A newly derived algorithm called three-dimensional polynomial approximation coding (3DPAC) is being utilized in the applications of wireless video transmission. After combining the spatial and temporal domain, the video data is organized in a cube form, which has the features of processing parallelism and great compression ratio. Such a very low bit-rate video codec is able 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 demonstration is also shown. For a video sequence of 176 × 144 frame size, PSNR up to 35 dB maybe obtained under 6.5 kbits/s transmission rate.
