A newly derived algorithm called three-dimensional polynomial approximation
coding (3DPAC) is being utilized in the applications of wireless video tra
nsmission. After combining the spatial and temporal domain, the video data
is organized in a cube form, which has the features of processing paralleli
sm and great compression ratio. Such a very low bit-rate video codec is abl
e to support the wireless data transmission with a bit rate lower than 9.6
kbits/s, The system architecture will be presented and an experimental demo
nstration is also shown. For a video sequence of 176 x 144 frame size, PSNR
up to 35 dB maybe obtained under 6.5 kbits/s transmission rate.
