Video coding: the next generation

The International Telecommunication Committee has recently launched a project that will develop standards to enhance the performance of video coding.

The International Telecommunication Committee (ITU), along with the International Organization of Standardization (ISO) / International Electrotechnical Commission (IEC), recently launched a project to develop new standards to enhance the performance of video coding.

The standards, known as ISO/IEC 14496-10 ‘Advanced Video Coding,’ are being developed by the Joint Video Team (JVT) and are expected to bring substantial improvements to video coding efficiency, resulting in improved video quality at lower costs. ANSI is the US member body to ISO and, through the US National Committee, the IEC.

According to JVT chairman, Gary Sullivan, the project, which was previously known as H.26L (Improved Video Coding for Multimedia Communication), will create a single interoperable solution for a next generation of standard video coding. The purpose of the project is to improve video coding so that it will increase ‘compression efficiency,’ reducing the number of bits per second needed to store or transmit video content of common digital video applications.

Formal approval of the new standards is projected for the end of 2002.

The L3.1 US Technical Committee, which is a group of vendors and IT-user experts that develop standards for ‘Coding of Audio, Picture, Multimedia, and Hypermedia Information,’ contributed key technical input from the US perspective to JVT’s initiative. The group works under the rules and processes of the InterNational Committee for Information Technology Standards (INCITS), an ANSI member and ANSI-accredited standards developer. In conjunction with JVT, members of the L3.1 committee and INCITS have already begun developing the new video standards, which include enhancing the existing documents for digital TV signals and Internet video.

Sullivan added, ‘We’ve brought together the world’s experts to focus on creating one design together and will present that design to the industry as the appropriate standard solution for a variety of applications.’
