Video Encoded Invisible Light
Video Encoded Invisible Light (VEIL) is a technology for encoding low-bandwidth digital data bitstream in video signal, developed by VEIL Interactive Technologies. VEIL is compatible with multiple formats of video signals, including PAL, SECAM, and NTSC. The technology is based on a steganographically encoded data stream in the luminance of the videosignal. A recent application of VEIL, the VEIL Rights Assertion Mark (VRAM or V-RAM) is a copy-restriction signal that can be used to ask devices to apply DRM technology. This has been seen as analogous to the broadcast flag. It is also known as "CGMS-A plus VEIL" and "broadcast flag on steroids." There are two versions of VEIL on the market: * VEIL-I, or VEIL 1, has raw speed of 120 bits per second. It is used for unidirectional communication (TV→devices) with simple devices or toys, and to deliver coupons with TV advertising. It manipulates the luminance of the video signal in ways difficult to perceive to human eye. * VEIL-I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitstream
A bitstream (or bit stream), also known as binary sequence, is a sequence of bits. A bytestream is a sequence of bytes. Typically, each byte is an 8-bit quantity, and so the term octet stream is sometimes used interchangeably. An octet may be encoded as a sequence of 8 bits in multiple different ways (see bit numbering) so there is no unique and direct translation between bytestreams and bitstreams. Bitstreams and bytestreams are used extensively in telecommunications and computing. For example, synchronous bitstreams are carried by SONET, and Transmission Control Protocol transports an asynchronous bytestream. Relationship between bitstreams and bytestreams In practice, bitstreams are not used directly to encode bytestreams; a communication channel may use a signalling method that does not directly translate to bits (for instance, by transmitting signals of multiple frequencies) and typically also encodes other information such as framing and error correction together wi ...

Spread Spectrum
In telecommunication and radio communication, spread-spectrum techniques are methods by which a signal (e.g., an electrical, electromagnetic, or acoustic signal) generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference, noise, and jamming, to prevent detection, to limit power flux density (e.g., in satellite downlinks), and to enable multiple-access communications. Telecommunications Spread spectrum generally makes use of a sequential noise-like signal structure to spread the normally narrowband information signal over a relatively wideband (radio) band of frequencies. The receiver correlates the received signals to retrieve the original information signal. Originally there were two motivations: either to resist enemy efforts to jam the communications ( ...

Copy Protection
Copy protection, also known as content protection, copy prevention and copy restriction, describes measures 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. 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 technologies, rather than with the users. Copy prevention and copy control may be more neutral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rights Assertion Mark
Rights are legal, social, or ethical principles of freedom or entitlement; that is, rights are the fundamental normative rules about what is allowed of people or owed to people according to some legal system, social convention, or ethical theory. Rights are of essential importance in such disciplines as law and ethics, especially theories of justice and deontology. Rights are fundamental to any civilization and the history of social conflicts is often bound up with attempts both to define and to redefine them. According to the ''Stanford Encyclopedia of Philosophy'', "rights structure the form of governments, the content of laws, and the shape of morality as it is currently perceived". Definitional issues One way to get an idea of the multiple understandings and senses of the term is to consider different ways it is used. Many diverse things are claimed as rights: There are likewise diverse possible ways to categorize rights, such as: There has been considerable debate a ...

Vertical Blanking Interval
In a raster scan display, the vertical blanking interval (VBI), also known as the vertical interval or VBLANK, is the time between the end of the final visible line of a frame or field and the beginning of the first visible line of the next frame. It is present in analog television, VGA, DVI and other signals. In raster cathode ray tube displays, the blank level is usually supplied during this period to avoid painting the retrace line — see raster scan for details; signal sources such as television broadcasts do not supply image information during the blanking period. Digital displays usually will not display incoming data stream during the blanking interval even if present. The VBI was originally needed because of the inductive inertia of the magnetic coils which deflect the electron beam vertically in a CRT; the magnetic field, and hence the position being drawn, cannot change instantly. Additionally, the speed of older circuits was limited. For horizontal deflection, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrovision
TiVo Corporation, formerly known as the Rovi Corporation and Macrovision Solutions Corporation, was an American technology company. Headquartered in San Jose, California, the company is primarily involved in licensing its intellectual property within the consumer electronics industry, including digital rights management, electronic program guide software, and metadata. The company holds over 6,000 pending and registered patents. The company also provides analytics and recommendation platforms for the video industry.

