For the purpose of 3G streaming media applying, this paper introduces the principle of the streaming media, and then designs embedded streaming media playing terminal. The hardware uses ARM processor to control other chips, and DM64X for audio and video hard decoding; the terminal modifies Linux kernel as the operating system; the construction of streaming media player software uses layer method and modularity in application. Audio and video decoding calls hardware interface directly, so the software has good extensibility and decoding performance. All in all, the streaming media playing terminal owns advantages of low price, strong performance, high universality and good extensibility.
