The Design And Implement Of Wireless Stream Media Player Based On Embedded Linux

In this dissertation, a wireless streaming media player is designed.This system is developed based on customization embedded Linux operationsystem. and hardware on X86 industry-control . the stream media technology ,MPEG-4 technology,MP3 technology are used in designing the system By this Media player, we can use the VOD all over the wireless IanThe most work in this dissertation are followed:1) a comprehensive description about the interrelated technology of the embedded stream media player is given, Summing up the specific design of the system;2) Detailed design of the system overall program, building a embedded Linux operating system based on the X86 low-power embedded motherboard, the principal tasks include: to guide the selection process, the kernel of tailoring, file system establishment and the design of the shell. System software is divided into four modules: the main control module, communications module, decoding module, interactive graphics and for each module we give the design.3) Effectively the transfer buffer zone is designed and resolve the uncertainty of the network delay.4) Audio and video synchronization Mechanism is used by comparing with the system time which could overcome the shortcomings of the interdependence of audio and video.5) Introducing a system concrete realization, building a required software process on the I0WA-GX-R11 embedded motherboards; introducing the detail of the module part of the streaming media player.
