In digital video broadcasting-handhelds (DVB-H), the contents to be transmitted come in the form of internet protocol (IP) datagram, which are passed to the multi- protocol encapsulation with forward error correction (MPE-FEC) entity. MPE-FEC employs erasure Reed-Solomon (eRS) error correction combined with cyclic redundancy check (CRC), is defined in standard. However, a critical factor must be considered when dealing with a long-term fading channel. If there is only one bit error in an IP packet, the entire IP packet is considered unreliable, even if it contains many correct bytes. To mitigate this effect, this paper proposed hybrid decoding algorithm using the log likelihood ratio (LLR) values. By simulation we show that the performance of the proposed decoding algorithm is superior to that of conventional one.
