Research output: Patent

Abstract

For transmitting digital video information over a network such as the Internet, a hybrid coding scheme (FIGS. 9-18) with wavelet I frame coding and H.263 predictive coding produces a robust, low bit rate video coding scheme. A new packetization method analyzes macroblock level dependency structure (FIG. 19) and packetizes the bit stream so as to minimize dependencies between packets and thereby minimize packet loss damage.
