Abstract

An unequal error protection approach for the reliable communication of visual information over additive white Gaussian noise channels is proposed and studied. This method relies on a bandwidth-efficient coded modulation scheme that employs selective channel coding and transmission energy allocation in conjunction with sequence maximum a posteriori soft-decision detection. Experimental results indicate that this scheme exhibits graceful performance degradation as the channel conditions deteriorate and provides substantial objective and subjective improvements over uncoded and equal-error protection systems. Coding gains of up to 4 dB in Eb/No are achieved. Index Terms- Image/video communication, MAP detection, transmission energy allocation, trellis-coded modulation, unequal error protection.
