Recently, Tian et al. <xref ref-type="bibr" rid="ref1">[1]</xref> considered joint source-channel coding of transmitting a Gaussian source over $K$ -user Gaussian broadcast channel, and derived an outer bound on the admissible distortion region. In <xref ref-type="bibr" rid="ref1">[1]</xref>, they stated “due to its nonlinear form, it...
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...
To fairly allocate network bandwidth for different streams and to achieve a smooth quality between different video sequences are two key issues in multi-stream applications. In this paper, a new joint rate control scheme for multiple video streams based on game theory is proposed. We achieve a fair rate allocation in video quality between different sequences by Nash Bargaining theory under the constraints...
