A new chip/IP core set for 3G-324M video telephony

This paper proposes an approach to change an ordinary IMT-2000 mobile phone to a videophone with less effort by using a newly developed chip/IP (intellectual property) core set. The chip/IP core set is composed of a speech codec DSP, a 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 the upcoming new 3GPP standard, based on the popular ITU-T standard H.324 but some modifications are included for efficient implementation in the IMT-2000 wireless network.
