Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes methods of the parallerised LDGM(low density generator matrix) coding for the streaming of super high definition videos(SHD). LDGM is a kind of forward error correction codes(FEC), which has a better performance both about the charactoristics of error corrections and about the rate of encoding/decoding proccess.
Firstly in this paper, we evaluate the static performance of LDGM code such as the packet loss rate rate vs packet error rate. After that, we decide the best paramaters of the LDGM code for the SHD streamings, according to the evaluation. Finaly, we measure the throughput of LDGM encodings with the proposed methods.
