The Descramble team was not the first to go digging for supercritical fluids.

The Descramble team started drilling Venelle-2 right around the time the Iceland Deep Drilling Project discovered supercritical fluids.

Samsung's new sensor will also be able to descramble the color filter for full-resolution 64-megapixel shots in good light.

In 2015, a consortium of European energy companies and research institutes launched the Descramble project to see if even more energy could be extracted from the geothermal field.

That said, these boxes could be reprogrammed to descramble premium channels and pay-per-view content, which made many of these modified units the backbone of the "black box" market that enabled service theft.

A descrambler is a device that unscrambles the encoded signal and restores the picture and sound of a scrambled channel. Typical modern cable boxes include some form of descrambling ability. Such a cable box must also be addressable (see below) in order to be told to descramble the signal for a given channel. Early electronic cable boxes, for example, could descramble channels that used signal inversion as a scrambling method.

The Zenith Phonevision system became the first home pay-per-view system to be tested in the United States. Developed in 1951, it used telephone lines to take and receive orders, as well as to descramble a television broadcast signal. The field tests conducted for Phonevision lasted for 90 days and were tested in Chicago, Illinois. The system used IBM punch cards to descramble a signal broadcast during the broadcast station's "off-time".

MULTI2 is a symmetric key algorithm with variable number of rounds. It has a block size of 64 bits, and a key size of 64 bits. A 256-bit implementation-dependent substitution box constant is used during key schedule. Scramble and descramble is done by repeating four basic functions (involutions).

With pay-per-view services, selected channels offer movies and special events such as sports or adult entertainment, for an additional fee, on a per-movie or per-program basis. A special addressable converter is furnished by the cable company to subscribers of this service. Through the use of special equipment, the cable company can direct the customer's cable box to descramble the program for which the fee was paid.

Apart from the notable successes of the German navy's decryption services, there were also some results from the other institutions. For example, the Reichspost was able to descramble scrambled voice transmission of the transatlantic telephone connection between the USA and Great Britain. For this purpose, an interception and descrambling facility was built in Noordwijk, in occupied Holland. From 1940, the Mail Service's descrambling specialists intercepted and understood classified telephone conversation between President Roosevelt and the British Prime Minister Winston Churchill.

The converter also receives the signal and compares information on the signal to corresponding authorization from the controller. Based on the comparison, the customer's STB may or may not be able to descramble the signal and view the content or Television Program. The Addressability system may be viewed as the interface between the billing system or BSS/OSS and the controller. Known Addressability systems receive information from the billing system and send it to the appropriate controller to enable the controller to properly configure the converter.

Block conversion of the entire affected frequency band onto UHF, while less common, was used by some models to provide full VCR compatibility and the ability to drive multiple TV sets, albeit with a somewhat nonstandard channel numbering scheme. Newer television receivers greatly reduced the need for external set-top boxes, although cable converter boxes continue to be used to descramble premium cable channels according to carrier-controlled access restrictions, and to receive digital cable channels, along with using interactive services like video on demand, pay per view, and home shopping through television.

The concept behind Phonevision involved making Hollywood films available to home viewers at $1 per movie (equivalent to $/movie after inflation). Viewers were required to purchase a descrambler unit that sat on top of the television, plugged into the TV's antenna leads and also into the telephone line. Someone wishing to view a movie would call the Phonevision operator, who would add them to the viewer queue. A signal sent via phone lines would allow the box to descramble the signal and at the end of the month, viewers would be billed for the movie on their regular telephone bill.

Old cable equipment used an analog signal that was scrambled by tuning the signal so the picture was unsteady, just as Macrovision does at an attempt to copy a video. The equipment would descramble the signal so that it can be viewed by the subscriber. It also is addressable, meaning that it can be remotely controlled by the company's technical staff. The first major case covered by the media was when 317 subscribers were caught in 1991 when the company they subscribed to sent a "bullet" (a video signal that turns off the equipment) to their cable boxes.

Descramble in cable television context is the act of taking a scrambled or encrypted video signal that has been provided by a cable television company for premium television services, processed by a scrambler and then supplied over a coaxial cable and delivered to the household where a set-top box reprocesses the signal, thus descrambling it and making it available for viewing on the television set. A descrambler is a device that restores the picture and sound of a scrambled channel. A descrambler must be used with a cable converter box to be able to unencrypt all of the premium & pay-per-view channels of a Cable Television System.

Section 103 (17 U.S.C Sec. 1201(a)(1)) of the DMCA states: > No person shall circumvent a technological measure that effectively controls > access to a work protected under this title. The Act defines what it means in Section 1201(a)(3): > (3) As used in this subsection— (A) to "circumvent a technological measure" > means to descramble a scrambled work, to decrypt an encrypted work, or > otherwise to avoid, bypass, remove, deactivate, or impair a technological > measure, without the authority of the copyright owner; and (B) a > technological measure "effectively controls access to a work" if the > measure, in the ordinary course of its operation, requires the application > of information, or a process or a treatment, with the authority of the > copyright owner, to gain access to the work. Thus, if there is some "technological measure that effectively controls access to a work", it is illegal to circumvent that measure.
