Video on-demand (VoD) service is very popular over the mobile Internet. With the demand and quality of video contents become increasingly high, the capacity demand on mobile networks is explosively increasing. In order to sustainably accommodate the future traffic growth, operators such as Verizon start to offload video traffic with broadcasting. However, how to improve VoD users’ quality of experience (QoE) under wireless broadcasting is still an open issue, where the major challenge is the time-varying wireless channel capacity. In this paper, we design a wireless VoD scheme with a periodic broadcasting approach. The basic idea is to fragment a video into segments, which are then delivered over different broadcasting channels periodically. We integrate network coding into our scheme so that packet redundancy can counteract the wireless unreliability. Moreover, we reveal the fundamental limits our proposed scheme can achieve in terms of two key QoE metrics: access delay and probability of continuous playout. We then show the intrinsic connections between the two QoE metrics and the choice of design parameters. The tradeoff between QoE improvement and bandwidth overhead is also presented. We implement the scheme in a testbed and demonstrate comprehensive experiment results.
