INVESTIGATION OF A VISUAL TELEPHONE PROTOTYPING ON PERSONAL COMPUTERS
A personal computer (PC) based platform for visual telephone prototyping is introduced in this paper. ITU-T H.324 standard is the basis of the whole system. Video compression algorithms are implemented to achieve satisfactory visual quality for bit-rate less than 28.8 Kbps. Window menu interactive environment and modem communication interface are developed. Simulation results reveal the potential of the PC based solution.
