AVS standard to eventually replace MPEG-4

Image recognition will become a very important technology. All of its typical applications, such as face recognition, iris recognition, text recognition, have huge market potentials.

Currently, still images mainly use JPEG code compression technology. In the future, the next-generation JPEG2000 code compression technology will be used. JPEG2000 has a compression ratio that is 10 to 30 percent higher than that of JPEG which was created mainly to meet the need for low bandwidth high noise environments, as well as medical imaging, digital library, faxing, and Internet service, among others.

Dynamic images now mainly use MPEG-2 and MPEG-4 technologies. MPEG-4 is a second-generation coding technology with a higher compression ratio that has better multimedia interaction and stronger code fault tolerance capabilities. As a result, this will have broader applications in the next few years in areas such as VoD, Internet A/V transmission, HDTV, and 2.5G and above handset platforms. For instance, MPEG-4 will enable handsets of 2.5G and above to receive dynamic digital TV programs and carry out videoconferences involving multiple remote participants.

In order to take an advantageous position in future multimedia transmission and communication applications such as HDTV, DVD, Internet/wireless network-based A/V service, China is also striving to develop the AVS - a dynamic image code compression standard that has the potential to replace MPEG-2/4.

Vimicro has already released processors for clip-on cameras in cellphones. In the near future, Vimicro will also release two series of highly integrated chips targeting cellphone A/V. Eventually Vimicro will release an SoC device to further enchance the multimedia applications in cellphones. This SoC is expected to become a core component of future 3G wireless handheld devices.
