A bandwidth limited and error tolerant nVoD schema for satellite networks
In this paper, we present a bandwidth limited and error tolerant near-Video-on-Demand (nVoD) schema suitable for satellite networks. Compared to traditional nVoD schemas, such as carousels, it outperforms in terms of download start letency and packet loss tolerance. Video-on Demand (VoD) has been a topic of intense research in the past. The main problem of VoD systems is that their bandwidth requirements do not scale well with user requests. For this reason, VoD is only feasible under some constraints. In general, nVoD systems are an approximation of VoD ones. In them, downloads do not necessarily start when the request arrives, but some time later. by doing so, it is possible to bound the total required bandwidth at the cost of introducing some delay in content download.
