ISO/IEC 11172

ISO/IEC 11172 is a standard for audio and video compression, developed by the ISO and IEC. This standard is also known as MPEG-1, which was developed by the MPEG committee, consisting of experts from IBM, Toshiba, and Sony. The standard was designed to provide a compressed format for storing and transmitting audio and video data, and it has been widely used in various applications, including CD-ROM, DVD, and Internet streaming, with the involvement of companies like Microsoft, Apple, and Google.

Introduction

The introduction of ISO/IEC 11172 marked a significant milestone in the development of multimedia technology, enabling the efficient storage and transmission of audio and video data. This standard was developed in collaboration with various organizations, including the EBU, SMPTE, and IEEE, with contributions from experts like Leonardo Chiariglione and Hiroshi Yasuda. The standard has been widely adopted in various industries, including entertainment, education, and communication, with companies like Disney, BBC, and AT&T utilizing the technology. The development of ISO/IEC 11172 was also influenced by other standards, such as H.261 and MPEG-2, which were developed by the ITU and MPEG committee, respectively.

History

The development of ISO/IEC 11172 began in the late 1980s, with the formation of the MPEG committee, which consisted of experts from Japan, Europe, and United States. The committee was chaired by Leonardo Chiariglione, who played a key role in the development of the standard, with support from organizations like UC Berkeley and MIT. The standard was published in 1991, and it has since undergone several revisions, with the latest version being published in 1993, involving companies like Intel, Cisco Systems, and Ericsson. The development of ISO/IEC 11172 was influenced by other standards, such as H.261 and MPEG-2, which were developed by the ITU and MPEG committee, respectively, with contributions from experts like Kees Schouhamer Immink and Karlheinz Brandenburg.

Technical Overview

The ISO/IEC 11172 standard provides a compressed format for storing and transmitting audio and video data, using a combination of DCT and Huffman coding. The standard supports various audio and video formats, including MP3 and MPEG-1 Video, which were developed by companies like Fraunhofer IIS and Thomson. The standard also provides a mechanism for error correction and concealment, using techniques like FEC and error concealment, with the involvement of organizations like NIST and ETSI. The technical aspects of the standard were influenced by other technologies, such as JPEG and MPEG-2, which were developed by the JPEG committee and MPEG committee, respectively, with contributions from experts like Gerald Pearson and Didier Le Gall.

Applications

The ISO/IEC 11172 standard has been widely used in various applications, including CD-ROM, DVD, and Internet streaming, with companies like Microsoft, Apple, and Google utilizing the technology. The standard has also been used in various industries, including entertainment, education, and communication, with organizations like BBC, Disney, and AT&T adopting the technology. The standard has been used in various devices, including PCs, STBs, and mobile devices, with the involvement of companies like Samsung, LG, and Sony. The applications of the standard have been influenced by other technologies, such as H.264 and VC-1, which were developed by the ITU and SMPTE, respectively, with contributions from experts like Gary Sullivan and Ajay Luthra.

Standard Specifications
