摘要

In this paper a new technique for error concealment of digital TV signals in a diversity reception scenario is proposed. Inter-sequence error concealment utilizes one or more reference sequences to reconstruct lost image blocks or slices of a video sequence. Based on the general approach of image combination for uncompressed video sequences, inter-sequence error concealment of coded TV sequences is evaluated in detail. The presented technique especially considers error propagation by motion-compensated prediction in hybrid video coding. The algorithm for error concealment is introduced on example of DVB-T signals which are transmitted in multi-frequency networks. In practice, applications like multi-standard-reception of DVB-T, DVB-H and T-DMB seem also natural.
