- Abstract
- Compressed video is more fragile to transmission errors due to its highly organized structure. Consequently the quality of pictures is degradated. Error Concealment (EC) makes use of the redundancies that still remain in frequency, temporal or spatial domain with the compressed video bit stream. In this paper three Error Concealment (EC) algorithms: Previous Coded Block Linear Error Concealment (PCB-EC), Four Neighbors Linear Error Concealment (4N-EC) and Eight Neighbors Linear Error Concealment (8N-EC) were implemented and tested. We found that the proposed 4N-EC algorithm can achieve PSNR increments of 8.2dB after recovery while other algorithms can only improve 1-2dB after recovery.
