A zero-overhead implicit error correction nVoD schema for scalable video

In a previous paper we presented a new near Video on Demand schema with error correcting capabilities, without any bandwidth overhead. In this paper, we extend this schema to support scalable video. The clients can adapt the video to quality they can support. Moreover, they can reduce quality in case of unrecovered errors, as far as the lowest quality layer is available, guaranteeing continuous playback.
