Abstract

This paper presents some improved algorithms of video and audio codecs for multimedia communication terminals based on an Intel Pentium PC under the Win9x OS. They are optimized using the characteristics of an Intel Pentium processor, and simplified depending on human perception. They have been used in ITU-T H.263 and G.723.1 to a completed H.323 using an Intel Pentium II 350 MHz processor as a hardware platform. This H.323 terminal can code and decode an audio signal in real time together with coding and decoding a video signal of about 15 frame/s with the CIF format.
