A Novel Algorithm for Decapsulation and Decoding of DVB-H Link Layer Forward Error Correction

DVB-H, which is an amendment of DVB-T, 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. Drawbacks of the decoding solution have been recognized in previous research. This paper presents a novel algorithm for decapsulation and decoding at DVB-H link layer. The algorithm is based on information provided in the transport stream packet headers and requires no changes to the DVB-H standard.
