摘要

在本文中，我们介绍了一种针对高错误率移动网络中基于注视点的错误恢复的不平等错误保护技术。对于点对点的视觉通信，采用基于注视点的误差恢复能力，根据人眼的注视方向将每帧图像分为注视点层和背景层，并生成两个比特流，可以显著提高视觉质量。为了提高中心层的源吞吐量，我们在H.223附录c中采用不等延迟约束的ARQ和RCPC(速率兼容的针孔卷积)编码。在仿真中，在信道信噪比为5 dB至15 dB的情况下，视觉质量在0.3 dB至1 dB范围内提高。

Unequal error protection for foveation-based error resilience over mobile networks

In this paper, we introduce an unequal error protection technique for foveation-based error resilience over highly error-prone mobile networks. For point-to-point visual communications, visual quality can be significantly increased by using foveation-based error resilience where each frame is divided into foveated and background layers according to the gaze direction of the human eye, and two bitstreams are generated. In an effort to increase the source throughput of the foveated layer, we employ unequal delay-constrained ARQ and RCPC (rate compatible punctured convolutional) codes in H.223 Annex C. In the simulation, the visual quality is increased in the range of 0.3 dB to 1 dB over channel SNR 5 dB to 15 dB.
