standard for delivering streaming multimedia content to wireless devices. An example of the technology in action might be the ability to watch movie trailers on your wireless phone.
is a much more ambitious standard and addresses speech and video synthesis, fractal geometry, computer visualization, and an artificial intelligence (AI) approach to reconstructing images. MPEG-4 addresses a standard way for authors to create and define the media objects in a multimedia presentation, how these can be synchronized and related to each other in transmission, and how users are to be able to interact with the media objects.
ISO Moving Pictures Expert Group standard originally intended for low bandwidth applications, but now offering SD and HD video, 2D and 3D graphics and animation, interactivity and scripting.
a "codec container" built around free and proprietary codecs, MPEG-4 excels at multi-architecture compatibility and efficient compression for low bandwidth streaming. Being a cross-platform container, its existance makes reduntant other platform specific container protocols: as of QuickTime, Real and WindowsMedia. The best audio/video codec tuples for MPEG4 are MP3/H.263 (widely supported on most players) and AAC/H.264 (highest efficiency).
An ISO standard based on the QuickTime file format that defines multimedia file and compression formats.
MPEG4 has a newer codec and supports 3D content, low bit rate encoding, and support for Digital Rights Management, which controls the use of copyrighted digital work. MPEG4 is used for web streaming media, broadcast television, videophones, and CD distribution. MPEG-4 is widely used in video surveillance, and has recently been improved to the AVC standard.
An ISO/IEC standard developed by the Motion Picture Experts Group for digital multimedia representation, compression, decompression, rights management, and transmission over the Internet.
An ISO/IEC standard 14496 developed by the Moving Picture Experts Group (MPEG), the committee that also developed MPEG-1 and MPEG-2. These standards made interactive video on CD-ROM, DVD and Digital Television possible. MPEG-4 is the result of another international effort involving hundreds of researchers and engineers from all over the world. MPEG-4 was finalized in October 1998 and became an International Standard in 1999. The fully backward compatible extensions under the title of MPEG-4 Version 2 were frozen at the end of 1999, to acquire the formal International Standard Status early in 2000. Several extensions were added since and work on some specific work-items is still in progress.
MPEG-4 is a group of audio and video coding standards and related technology. The primary uses for the MPEG-4 standard are web (streaming media) and CD distribution, conversational (videophone), and broadcast television. Most of the features included in MPEG-4 are left to individual developers to decide whether to implement them or not. This means that there are probably no complete implementations of the entire MPEG-4 set of standards. To deal with this, the standard includes the concept of "profiles" and "levels", allowing a specific set of capabilities to be defined in a manner appropriate for a subset of applications.
MPEG-4 is a standard defined by the Working Group 11 (Moving Picture Expert Group) of ISO (International Standard Organization) in October 1998 (date of the first draft of the standard). It is the standard for the mature digital era. With its added features, MPEG-4 offers better compression, interactivity, and universal Internet/wireless access to the medium.
The latest technology available for delivering digital video. It allows us to provide the most HD content by utilizing our existing satellites and bandwidth. DISH Network's newest MPEG technology.
A data compression format that is used for streaming video as well as small video files that can be posted to the Internet or sent via e-mail. The video resolution will be small (typically 320 x 240 pixels).
MPEG-4 is the next-generation MPEG that goes far beyond compression methods. Instead of treating the data as continuous streams, MPEG-4 deals with audio/video objects (AVOs) that can be manipulated independently, allowing for interaction with the coded data and providing considerably more flexibility in editing. MPEG-4 supports a wide range of audio and video modes and transmission speeds. It also deals with intellectual property and protection issues.
A standard defined by the MPEG group for streaming.
An international video format used by Windows Media and other systems for web video that produces good image quality at low bandwidths. MPEG-4 is fairly CPU intensive, so larger frame sizes and frame rates may require fast computers.
Released in 1999 as a video compression standard for low bandwidth devices. MPEG-4 supports data rates as low as 5Kbps and frame sizes down to 144 x 176. It is the first MPEG video compression standard to address the Internet delivery of video and is being adopted for the delivery of video to wireless devices such as 3G mobile phones.
A type of digital sound or video file.
This is a standard which is currently being defined by the MPEG committee. It is aimed at low bit-rate storage that will be useful for animated video sequences, other computer-generated imagery and games, whilst also having some compatibility with H.263. There are likely to be many modes of operation for this standard. Whilst some modes will operate similar to the ITU standards, other modes will use Video Objects that may have their textures transmitted separately.
an emerging standard for video compression which is seen as a competitor to Microsoft and RealNetworks media compression technologies.
A recent data compression format that can get better quality out of a given amount of bandwidth. MPEG-4 can compress a feature film onto a CD-ROM disc with VHS quality.
