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

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.
