Serial Copy Management System
The Serial Copy Management System (SCMS) is a copy protection scheme that was created in response to the digital audio tape (DAT) invention, in order to prevent DAT recorders from making second-generation or serial copies. SCMS sets a "copy" bit in all copies, which prevents anyone from making further copies of those first copies. It does not, however, limit the number of first-generation copies made from a master. SCMS was also included in consumer CD-R, MiniDisc and Digital Compact Cassette (DCC) players and recorders. With the demise of these formats, SCMS is not in widespread use. However, the concept of SCMS was resurrected in the broadcast flag, a measure formerly mandated by the Federal Communications Commission (FCC) to limit the copying of digital TV signals. SCMS flags are also included in the MP3 specifications, though no known decoder or player honors them. Personal Computers were not required to include SCMS in the US. History SCMS was created as a compromise betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copy Protection
Copy protection, also known as content protection, copy prevention and copy restriction, is any measure to enforce copyright by preventing the reproduction of software, films, music, and other media. Copy protection is most commonly found on videotapes, DVDs, Blu-ray discs, HD-DVDs, computer software discs, video game discs and cartridges, audio CDs and some VCDs. It also may be incorporated into digitally distributed versions of media and software. Some methods of copy protection have also led to criticism because it caused inconvenience for paying consumers or secretly installed additional or unwanted software to detect copying activities on the consumer's computer. Making copy protection effective while protecting consumer rights remains a problem with media publication. Terminology Media corporations have always used the term copy protection, but critics argue that the term tends to sway the public into identifying with the publishers, who favor restriction technolog ...

Digital Media
In mass communication, digital media is any media (communication), communication media that operates in conjunction with various encoded machine-readable data formats. Digital content can be created, viewed, distributed, modified, listened to, and preserved on a digital electronic device, including digital data storage media (in contrast to analog electronic media) and digital broadcasting. ''Digital'' is defined as any data represented by a series of digits, and ''media'' refers to methods of broadcasting or communicating this information. Together, ''digital media'' refers to mediums of digitized information broadcast through a screen and/or a speaker. This also includes text, audio, video, and graphics that are transmitted over the internet for viewing or listening to on the internet. Digital media platforms, such as YouTube, Kick (service), Kick, and Twitch (service), Twitch, accounted for viewership rates of 27.9 billion hours in 2020.

Copy Control Information
Copy Control Information (CCI) is a two byte flag included in digital television streams that allows content owners and cable operators to specify how content can be duplicated. Originally defined as part of the 5C copy protection specification devised by DTCP working group back in 1998, it was later defined as part of the FCCs Plug and Play agreement in 2003. The two most used flags used are Copy Freely and Copy Once. Copy Freely is essentially no flag at all, while Copy Once means that a DVR can make one copy, but no more copies can be made. DVR platforms such as TiVo and Windows Media Center are responsible for reading the flag, decrypting the stream if necessary and storing the content in a way that enforces the flag set. A show that is marked Copy Once cannot be transferred to another TiVo via the Multi-Room Viewing feature and can not be transferred to the computer via TiVoToGo. In regard to Windows Media Center, shows marked Copy Once can only be played on the same PC in wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Flag
A broadcast flag is a bit field sent in the data stream of a digital television program that indicates whether or not the data stream can be recorded, or if there are any restrictions on recorded content. Possible restrictions include the inability to save an unencrypted digital program to a hard disk or other non-volatile storage, inability to make secondary copies of recorded content (in order to share or archive), forceful reduction of quality when recording (such as reducing high-definition television, high-definition video to the resolution of standard-definition television, standard TVs), and inability to skip over advertisement, commercials. In the United States, new television ATSC tuner, receivers using the ATSC standard were supposed to incorporate this functionality by July 1, 2005. The requirement was successfully contested in 2005 and rescinded in 2011. FCC ruling Officially called "Digital Broadcast Television Redistribution Control," the FCC's rule is in 47 CFR 7 ...

CD Recorder
In computing, an optical disc drive (ODD) is a disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, while other drives can both read and record. Those drives are called burners or writers since they physically burn the data onto the discs. Compact discs, DVDs, and Blu-ray discs are common types of optical media which can be read and recorded by such drives. Although most laptop manufacturers no longer have optical drives bundled with their products, external drives are still available for purchase separately. Drive types Some drives can only read data where as others can both read data and write data to writable discs. Drives which can read but not write data are "-ROM" (read-only memory) drives, even if they can read from writable formats such as "-R" and "-RW". Some drives have mixed read and write capabil ...

Private Copying Levy
A private copying levy (also known as blank media tax or levy) is a government-mandated scheme in which a special tax or levy (additional to any general sales tax) is charged on purchases of recordable media. Such taxes are in place in various countries and the income is typically allocated to the developers of "content". (A distinction is sometimes made between "tax" and "levy" based on the recipient of the accumulated funds; taxes are received by a government, while levies are received by a private body, such as a copyright collective.) Levy system may operate in principle as a system of collectivisation, partially replacing a property approach of sale of individual units. History Such levies were first introduced in Germany in the 1960s. With the advent of the audio cassette, legislators were persuaded that cassette recorders would decimate sales of records as friend after friend would then make copies of only one purchased album. Levies today are assessed on recordabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio Home Recording Act
The Audio Home Recording Act of 1992 (AHRA) amended the United States copyright law by adding Chapter 10, "Digital Audio Recording Devices and Media". The act enabled the release of recordable digital formats such as Sony's Digital Audio Tape without fear of contributory copyright infringement, contributory infringement lawsuits. The RIAA and music publishers, concerned that consumers' ability to make perfect digital copies of music would destroy the market for audio recordings, had threatened to sue companies and had lobbied Congress to pass legislation imposing mandatory copy protection technology and royalties on devices and media. The AHRA establishes a number of important precedents in US copyright law that defined the debate between device makers and the content industry for the ensuing two decades. These include: * the first government technology mandate in the copyright law, requiring all digital audio recording devices sold, manufactured or imported in the US (excluding pr ...
