CoreAVC
CoreAVC was a proprietary codec for decoding the H.264/MPEG-4 AVC (Advanced Video Coding) video format. In 2010, when CoreAVC was a software-only decoder, it was one of the fastest software decoders, but still slower than hardware-based ones. CoreAVC supports all H.264 Profiles except for 4:2:2 and 4:4:4. From 2009, CoreAVC introduced support to two forms of GPU hardware acceleration for H.264 decoding on Windows: CUDA (Nvidia only, in 2009) and DXVA (Nvidia and ATI GPUs, in 2011). CoreAVC was included as a part of the CorePlayer Multimedia Framework and was being used in the now defunct desktop client by Joost a system that was distributing videos over the Internet using peer-to-peer TV technology. CoreAVC-For-Linux DMCA complaint An open-source project named CoreAVC-For-Linux hosted at Google Code patches the loader code in the open source media player program MPlayer and allows it to use the Windows only CoreAVC DirectShow filter in free software environments.

DXVA
DirectX Video Acceleration (DXVA) is a Microsoft API specification for the Microsoft Windows and Xbox 360 platforms that allows video decoding to be hardware-accelerated. The pipeline allows certain CPU-intensive operations such as iDCT, motion compensation and deinterlacing to be offloaded to the GPU. DXVA 2.0 allows more operations, including video capturing and processing operations, to be hardware-accelerated as well. DXVA works in conjunction with the video rendering model used by the video card. DXVA 1.0, which was introduced as a standardized API with Windows 2000 and is currently available on Windows 98 or later, can use either the overlay rendering mode or VMR 7/9. DXVA 2.0, available only on Windows Vista, Windows 7, Windows 8 and later OSs, integrates with Media Foundation (MF) and uses the Enhanced Video Renderer (EVR) present in MF. Overview The DXVA is used by software video decoders to define a codec-specific pipeline for hardware-accelerated decoding and rend ...

Joost
Joost () was an Internet TV service, created by Niklas Zennström and Janus Friis (founders of Skype and Kazaa). During 2007–2008 Joost used peer-to-peer TV (P2PTV) technology to distribute content to their Mozilla-based desktop player; in late 2008 this was migrated to use a Flash-based Web player instead. Joost began development in 2006. Working under the code name "The Venice Project", Zennström and Friis assembled teams of some 150 software developers in about six cities around the world, including New York City, London, Leiden and Toulouse. According to Zennström at a 25 July 2007 press conference about Skype held in Tallinn, Estonia, Joost had signed up more than a million beta testers, and its launch was scheduled for the end of 2007. The team signed up with Warner Music, Indianapolis Motor Speedway Productions (Indianapolis 500, IndyCar Series) and production company Endemol for the beta.Orlowski, Andrew (17 January 2007)Joost – the new, new TV thing.''The Registe ...

ANSI C
ANSI C, ISO C, and Standard C are successive standards for the C programming language published by the American National Standards Institute (ANSI) and ISO/IEC JTC 1/SC 22/WG 14 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Historically, the names referred specifically to the original and best-supported version of the standard (known as C89 or C90). Software developers writing in C are encouraged to conform to the standards, as doing so helps portability between compilers. History and outlook The first standard for C was published by ANSI. Although this document was subsequently adopted by ISO/IEC and subsequent revisions published by ISO/IEC have been adopted by ANSI, "ANSI C" is still used to refer to the standard. While some software developers use the term ISO C, others are standards-body neutral and use Standard C. Standardizing C In 1983, the American National Standards Institute formed a committee, ...

PowerPC
PowerPC (with the backronym Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple Inc., Apple–IBM–Motorola alliance, known as AIM alliance, AIM. PowerPC, as an evolving instruction set, has been named Power ISA since 2006, while the old name lives on as a trademark for some implementations of Power Architecture–based processors. PowerPC was the cornerstone of AIM's PReP and Common Hardware Reference Platform (CHRP) initiatives in the 1990s. Originally intended for personal computers, the architecture is well known for being used by Apple's Power Macintosh, PowerBook, iMac, iBook, eMac, Mac Mini, and Xserve lines from 1994 until 2005, when Mac transition to Intel processors, Apple migrated to Intel's x86. It has since become a niche in personal computers, but remains popular for embedded system, embedded and high-performanc ...

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. It is essentially the process of opening up or dissecting a system to see how it works, in order to duplicate or enhance it. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: Information extraction, Modeling, and Review. Information extraction refers to the practice of gathering all relevant information for performing the operation. Modeling refers to th ...

Chilling Effects (group)
Lumen, formerly Chilling Effects, is an American collaborative archive created by Wendy Seltzer and founded along with several law school clinics and the Electronic Frontier Foundation to protect lawful online activity from legal threats. Lumen is a "project" of the Berkman Klein Center. Its website, ''Chilling Effects Clearinghouse'', allows recipients of cease-and-desist notices to submit them to the site and receive information about their legal rights and responsibilities. Founded in 2001 in San Francisco, California, it later moved its operations to Massachusetts. Inception The archive was founded in 2001 by Internet activists who were concerned that the unregulated private practice of sending cease-and-desist letters seemed to be increasing and was having an unstudied, but potentially significant, "chilling effect" on free speech. The archive got a boost when Google began submitting its notices to the site in 2002. Google began to do so in response to the publicity gen ...

DMCA
The Digital Millennium Copyright Act (DMCA) is a 1998 United States copyright law that implements two 1996 treaties of the World Intellectual Property Organization (WIPO). It criminalizes production and dissemination of technology, devices, or services intended to circumvent measures that control access to copyrighted works (commonly known as digital rights management or DRM). It also criminalizes the act of circumventing an access control, whether or not there is actual infringement of copyright itself. In addition, the DMCA heightens the penalties for copyright infringement on the Internet. Passed on October 12, 1998, by a unanimous vote in the United States Senate and signed into law by President Bill Clinton on October 28, 1998, the DMCA amended Title 17 of the United States Code to extend the reach of copyright, while limiting the liability of the providers of online services for copyright infringement by their users. The DMCA's principal innovation in the field of copyri ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Xine
xine is a multimedia playback engine for Unix-like operating systems released under the GNU General Public License. xine is built around a shared library (xine-lib) that supports different frontend player applications. xine uses libraries from other projects such as liba52, libmpeg2, FFmpeg, libmad, FAAD2, and Ogle. xine can also use binary Windows codecs through a wrapper, bundled as the w32codecs, for playback of some media formats that are not handled natively. History xine was started in 2000 by Günter Bartsch shortly after LinuxTag. At that time playing DVDs in Linux was described as a tortuous process since one had to manually create audio and video named pipes and start their separated decoder processes. Günter realized the OMS (Open Media System) or LiViD approach had obvious shortcomings in terms of audio and video synchronization, so xine was born as an experiment trying to get it right. The project evolved into a modern media player multi-threaded architec ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

HTPC
A home theater PC (HTPC) or media center computer is a technological convergence, convergent device that combines some or all the capabilities of a personal computer with a software application that focuses on video, photo, audio playback, and sometimes digital video recorder, video recording functionality. Since the mid-2000s, other types of consumer electronics, including Video game console, game consoles and dedicated media devices, have crossed over to manage video and music content. The term "media center" also refers to specialized application software designed to run on standard personal computers. HTPC and other convergent devices integrate components of a Home cinema, home theater into a unit co-located with a home entertainment system. An HTPC system typically has a remote control and the software interface normally has a 10-foot user interface, 10-foot (3 m) user interface design so that it can be comfortably viewed at typical television viewing distances.
