DVB-H offers reliable high data rate reception for mobile handheld and battery-powered devices. A link layer with error correction is defined to work on top of the DVB-T physical layer. The DVB-H standard suggests to use Reed-Solomon coding combined with cyclic redundancy check error detection as the link layer forward error correction. However, there exist more powerful methods for decoding. In this paper, a detailed comparison of five different decoding strategies is presented of which all are compatible with the current standard. Comparison is based on frame error, IP packet error and byte error rates after decoding. Also, the effect of errors on visual experience of a video stream is analyzed
