Error resilience schemes for digital terrestrial TV broadcasting system

Abstract

An error-resilient scheme incorporated with the MPEG-2 standard is developed to support robust video transmission in digital terrestrial TV broadcasting (DTTB) systems. In particular, a novel concealment algorithm based on temporal error concealment and block-matching methodology is proposed. This algorithm achieves an effective concealment while keeping low computational complexity with small size of search-window for block-matching. Likewise, an effective reception for isolate I-pictures is developed. Moreover, combining with an efficient detection of spatial/temporal activity, an adaptive error concealment scheme is further contrived. Extensive simulations have confirmed that the proposed error-resilient schemes may achieve efficient and robust video transmission in a DTTB system even with a very high packet error rate.
