VideoCipher Back
VideoCipher is a brand name of analog scrambling and de-scrambling equipment for cable and satellite television invented primarily to enforce Television receive-only (TVRO) satellite equipment to only receive TV programming on a subscription basis. The second version of Videocipher, Videocipher II, was the primary encryption scheme used by major cable TV programmers to prevent TVRO owners from receiving free terrestrial television programming. It was especially notable due to the widespread compromise of its encryption scheme. Background Satellite providers Though the first half of the 1980s, HBO, Cinemax and other premium television providers with analog satellite transponders faced a fast growing market of TVRO equipment owners. Satellite television consumers could watch these services simply by pointing their dish at a satellite, and tuning into the provider's transponder. Two open questions existed about this practice: whether the Communications Act of 1934 applied as a ca ...

General Instruments VideoCipher II 2100E Satellite Descrambler
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of ''captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks. It has a NATO rank scal ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Telstar 301
Telstar 301 is an American communications satellite launched in July 1983 and operated by AT&T. It was one of three Telstar 3 satellites, followed by Telstar 302 in 1984 and Telstar 303 in 1985. The satellite served as the east coast home satellite for the ABC network from 1984 to 1993. The CBS network also used the satellite from 1985 to 1993. It also served as the first home of Fox Broadcasting Company until the late 1980s. Other entities that also used the satellite included Group W, Wold/Keystone Communications (which used the satellite to feed Paramount Television's syndicated output including ''Entertainment Tonight'', '' Star Trek: The Next Generation'', and '' Star Trek: Deep Space Nine''), Compact Video, Lorimar-Telepictures, and Warner Bros. Television Warner Bros. Television Studios (operating under the name Warner Bros. Television; formerly known as Warner Bros. Television Division) is an American television production and distribution studio of the Warner Br ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Data Encryption Standard
The Data Encryption Standard (DES ) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in the advancement of cryptography. Developed in the early 1970s at IBM and based on an earlier design by Horst Feistel, the algorithm was submitted to the National Bureau of Standards (NBS) following the agency's invitation to propose a candidate for the protection of sensitive, unclassified electronic government data. In 1976, after consultation with the National Security Agency (NSA), the NBS selected a slightly modified version (strengthened against differential cryptanalysis, but weakened against brute-force attacks), which was published as an official Federal Information Processing Standard (FIPS) for the United States in 1977. The publication of an NSA-approved encryption standard led to its quick international adoption and widespread academic scrutiny. ...

Pirate Decryption
Pirate decryption is the decryption, or decoding, of pay TV or pay radio signals without permission from the original broadcaster. The term "pirate" is used in the sense of copyright infringement. The MPAA and other groups which lobby in favour of intellectual property (specifically copyright and trademark) regulations have labelled such decryption as "signal theft" even though there is no direct tangible loss on the part of the original broadcaster, arguing that losing out on a potential chance to profit from a consumer's subscription fees counts as a loss of actual profit. History The concept of pay TV or pay television involves a broadcaster deliberately transmitting signals in a non-standard, scrambled or encrypted format in order to charge viewers a subscription fee for the use of a special decoder needed to receive the scrambled broadcast signal. Early pay TV broadcasts in countries such as the United States used standard over-the-air transmitters; many restrictions ap ...

Galaxy 1
Galaxy 1 was the first in a line of Galaxy communications satellites launched by Hughes Communications in 1983. It helped fill a hole in satellite broadcasting bandwidth created by the loss of RCA's Satcom 3 in 1979. Unlike satellite owners RCA and Western Union, Hughes did not lease time on their transponders in the fashion of a common carrier, but instead sold transponders outright to content providers. This created a stable lineup of content attractive enough for cable providers to dedicate Earth station receivers to it full-time. Among the services on Galaxy 1 by mid-1984: HBO, Cinemax, The Movie Channel, Showtime, The Disney Channel, TBS, CNN, ESPN, and The Nashville Network. Retirement of Galaxy 1 In 1992, Galaxy 1 was replaced by Galaxy 5 as the predominant cable television signal carrier, when a majority of satellite television services were relocated onto that satellite. It was originally slated for retirement in 1992 and replacement by Galaxy 1R, but the re ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fox Broadcasting Company
The Fox Broadcasting Company, commonly known simply as Fox and stylized in all caps as FOX, is an American commercial broadcast television network owned by Fox Corporation and headquartered in New York City, with master control operations and additional offices at the Fox Network Center in Los Angeles and the Fox Media Center in Tempe. Launched as a competitor to the Big Three television networks ( ABC, CBS, and NBC) on October 9, 1986, Fox went on to become the most successful attempt at a fourth television network. It was the highest- rated free-to-air network in the 18–49 demographic from 2004 to 2012 and again in 2020, and was the most-watched American television network in total viewership during the 2007–08 season. Fox and its affiliated companies operate many entertainment channels in international markets, but these do not necessarily air the same programming as the U.S. network. Most viewers in Canada have access to at least one U.S.-based Fox affiliate, either ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Teletext
A British Ceefax football index page from October 2009, showing the three-digit page numbers for a variety of football news stories Teletext, or broadcast teletext, is a standard for displaying text and rudimentary graphics on suitably equipped television sets. Teletext sends data in the broadcast signal, hidden in the invisible vertical blanking interval area at the top and bottom of the screen. The teletext decoder in the television buffers this information as a series of "pages", each given a number. The user can display chosen pages using their remote control. In broad terms, it can be considered as Videotex, a system for the delivery of information to a user in a computer-like format, typically displayed on a television or a dumb terminal, but that designation is usually reserved for systems that provide bi-directional communication, such as Prestel or Minitel. Teletext was created in the United Kingdom in the early 1970s by John Adams, Philips' lead designer for video di ...

Closed-captioning
Closed captioning (CC) and subtitling are both processes of displaying text on a television, video screen, or other visual display to provide additional or interpretive information. Both are typically used as a transcription of the audio portion of a program as it occurs (either verbatim or in edited form), sometimes including descriptions of non-speech elements. Other uses have included providing a textual alternative language translation of a presentation's primary audio language that is usually burned-in (or "open") to the video and unselectable. HTML5 defines subtitles as a "transcription or translation of the dialogue when sound is available but not understood" by the viewer (for example, dialogue in a foreign language) and captions as a "transcription or translation of the dialogue, sound effects, relevant musical cues, and other relevant audio information when sound is unavailable or not clearly audible" (for example, when audio is muted or the viewer is deaf or hard of ...
