Abstract
The disclosure generally relates to methods and systems for maintaining quality of experience (QoE) in real-time live video streaming. Conventional techniques in achieving the QoE employ either additional bandwidth of the network or compromise on a latency of the network. The present disclosure provides a rendering algorithm to compensate for lost entropy without attempting to regain exact lost packet(s) information. The rendering algorithm enhance the QoE by regaining structural continuity of the lost packet(s) information despite variations in the end-to-end transmission channel. A segmentation algorithm is employed to segment each frame into one or more packets, so that each packet should only have integer number of MCU blocks. The rendering algorithm to identify the lost packets and to compensate the lost information. The present disclosure provides a loss resilient solution to maintain the QoE without trading off the bandwidth efficiency and the network latency.
