In this paper, a system of digital television over EPON is first introduced. System structure and working process are described in detail, including technology scheme of each part. According to DVB-C, digital TV signal is first received, then TS streams are de-multiplexed and decrypted and so IP stream made up of TS streams is transmitted in EPON. Then, as the most important terminal device on the side of users, STB receives Ethernet data, gets the MPEG-2 TS through network processing. After that, STB parses TS file, decodes video and audio, analyzes SI data, and sends the gained data to TV to display video and EPG. Besides, STB fulfills the web browser. According to the function of the system, technical requirements and main scheme of an IPTV STB are analyzed and realized. It's based on AMD Au1200 processor with Linux operation system. The hardware and software architectures are introduced, together with functional description of every part. We realize all modules required and the experiment shows a good performance of facility and stability.
