Alcatel-Lucent shows improved DVB-SH
IFA 2008 - BERLIN. Alcatel-Lucent is demonstrating, for the first time in Europe, MPE-iFEC (Multi-Protocol Encapsulation - inter-burst Forward Error Correction), an error-correction coding that improves the quality of broadcast mobile TV reception in hybrid satellite and terrestrial networks. The feature is embedded in the DVB-SH mobile broadcast standard.
In a satellite DVB-SH reception context, MPE-iFEC is an extension of the traditional MPE-FEC (Multi-Protocol Encapsulation Forward Error Correction) error correction system used in terrestrial systems. The MPE-FEC extension, through inter-burst FEC, compensates long shadowing by providing additional time diversity. MPE-iFEC is an attractive alternative to the long physical interleaver standard option for those small receivers which cannot afford a large and fast de-interleaving memory.
Furthermore, applied to a terrestrial DVB-SH reception context, the MPE-iFEC feature significantly enhances the error-correction performances, improving the video image quality of broadcast mobile TV for the end-users.
The demonstration at IFA 2008 is using DVB-SH ready “SAGEM myMobileTV” handsets from Sagem Mobiles, empowered by DiBcom’s DVB-SH ready receivers, receiving a selection of pre-recorded contents in the 2.2GHz (S-Band) frequency spectrum.
The S-Band frequency spectrum is currently available throughout Europe. On August 7, 2008, the European Commission opened a competition for providers of communication services via satellite across Europe. Using the S-Band, satellite operators will, for the first time, be able to offer services such as high speed data, mobile TV, disaster relief and remote medical services under a single European selection procedure instead of under 27 different national systems. This is made possible by a new EU decision on mobile satellite services that entered into force in July 2008.
