Windows Media
Windows Media is a discontinued multimedia framework for media creation and distribution for Microsoft Windows. It consists 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.

Windows Media Center
Windows Media Center (WMC) is a defunct digital video recorder and media player created by Microsoft. Media Center was first introduced to Windows in 2002 on Windows XP Media Center Edition (MCE). It was included in Home Premium and Ultimate editions of Windows Vista, as well as all editions of Windows 7 except Starter and Home Basic. It was also available on Windows 8 Pro and Windows 8.1 Pro as a paid add-on, before being discontinued in Windows 10, although it can reportedly be unofficially reinstalled using a series of Command Prompt commands. Media Center can play slideshows, videos and music from local hard drives, optical drives and network locations. Users can stream television programs and films through selected services such as Netflix. Content can be played back on computer monitors or on television sets through the use of devices called Windows Media Center Extenders. It is also possible to watch and pause live TV. Up to six TV tuners on a tuner card are supported s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Media Foundation
Media Foundation (MF) is a COM-based multimedia framework pipeline and infrastructure platform for digital media in Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10, and Windows 11. It is the intended replacement for Microsoft DirectShow, Windows Media SDK, DirectX Media Objects (DMOs) and all other so-called "legacy" multimedia APIs such as Audio Compression Manager (ACM) and Video for Windows (VfW). The existing DirectShow technology is intended to be replaced by Media Foundation step-by-step, starting with a few features. For some time there will be a co-existence of Media Foundation and DirectShow. Media Foundation will not be available for previous Windows versions, including Windows XP. The first release, present in Windows Vista, focuses on audio and video playback quality, high-definition content (i.e. HDTV), content protection and a more unified approach for digital data access control for digital rights management (DRM) and its interoperability. It in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multimedia Framework
A multimedia framework is a software framework that handles media on a computer and through a network. A good multimedia framework offers an intuitive API and a modular architecture to easily add support for new audio, video and container formats and transmission protocols. It is meant to be used by applications such as media players and audio or video editors, but can also be used to build videoconferencing applications, media converters and other multimedia tools. Data is processed among modules automatically, it is unnecessary for app to pass buffers between connected modules one by one. In contrast to function libraries, a multimedia framework provides a run time environment for the media processing. Ideally such an environment provides execution contexts for the media processing blocks separated from the application using the framework. The separation supports the independent processing of multimedia data in a timely manner. These separate contexts can be implemented as th ...

VC-1
SMPTE 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 a SMPTE standard on April 3, 2006. It was primarily marketed as a lower-complexity competitor to the H.264/MPEG-4 AVC standard. After its development, several companies other than Microsoft asserted that they held patents that applied to the technology, including Panasonic, LG Electronics and Samsung Electronics. VC-1 is supported in the now-deprecated Microsoft Silverlight, the briefly-offered HD DVD disc format, and the Blu-ray Disc format. Format VC-1 is an evolution of the conventional block-based motion-compensated hybrid video coding design also found in H.261, MPEG-1 Part 2, H.262/MPEG-2 Part 2, H.263, and MPEG-4 Part 2. It was widely characterized as an alternative to the ITU-T and MPEG video cod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Rights Management
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures (TPM) 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 (such as software and multimedia content), as well as systems that enforce these policies within devices. Laws in many countries criminalize the circumvention of DRM, communication about such circumvention, and the creation and distribution of tools used for such circumvention. Such laws are part of the United States' Digital Millennium Copyright Act (DMCA), and the European Union's Information Society Directive (the French DADVSI is an example of a member state of the European Union implementing the directive). DRM techniques include licensing agreements and encryption. The industry has expanded the usage of DRM to various hardware products, such as K ...

Windows Media DRM
Windows Media DRM or WMDRM, is a Digital Rights Management service for the Windows Media platform. It is designed to provide delivery of audio or video content over an IP network to a PC or other playback device in such a way that the distributor can control how that content is used. WMDRM includes the following components: * Windows Media Rights Manager (WMRM) SDK for packaging content and issuing licenses * Windows Media Format SDK (WMF SDK) for building Windows applications which support DRM and the Windows Media format * Windows Media DRM for Portable Devices (WMDRM-PD) for supporting offline playback on portable devices (Janus) * Windows Media DRM for Network Devices (WMDRM-ND) for streaming protected content to devices attached to a home network (Cardea) Windows Media DRM was replaced in Windows 10 Anniversary Update in favor of Microsoft PlayReady. How it works In May 2007 Microsoft published the network protocol behind its license acquisition mechanism. According to the ...

