Extended Internet Group Management Protocol (EIGMP), which allows us to efficiently utilize channel streams being broadcasted for other viewers in shared networks, was recently proposed to reduce the Channel Change Response Time (CCRT). This involves a cross-layer approach to implement. In this paper, we propose a method to implement EIGMP in Gigabit Ethernet Passive Optical Network (GEPON) by modifying its Media Access Control (MAC) and IP layers. With the proposed method, each ONU can control Ethernet frames encapsulating IP packets for the EIGMP by using Logical Link Identifier (LLID) in the MAC layer according to the Channel Mapping Table (CMT). Analysis shows that the proposed method can reduce the CCRT by up to 9.4% in comparison with the traditional IPTV system by assuming that a selected channel is being broadcasted for other users through the same fiber.
