MPEG-3

MPEG-3 is a former standard for audio compression and video compression developed by the Moving Picture Experts Group, a working group of ISO and IEC. The development of MPEG-3 was influenced by the work of Karlheinz Brandenburg and Harald Popp at the Fraunhofer Institute. The standard was intended to provide a higher quality and lower bitrate than its predecessors, MPEG-1 and MPEG-2, which were widely used in applications such as DVD and CD. The development of MPEG-3 was also related to the work of other organizations, such as the Society of Motion Picture and Television Engineers and the European Broadcasting Union.

Introduction

MPEG-3 was designed to provide a high-quality audio and video compression standard for applications such as HDTV and DVD. The standard was intended to be used in a variety of applications, including broadcasting, streaming media, and video on demand. The development of MPEG-3 was influenced by the work of Leonard Chiariglione and Rob Koenen at the CableLabs and BBC Research & Development. The standard was also related to the work of other organizations, such as the ATSC and the DVB Project. Additionally, the development of MPEG-3 was influenced by the work of Microsoft and Apple Inc. on their respective Windows Media and QuickTime platforms.

History

The development of MPEG-3 began in the early 1990s, with the formation of the MPEG working group. The group was chaired by Leonard Chiariglione and included representatives from companies such as Sony, Philips, and Thomson. The development of MPEG-3 was influenced by the work of CCETT and NHK on their respective MUSE and Hi-Vision systems. The standard was also related to the work of other organizations, such as the ITU-R and the ETSI. Furthermore, the development of MPEG-3 was influenced by the work of IBM and Intel on their respective IBM PC and Intel Architecture platforms.

Technical Details

MPEG-3 used a combination of discrete cosine transform and quantization to compress audio and video signals. The standard also included a number of tools for error correction and concealment, such as forward error correction and error concealment. The development of MPEG-3 was influenced by the work of University of California, Berkeley and Massachusetts Institute of Technology on their respective BSD and MIT License projects. The standard was also related to the work of other organizations, such as the IETF and the W3C. Additionally, the development of MPEG-3 was influenced by the work of Adobe Systems and RealNetworks on their respective Adobe Flash and RealPlayer platforms.

Applications

MPEG-3 was intended to be used in a variety of applications, including HDTV, DVD, and streaming media. The standard was also expected to be used in broadcasting and video on demand applications. The development of MPEG-3 was influenced by the work of CNN and BBC on their respective CNN.com and BBC iPlayer platforms. The standard was also related to the work of other organizations, such as the MPAA and the RIAA. Furthermore, the development of MPEG-3 was influenced by the work of Google and Amazon on their respective YouTube and Amazon Prime Video platforms.

Comparison with Other MPEG Standards

MPEG-3 was designed to provide a higher quality and lower bitrate than its predecessors, MPEG-1 and MPEG-2. The standard was also expected to be more efficient than MPEG-4, which was developed later. The development of MPEG-3 was influenced by the work of University of Cambridge and University of Oxford on their respective Cambridge University and Oxford University projects. The standard was also related to the work of other organizations, such as the European Commission and the National Science Foundation. Additionally, the development of MPEG-3 was influenced by the work of Facebook and Twitter on their respective Facebook Live and Twitter Video platforms.

Development and Cancellation

The development of MPEG-3 was cancelled in 1995, due to the lack of interest from industry players. The standard was replaced by MPEG-2, which was widely adopted for DVD and HDTV applications. The development of MPEG-3 was influenced by the work of Apple Inc. and Microsoft on their respective Macintosh and Windows platforms. The standard was also related to the work of other organizations, such as the Consumer Technology Association and the Society of Cable Telecommunications Engineers. Furthermore, the development of MPEG-3 was influenced by the work of Netflix and Hulu on their respective Netflix streaming and Hulu streaming platforms. The cancellation of MPEG-3 was also influenced by the work of Disney and WarnerMedia on their respective Disney+ and HBO Max platforms. Category:Video compression
