Abstract

Mobile reception of digital TV often suffers from lost blocks and slices due to suboptimal channels. Inter-sequence error concealment reconstructs lost image blocks of distorted high-resolution TV signals by inserting corresponding error-free blocks of low-resolution reference signals. It is well-suited for automotive multi-broadcast receivers and can outperform state-of-the-art methods by up to 15 dB PSNRY. In this contribution, a novel spectral completion scheme is proposed which robustly estimates missing spatial frequencies of reconstructed blocks by extrapolation of difference images. Simulation results show that the proposed scheme can increase the reconstruction quality of inter-sequence error concealment by up to 3.2 dB. Also, the subjective quality is enhanced by significantly reducing blurring artifacts. © 2011 IEEE.
