Audio
Continuing the discussion on DRM I would like to do now some considerations on the file formats and what can be "actually bought" and how the Internet and a PC.
First you need to keep in mind that not everything can be "really" bought with the Internet, at least not with the rapid and efficient formula for the download. When the MP3 format began to become popular, it went from 20Mbyte of a song, excerpt from an audio CD, compressed file to 2M, a time-saving download 10 times lower (with variations depending on the length of the song original and the type used MP3 compression). At the time, then, was the standard dial-up modem or 56K, so the MP3 format was a real revolution that has produced all that we see today in music on the Internet radio streaming, iTunes , P2P Applications, ability to listen to hundreds of songs in our car and mobile phone, etc. ...
MP3s downloaded to a PC, these can again be converted to audio CDs and burn, so be played just like an original audio CD and without obligation to the particular devices that can read MP3 compressed format (even though today all latest devices and not only recognize MP3, DivX, AVI, JPG, etc ...). At the same time the network has been able to even find all the kit to play an original disc coopertine so who had time and inclination, could "rebuild" at home a remarkable facsimile of an audio CD, similar to that found in any store. The evolution and the low cost of inkjet printers (as is happening with photography-digital) of blank CDs and cases, have resulted in an increase of Piracy Audio esponensiale is that the "do-it-yourself production" of CD! You can even recreate the print on the blank CD superfiecie, making the final product substantially identical to the one purchased in the store (or purchased by mail)!
In practice, in short, with minimal expense to recreate the complete package of an audio CD at home, without discotics too original. We understand how all this has had and still has a considerable impact on the entire recording industry worldwide. Hence the protective systems become a central element, probably lagging the phenomenon itself.
Software Applications
I purchase and download the procedure has its maximum expression with the software applications. When you purchase software, of course, what matters most is just the "file" box and kit, in this case, are completely irrelevant. In the DRM software applications are conducive atmosphere as the only device that can work is the Personal Computer. At the time of purchase, in addition, the end user indicates the type of personal computer and operating system that has, so "verticalization" all security procedures: how the activation keys, often working only for that special "edition "application.
In the near future, however, the inclusion of operating systems in mobile devices (see the Apple iPhone) could impact on the procedures for software protection. It is clear that, in short, you can use, for example, Adobe Photoshop on our phone (or something similar, given the evolution of next generation mobile phone)! In this thing we will be forced to purchase separate licenses for use on personal computers and various mobile devices (and not) in our possession?
The breath of fresh air brought by Web 2.0 has given way to a series of "beta" designed to "move" the software, as we know, directly on the network. Adobe, for example, has announced a version of Photoshop can be accessed via your Internet browser. Different devices accessing the network will have the opportunity to use the same software. And the licenses? How is this managed?
Film video
For video, or a movie praticolare, the speech is very different! First of all, you have not found a compression format that it can be really compared to MP3. Although significant progress has been made, the video, at least to a certain quality (comparable to the famous VHS), is "heavy" and difficult to treat, both in terms of memory usage both in terms of computing time. A piece of music lasts a couple of minutes, the second less than the second, a film, by contrast, reaches an average of 90 minutes! In the end it was the reason for the development and dissemination of the elder brother of the CD: the DVD. The CD was designed for music, so basically 700Mb were sufficient, but with the video we wanted something bigger and the DVD was the answer!
When we have to do with the video the only task of scanning (conversion from raw format to a compressed video format such as AVI or MP4) computation time required machines and out of the reach of most people. Download a movie from the Internet to be able to burn still requires discrete time, which often discourage the most from even trying.
In the movies in DVD format, then digital has opened up new forms of presentation and content. In a DVD, in fact, is not normally present only the film but are placed in support subtitles in various languages (which occupy space), audio tracks in different languages (which take up space ..), special inserts, additional content, final altertnativi , custom framing, cards of the characters, usable sections of a normal PC! So a great amount of data that, if they should be downloaded from the Internet quickly, require a banda "dream"! However with time, when the connection speed will increase and the computers will be faster, but these obstacles are overcome and the ability to "buy" a movie from the network may become feasible. Do not forget, however, that the era of high definition is practically begun. A high-definition movie evidently contains much more information than those available today. We witness, therefore, to a spiral between the increase in the size of the video and the Internet bandwidth available.
The metamorphosis of the CD into DVD, which has initiated the era of digital video, is to be found today in the transition from DVD to Blu-Ray (Sony) or HD-DVD (Toshiba), technological advances required by the amount of data that high definition brings with it!
Most likely, therefore, in the short term, the convergence of the Internet / DVD will be difficult, at best restricted to a few privileged users, as already happens with Sky (which offers its high definition) in respect of DTT, without the traditional resolutions.
The first steps, then, moved by the latest Microsoft Xbox 360 and Sony Playstation 3, indicate that HD is ready to spread like wildfire, helped by information already disseminated in PC monitors 19-inch resolution 1280 × 1024 a little 'everywhere!
Publishing
The publishing industry, on the other hand, has certainly suffered less damage than everyone. Replicate a book, in fact, it is not convenient. A book lives because of its shape, the quality of its paper, the size of layout, for the peculiarity of the press, all features difficult to replicate in today's home environment. Recreating a book, after downloading from the Internet, is far from simple. Also "digitize" a book is not so easy, unless someone invents a "3D scanner" able to "copy" a text without opening it! Despite these characteristics peculiar happen to find some "chunk" of text on the net! But the damage is minimal, even on the Internet, because it is still very uncomfortable, at least for certain content: essays, novels, comics and more.
Experience of publishing in the end we see some indication of the possible solution to the problem of DRM in audio, video and software in general. Protecting a file compartment has long been a result. There is always someone ready to undermine the sophisticated safeguards are used. It is obvious that if you can not protect a file from the copy, then worth prevent the use, forget it and concentrate instead on the "why" you buy an original product. Entice the end user to purchase a legal copy of a CD, a DVD or software, can be done by offering those features that can not be replicated by a "pirate copy"!
For software, for example, assistance, access to restricted areas on the network, gadgets, special promotions on other products, free invitations to events and presentations are some of the "technical" or activities that can lead to ' purchase of an "original" an end-user.
So I think that the solution of the problem may lie in the same end user. This must be willing to buy a product, make sure you get the "service" at the end, could not possibly get because they do not "replicable."
