Abstract

The challenge of narrow-band video transmission is to produce smooth motion and acceptable image quality. Advances in commercial video teleconferencing have produced products capable of transmitting audio, video, and control information over wired communication channels at increasingly lower bit rates. Wireless narrow-band communication channels require a portion of their bandwidth to be reserved for error resilient coding further reducing the amount of available bandwidth for video. This paper presents the results of wavelet based pre- and post- processing algorithms wrapped around an industry standard video coder/decoder. This WaveNet Wrapper provides an increase in frame rate and codec efficiency for a given bit rate.
