Abstract
Provided is a digital broadcast system that receives digital broadcast services on a passive optical network (PON). The data separator separates a signal input thereinto from the outside into an Ethernet frame for data service and an Ethernet frame for digital broadcast service. The Ethernet switch transmits the Ethernet frame for data service to an optical network terminal (ONT) provided in the user's home according to header information of the Ethernet frame for data service. The channel request processor receives the user's channel selection request information and user identification (ID) information from the ONT. The digital broadcast processor transmits the Ethernet frame for digital broadcast service, corresponding to the digital broadcast channel selected by the user, to the user's ONT, by using a part of bandwidth assigned for an existing line.
