摘要

This paper proposes an approach to change ordinary IMT-2000 mobile phone to videophone with less effort by using a newly developed chip/IP (Intellectual Property) core set. The chip/IP core set is composed of speech codec DSP, video codec LSI and multiplexing/demultiplexing IP. Furthermore,,an integrated next generation LSI for videophone is also introduced. The developed chip/IP core set is designed to realize upcoming a new 3GPP standard, based on popular ITU-T standard H.324 but some modifications are included for efficient implementation in IMT-2000 wireless network.
