A Novel General End-to-End Distortion Estimation Model for Video Transmission[J]. Journal of Image and Graphics, 2006, 11(6): 792. DOI: 10.11834/jig.200606133.
The end-to-end error propagation distortion on pixel level precision is analyzed based on temporal concealment strategies in decoder and channel error rate. By using frame correlative coefficient and concealment ratio of TR and MCR
a new general transmission distortion estimation model for various temporal concealments is proposed. The estimation accuracy is demonstrated via simulation results for video transmission over packet loss channel
which illustrates that actual distortion can be estimated by proposed expectation model approximately. The proposed model provides an efficient method for MB coding parameters optimal selection over error prone environment. The simulation results also show that the MB mode INTRA-update algorithm based on proposed model has better substantial and consistent gains than traditional R-D optimal INTRA-update algorithm.
