgoing format.
3. Next, click on the "Start" ("Start") and enter the license number.
What is DRM?What you need to remove DRM from WMA WMV files?
Speaking about the significance of the term "DRM-protection" (what is this - we generally considered above), you need to know: are programs that protect against copying and difficult actions that are related to video and audio files.For example, if downloaded from WMP WMA or WMV protected by DRM, then they can reproduce only by means of compatible devices.If every song was with DRM, the user would have to buy the track on the disc to listen to it with the music player or radio.For example, if you have purchased music on iTunes, and they listened to iPOd, is due to the fact that they have already been purchased, the user will not need to perform this action again and again.You just have to remove the file from DRM, and it will be able to play on iPod, Zune, PSP, CD-player, PCs and other devices.
This method is not entirely suitable, and sometimes it can even cause damage to CD-Roma.WMP has the ability to record files only DRM WMA and DRM WMV.For other formats require DVD-Ripper.
Due to the long recording process, the conversion speed is not better.When the recording process may lose much of the quality of the video or audio.
