Next-Generation Network Code
The way that audio and video elements are translated or coded is key to multimedia delivery. And development of coding recommendations by ITU has continued in 2001 with a major announcement on a new team to deliver the next-generation video coding standard.
The Joint Video Team (JVT) is another example of ITU-T’s commitment to working with other standards developing organizations (SDOs). ITU-T and ISO/IEC have partnered for a project that will enhance standard video coding performance. This new working party, the Joint Video Team (JVT), is expected to bring substantial improvements in video coding efficiency, which will result in improved video quality. The new standard is anticipated to be of use in all areas where bandwidth or storage capacity is limited.
The JVT project will take over the
ITU-T H.26L (Improved Video Coding for Multimedia Communication) project of ITU-T and create a single interoperable solution for a next generation of standard video coding. It will result in technically aligned standards in MPEG. Formal approval of the new standards is expected to be complete by the end of 2002.
In addition, 2001 has seen the approval of a new speech codec that gives significant improvement to speech quality. The new standard — ITU-T
G.722.2 — is expected to be used in applications such as Voice over IP (VoIP), high-quality
audio and videoconferencing and ISDN wideband telephony. The codec has been selected by 3GPP (Third Generation Partnership Project) as the Wideband codec for GSM and 3G wireless applications.
