ISO/IEC JTC1 is the joint technical committee set up by the International Electrotechnical Commission (IEC) and the International Organization for Standardization (ISO) to prepare international Standards in the area of information technology.
JTC1 was formed in 1987 and is a vast enterprise of 18 subcommittees grouped within 11 technical directions, with over 2200 Standards published, 100 international experts from some 66 participating or observing national bodies and many other external liaison members involved in its activities.
In 2008 the US Academy of Television Arts & Sciences awarded a prestigious Emmy Award for engineering excellence to the JVT (Joint Video Team) of experts from the IEC and ISO MPEG (Moving Picture Experts Group) which is a part of JTC1 and the ITU (International Telecommunication Union) VCEG (Video Coding Experts Group) for their work in producing the advanced video coding Standard known as ITU-T H.264 or ISO/IEC 14496-10 Advanced Video Coding (AVC).
The team developed the High Profile (HiP) that extends the reach of high-quality video in mobile telephones right through to HDTV (High Definition Television). HiP is also adopted into HD DVD and Blu-ray Disc.
ISO/IEC 14496.3 was prepared by ISO/IEC JTC 1:Information Technology, Subcommittee SC 29: Coding of Audio, Picture, Multimedia and Hypermedia Information.
The most recent version of ISO/IEC 14496.3:2009, produced by this joint committee, ISO/IECJTC1, integrates many different types of audio coding: natural sound with synthetic sound, low bitrate delivery with high-quality delivery and lossless coding, speech with music, complex soundtracks with simple ones, and traditional content with interactive and virtual-reality content. By standardising individually sophisticated coding tools – as well as a novel, flexible framework for audio synchronisation, mixing and downloaded post-production – ISO/IEC 14496.3:2009 creates adequate technology for a new, interactive world of digital audio.
ISO/IEC 14496.3:2009, unlike previous audio Standards created by ISO/IEC and other groups, does not target a single application such as real-time telephony or high-quality audio compression. Rather, it applies to every application requiring the use of advanced sound compression, synthesis, manipulation or playback. ISO/IEC 14496.3:2009 specifies state-of-the-art coding tools in several domains. As these tools are integrated with the other parts of ISO/IEC 14496, new possibilities for object-based audio coding, interactive presentation, dynamic soundtracks, and other sorts of new media are enabled.
Since a single set of tools is used to cover the needs of a broad range of applications, interoperability is a natural feature of systems that build on ISO/IEC 14496.3:2009.
