Impact of Intra-Refresh on Error Resilience and Compression Efficiency in MV-HEVC

The latest multi-view video coding standard, MV-HEVC, efficiently represents multi-view video sequences, reducing the required network bitrate, and incorporates error resilience tools to maintain video quality even under adverse network conditions. This paper investigates the impact of random error propagation in the MV-HEVC Network Abstraction Layer (NAL) and presents a comprehensive analysis of MV-HEVC bitstream sensitivity under error-prone networks. The study identifies the most sensitive data within the MV-HEVC bitstream and proposes an intra-refresh transcoding scheme to enhance the robustness of the MV-HEVC bitstream transmission. Experimental results ensured better video quality under adverse network conditions with an improvement of 22 dB in the perceptual quality of received multi-view video with minimal performance overhead.
