基于ARM和Android的智能電視系統(tǒng)研發(fā)
[Abstract]:In recent years, with the rapid development of embedded technology and the promotion of the concept of Internet of things, more and more devices are connected with "intelligence" and "network". Intelligent TV is the product of this trend. The so-called intelligent TV is a kind of digital TV which has an intelligent operating system and can be connected to the Internet, where users can watch video online or install and uninstall programs provided by third-party service providers to expand television functions. Intelligent TV function is becoming more and more powerful, at the same time, the requirements of hardware configuration and operating system are also higher and higher. In this paper, a high-end intelligent TV solution is implemented based on the ARM architecture and Android operating system. The main processing chip of the scheme is Marvell's 88DE3100 multimedia processing chip. The main CPU of this chip is a dual-core CPU, chip compatible with ARMv7. It also has several audio and video processing modules. The version 2.3 of the Android operating system is Gingerbread.. In this paper, the hardware design and software design of intelligent TV are described. The hardware design includes hardware system management module, image processing module, audio processing module, video processing module, digital rights management module and external storage module. Software design includes system boot module, system status, operating system startup process and multimedia processing framework. At the end of the paper, the updating process of the system, the optimization method of eMMC storage and the improvement scheme of UBoot burning process are studied respectively.
