Abstract

An effective MPEG-2 spatial scalable video codec is designed, and error concealment technique of associated transport stream is proposed. The spatial scalability can provide robust error resilience for Ka-band rain attenuation, as well as the co-existence of HDTV and SDTV systems. In MPEG-2, the spatial scalable encoder combines both spatial and temporal predictions. This paper proposes a near optimal spatial-temporal weighting analyzer to properly assign weights. Simulation shows that the proposed spatial scalable codec structure outperforms the performance of the other MPEG-2 codecs for TV broadcasting in Ka-band using satellites. We also propose a suitable error protection and concealment method for MPEG-2 transport stream. With the combination of scalable coding and error protection systems, the proposed system will achieve high link availability
