In this paper, we propose a distributed IPTV system by which each program provider (PP) possess a light-weight software-based IPTV head-end station, and subscribers watch an aggregated IPTV channel. In the proposed system, 1) each media belongs to the distributed PPs is automatically streamed at a scheduled instance; 2) each streamed media can be aggregated in real-time according to scheduling information, and delivered to subscribers in the form of a single IPTV channel.
