| | | | Copy protection - Case study: Steam: Encyclopedia II - Copy protection - Technical challenges From a technical standpoint, it would seem theoretically impossible to completely prevent users from making copies of the media they purchase, as long as a "writer" is available that can write to blank media. The basic technical fact is that all types of media require a "player"—a CD player, DVD player, videotape player, computer, or video game console, to give five examples. The player has to be able to read the media in order to display it to a human. In turn, then, logically, a player could be built that first reads the media, and then writes out an exact copy of what was read, to the same type of media, or perh ...

| | | | Copy protection - Case study: Steam: Encyclopedia II - Copy protection - Copy protection on older media Copy protection has been attempted in many ways, long before computers and digital media entered the picture. For example, the ancient practice of watermarking is an attempt to at least prove the authenticity of the original, though this does not itself prevent copying.
The music industry in particular has long sought a reliable copy protection method—early attempts included adding a high frequency spoiler signal to an analog recording so that tape recorders would generate an unpleasant whistle when the spoiler heterodyned wi ...

| | | | Copy protection - Case study: Steam: Encyclopedia II - Copy protection - Copy protection for videotape Companies like Macrovision provide schemes to videotape publishers making copies unusable if they were created with a normal VCR. All major videotape manufacturers license Macrovision or similar technologies to copy protect their videotapes.
Starting in 1985 with the video release of "The Cotton Club", Macrovision has licensed to publishers a technology that exploits the automatic gain control feature of VCRs by adding pulses to the vertical blanking sync signal. These pulses do not affect the image a consumer sees on his TV, but do c ...

| | | | Copy protection - Case study: Steam: Encyclopedia II - Copy protection - Copy protection in recent digital media More recently, publishers of music and movies in digital form have turned to encryption to make copying more difficult. CSS, which is used on DVDs, is a famous example of this. It is a form of copy protection that uses 40-bit encryption. Copies will not be playable since they will be missing the key, which is not writable on DVD-R or DVD-RW discs. With this technique, the work is encrypted using a key only included in the firmware of "authorized" players, which allow only "legitimate" uses of the work (usually restricted forms of playback, b ...

| | | | Copy protection - Case study: Steam: Encyclopedia II - Copy protection - Copy protection for audio CDs Starting in 2000, music publishers started to sell some CDs with various copy protection schemes. Most of these are playback restrictions that aim to make the CD unusable in devices that can also be conveniently used for duplicating (e.g., CD-ROM drives in computers), leaving only dedicated audio CD players for playback. This does not, however, prevent such a CD from being copied via analogue connections, ...

| | | | Copy protection - Case study: Steam: Encyclopedia II - Copy protection - Business rationale Copy protection is most commonly found on videotapes, DVDs, computer software discs, video game discs and cartridges, and more recently, some audio CDs. Historically, most companies that publish works on these media have believed that copy protection will increase the company's revenues, by limiting the ability of the consumer to make copies of the media. In the absence of copy protection, most of these media are relatively easy to copy in their entirety using a machine (as opposed to photocopying each page of a book). This results in a situ ...
