Abstract: A mobile terminal based intelligent music player system is designed to solve the space and time limited problem. The system consists of two parts:the mobile terminal software APP and the server that includes a router, an intelligent network set-top box and audio equipment with timed playback and mobile real-time control playback function. The system is implemented by using STUN based NAT traversal way remote control and home TV network set-top box. This can not only achieve timed play of home audio, but also can control the music play through remote mobile terminal. In addition, the song's remote update can be realized and the playback time can be controlled and changed freely. Experimental results show that the system works well, and has broad application prospects and commercial value. This paper takes the family music player system as an example to illustrate the design.