Digital Content Security Act
The United States The Digital Transition Content Security Act (DTCSA, ) was a bill introduced by House Judiciary Committee Chairman James Sensenbrenner Jr., a Wisconsin Republican, on December 16, 2005. The bill was backed by Democratic Rep. John Conyers. Its goal is " require certain analog conversion devices to preserve digital content security measures", i.e. plugging the analog hole. The bill effectively proposes mandating of the VEIL Rights Assertion Mark technology into new video-handling consumer devices. The bill was referred to subcommittee in 2006 and no further action seems to have been taken since then. Advocates MPAA Chairman Dan Glickman applauded the bill, saying it was a "''very important piece of legislation that will promote more consumer choice as it protects copyright owners in the digital age.''" Critics Public Knowledge President Gigi Sohn testified before the House Judiciary Committee (United States House Judiciary Subcommittee on Courts, the Internet, ...

Analog Hole
The analog hole (also known as the analog loophole or analog gap) is a perceived fundamental and inevitable vulnerability in copy protection schemes for noninteractive works in digital formats which can be exploited to duplicate copy-protected works using analog means. Once digital information is converted to a human-perceptible (analog) form, it is a relatively simple matter to digitally recapture that analog reproduction in an unrestricted form, thereby fundamentally circumventing any and all restrictions placed on copyrighted digitally distributed work. Media publishers who use digital rights management (DRM), to restrict how a work can be used, perceive the necessity to make it visible or audible as a "hole" in the control that DRM otherwise affords them. Overview Although the technology for creating digital recordings from analog sources has existed for some time, it was not necessarily viewed as a "hole" until the widespread deployment of DRM in the late 1990s. However, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foster's Lager
Foster's Lager is an internationally-distributed brand of lager. It is owned by the international brewing group Asahi Group Holdings, and is brewed under licence in a number of countries, including its biggest market, the UK, where the European rights to the brand are owned by Heineken International. While Foster's is the largest-selling Australian beer brand in the world, it is not as popular and relatively rare compared with other beers in Australia, particularly when compared to other Carlton & United Breweries beers such as Victoria Bitter and Carlton Draught. History Foster's was created by two American brothers, William M. and Ralph R. Foster, who arrived in Melbourne from New York in 1886. The brothers began brewing Foster's Lager in November 1888. It was made available to the public from February 1889. The product was first exported in 1901, when bottles were sent to Australian combatants in the Boer War. In 1907, the company merged with five other brewing companie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toby Terrier
Toby Terrier was a toy dog manufactured in the early 1990s by Tiger Electronics. The toy was designed to make various comments and remarks when placed in front of a television playing one of the select PLUS videos from the ''Toby Terrier and His Video Pals'' video series. In order for this function to work a specific cartridge that matched up with the video being played would have to be inserted into the toy. His collar contained a sensor that tracked what was going on in the movie. It was activated by pressing a button located below the sensor. The Toby Terrier video series was a comical and educational video series for kids, whose characters consisted of dog puppets. The video series itself was known as ''Toby Terrier and His Video Pals''. How It Worked Toby would wag his tail, bark, nod his head and say phrases such as, "Well, scratch my fleas!" as one watched the video when he was turned on. This was accomplished using VEIL Technology. The video fields would send out a data s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batmobile
The Batmobile is the fictional car driven by the superhero Batman. Housed in the Batcave, which it accesses through a hidden entrance, the Batmobile is both a heavily armored tactical assault vehicle and a personalized custom-built pursuit and capture vehicle that is used by Batman in his fight against crime. Using the latest civilian performance technology, coupled with prototype military-grade hardware—most of which was developed by Wayne Enterprises—Batman creates an imposing hybrid monster car to prowl the streets of Gotham City. The Batmobile first appeared in '' Detective Comics'' #27 (May 1939), where it was depicted as an ordinary-looking red car. Its appearance has varied but, since its earliest appearances, the Batmobile has had a prominent bat motif, typically including wing-shaped tailfins. Armored in the early stages of Batman's career, it has been customized over time and is the most technologically advanced crime-fighting asset in Batman's arsenal. Depict ...

Action Figure
An action figure is a poseable character (arts), character model figure made most commonly of plastic, and often based upon characters from a film, comic book, military, video game or television program; fictional or historical. These figures are usually marketing, marketed toward boys and adult collectors. The term was coined by Hasbro in 1964 to market G.I. Joe to boys (while competitors called similar offerings ''boy's dolls''). According to a 2005 study in Sweden, action figures which display traditional Masculinity, masculine traits primarily target boys. While most commonly marketed as a child's toy, the action figure has gained widespread acceptance as collecting, collector item for adults. In such a case, the item may be produced and designed on the assumption it will be bought solely for display as a collectible and not played with like a child's toy. History Precursors Articulated dolls go back to at least 200 BCE, with articulated clay and wooden dolls of ancient ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
