UCSD inventors have come up with a means for (1) perceptual video coding, (2) R-D optimization, (3) sub-pixel motion estimation within the H.264 video codec. This method reduced memory used (16 times less) and achieved better encoding times (50% faster).  Using this invention it is possible to transmit real-time video over low-bit rate channels. 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 memory usage using innovative techniques both for the motion estimation process and for the image coding.
