Özet

In this work, we propose a low bit rate video transmission scheme in a Rayleigh fading channel. Source coding in this scheme is accomplished by subband coding. To overcome the bad effects of the channel we use Reed Solomon codes together with direct sequence spread spectrum. While compressing the video signal, different image resolutions are achieved by subband coding. These images have different priority levels against channel distortion according to their information content. Consequently reasonable image quality is obtained even in adverse channel conditions.
