Robust Coding and Packetization of Images and Intraframe-coded Video

In this text we consider the problem of robust image/video coding and packetization for the purpose of communication over a packet network. The focus is on Internet transmission. A novel method for achieving error resilience in subband-coded image/video communication is presented. Its characteristic is that subband coe¢cients stored in the same packet are dispersed across the space-frequency domain which enables easy error concealment. Proposed packetization algorithm produces equally important packets, shown to be optimal for minimizing the variation in received image/video quality. The proposed method performs well compared to the other similar state-of-the-art packetization method and is shown to achieve up to 1dB improvement in PSNR at high packet loss rates.
