Abstract: The embedded streaming media player which is based on the technology of Internet and streaming media is developing rapidly for its simple using and convenient carrying. However, there are so many problems in the design of the traditional embedded streaming media terminal, such as cost, performance and algorithm’s upgrade. A hierarchical, modular design scheme is proposed which is based on the S3C6410 microprocessor as the core and the overall consideration of the multimedia processing capability of hardware and the upgradability of software. Meanwhile, the P2P play mode is introduced into the terminal to make the terminals share the video streams at short range and reduce the load of the server. The management mechanism of streaming media terminal cache space, the adjustment strategy of streaming data downloading speed and the design of playback process are discussed in detail. The feasibility of the program is verified by experiment.
