In this paper, we propose a novel wireless video transmission scheme named HDA-Cast, which is a hybrid digital-analog (HDA) coding scheme that integrates the advantages of digital coding and analog coding. Relative to most state-of-the-art video transmission methods, it avoids the “cliff effect” provided that the channel quality is within the expected range, gives better fairness among all receivers for multicast, and has strong adaption to channel variation. The evaluation results show that our HDA-Cast is 3.5-9.6 dB better than the SoftCast which is an up-to-date analog scheme. Owing to its strong adaption to channel variation, it can be regarded as a kind of wireless scalable video coding (WSVC).
