Abstract

As intelligent content management of IPTV moves popular material nearer to the end-user, application-layer channel coding schemes, involving retransmission of extra redundant data, become attractive. Application-layer, adaptive rateless channel coding is exploited in this paper´s scheme to reconstruct streamed video across an IEEE 802.16e (mobile WiMAX) channel. The paper concentrates on the trade-offs in implementing the scheme, showing that exact calculation of the redundant data has the potential to reduce the forward error correction bit-rate overhead. To reduce delay an appropriate compression rate should also be selected.
