摘要: In this paper we study the perceptual impact of data loss on MPEG-2 video coded streams transmitted over an ATM network. This is measured using a quality metric based spatio-temporal model human visual system. Video have been top both new network and adaptation layers which provide robust transmission by applying per-cell sequence numbering combined with selective Forward Error Correction (FEC) mechanism. We compare their performance against AAL5. Results show that proposed AAL behaves better in terms perceived decoded
