Riplock
Riplock is a firmware component of some computer DVD and Blu-ray drives that enforces a speed ceiling below a drive's physical capabilities (typically 2×) when DVD-Video or BDMV data is being read. CDs are usually not affected, nor are DVDs or Blu-rays not authored as videodiscs. Riplock's stated purpose is to reduce noise during video playback by preventing a drive from spinning up faster than would be necessary to read a standards-compliant disc. It has been asserted that Riplock is also (or solely) intended to deter video ripping (specifically illicit ripping of copyrighted content, i.e., piracy) by making the process artificially time-consuming. For example, a feature film pressed on a dual-layer Blu-ray (the most common variant for commercial movies) can take up to 90 minutes to rip at 2×, while ripping the same film without Riplock would take half an hour or less even with a power-limited slim drive (and potentially as little as 12 minutes with a modern half-height dr ...

DVD-Video
DVD-Video is a consumer video format used to store digital video on DVD discs. DVD-Video was the dominant consumer home video format in Asia, North America, Europe, and Australia in the 2000s until it was supplanted by the high-definition Blu-ray Disc. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e.g., a DVD player, or a computer DVD drive with a software DVD player). Commercial DVD movies are encoded using a combination MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below). Typically, the data rate for DVD movies ranges from 3 to 9.5 Mbit/s, and the bit rate is usually adaptive. DVD-Video was first available in Japan on November 1, 1996 (with major releases beginning December 20, 1996), followed by a release on March 24, 1997 in the United States—to line up with the 69th Academy Awards that same day. The DVD-Video specification was created by DVD Forum and can be obtained from DVD For ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ripping
Ripping is extracting all or parts of digital content from a container. Originally, it meant to rip music out of Commodore 64 games. Later, the term was used to extract WAV or MP3 format files from digital audio CDs, but got applied as well to extract the contents of any media, including DVD and Blu-ray discs, and video game sprites. Despite the name, neither the media nor the data is damaged after extraction. Ripping is often used to shift formats, and to edit, duplicate or back up media content. A rip is the extracted content, in its destination format, along with accompanying files, such as a cue sheet or log file from the ripping software. To rip the contents out of a container is different from simply copying the whole container or a file. When creating a copy, nothing looks into the transferred file, nor checks if there is any encryption or not, and raw copy is also not aware of any file format. One can copy a DVD byte by byte via programs like the Linux dd command onto ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Firmware
In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems (running embedded software), home and personal-use appliances, computers, and computer peripherals. Firmware is held in non-volatile memory devices such as ROM, EPROM, EEPROM, and flash memory. Updating firmware requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Some firmware memory devices are permanently installed and cannot be changed after manufacture. C ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Blu-ray
The Blu-ray Disc (BD), often known simply as Blu-ray, is a digital optical disc data storage format. It was invented and developed in 2005 and released on June 20, 2006 worldwide. It is designed to supersede the DVD format, and capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X. The name "Blu-ray" refers to the blue laser (which is actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs. The polycarbonate disc is in diameter and thick, the same size as DVDs and CDs. Conventional or pre-BD-XL Blu-ray Discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-l ...

Optical Disc Authoring
Optical disc authoring, including DVD and Blu-ray Disc authoring, is the process of assembling source material—video, audio or other data—into the proper logical volume format to then be recorded ("burned") onto an optical disc (typically a compact disc or DVD). Process To burn an optical disc, one usually first creates an optical disc image with a full file system, of a type designed for the optical disc, in temporary storage such as a file in another file system on a disk drive. One may test the image on target devices using rewriteable media such as CD-RW, DVD±RW and BD-RE. Then, one copies the image to the disc (usually write-once media for hard distribution). Most optical disc authoring utilities create a disc image and copy it to the disc in one bundled operation, so that end-users often do not know the distinction between creating and burning. However, it is useful to know because creating the disc image is a time-consuming process, while copying the imag ...

