Abstract

In this paper, based on the analysis of the existing encapsulation schemes, Generic Stream Encapsulation (GSE) is chosen to transmit IP-based services in the Terrestrial - Digital Multimedia Broadcasting (T-DMB) system. As a new emerging technology, no corresponding Forward Error Correction (FEC) function is considered for GSE. This motivates us to propose a GSE-FEC method for obtaining additional error protection, in the form of Reed Solomon (RS) outer error protection and virtual interleaving. To further improve the error correction capability of the proposed GSE-FEC, an Improved GSE Erasure (IGE) decoding scheme is presented. This IGE scheme allows us to obtain the erasure information and GSE-FEC frame reconstruction information by an Improved GSE (IGSE encapsulation scheme. Simulation results demonstrate that the IGE scheme shows better characteristics than the Non-Erasure (NE) decoding scheme and the GSE Erasure (GE) decoding scheme which is based on the original GSE encapsulation. Moreover, compared with the GE scheme, the proposed scheme can reserve the correct bytes to the best of its ability for avoiding information wasting. © 2008 IEEE.
