基于嵌入式Linux的车载多媒体广告机设计

摘要

Aiming at the limitation of traditional vehicular multimedia AD player, a design method of vehicular multimedia AD player based on embedded Linux and Qt/Embedded is proposed. S3C6410 is adopted as the central processor in the hardware and the software platform uses Embedded Linux operating system. Additionally, the interface is developed by Qt, which is a type of open source graphical user interface library. The system adopts MPlayer as its media player. After experimental veriifcation, the AD player has the characteristic of low cost, user-friendly, quick reaction, and has a signiifcant improvement in cross-platform and scalability.%针对传统车载多媒体广告机的局限性，提出了一种基于嵌入式Liunx与Qt/Embedded的车载多媒体广告机的设计方案。该方案采用以ARM处理器S3C6410为核心的硬件平台和以嵌入式Linux系统为核心的软件平台，并在此基础上采用开放源代码的图形界面库Qt开发广告机界面，同时利用开源播放软件MPlayer作为播放器。经实验验证，该多媒体广告机具有成本较低、界面友好、反应灵敏等特点，并在跨平台性、可扩展性等方面比传统方案有显著改善。
