简介
This paper proposes a layered video transmission scheme to extend the coverage area for DSL video delivery. The proposed architecture is based on a joint source-channel coding approach, and combines layered video transcoding with unequal error protection using hierarchical multi-carrier transmission. Based on a new image quality metric, the developed method automatically determines the optimal system parameters in terms of end-user perceived quality. Simulation results show that the proposed quality-oriented video delivery architecture extends the coverage area for DSL video distribution significantly for the end user, while providing more robust video services.
