Abstract

Most real-time video applications typically demand low end-to-end latency and faithful reconstruction of the video sequence. Many popular video coding standards (e.g. VP8, VP9, H.264 and HEVC) aim at achieving high compression efficiencies by exploiting spatial and temporal redundancies. This makes the encoded bitstream vulnerable to errors. Thus, applications especially on mobile phones, tablet PCs and other portable devices that use WiFi or 3G/4G/LTE networks typically suffer from low quality of service typically characterized by frequent delays, jitter, frozen picture, partial/no picture and total loss of connection. Similar scenarios are also often observed while watching live streaming accompanied by service interruptions and a blank screen. Our approach is to investigate error resilient coding control for the VPx encoder to make the bitstream more error resilient for streaming applications under lossy channel conditions. In this paper, we describe an error resilient coding system that uses duplication of frame prediction information. Our “error resilience packet” consists of this prediction information of several frames, that can be used for error concealment in the case of packet loss.