Copyright
A copyright is a type of intellectual property that gives its owner the exclusive right to copy, distribute, adapt, display, and perform a creative work, usually for a limited time. The creative work may be in a literary, artistic, educational, or musical form. Copyright is intended to protect the original expression of an idea in the form of a creative work, but not the idea itself. A copyright is subject to limitations based on public interest considerations, such as the fair use doctrine in the United States. Some jurisdictions require "fixing" copyrighted works in a tangible form. It is often shared among multiple authors, each of whom holds a set of rights to use or license the work, and who are commonly referred to as rights holders. These rights frequently include reproduction, control over derivative works, distribution, public performance, and moral rights such as attribution. Copyrights can be granted by public law and are in that case considered "territorial righ ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Copyright Infringement
Copyright infringement (at times referred to as piracy) is the use of works protected by copyright without permission for a usage where such permission is required, thereby infringing certain exclusive rights granted to the copyright holder, such as the right to reproduce, distribute, display or perform the protected work, or to make derivative works. The copyright holder is typically the work's creator, or a publisher or other business to whom copyright has been assigned. Copyright holders routinely invoke legal and technological measures to prevent and penalize copyright infringement. Copyright infringement disputes are usually resolved through direct negotiation, a notice and take down process, or litigation in civil court. Egregious or large-scale commercial infringement, especially when it involves counterfeiting, is sometimes prosecuted via the criminal justice system. Shifting public expectations, advances in digital technology and the increasing reach of the Internet ...

Feature Film
A feature film or feature-length film is a narrative film (motion picture or "movie") with a running time long enough to be considered the principal or sole presentation in a commercial entertainment program. The term ''feature film'' originally referred to the main, full-length film in a cinema program that included a short film and often a newsreel. Matinee programs, especially in the US and Canada, in general, also included cartoons, at least one weekly serial and, typically, a second feature-length film on weekends. The first narrative feature film was the 60-minute ''The Story of the Kelly Gang'' (1906, Australia). Other early feature films include ''Les Misérables'' (1909, U.S.), ''L'Inferno'', ''Defence of Sevastopol'' (1911), '' Oliver Twist'' (American version), '' Oliver Twist'' (British version), '' Richard III'', ''From the Manger to the Cross'', ''Cleopatra'' (1912), '' Quo Vadis?'' (1913), ''Cabiria'' (1914) and ''The Birth of a Nation'' (1915). Description The ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Drive Bay
A drive bay is a standard-sized area for adding hardware to a computer. Most drive bays are fixed to the inside of a case, but some can be removed. Over the years since the introduction of the IBM PC, it and its compatibles have had many form factors of drive bays. Four form factors are in common use today, the 5.25-inch, 3.5-inch, 2.5-inch or 1.8-inch drive bays. These names do not refer to the width of the bay itself, but rather to the width of the disks used by the drives mounted in these bays. Form factors 8.0-inch ''8.0-inch'' drive bays were found in early IBM computers, CP/M computers, and the TRS-80 Model II. They were high, wide, and approximately deep, and were used for hard disk drives and floppy disk drives. This form factor is obsolete. 5.25-inch ''5.25-inch'' drive bays are divided into two height specifications, ''full-height'' and ''half-height''. ''Full-height'' bays were found in old PCs in the early to mid-1980s. They were high, wide, and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Patch (computing)
A patch is a set of changes to a computer program or its supporting data designed to update, fix, or improve it. This includes fixing security vulnerabilities and other bugs, with such patches usually being called bugfixes or bug fixes. Patches are often written to improve the functionality, usability, or performance of a program. The majority of patches are provided by software vendors for operating system and application updates. Patches may be installed either under programmed control or by a human programmer using an editing tool or a debugger. They may be applied to program files on a storage device, or in computer memory. Patches may be permanent (until patched again) or temporary. Patching makes possible the modification of compiled and machine language object programs when the source code is unavailable. This demands a thorough understanding of the inner workings of the object code by the person creating the patch, which is difficult without close study of the sourc ...

Warranty
In contract law, a warranty is a promise which is not a condition of the contract or an innominate term: (1) it is a term "not going to the root of the contract",Hogg M. (2011). ''Promises and Contract Law: Comparative Perspectives''p. 48 Cambridge University Press. and (2) which only entitles the innocent party to damages if it is breached: i.e. the warranty is not true or the defaulting party does not perform the contract in accordance with the terms of the warranty. A warranty is not a guarantee. It is a mere promise. It may be enforced if it is breached by an award for the legal remedy of damages. A warranty is a term of a contract. Depending on the terms of the contract, a product warranty may cover a product such that a manufacturer provides a warranty to a consumer with which the manufacturer has no direct contractual relationship. A warranty may be express or implied. An express warranty is expressly stated (typically, written); whether or not a term will be implied int ...
