Peer-to-peer
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network, forming a peer-to-peer network of Node (networking), nodes. In addition, a personal area network (PAN) is also in nature a type of Decentralized computing, decentralized peer-to-peer network typically between two devices. Peers make a portion of their resources, such as processing power, disk storage, or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model in which the consumption and supply of resources are divided. While P2P systems had previously been used in many application domains, the architecture was popularized by the Internet file sharing system Napster, originally released in ...

FairPlay
FairPlay is a family of digital rights management (DRM) technologies developed by Apple Inc. for protecting videos, books and apps and historically for music. Music The initial version of FairPlay was created to protect music on the iTunes Store, and is the only version of FairPlay that is no longer actively used. Technical details FairPlay is built into the MP4 multimedia file format as an encrypted AAC audio layer. FairPlay-protected files are regular MP4 container files with an encrypted AAC audio layer. The layer is encrypted using the AES algorithm. The master key required to decrypt the audio layer is also stored in encrypted form in the MP4 container file. The key required to decrypt the master key is called the "user key". When a user registers a new computer with iTunes, the device requests authorization from Apple's servers, thereby gaining a user key. Upon attempting to play a file, the master key stored within the file is then matched to the user key, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PlayReady
PlayReady is a media file copy prevention technology from Microsoft that includes encryption, output prevention and digital rights management (DRM). It was announced in February 2008. Technological differences The main differences relative to previous DRM schemes from Microsoft are: * Some popular features that were already present in other DRM schemes in the market have been added. These include the concept of domain (group of devices belonging to the same user which can share the same licenses), Embedded Licenses (licenses that are embedded in the content files, avoiding a separate step for license acquisition) and envelopes (the ability to DRM arbitrary, potentially non-media content). It is also the protection scheme for IIS Smooth Streaming, Microsoft's adaptive streaming technology. * It is platform-independent: unlike other Microsoft DRM schemes like Janus, PlayReady can be ported to any kind of portable device, even if it uses non-Microsoft technology ( OS, codecs, medi ...

Widevine
Widevine is a proprietary digital rights management (DRM) system that is included in most major web browsers and in the operating systems Android and iOS. It is used by streaming services such as Netflix, Amazon Prime, Hulu etc., to allow authorized users to view media while preventing them from creating unauthorized copies. Widevine was originally developed in 1999 by Internet Direct Media, who later rebranded as Widevine Technologies. Following several rounds of funding, the company was acquired by Google in 2010 for an undisclosed amount. History Origins (1998–2006) Widevine was created by Seattle-based Internet Direct Media in 1999 as Widevine Cypher. The company, founded by executive Brian Baker and cryptography researcher Jeremy Horwitz, changed its name to Widevine Technologies.

Speex
{{More citations needed, date=May 2025 The Speex project is an attempt to create a free software speech codec, unencumbered by patent restrictions. Speex is licensed under the BSD License and is used with the Xiph.org Foundation's Ogg container format. The Speex coder uses the Ogg bitstream format, and the Speex designers see their project as complementary to the Vorbis general-purpose audio compression project. Description Unlike many other speech codecs, Speex is not targeted at cell phones but rather at voice over IP (VoIP) and file-based compression. The design goals have been to make a codec that would allow both very good quality speech and low bit rate, which led to the development of a codec with multiple bit rates. Very good quality also meant the support of wideband (16 kHz sampling rate) in addition to narrowband (telephone quality, 8 kHz sampling rate). Designing for VoIP instead of cell phone use means that Speex must be robust to lost packets, but not to cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPEG-1 Audio Layer II
MP2 (formally MPEG-1 Audio Layer II or MPEG-2 Audio Layer II, sometimes incorrectly called Musicam) is a lossy audio compression format. It is standardised as one of the three audio codecs of MPEG-1 alongside MPEG-1 Audio Layer I (MP1) and MPEG-1 Audio Layer III (MP3). The MP2 abbreviation is also used as a common file extension for files containing this type of audio data, or its extended variant MPEG-2 Audio Layer II. MPEG-1 Audio Layer II was developed by Philips, CCETT and IRT as the MUSICAM algorithm, as part of the European-funded Digital Audio Broadcasting (DAB) project. Alongside its use on DAB broadcasts, the codec has been adopted as the standard audio format for Video CD and Super Video CD media, and also for HDV. On the other hand, MP3 (which was developed by a rival collaboration led by Fraunhofer Society called ASPEC) gained more widespread acceptance for PC and Internet applications. MP2 compresses less than MP3, but therefore also has less computational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Audio Coding
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. It was developed by Dolby, AT&T, Fraunhofer and Sony, originally as part of the MPEG-2 specification but later improved under MPEG-4.ISO (2006ISO/IEC 13818-7:2006 – Information technology — Generic coding of moving pictures and associated audio information — Part 7: Advanced Audio Coding (AAC), Retrieved on 2009-08-06ISO (2006, Retrieved on 2009-08-06 AAC was designed to be the successor of the MP3 format (MPEG-2 Audio Layer III) and generally achieves higher sound quality than MP3 at the same bit rate. AAC encoded audio files are typically packaged in an MP4 container most commonly using the filename extension .m4a. The basic profile of AAC (both MPEG-4 and MPEG-2) is called AAC-LC (''Low Complexity''). It is widely supported in the industry and has been adopted as the default or standard audio format on products including Apple's iTunes Store, Nintendo's Wii, DSi and ...

MPEG4
MPEG-4 is a group of international standards for the compression of digital audio and visual data, multimedia systems, and file storage formats. It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC 1/SC29/WG11) under the formal standard ISO/IEC 14496 – ''Coding of audio-visual objects''. Uses of MPEG-4 include compression of audiovisual data for Internet video and CD distribution, voice (telephone, videophone) and broadcast television applications. The MPEG-4 standard was developed by a group led by Touradj Ebrahimi (later the JPEG president) and Fernando Pereira. Background MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally specified digital ...

MPEG2
MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as H.264/AVC and H.265/HEVC, backwards compatibility with existing hardware and software means it is still widely used, for example in over-the-air digital television broadcasting and in the DVD-Video standard. Main characteristics MPEG-2 is widely used as the format of digital television signals that are broadcast by terrestrial (over-the-air), cable, and direct broadcast satellite TV systems. It also specifies the format of movies and other programs that are distributed on DVD and similar discs. TV stations, TV receivers, DVD players, and other equipment are ...
