Advanced Systems Format (.asf) The Advanced Systems Format (ASF) is the preferred Windows Media file format. With Windows Media Player, if the appropriate codecs are installed on your computer, you can play audio content, video content, or both, that is compressed with a wide variety of codecs and that is stored in an .asf file. Additionally, you can stream audio and video content with Windows Media Services, or you can package that content with Windows Media Rights Manager. ASF is an extensible file format that stores synchronized multimedia data. It supports data delivery over a wide variety of networks and protocols. It is also suitable for local playback. ASF supports advanced multimedia capabilities including extensible media types, component download, scalable media types, author-specified stream prioritization, multiple language support, and extensive bibliographic capabilities that include document and content management. Typically, ASF files that contain audio content that is compressed with the Windows Media Audio (WMA) codec use the .wma extension. Similarly, ASF files that contain audio content, video content, or both, that is compressed with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs use the .wmv extension. Finally, content that is compressed with any other codec use the generic .asf extension. For more information about ASF, visit the following Microsoft Web site:

MPEG-4 is an International Standards Organization (ISO) specification that covers many aspects of multimedia presentation including compression, authoring and delivery. Although video compression and file container definition are two separate and independent entities of the MPEG-4 specification, many people incorrectly believe that the two are interchangeable. You can implement only portions of the MPEG-4 specification and remain compliant with the standard. The MPEG-4 file format, as defined by the MPEG-4 specification, contains MPEG-4 encoded video and Advanced Audio Coding (AAC)-encoded audio content. It typically uses the .mp4 extension. Windows Media Player does not support the playback of the .mp4 file format. You can play back .mp4 media files in Windows Media Player when you install DirectShow-compatible MPEG-4 decoder packs. DirectShow-compatible MPEG-4 decoder packs include the Ligos LSX-MPEG Player and the EnvivioTV. For more information about the Ligos LSX-MPEG Player, visit the following Ligos Web site:

Data loss prevention is a security solution that identifies and helps prevent unsafe or inappropriate sharing, transfer, or use of sensitive data. It can help your organization monitor and protect sensitive information across on-premises systems, cloud-based locations, and endpoint devices. It also helps you achieve compliance with regulations such as the Health Insurance Portability and Accountability Act (HIPAA) and General Data Protection Regulation (GDPR). When it comes to security data, following information protection and governance best practices is critical Information protection places controls (for example, encryption) around sensitive data, while information governance determines its lifecycle (how long an organization retains the data). Together, they help your organization understand, safeguard, and govern its data.

Prevent insider breaches and fraud by managing the digital identities of employees, vendors, contractors, and partners across your network, apps, and devices. Role-based access control is one example of providing access to only the people who need it to do their jobs.

Windows uses the Wave Form Audio (WAV) file format to store sounds as waveforms. One minute of Pulse Code Modulation (PCM)-encoded sound can occupy as little as 644 kilobytes (KB) or as much as 27 megabytes (MB) of storage. This size of the storage space depends on the sampling frequency, the type of sound (mono or stereo), and the number of bits that are used for the sample. Similar to the AVI and ASF format, WAV is only a file container. Audio content that is compressed with a wide variety of codecs and that is stored in a .wav file can be played back in Windows Media Player if the appropriate codecs are installed on the computer. The most common audio codecs that are used in .wav files include Microsoft Adaptive Differential Pulse Code Modulation (MS ADPCM) and uncompressed Pulse Code Modulation (PCM).

This article lists the multimedia file types that are supported by Windows Media Player 12. (How to determine your version of Windows Media Player).Note:  Additional file formats might be supported if you install new codecs in Windows. For more information, see Codecs: frequently asked questions.

Windows Media Video (.wmv, .wm) Windows Media Video (.wmv) files are Advanced Systems Format (.asf) files that include audio, video, or both compressed with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs. By using a separate extension, you can install multiple players on your computer and associate certain players with the .wmv extension for playback of audio and video sources.

Every organization must adhere to data protection standards, laws, and regulations like HIPAA, the Sarbanes-Oxley (SOX) Act, and the Federal Information Security Management Act (FISMA).

MPEG-1 (.mpeg, .mpg, .m1v) This standard permits the coding of progressive video at a transmission rate of about 1.5 million bits per second (bps). This file format was designed specifically for use with Video-CD and CD-i media. The most common implementations of the MPEG-1 standard provides a video resolution of 352x240 at 30 frames per second (fps). When you use this standard, you receive a video that is slightly lower-quality than typical VCR videos. Files that use the .m1v extension typically are MPEG-1 elementary streams that contain only video information. Files that use .mpg or .mpeg extensions typically are MPEG-1 system streams that contain MPEG-1-encoded video and MPEG-1 Layer II (MP2)-encoded audio. However, MPEG-1 system streams do not exclusively use the .mpg and .mpeg extensions. MPEG-2 program streams also frequently use .mpg and .mpeg file extensions, but they contain MPEG-2-encoded video. Because Microsoft Windows operating systems provide only an MPEG-1 video decoder, Windows Media Player cannot play MPEG-2 program streams without an additional MPEG-2 video decoder (also known as a DVD decoder pack) installed. For more information about purchasing DVD decoder packs, visit the following Microsoft Web site:
