Digital Videos Broadcasting via Satellite – Challenge on IPTV Distribution

IPTV distribution on DVB-S. The two basic types of multicast distribution trees provided for IPTV distribution are source trees and shared trees(O’Driscoll 2008). A source tree is based on the principle of identifying the shortest path through network from source to destination. Due to the fact that source trees identify shortest path, they called shortest path trees (SPT).