Microsoft Media Services
Microsoft Media Server (MMS), a Microsoft proprietary network-streaming protocol, serves to transfer unicast data in Windows Media Services (previously called NetShow Services). MMS can be transported via UDP or TCP. The MMS default port is UDP/TCP 1755. Microsoft deprecated MMS in favor of RTSP (TCP/UDP port 554) in 2003 with the release of the Windows Media Services 9 Series, but continued to support the MMS for some time in the interest of backward compatibility. Support for the protocol was finally dropped in Windows Media Services 2008. Microsoft still recommends using "mms://" as a "protocol rollover URL". As part of protocol rollover a Windows Media Player version 9, 10, or 11 client opening an "mms://" URL will attempt to connect first with RTSP over UDP and if that fails it will attempt RTSP over TCP. After an RTSP attempt fails, Windows Media Player versions 9 and 10 will attempt MMS over UDP, then MMS over TCP. If using Windows Media Player 11 and an RTSP attempt fa ...

Media Transfer Protocol
The Media Transfer Protocol (MTP) is an extension to the Picture Transfer Protocol (PTP) communications protocol that allows media files to be transferred automatically to and from portable devices. Whereas PTP was designed for downloading photographs from digital cameras, Media Transfer Protocol allows the transfer of music files on digital audio players and media files on portable media players, as well as personal information on personal digital assistants. MTP is a key part of WMDRM10-PD, a digital rights management (DRM) service for the Windows Media platform. In 2011, it became the standard method to transfer files to and from Android. MTP is part of the "Windows Media" framework and thus closely related to Windows Media Player. Versions of the Microsoft Windows operating system from Windows XP SP2 support MTP. Windows XP requires Windows Media Player 10 or higher; later Windows versions have built-in support. Microsoft has made an MTP Porting Kit available for older versi ...

Multicast
In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with physical layer point-to-multipoint communication. Group communication may either be application layer multicast or network-assisted multicast, where the latter makes it possible for the source to efficiently send to the group in a single transmission. Copies are automatically created in other network elements, such as routers, switches and cellular network base stations, but only to network segments that currently contain members of the group. Network assisted multicast may be implemented at the data link layer using one-to-many addressing and switching such as Ethernet multicast addressing, Asynchronous Transfer Mode (ATM), point-to-multipoint virtual circuits (P2MP) or InfiniBand multicast. Network-assisted multicast may also be impl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Media Stream Broadcast
Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially meant for streaming media. ASF is part of the Media Foundation framework. Overview and features ASF is based on serialized ''objects'' which are essentially byte sequences identified by a GUID marker. The format does not specify how (i.e. with which codec) the video or audio should be encoded; it just specifies the structure of the video/audio stream. This is similar to the function performed by the QuickTime File Format, AVI, or Ogg formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives. The most common media contained within an ASF file are Windows Media Audio (WMA) and Windows Media Video (WMV). The most common file extensions for ASF files are extension (audio-only files using Windows Media Audio, with M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DVR-MS
DVR-MS (''Microsoft Digital Video Recording'') is a proprietary video and audio file container format, developed by Microsoft used for storing TV content recorded by Windows XP Media Center Edition, Windows Vista and Windows 7. Multiple data streams (audio and video) are wrapped in an ASF container with the extension DVR-MS. Video is encoded using the MPEG-2 standard and audio using MPEG-1 Audio Layer II or Dolby Digital AC-3 (ATSC A/52). The format extends these standards by including metadata about the content and digital rights management. Files in this format are generated from the ''Stream Buffer Engine (SBE.dll)'', a DirectShow component introduced in Windows XP Service Pack 1. Playback and editing The DVR feature of Windows XP Media Center Edition, Windows Vista and the Windows 7 version of Windows Media Center create files in this format. If a recorded broadcast is marked as copy protected, the resultant DVR-MS file can only be played back on the recording device. Un ...
