Abstract

Mobile reception of digital TV often suffers from severe signal degradations. Inter-sequence error concealment reconstructs lost image blocks of a distorted high-resolution TV signal by inserting corresponding error-free blocks from a low-resolution reference TV signal. It is well-suited for application in future automotive multi-broadcast receivers and can outperform state-of-the-art methods by up to 15 dB PSNR depending on the quality of the reference signal. In this contribution, we show that inter-sequence error concealment can be improved by approximating inserted blocks jointly with neighboring pixels according to a well-known frequency selective method. The reconstruction quality can be significantly increased especially in case of low-bitrate reference signals. Inserted blocks can be further refined also for high bitrates. On average, a gain of 1.7 dB PSNR can be achieved. The peak gain which is evaluated on frame basis even reaches 5.6 dB PSNR. © 2010 ACM.
