Abstract (en)
[origin: WO2008114936A1] Provided is an MDU broadcasting signal distribution system that receives a broadcasting signal through a single broadcasting receiving antenna in a multiplex house or building where an IP network is provided and then transmits the broadcasting signal to each MDU set-top box through IP network. In a user side, a set-top box is connected to a broadcasting signal converting device so as to receive a broadcasting signal through the broadcasting signal converting device such that broadcasting can be provided. According to the invention, when an IP network is provided in a multiplex house or building, a set-box is connected to IP network through a broadcasting signal converting device without a dish-shaped antenna or cable being separately installed. Therefore, broadcasting signals are more effectively distributed to each home, and users can watch desired broadcasting. Further, as IGMP is applied, broadcasting can be selectively provided to set-top boxes belonging to a specific group.