MPEG-4 is an ISO/IEC standard developed by MPEG. MPEG-4, whose formal ISO/IEC designation is ISO/IEC 14496, was finalized in October 1998, and became an International Standard in the first months of 1999. MPEG-4 builds on the proven success of three fields: Digital television Interactive graphics applications (synthetic content) Interactive multimedia (World Wide Web, distribution of and access to content) More information about MPEG-4 can be found at http://www.m4if.org.
MPEG-4 (MP4) was defined using the standards for encoding video in a digital compressed format as specified by the Moving Picture Experts Group (MPEG). It supports video, audio, and system components that are compliant with the International Organization for Standardization (ISO) MPEG-4 defacto standards. The MPEG-4 open standards are a set of specifications that are used to build products for production, encoding and delivery of audio/video content over many kinds of networks to a variety of clients such as personal computers, wireless devices, Web browsers, and many more. Device manufacturers prefer using MPEG-4 because the open architecture and codec do not lock them into specific formats or players. Instead of having to develop for three or four separate formats, which is logistically difficult and costly, providers can build on MPEG-4's single format.
The compression system developed for interactive video used for internet / video conferencing; object oriented.
A compressed video/audio encoding standard. Short for Motion Picture Experts Group Audio Layer 4.
a.k.a. MP4 Moving Picture Experts Group-4. A standard for compressing video into a compact file without losing a significant amount of its quality. Used for the transmission and storage of images and video clips.
Similar to MPEG-2, but with a much greater ability to scale to different compression rates and resolutions. MPEG-4 is suitable for applications ranging from low bit-rate streaming video applications for videoconferencing and cell phone video delivery, to high bit-rate high definition television production systems.
MPEG-4 is a graphics and video compression algorithm standard that is based on MPEG-1, MPEG-2 and Apple QuickTime technology. Wavelet-based MPEG-4 files are smaller than JPEG or QuickTime files, so they are designed to transmit video and images over a narrower bandwidth and can mix video with text, graphics and 2-D and 3-D animation layers. MPEG-4 was standardized in October 1998 in the ISO/IEC document 14496.
ISO 14496 is an ISO/IEC standard developed by MPEG (Moving Picture Experts Group). Although defined as one standard, MPEG-4 is actually a set of compression/decompression formats and streaming technologies that address the need for distributing rich interactive media over narrow and broadband networks
A variant of the MPEG video and audio compression algorithm and file format used for low bandwidth video telephony. The file extension is .MP4. The International Standards Organization (ISO) has adopted the QuickTime 3 file format to form the starting point for a unified digital media storage format for the MPEG-4 specification. See also QuickTime 3 for more information.
Expands MPEG-1 to support video/audio "objects", 3D content, low bitrate encoding and support for Digital Rights Management.
"MPEG-4" is a lossy graphics and video compression standard based on MPEG-1, MPEG-2 and Apple QuickTime technology. It was standardized in October 1998 in the ISO/IEC document â€œ14496â€. MPEG-4 widens up the earlier MPEG-1 and MPEG-2 technologies using techniques like synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing. MPEG-4 files are generally smaller than JPEG or QuickTime files. This enables the technique to be used for transmitting video and images over narrow bandwidths.
MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualization and artificial intelligence-based image processing techniques.
n. A standard currently under development designed for videophones and multimedia applications. MPEG-4 provides a lower bandwidth of up to 64 Kb/s. See also MPEG (definition 1). Compare MPEG-1, MPEG-2, MPEG-3.
MPEG-4 defines how multimedia streams â€“ video, audio, text, data â€“ are transmitted as individual objects. MPEG-4 is a compression/decompression technology that aims to achieve interactivity, efficiency and stability in narrow-band transmissions. On a broader level, MPEG-4 aims to pave the way toward a uniform, high quality encoding and decoding standard, that would replace the many proprietary streaming technologies in use on the Internet today. MPEG-4 is also designed for low bit-rate communications devices, such as mobile receivers or wristwatches that can display video. These devices are usually wireless and can have different access speeds depending on the type of connection and traffic. To overcome this problem, MPEG-4 supports scalable content. Content is encoded once and automatically played back and transmitted at different rates, depending on the available network connection.
An encoding standard that combines digital television, interactive graphics and interactive multimedia content, creating interactive videos on CD-ROM/DVD and digital television.
MPEG-4 is a standard used primarily to compress audio and visual (AV) digital data. Introduced in late 1998, it is the designation for a group of audio and video coding standards and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) under the formal standard ISO/IEC 14496. The uses for the MPEG-4 standard are web (streaming media) and CD distribution, conversation (videophone), and broadcast television, all of which benefit from compressing the AV stream.
