A user bitrate preference-aware streaming algorithm based on network coding

The difference among the heterogeneous user bitrate preference has greatly limited the quality-of-experience (QoE) due to the heterogeneous network environment and devices, and the homogeneous download schedule in wireless video streaming. Multi-resolution code network coding has emerged as a promising approach to delivering videos in multiple description coding (MDC) streaming, where chunks of different layers are delivered to users. In this paper, a bitrate-aware streaming algorithm was proposed based on network coding to satisfy users bitrate preference, considering the network condition, user interests, and content property that together characterize the user preference. Experimental results show that the proposal algorithm outperforms traditional approach in user preference satisfaction and higher network utilization, such that users can enjoy both improved bitrate and streaming continuity.
