Keyframe Insertion: Enabling Low-Latency Random Access and Packet Loss Repair

From a video coding perspective, there are two challenges when performing live distribution over error-prone networks, such as wireless networks: random access and packet loss repair. There is scarceness of solutions that do not impact steady-state usage users with reliable connections. The proposed solution minimizes this by complementing compression-efficient stream companion solely consisting keyframes. Although the core idea new, paper first work to provide restrictions modifications necessary make using High-Efficiency Video Coding (H.265/HEVC) compression standard. Additionally, through thorough quantification, insight provided on how low-latency fast channel switching capabilities error recovery at low quality impact, i.e., less than 0.94 average Multimethod Assessment Fusion (VMAF) score decrease. Finally, worst-case drift artifacts described visualized reader gets an overall picture keyframe insertion technique.
