Design and implementation of wireless STB in DTV over EPON system

Abstract

In this paper, we proposed to integrate WLAN technology with DTV over EPON system to provide wireless service to the DTV set-top-box(STB) for end user. First of all, the whole wireless DTV over EPON system architecture is introduced. There are mainly three parts: the accessing part, EPON system and the wireless receiving part. The working mechanism of each part is also described. Then, the paper focus on the design and implementation of the receiving device: wireless STB. The key point of the design is to integrate WLAN chipset into a normal DTV STB to enable wireless transmission. Hardware design is discussed in detail and software design is also mentioned in the last part of the article. Finally, conclusions are drawn out: WLAN signal could satisfy the transmission bandwidth requirement of DTV over EPON system. The proposed system can work properly.
