Advanced Systems FormatAdvanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietarydigital audio/digital videocontainer format, especially meant for streaming media. ASF is part of the Media Foundation framework. Overview and featuresASF is based on serializedobjects which are essentially byte sequences identified by a GUID marker.
Video codecA video codec is software or hardware that compresses and decompresses digital video. In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder. The compressed data format usually conforms to a standard video coding format.
Container formatA container format (informally, sometimes called a wrapper) or metafile is a file format that allows multiple data streams to be embedded into a single file, usually along with metadata for identifying and further detailing those streams. Notable examples of container formats include archive files (such as the ZIP format) and formats used for multimedia playback (such as Matroska, MP4, and AVI).RealVideoRealVideo, also spelled as Real Video, is a suite of proprietaryvideo compression formats developed by RealNetworks — the specific format changes with the version. It was first released in 1997 and as of 2024 was at version 15. RealVideo is supported on many platforms, including Windows, Mac, Linux, Solaris, and several mobile phones. RealVideo is usually paired with RealAudio and packaged in a RealMedia (.rm) container.Video coding formatA video coding format (or sometimes video compression format) is an encoded format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation. A computer software or hardware component that compresses or decompresses a specific video coding format is a video codec.
Digital rights managementDigital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures, such as access control technologies, can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification and distribution of copyrighted works (e.g. software, multimedia content) and of systems that enforce these policies within devices.Windows MediaWindows Media is a discontinued multimedia framework for media creation and distribution for Microsoft Windows. It consisted of a software development kit (SDK) with several application programming interfaces (API) and a number of prebuilt technologies, and is the replacement of NetShow technologies. The Windows Media SDK was replaced by Media Foundation when Windows Vista was released in 2007.VC-1SMPTE 421, informally known as VC-1, is a video coding format. Most of it was initially developed as Microsoft's proprietary video format Windows Media Video 9 in 2003. With some enhancements including the development of a new Advanced Profile, it was officially approved as an SMPTE standard on April 3, 2006. It was primarily marketed as a lower-complexity competitor to the H.264/MPEG-4 AVC standard.
HD DVDHD DVD (short for High Density Digital Versatile Disc) is an obsolete high-density optical disc format for storing data and playback of high-definition video. Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format, but lost out to Blu-ray, which was supported by Sony and others.
MicrosoftMicrosoft Corporation is an American multinational technology company headquartered in Redmond, Washington. The company became influential in the rise of personal computers through software like Windows and has since expanded into areas such as Internet services, cloud computing, artificial intelligence, video gaming, and more.Society of Motion Picture and Television EngineersThe Society of Motion Picture and Television Engineers (SMPTE) (, rarely ), founded by Charles Francis Jenkins in 1916 as the Society of Motion Picture Engineers or SMPE, is a global professional association of engineers, technologists, and executives working in the media and entertainment industry.
Blu-rayDigital optical disc formatBlu-ray (Blu-ray Disc or BD) is a digitaloptical discdata storage format designed to supersede the DVD format. It was invented and developed in the early-mid 2000s and released worldwide on June 20, 2006, capable of storing several hours of high-definition video (HDTV720p and 1080p).*As an Amazon Associate I earn from qualifying purchases.
