The paper presents a novel embedded multifunctional media sever (EMMS) for mobile devices to receivevarious media programs. Being different from other contemporary system research, the paper mainly studieshow to design a reception solution for terrestrial digital television (DTV) on mobile devices and how toenable mobile devices can receive DTV program, enjoy video-on-demand (VOD), achieve video surveillanceand relay Internet video program via local Wi-Fi simultaneously. In the system design, we integratebroadcasting-terrestrial DTV tuner, streaming media re-transmission system, VOD disk, video camera andaccess interface to the Internet into EMMS, which can either receive terrestrial DTV radio signals anddemodulate out digital transport stream (TS), or can read streaming media bit-stream from VOD disk,surveillance camera or access interface to the Internet. The experimental results show the proposed system isstable and quality-efficient. Comparing with the other systems, the proposed system has the least packet lossrate and response time.
