Checksum-aided video error correction for real-time, streaming and broadcast video applications

近年来，我们目睹了视频设备、应用和系统的惊人快速部署，随着4K/8K超高清格式、用于远程监控机械、交通和医疗保健的视频设备、虚拟和增强现实以及其他由新兴物联网产生的设备等新兴技术的出现，视频的增长在未来几年只会加剧。然而，在不可靠的网络(例如，无线和卫星)上的传输错误会导致严重的视觉障碍或极大地降低网络的有效性(例如，通过引起重传)。在大多数实时和接近实时的视频应用中，此类错误会显著降低用户的体验质量(QOE)。

In the recent years, we have witnessed an impressively rapid deployment of video devices, applications and systems, and the growth of video will only intensify in the coming years with emerging technologies such as 4K/8K Ultra HD formats, video devices for remote monitoring and control of machinery, transport and healthcare, virtual and augmented reality, and other devices resulting from the emerging Internet of Things. However, transmission errors over unreliable networks (e.g. wireless and satellite) cause significant visual impairments or dramatically reduce the effectiveness of networks (e.g. by causing retransmissions). Such errors significantly degrade the user’s quality of experience (QoE) in most real-time and near real-time video applications.
