UC San Diego inventors have come up with a low-complexity video compression engine, suitable for next generation interactive mobile phones. Using this invention, it is possible to transmit video sequences for video conferencing on a wireless channel. One of the most interesting features offered by this engine is the possibility to work both with the current mobile network infrastructure (9.6 kbps) as well as with the third generation (3G). This invention addresses the issues with current video compression technologies that, while they provide remarkable performance in terms of image quality, were designed without considering the severe constraints imposed by mobile devices. The proposed encoding scheme achieves good visual quality and high compression ratios with a reduced computational complexity using innovative techniques for the motion estimation process and the image coding.
